Upfront cost — no obligation A new boiler is a big purchase, so it’s worth getting right — and worth honest advice on whether you need one. Gas First fits new and replacement boilers across Upminster and the RM14 postcode, from our Dagenham base — the village, Corbets Tey and Cranham. We start with a free, no-obligation survey, tell you honestly whether a repair or a replacement makes more sense, and give you a clear fixed price before any work begins.
When a boiler needs replacing in Upminster
Some faults can’t be economically repaired. A leaking heat exchanger is the classic example: it’s one of the most expensive parts in the boiler, and on a boiler that’s already ten years or more old, replacing it rarely makes financial sense — you’d spend heavily on an old unit that’s likely to develop the next fault soon after. When that’s the situation we explain it clearly, set out your replacement options and costs, and let you decide. The right replacement depends on your home — and in Upminster’s larger houses that often means a system boiler with a cylinder to serve several bathrooms, rather than a combi.
What's included in a Gas First installation
Our installations are done properly, not rushed. Every install includes a survey and fixed quote; supply and fitting of your new boiler; removal and safe disposal of the old one; a system flush to protect the new boiler; a magnetic filter; connection of controls and thermostat; all necessary pipework and flue work; registration of your manufacturer’s warranty; notification to Gas Safe and Building Control; and a full test and commission on completion. Most straightforward swaps are completed in a day, and we tell you the timescale upfront for bigger jobs. We leave the job clean and show you how everything works before we go.
Extended warranties up to 10 years, from a local team
A big advantage of a new boiler is the manufacturer’s warranty — and on selected brands we can register a long one. On selected Worcester Bosch, Vaillant, Ideal and Glow-worm models, warranties of up to 10 years are available, and as a Baxi Works accredited installer we can extend a Main boiler from 2 to 5 years at no extra cost. Keeping to an annual boiler service is usually a condition of that warranty, so we can look after that for you too. We’re Gas Safe registered (587401) and fully insured, and our Dagenham base is a short run out to RM14.

A recent boiler installation in Upminster
A customer in Upminster had an Ideal Logic boiler that had developed a leaking heat exchanger. As one of the most expensive parts to replace, and with the boiler already over ten years old, we were honest that repairing it wasn’t good value — the sensible move was replacement. We talked the customer through their options, and they decided to replace it. We fitted a new Worcester Greenstar boiler, flushed the system, commissioned it and registered the warranty — leaving them with a reliable, efficient boiler and a long manufacturer’s warranty behind it.

Frequently Asked Questions
How much does a new boiler cost in Upminster?
Installations start from our fixed 'from' price, and the final figure depends on the boiler and your property. We give you a clear fixed price after a free, no-obligation survey.
My heat exchanger is leaking — repair or replace?
A heat exchanger is one of the most expensive parts, so on a boiler over about ten years old replacement is usually better value than repair. We give you the honest numbers and let you decide.
I have a larger home with several bathrooms — combi or system boiler?
Larger Upminster homes with high hot water demand are often better suited to a system boiler with a cylinder. We advise the right choice at the free survey.
What warranty can I get?
On selected Worcester Bosch, Vaillant, Ideal and Glow-worm models, up to 10 years is available. We register it for you.
Which parts of Upminster do you cover?
All of RM14 — the village, Corbets Tey, Cranham and the surrounding roads.
Are you Gas Safe registered?
Yes — registration number 587401, fully insured.
