With more UK homeowners switching to low carbon heating, heat pumps are becoming increasingly common across the South East. But one key question remains:
“How do you keep heat pump running costs as low as possible?”
The answer is simple: solar panels.
If you already have a heat pump – or you’re planning to install one – adding solar PV is one of the most effective ways to reduce electricity costs, improve efficiency and future proof your home.
Why Heat Pumps Increase Electricity Use
Heat pumps are highly efficient, but they run on electricity – not gas – and electricity is more expensive than gas. Air source heat pumps typically use 2-4 kWh of electricity to deliver 6-12kWh of heat. This efficiency is excellent – but still increases your reliance on grid electricity and with UK electricity prices remaining relatively high, running costs soon add up.
This is where solar becomes essential.
How Solar Panels Support Your Heat Pump
Solar panels generate free, renewable electricity during daylight hours – exactly when your home is active. By pairing solar with a heat pump, you can power your heating system with your own generated electricity, reducing how much energy you import from the grid. This can lower your overall heating costs significantly (and your electricity bill). In short: solar panels help fuel your heat pump for free.
Key Benefits of Adding Solar to a Heat Pump System
Lower running costs – heat pumps are efficient but electricity isn’t cheap. Solar panels directly offset that cost, making your system far more economical.
Faster return on investment – if you already have a heat pump, your electricity usage is higher – meaning you’ll use more of the solar energy you generate. This improves payback times.
Greater energy independence – you rely less on the grid, protecting yourself from future price rises.
Reduced carbon emissions – heat pumps are already low carbon. Powering them with solar makes your home even more environmentally friendly.
Ideal Setup for Heat Pump Homes
For homeowners in the South East, the most effective setup includes:
- A well sized solar PV system
- Optional battery storage to store surplus daytime energy
- Smart controls to optimise when your heat pump runs
This allows you to maximise self-consumption, rather than exporting energy back to the grid.
Planning a Heat Pump? Install Solar First (or at the Same Time)
If you’re considering a heat pump installation, it’s worth thinking ahead. Installing solar panels:
- Helps offset future electricity demand
- Makes your home more attractive for heat pump upgrades
- Reduces long term running costs from day one
Many homeowners across the South East are now designing their systems together for maximum efficiency.
Is Your Home Suitable?
Most homes are suitable for solar, but key factors include roof direction and available space and daylight exposure (minimal shading is ideal, mild shading can be overcome with power optimisers and a SolarEdge technology). Your household energy usage needs to be significant enough to outweigh the cost of solar – at SolarTherm UK we recommend solar to anyone paying over £50 per month on their electricity bill. If you already have a heat pump, your property is likely to be an excellent candidate for solar due to higher electricity demand.

Frequently Asked Questions
Do I need solar panels if I have a heat pump?
Not essential—but highly recommended. Solar significantly reduces running costs.
Will solar panels run my heat pump completely?
Not entirely, especially in winter—but they can cover a substantial portion of your usage annually.
Should I get battery storage as well?
If you have a heat pump, battery storage can increase how much of your solar energy you actually use.
Is solar still worth it without a heat pump?
Yes—but pairing it with a heat pump increases savings and efficiency.
When is the best time to install solar panels?
Before or alongside a heat pump installation is ideal—but adding solar afterwards is still very effective.
