Types of Boiler Services and Typical Costs
Every property has different heating needs, so we provide a range of boiler services with transparent pricing. Below is an overview of common services and what impacts overall cost (final pricing depends on boiler type, access, condition, and any additional work requested).
Annual Boiler Servicing
A full annual service includes core safety checks, inspection of key components, and testing to confirm safe operation and stable performance. It’s the best way to maintain efficiency and support manufacturer warranty requirements.
Typical starting price: from £95 + VAT
Boiler Repairs
Repairs cover common faults such as pressure loss, thermostat problems, leaks, ignition issues, and inconsistent heating. Accurate diagnostics helps reduce unnecessary part replacements.
Typical starting price: from £120 + VAT
Boiler Installations
We install energy-efficient systems (combi, system, or conventional) with a focus on correct sizing, safe fitting, and long-term reliability. Installation cost depends on property size, pipework, and system layout.
