Find an installer for a ground source heat pump in Portsmouth
Properties off the gas grid with space outside are the usual candidates for a ground loop. Measure or estimate the usable garden area.
Describe your job in Portsmouth, and up to four independent heat pump businesses may respond, depending on the type of job and where each business operates. Matching costs nothing, and every quote can be declined.
What ground source heat pump installation involves
A ground source system pulls low-grade heat from the earth through a loop of pipe filled with a water and antifreeze mix. The heat pump inside the house raises that heat to heating temperature and feeds the radiators, underfloor heating and hot water cylinder. The ground loop is a big part of the job and of the price.
What installers ask about first
- A tank that is expensive to refill each year
- Several acres or a large lawn that could take a loop
- A self-build where groundwork can be added
- Underfloor heating already fitted or planned
- Little space, so a vertical loop is being considered
What the installation team does
The outdoor work and the indoor work are usually separate phases. A typical job includes:
- Surveying the ground, the site access and the heat loss, then agreeing the design.
- Cutting trenches for horizontal collectors, or drilling boreholes for vertical ones.
- Connecting the collector pipes to a manifold, then pressure-testing and filling with antifreeze mix.
- Fitting the heat pump, buffer or cylinder and controls inside the plant room.
- Commissioning the system, balancing flow rates and showing you how to read the controls.
Horizontal loop or borehole
A horizontal loop needs trenches or a large excavated area, usually in a garden or field. A vertical loop uses one or more boreholes, often 50 to 150 metres deep, and suits smaller plots at a higher cost. Ask each installer why they prefer one over the other for your site.
What to agree before work starts
Tell the installer where machines can reach and where services run under the garden. Agree who reinstates lawns and paths, what happens to spoil, where the manifold chamber goes and how long the garden will be out of use.
Collector testing and garden reinstatement
Ask for the collector test records before the trenches are covered. Keep a drawing of the buried pipe route for later garden work. The quote should say whether soil settlement, reseeding and replacement planting are included.
The cost of ground source heat pump installation in Portsmouth
Expect something in the region of £20,000–£45,000. Each business sets its own prices. A horizontal loop on easy ground with a modest heat demand sits at the lower end. Long trenches, rock, drainage problems or a high heat demand are in the middle. Deep boreholes, large houses and extensive internal pipework take the job to the top of the range or beyond.
Check whether the written price includes equipment, labour, survey charges and VAT. Allow 2–6 weeks as a guide for the work itself; equipment lead times and awkward access can add to it.
Before you send the form
Describe the size and shape of the garden or field, the soil if you know it, and any trees, drains, tanks or buried services. State whether the house has underfloor heating and what type of fuel it uses now.
Check exactly what the price covers. Ask for the design heat load, the heat pump model and size, the type and length of the collector, the cylinder, the controls and who reinstates the ground. Check whether an independent ground survey or borehole survey is included.
Rules that apply to the work
A buried horizontal collector is often possible without planning permission in England, but conservation areas, listed buildings and flood zones can change that. Boreholes may need extra consents and should be drilled by a competent contractor. Installations by an MCS-certified business can qualify for the Boiler Upgrade Scheme in England and Wales.
Council questions for this area can go to Hampshire County Council. Ask your installer which consents they will deal with and which are left to you.
Getting a business to Portsmouth
Businesses covering Portsmouth, Hampshire need the full postcode. Tell them about permit parking or a tight drive. Photographs of the garden, access gate and existing plant room help with planning. The existing heating matters as much as the postcode, so describe your own system.

Use the free enquiry form to describe the job. Mention how much of the garden you can afford to lose for a season, and whether a drilling rig could reach the plot. Businesses that join are asked for insurance details and references. Before booking, ask to see current insurance and the qualifications needed for the quoted work. We only pass the enquiry on: advice, pricing and the work itself come from the business you pick.
What to check before arranging this service
How can I compare quotes for ground source heat pump installation in Portsmouth?
Fill in one enquiry form with your postcode, the size of the garden and the way the house is heated now. It can reach up to four independent heat pump businesses working in Portsmouth. Replies depend on the job and availability. You decide whether to book anyone.
Roughly how much is ground source heat pump installation in Portsmouth?
We use £20,000–£45,000 as a UK guide. Businesses in Portsmouth price their own work, and the ground conditions, the loop type and the size of the house affect the total. A written quote should list equipment, labour, VAT and any survey or call-out charge.
How much land does a ground source heat pump need?
A horizontal loop usually needs a garden or field several times the floor area of the house. Boreholes need far less ground but cost more. The installer should size the loop from the heat load, not guess from the plot.
Is a ground source heat pump more efficient than an air source one?
Ground temperature is steadier than air temperature, so efficiency can be higher in winter. The extra groundwork cost means the saving takes longer to repay. Ask for running cost figures for your own house.
Will the garden recover after a horizontal loop is installed?
Usually, yes. Lawns and borders can be reinstated, though trenches settle and shrubs may need replanting. Agree the reinstatement in writing before work starts.
How long should I allow for ground source heat pump installation?
Allow 2–6 weeks as a guide. Ask each business to state the type of ground loop and why it suits the plot. Equipment lead times, groundwork or electrical upgrades can add to that, so ask when the property will be without heating.
