I recently had a new sash window fitted in my living room and London Box Sash could not have been more helpful.Jake was absolutely brilliant and talked me through all the options and helped me choose what was right for me. The ordering process was simple and the fiting was carried out in one day and I am so happy with the finish.Would definitely recommend – the care and attention to detail is wonderful.Thank you!

Thrilled with our 3 new box sash windows. The quality of the windows is excellent and worth every penny. I thought the price was very fair compared to other quotes I received given the quality of the wood that is used, the length of the guarantees and the ease of the company to deal with. The process from start to end has been seamless. Everyone we interacted with was superbly knowledgeable, responsive and helpful – from Harry, the sales person who helped explain all the design considerations and options very clearly, Judith in the office helping getting us booked in and Andy, the fitter. Andy consulted us on any bits where needed explaining clearly the decision that was needed and his work was to an excellent standard and he was very clean and tidy and respectful of our home. He also kindly made the suggestion to ask our decorator to angle the external sills as they were flat so that the water runs off which would help avoid any damp issues and improve longevity. His wealth of experience was very obvious and I was grateful for him sharing these pointers and discussing directly with my decorator – it’s something that would never have crossed my mind without his tip. I thoroughly recommend!

Can’t recommend enough.The windows installed seem like they’re a really high quality product. Very good customer service from end to end. They do a really thorough consultation & respond quickly to calls and emails. The day of the installation was easy and the guys who installed were quick and left no dust or mess. Followed up at the end via text, email and a call to check I was happy with the product – highly rate this approach.

I found London Box Sash Windows through an online search.With my previous company, I did not get any Fensa certificate and the quality of the wood was inferior to the one used by LBSW for similar prices.They offer a 10% discount for their Standby Schedule Saving which gives very good notice for the client as well. I am very pleased with my double glazed window and the people at LBSW are very helpful.Christine Haight

Both salesman and surveyor were straightforward, helpful and answered all questions.Installers were very efficient, worked very hard, cleaning thoroughly.Astonishingly job completed in 6 hours.The only failing was forgetting to move a chest of drawers.Judith was friendly, very helpful and reassuring

We are delighted with our new windows. From our initial enquiry onwards everything was dealt with in a thoroughly professional, efficient and respectful way. A special mention of Andy, our fitter, whose craftsmanship and attention to detail was amazing.

Jake provided a great consultation and really listened to my requirements. He was confident, yet gentle with his approach and so knowledgable. I received multiple quotes from providers which honestly felt like a waste of time, as they didn’t seem to listen to my needs of wanting timber only. London Box Sash Windows stood out among them all, especially for their expertise and care in period properties. Really competitive pricing as well! Cannot wait to use and would highly recommend!
Nicholas Black
Can only recommend! Everything went extremely smoothly. The team were always available to answer any questions and walk us through the entire process to get our new window installed. Also very competitively priced.I will be reaching out to them soon to get other slash windows replaced.

Very efficient local team, first to book appointment and good contact from Judith in the office. Very thorough presentation from Jake and ability to offer a discount for speedy installation.Andy installed windows and he was professional & friendly. A very clean and methodical approach.They also have an after service care should anything happen which is very reassuring.I have already recommended them to two friends of mine.

I was very happy with the bespoke casement window they installed in my property. The company also agreed to repair it promptly after a number of years. London box sash install high quality timber windows and seem to care about their customers.

Needed a couple of old aluminium windows replaced with box sashes. Found recommendation for London Box Sash Windows Ltdon Which? Trusted Traders website (where they came top for our local area with over one hundred 5* reviews). Three days after the first phone contact, Jake came to our house to quote for the job. He took his time to take us through the various product options and even brought a sample sash window to demonstrate those options (all without any of the often quite annoying hard selling tactics). The quote price wasn’t cheap but within our expectations, and therefore we decided to go ahead with this company. We were given the option to either go for a scheduled installation date 10 to 12 weeks into the future or to go on a stand-by list. We opted for stand-by and a week later Harry (installation manager) visited to take the exact measurements for the window production and to reconfirm all the chosen options. About 2 weeks later, we were given an installation date.The actual installation was done by Andy over 2 days (1 day per window). On both days he started work at 7.30am, properly preparing the room with dust sheets and covering all carpets, before even touching his tools. He worked both days non stop until about 4pm. Andy was very pleasant to have in the house. He took the time to explain the details of the installation and patiently answered all of our many questions.The best, however, was the finished product. 2 gorgeous wooden box sash windows that are perfectly balanced, so that you can actually lift the solid and quite heavy sashes with just one finger!I wish that we had used London Box Sash Windows Ltdfor the replacement sash windows at the front of our house, a job which we had done about 6 years ago. Although those were of good quality, they are nowhere close to the ones that we had done just now.Without hesitation, I will recommend London Box Sash Windows Ltd to friends and neighbours and only keep quiet about this great company to the people I don’t like …

