Maintenance

A serviced system is a cheaper system.

Heating gets ignored until it stops. By then the cheap fix has usually become an expensive one.

Why it matters

An unserviced boiler quietly loses efficiency — a fouled heat exchanger, a blocked condensate trap or a system full of magnetite all make it burn more gas for the same heat. On a heat pump, a dirty coil or the wrong flow temperature can push running costs up sharply without anything appearing to be wrong. Small faults also tend to announce themselves in January rather than July.

What a service covers

Combustion analysis and gas rate on gas appliances, seals and safety devices checked, condensate and flue inspected, system pressure and expansion vessel charge set, magnetic filter cleaned and inhibitor levels tested. On heat pumps: coil condition, refrigerant performance, flow temperatures, defrost operation and control settings reviewed against how the property is actually being used.

Warranty and safety

Most manufacturer warranties are void without an annual service recorded by a registered engineer — a claim on a five or ten year warranty will be checked against your service history. Annual servicing is also how carbon monoxide risks and failing safety devices get caught. Landlords have a legal duty to hold a current Gas Safety Record for every gas appliance.

How we handle it

We keep a record of what was fitted, what was set and when it is next due, and get in touch when a service comes round so it doesn't fall off your list. Servicing is available whether or not we installed the system, and landlord certificates are issued the same day for letting agents and property managers.

Due a service, or not sure when yours was last done? Get in touch and we'll sort it.

How we prove it

Built to work. Proven to perform.

A heating system can look perfect and still perform poorly. That's why we don't just install and leave.

Every system is properly balanced, commissioned and tested on completion. Where it matters, we use thermal imaging to check heat distribution across circuits and emitters — giving us a clear picture of how the system is actually performing, not just what the gauges tell us.

You get the readings, certificates and a clear explanation of what was set, why it was set that way, and how your system is designed to perform.

Gas Safe Register

Every gas job notified and certificated.
