Air Source Heat Pump Installation in Hampshire
MCS-certified installation with your Boiler Upgrade Scheme grant managed for you
Rising energy bills and tighter carbon targets are pushing homeowners and businesses to rethink how they heat their buildings. An air source heat pump takes natural warmth from the outside air and uses it to provide heating and hot water all year round, even in cold UK winters.
Rawlings Renewables designs, installs and services air source heat pumps across Hampshire. We are MCS certified, and we manage your Boiler Upgrade Scheme grant for you, taking it straight off your quote.
Unlike gas and oil boilers, air source heat pumps run at lower flow temperatures. For every kilowatt of electricity they use they can generate around three kilowatts of heat for your radiators, underfloor heating and hot water cylinder — because they move heat rather than burning fuel.
The outdoor unit sits at the side or back of the property where there is ample airflow, and the indoor unit is usually more compact than a standard boiler. Paired with onsite solar, the system can run on almost entirely renewable energy.
Why Choose Rawlings Renewables for Your Heat Pump Installation
How Our Heat Pump Installation Works
Survey and heat-loss calculation
We visit your property and check your current heating, insulation, radiators and hot water needs, then confirm whether a heat pump is the right fit. Room-by-room heat loss, not rules of thumb.
Design and quote
We design a system sized for your property and give you a clear, itemised quote with your grant already deducted, so you can see exactly what you would pay.
Grant application
We are registered to apply for and redeem the Boiler Upgrade Scheme grant, so we handle the application for you. You never front the money and wait to be reimbursed.
Installation
Our engineers fit the heat pump, cylinder and controls. We confirm the timescale for your property in the quote, since it depends on the system and any pipework or radiator changes.
Commissioning and handover
We test the system, register the installation under MCS and show you how to run it, so you are confident with the controls before we leave.
Servicing and aftercare
We keep your system running with an annual service and ongoing support, from the same local team that installed it.
What Is an Air Source Heat Pump and How Does It Work?
An air source heat pump is installed outside your property. It takes heat from the outside air and uses it to heat your radiators or underfloor heating and your hot water. Because it moves heat rather than burning fuel it is far more efficient than a conventional boiler, and it keeps working effectively in cold UK weather. For a deeper look at how they work, see the Energy Saving Trust guide to air source heat pumps.
Boiler Upgrade Scheme: Up to £9,000 Off, Managed for You
Funding should never stand between you and a better heating system. The government’s Boiler Upgrade Scheme gives eligible homes and small businesses in England and Wales £7,500 off an air source or ground source heat pump. If you are replacing an oil or LPG system in an eligible off-gas-grid property, the grant rises to £9,000 for applications between 21 July 2026 and 31 March 2027. We are registered to apply for and redeem it on your behalf, so we take the grant off your quote and you only pay the balance — no paperwork, and no waiting to be reimbursed. Grant amounts and eligibility are set by government and can change; we confirm yours at the survey, and you can read the official rules on GOV.UK and Ofgem.
Air Source Heat Pump Cost in Hampshire
What an installation costs depends on your property’s size and insulation, whether your existing radiators and hot water cylinder can be reused, and how much pipework is involved. Rather than quote a headline figure that may not apply to your home, we give you a fixed, itemised quote after your survey with the Boiler Upgrade Scheme grant already deducted. If the numbers don’t work for your property, we will say so — we also fit solar panels and supply HVO fuel where those are the better route.

Ground Source, Solar and Servicing
Rawlings Renewables is the renewable energy division of Rawlings Fuels, backed by thirty years of keeping Hampshire properties warm. Alongside air source we install ground source heat pumps where there is land for the loops, solar PV to offset what a heat pump costs to run, and HVO fuel for properties that are not ready to switch. One team looks after everything, including heat pump servicing and maintenance for any make, so you always know who to call.
Government grant, managed for you
The government pays £7,500 towards an air or ground source heat pump; this increases to £9,000 if you have an existing oil-fired or LPG system installed. We handle the application and deduct it from your quote.
MCS certified
Every install is certified under the Microgeneration Certification Scheme — the requirement for grant eligibility.

Frequently asked questions about air source heat pumps
What is an air source heat pump?
An air source heat pump is installed outside your property and takes heat from the outside air to heat your home and hot water. It works effectively even in cold UK weather and uses significantly less energy than a standard boiler.
Can an air source heat pump provide hot water as well as heating?
Yes. An air source heat pump can supply both central heating and domestic hot water. We size the system and cylinder to match your household’s needs.
How much grant is available for an air source heat pump?
The Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump in England and Wales. For eligible off-gas-grid properties replacing oil or LPG heating this rises to £9,000, for applications between 21 July 2026 and 31 March 2027. We manage the application and deduct the grant from your quote.
Am I eligible for the Boiler Upgrade Scheme?
The scheme covers properties in England and Wales that currently use a fossil fuel or direct electric heating system, and the installer must be MCS certified. Rules can change, so we confirm your eligibility at your survey.
Is an air source heat pump a replacement for a boiler?
In most cases, yes. An air source heat pump can replace your existing boiler as your main source of heating. We survey your property first to confirm the best setup.
How much does an air source heat pump cost in Hampshire?
It depends on your property’s size, insulation, existing radiators and hot water cylinder. Rather than quote a range that may not apply to you, we give a fixed, itemised quote after your survey with the grant already taken off.
Do air source heat pumps work in cold weather?
Yes. Modern air source heat pumps work in sub-zero temperatures. A correctly sized system, designed from a proper heat-loss calculation, keeps your home warm through the winter.
Will I need new radiators or a new hot water cylinder?
It depends on your property. Some homes need larger radiators or a new cylinder to get the best from a heat pump. We check this at survey and include anything needed in your quote.
Is planning permission needed for an air source heat pump?
Often it isn’t, because many installations fall under permitted development, but there are conditions covering the unit’s position and noise. We advise you on this at survey.
How often does an air source heat pump need servicing?
We recommend a simple annual service to keep your system running reliably. We service the systems we install, and any other make too.
Why does my installer need to be MCS certified?
MCS certification is a requirement for Boiler Upgrade Scheme grant eligibility. Every Rawlings Renewables installation is certified under the Microgeneration Certification Scheme, so you can claim your grant with confidence.