I have bought windows from London Box Sash twice now – the service is unmatched. Having had quotes from a series of other providers, LBSW kept coming out on top for me. The quality of the windows is extremely high, and they have made a massive difference to the feel of my home. The double glazing is excellent, and the installation was swift and professional. A huge thanks from a very happy repeat customer.
Alan Maiolli Delaney
Outstanding customer service and quality in every aspect and interaction. We ended up replacing all the windows that we could with these guys on the strength of the experience we had with them. Would highly recommend getting a quote from them if you are in the market for windows.

London Box Sash Windows just completed the installation of our new, double glazed windows across our mid-terraced Victorian house. We couldn’t be happier with the experience, from start to finish. Jake took a lot of time during the initial consultation, explaining the options available and impact on costs. We had four quotes in the end, roughly in the same price range and decided to go with LBSW due to their professionalism and responsiveness. Harry did the technical inspection pre-installation and Judith kept us updated throughout the process.At the scheduled day of installation, Audris arrived punctually (on the minute!) and his and David’s work was spotless. They both worked extremely hard, precise and left every room they worked in tidy (we didn’t have to do any cleaning ourselves!). Within a week, all our windows were done, in line with the promised timeline. We could really trust the team and go about our lives and just leave them with a key, which is a great feeling. Also, there was much less redecoration needed than we feared, thanks to the team’s careful way of working.Choosing a firm to work with for new windows was a big decision for us, and I can only recommend LSBW. Our house is much warmer, quieter and with no more annoying draughts, we don’t regret the investment for a second.

Great company to work with. Trustworthy, honest and efficient work ethic.Thoroughly recommend this company.

For some time we have been working towards replacing some sash windows in our large mid-Victorian semi-detached house so as to reduce draft, make some rooms warmer, make window opening easier and hopefully safe some energy cost (although we knew that the payback time against energy cost is long). We had visits from several companies identified with flyers through the door, internet searching and personal recommendation, the latter being for London Box Sash Windows (LBS). It was clear from the start that LBS offered a more personalised service and listened more carefully to what we actually wanted. They were the only company to offer sash-only replacement (as against the whole window and frame) and were the only company to point out that full frame replacement would cause problems with windows where the window frame was integrated with shutters and a plaster cornice.All the pre-installation contact was great, with a very detailed on-site discussion of what was wanted, and the different options. LBS helped us create two windows with reproduction Victorian coloured and frosted glass which look fantastic (see attached photo). A very detailed specification and estimate was sent for checking and acceptance, and then a second survey by the fitting expert to iron out the last few potential glitches.The two fitters were brilliant, changing 8 windows in 4 days, arriving promptly for a 7.30am start, and meticulously clearing up dust and rubbish to leave the house in a very good state each day. They worked with minimal noise and fuss and were receptive to the large number of checks and queries that always crop up during a large job in your own home. They were not the least put out when our plumber turned up a day earlier than expected to refit some radiators. On the final evening we immediately noticed the reduction in noise and draught, and the increased warmth.We would not hesitate to use LBS again and to recommend them to others. High quality full replacement of sash windows is not cheap, but we feel that we have installed an excellent product that has greatly enhanced the comfort of our home, that will last for many years, and that has increased its eventual sale value.

