Up to £9,000 off your installation

The government BUS grant covers a substantial chunk of your GSHP installation cost. As MCS installers we apply on your behalf — no paperwork for you.

Oil & LPG homes

£9,000

Increased from £7,500 on 21 April 2026. Designed for rural off-gas-grid homes — typically the highest-benefit GSHP switch.

Applicable to existing oil, LPG or direct-electric heating.

Mains gas homes

£7,500

For properties currently heated by mains gas looking to decarbonise.

Eligibility same for all fuel types — we handle the application.

BUS grant applications handled by us. Timeline: 2–4 weeks approval, 6-month installation window. Scheme funded to March 2028.

Running costs — compared

Indicative annual heating costs for a typical 3-bedroom rural home using around 18,000 kWh of heat per year (approximately 2,500 litres of oil equivalent). Actual savings depend on home size, insulation and tariff.

Heating fuelAnnual cost
Oil£2,100–2,800
LPG£2,300–3,100
Mains gas£1,200–1,700
Direct electric£3,500–5,000
Ground source heat pumpRECOMMENDED£800–1,100

Figures indicative, based on published UK price caps April 2026 and typical COP 3.8 for a well-designed GSHP. Your actual costs depend on home insulation, system size, and tariff — request a written estimate for your property for specific numbers.

We drill. We install. We maintain.
In-house teams, end-to-end.

Most of our GSHP competitors are renewable-energy resellers who outsource the drilling to specialist contractors. That works, but it means multiple contracts, multiple points of contact, and nobody owning the whole system.

We're different. We started as a drilling company 20+ years ago and built our GSHP installation team on top of that. When you work with us you get one team accountable for every part of the system — from the geology to the commissioning.

We own our drilling rigs

Compact rigs that fit through 5ft gaps. We control the schedule.

In-house design team

Qualified engineers size your system to your property, not to a stock catalogue.

Dedicated servicing team

Annual check-ups and rapid response from people who installed the system.

Three GSHP system types — one that's right for you

We design every system from scratch based on your geology, property and heating demand. Most domestic installations use closed-loop; some sites benefit from open-loop or river source.

Closed-loop

Vertical boreholes with sealed probes circulate a heat-transfer fluid through the ground. The most common system type, suitable for most sites. Probes typically go 100–200m deep.

Best for: most residential and commercial sites with limited garden space

Closed-loop details →

Open-loop

Water is abstracted from a borehole, passed through a heat exchanger, then returned to the ground via a second borehole. Can be significantly more efficient than closed-loop systems.

Best for: larger commercial projects with suitable aquifer conditions

Open-loop details →

River source

Water is abstracted from a river, canal or lake, filtered and passed through a heat exchanger before being returned downstream. Ideal for sites near watercourses.

Best for: sites close to rivers, canals or lakes with EA licensing

GSHP questions, answered

The questions we hear most often. Don't see yours? Get in touch — we'll answer before you quote.

How much does a ground source heat pump cost?
A typical domestic GSHP installation ranges from £25,000 to £45,000 depending on system size, borehole depth, geology and distribution system. With the BUS grant (£7,500 for mains-gas homes or £9,000 for oil & LPG homes), net installed cost is significantly lower. We provide free, written estimates after a site assessment.
Is my home suitable for a ground source heat pump?
Most homes with garden or paddock space for boreholes are suitable, including period properties, new builds and listed buildings. The key factors are available outdoor space, underfloor heating or correctly-sized radiators, and reasonable insulation. Send us your postcode and we'll do a desktop feasibility assessment before quoting.
What's the BUS grant and do I qualify?
The Boiler Upgrade Scheme is a government grant for replacing fossil-fuel heating with a heat pump. From 21 April 2026, the grant is £7,500 for homes currently heated by mains gas and £9,000 for homes heated by oil or LPG. As MCS-certified installers we apply on your behalf — the grant is deducted from your installation cost, not reclaimed later.
How long does installation take?
From first site visit to commissioned system is typically 8–14 weeks. Borehole drilling takes 2–4 days. Plant room installation and connection to your heating system takes another 1–2 weeks. BUS grant approval runs in parallel (2–4 weeks).
How disruptive is the drilling?
Less than you'd expect. Our compact rigs fit through 5ft gaps and can reach tight garden sites. Drilling is done in 1–3 days per borehole depending on geology. We use dust suppression and restore the ground afterwards. Most clients find it less disruptive than a typical extension.
What are the running costs compared to oil?
A GSHP produces roughly 4kW of heat for every 1kW of electricity it uses. For a typical rural oil-heated home using 2,500 litres/year (approximately £2,000+ at current prices), a GSHP typically reduces running costs by 40–60% — with price stability not tied to oil markets.
How long do ground source heat pumps last?
The heat pump unit itself has a typical lifespan of 20–25 years. The ground loops (the underground pipework) last 50+ years — longer than most buildings. This is a significant advantage over air source heat pumps, which typically last 15–20 years.
Can I combine a GSHP with solar panels?
Yes, and it's increasingly common. GSHP electricity demand matches solar generation well, especially in shoulder seasons. Pairing a GSHP with solar PV and a battery can reduce running costs to near zero on sunny days.
What areas do you cover?
Our core catchment is Sussex, Surrey, Hampshire, Kent, Wiltshire and Dorset, where we have concentrated project experience and rapid response times. We regularly travel as far as Devon and beyond for larger projects and commercial installations — get in touch with your postcode and we'll tell you straight away whether we can help.
Do I need planning permission?
In most cases, no. Ground source heat pump installations are usually classed as 'permitted development' under UK planning rules. Exceptions apply to listed buildings, conservation areas, and Areas of Outstanding Natural Beauty where we'll advise on the specific process.
