Upfront cost — no obligation A new boiler is a big purchase, so it’s worth getting right — and worth honest advice on whether you even need one. Gas First fits new and replacement boilers across Rainham and the RM13 postcode, from our nearby Dagenham base — Rainham village, South Hornchurch and Wennington. 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.
Repair or replace? Honest advice in Rainham
Not every boiler fault means a new boiler — but sometimes a repair simply isn’t worth it. When a boiler has multiple expensive faults or is old and inefficient, the cost of repair can approach the cost of a reliable new one, and you’re still left with an ageing unit. We’ll always tell you honestly where the line is: if a repair makes sense we’ll do it, and if replacement is the better long-term value we’ll explain why and let you decide. The right replacement depends on your home — a combi for smaller homes and flats with one bathroom, a system boiler with a cylinder for larger homes with higher hot water demand.

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, and a local team
As accredited installers for several manufacturers, we can register and often extend your boiler’s warranty. As a Baxi Works accredited installer, for example, we can extend a Main boiler’s warranty from 2 years to 5 at no extra cost, and up to 10 years is available on selected Vaillant, Worcester Bosch, Ideal and Glow-worm models. Our Dagenham base is close to RM13 for a faster, more personal service from survey to aftercare — and because keeping to an annual boiler service is a condition of most warranties, we can look after that for you too. We’re Gas Safe registered (587401) and fully insured.

A recent boiler installation in Rainham
A customer in Rainham called us out to a boiler that had failed. On inspection we found faults with both the gas valve and the PCB (the boiler’s main circuit board) — two significant parts. We gave the customer the honest choice: repair the faults, or replace the boiler. Because the combined repair cost on an already-ageing boiler wasn’t economically viable, the customer decided replacement made better sense. We fitted a new Main boiler, flushed the system, commissioned it and registered the warranty — leaving them with a reliable, efficient boiler and cover they can count on, rather than money spent propping up an old one.
Frequently Asked Questions
How much does a new boiler cost in Rainham?
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.
Should I repair or replace my boiler?
If a repair is worthwhile we'll do it. But when a boiler has multiple costly faults or is old and inefficient, replacement is often better value. We give you the honest numbers and let you decide.
How long does a boiler installation take?
Most straightforward swaps are completed in a day. Conversions or relocations can take two to three days, and we tell you the timescale when we quote.
What warranty do I get?
Your boiler's manufacturer warranty, which we register for you — and on selected brands we can extend it, for example a Main boiler from 2 to 5 years as a Baxi Works installer.
Which parts of Rainham do you cover?
All of RM13 — Rainham village, South Hornchurch, Wennington and the surrounding roads.
Are you Gas Safe registered?
Yes — registration number 587401, fully insured.
