Why choose Clearview Windows?
Area covered: The northwest of England, including North Wales, West Derbyshire and South Lakes
Founded: 2008
Guarantee: 20 years on products (roofs, PVC frames, doors, and glass), 10 years on aluminium and building work
Best for: Long guarantees and award-winning service
Clearview Windows stands out for offering a generous 20-year product guarantee, which is significantly longer than the industry standard. What's more, installation and building work are still covered for 10 years.
Focused on the North West, Clearview has earned recognition in the industry, including Installer of the Year award three years running at the the Glass & Glazing Federation's G-Awards.
While timber frame options are unavailable — a common limitation for regional installers — Clearview Windows offers a wide range of modern uPVC and aluminium windows, including its own Extreme brand of A+ rated energy-efficient products. These windows are regularly featured in promotional offers, with up to a third off during sales.
Clearview Windows is also known for its attention to design. Its conservatory offerings span everything from classic white uPVC greenhouse-style builds to sleek, contemporary extensions.
However, the firm also has a good selection of windows, including casement and flush models for uPVC and slimline aluminium frames for a modern look.
Flush casement windows, as the name suggests, sit flush to their frame, rather than overlapping it like a regular uPVC model. Some buyers find that these look neater.
Customers can visit showrooms in Preston, Nantwich and Warrington, or arrange a design consultation at home.
As with its competitors, financing is expensive, and either paying in cash or getting a cheaper loan is probably a better financial choice. If you are ordering a conservatory, a three-month interest-free option is available, but this does not apply to windows or doors.
All products are manufactured at the company's factory in Yorkshire, ensuring local quality control and faster delivery.
Clearview Windows financing options
Clearview offers financing, though rates may be higher than alternatives. If budget allows, paying in cash or securing an independent loan may offer better value.
Clearview offers a number of financing options. You can order today with a 20% deposit and spread your cost over 60 months with an 11.9% rate of interest.
For windows and doors, the company offers the option to place your order with a 20% deposit and pay nothing for three months, with interest at 10.9% when payments start.
On living spaces, you can pay just £99 deposit and pay nothing for 12 months; however, the interest rate when payments start is 19.9%.
Pros:
20-year product guarantee on many items
Good customer feedback
Multiple showrooms and design consultation options
Cons:
No timber options
Focused on North West region only
Limited price transparency online
What to look for in a quote
According to our research, the average three-bed house should cost about £4,500 to fit with new double-glazed uPVC windows, depending on location and window sizes.
It's important to haggle, perhaps more than many with other purchases. Windows are more of a buyers' market, since unless the panes themselves are broken, it's a purchase you can put off, at least for a little while.
This gives you the upper hand and allows some time to research the best price and options.
Depending on the installer and how tricky your installation is, you may be able to shave up to half off the initial quote you are given.
This may seem unlikely, but it's true. That's because many firms rely on Britons' general discomfort over asking for discounts to make expensive initial offers. They also rely on their competitors doing the same.
Smaller outfits that feel they need to be more competitive may not be able to drop by as much – use your judgement.
As well as this guide, it is also worth getting personal recommendations. If a company has done a good job at a fair price for a friend or colleague, they will probably do the same for you.

FAQs
Double glazing is usually sufficient for most UK homes, particularly those not located on busy roads or in exposed, windy locations. Triple glazing offers better insulation and noise reduction, but it comes at a higher cost — typically 15–30% more — and with fewer style options, especially for timber or aluminium frames.
These windows are heavier and available in fewer styles. Finding triple glazed windows in timber and aluminium is difficult.
The average cost of a new set of eight uPVC windows for an average three-bedroom home in the UK is currently about £4,500, according to research by The Independent.
The price you will pay for a new set of double glazing depends heavily on the style, materials, colours and glazing type of your windows, together with how many you need and where you are in the country.
Most buyers opt for white uPVC, which is a type of plastic. It does not rust or rot, an advantage over wood, and it is cheaper than aluminium, the other popular low-maintenance material. It also doesn't bend like aluminium can.
