We weigh up Anglian vs Everest, examining the pros and cons of each company. Note: Everest went into administration on 24 April 2024 and was acquired by Anglian in May 2024.
Both Anglian and Everest were founded in the 1960s with the aim of producing high-quality double glazing windows, and today they are two of the leading replacement window companies in the UK. Covering England, Wales and Scotland, they both offer a range of styles, materials and optional extras, such as safety or obscuring glass.
Whilst Anglian and Everest still operate as separate brands, Anglian acquired Everest out of administration in May 2024, so both are owned by the same parent company, Anglian Home Improvements (ASHI Group Ltd), who also acquired Safestyle UK in November 2023.
In this guide, we pitted the two window providers against each other, analysing what they offer customers, including prices, frame materials and styles, guarantees and safety measures. With all of this information in mind, you can decide which brand is best for your needs.

Both Anglian and Everest produce windows on a made-to-measure basis, so the prices shown below are estimated based on these average window sizes:
It’s worth noting while comparing prices that both companies require a deposit for window installations: 20% for Everest, and an amount that varies on a quote-by-quote basis for Anglian.
| Cost (excluding installation) | Anglian | Everest | Cheapest |
|---|---|---|---|
| uPVC casement | £275 | £550 | Anglian |
| Aluminium casement | £550 | £685 | Anglian |
| Timber casement | £925 | £825 | Everest |
| uPVC sash | £415 | £825 | Anglian |
| Aluminium sash | £825 | £1,025 | Anglian |
| Timber sash | £1,390 | £1,250 | Everest |
| uPVC 3-section bay | £700 | £1,375 | Anglian |
| Aluminium 3-section bay | £1,375 | £1,710 | Anglian |

Anglian offers a £250 discount on installation when you request a free, no-obligation online quote.
Everest offers triple glazing for the price of double glazing windows and a multi-buy discount when you buy two or more products, including doors, conservatories and driveways. The brand also runs a 7-Day Price Promise, guaranteeing to match any better offer you can find within a week of receiving a quote.
Anglian’s prices beat Everest’s in all double glazing window categories except for timber frames. However, Everest’s Price Promise means you could potentially buy their windows at the same price as Anglian’s double glazing if you get a cheaper quote from Anglian.
The costs for installing replacement windows vary, as Anglian and Everest use fitters that are local to the project.
When considering the cost of double glazing, it’s worth remembering that there are government grants and loans available for those who qualify to help with the cost of home improvements.
Anglian offers credit options from a representative 11.9% APR over a term of 36 months, with a minimum deposit of £199.
Everest offers loans through Kandoo up to a maximum of £250,000, with flexible lending periods of up to 25 years (representative 9.9% APR).
Whether Anglian or Everest’s finance options are best for your household depends on your financial situation.
At 10 years, Anglian’s parts and labour guarantee matches the industry standard. The brand also has a 15-year guarantee on their gas-filled sealed units; considering all their units are gas-filled and sealed, the guarantee effectively covers all their double glazing windows.
Everest’s guarantees are a little more complex than Anglian’s and are broken down into several potential threats, depending on the range and frame material chosen. Their guarantee for standard uPVC windows, the most popular choice, expires after 10 years (unlike Anglian’s 15-year cover), and only their premium Exclusives range benefits from a 20-year guarantee. Purchase from this range, and you have the option of adding on lifetime condensation cover for an extra cost.
On a like-for-like basis, Everest appears to offer more cover. Anglian’s guarantees are broader and don’t consider that certain frame materials are more likely to deteriorate over time than others. For example, timber double glazing windows from Anglian are guaranteed for 15 years as they are gas-filled units, whereas from Everest, they would be covered for 30 years.

