The time required depends on the fault, the boiler model, access and whether replacement parts are available. A straightforward repair may take one to two hours, while complex faults can take longer. The engineer will explain the expected timescale after diagnosis.
Not every boiler fault requires an emergency visit. However, urgent assistance may be appropriate where there is no heating or hot water during cold weather, a major leak, a risk of damage, or vulnerable people in the property. Any suspected gas or carbon monoxide issue must be treated as a gas emergency.
Common warning signs include loss of heating or hot water, pressure that is too high or too low, visible leaks, repeated shutdowns, unusual loud noises, a failed pilot light, poor radiator performance, error codes or a carbon monoxide alarm being activated.
Turn the boiler off if it is leaking, making unusual noises or appears unsafe. Avoid repeatedly resetting it or removing the boiler casing. Keep the area accessible, locate the user manual and service records, and tell the engineer about any error code displayed. Follow the gas-emergency guidance below if you smell gas or suspect carbon monoxide.
You may check the power supply, thermostat setting, system pressure and any error code, using only the manufacturer's instructions. You can try a single reset if the manual says it is safe. Do not open the boiler casing or attempt gas work yourself. Call a qualified engineer if the fault remains.
Replacement may be worth considering when the boiler is beyond economical repair, repeatedly breaks down, has obsolete parts or is no longer efficient. An engineer should assess the system and explain the options before any decision is made.
Gas or Carbon Monoxide Emergency
If you smell gas or suspect carbon monoxide, do not operate the boiler or electrical switches. Do not smoke or use a naked flame. Open doors and windows, turn off the gas at the meter only if it is safe to do so, and call the National Gas Emergency Service immediately on 0800 111 999. Leave the property and seek urgent medical help if anyone feels unwell.
The National Gas Emergency Service is open 24 hours a day, 365 days a year and operates throughout Great Britain.
