  ⭐⭐⭐⭐⭐ 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.

Do Bow Windows Help Increase Natural Light?

Bow uPVC windows offer an elegant and durable window style, designed to suit a wide range of properties. In addition, their energy-efficient construction helps improve home insulation while maintaining an attractive appearance. What’s more, bow windows are also relatively low maintenance, making them a practical and long-lasting choice for many homeowners.

Unlike traditional bay windows, which typically feature a square shape, bow windows have a gentle curved design. As a result, because they extend outward from the exterior wall, bow windows can help create a greater sense of space inside the room. Furthermore, they allow for wider views of the surrounding area, whether overlooking a garden or the street outside.
