Upfront cost — no obligation Worcester Bosch is among the most trusted boiler brands in the UK, fitted in countless East London homes. When one does develop a fault, Gas First can help — our engineers know the brand’s common issues and fault codes well. From a boiler that needs resetting to pressure loss, ignition faults or no hot water, we diagnose the real cause and repair it properly.
Common Worcester Bosch issues
Frequent Worcester Bosch problems include the boiler locking out and needing a reset, low pressure on the gauge, the boiler not firing for heating or hot water, and fault codes shown on Greenstar models. Some lock-outs clear with a simple reset, but a boiler that repeatedly locks out has an underlying fault that needs proper diagnosis rather than repeated resets.

How to reset a Worcester Bosch boiler
Most Worcester Bosch boilers have a reset button or dial — holding the reset for a few seconds often clears a one-off lock-out. If the boiler fires and runs normally afterwards, it may have been a transient issue. But if it locks out again, stop resetting and call an engineer: repeated lock-outs indicate a fault that will only get worse. See our Worcester Bosch reset guide for step-by-step help.

Frequently Asked Questions
How do I reset my Worcester Bosch boiler?
Most models have a reset button or dial — hold it for a few seconds. If the boiler runs normally afterwards it may have been a one-off; if it locks out again, call an engineer rather than repeatedly resetting.
Why does my Worcester Bosch keep losing pressure?
Repeated pressure loss usually points to a leak somewhere in the system or a faulty expansion vessel or pressure relief valve. It needs investigating to find the cause.
My Worcester Bosch boiler keeps locking out — what's wrong?
Repeated lock-outs signal an underlying fault, such as ignition, flue or sensor problems. Continuing to reset won't fix it — it needs diagnosis by a Gas Safe engineer.

Yes, we repair the Worcester Bosch Greenstar range and other models commonly fitted in East London.
Can you come out the same day?
We aim to attend the same day across East London. Giving us your model and the fault helps us arrive with the right parts.
