1st Glass UK Reviews 

This company was recommended by a friend who used their service before. We engaged with them to install a sliding door in between our conservatory and lounge. Throughout the whole process, from the first visit, quotation, measurement and installation, everyone have been very friendly, helpful and patient. We have to change our initial installation date and there was no issue at all. And when they couldn't make it for the scheduled installation date (due to overrun work), they informed us early and we were happy to reschedule again (I guess that made us 1-1 😅). Finally, during the installation day, Lee, our installer came on time and install the door single handedly! He was very friendly and his work is beautiful. The best part is he cleaned the place up after the work is done. Price wise I think it's reasonable. Definitely will recommend to everyone looking to install a door or windows.

Lee who fitted my front door was a gentleman and clean worker.made a good job of my front door.and now ive ordered a french door.i also need my windows changing .but will do them later with 1st glass.

Excellent friendly,family run firm makes one feel at ease from the unhurried discussions,planning and scheduling to specifications.
Particularly pleased with the door quality and workmanship put into it along with immaculate fitting by Lee.
Already booked with the firm fir another family project!.
I would thoroughly recommend them.

Absolutely amazing service from first glass uk from start to finish. Very polite professional. Product was absolutely spot on no issues fast installation no messing about.
Workmanship amazing Stuart and Dan both very professional polite informative and very tidy. Will definitely use these again for my windows

Very pleased with our new external doors , the fitters was very professional ,made sure everything was to a high standard and cleaned up after themselves .

Chris, Anthony and Alex installed 2 bedroom windows and 1 patio door in my kitchen. It was a difficult job for them as my house is 3 stories with no access to the back garden!! However they completed the job very professionally and cleanly, would recommend and use this company again

From day one, everything started off brilliantly. Mo came to quote us for our windows and was extremely professional. He wasn't pushy at all, answered all of our questions, and made the whole process feel straightforward.

The fitters, Mick and Nigel, were absolutely fantastic. They were professional, friendly, worked to a very high standard, and left everything clean and tidy. We couldn't fault their work.

Unfortunately, from that point onwards, the experience went downhill. Once the windows were fitted, every pane of glass had scratch marks and needed replacing. Since then, it's been constant back and forth trying to get the issue resolved, with repeated delays and broken promises.

We were told replacement glass had been ordered, only for someone to turn up a day earlier than the agreed appointment with just two panes instead of the four required, meaning everything had to be reordered. We were then booked in again, but nobody turned up on the scheduled day. Today, another installer arrived with only two panes because, apparently, the other glass couldn't be found in the warehouse.

After being promised by Andy on the phone yesterday that everything was there and ready to complete the job, I called him again this morning. He admitted he didn't want to let us down after all the previous mistakes. However, I would much rather nobody had attended than have someone arrive knowing the job couldn't be completed properly.

To make matters worse, when I questioned this, Andy's response was, "Well, you've got the windows, it's just the glass." I found this dismissive and unprofessional. We've paid £4,000 for these windows and expect the job to be completed to the standard promised. We shouldn't have to keep chasing, rearranging our time, and dealing with excuse after excuse just to have brand-new, undamaged windows installed.

It's a real shame because the sales experience and the fitting team were excellent, but the after-sales service has been incredibly disappointing and has completely let the company down.

Great friendly and informative service from Lee. Fantastic experience and professional service from Lee and all of the team at 1st Class doors and windows. They also do other services (ie.canopys).
1st Class by name means real 1st class service 👏. 30th June 2026.

Nice no nonsense company finished products look fantastic

The service was excellent. Lee who fitted the door was top notch showed me the workings and cleaned up as he went along. Top class company. I know where I'll be going if I need anything in the future. 5☆☆☆☆☆

Chris and Anthony fitted my new front door. They were hard working efficient and cleaned up after themselves. Delighted with my new door.

I have had all of my windows, doors and French doors fitted by First Glass UK. More recently I have had my porch sprayed to match the windows and doors in Chartwell Green.
Tom did an excellent job, no mess, and very polite.
I would highly recommend First Glass UK as the staff are friendly and polite and the work is carried out to high standard whilst good value for your money.

From the first contact we had a good experience. Mo the salesman was very friendly and polite. No sales pressure he just asked what we required and gave us a quote. We agreed the price which we thought was reasonable .
We then got a follow up call to arrange the surveyor visit.
The installation date was agreed. On the day the fitters Anthony and Chris arrived on time. They were nice,polite and friendly. They respected our property and did a great job. This was on one of the hottest days of the year. They finished and did a good job of clearing up leaving minimal cleaning to do.
Would definately recommend this company.

From beginning to end we were kept informed of what was happening step by step. Lee and the surveyor were extremely friendly so were the fitters Adil & Junaid. I have employed them again to sort my windows so hopefully the next process will be as good 😊 Thanks to all of you @1st Glass

I could not recommend 1st glass more highly! From initial sales meeting, through to completion they did everything they said they would! I was called when they said they’d call, they arrived when they said they were going to arrive. Really top quality product, custom design of stained glass work completed too - nothing was too much trouble! The fitting team, Rob & Dave were incredible, and I certainly don’t envy them working on the hottest week of the year! Thank you again to the whole team, would not hesitate to use you again. In fact, you’ll be the first people I call.

Would highly recommend this company Thank you Ivan & Shaun for my insulation of my back door they did a great job and was very polite
Love my new door

From start to finish what a great experience. We had continuous updates throughout the whole process, plus aftercare. Every member of staff we had dealings with were polite professional informed and friendly. Would particularly like to mention Lynn who was our first port of call she came to the house and was very Informative in helping us choose our new doors, Lee the fitter who did a fantastic job and cleaned up after himself and also Lee in the sales office who has been very helpful.
We would recommend 1st Glass for outstanding work and customer service. Looking forward to getting our windows done will write a new review following that.
1st Glass 1st Class

After months and multiple doors been sent out to be fitted .Im still no where near getting a door that hasn’t got imperfections on it ie wrong colour,dents in door ,chips in door ,not colour matched properly with window frames being different colour to the door.They have turned round to me and said I am being picky

It’s not picky it’s wanting a front door that looks new not a second hand one . I was assured the one sent out today to be fitted would be 100% inspected before leaving the shop . It got to me with a bent in it and jagged edges again and wrong colour
Now they are telling me my first door that was fitted is the wrong colour, its not the colour I ordered . We have now had 3 different green colours sent out to us .All came with dents in them .Stressed and frustrated is not the word for how I feel .This company I would never ever recommend to anybody and the door I ordered wasn’t cheap.

The installer Lee came, he was very polite and professional,he introduced himself, he made the job look so easy he cleaned up after himself, and payed attention to detail, I was absolutely satisfied with job.. Well done.. I have other things need doing and as soon as im ready im sure I will be calling...money well spent...

I can't thank Gaz and Reece enough for the great job they did putting the new door up. They even left the place spotless and not many people do that. They are well trusted and caring. I would get them to put another door up for me. They do deserve a bonus.
