Warning signs include a yellow or orange boiler flame instead of blue, dark staining around the boiler, increased condensation on windows, and a pilot light that frequently goes out. Symptoms of carbon monoxide exposure include headaches, dizziness, nausea and confusion. If you suspect a carbon monoxide leak, open windows, leave the property immediately and call the Gas Emergency Service on 0800 111 999. Fit a CO alarm near your boiler — they cost under £20 and save lives.

Yes — most Gas Safe registered boiler engineers also handle radiator repairs, replacements, and balancing. Common radiator issues include cold spots (usually trapped air), leaking valves, and radiators that do not heat up due to sludge buildup. Radiator repairs typically cost £60 to £150, while fitting a new radiator including the unit costs £150 to £350.

Yes — an annual boiler service is essential for safety, efficiency, and warranty compliance. A service checks for carbon monoxide leaks, verifies the flue is clear, and ensures all components are working safely. Most boiler manufacturers require an annual service to maintain your warranty, so missing one could void your cover entirely. A well-serviced boiler also uses less gas, saving you money.

CORGI was the old gas safety registration body in the UK, replaced by the Gas Safe Register in 2009. Any engineer still claiming to be CORGI registered is either out of date or misleading you. The Gas Safe Register is now the only legally recognised body for gas work in the UK. Always check the Gas Safe Register website to verify your engineer's credentials.

Check the obvious things first: is the thermostat set correctly, is the timer on, and has the boiler pressure dropped below 1 bar? If the pressure is low, you can repressurise it yourself using the filling loop — your boiler manual will show you how. If none of these fix the problem, call a Gas Safe registered boiler engineer in Lisburn immediately and use electric heaters as a temporary measure.
