Everest windows review: best installer for transparent pricing
We know that the cost of double glazing is a significant investment, and that is why we recommend comparing multiple quotes from installers to secure the most competitive price. Factors influencing the cost of double glazing should include window style, material, location, and the installer's reputation.
In our detailed Everest windows review, we consider essential elements such as pricing, guarantees, national coverage, and customer feedback. For a comprehensive overview of other installers and typical UK window prices, check our broader list of the best double glazing companies.
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.

FAQs
While double glazing is the usual choice for a home outside of a heavily restricted planning area, triple glazing could be a good option for some buyers, especially those in windy locations or those on busy, noisy roads. Expect to pay 15-30 percent more than for double glazing.
These windows are heavier and available in fewer styles. Finding triple glazed windows in timber and aluminium is difficult.
What is the average cost for double glazing?
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.

Woody Johnson completes purchase of Crystal Palace shares
Crystal Palace have confirmed that Woody Johnson's purchase of Eagle Football's shareholding in the club has been completed. American businessman Johnson – who is co-owner of the New York Jets – joins chairman Steve Parish, Josh Harris and David Blitzer as a partner and director of the Eagles, and has also signed the Premier League's Owners' Charter. 'I am honoured and privileged to be joining the ownership group of Crystal Palace Football Club,' Johnson told the Eagles website. 'It is an organisation with a proud history, tradition, and deep roots in English football in South London, which I came to admire during my time as US Ambassador to the United Kingdom. 'Eagles fans have demonstrated extraordinary loyalty, passion, and unwavering dedication and I am excited to meet and get to know them. 'I have great respect for Steve Parish and the leadership he has provided over the years. 'I look forward to working with him and the entire ownership group to build on the club's recent successes and help shape an exciting future for Crystal Palace. 'This is more than an investment – it's a commitment to realising the vision for the club, the community, and the culture around Selhurst Park.' Johnson's arrival at Palace comes with the club in dispute with UEFA over which European competition they will play in next season after winning the FA Cup in May. The Eagles were demoted from the Europa League to the Conference League after falling foul of UEFA's rules governing multi-club ownership, but have submitted an appeal to the Court of Arbitration for Sport. UEFA determined that as of March 1, American businessman John Textor had control or influence in Palace and French club Lyon. Textor said he had agreed to sell his stake in Palace to Johnson, but the move came too late to satisfy UEFA. Parish said: 'At this exciting time for Crystal Palace, we are delighted to be welcoming Woody to the ownership of the football club, and we very much look forward to working alongside him to build on our historic recent success moving forwards.'

FA issue England manager warning ahead of Euros final
The Football Association (FA) is determined to retain Sarina Wiegman as England manager, with chief executive Mark Bullingham stating she is "not for sale" at any price. Wiegman has reached five consecutive major tournament finals, including the last three with the Lionesses, and will lead them in the Euro 2025 final against world champions Spain. Her current contract with the FA extends until the end of the 2027 Women's World Cup, and Bullingham expressed confidence in keeping her in charge. Bullingham praised Wiegman as a "special coach" for her exceptional tournament record, work with players, and ability to maintain a cool head in critical moments. He dismissed suggestions that Wiegman should be considered for the England men's job, asserting it is disrespectful to view the men's role as more senior.

Iconic fashion chain plans UK high street RETURN after going bust and shutting 46 stores
AN iconic fashion chain is planning to make a triumphant return to the high street next year, The Sun can exclusively reveal. Ted Baker is set to make a comeback to the British high street in early 2026, sources close to the matter have said. It is understood the brand is planning to return to London, with more details to be confirmed closer to the time. It's not clear yet how many shops there will be or whether there will be any outside the capital. The news comes more than a year after the much-loved brand dramatically collapsed and shuttered all its stores in August 2024. Founded in 1988, Ted Baker was well-known in the 90s for its clothes and accessories with bold and floral designs. A decade ago it was one of the strongest names in the retail sector with 550 shops and concessions around the world - but has recently ran into major difficulties. Shoppers were shocked when the fashion giant fell into administration in March last year. It brought back its website in November last year, stocking a range of menswear, womenswear and accessories. The website currently ships to the UK only but it says it will offer international shipping "very soon". The Sun has approached Ted Baker for comment. What happened to Ted Baker The company's troubles first began in 2019 after its founder Ray Kelvin quit his role following allegations of harassment. Fashion chain to shut all shops It then put out several profit warnings, which is when a company advises the stock market that profits will be lower than expected. In 2020, the retailer said it would axe 160 jobs. More bad news came in March 2024 it collapsed into administration, putting dozens of stores and hundreds of jobs at risk. By then the company had 86 stores across the UK and 975 employees. No Ordinary Designer Label (NODL), owned by Authentic Brands Group (ABG) and trading as Ted Baker, appointed Teneo as administrators. NODL blamed a deal going sour between its owners and a Dutch operating partner that had allegedly promised to inject cash into the business. By April, Ted Baker had announced it would close 15 stores with the loss of 120 jobs. The Sun exclusively revealed in July 2024 that the brand was at risk of disappearing from the high street forever within weeks. It was then announced that the last of Ted Baker's 31 stores would be closed for good in August. The brand launched huge clearance sales to get rid of its final stock, with at least one store advertising at least 70% off everything. Shoppers raced to clear the shelves of glamorous maxi dresses, winter coats and men's suits at bargain prices before the stores shut forever. Other iconic brands that have come back from collapse Ted Baker wouldn't be the first brand to make a dramatic comeback to the high street. Shirtmaker T.M. Lewin announced last month it would be opening more stores in London, Manchester and Edinburgh. The brand had fallen into administration and shut all of its 66 branches in 2020. Last year, fashion and homeware chain Cath Kidston made a surprise return by opening a store in Westfield White City, London. The retailer had crashed into administration and shut all of its stores in 2023. Wilko also made a high street comeback with stores in England, Scotland, Wales and Northern Ireland almost a year after it went into administration. Meanwhile fashion chain M&Co opened a new store in Scotland a little more than a year after it collapsed. What does going into administration mean? WHEN a company enters into administration, all control is passed to an appointed administrator. The administrator has to leverage the company's assets and business to repay creditors any outstanding debts. Once a company enters administration, a "moratorium" is put in place which means no legal action can be taken against it. Administrators write to your creditors and Companies House to say they've been appointed. They try to stop the company from being liquidated (closing down), and if it can't it pays as much of a company's debts from its remaining assets. The administrator has eight weeks to write a statement explaining what they plan to do to move the business forward. This must be sent to creditors, employees and Companies House and invite them to approve or amend the plans at a meeting. A Notice of Intention is used to inform concerning parties that a company intends to enter administration. It is a physical document which is submitted to court, usually by directors aiming to prevent a company from being liquidated. Like with a standard administration process, a Notice of Intention stops creditors from taking out any legal action over a company while they try and rectify the business.
