  ⭐⭐⭐⭐⭐ An absolutely exceptional experience from start to finish. The quality of both the products and the service has been unrivalled, and every single member of the team has been a genuine pleasure to deal with. Alan in Sales was fantastic — knowledgeable, helpful and professional throughout. Kierra in Billing was equally brilliant and made everything straightforward and easy. A special mention has to go to the fitting team, Ewan and Tyler. Their workmanship was of an exceptional standard, and their professionalism was second to none. They were a joy to have around — polite, respectful, tidy and clearly took great pride in what they do. The finished windows look fantastic, and the quality is outstanding. From the initial sales process right through to the fitting and aftercare, the whole experience has been first class. We honestly couldn’t recommend this company highly enough. Exceptional people, exceptional products and exceptional service — absolutely delighted with the result!

  We had replacement windows throughout and a new front door from St Helens Windows, installed on June 8, 2026. Everything went brilliantly from the very start - from when the rep Alan came to measure and price (who was not at all pushy, just very nice and helpful), from phone calls and communications with the company, to the actual installation. All excellent. The team arrived on time - Ewan and Tyler - and got stuck in promptly with enthusiasm. The whole process took only two days. At the same time the company installed a new front door for my son at another local address, and he was equally happy with the entire process. I would not hesitate to use the company again in the future for any further work required and would wholeheartedly recommend them. Thank you once again to all at St Helens Windows.

  Very good information on the order taking visit and on the measuring up visit. Quick service from order being placed to the instalation date. The removal of old fittings and fitting of replacements was completed in the set time and to a very high stanadard by the fitter and he made sure that he kept everything neat and tidy. The total service from first visit to completion of the job was first rate and we could not of been more satisfied. WELL DONE  to all concerned.

  I have a semi-detached bungalow with a total of 8 windows and external doors. Not wanting every room to be done all at once, I broke the work down to 4 visits. This meant I had a lot of contact with the sales team, office staff, surveyor and installers. The Sales staff were always very helpful, contacting me by emails and phone calls. The Surveyor was always punctual and thorough, always giving me an expected time of arrival. The two installers worked well together, treated my home respectfully, worked to a high standard and cleared up all their mess. The total price was also competitive. I have no hesitation in recommending St Helens Windows to others wanting to upgrade their windows and external doors.

Upgrade To Energy-Efficient Double-Glazed Windows

Our double-glazed windows are designed to improve energy efficiency throughout the year.
Two panes of insulated glass help reduce heat loss through your windows.
Improved insulation can help keep your home warmer in winter and cooler in summer.

What Is The Advantage Of Double-Glazed Windows?

Double Glazing FAQs

Double glazing consists of two panes of glass separated by an air or gas-filled gap. The layer functions as insulation, minimising heat loss, boosting energy efficiency, and offering superior noise reduction compared to single-glass windows.

Double glazing improves insulation and can help your home achieve an A+ energy rating. Lowering heat loss in winter and keeping your home cooler in summer may help lower your energy costs over time.

Are White uPVC Windows Cheaper?

In most cases, white uPVC windows are the most affordable window option available. They are typically cheaper than coloured uPVC finishes, aluminium frames, or traditional timber windows. The reason is simple: white uPVC is the standard material used in window manufacturing, meaning it requires fewer additional finishes or treatments during production. Coloured uPVC windows often involve specialised foils or coatings, which increase the manufacturing cost.

Why Many Homeowners Choose White uPVC Windows

Lower cost compared to coloured uPVC, aluminium, or timber
Low maintenance – no repainting required
Strong durability and resistance to weathering
Good energy efficiency when paired with modern double glazing
A classic style that suits most property types

White uPVC windows remain one of the most popular choices for replacement windows in UK homes.
