Tired of Engineers Who Quote One Thing, Charge Another, and Disappear When You Need Them?

You shouldn't have to chase a boiler quote like it's a favour.

You ring. No answer. You email. Nothing. You try again. Finally someone picks up — and then never shows up.That's not bad luck. That's the norm now.One homeowner put it plainly: "It's so hard to get a contractor. Ring, no answer. Email, no answer. Ring more times, finally get answer, never shows up and ghosts you."Another paid for a brand new Worcester Bosch, watched the installer pocket the money, promise the annual service — and disappear.

Three years later, the 10-year warranty was void. Gone. Because the service was never done.And British Gas?

"British Gas quoted me £6k when my boiler went down. I got a local guy to do it for £1,500. Like for like." They know exactly when you're desperate. They price accordingly.You're not being paranoid.

The residential heating industry really has turned into this.

You deserve a Gas Safe engineer who shows up when they say they will, quotes you honestly, and registers your warranty before they leave.

That's what we do. Every time.

We visit before we quote.

No photos, no guesswork, no showing up and discovering the gas pipe is the wrong size. We lift the floorboard, check the pipework, and confirm exactly what the job involves before we name a number.

We give you a written, itemised quote — VAT included.

Boiler brand, model, output, flue kit, system flush, magnetic filter, inhibitor, controls, warranty registration. Every component named. Every cost shown. The number on the quote is the number on the invoice.

We install the boiler and register the manufacturer warranty on the same day.

Before we leave, we hand you the Gas Safe certificate, the warranty documentation, and a service record card with our number on it. And we book the first annual service before we walk out the door — because that service is what keeps your 10-year warranty alive.

We are still answering the phone in year seven.

Not a call centre. Not a subcontractor. The same engineer who fitted your boiler.

What We Install — and What We Include as Standard

Every installation includes a system power flush, magnetic filter, inhibitor treatment, Gas Safe certificate, and manufacturer warranty registration. These are not optional extras — they are what a proper job looks like.

What Does a New Boiler Actually Cost? Here Is What You Should Expect to Pay.

Prices vary by boiler size, property type, and what the installation involves. Here is what a standard replacement costs — and what it includes.
Most straightforward combi boiler replacements in a 3-bedroom UK home fall between **£2,500 and £3,800 all-in**, including the boiler, installation, system flush, filter, flue, Gas Safe certificate, and manufacturer warranty registration. VAT is included in every price we quote — not added at the end.

British Gas and national companies typically quote £4,000–£5,500 for the same job. Online platforms quote lower — but they quote from photos, use subcontractors they have never met, and when something unexpected comes up, they leave. We have seen this happen to homeowners more than once.

If a quote looks very cheap, ask what is included. If it does not name the boiler model and list every component, the number is not a real quote — it is an opening bid.

We give you the full number before we start. It does not change on the day.

Questions You Should Ask Every Boiler Engineer — Including Us

We wrote this section because the best homeowners in this market are the ones who know exactly what to ask. Here are the questions that separate a trustworthy engineer from one who is not.

How do I know this person is Gas Safe registered and not unqualified?

Our Gas Safe number is [number]. You can verify it in under 30 seconds at gassafe.co.uk. We will also show you our card before we start any work.

Only if you ask us to do something additional that was not in the original scope. We have never added to a quote without the homeowner's explicit agreement first.

This is one of the most common complaints in this trade — and it is how expensive warranties get voided. We book the first annual service before we leave on installation day. It is in writing. We show up.

Boxt works when the job is straightforward. When it is not — wrong pipe size, flue reroute needed, older system with complications — they leave. We have done jobs that online installers walked away from. British Gas quoted one of our customers £5,000 for a job we did for £2,800.

It depends on your property and your household's hot water demand. We will tell you honestly at the survey stage — not what earns us more margin, but what suits your house.

Every Winter, Boilers Break on the Coldest Weekend of the Year

The homeowners who are sitting in a freezing house in January, ringing round and getting told the earliest available engineer is next Thursday, are the ones who knew their boiler was struggling and put off sorting it.

You don't know cold until you have to go several days without a boiler in winter. It is nothing like coming into a cold house because the heating hasn't been on all day.

Installation slots fill from October onward. Homeowners who book a survey now choose their install date on their own terms, in daylight hours, without a broken boiler forcing a rushed decision. Homeowners who wait until January join a queue — and pay whatever they are quoted, because they have no time to compare.

The survey is free. There is no obligation. It takes one visit to find out exactly what you are looking at and what it costs.

We visit. We assess the job. We give you a written, itemised quote with every cost shown inclusive of VAT. You decide what to do next.

The survey takes around 30–45 minutes. We check the boiler position, pipework, gas supply, and flue route before we quote — so the number we give you is the number you pay. We recommend the boiler that suits your property, not the one that suits our margin.

Most customers receive their written quote within 24 hours of the survey.
