Upfront cost — no obligation A boiler service isn’t just a tick-box visit — it keeps your boiler running safely and efficiently, helps protect your manufacturer’s warranty, and catches small problems before they turn into breakdowns. Gas First carries out annual boiler services across East London — Bow, Stratford, Canary Wharf, East Ham, Dagenham, Barking, Romford, Rainham, Hornchurch, Elm Park, Upminster and Ilford — from our local Bow and Dagenham bases. Standard services start from £79, and we also offer a more thorough full strip-clean service for boilers that need it.
What's included in a standard boiler service
Our standard service is a full annual check to confirm your boiler is running safely and efficiently. We carry out a visual inspection of the boiler and its installation, looking for corrosion, leaks and signs of wear; remove the casing to inspect the key internal components; check the gas pressure and flow to make sure the boiler is burning correctly; and run a flue gas analysis to confirm safe, efficient combustion. We test the safety devices and controls, check and clear the condensate pipe if needed, and check the seals and general condition of the appliance. When we are done, everything is confirmed working and you get a service record for your files. We explain anything we find in plain English, and if a repair or a deeper clean is needed we tell you the cost before doing any extra work.

Standard service vs full strip-clean service
Not every boiler needs the same level of service, so we offer two options. A standard service (from £79) is the annual safety and efficiency check above — ideal for a boiler that has been regularly maintained and is running well. A full strip-clean service (priced by make and model) is a much more involved service for boilers that are older, haven’t been serviced in a while, or aren’t running as they should. We strip down the key components and typically replace the combustion chamber seals and the ignition or flame electrode, recharge the expansion vessel, and clean the heat exchanger and internal parts properly. Because the parts and labour depend on your boiler’s make and model, we price this individually and always confirm the cost before starting. Not sure which you need? Tell us your boiler’s age and how it is running, and we’ll advise honestly.

Why service your boiler every year?
Regular servicing pays for itself. It keeps the boiler running efficiently, which helps keep your gas bills down; it is usually a condition of keeping your manufacturer’s warranty valid; and it lets us catch small issues — a worn seal, low pressure or the early signs of a leak — before they turn into an expensive breakdown. The boiler pictured shows what neglect leads to: we were called to an Ideal boiler in Bow (E3) with a long-term leak that had never been fixed, causing heavy corrosion, and it had not been serviced. The owner told us it had been working only intermittently. We talked through the options honestly — repair the leak and the underlying fault, or replace the boiler given its age — and because the repair cost was significant and the boiler was over ten years old, they decided a new boiler was the better long-term investment. Caught early at an annual service, that leak would have been a simple fix. For landlords, we can also carry out a boiler service and your Landlord Gas Safety Certificate (CP12) in the same visit.
A recent boiler service in Rainham
We serviced a Vaillant boiler for a homeowner in Rainham (RM13) that hadn’t been serviced regularly. When we opened it up we found heavy sludge built up in the magnetic filter — a clear sign the system water hadn’t been maintained. We carried out a full service, cleaned out the magnetic filter and cleared the condensate, and got the boiler running cleanly and efficiently again. It is a good example of why an annual service is worth it: caught early, that sludge is a quick clean; left too long, it can damage the pump and heat exchanger and lead to a much bigger bill.
Frequently Asked Questions
How long does a boiler service take?
A standard boiler service usually takes around 30 to 45 minutes, depending on the age and condition of the boiler. A full strip-clean service takes longer because far more of the boiler is stripped down and cleaned.
How often should I service my boiler?
Once a year is recommended by manufacturers and is usually a condition of keeping your warranty valid. Annual servicing also keeps the boiler efficient and catches problems early.
What is the difference between a standard service and a full strip-clean service?
A standard service (from £79) is the annual safety and efficiency check. A full strip-clean is far more involved — we strip down and clean the key components and replace items such as the combustion chamber seals and electrode, and recharge the expansion vessel. It is priced by make and model.
Does a boiler service keep my warranty valid?
In most cases yes — manufacturers usually require an annual service by a Gas Safe registered engineer as a condition of the warranty. Keep your service records safe as proof.
Do you service all boiler brands?
Yes — Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, Viessmann, Potterton and many more.
How much does a boiler service cost?
A standard service starts from £79. A full strip-clean service is priced by your boiler's make and model, and we confirm the cost before any work.
Can you do a service and a CP12 together?
Yes. For landlords we can carry out a boiler service and a Landlord Gas Safety Certificate (CP12) in the same visit.
