What Reion checks on every boiler service
Visual and flue inspection
External check of the boiler casing, flue terminal, condensate pipe, and surrounding pipework for corrosion, damage, or signs of leakage before the unit is opened.
Internal clean and component check
Inspection and cleaning of the heat exchanger, burner, condensate trap, and ignition leads. The main heat exchanger is checked for scale and corrosion that reduces efficiency over time.
Safety device testing
The pressure relief valve, overheat thermostat, and gas valve are all tested to confirm they operate within safe limits. Any device that fails the test is flagged and replacement options discussed.
Flue gas combustion analysis
A combustion analyser measures CO₂, CO, and excess air levels in the flue gases. This is the only reliable method to confirm the boiler is burning safely and within manufacturer tolerances.
System pressure and flow check
The boiler is run through a full heating cycle. System pressure, flow temperature, and return temperature are checked to confirm the boiler is working at full efficiency.
Written service record issued on the day
Reion issues a signed service record on the day of each visit. This document serves as proof of annual maintenance for warranty purposes and is required by most manufacturers.

Trusted by homeowners and landlords across South London
Reion came out the same day to fix our boiler. Diagnosed the fault quickly, gave a clear price, and had it running within the hour. Brilliant service.
Really impressed. Called on a Sunday morning with no heating and Reion was with us by midday. Honest, professional, and didn't try to oversell anything. Will definitely use again.
Needed a gas safety certificate for my rental property at short notice. Reion arranged it for the following day and had the certificate issued same day. Highly recommend.
