Upfront cost — no obligation Alpha boilers are a common sight across East London, particularly in flats and smaller homes where their compact size and value pricing have made them popular. Gas First repairs Alpha boilers including the E-Tec, E-Tec Plus, InTec and CB ranges. Our engineers are familiar with the brand’s error code system and typical fault patterns, so we get to the cause efficiently and get your heating and hot water running again.
Common Alpha error codes
Alpha boilers use E-series error codes. E10 is the most frequent: it means low water pressure — the system pressure has dropped below the minimum and the boiler has shut off as a safety measure. Re-pressurising fixes it in the short term, but if it keeps happening there is a leak or a component fault causing the pressure loss. E3 points to a fan or flue fault. E40 indicates ignition failure. We diagnose the cause, not just clear the code.

Frequently Asked Questions
What does E10 mean on my Alpha boiler?
E10 means the boiler's water pressure is too low. You can re-pressurise via the filling loop, but if pressure keeps dropping there is a leak or component fault that needs proper diagnosis.
My Alpha boiler shows E40 — what's wrong?
E40 indicates an ignition fault: the boiler is trying to light but failing. This could be a gas supply issue, faulty ignition electrodes, or a failed gas valve. It needs a Gas Safe engineer.
What is E3 on an Alpha boiler?
E3 points to a fan or flue problem. The fan may have failed or there could be a flue blockage. Do not continue trying to run the boiler — call an engineer.
Can you repair Alpha boilers the same day?
We aim to attend the same day, especially if you give us the model and error code when you call so we can arrive with the likely parts.
My Alpha is in a rented flat — can you help?
Yes, we work with landlords and tenants across East London and can usually attend quickly to restore heating and hot water.
