Sash Windows London Anmeldelser 

Double glazing can be both costly and confusing, but Sash Windows London made the process much easier. Their London store showcases a variety of models, which really helped us visualise our options. The customer service was excellent, guiding us through every step.

We had one of our windows customised with an arch, and it turned out beautifully!

Overall, I highly recommend them. If you're unsure, visiting their London store is a great way to get started.

Excellent service, very happy and would recommend!
I was pretty apprehensive about getting new windows since it's a big decision and a large amount of money. I got a few quotes and went with Sash Windows London Ltd because the person who came to do the initial inspection, Bryn, was very personable and explained everything with very minimal pushy sales tactics which I had received from other companies.
It wasn't the cheapest quote I got but the reviews made me feel reassured and being able to visit the showroom was super helpful and the woman there also explained everything very clearly.
After booking the windows in and paying the deposit all communication by email was clear and they were very responsive, this has continued throughout.
The installers, Mirel and Ivan were great. They were very polite and approachable and did a fantastic job installing the windows generally. They cleared up very well themselves so there is minimal tidy up for me to do which is ideal.
The windows themselves look fantastic and seem to be a really high standard and fit perfectly.

2nd time for me, had back windows done six years ago. I still got three quotes but chose SWL based on my previous experience. Front windows done, already proving their worth. Front bedroom still warm despite radiator not working. Excellent service, great products working together for customers.

I had a full set of new windows for my flat in SW London. Great experience from start to finish from initial consultation through to completion.
Fantastic value, compared to many other companies I got prices from and a great service.
Very friendly installation team and amazing quality windows. They look stunning in place!
Definitely recommend!!

We were so impressed with the job they did on our neighbours windows, There was never the question of deciding who to hire. They are very professional, skilled and efficient. The quality of the product is superb and the job they did was first rate, including clearing the site after they had finished.

Very professional. An excellent experience all round: quick, easy, and extremely polite. Very helpful advice on best options for the property as well as decent follow up. Highly recommended.

Great service from the get go. I felt confident that going with SWL was the best option and glad I did - the secondary glazing installed in our flat as significantly reduced noise and thermal leaks.

Fantastic experience from start to finish. They visited and were excellent in talking through options and answering questions. Very well organised and responsive. The work is excellent quality. Great installers.

Choosing a company to install new windows is often difficult as there are a myriad of operators..I hit on the Sash Window Company a couple of years ago and was immediately struck by their professionalism, care and competitive pricing, and I was rewarded in my choice by the outcome. Two years on I am having further work done, and I have encountered the same level of customer care, and importantly to me the same personnel in place to help.

My whole experience replacing two sets of sash windows with Sash Windows London was excellent. The estimate turnaround was fast, communication was good, they finished the work in the two days proposed and when their was a small niggle, they were helpful and responsive with the fix.

Fantastic windows and excellent service.

I am not a reviewer in general but felt like it was only fair to endorse such a positive experience. I have high standards and feel forever let down by disappointing trades people, messy or unreliable even when they have sold us the dream. This experience upheld its promise from start to finish. We are thrilled with the end product and recommend them unreservedly. Thank you again!

They are honouring the 10 year warranty to deal with minor defects noted. Happy to recommend them and share the new photos of repairs.

Danny and Darry were great! The entire process was so smooth, no delays, no changes, no unexpected fees. Great job

The company delivered a fantastic service. I was initially sceptical about choosing UPVC sash windows rather than wood sash. However the quality is amazing and it is hard to tell the difference. The sales process was really easy and unlike other companies I spoke to I didn’t feel like I was under any pressure. It is clear the company was confident with their product which sells itself. After agreeing to move forward the process was extremely smooth. Installation went ahead as scheduled. I had other trades on site and they were impressed with the professionalism and attention to detail of the operatives. I was extremely happy with the whole service. I have already recommended the company to a neighbour who is also moving forward with replacing his windows. The company is not the cheapest but this is a clear example of you pay for what you get both in terms of service and quality of the product.

We had two windows replaced recently with double-glazing and Sash Windows did a great job. They were always punctual and professional with communication and the quality of the windows is fantastic. Would definitely use them again.

Almost 8 months ago I had new windows fitted in my flat by Sash Windows London, and I couldn't be more pleased with the results so much so I had them return to fit a new door this month. From start to finish, the service has been exceptional.
The team is highly professional, arriving on time and working efficiently throughout the entire process. They took great care to ensure everything was installed perfectly and left the place spotless afterward.
The quality of the windows and door is excellent, and I have noticed a significant improvement in both insulation and noise reduction.
Communication with James Couch was seamless, he provided clear explanations and options, making the entire experience stress-free.
Overall, I would highly recommend Sash windows London to anyone looking for high-quality window and door installation. Their workmanship, professionalism, and attention to detail were outstanding.

The whole experience with Sash Windows London was excellent from start to finish. I visited the showroom in Battersea and the sales representative talked through the different options. I was keep informed of the installation date and provided very useful information of what to expect on the day.
The installation team arrived on time, they were very professional and friendly. They ensured they cleaned up after the work was completed and ensured I was happy with the job before departing. A pleasure to have worked with a professional outfit.

The installers were great—very client-focused, tidy, and courteous with good workmanship. Very pleased with the quality of windows. However, I was a bit disappointed with the sales team as they didn't allow for (Scaffolding ) access to remove and install the windows, and I had to make a separate payment for this, albeit at a discounted rate. At the time of placing the order, I was told that I would be getting moulding to replicate my neighbour's, which didn't happen. When I flagged this up, no one came back to me with a solution until it was too late and the job was finished.
