Ordered a door and frame in March.
Day before fitting was advised it’s changed to day after
-Door arrived, incorrect fan light
-Fitter ripped out and threw away original Edwardian architrave and damaged plaster work, all without my knowledge or authority
-pieces of plastic architrave were used instead of one for the door trim
-fitter didn’t finish the top of door
-fitter didn’t finish bottom of door
-silicone was used instead of correct sized trim
Complained and advised would be sorted
3 appointments booked, ALL 3 cancelled the day before
Fancy number 2 arrived, wrong again
After 4 months of asking and emailing and calling, I finally had a fitter arrive with correct fan light
Fitter did correct some of the mistakes but my original architrave has been left for me to sort our
Midnight after the last fitter left, I had to evacuate my home due to a massive gas leak. Neighbours had to join me including a child
Complained and asked for my emergency gas safe engineer costs, to be covered!
Promised they would, still waiting for the payment.
Asked for refund, was told they don’t do refunds or compensation
Door is also the wrong colour.
DO NOT USE 1st GLASS UNLESS YOU WANT TO BE LEFT WITH SUBSTANDARD WORK, HOME VANDALISED & OUT OF POCKET

Today we had the front and back doors replaced. We are really happy with the end result. Lee fitted them both, he completed a brilliant job. First class workmanship.
We are really happy with the service and the quality of the doors. We chose this company, because they were so helpful and friendly, we had a lot of help from Lynn, when she came to see us and measure up, there are so many choices of doors. We know that we chose the right company to fit our superb doors.
Thank you to everyone involved.

I'd rate my experience with 1stglass UK as a 3.5 out of 5 stars. Although happy with the outcome, we have dropped 1.5 stars due to the sales process, cost and the discrepancies between the door design and the door we had installed. 

The sales process: We found this a little bit of an odd one. The sales individual who visited our home to discuss our door design was quite firm on both my partner and I being in the room to discuss this and review our choices in the door brochure. We have never dealt with a company who required this so even though my partner was happy for me to decide the door design, he had to come downstairs from his work office to be present in the room. The cost proposed for our composite door design we also thought was a little bit steep (£1,950). I asked if we could think on it but the sales individual stated that this price was only agreed for now and would likely fluctuate if we went back to them in the future. We felt a bit of pressure as a result and agreed on the cost and signed the forms. 

Door design discrepancies: Unfortunately, what we agreed at the final design stage was not what we received when installed. On the day of installation, my partner and I were busy working from home and so we had little interaction or discussion with the installation team. Once the door install was complete, I had to sign some forms and the guys left. We had no complaints about the install as they did a great job but it was only after we had finished work that we noticed that it was slightly different to our agreed design. The dental shelf was missing from the door, the door knob was installed in a different location (I was previously informed this would fit in the centre panel of the door but on the install date informed this would not work/fit correctly and thus had to be installed where the shelf was supposed to go) and the escutcheon door pull was not installed. I contacted 1stglass to make them aware of this. It did take a little bit of time and chasing up to hear back but eventually someone came over to make the changes that they could, but unfortunately these were limited due to some of the permanent install choices (e.g. base of the door knob was not the correct size to be fit in initially agreed location, dental shelf could not/would be complicated to install due to the drilled location of door knob). The front door did also drop slightly after install which resulted in some issues with opening/closing the door but this was fixed when someone visited after my above email.

Overall, we are happy with our composite door. The staff were helpful and open to giving advice, communication for the most part was good but there could be improvements in some areas. I'm not sure if I would use 1stglass UK again due to these hiccups and looking back, we would have looked around for other quotes for comparison. However, we thank 1stglass UK for our door and their work.

I couldn't be happier with my new front door from 1st Glass. From start to finish, the service was excellent, and the quality of the door is outstanding.

A special mention goes to Lee, who installed the door. He was professional, friendly, and took great pride in his work. The installation was completed to a very high standard, and he left everything clean and tidy afterwards.

The new door looks fantastic and has made such a difference to the appearance of my home. I would highly recommend 1st Glass to anyone looking for quality products and excellent customer service. Thank you!

Reece and Gary were brilliant start to finish. So professional and went above and beyond to make my porch look perfect. Super friendly, tidy and cleaned up after. Couldn’t have ran any smoother, and their work was top notch. Thankyou

I am very disappointed with the company's response and their complete lack of accountability.

They continue to refer to the contract, which clearly states that a low threshold door was to be installed. The reality is that they have fitted a door with a 70mm threshold, which is not classified as a low threshold. A 70mm threshold is at the upper end of a standard threshold (typically 50–70mm), so referring back to the contract only reinforces my concerns rather than addressing them.

I cannot fault the quality of the installation itself—the workmanship is good. My issue is simply that the product installed is not what was requested or what the contract specifies.

The company's claim that I refused to pay is also misleading. I paid the invoice within half an hour of the installation being completed, despite being unhappy with the product supplied. The only thing I refused to do was sign the completion paperwork because I could not honestly confirm that the installation had been completed as specified in the contract.

Unfortunately, this is a situation that is unlikely to be resolved to either party's satisfaction. My advice to anyone considering this company is to read the contract very carefully and ensure every specification is clearly defined in writing. In my experience, the contract does not contain enough detail to guarantee that you will receive the product you believe you are ordering.

We had our new door fitted yesterday, 21/7/26 i am so pleased with how everything went. 1st Glass have delivered a 1st class service. They said they would ring the day before instalation, they did, the two vuys who attended were very nice, and explained everything regarding the keys and how to register them in case of any replacement needed in the future. Once completed,ther tidied up and left it looking good. I received a follow up call from them today, to ask if we were happy with everything. I would recommend to anybody wanting a professional job to contact 1st Glass you will not be disappointed!

Really happy with the new uPVC front door fitted by 1st Glass UK. The quality of the door is excellent and it's made a huge difference to the look of the front of the house.

Dean and Martin did a great job with the installation. They turned up on time, were friendly and professional throughout, and took care to leave everything clean and tidy once they were finished.

A great experience from start to finish. I'd definitely recommend 1st Glass UK.

Great to deal with - excellent windows and Stuart and Dan were top class fitters. They left everything to a very high standard and spotless. Highly recommended

Gary and Reece installed conservatory glass and front door with side panel.
The quality of products are amazing and no middle man,which means a more reasonable price than the big companies.
We have had 1st glass before and had no hesitation about using them again.
Gary and Reece did a beautiful installation were kind and polite and cleaned up after themselves.
Would highly recommended this family run company.
