in Nuneaton & Warwickshire
Keep your boiler running safely and efficiently. A comprehensive annual service maintains your warranty, catches problems early, and prevents expensive winter breakdowns.
Service Overview
What You Need to Know
What Is This Service?
A comprehensive boiler service includes a full safety inspection, flue gas analysis, pressure checks, internal component cleaning, and efficiency testing. We issue a written service record and flag any concerns before they become problems.
Who Is It For?
Every homeowner with a gas boiler. It's essential if your boiler is under warranty — most manufacturers require annual servicing to keep the warranty valid. Landlords also need annual services for compliance.
When Do You Need It?
Once a year, ideally before winter. If your boiler hasn't been serviced in over 12 months, book one now — small issues caught early save hundreds in emergency repairs later.
Why Use a Professional?
Regular servicing prevents breakdowns, maintains efficiency, keeps your warranty valid, and ensures safe operation. It's the single most effective thing you can do to protect your heating system.
Don't Ignore the Signs
What Happens Without Regular Servicing?
- !Warranty voided — most boiler manufacturers require documented annual servicing. Miss one and your warranty could be completely invalid.
- !Reduced efficiency — a neglected boiler loses 10-15% efficiency over time, adding £100-200 per year to your gas bills without you realising.
- !Unexpected breakdowns — 80% of emergency boiler call-outs involve faults that would have been caught during a routine service.
- !Carbon monoxide risk — servicing includes critical combustion safety checks that detect dangerous gas leaks early.
- !Shortened lifespan — a well-maintained boiler lasts 12-15 years. Without servicing, expect 8-10 years and declining performance throughout.

In Detail
What's Included in a Boiler Service?
Our boiler service follows a comprehensive checklist that meets or exceeds every manufacturer's requirements. We begin with a thorough visual inspection of the boiler, flue system, and surrounding pipework to check for damage, corrosion, or unsafe conditions.
Internally, we inspect and clean key components including the burner assembly, heat exchanger, electrodes, spark generators, ignition leads, and gaskets. We check the expansion vessel pressure and recharge if necessary, and verify system pressure is within the correct operating range.
Our flue gas analysis uses calibrated digital equipment to measure carbon monoxide, carbon dioxide, and flue gas temperature. These readings confirm the boiler is burning gas safely and efficiently. If readings fall outside safe tolerances, we adjust the gas valve or recommend further investigation.
We also check all safety devices including the overheat thermostat, pressure relief valve, gas valve operation, and flame supervision device. The condensate trap and drain are inspected and cleaned to prevent the winter blockages that cause so many emergency call-outs across Nuneaton and Coventry.
At the end of the service, we issue a written record detailing all checks performed, gas analyser readings, and any recommendations. This document is essential for maintaining your warranty and provides evidence of ongoing maintenance for insurance purposes. We service all brands across Nuneaton, Bedworth, Coventry, Warwick, Tamworth, and surrounding areas.
