About Everest

Everest is a long-established brand installing conservatories, windows, and doors across England, Wales, and Scotland with made-to-measure products.

Everest operates as a home improvement specialist and now trades as part of ASHI Group, which also owns Anglian and Safestyle. Their focus is on residential upgrades – think windows, doors, conservatories, and orangeries – serving homes across the UK.

Their services go beyond just glazing. They also handle:

• Security system installs
• Artificial grass fitting
• Bespoke home enhancements

Everest’s Trustpilot profile is polarised: 2.7 out of 5 across 13,500+ reviews, with most reviews 5-star but a sizeable minority 1-star.

That history comes with a caveat: the previous Everest company, Everest 2020 Ltd, entered administration in April 2024, and the brand now trades under ASHI Group.

Everest Pricing and Charges

Everest does not publish fixed prices – all quotes are custom. Promotions of up to 50% off selected windows and doors run periodically.

Everest doesn’t do one-size-fits-all prices. Since everything’s custom, you won’t find a price list on their website – each quote is tailored after an assessment.

They do run promotions on their site, though. Sometimes you’ll see discounts up to 50% on selected windows and doors, which definitely helps if you’re watching the budget.

Primary Product Offerings

Everest offers five window styles in uPVC, timber, and aluminium, plus Victorian, Edwardian, Cheltenham, and York conservatory designs with A+ double glazing standard.

Glass Installations

Everest offers a broad selection of window solutions aimed at boosting thermal performance and cutting down on maintenance. Their installations feature energy-efficient glazing to help keep your home comfy all year.

You can pick from five window styles to suit your taste:

• Casement windows – classic side-hinged
• Sash windows – vertical sliders, perfect for period homes
• Secondary glazing – extra insulation for existing frames
• Tilt and turn systems – modern, European-style
• Dual turn options – open in multiple directions

Materials? Three main choices. uPVC frames are great for insulation and come in finishes like white, charcoal, sage green, and wood-grain. Timber is ideal if you want that natural, heritage look. Aluminium gives you a modern vibe and loads of strength.

All their windows come with A+ rated double glazing by default. If you want to push it further, there’s A++ triple glazing for even better insulation and noise reduction. This could save you a bit on energy bills.

Entrance and Access Solutions

Their door range covers everything from front doors to rear access and special installs. Each is designed for curb appeal and solid security, with warranties to back them up.

Front doors use composite construction in both modern and traditional styles. They’re built to exceed British Standard security and you get a lot of colour options to match your taste.

Bi-folding doors are all about opening up your space. These multi-panel systems can retract fully, making them a hit for garden-facing rooms. The frames are reinforced, so they’re tough but still glide open smoothly.

Patio doors come with a few handy features:

Garage doors? You’ve got four styles: roller, sectional, one-piece, and side-hinged. All focus on durability and security, with solid locking systems.

Glass Room Extensions

Everest conservatories are a big part of their business. These aren’t just for summer; they’re designed as year-round living spaces.

The structures use uPVC frames and plenty of glass to let in light, but still keep things snug inside. Full-height windows give you those garden views, and the weatherproofing is pretty advanced.

Conservatory designs come in four main styles:

• Victorian – fancy details, bay fronts, decorative ridges
• Edwardian – clean lines, square or rectangular shapes
• Cheltenham – modern, with sleek architecture
• York – a blend of traditional and contemporary

Every conservatory project includes design consultation, help with planning permission, and making sure everything’s up to code. They’ll sort the groundwork and see the job through to the end.

Modern conservatories are insulated enough to use as lounges, dining rooms, or even home offices. The technical side lets you pick between double or triple glazing, and sealed units are guaranteed against fogging (check the term in your quote).

Orangeries are the premium option, with extras like dwarf walls and lantern roofs. They sit somewhere between a classic conservatory and a full extension, but still let in tons of light.

Customisation is a big deal at Everest. You can tweak dimensions, colours, and design details so your new space fits right in with the rest of your home.

Customer Feedback for Everest

Everest holds a 2.7 out of 5 “Average” Trustpilot rating from 13,000+ reviews, with praise for installation quality but recurring criticism of after-sales delays.

Everest holds a 2.7 out of 5 rating based on 13,000+ reviews, so it pays to read recent feedback carefully before committing.

Positive Customer Experiences:

• Installations are high quality
• The workmanship is professional
• Most folks are happy with the end result
• Projects get finished reliably

Common Customer Concerns:

• After-sales service delays – repairs can take a while
• Communication issues – sometimes hard to get hold of support
• Missed appointments – engineers occasionally don’t show up

There’s plenty of praise, but after-sales support isn’t always smooth sailing.

Customer Service and Contact Options

Everest’s quotes line is open 8AM–9:30PM weekdays and 9:30AM–8PM weekends, with live chat and a separate complaints line during business hours.

Everest gives you several ways to get in touch, depending on what you need. There are different phone lines for different enquiries.

If you want a quote, their phone lines are open 8:00 AM to 9:30 PM on weekdays, and 9:30 AM to 8:00 PM on weekends. For order updates, there’s a separate line open weekdays from 9:00 AM to 5:00 PM.

For complaints, there’s a dedicated line during business hours on weekdays. No weekend support for order updates or complaints, though.

If you’d rather not call, live chat is available too – a handy option if you just want a quick answer.

Evaluating Everest Against Competitors

Everest sits at 2.7 out of 5 on Trustpilot and shares a parent, ASHI Group, with Anglian and Safestyle, so quotes from the three are not independent price competition.

When you stack Everest up against other big names, a few things stand out. They hold a 2.7 out of 5 Trustpilot score across 13,000+ reviews – a rating that reflects highly polarised feedback, with strong praise for individual installers offset by after-sales service complaints.

Anglian, SEH BAC and Wickes each have their own Trustpilot profiles, so check the current score and read the recent reviews for each before you compare. Everest’s 2.7 out of 5 is a polarised rating, mostly 5-star or 1-star, rather than a uniformly middling one.

Most top-tier providers, Everest included, don’t list fixed prices.

Everest is among the more established names, and their national coverage means you can get a local consultation pretty much anywhere in England, Wales, or Scotland.
