Boiler Servicing

A standard service for a typical combi boiler usually takes around 45–90 minutes. Time varies with boiler make, age and how accessible components are — older or system boilers can take longer if extra checks or cleaning are needed.

The service includes combustion analysis, carbon monoxide checks, flue and ventilation inspection, gas pressure and flow tests, burner and heat-exchanger inspection, condensate-trap cleaning where applicable, controls and thermostat checks, plus a written service report highlighting any defects or recommendations.

No. A boiler service focuses on the appliance’s safety and performance; a Landlord Gas Safety Check (CP12) is a statutory check for rental properties. DS Plumbing & Heating offers both services — choose the landlord check if you rent out a property.
