Upfront cost — no obligation Main boilers are manufactured by Baxi and are found in many East London homes, particularly in social housing and smaller flats where their affordability made them a popular choice. Gas First repairs Main boilers including the Combi and Eco Compact ranges. As a Baxi sister brand, Main boilers share components and fault patterns, and our engineers diagnose and repair them efficiently.
Common Main boiler faults
Main boilers share the Baxi fault-code system. E1 typically indicates an ignition fault — the boiler is trying to light but failing. E2 points to a fan or flue fault. Low water pressure is common and shows as a warning: re-pressurising may clear it in the short term, but if pressure keeps dropping there is a leak or component issue that needs finding. We diagnose the root cause so the problem does not return.
Main boiler models we repair
We work on the Main Combi 24 HE, 30 HE and 25 models, as well as the Eco Compact range. Because Main and Baxi are made by the same manufacturer (BDR Thermea), parts are widely available and interchangeable in many cases, making repairs straightforward and cost-effective. We can usually source parts the same day or next day.

Main boilers in rental properties
Main boilers are frequently found in East London rental properties. If you are a landlord with a Main boiler fault, we can attend quickly and carry out the repair. We also carry out landlord gas safety certificates (CP12) — if your boiler is due a repair and your annual inspection is coming up, we can often combine both visits to save you time.

Frequently Asked Questions
What does E1 mean on a Main boiler?
E1 typically indicates an ignition fault — the boiler is trying to light but failing. It needs a Gas Safe engineer to find the cause, which could be gas supply, ignition electrodes, or the gas valve.
My Main boiler keeps losing pressure — why?
Repeated pressure loss points to a system leak, a faulty expansion vessel, or a pressure relief valve that is discharging. Topping up pressure is not a fix — the cause needs finding.
Is a Main boiler the same as a Baxi?
Main is manufactured by BDR Thermea, the same group that makes Baxi. They share many components, which means parts are widely available and engineers who know Baxi know Main boilers well.
My Main boiler shows E2 — what does that mean?
E2 points to a fan or flue fault — either the fan has failed or there is a problem with the flue. Do not continue running the boiler; call an engineer.
Can you repair my Main boiler the same day?
We aim to attend the same day across East London.
