An annual boiler service keeps the system safe, efficient, and reliable. It reduces bills, catches faults early, and protects warranties. Always use a Gas Safe registered engineer and keep records for insurers or landlords. Expect a structured sequence of checks, cleaning, and recommissioning.

Safety and Performance Checks

The visit begins with a visual inspection of appliances, flue route, ventilation, and location. The engineer confirms gas pressure and flow, then uses a flue gas analyser to verify combustion and an unobstructed flue.

Electrical connections are tightened, safety devices tested, and seals and electrodes examined. Fans, pumps, and controls are checked for operation. Condensate traps and pipework are cleared and verified.

Cleaning, Adjustments, and Documentation

With power isolated, the case is removed and components cleaned – typically the burner, heat exchanger, and combustion chamber. The engineer reassembles the boiler, runs performance and leak checks, and records readings. Worn parts are identified, quotes provided, and recommendations made on water treatment or filter servicing.

If urgent issues arise, contact an emergency plumber Cheltenham or schedule follow up work with a reputable firm, such as hprservicesltd.com/emergency-plumber-cheltenham. A signed service sheet will be supplied.

Regular servicing supports safety, lowers breakdown risk, and keeps manufacturers’ guarantees valid. It can also reduce carbon monoxide risk and improve seasonal efficiency. Booking ahead before winter avoids busy periods and helps households plan budgets.

A well-maintained boiler heats faster, runs more quietly, and uses less energy, delivering comfort and confidence throughout the year.
