Powering Your Future Sustainably
Air Source Heat Pump Installation Services
Our expert ASHP installation services are provided by MCS Certified installers ensuring heating system connections, components and wiring are compliant, and manufacturer and installation warranties are valid.
When considering a heat pump to replace your existing boiler, it is essential to arrange a full technical survey before committing to a quote. Every aspect of your property’s heat efficiency must be recorded and analysed to identify any required upgrades prior to installation.
Heat pumps are a super-efficient way to heat your home, they work all year round, and maintain performance even down to -15° temperatures!
Grants are currently available in England until March 2027.

Is A Heat Pump Right For You?
Why Heat Pump Myths Persist
Common concerns about heat pumps are mostly unfounded. Research shows that many people believe heat pumps cannot cope with unpredictable British winters, are noisy, and can’t provide sufficient hot water.
Anecdotal experiences are often based on earlier models that were most likely undersized for the property, and did not take into account the strict heat-loss calculations that are now a fundamental requirement for any professional and compliant installation service.
Since EPC’s became mandatory, much of this information is public access, and forms the basis of modern technical surveys. From construction materials and insulation to room dimensions, radiator types and window sizes, the list is exhaustive for good reason. Any necessary upgrades are quickly identified and should be included in the proposal.
This ensures that the vastly more efficient, lower running temperature of a heat pump system will provide a consistent temperature throughout the home. A standard boiler will switch on and off to achieve this, overheating the property and allowing it to cool, then repeating the cycle over and over. A heat pump runs more continuously at the optimum temperature, as it doesn’t need to overheat to achieve this.
When paired with a solar pv and battery combination, heating your home suddenly becomes a guilt-free pleasure!
Noise And Water Temperature
Modern Heat Pump Facts
The latest generation of heat pumps incorporate noise suppression technology built into the casing and mounts, and even include new fan-blade designs that reduces noise levels even further. Coupled with “night mode” speed reduction, a modern heat pump can generate as little as 35 db at 1m, equivalent to a whisper in a library.
Heat pump compatible cylinders will store hot water at 55°C, far hotter than the maximum recommended temperature (40°C) for showering, and easily sufficient to achieve 21°C room temperature when correctly sized.

🎁 Save Up to £9,000 on Your Heat Pump Upgrade
You could get up to £9,000 towards your installation via the UK Government’s Boiler Upgrade Scheme (BUS).
- Standard Mains Gas Replacement: £7,500 Grant applied directly to your quote.
- Replacing Heating Oil or LPG: £9,000 Grant (increased off-grid funding to protect rural properties from rising oil prices).
Zero Paperwork Stress: As MCS-certified installers, Prime Energy Solutions manages the entire Ofgem application process on your behalf and deducts the full grant amount upfront from your quote—leaving you with only the remaining net cost.
Who Qualifies for the Grant?
- Property Location: Homes and small commercial properties across England and Wales.
- Ownership: Homeowners, self-builders, and residential landlords.
- System Replaced: Replacing an existing fossil-fuel system (mains gas, heating oil, LPG, or electric storage heaters).
- EPC Condition: A valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation (if insulation is required, we can assist before fitting).
Frequently Asked Questions
How much does an Air Source Heat Pump cost to install, and how does the £7,500 grant work?
A typical domestic heat pump installation ranges between £9,000 and £14,000 before incentives, depending on your home’s size, heat loss, and cylinder setup.
However, under the UK government’s Boiler Upgrade Scheme (BUS), eligible homeowners in England and Wales receive an upfront £7,500 grant towards installation. This brings your net out-of-pocket cost down to £1,500 to £6,500—often making it comparable to fitting a high-end replacement gas boiler.
As MCS-accredited installers, we handle the entire BUS application with Ofgem on your behalf and deduct the £7,500 directly from your quote—no chasing cash back.
Are heat pumps cheaper to run than a traditional gas, oil, or LPG boiler?
Yes, when properly sized and paired with modern energy tariffs. Traditional boilers convert 1 unit of fuel into less than 1 unit of heat (~85%–92% efficiency). An Air Source Heat Pump operates at 300% to 400%+ efficiency (SCOP 3.0–4.0), generating 3 to 4 kWh of heat for every 1 kWh of electricity consumed.
- Replacing Oil or LPG: Homeowners typically see immediate annual energy bill reductions of 30% to 50%.
- Replacing Mains Gas: Running costs remain roughly comparable on standard tariffs, but pairing your heat pump with a smart off-peak heat pump tariff drops heating costs substantially below mains gas.
Will I need to change all my radiators for a heat pump installation?
Not necessarily. Heat pumps operate at lower, more consistent water flow temperatures (around 45°C–55°C compared to a gas boiler’s 65°C–70°C) to maximize efficiency.
- In many well-insulated homes, existing double-panel radiators or wet underfloor heating systems work perfectly.
- If certain rooms require larger surface areas, we typically only need to upgrade 1 to 3 key radiators to larger Type 22 or Type 33 models, which we include directly in your upfront proposal.
Will an Air Source Heat Pump keep my home warm during freezing temperatures?
Yes. Modern air source heat pumps use advanced refrigerants (such as R290 natural refrigerant) engineered to extract heat from outdoor air in temperatures as low as -20°C. (In fact, over 60% of homes in Norway rely on heat pumps for heating).
Unlike a boiler that cycles on and off at intense temperatures, a heat pump delivers continuous, steady, baseline warmth throughout your home. Furthermore, modern units operate at a whisper-quiet hum (around 40–45 dB at 1 metre), making them no louder than a domestic kitchen fridge.
Where is the outdoor heat pump placed, and how much indoor space do I need?
An air source heat pump system consists of two primary components:
- Outdoor Unit: A compact fan unit (roughly 1m wide by 1m high) mounted outside on an exterior wall base or ground pad with clear airflow around it.
- Indoor System & Cylinder: If you are replacing a combi boiler, you will need space indoors for a modern, unvented hot water cylinder (roughly the footprint of a standard fridge-freezer). This cylinder fits into an airing cupboard, utility room, garage, or loft.
