Frontier Windows Reviews 

Vik and his Team did Window installations at my property as part of a refurb.

Vik and team did a great job ! My work wasn’t easy but they made the adjustments . The installers were really good and they finished the job

Very efficient. Fully explained process to me. Very quick turnaround. Turned up on the date as booked. Very tidy. Left the house clean. Explained everything to me and ensured I was happy with the windows before leaving.

We recently had our windows and doors replaced, and we’re very pleased with the results. The work was very nice and has completely changed the look of our house. It feels brighter inside, and the exterior has a much cleaner, updated appearance.

The workers were friendly, professional, and got on with the job efficiently each day. They worked well together, kept everything tidy, and made sure the installation was done properly. The new windows and doors fit perfectly and operate smoothly. Overall, it was a positive experience, and we’re happy with the quality of the finished work.

Excellent service and Quality product.
I am extremely happy the way they dealt from survey to finished job. Excellent Quality of windows and double doors Finesse in finishing is beyond imaginations.
Overall work well done.

Be aware, don’t pay fully until you are satisfied with the job.
Had windows and doors fitted in July 2025 and fitters were very professional and polite.
Georgian bars on some windows panes were missing. It was meant to have 3 but it only came with 2 also front door lock was supposed to be a security lock but it came with normal lock.
Fitters and office guaranteed that it would be all sorted by following week but that never happened.
Contacted them several times and always told that someone will come and fix it but no one ever did.
So haven’t been chasing them for a while because of health problems but I don’t believe they will do anything about it.
As soon as they have the second and last payment they don’t bother with customer service.
Also the Fensa certificate that were promised never arrived.
Obviously a comboys outfit so be aware that sometimes they will do as little as possible to maximise profits.
It shouldn’t have cost them much to rectify the windows bars as it was a factory mistake and not theirs so I believe the factory would have swallowed the cost of the parts, and they probably would have spent a couple hours fitting new glass panes which would just be labour cost for them.
Had this review up a couple months ago and company contacted me asking to remove it and they would come on 4 February 2026 to rectify problems.
Obviously this review is going back on as they haven’t came as promised and refused to answer phone, messages and emails.
If this happens to someone else which it will please don’t remove negative review until they fix your problem.

If you’re on the fence — just do it. The new doors completely transformed the look and feel of my home. Solid, secure, and beautifully finished. The installers were friendly, efficient, and clearly knew what they were doing. Everything fits perfectly and works flawlessly. Couldn’t be happier with the upgrade.

From the first call to the final walkthrough, everything was handled with professionalism and care. The team showed up on time, explained the process clearly, and completed the installation without any hassle. The windows look fantastic and you can immediately feel the improvement in insulation and noise reduction. It’s rare to find a company that delivers exactly what they promise — this one truly does. Highly recommend!

Title: Refund Only Processed After Credit Card Intervention

Review:
I placed an order with Frontier Windows Ltd and paid a £500 deposit. During the survey, the company confirmed they could not meet my requirements, and we mutually agreed to cancel the order. I confirmed the cancellation in writing within 7 days, in accordance with their Terms & Conditions, and was advised the deposit would be refunded.

Despite this, no refund was issued by the company. I sent multiple emails and a formal complaint by recorded delivery, but the refund was only recovered after intervention by my credit card provider under Section 75.

This experience highlights the importance of carefully checking customer service and refund policies. I hope Frontier Windows improves its processes to ensure other customers do not face similar delays.

Great quality windows, really happy with the installation and the team.
They were efficient, on time and just a lovely bunch; from the point of sale to installation.
Thank you guys

Excellent work and even better customer service! They came highly recommended and did not disappoint!

Thank you for all your help!

Great experience with Frontier Windows and excellent customer service. Would highly recommend to friends and family.

I had my windows fitted this week, the whole experience was seamless, friendly and professional. So happy with the end result. The new windows look great and really made my house come together, can’t recommend them enough.

Keep up the good work guys

I would 100% recommend this service to anyone looking to get windows fitted. Vik and the team were friendly and professional, maintained consistent communication and got the job done quickly and perfectly.

They are truly experts at what they do, as can be seen by the amount and quality of information they provide you with during the decision process- they are genuine and honest people trying to advise you based on your own individual window-fitting needs (and their instincts can definitely be trusted because our windows look great!)

All in all, the team at Frontier Windows have excellent customer service skills, they're very knowledgeable about the product and will provide exceptional results, guaranteed.

great services and best quality windows in budget price. I would recommend.

I’m still waiting for Frontier Windows to respond to me. I placed an order several weeks ago and paid a 50% deposit based on their 3–4 week installation timeframe and assurances that the windows were already in production. That timeframe has long passed, and despite sending multiple emails and follow‑ups, my messages have been ignored. I’ve received no confirmed specification, no installation date, and no meaningful update on the order.

The lack of communication has disrupted other trades and falls well below the expectations set at the start. I’m still hoping this will be resolved, but at the moment it has been extremely difficult to get any response from the company.

Update13.01.2026
After receiving a request from Frontier Windows to amend my review (I still haven’t received all the promised information from them) I gave them an opportunity to redeem themselves by sending me the information required for my planning permission, as it was delaying the installation. Despite further reminders to them, I’m STILL waiting for a reply and the requested information!

The whole team was very cooperative and knowledgeable
Understand my need and explain everything in detail
Installation done on time
Will definitely use them for any future

Frontier Windows did an excellent job from start to finish. The team was professional, communication was clear, and the fitting was absolutely immaculate. The new windows have already improved the comfort and efficiency of my home, and the price was fair enough to put a smile on my face. Big thanks to Vik and Awais — I’d definitely recommend Frontier Windows for quality work and great service.

I recently had Frontier Windows install new uPVC windows, and I’m really happy with the whole experience. The team was friendly, professional, and explained everything clearly from the start.

The installers did a brilliant job—arrived on time, worked neatly, and the finish is spot on. The windows themselves look fantastic and have already made the house warmer and quieter.

Communication was great throughout, and the whole process felt smooth and stress-free. I’d definitely recommend Frontier Windows to anyone looking for quality uPVC windows and reliable service.

After looking around for a trustworthy company to upgrade my home, I chose Frontier Windows—and I’m genuinely glad I did. I had five UPVC windows and an aluminium bifold door installed, and the whole experience was excellent.

A big mention to Awais, who handled the sales side. He was incredibly informative, honest, and helpful, making sure I understood all my options without any pressure. His guidance made the decision process so much easier.

On the installation side, Vik was fantastic. His communication was clear and consistent, and he kept me updated throughout the entire job. The installation itself was done with real care and attention to detail. The UPVC windows look great and have already improved warmth and noise levels in the house. The aluminium bifold door is stunning—smooth to operate and a real transformation to the space.

The team worked efficiently, respected my home, and left everything clean once they were done. It’s rare to find a company that combines professional service, quality products, and great customer care, but Frontier Windows really delivered.

I’m extremely happy with the results and would highly recommend Frontier Windows to anyone looking for new windows or doors. Excellent service from start to finish, with special thanks to both Awais and Vik for making the experience so smooth.
