It is worth being clear about the seasons. Solar panels generate most from spring to early autumn, when a heat pump is mainly heating hot water. In December and January, when heating demand peaks, a typical roof produces only a small fraction of its summer output and covers little of the heat pump's needs. The strongest fit is daytime hot water heating for much of the year, with a battery or a time-of-use tariff helping in winter.
Homes in Lincolnshire with existing panels can often have the heat pump set to heat water from their daytime output. Scaffolding access for solar in Lincolnshire is checked at the survey, including terraced streets with shared passages. We plan heat pump and solar electrics together for Lincolnshire homes so the consumer unit is upgraded only once.
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
- Households at home during the day or with flexible hot water timing
- Households considering a battery to store daytime or cheaper overnight electricity
Grants and rules for heat pumps in England
Homes in Lincolnshire 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.
Prices
Solar panels and batteries are quoted separately after a roof survey. For heat pump system prices see the guide prices.

Heat pumps with solar panels and batteries questions
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.
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.
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.
