We design the heat pump first, from the room-by-room heat loss, and then look at how solar and storage could work with it. PV panels and batteries are quoted separately from the heat pump, after a roof survey, and the controls are set so the heat pump makes use of solar generation when it is available. See heat pump controls and tariffs for how timing and tariffs fit in.
Homes in Herefordshire with existing panels can often have the heat pump set to heat water from their daytime output. Scaffolding access for solar in Herefordshire is checked at the survey, including terraced streets with shared passages. For Herefordshire households out during the day, a battery can carry daytime solar into the evening heating period.
Who it suits
- Homes with existing solar PV that currently export much of their output
- Homes with a roof facing anywhere from east through south to west, with little shading
- Homeowners planning a heat pump who want to add panels at the same time
- Households at home during the day or with flexible hot water timing
Grants and rules for heat pumps in England
Homes in Herefordshire can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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.

Heat pumps with solar panels and batteries questions
Can solar panels run my heat pump in winter?
Only partly. In midwinter, solar panels typically generate a small fraction of their summer output, and the shortest days coincide with the highest heating demand. Panels may help on bright winter afternoons, but most winter heating will run on grid electricity or a battery charged from a cheaper overnight tariff. Solar contributes most to hot water from spring to autumn.
Is a solar diverter useful with a heat pump?
It can be, but less so than with a gas boiler. A diverter heats water through the immersion heater, which turns one unit of electricity into one unit of heat, while a heat pump typically makes around three. Scheduling the heat pump to heat water at midday usually uses solar more efficiently, with a diverter adding top-ups on very sunny days.
Can my roof take solar panels?
Most pitched roofs in sound condition can take solar panels, but every roof needs checking. The survey looks at orientation, pitch, shading, roof covering and structure, plus access for scaffolding. Flat roofs can use angled mounting frames. The survey also checks where the inverter and any battery would go and how cables would reach your consumer unit.
Do I need a battery to benefit from solar with a heat pump?
No. Without a battery you can still use solar generation directly by timing hot water heating for the middle of the day. A battery adds flexibility by storing surplus for the evening, or by charging from a cheaper overnight tariff in winter. Whether it suits you depends on how much you would otherwise export and on your tariff.
