A heat pump can cost £7,000 to £14,000 to install in a UK park home
If you live in a park home and are considering a heat pump, the upfront cost is likely your first question. The total installation price for a standard air source heat pump in a park home typically ranges from £10,000 to £18,000 before any grant is applied, according to the Energy Saving Trust and MCS-certified installer data (Energy Saving Trust, 2026). After the £7,500 Boiler Upgrade Scheme (BUS) grant, your net cost falls to between £2,500 and £10,500, depending on your park home’s size and the complexity of the installation.
Ground source heat pumps are rarely suitable for park homes due to the land area required and significantly higher installation costs (Energy Saving Trust, 2026). This article focuses entirely on air source heat pumps. The final cost you pay varies with your park home’s age and insulation level, which determines the heat pump size needed to heat the property effectively.
A heat pump in a park home typically saves £200 to £500 per year on heating bills compared to electric storage heaters
The annual saving depends on what heating system you are replacing. Switching from electric storage heaters to a heat pump yields the largest savings, up to £500 per year, based on Energy Saving Trust and Ofgem tariff data for 2026 (Energy Saving Trust, 2026). If your park home currently uses LPG or oil, the saving is smaller, around £150 to £300 per year, because those fuels have higher running costs per kWh (Sutherland Tables, GOV.UK, 2026).
The actual saving you achieve is highly dependent on the heat pump’s Seasonal Coefficient of Performance (SCOP). A SCOP of 3.0 means the heat pump produces three units of heat for every unit of electricity it uses. A well-insulated park home with a SCOP of 3.5 or higher achieves the highest savings. To estimate your own saving, compare your current fuel cost per kWh from your bill against the heat pump’s running cost at a SCOP of 3.0, using the latest Ofgem price cap data (Ofgem, 2026).

A park home must have a minimum insulation standard (U-value of 0.30 W/m²K or better) for a heat pump to be cost-effective
Insulation is critical for heat pump performance. The Energy Saving Trust and the National Energy Foundation recommend that park homes have wall and roof insulation achieving a U-value of 0.30 W/m²K or better (Energy Saving Trust, 2026). A U-value measures how quickly heat escapes through a surface; lower numbers mean better insulation. Without this standard, you will need a larger, more expensive heat pump that runs less efficiently.
Many older park homes built before 2000 have insulation levels closer to 0.60 to 0.80 W/m²K, which would require a significantly larger heat pump and reduce your savings (DESNZ, 2026). Retrofitting insulation, for example by adding external cladding or internal lining, can cost £2,000 to £5,000. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing.
Before you buy a heat pump, an installer must carry out a heat loss calculation using the MCS 020 standard. This calculation tells you the exact heat pump size your park home needs. Do not accept a quote without this calculation.
A heat pump is suitable for a park home if it has a modern
Your park home must meet several conditions for a heat pump to work effectively. The property should have double or triple glazing, draught-proofing, and a minimum of 100mm of roof insulation, according to the Energy Saving Trust and National Energy Foundation checklist (Energy Saving Trust, 2026). The outdoor unit needs a clear, level space, typically 1 metre by 1 metre, with good airflow and away from windows and neighbouring properties, as set out in MCS installation standards (MCS, 2026).
Park homes with a timber or lightweight frame may need additional structural reinforcement to support the outdoor unit. Check with the heat pump manufacturer or your MCS installer before proceeding. Your park home must also have a mains electricity supply with sufficient capacity. Most park homes do, but if an upgrade is needed, it can cost £500 to £1,000.
The standard answer a heat pump is a good investment for a park home if you replace electric storage heaters and have adequate insulation
To answer the search query “heat pump park homes uk”, suitability is high for park homes with good insulation and electric heating. It is less suitable for those with poor insulation or currently using LPG or oil. The payback period for replacing electric storage heaters is typically 5 to 10 years after the BUS grant, based on Energy Saving Trust payback modelling (Energy Saving Trust, 2026).
For LPG or oil replacement, the payback period is longer, at 8 to 15 years, and may not be worthwhile unless you plan to stay in your park home for 10 years or more. The three key factors that tip the balance are your insulation level, your current fuel type, and the availability of the £7,500 BUS grant. How to check your park home insulation rating
You must use an MCS-certified installer to qualify for the £7,500 Boiler Upgrade Scheme grant
The Boiler Upgrade Scheme requires your heat pump to be installed by an MCS-certified contractor (DESNZ, GOV.UK, 2026). MCS certification ensures the installer follows technical standards, including MCS 020 for heat pumps, and provides a warranty-backed installation. To find a certified installer, check the MCS register at mcscertified.com or use the TrustMark scheme at trustmark.org.uk for vetted tradespeople (TrustMark, 2026).
Additional checks: Gas Safe Register is not relevant for heat pumps, as they use electricity, not gas. If electrical work is needed, NICEIC or NAPIT registration may apply, but MCS certification is the primary requirement for claiming the grant. Boiler Upgrade Scheme eligibility checklist
