An air source heat pump (ASHP) is an energy-efficient heating system that extracts heat from the outside air to warm your home and provide hot water. Even in cold temperatures, it can generate heat by transferring and compressing ambient air using a refrigeration cycle.
The most common type in the UK is the air-to-water system, which supplies hot water to radiators or underfloor heating and your hot water cylinder.
ASHPs typically produce three to four times more energy than they consume in electricity, making them highly efficient and environmentally friendly. They help reduce running costs and carbon emissions and may be eligible for funding through schemes like the Boiler Upgrade Scheme.
At PHS Engineers Ltd, we design, install, and maintain ASHP systems across Suffolk for both homes and businesses.
At PHS Engineers Ltd, we provide professional air source heat pump installation services across Suffolk, supporting homes and businesses in their move to low-carbon heating. Our MCS-certified engineers carry out a full assessment of your property to design a bespoke system that meets your heating and hot water needs, while ensuring maximum efficiency.
Whether you’re replacing an ageing boiler or incorporating renewable heating into a new build, we manage every aspect of the process, from equipment supply and installation to commissioning and handover.
All installations are completed in line with current Building Regulations, and we offer expert guidance on government incentives such as the Boiler Upgrade Scheme. Our goal is to deliver a future-ready heating solution that saves energy and reduces long-term costs.
We work with leading brands, including but not limited to:
Whether it’s a domestic retrofit or a large-scale commercial system, we have the experience and technical expertise to get it right first time.

Air source heat pumps (ASHPs) are a highly efficient and environmentally responsible alternative to traditional heating systems and they’re suitable for a wide range of properties across Suffolk. Whether you live in a modern semi-detached home, a rural cottage, or a larger detached property, an ASHP could be a smart investment in long-term comfort and energy savings.
These systems work best in well-insulated homes, where they can maintain steady indoor temperatures using lower flow temperatures than conventional boilers. If your property is already energy-efficient or undergoing a renovation that includes insulation upgrades, an air source heat pump can perform exceptionally well.
Key advantages of ASHPs include:
However, there are practical considerations. You’ll need sufficient outdoor space for the unit with good airflow, and installation may require planning permission in certain areas, particularly in conservation zones or listed buildings.
If you’re unsure whether an air source heat pump is suitable for your home, our engineers can carry out a detailed assessment and offer expert guidance on system compatibility, cost-effectiveness, and expected performance.
The cost of installing an air source heat pump in the UK typically ranges from £7,000 to £14,000, depending on your property size, system specification, and installation complexity. Commercial systems may cost more.
Key factors affecting cost include:
While the initial investment is considerable, ASHPs offer long-term savings on energy bills, especially when replacing oil, LPG, or electric heating. Grants of up to £7,500 are also available through the Boiler Upgrade Scheme (BUS) for eligible properties.
At PHS Engineers Ltd, we offer transparent pricing and tailored advice to help you choose the most cost-effective solution for your Suffolk property.
When designed correctly and fitted in a home with good insulation, air source heat pumps can be up to 300% more efficient than other forms of heating. Here are some numbers to compare:
Please note that these figures can change based on energy prices.
You can also expect that there will be maintenance costs much like other heating sources. In order to maintain your RHI tariff payments, you’ll need to inspect your air source heat pump each year. This can cost around £200 per year if serviced by a qualified heating engineer.
Choosing to install an air source heat pump is a great decision because it gives you access to a number of grants. This is part of the Government’s plan to reduce reliance on fossil fuels and switch to environmentally-friendly options such as air source heat pumps. As such, they have been included in the Renewable Heat Incentive (RHI) which allows you to reduce the cost of installation and also gain access to lower tariff costs at 10.85p/kWh.
The RHI offers homeowners quarterly payments over a seven-year period based on the annual heating consumption of their property, and also the amount of environmentally-friendly energy it produces. At the current rate of 10.85p/kWh for air source heating, you could gain a total of £7,000 through RHI payments over 7 years. This figure is based on an average three-bedroom house that uses 15,000kWh of heating per year.
Since it uses electricity it’s not completely carbon-neutral. However, a heat pump can be a great way to reduce your carbon emissions since it doesn’t use fossil fuels.
It’s recommended to insulate your home and have it up to modern Building Regulation standards to ensure that your air source heat pump can work efficiently.
If your building is well-insulated and you have some space outside your home to install the air source heat pump, then it can be a good choice as an environmentally-friendly way to heat your home.
Air source heat pumps are up to 300% efficient. This means that for every unit of energy it uses, it outputs roughly three times the units in heat energy for the property.
If you’re currently installing or have installed an underfloor heating system, then you’ll be glad to know that an air source heat pump can work perfectly fine with underfloor heating as well. An air source heat pump is extremely efficient when it needs to produce low water temperatures, and this makes it great for an underfloor heating system.
Whether you’re installing a new system, booking a service, or need urgent repairs, our friendly team is here to help.
