Hybrids appeal where a full heat pump is hard to do right now: a newer boiler with years of life left, a large or draughty house where a full system would need a very large unit and many radiator changes, or a combi home with no cylinder space, as some hybrids keep the combi for hot water. They can also be a step towards a full system later.
For Gwent homes with a boiler that is still fairly new, a hybrid lets a heat pump take on much of the heating now. Combi homes in Gwent with no space for a cylinder can look at a hybrid that keeps the combi for hot water. In Gwent, the outdoor unit of a hybrid needs the same airflow and siting care as any heat pump.
Who it suits
- Combi homes with no room for a cylinder
- Owners who want a stepping stone towards a full heat pump later
- Homes with a fairly new boiler the owner wants to keep using
- Large or hard-to-insulate homes where a full heat pump is difficult for now
Grants and rules for heat pumps in Wales
Homes in Gwent can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.

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.
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.
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.
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.
