Heat Pump Installers in Bristol

Thermal Earth provides heat pump installation services across Bristol and the wider South West. As one of the UK’s most experienced heat pump companies with over 3,500 installations, we bring the same expertise that has made us Wales’s leading installer to homes and businesses in the Bristol area.

Bristol’s commitment to becoming carbon neutral by 2030 has made it one of the most forward-thinking cities in the UK for renewable heating. Whether you live in a Georgian townhouse in Clifton or a modern home in Bradley Stoke, we can design a heat pump system that fits your property.

Heat Pump Options for Bristol Homes

Air source heat pumps are the most popular choice for Bristol’s urban and suburban properties. They require minimal outdoor space — just enough room for the external unit — and modern systems like the MasterTherm BoxAir Inverter operate quietly enough for terraced streets.

Ground source heat pumps are ideal for larger Bristol properties with garden space or for new-build developments. Our in-house borehole drilling team can install vertical ground collectors with minimal disruption, even on constrained sites.

We also install solar PV and battery storage systems alongside heat pumps, allowing Bristol homeowners to generate their own electricity and reduce running costs further.

Bristol Heat Pump Costs and the £7,500 Grant

Bristol homeowners are eligible for the £7,500 Boiler Upgrade Scheme grant when replacing a fossil fuel heating system with a heat pump. This grant is deducted directly from your installation cost and has been extended to 2030.

  • Ground source heat pump: £10,500 to £37,500 (after £7,500 grant)

As an MCS certified installer, we handle the full grant application. Finance options are available to spread the cost.

Frequently Asked Questions

How much does a heat pump cost in Bristol?

A typical air source heat pump installation in Bristol costs £8,000 to £18,000, while ground source systems with boreholes range from £24,000 to £45,000. After the £7,500 BUS grant, costs start from around £500 for a well-suited property. We offer flexible finance to spread the remaining cost.

Do I need planning permission for a heat pump in Bristol?

Most air source heat pump installations are permitted development in Bristol and do not require planning permission. There are noise limits and placement rules (1 metre from the boundary), but we design all installations to comply. Listed buildings and conservation areas in central Bristol may need consent — we check this during your site assessment.

Can I keep my existing radiators?

Often, yes. Heat pumps run at lower temperatures than gas boilers, so we assess each radiator during our survey. Many existing radiators work fine, especially larger ones. Some homes benefit from upgrading a few key radiators for better comfort at lower flow temperatures. A full replacement is rarely needed.

What is the Boiler Upgrade Scheme grant?

The BUS grant provides £7,500 towards the cost of a heat pump for any homeowner in England replacing a fossil fuel heating system. There is no income test. The scheme has been extended to 2030 with increasing annual budgets. As an MCS certified installer, we handle the full application — the grant is deducted from your invoice, so you never pay the full price.

How long does installation take?

Air source heat pumps are typically installed in 2–3 days. Ground source installations take 3–5 days for indoor works plus 1–3 days for borehole drilling. We schedule Bristol installations efficiently and take care to minimise disruption to your property and neighbours.

Will a heat pump heat my home as well as a gas boiler?

Yes. A properly designed heat pump system heats your home just as effectively as a gas boiler. The difference is that heat pumps deliver heat at a lower, steadier temperature rather than short bursts of high heat. Many homeowners find this more comfortable — the temperature stays consistent throughout the day. Paired with underfloor heating, the comfort is exceptional.
