What our annual service covers

We follow manufacturers' checklists for Baxi, Vaillant and other common makes. Typical tasks include combustion analysis, burner and heat-exchanger inspection, flue checks, pressure and thermostat tests, seals and gasket inspection, and clearing condensate traps. Where required we fit a magnetic system filter or recommend a powerflush to remove sludge and restore flow.

Why the kit matters

Calibrated combustion analysers and manufacturer-approved test kits give precise readings so any tuning or safety action is based on evidence, not guesswork. That precision keeps emissions down, improves efficiency and helps secure extended warranties where applicable. If we find faults we provide a clear repair plan with photos and safety notes.

Frequently Asked Questions

A typical annual service takes 45–90 minutes depending on boiler type and access. We always allow time to complete combustion tests, clean key components and produce a written report. If we find repairs that need parts, we’ll explain timescales before any further work.
