Smarter Heating and Energy Savings with Heat Pumps and Solar Panels

Mariel • August 21, 2025

Across the UK, rising energy prices have made many households look for better, long-term solutions to cut costs. At the same time, more people want to live sustainably and prepare their homes for the future. One of the smartest ways to achieve this is by combining air source heat pumps (ASHPs) with solar panels.

The Cost of Installation vs. Long-Term Savings

The upfront cost of renewable systems can seem high, but the long-term rewards are hard to ignore. In the UK, an air source heat pump typically costs between £7,000 and £12,000, while a solar panel system ranges from £5,000 to £8,000. A battery adds more, depending on its size and capacity.



Despite this, a well-insulated home with both systems can reduce annual energy bills by up to 50%. With energy prices unlikely to fall significantly, the payback period is often quicker than many expect. Over time, the savings cover the cost of installation while giving you stability and peace of mind.

Support from Government Schemes

To encourage greener heating, the UK government provides funding that makes these upgrades far more affordable.


  • The Boiler Upgrade Scheme (BUS) offers up to £7,500 towards the cost of an air source heat pump.
  • The ECO4 Scheme supports eligible households with energy efficiency improvements, including help with heat pump installation.


While solar panels are not directly subsidised, combining them with a subsidised heat pump can make the investment much more manageable. In some cases, households can also sell surplus electricity back to the grid, creating an extra income stream.

How Heat Pumps and Solar Panels Work Together

Air source heat pumps draw warmth from the air outside and use it to heat your home and water. They run on electricity and are much more efficient than a gas boiler.


Solar panels, meanwhile, capture energy from sunlight and convert it into electricity for your household.


When paired together, solar panels can supply the electricity needed to power your heat pump. This reduces reliance on the grid, cuts bills, and ensures your home uses renewable energy for both heating and electricity.

Why Combining Them Makes Sense

The benefits of installing both systems together are wide-ranging:


  • Lower running costs – Solar energy reduces the electricity you need from the grid.
  • Faster payback – The combined savings add up more quickly.
  • Greener living – Your household emissions will be reduced, helping meet UK net-zero goals.
  • Stability – Protection against rising energy prices offers financial security.
  • Property value – Homes with renewable energy systems are increasingly attractive to buyers.


Together, they create a future-proof energy solution that offers both financial and environmental benefits.

Do You Need a Battery?

Solar panels work best during daylight, but many households use more energy in the evenings and mornings. Without a battery, surplus solar electricity is exported back to the grid.


Installing a battery means you can store that extra energy and use it later, maximising efficiency and reducing grid dependence even further. While it adds to the initial cost, for households with higher energy use, it’s often a worthwhile upgrade.

Is Your Home Suitable?

This setup isn’t limited to large properties—many homes can benefit. The best results are achieved in houses that:


  1. Are well insulated to keep heat inside.
  2. Have suitable roof space with good sunlight exposure.
  3. Plan to remain in the property long-term to maximise savings.


Even smaller homes can take advantage of heat pumps and solar panels, as long as the system is correctly sized and installed. A professional survey can confirm if your home is a good match.

Air source heat pumps and solar panels are impressive technologies on their own, but together they provide one of the best ways to lower bills, reduce emissions, and gain energy security. The combination makes your home cheaper to run, greener, and more attractive to future buyers.

The Energy Company Obligation (ECO4) Scheme is a government initiative designed to promote energy efficiency in UK homes. By supporting households with funding for energy-saving improvements, the scheme plays a vital role in reducing energy bills and cutting carbon emissions. This blog explains who can benefit, what the scheme funds, and how to apply, helping you make the most of this opportunity to upgrade your home’s energy efficiency.

Home heating accounts for 38% of gas use in the UK, contributing to considerable CO2 emissions, with the average gas boiler emitting 2.2 tonnes of CO2 annually. An air source heat pump, powered by renewable electricity, offers a more sustainable alternative, which is why the government is promoting its adoption. The UK government aims to phase out gas boilers by 2035 as part of its plan to achieve net-zero emissions by 2050. To support this transition, grants are being offered to help households install air source heat pumps and other low-carbon heating solutions, encouraging homeowners to switch from their old gas and oil boilers to cleaner, greener options.

Various heat pump variants, such as air source, ground source, and hybrid systems, offer efficient and environmentally friendly heating options for your home, all while being cost-effective. Preparing your home for a heat pump involves several key considerations: Insulation and Energy Efficiency : Before installing a heat pump, assess your home's insulation and overall energy efficiency. Upgrading insulation and improving energy efficiency can significantly reduce energy costs and ensure optimal performance from your heat pump. Available Space: Determine if your property has enough space for the type of heat pump you're considering, whether it's an air source, ground source, or hybrid system. Different heat pump types require specific space considerations, so ensure your property meets these requirements. Planning Permissions: Check with your local authority to understand if your heat pump installation requires planning permission. Regulations can vary, so it's important to align your plans with local guidelines to avoid any legal issues. Radiators and Pipework: Evaluate your existing radiators and pipework to determine if they're compatible with a heat pump. Heat pumps can work with various heating systems, including radiators and underfloor heating. In some cases, minor adjustments or upgrades may be necessary for optimal compatibility. Maintenance and Servicing: Plan for regular maintenance and servicing of your heat pump to ensure it operates efficiently and maintains longevity. Access to qualified technicians for servicing and addressing any issues promptly is essential for optimal heat pump performance. By addressing these factors, you can better prepare your home for a heat pump installation, ensuring maximum efficiency and effectiveness of your heating system.

Heat pumps are required to display an energy label indicating their efficiency level, ranging from dark green (most efficient) to red (least efficient). Since September 26, 2015, all newly manufactured heat pumps must come with an EU product label. Additionally, the installer is responsible for providing a package label that showcases the efficiency based on various components within the heating system. Any heat pumps certified by the Microgeneration Certification Scheme must include a product label upon sale, and the installer must also provide a package label. Failure to have a product label may result in the heat pump being ineligible for Government grants. Air-source heat pumps are among the most efficient methods for heating homes, resulting in significantly lower running costs compared to conventional heating systems. According to the Energy Saving Trust, heating a home with gas costs around 4.6p per kWh, while standard electric heaters cost between 9 and 16p per kWh. A typical air source heat pump may run at approximately 4.7p per kWh, potentially dropping to 2.3p if utilizing Economy 7 electricity or switching to our GoElectric tariff.
