Everest reviews – windows, doors & more | Everest.co.uk Reviews 

Contacted Everest to ask for a quote for 5 windows and a front door, appointment booked and confirmed.

No one showed up or called to say they were unable to attend. I was then called a couple of days after to ask how the appointment was and if I had any questions surrounding the quote. Explained no one turned up to quote and I wasn’t informed no one was coming. They did apologise and asked if they could reschedule which I refused. I wasn’t informed then contacted a week after this to ask if I had any further thoughts on my quote and again I informed them that no one had turned up and I wasn’t informed and confirmed I did not want to rearrange the appointment.

I feel that the staff just aren’t closing accounts when asked and are definitely not talking to each other!! Shame as they are associated with Anglian who have previously been very good but appear useless in the north east/Yorkshire

Reply to you - What you have just replied with will send me in circles, exactly what I’m complaining about, you constantly pass the buck to someone else who then passes it to someone else! Whoever took over after administration should have the decency to sort this out. My husband’s paying you for the next ten years, I’ve given you my name and email and policy number yet you say you can’t find me. Rubbish! Just not taking responsibility.

Please look at previous reviews and don’t be a fool like I was and get swayed for extremely expensive product that breaks in less than a year (just a window handle) that they totally refuse to acknowledge and fix.
Customer service; passed from one person to the next, one email to the next and nobody within this company will deal with your issue.
My friend had all her windows done and her doors for £7,000, we’re paying £11,000 for their product (I wish I’d got more quotes) over the next several years with no after-service care or interest.
Terrible company, avoid.
Should be ashamed of themselves.
I only need a window lock fixing, their product which broke and they’re not willing to help.

We've had half the windows replaced from old metal single glazed to Everest wood grain uPVC and they look amazing. We couldn't be happier. The finish is great and the chaps who managed the installation (Kevin and Ben) were lovely. They protected carpets and furniture and tidied up afterwards. Really impressed. Also impressed by how much of a difference it has made to the warmth in the house! Thank you

The installers Steve and Harrison were exceptional, they were 5/5!

Unfortunately the experience was let down by the tactics of the sales team. 3/5..

Overall 4/5

When the salesman Glen initially surveyed the property he was advised of exactly what we wanted and quoted accordingly. It came out more expensive than other quotes we had received and we made a decision to take our custom elsewhere.

After advising him of this we were then contacted by another Everest employee who after some negotiations by phone agreed to provide the same service for £25,500.00 (including all the doors and windows that Glen had surveyed, and in the wood grain textured finish). We paid an initial 10% deposit of £2,550.00 in early January and arranged a time for the manufacturing survey to be done.

In the interim we made another payment of £15,000.00. The person who came out to do the survey seemed extremely knowledgeable but unimpressed with the initial survey done by Glen and said I quote “he's not done a very good job!” Last week we received a variation of contact letter increasing the price by £6,000.00 to over £30,000.00. This £6,000.00 increase was for three windows apparently missed off the initial survey, additional scaffolding and a change from standard white to white wood grain textured finish (a finish already agreed when we fixed the price at £25,500.00 in January)

For the past four days I’ve been emailing / phoning and going round in circles to see if they can stick to the original agreement or give us our £17,550.00 back so we can go with someone else. The head office / installations team just tell you to get back in touch with the salesperson and he won’t answer so we are in limbo and at the same time panicking having parted with such a large amount of money.

I would like to thank the company who fitted my windows and doors, and the men who did the job were very kind, polite and they cleaned up after themselves, I recommend them very much, and communication was 100 percent the best

Of of Everest's team Steve Courtier attended to an unexpected doorstep issue promptly and to a really high standard. Excellent aftercare is one of the reasons I chose Everest and on this experience I feel my decision to choose them was validated.

Decent products but atrocious workmanship and customer service. They were scheduled to complete my project before Christmas ’25. They brought the wrong lintel for the front window; corrected that but left for Christmas without patching around this window, leaving the inner wall exposed to winter elements (still the same at the point of writing this in Feb); fitted the incorrect door furniture; agreed to replace the front door (not the spec I ordered); left debris inside and all around the outside of my house (I couldn’t open my garage door until I moved the biggest pile) and failed to turn up when scheduled. When their builder finally appeared several weeks later, he hadn’t been given a work list so didn’t bring the materials or equipment required; he only repaired their own poor plastering, none of the other concerns listed and agreed.
I raised a complaint to escalate the issues but this was simply forwarded to the team who’ve continuously let me down. Trying to engage satisfactory communication is like trying to catch water!

I am writing this to warn potential customers against engaging with Everest. My experience has been a masterclass in unprofessionalism, from high-pressure sales "tricks" to a total lack of post-contract support. Initially, I was quoted an absurd £5,500 for secondary glazing on three sash windows. After I rejected this, the price was miraculously slashed to £3,050—on the condition that I sign immediately.

This is a perfidious tactic designed to make you feel you are getting a deal, when in reality, it is simply price gouging followed by a "false" discount. Once the contract is signed, the "friendly" service disappears. The sales representative who chased me daily became unreachable. Instead, I was met by a customer service department that weaponizes the fine print. They use aggressive tactics, threatening legal costs and exorbitant "storage fees" if you cannot accommodate their specific delivery date.

