It is important to be clear about funding. In England and Wales, hybrid systems are not eligible for the Boiler Upgrade Scheme, which requires the heat pump to meet the home's full heating and hot water needs. You also keep a fossil-fuel boiler, its servicing and, on mains gas, the standing charge. We set out both options at survey so you can compare a hybrid with a full heat pump fairly.
Larger, older houses in Greater London that would need a very big heat pump may suit a hybrid while insulation is improved. Combi homes in Greater London with no space for a cylinder can look at a hybrid that keeps the combi for hot water. A survey in Greater London can set a hybrid against a full heat pump for owners anywhere in Greater London.
Who it suits
- Homes with a fairly new boiler the owner wants to keep using
- Owners who want a stepping stone towards a full heat pump later
- Large or hard-to-insulate homes where a full heat pump is difficult for now
- 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 questions
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.
Can I get the Boiler Upgrade Scheme grant for a hybrid heat pump?
No. In England and Wales hybrid systems are not eligible for the Boiler Upgrade Scheme, because the scheme requires the heat pump to meet the home's full heating and hot water needs on its own. If a grant matters to your budget, a full air-to-water heat pump is the option that can qualify. In Scotland and Northern Ireland we check at survey what, if any, funding applies.
Can a hybrid work with my combi boiler?
Yes, some hybrids are designed to work with a combi, with the heat pump heating the radiators and the combi continuing to provide hot water on demand. That avoids finding space for a cylinder, which is one of the main reasons people choose a hybrid. Other hybrid designs use a cylinder heated by the heat pump, with the boiler as backup.
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.
