Residential gas, heating and HIU services
Full-scope gas and heating support for homes, rented properties and residential developments. We service, maintain and certify boilers, HIUs and associated controls, so every property stays safe, efficient and fully compliant all year round.
The challenge
Every home needs heating it can rely on
Residents expect heating and hot water to work every day. Boilers and heat interface units need regular servicing, landlords need valid gas safety certificates, and when something fails residents want it fixed on the first visit.
Our engineers carry a wide range of common parts as van stock and are trained to diagnose and resolve issues with residents on the same visit, reducing disruption and the need for a return call-out.

For landlords
Letting a property? Know your gas safety duties
Landlords must make sure the gas appliances, fittings and flues in rented homes are safe. We carry out the annual gas safety check and provide the record you need.
Every 12 months: each gas appliance and flue needs a safety check by a Gas Safe registered engineer.
Within 28 days: existing tenants must be given a copy of the gas safety record after each check.
Before they move in: new tenants must be given a copy of the current record.
Keep records: each gas safety record must be kept for at least two years.
The check can be carried out up to two months before it is due without losing the original renewal date. Source: HSE guidance for landlords.

Heat interface units
HIU servicing and fault support
In many residential developments, each home takes its heating and hot water from a communal energy centre through a heat interface unit (HIU), rather than its own boiler.
We look after HIUs alongside the plant room that feeds them, so the whole system is maintained by one specialist contractor.
Inspection and servicing
Flushing
Temperature checks
