Why annual boiler servicing matters

Keeps your warranty valid Most boiler manufacturers require proof of annual servicing — skipping a service can void your warranty and leave you liable for repair costs.
Prevents winter breakdowns Most boiler faults are preventable — an annual service catches wear and minor issues before they cause a full breakdown in cold weather.
Maintains efficiency A serviced boiler runs more efficiently, which keeps gas consumption lower and your energy bills more predictable.
Carbon monoxide safety A Gas Safe engineer checks for combustion issues and flue integrity during every service — the only reliable way to detect dangerous CO risks early.
Legal requirement for landlords Landlords in England must have gas appliances serviced annually by a Gas Safe engineer and provide tenants with a copy of the certificate.

What a boiler service includes

01

Visual inspection

Reion inspects the boiler casing, flue, pipework connections, and surrounding area for visible signs of corrosion, leaks, or damage before opening the unit.

02

Internal checks and cleaning

The heat exchanger, burner, condensate trap, and key components are inspected and cleaned. Safety devices including the pressure relief valve are tested.

03

Flue gas analysis

A combustion analyser measures flue gas output to confirm the boiler is burning correctly and safely. Any deviation from manufacturer tolerances is noted.

04

System test and service record

The boiler is run through a full cycle and the heating system is checked for correct pressure and flow. A written service record is issued on the day.
