If you smell gas, do not touch any electrical switches, do not light any flames, and open all windows and doors immediately. Turn off the gas supply at the meter using the emergency control valve — turn the handle so it sits across the pipe. Leave the property and call the National Gas Emergency Service on 0800 111 999 from outside. Do not re-enter until given the all-clear.

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.

A new combi boiler installation in Lisburn generally costs between £2,500 and £4,500, including the boiler unit and fitting. The final price depends on the boiler brand, the complexity of the installation, and whether any pipework modifications are needed. If you are switching from a conventional system to a combi, expect additional costs of £500 to £1,000 for removing the old tanks and cylinders.

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.
