What's Included in Our Boiler Service
Our service follows Gas Safe standards and manufacturer requirements. Every check is performed systematically — nothing is skipped, nothing is rushed.
Combustion Analysis
Using a calibrated flue gas analyser, we measure CO, CO₂, and O₂ levels to verify safe and efficient combustion. Results are recorded and compared against manufacturer baselines.
Gas Pressure & Flow Verification
We check both static and dynamic gas pressure at the meter and at the boiler, ensuring the supply meets the appliance's rated input requirements.
Heat Exchanger Inspection
Visual and functional inspection of the primary heat exchanger for signs of scaling, corrosion, or blockage. On Viessmann models, this includes checking the stainless steel Inox-Radial; on Vaillant, the aluminium/silicon alloy exchanger.
Burner & Ignition System
Inspection of the burner plate, ignition electrode, and flame sensing electrode. Cleaning or replacement as needed to ensure reliable ignition and stable flame detection.
Flue & Ventilation Check
Visual inspection of the entire flue run for integrity, correct gradient, and adequate terminal clearances. Ventilation openings verified against current Building Regulations.
Safety Device Testing
All safety interlocks are tested — overheat thermostat, pressure relief valve, flame supervision device, and air pressure switch (on fan-flued appliances).
Controls & Thermostat Calibration
Verification that room thermostats, programmers, and motorised valves are operating correctly and responding accurately to temperature demands.
Condensate System Inspection
The condensate trap, drain pipe, and external termination are checked for blockages — particularly important before winter, when frozen condensate pipes are a common cause of boiler lockout.
System Pressure & Expansion Vessel
System pressure is checked and adjusted. The expansion vessel pre-charge is verified with a tyre gauge — an often-overlooked step that prevents pressure fluctuations and PRV discharge.
Gas Safe Certificate & Benchmark
Every service concludes with a Gas Safe service record and Benchmark logbook completion — both essential for warranty compliance and property records.
Why Annual Servicing Matters
Regular servicing isn't a luxury or an upsell — it's a legal recommendation for gas safety, a warranty requirement, and the most cost-effective form of boiler maintenance.
Safety
A boiler combusting gas inside your home carries inherent risk. Annual checks verify that combustion is complete, flue gases are safely exhausted, and safety devices are functioning. This isn't theoretical — we regularly identify issues during routine services that homeowners had no idea existed.
Warranty Compliance
Every major boiler manufacturer — Viessmann, Vaillant, Worcester Bosch, Baxi — requires annual servicing to maintain warranty cover. A missed service, even on an otherwise well-maintained boiler, can void your warranty entirely. The service record in your Benchmark logbook is your proof.
Efficiency & Running Costs
A well-serviced boiler maintains its rated efficiency. A neglected one doesn't. Deposits on the heat exchanger, misaligned burner settings, or incorrect gas pressure all reduce efficiency gradually — so slowly you won't notice on any single bill, but the cumulative cost over a year is significant.
Early Problem Detection
Components wear gradually. A flame electrode that's deteriorating will still work today but fail on the coldest night of the year. Annual servicing catches these patterns — replacing a £30 part during a calm Tuesday appointment rather than an emergency callout on a freezing Saturday evening.
Gas Safe Certified Service
By law, only Gas Safe registered engineers may work on gas appliances in the UK. This isn't optional — it's a legal requirement that protects you, your family, and your property.
Legal Compliance
Gas Safe registration is the only legal qualification for gas work in the UK. Our registration (#594276) is verifiable on the Gas Safe Register.
Insurance Validity
Home insurance policies require that gas work is carried out by a Gas Safe registered engineer. Non-compliant work can invalidate your cover.
Service Documentation
Every service produces a Gas Safe record and updated Benchmark logbook — your proof of compliance for warranty claims and property records.
Specialist Training
Beyond Gas Safe, our engineer holds Viessmann Registered Installer and Vaillant Platinum certifications — manufacturer-level expertise for premium brands.