The installation was carried out by individuals who appeared significantly underpaid and completely disengaged. They performed the bare minimum, with no regard for craftsmanship or customer satisfaction.

There are a multitude of negative reviews for Everest online; I deeply regret not taking them more seriously. Do not be swayed by their persistent sales calls or "limited time" offers. Avoid Everest at all costs.

Steve Harrison and Keiron were polite tidy punctual and highly professional throughout

Everest are not cheap but our experience, supply and installation of a new front door, is that the quality is good. The salesman visited us by appointment on time and explained the process thoroughly. The product was supplied within the expected timeframe and the installer arrived on time and did a good clean job. Overall a satisfactory experience.

Twice I booked for someone to come for a home visit for a new front door. Twice I was let down in the same week with a no show, no confirmation of booking or common courtesy to say the person was not coming. Never spoke to an actual person, it was someone, even possibly AI via a message service @ the quote stage to get everything booked in ready for a home visit. Oh well, I have managed to speak with an actual person, booked an appointment so I know where my money will be going. Not with Everest which clearly don’t want any business with poor customer service as well as communication. Appalling. If I could give 0 rating I would.

**Amended** The amount of reviews I’ve read after posting mine of a no show is actually not surprising as well as poor work of those unfortunate people that had work carried out.. am lucky that I’ve gone with a family run business with over 50 years experience in the business and not these corporate cowboys - dodged a bullet

Made an appointment for Everest to come and provide a quotation. Due on Monday at 16:00 and no one turned up.

Phoned back through to the call office and was advised this would chased up with a call back expected.

48 hours later and phoning Everest again since I’ve received no phone call, text or email updating me on why the local rep didn’t show.

This is being ‘followed up’ once again…. Avoid at all costs as this company clearly have 0 interest in customer service

We wish we had followed the other poor reviews and never engaged with Everest Windows. Interested in decent windows for a more budget price so we did. They are super interested in you up to the deposit, put on a great act of professionality making you think they are a good company. Thereafter they drop the ball and all the design flaws, faults and abysmal customer service began. Their design missed out on basic fire safety regulations and a surprise cost was needed after. In short, they’re all charm until they have your money—then they’re terrible. Still chasing getting my refund which conveniently to them they hold for 28 days. They also share your details with 3rd parties and have had none stop calls, thanks for that little gem everest

So, Contacted Everest to get quote for front and back doors. No one showed for 2 appointments and no phone calls to say why. Third appointment went well except the configuration of the doors was incorrect on the resulting schedule of works. Still waiting to hear from somebody with a revised schedule of works and quote.

Meanwhile, I wanted to obtain 3 quotes before making a decision so I had contacted Anglian and Safestyle. Made an appointment with Anglian, but no one showed up. I called to find out why. Seems Everest, Anglian and Safestyle are all owned by a holding company and they share customer data. Further they will not provide more than 1 quote across the 3 companies. Not sure if that contravenes GDPR. Anyway, all three companies need to state explicitly on their website that customer data is shared and you can only obtain 1 quote from 1 of the 3 companies.

Update: 24hr response from Everest on Trustpilot. Contact details provided privately. Await their disposition.

we phoned everest 2 occasions to make appointments s a quote for some work we required by them. the first appointment they failed to turn up. the 2nd appointment that they made with us, they phoned a day before they were due to call to our home. a phone call just to say they dont have a person available on that date , so they cant make the appointment. needless to say we are no longer interested in having this company mess us around any more.

Edit for response: I am an indirect customer via Bromford Housing Association, as the works were arranged under their contract. I have provided Bromford’s details in the request for further information because I am the tenant affected by the installation but was not the contracting party, and therefore do not consider it necessary to provide additional personal contact details. Any verification queries can be directed via Bromford.

FENSA report pending, but preliminary confirmed non compliances. Like I said.

From my experience, the brands involved appear connected under the ASHI Group Limited umbrella, and multiple trading names were referenced or present during the installation works carried out on behalf of Bromford Housing. For this reason, I consider it reasonable to reference the wider group context when leaving feedback.
I am concerned about how situations like mine may impact other vulnerable tenants who may struggle to pursue resolution. I believe independent scrutiny, proper accountability, and improved engagement practices would benefit both customers and contractors moving forward.
In public responses across multiple profiles, representatives referenced Anglian Building Products as a shared department and described related brands as sister companies. Based on this, I considered it appropriate to reference the wider group context when leaving feedback.

Parked on my drive while doing a neighbours window install, I would've let them if they'd asked but decided to just help themselves, seems poor and unproffessional IMHO.

Jaswant was brilliant. Very accommodating on our needs and explained everything in great detail and made us feel very confident in the product.

Woudl highly recommend using him

My partner is having a nightmare with this company . Where do we go for help as he has a door that won’t open and they have made such a mess of internal decor and external rendering . Has anyone had any success with taking them to court ?
