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.
Across Gloucestershire and Gloucestershire, winter solar output is modest, so our heat pump designs never rely on it for heating. Homes in Gloucestershire with existing panels can often have the heat pump set to heat water from their daytime output. For Gloucestershire households out during the day, a battery can carry daytime solar into the evening heating period.
Who it suits
- Homeowners planning a heat pump who want to add panels at the same time
- Homes with a roof facing anywhere from east through south to west, with little shading
- Households considering a battery to store daytime or cheaper overnight electricity
- Homes with existing solar PV that currently export much of their output
Grants and rules for heat pumps in England
Homes in Gloucestershire 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.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Heat pumps with solar panels and batteries questions
How much do solar panels and a battery cost with a heat pump?
Solar PV and batteries are quoted separately from the heat pump, because the price depends on your roof, the number of panels, scaffolding, the inverter and any battery size. We survey the roof and give a written quote for that part of the work. The heat pump itself is priced from its own guide ranges, shown on our prices page.
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.
Should I fit solar panels before or after a heat pump?
Either order works, but planning both together helps. Knowing the heat pump's electricity use helps size the panels and any battery, and the electrical work for both can be coordinated, including the consumer unit and any notification to the network operator. If you already have panels, the heat pump controls can be set to use their output for hot water.
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.
