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.

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.

Boiler repairs in Lancaster typically cost between £150 and £400, depending on the fault and the parts required. Common repairs like replacing a faulty diverter valve or fan motor sit at the lower end, while PCB (printed circuit board) replacements can push costs higher. A Gas Safe registered engineer will diagnose the fault and provide a fixed quote before starting any work.

A boiler that loses pressure gradually over weeks usually has a small leak somewhere in the system — often a radiator valve or a pipe joint. This is not an immediate emergency but needs investigating. If the pressure drops rapidly or the boiler is cutting out repeatedly, call an engineer promptly. You can repressurise the boiler using the filling loop as a temporary fix, but this does not solve the underlying problem.

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 Lancaster immediately and use electric heaters as a temporary measure.