uPVC, aluminium and timber framed windows are offered by both Anglian and Everest, in similar styles. Everest’s range of glass types is focused on the homeowner’s peace of mind, with options for safety and noise reduction glass, which don’t feature in Anglian’s catalogue.
While both companies provide a bespoke service allowing you to choose the style, glass type and frame material, Anglian offers a shaped window option and can produce square, circular and triangular windows. Combined with their decorative glass catalogue, they deliver a more appearance-focused service.
Although both Anglian and Everest produce a wide range of options for creating replacement windows that are fully adaptable to your requirements, Anglian seems to have the edge if you’re after a more stylish appearance. If you are troubled by external noise, double glazing windows with Everest’s noise reduction glass may be a better choice.
| Anglian | Everest | |
|---|---|---|
| uPVC | A (option to upgrade to A+) | A+ |
| Aluminium | Not listed | Not listed |
| Timber | A and B | A |
All double glazing windows are given an energy rating based on their thermal efficiency, in the same way that domestic appliances are. The ratings awarded are independently verified by the British Fenestration Rating Council (BFRC) and can give you an idea of how much you can save from your heating bill. A++ denotes that the windows offer the highest energy rating.
Both Anglian and Everest replacement windows provide excellent energy efficiency, well above the current FENSA regulations for newly installed windows, which state they should have a minimum rating of C.
Anglian has an A rating on uPVC windows, with an optional upgrade to A+. At the same time, Everest is rated A+ on their uPVC models as standard. Both companies’ timber frames are slightly less efficient, with Anglian offering A and B rating options and Everest A. Neither company’s website states the energy rating of their aluminium frames, but as they tend to be less efficient, it’s assumed this is the case here.
Everest is the winner in this category, with a rating of A+ on their uPVC windows and A on timber double glazing. Remember, too, that at the moment Everest offers a free upgrade to A++ triple glazing on their uPVC windows.
Secured by Design (SBD) is a police-run scheme designed to improve the security of domestic and commercial properties.
Anglian and Everest have both considered security in their window designs and have included internally fitted beading, which prevents the glass from being removed from outside your home, and key locking handles. Anglian has gone one step further with its anti-jemmy design, which stops anyone from removing the entire window frame from the outside.
While Anglian windows have two steel shot bolts that secure them closed, Everest’s GrabLock produces the same effect by using a rotating cylinder to ‘grab’ a long bar discreetly fitted inside the frame. However, this innovative lock is only on their uPVC double glazing windows, and the other styles have a multi-point locking system instead, which appears to be similar to Anglian’s two-point shot bolts.
Anglian and Everest offer similar levels of security, with both brands providing premium security features and hardware.
According to a survey by Which?, the customer service and aftersales support provided by Anglian are awarded 4 and 3 stars respectively, with 84% of customers saying they were satisfied with the service given by Anglian. The overall score given by Anglian customers was 67%. Here are some quotes from Anglian customers:
“Have had their products in the past and they have always been reliable. Any minor problems have been addressed immediately. Although more expensive than some other firms, their products are well made and robust.”
“Very minor remedial work to some trim – under guarantee so the company dealt with and resolved. Should have been noticed by the installers but there was prompt action when I mentioned what was missing.”
Another survey by Which? awarded Everest the same scores for customer service and aftersales support as Anglian. However, a higher percentage of customers questioned said they were satisfied with the service provided by Everest (90%). The brand’s overall customer score was 73%. Here are some quotes from Everest customers:
“They are a really good company with knowledgeable staff and great quality products that are very affordable and worthwhile.”
“It was overall a very easy purchase. Great offers, lots of choices and a company that is very easy to deal with.”
Anglian and Everest received the same star rating from surveyed customers, but with a higher percentage of satisfied customers and a 6% greater overall score, Everest is the winner here.
Both Anglian and Everest have been accused of mis-selling and misleading customers in the past; however, judging by their recent reviews on Trustpilot, they have bounced back and are offering a quality service.
Anglian has a Trustpilot rating of 3.9 stars out of 5, although it’s worth noting this is for all of its home improvement services. The company has 59% of 5-star reviews, and 18% of 1-star reviews.
Most recently, it has received many 4 or 5 star reviews, however some dissatisfied customers highlight a lack of after-sales care and unresolved issues with their window installation. Anglian replies to all reviews on Trustpilot, but some customers report not being contacted by customer service teams after their complaint.
“I was very impressed. The windows look really great. The builders were efficient, they cleaned up after themselves. All told, a great service.”
“Darren and his colleague did an efficient, tidy, thorough job installing 9 different windows over 2 days. Andreas followed up with a quick call and was very helpful and polite. Well done to all involved, thanks.”
“The installation date was completely mishandled, causing a delay of over a month. I was mis-sold triple glazing as a soundproofing solution, but it actually made things louder due to the trickle vents. Scaffolding has been left up for months after the original installation date, with no follow-up. One of the windows has a visible chip in the exterior glass.
The installers pre-ticked confirmation boxes and folded the paperwork to hide this before asking me to sign – a dishonest practice. I’ve sent multiple emails trying to resolve these issues, all of which have been ignored.”
“Window fitted. Caused damaged to internal wall. Fitter left without installation of silicon seals. He also left silicon pipes in the road.”
Everest has a 3.5-star rating on Trustpilot, with 70% of 5-star reviews and 18% of 1-star reviews. While most recent reviews about installations are positive, there are reports of very pushy sales techniques, poor after-sales service and some customers have had issues with Everest’s warranties.
“From start to finish an excellent experience, the consultant did a fabulous job giving us all the options and demonstrating the benefits of the Everest window system, now they are installed I am so glad I made the choice to use Everest. Thank you to all the team I love my new windows.”
“We had two special-feature windows replaced satisfactorily. We were quite satisfied with the quality of the design and installation, including erection and dismantling of scaffolding.”
“We had a salesperson, Nima, who came to do the assessment straight away and recommended a Double window promising us we could forget about condensation and wall staining with the Everest Window.
After instalment we had 2 issues: 1. the door frame was scratched, so we had to book a technician more than a month later to come and wax the frame (it took me calling almost every day the customer service to get a date booked in, because nobody was answering any email). 2. We have a massive condensation problem, with water dripping from the bottom of the frame, resulting in both wall and wood floor staining in a flat that has just been repainted with floor just sanded.
To date, the company is still not able to advise on the resolution of the condensation issue, when they should have installed vents in the frame from the get go, considering that window is the only opening we have in the whole upper floor. We had the technician come over and also advised for the need of vents, whilst their head-office only says there is nothing they can do.”
While Everest clearly has a higher percentage of 5-star reviews, the overall ratings are similar, making this a close call.
After examining all the criteria above in depth, our team recommends contacting Everest to install or replace windows.
Although Everest was more expensive overall, if you make use of their Price Promise, you should be able to purchase their windows for the same price as Anglian’s. Across the rest of the categories considered, Everest came out on top in nearly every case, including on guarantees and customer service.