Great service great practitioners 👍🏻For David he was fantastic Fantastic product It has changed the room completely but still in keeping with the period of the house

Fantastic service from start to finish. Jake (sales) spent a long time with us explaining all the details and choices, Judith in the office was very responsive to all questions and Jasper (installation) was a master of his craft! I wouldn’t hesitate to recommend London Box Sash!
Tom Robinson
Absolutely brilliant windows. We looked around the competitors but London Box Sash made windows that looked closest to our originals. Key thing to note in my photos is that the weather seals are white and not black like most competitors. Their customer service and quality professionalism was top notch. Thank you.
Stephen Durkin
I used London Box Sash Windows for two separate installations over the last year and I have nothing but praise for the company. From the initial contact, through the estimating to the final installations, the people I dealt with were polite, informative, helpful, punctual and hard working. We had a mix of sash and casement windows fitted and the product is absolutely top notch. We had some issues with our builder making new openings for the windows but the advice and flexibility with the fitting dates given by LBSW made the process and the overall look of the windows superb. I’ve used a few tradespeople over the last few years and LBSW are by far the most professional and committed. A company based on wonderful craftsmanship and customer service!
Paul Calway
I could not recommend London Box Sash enough. The process from start to finish has been easy, dare I say enjoyable. The quotation period was relaxed, informative and clear. The installation was incredibly considerate, clean and professional. The windows themselves are beautiful – we could not be happier. Look no further, these are the people you are looking for.
Mark Byford
Phenomenal windows and service.We chose to use London Box Sash Windows following a recommendation and couldn’t be happier.The entire process from start to finish was absolutely seamless, from the initial survey, selecting designs that replicated our existing Victorian windows like for like, to the fitting and end result.We were astonished not only by the brilliant quality of the new windows (upgrading from original frames and glass means that the property is now silent, cooler and undoubtedly warmer come winter) but the speed the fitting team worked at and their attention to detail.
Maureen Ellis
We’re absolutely thrilled with our new sash windows in the bedroom! From the very beginning, Jake made the initial survey process a breeze. Then, Judith kept us in the loop and informed us throughout the entire process, which was wonderful. And we can’t praise Anjelo and Rafal enough for their amazing job installing the windows. They really went above and beyond! A big thank you to the entire London Box Sash Windows team for making this experience so positive for us! Also of note is how much quieter and warmer the bedroom is now. The windows not only look great but they really make a difference.
Dick Bird
Excellent quality and service. Having originally wanted one replacement sash window, we were so impressed with the quality of the one we ordered, we went on to order four more. The build quality , insulation and acoustic properties are excellent, and the style fits perfectly into our early Edwardian house. The service was always courteous, communication precise and regular, and the fitting itself carried out with great care and consideration. We are delighted with the windows, which have made a huge difference to our previously draughty home.
Nathaniel Rodwell
An excellent all-round experience; the windows look fantastic and the much-feared compulsory trickle vent is particularly discreet! If we ever need more doing we know where to come.
David Baines
London Box Sash our first choice having consulted widely. We were pleased with the quality of the demo window shown and were able to visit a reference customer not far away. The fact they were London based was a plus. Installation team were great, quick, professional and went the extra mile to make a good job. We’re so pleased with the results; noise is less, warmth notably improved and the windows actually slide open! a fantastic improvement on the old ones!
Terry Doherty
Had the windows fitted over 5 years ago – I called to report 1 of the 16 windows had some condensation between the panes of double glazing. No quibble – they ordered a new window taken from their record and replaced it. The engineer arrived as scheduled – completed the job within 2 hours with no mess. A completely professional job and company. I would recommend them to anyone
Annalisa LF
If I could give more than 5 stars I would!From the first day I met Jake for a quote I knew this was the company I was looking for. Professionalism, patience, competence, passion were all there in front of me and I had no doubt I could trust their work.Then came Harry with his obsession to details in taking measurement in a pretty old house which can be very complex and challenging due to the old and not very even structure.And then the work itself done by my 2 rockstars! Audrius and David have been amazing in fitting the windows; extremely precise, always caring about what I felt or thought about the ongoing works, very clean as well! I was expecting lots of dust and damages to the walls but not at all! Only minor spots here and there which are absolutely normal when carrying out these types of jobs.They also cleaned perfectly the windows after the work was completed, the floors and communal stairs and Audrius even went to my neighbours downstairs to make sure no rubbish fell in their property and if so, he made sure to clean properly before leaving.I couldn’t recommend this company more; my experience has been way over my expectations and I’m so glad there are still companies like this one out there.If you are looking for replacing your sash windows look no further; you know who to talk to!(I’m based in Streatham Common, just come and look around; The best ones you’ll see are mine! ;-)Outstanding experience, thank you!Annalisa

