Heating controls and smart thermostats
Good controls are one of the cheapest ways to add EPC points — a programmer, a room thermostat and thermostatic radiator valves let a home heat only what it needs, when it needs it.
What it is
A full set of controls for a wet heating system: a programmer or timer, a room thermostat, and thermostatic radiator valves on the radiators, optionally upgraded to a smart thermostat with app control and zoning. Together they stop the home over-heating and heating empty rooms.
Why it matters for 2030
The EPC gives credit for a properly controlled heating system, and controls are among the lowest-cost points on the whole plan. They also cut a tenant's bills immediately, which helps lettability while energy costs stay high.
Which homes suit it
Any property with a wet central-heating system that lacks a room thermostat, a programmer or thermostatic radiator valves — common in older rented houses. Smart thermostats suit homes where the tenant wants app control or where zoning a larger house saves money.
Grants that apply
Heating controls are an eligible measure under the Warm Homes: Local Grant and ECO4 when fitted alongside other work, and are zero-rated for VAT until 31 March 2027 as part of an energy-efficiency upgrade.
How we do it
We assess the existing system, fit the missing controls to current standards, and record them for the EPC — usually a quick, low-disruption visit done alongside the rest of the plan.
Common questions
Do better controls really change the EPC?
Yes, the assessment specifically credits a programmer, room thermostat and thermostatic radiator valves, so adding what is missing is a cheap way to gain points.
Do I need a smart thermostat?
Not for the EPC — standard controls score the points; a smart thermostat mainly adds convenience and zoning for the tenant.
Will it disrupt the tenant?
No, it is usually a few hours with the heating briefly off.
Can you fit controls without replacing the boiler?
Yes, the controls are fitted to the existing system.
