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.

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.

A leaking boiler should always be taken seriously. While a small drip from a pressure relief valve may indicate a minor issue, water leaking from the boiler casing can damage internal electrics and create a safety hazard. Turn off the boiler and the water supply to it, place a container under the leak, and call a Gas Safe registered engineer. Never attempt to repair a boiler leak yourself.

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.

At minimum, a boiler engineer must hold a Gas Safe registration covering the specific appliance category — for example, CENWAT for central heating wet and boilers. Many engineers also hold ACS (Accredited Certification Scheme) qualifications. For oil boilers, look for OFTEC registration. Manufacturer-specific training from brands like Worcester Bosch, Vaillant or Baxi is a further indicator of expertise.

A standard annual boiler service takes 30 to 45 minutes. The engineer will inspect the boiler internals, check gas pressure and flow rate, carry out a flue gas analysis, and test all safety devices. You will receive a service record which you should keep as proof for your warranty. The engineer should also flag any parts showing early signs of wear.
