Annual Boiler Service in London
A real annual boiler service is not a five-minute "look at it" — it’s a manufacturer-specification check that keeps your warranty valid, your boiler safe and your gas bill where it should be. Ilir’s service includes a full strip-down of the burner and heat exchanger, a clean of all combustion components, a full combustion analysis, gas pressure check, gas tightness test, condensate trap clean, and a proper safety check. You get a written certificate at the end, and Ilir flags anything that’s heading toward needing attention so you can plan rather than be surprised.