We have used London Box Sash three times and they just do such a great job. The quality of the manufacture, the fit of the windows both in the brickwork and the making good afterwards as well as the sashes in the frames is just top notch. The sashes move so smoothly and seal so well – our flat is just very warm and quiet now. The guys who performed the installation are strong to be able to lift the massive heavy units into position but at the same time they have the finesse to do things to a very high degree of precision to give a top finish (eg the painting and the fitting of the ironmongery). In addition they look after your home and are very polite and considerate. They are not cheap but work to a very high standard and at speed and are worth every penny. Highly recommended.
Jim Wood
Very professional keeping us informed of what they were doing before and during the work. Worked fast and kept our rooms very clean. Excellent finishing. Highly recommended.

I still can’t get over how good these guys were. They somehow managed to change most of the windows in our house in 4 days – way shorter than I thought it would take. The quality of the work is superb – they make the house look spectacular. I expected follow up work to be needed but the patching up they do around the windows makes it look almost as if the were never there. And the team itself was great – so considerate of our house, incredibly polite, and explained everything they were doing. New windows aren’t something we’ll need for many more years but I’ll definitely be a return customer when we do. Thank you!
Steph Faber
An incredibly professional, thorough and well executed service. From initial enquiry, through to survey and then installation. I wouldn’t hesitate to use them again. We made a huge financial investment and it was worth every penny.
Catherine Lloyd
Excellent service, friendly and accommodating. From Judith in the office, Harry for the survey and scheduling the work right through to the fitters, such an easy smooth service.Workmanship is of such high quality. The fitters were so tidy and respectful too. So important when you have people working in your house.Our new windows look beautiful.
Jennifer Porter
Superb from start to finish! When I made my initial call and spoke to Judith, I was impressed by her knowledge and her friendly and professional advice. She arranged for the surveyor, Harry, to visit and I knew then that I had made the right decision when he explained everything clearly to me. I was delighted to hear the new window could be made and installed within 4-5 weeks. Andy came last week to do the work and it was a joy to have such an expert – he left my house without a speck of dust in spite of having removed an old sash window. I now have a beautiful new window which moves freely. I thoroughly recommend this company, who give you an honest appraisal of the cost and the time-frame. Amazing! Thank you, especially to Judith, Harry and Andy.
Judith Hawley
We decided to replace all the sash windows in our drafty Victorian house to improve insulation and thus reduce energy use. As it was a significant financial investment for us, we researched it thoroughly and London Box Sash came out as front runners. We are delighted we went with them. From start to finish, their service was highly professional and completely reliable. All of the staff from sales to installation were courteous and a pleasure to deal with. They explained the process fully and there were no nasty surprises. The installation team were amazing. They replaced 13 separate sashes in just four days. The windows look and feel very smart. Our house immediately feels warmer. We can now turn the heating off completely during the day. The degree of sound insulation is an unexpected pleasure too.I would definitely recommend this company.
Jacobus Lombard
I would not hesitate to recommend the London Box Sash Window Company.From the time that I contacted them in November last year, I have been impressed with the professional way they have handled my enquiry for two large sash windows in a Victorian house.Judith Baichoo fully understood my requirements and produced a thorough specification at a reasonable price. The installation has just been completed. Andy, the installer, has done an excellent job with no fuss and no mess.It is sadly unusual to find companies with the ethos, commitment and standard of workmanship exemplified by the London Box Sash Window Company and the people who comprise it.

We are in the process of ‘future-proofing’ our home – let’s face it, with the rising cost of utilities, this is fast becoming a priority. We live in an old Victorian house with large, single-glazed, sash windows, several of which needed replacing, but deciding what with, was always going to be tricky; plastic windows would obviously be cheaper, but wouldn’t be in keeping with the house and so we looked around at who was making wood sash windows. There is no doubt that this is an expensive route to take, but given how long they last once they’re in, to not do it right first time seemed a false economy. We have so far replaced two windows with TBSW company and you really do get what you pay for; from the start and our first contact with them, we felt confident that we were dealing with people who knew what they were talking about, cared about what they did and were hugely positive about their product and justifiably – the windows are superb. Large, double glazed units that immediately cut the heat loss and sound from the outside and because of the perfectly balanced weights, can be raised and lowered with finger-tip control. The finish is beautiful and totally in keeping with the house. The care and precision with which their fitters worked – the place was spotless when they left – belies the amount of work involved and all the work is guaranteed. It has been a pleasure dealing with them.

