Upfront cost — no obligation Potterton is one of Britain’s longest-established boiler brands, and their boilers are found throughout East London homes — from newer Assure and Performa models to older units still giving good service. Gas First repairs Potterton boilers of all ages. Our engineers know the brand’s common faults and error codes well, so we get to the cause quickly and restore your heating and hot water with minimum disruption.
Common Potterton faults and error codes
Potterton boilers display error codes when something is wrong. E1 typically indicates an ignition fault — the boiler is failing to light. E2 points to a fan or flue issue. Low water pressure is also common and often shows as a warning on the display. Older Potterton models can suffer from worn heat exchangers or failed diverter valves (loss of hot water while heating still works). We diagnose the root cause rather than just clearing the code.

Potterton models we repair
We work across the Potterton range, including the Assure (24, 30, 35 kW), Performa (24, 28, 33 kW), Gold series, and Titanium models. Potterton is a sister brand to Baxi — both are made by BDR Thermea — which means parts are widely available and we can usually source what’s needed quickly, keeping repair times short.

Older Potterton boilers
Many East London homes still have older Potterton models in service. Older boilers often develop familiar faults: worn pump bearings, failed thermocouples, or cracked heat exchangers. We can assess whether repair is worthwhile or whether the age and fault together point to replacement. We always give you a straight, honest picture so you can make the right decision for your home.

Frequently Asked Questions
What does E1 mean on a Potterton boiler?
E1 on most Potterton models indicates an ignition fault — the boiler is trying to light but cannot. This requires a Gas Safe engineer to diagnose. Causes include gas supply issues, faulty ignition electrodes, or a failed gas valve.
My Potterton boiler keeps losing pressure — what's wrong?
Repeated pressure loss points to a leak, a faulty expansion vessel, or a pressure relief valve discharging. It needs investigation to find the source rather than just topping up the pressure.
My heating works but I have no hot water — what's the cause?
On Potterton combi boilers, this is often a failed or stuck diverter valve. The boiler prioritises hot water over heating, so if the diverter fails the hot water circuit can be affected. It's usually a straightforward repair.
Is it worth repairing an old Potterton boiler?
Potterton boilers are reliable British-made units and often worth repairing. We'll give you an honest assessment based on the boiler's age and the cost of the fault.
Can you come out the same day?
We aim to attend the same day across East London, especially if you tell us the model and error code so we arrive ready.
