A hybrid heat pump is an air-to-water heat pump installed alongside an existing gas, LPG or oil boiler, with a controller that decides which one supplies heat at any moment. Typically the heat pump covers mild and moderate weather, and the boiler takes over or helps on the coldest days, or whenever it is cheaper to run on the prices entered into the controller.
For Warwickshire homes with a boiler that is still fairly new, a hybrid lets a heat pump take on much of the heating now. In Warwickshire, the outdoor unit of a hybrid needs the same airflow and siting care as any heat pump. A survey in Warwickshire can set a hybrid against a full heat pump for owners anywhere in Warwickshire.
Who it suits
- Large or hard-to-insulate homes where a full heat pump is difficult for now
- Owners who want a stepping stone towards a full heat pump later
- Homes with a fairly new boiler the owner wants to keep using
- Combi homes with no room for a cylinder
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
Hybrid heat pumps prices in Warwickshire
The ranges below are typical installed prices for homes in Warwickshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Warwickshire can need quite different radiators and pipework.
| System | Installed guide price |
|---|---|
| Hybrid heat pump alongside an existing boiler | £7,000–£11,000 |
Installed, inc VAT. Hybrid systems are not eligible for the Boiler Upgrade Scheme.

Hybrid heat pumps questions
Does a hybrid switch between heat sources automatically?
Yes. The hybrid controller follows rules set at commissioning: it might switch to the boiler below a chosen outdoor temperature, compare running costs using the prices you enter, or prioritise lower carbon. Some systems run both together in very cold weather. The installer sets these for your home and shows you how to adjust them when tariffs change.
Will a hybrid heat pump lower my bills?
It can reduce how much gas, LPG or oil you burn, but the effect depends on how the controller is set, your insulation, your tariff and fuel prices. You keep a boiler to service and, on mains gas, the standing charge. We do not promise a figure; instead the survey gives an estimate for your home comparing a hybrid with a full heat pump.
Is a hybrid a good step towards a full heat pump?
It can be, if the outdoor unit and pipework are sized with a future full system in mind. Later, once insulation has improved or radiators have been upgraded, the boiler can be removed and the system converted, provided the heat pump is large enough for the full load. Raise this at survey so the design leaves room to change.
Do I still need to service my boiler with a hybrid?
Yes. The boiler still needs its annual service, by a registered gas engineer for gas or LPG or an oil technician for oil, and the heat pump needs its own annual service, which is often a condition of the manufacturer's warranty. Two heat sources mean slightly more maintenance than either a boiler or a heat pump on its own.