I have nothing but praise for this company. A bay window, 4 single sash windows, two casement windows, and two sets of french doors – all installed without fuss and to my complete satisfaction in 3 days!Each person I have had contact with are so impressive: – Jake with his fabulous sample window; Judith who handles all the admin efficiently, smoothly and helpfully ; Harry who is clearly a highly professional surveyor as the windows are a perfect fit; and especially Anjelo and Rafal – the installers who work so hard but with such professionalism and expertise.The quality and standard of the windows and doors and the installation are beyond my hopes and expectations. I was worried that the house would be a wreck after this work as it was so many windows in such an old house already suffering from a few years of neglect – I was expecting walls to need replastering – no curtains, dodgy brickwork etc etc – absolutely not the case. The house is now so warm, and quiet … and also looks 100 times better both inside and out. Anjelo and Rafal are artists! ( sorry Anjelo 🙂 )If you want new windows – contact this company.

LBSW has lived up to all the great reviews we read of them. First class product, great communication from start to finish (incl. during installation). Also, when I said I wanted to pay by credit card they made that possible despite it not being on offer initially. Top notch company with a great product. Highly recommended.
Jan Crozier
We had exceptional service from this company right from the beginning with the quote from Jake, who was very knowledgeable and personable and could not have been more helpful. The windows look lovely – we have waited a long time for the right product to come along as we didn’t want to ruin the look of our Victorian house by installing windows that scream “double glazing”. Well these don’t and if anything we think that they enhance the exterior. The installers deserve a special mention, incredibly hard working, tidy and friendly and their workmanship was exceptional; we have only the odd bit of very minimal tidying up to do and you have to look hard to see where it is needed. They managed to get a large bathroom window replaced without so much as a tiny crack to the surrounding fragile crackle glazed tiles, something I’m not sure even they thought they would be able to do. I can’t recommend this company highly enough and thanks a million to the neighbour of mine who recommended them to me. Please don’t change or be tempted to cut any corners because your service and product are both fantastic exactly the way they are.
Constantine Haberis
‘London Box Sash Windows Ltd.’ clearly stood out as the obvious choice out of a number of other candidate companies for the replacement of three single glazed sash windows with new double glazed ones, in a four storey Georgian property within the London East Canonbury conservation area, in terms of the high quality of materials used, the great safety design features employed, the excellent guarantees offered and their very competitive pricing. The manufacturing waiting time was as planned and the installation was perfect. Overall excellent!
Nicholas Gibbons
I wanted to leave reviews for this company, as I believe they epitomize what a really well run company can do. Excellent product, excellent service, great employees, and reasonable prices.You cannot go wrong with London Box Sash Windows. They replaced back doors and windows in my Chiswick house which is 120 years old. Looks beautiful and has made a huge difference to the coziness already.
Lin Li
I was super impressed by the service. The window fitter was very considerate covering up the whole room and fitted windows with care. I was also reminded before the fitting date, was well informed throughout the whole booking and fitting process. I would highly recommend this company.

We had 8 windows built and installed by London Box Sash in our Victorian terrace. Everything went smoothly, from the first meeting to the installation of the final window, and everything looks and feels great. The big payback will hopefully be in having a much warmer house over the winter period! More than happy to recommend them.
Lizzy Gosney
The Box Sash Windows team were all so professional, informative and skilled from start to finish. Jake gave me all of the information I needed to properly understand the process. He was always on call to help me with any concerns or questions along the way, making me feel reassured. Andy did a fantastic job with installing the windows. He was efficient and clearly took a lot of pride in his craftsmanship. The windows have transformed the rooms. Not only do they look shiny and new, the sound proofing is a game changer. Judith and the rest of the team were really helpful with the admin side of things. I will continue to recommend Box Sash Windows to everyone. Thank you!
