Why choose Everest?
Everest is a familiar brand to many, thanks to memorable TV campaigns in the 1980s and 2000s featuring installations at the Tan Hill Inn, Britain's highest pub.
But the company has had a troubled history in recent years, entering administration in both 2020, during the Covid lockdowns, and again in 2024. Everest is now under the ownership of Anglian Home Improvements.
Its financial instability previously left some customers with unfulfilled warranties and the inability to cancel orders. Fortunately, Everest's new owners honoured purchases made just before the collapse.
Everest provides a broad selection of window options, including uPVC, timber, and aluminium. Its user-friendly website also lists doors and conservatories.
Despite this, Everest's financial troubles and mixed customer reviews rank it lowest among the companies we've evaluated.
However, a significant positive for Everest is its transparent pricing guide, a rarity in the industry and indeed unlike any other firm we have reviewed.
Standard uPVC casement windows range from £700 to £1,800 per window. Sash windows typically cost around 50 per cent more, tilt-and-turn models 25 per cent more, bay windows 150 per cent more, aluminium frames about 25 per cent more, and timber around 50 per cent more than uPVC.
Readers should note that these prices are the company's asking prices and should be taken as a starting point for negotiations. Buyers should view these as a starting point and aim to negotiate downwards by 25 to 50 per cent, particularly if paying upfront or commissioning additional work.
Everest says its windows are now triple-glazed as standard, enhancing heat retention but adding approximately 10 to 20 per cent to the overall cost.
Financing options are available through Everest, but with a steep interest rate of 12.9 per cent, it is advisable to consider using savings or exploring loans from high-street lenders offering significantly lower rates.
Pros:
Transparent pricing
Triple glazing as standard for uPVC
Cons:
Expensive
Mixed customer reviews
Went under twice in recent years
What to look for in a quote
Based on our research, fitting new double-glazed uPVC windows in an average three-bedroom hom e should cost approximately £4,500. Location, window sizes, and styles will affect this price.
It's important to haggle. Windows are more of a buyers' market because, 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. Given the competitiveness of the double glazing market, buyers have considerable leverage to negotiate. Take your time and do thorough research to secure the best price.
Quotes from larger installers may initially be inflated, relying on consumer hesitation to negotiate. However, smaller installers, eager to secure business, may have less room to offer discounts.
Seek personal recommendations when possible. Companies that provide fair pricing and reliable service for others will likely offer the same to you.

These windows are heavier and available in fewer styles. Finding triple glazed windows in timber and aluminium is difficult.

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.
