Short answer
In the UK, all boiler and gas appliance work must be conducted by a Gas Safe registered engineer to ensure safety and compliance. Whether you face a lockout, no heating, or low pressure, understanding the fault code and the status of your heating or hot water can guide the process.
Smell of gas: leave the house and call the emergency gas number. A boiler that will not fire in winter is urgent, not DIY.
Boiler and gas appliance work in the UK must be done by a Gas Safe registered engineer. This is not ordinary plumbing.

Questions
What should I do if my boiler shows a fault code?
First, note the fault code as it can help diagnose the problem. Then, contact a Gas Safe registered engineer to investigate and resolve the issue safely.
Can I repair my boiler myself?
It is strongly advised not to attempt any repairs on your boiler. Gas appliances should only be handled by qualified professionals to ensure safety and compliance with regulations.
