Heat pumps for Gloucester — from city terraces to the Forest of Dean.
Gloucestershire is two counties in one: city and market-town homes on mains gas, and a huge swathe of Cotswold and Forest of Dean villages that never got it. Thermal Earth designs and installs air- and ground-source heat pumps for both — 4,000+ systems over 20+ years, with our own designers, drillers and installers.
If you're heating with oil or LPG out in the villages, you're exactly who a heat pump helps most.

Two kinds of Gloucestershire home, two starting points.
Gloucester's terraces and suburbs.
On-gas homes switch for lower carbon and steadier comfort. The design craft is urban: where the unit sits, what the neighbours hear, how the pipework routes, and whether your radiators can run at heat-pump temperatures — measured room by room.
The Cotswolds, Severn Vale and Forest of Dean.
Off the gas grid, oil and LPG money burns fast. This is classic heat-pump country: bigger plots for ground collectors, buildings we can survey properly, and savings that show up in the first winter's bills.
Air or ground — your property decides, not the postcode.
Both technologies earn their place in Gloucestershire. The survey settles which one fits your home. See how we design the complete system.
One outdoor unit, thoughtfully placed.
We position the unit for airflow, sound, looks and easy servicing — then design the radiators, hot water, electrics and controls around it as one system. For most city and town homes, this is the natural route.
Explore air sourceTrenches and boreholes, drilled by our own rigs.
With a decent garden, paddock or field — common from the Severn Vale to the Forest — the ground becomes your heat source. We check services, access and geology, size the collector to the house, and reinstate what we dig.
The outdoor unit is only the beginning.
Inside, the design carries on: hot-water cylinder, pipework, radiators and controls, all sized to work together at heat-pump temperatures.
Coming off a combi boiler? We plan where the cylinder lives before you commit. Keeping your radiators? We measure them first — many Gloucestershire homes keep most of what they have.

Designed for lower bills, looked after for years.
A well-designed heat pump can cut heating costs — most dramatically when it replaces oil or LPG in the villages. Our estimate starts from your property, not a generic percentage.
Electrics and DNO notification are handled by us as part of the job. Afterwards, annual servicing and Comfort Care monitoring keep the system doing what the design promised.

For apartments, schools, offices and housing developments, we compare individual systems, shared ground loops and central plant — designed around ownership, phasing, metering and long-term operation.

Most air-source installations are permitted development under MCS 020 conditions. Gloucester's conservation areas, listed buildings and Article 4 streets can need consent — we check the exact rules for your address and design the unit position and pipe route around them.
Grant help, handled with you.
You may qualify for the Boiler Upgrade Scheme — we handle the application, and finance can spread the rest.
Eligible air-to-water or ground-source heat pump installations receive £7,500. If your property has no mains gas connection and you are replacing oil or LPG heating, the grant is £9,000 for applications properly made from 21 July 2026 to 31 March 2027. We check eligibility for your home.
Things Gloucestershire homeowners ask us.
Straight answers first — the survey fills in the detail for your own house.
Will a heat pump work in an older Gloucester home?
Age isn't a pass-or-fail test. We measure heat loss room by room, check the radiators and hot water, and find a unit position that works — then you see the design before deciding.
Do I need planning permission?
Usually not — most installations are permitted development. Listed buildings, conservation areas and Article 4 streets can change that, and we check your exact address before work starts.
Can I keep my existing radiators?
Often, yes. We test each room's radiators at heat-pump temperatures — many homes keep most of them, some swap one or two.
Is ground source realistic here?
In the villages, very often — gardens and paddocks give the collector room, and our own rigs do the drilling. On tighter city plots, air source usually wins on practicality.
Will it lower my bills?
Replacing oil or LPG, usually yes — and noticeably. We'll show you the comparison for your own house, tariff and fuel rather than promising a universal percentage.
What happens after the free estimate?
We review your details, arrange a survey if it looks right, and come back with a full proposal — system, cost and grant route. No obligation at any step.

Gloucester city, the Cotswolds and the Forest.
Gloucester, Stroud, Cirencester, Tewkesbury, Newent, Dursley — and out west, Lydney, Coleford and Cinderford in the Forest of Dean, plus villages across the Cotswolds and Severn Vale.
Many of those villages have no mains gas, and those are the homes where a heat pump changes the bills most. For Cheltenham and the north Cotswolds, see our Cheltenham page — or see everywhere we work.
