If you've been thinking about installing solar panels, battery storage or a heat pump but have been put off by the initial cost, there's some good news.

The government has recently launched the Warm Homes Loan Scheme, which could make it easier for homeowners to invest in renewable energy without having to cover the full cost upfront.

At Bison Eco, we know that the initial investment is often one of the biggest considerations for homeowners looking to make their properties more energy efficient.

This new scheme could give more people the opportunity to make those improvements.

Government Solar Panel Loans: What Is the Warm Homes Loan Scheme?

Launched on 27 October 2026, the Warm Homes Loan Scheme offers eligible homeowners access to low-interest or interest-free loans to help cover the cost of renewable energy installations.

Rather than paying for everything upfront, homeowners may be able to spread the cost over a longer period, depending on the finance provider.

The scheme covers several technologies, including:

Solar panels – loans up to £15,000
Battery storage – loans up to £15,000
Air source heat pumps – loans up to £20,000
Ground source heat pumps – loans up to £35,000

These are maximum supported loan amounts, and the finance available will depend on individual circumstances and the participating lender.

What Does This Mean for Homeowners in Bath, Salisbury and Wiltshire?

Across Bath, Bradford-on-Avon, Salisbury and the surrounding areas, there are plenty of homes that could benefit from renewable energy improvements.

Whether it's a modern family home, a countryside property or an older house undergoing renovation, the right system can make a difference to how much energy a household uses and where that energy comes from.

Of course, every property is different.

Some homes are well suited to solar panels, while others might benefit from adding battery storage or upgrading their heating system.

At Bison Eco, we look at what works for the individual property rather than taking a one-size-fits-all approach.

Could Solar Panels and Battery Storage Be Worth Considering?

Solar panels are a popular option for homeowners looking to generate their own electricity and reduce the amount they buy from the grid.

When combined with battery storage, they can be even more useful.

A battery allows you to store some of the electricity generated during the day and use it later, such as in the evening when the household is using more power.

This can help you make better use of the electricity your panels produce.

However, the right system will depend on your electricity usage, available roof space and how much energy you typically use throughout the day.

What About Heat Pumps?

Heat pumps are another option for homeowners looking to move away from traditional heating systems.

They work by extracting heat from the air or ground and using it to heat your home.

We've got a wide range of property styles across Bath, Somerset and Wiltshire, so it's important to make sure a heat pump is properly designed for the building.

Things like insulation, heat loss, radiator sizes and hot water requirements all need to be considered.

For homeowners thinking about replacing an older boiler or renovating a property, it's worth finding out whether a heat pump could be suitable.

Who Can Apply for the New Loans?

The scheme is available to eligible homeowners across the UK.

To qualify, you generally need to own the residential property where the work will take place, and the installation must meet the scheme requirements.

Applications are made through participating lenders, who carry out their own eligibility, credit and affordability checks.

Some lenders may offer interest-free loans, while others provide reduced interest rates.

It's worth comparing the options carefully, including the total amount repayable.

You can find further information on the official GOV.UK website.

Considering Renewable Energy for Your Home?

If you're based in Bath, Bradford-on-Avon, Salisbury, Trowbridge, Frome or the surrounding Wiltshire and Somerset areas, and you're considering solar panels, battery storage or a heat pump, we're happy to talk through the options.

At Bison Eco, we believe in finding the right solution for each property, taking into account your energy needs, budget and long-term plans.

The new government-backed loan scheme may make these improvements more accessible, but it's still important to understand what will work best for your home before making a decision.
