Modern windows with an authentic look for an older house
We replaced some rather tired single-glazed leaded light windows in our top storey with Heritage's Conservation Slimline (double-glazed) aluminium windows. Our house was built in the "arts and craft" style in 1913 and it is important that the windows retain an authentic look (including leaded lights). We are really pleased with the result and the fitters - led by Paul - were exemplary. Well done to the team!
Very professional - will use again.
The entire process from quotation to installation was professional, punctual and seamless. Our large bay window was installed during challenging weather in mid-February and the team were clean, tidy, efficient and very courteous. Would definitely recommend and use again for our 90 year old house retrofit.
Professional from start to finish…
The sales and survey team were professional and had that knowledge that comes from a wealth of experience. The installation team were superb, tidy and cleared up and cleaned up each day.
We are delighted with the finished job and the product which exceeds expectations.
New upstairs landing window successfully installed
New upstairs landing window successfully installed to replace an old window where the wooden frame was beginning to rot away. Everything went very smoothly: from the ever-patient salesperson who provided several quote permutations, to the detailed measuring up, very efficient erecting of scaffolding by the team, and finally the two installers on the day who were very tidy, polite and skilled in their work. Interaction with the office admin/installation coordination teams was equally efficient. Not the cheapest quote or quickest time from order to installation, but a reassuringly professional job was done. I have used them before and am highly likely to do so again if I need new windows.
Excellent service from start to finish
Excellent service from start to finish. Delightful team installed the windows and the end result could not be better The new windows haven’t changed the character of the old cottages but have made them significantly warmer. Definitely 5*
The team did a great job for us
The team did a great job for us. In particular, Dan Kelly was committed to ensuring a high quality outcome. He solved the challenges with thoughtful professionalism and honesty. All of the team were polite, diligent, hard working (despite the elements) and tidy inside and out of our home.
Repeat satisfied customer
We had most of our windows fitted by Heritage Windows in 2001 and we decided to finish installation on the side of the house which we couldn’t afford then. As expected the service level is very high from the salesperson to the architect to the office admin and to the fitters. Our original windows had a colour finish that was not available with the updated colour charts but this was not an issue for them they mixed and matched so all the windows in the house both old and new have the same finish. We have no problems recommending them unconditionally. Great job and professional finish
Guaranteed a brilliant experience
Its hard to know where to begin writing this review. It's so rare these days to be able to say that a company have given exemplary service from start to finish but Heritage Windows have. I absolutely have to applaud the internal structure of the business because without fail everyone we have dealt with - from the quote, to surveyor, to installers and accounts teams have been incredibly kind, courteous and effective in their role. We had anamazing account manager Luke. The few issues we did have he went to tremendous efforts to visit and resolve on the day, he's always checked in to make sure we're happy with the solution without requiring any prompting - and just seems to continually go above and beyond.
The windows themselves are flawless, beautiful and in keeping with our 1930s house. This was our biggest (and therefore most anxiety inducing purchase!) and if this is how you're feeling then please take this review as a sign to go with Heritage - if you have half the experience we've had, you'll be delighted.

Beyond expectations
Our apartment is top floor of difficult to access building. Windows last replaced in 1980s. Taking advantage of scaffolding erected for other purposes we booked THWC for quote, then survey, then job to replace all our windows. It’s been beyond our wildest expectations. Great windows, beautifully fitted , friendly/ no-fuss team and excellent comms throughout. And so little to do internally post installation.
Polite efficient installers
Polite efficient installers. Very pleased with the new windows as we have draught free quiet rooms we had hoped for. The scaffolders unfortunately broke a pane of glass in the front door on removal of scaffolding which was a concern but was fixed within days.
Poor advice, poor quality
Poor advice - they advised it would be ok to remove the passive ventilation. Now we have mould.
Cost increases - the price kept going up and up until we committed. In weeks.
Finally, 2 years post instalation - handles don't work, fittings falling off.
I regret ever looking them up.

First Class all round
This was the last in a series of window upgrades on our Art Deco house by Heritage. Once again an excellently produced product. The surveyor was first class (as before) and the work was to a very high standard. We had to rearrange dates which was done efficiently and courteously. Work completed well within the estimated time.
We had already used Heritage Windows…
We had already used Heritage Windows previously some years before and were very happy with the product and service we received then . We had no hesitation in returning to them once again when another part of our house required re fenestration . A great team from start to finish .
Great service
Great service, great speed, good job
Scaffolders could have been quicker taking scaffolding back down after what was just 2-day job. We told the Monday but wasn’t till the Thursday.
Good quality windows
Good quality windows, installed without leaving any mess, I would recommend them, a good job all round from Jenny in the showroom to the sales and surveyor and Martin who installed them.
