Government Funding Available

Up to £16,500

available in grants and 0% loans

Scottish homeowners can get up to £7,500 towards an air source heat pump through the Home Energy Scotland Grant and Loan, plus an interest-free loan of up to £7,500 to cover the rest. That’s up to £15,000 in support. Rural and island properties can access an increased £9,000 grant, bringing the total available to £16,500.

Heat pump installations also carry 0% VAT until March 2027, another saving on top of the grant.

What Is an Air Source Heat Pump?

An air source heat pump takes heat from the outside air and uses it to heat your home and hot water, like a fridge working in reverse. The outdoor unit pulls in air and extracts heat from it, even when it’s cold, then compresses that heat to boost the temperature, which is pumped around your radiators, underfloor heating and hot water cylinder.

We install Vaillant heat pumps, designed to operate efficiently in outside temperatures as low as -21°C, while still delivering a warm home.

Key benefits

How It Works

We assess your home

A free survey to look at your current heating system, insulation, radiators and hot water needs, so we can size your Vaillant heat pump correctly for your property.

We design your system

We’ll design a heat pump system suited to your home, including any radiator or pipework changes needed, and talk you through exactly what to expect.

We handle the funding

We’ll guide you through the Home Energy Scotland Grant and Loan, and make sure you understand exactly what you’re eligible for before committing to anything.

Installation and handover

Our team installs your system with minimal disruption, then walks you through how to get the most out of it, including how it works alongside solar or battery storage if you have it.

Is a Heat Pump Right for Your Home, Even in Scotland?

It’s a common myth that heat pumps struggle in colder climates, they’re actually widely used across Scandinavia and other genuinely cold countries, and Vaillant’s systems are designed for exactly this kind of weather, operating efficiently down to -21°C outside.

That said, not every home is ready for a heat pump without some changes, and we’ll always be upfront about that rather than oversell you. We look at your current insulation, radiator sizing, and hot water setup as part of your free survey. If your home’s ready to go, we’ll show you exactly how. If it needs a few changes first, we’ll tell you that too.

Our Process, Not Just Our Price

Choosing the right installer matters more than choosing the cheapest one. If a system isn’t sized properly, it won’t heat your home efficiently and will cost more to run in the long term. That’s why every Vaillant heat pump we fit starts with a proper survey and a system genuinely designed around your home, not a one-size-fits-all quote.

“We had a great experience with Greener Roof Co. After getting quotes from quite a few companies, my wife and I decided to go with them because they offered the best balance of quality and price. Looking back, it was definitely the right decision.”

We had a very positive experience with GRC, after a very prompt response the whole process was dealt with professionally and with meticulous attention to detail. We were offered a great package which meets our needs perfectly and every detail was shared with us along the way. The team on the job were very thorough, tidy, informative and helpful. We are delighted with the job they did and just how good the kit looks in our home. Would definitely recommend them without hesitation.

 Trustindex verifies that the original source of the review is Google. Excellent price and service. Driveway had to dug up to allow a cable to be run from the garage to the house. The job was very neat and the battery and software are excellent.

 Trustindex verifies that the original source of the review is Google. all went well but initially was told that all cables/meter would fit within my current meter cupboard. unfortunately electrician on installation day said it needs to be done outside of it:( also the hole drilled thru the wall for the cable hasnt been sealed at all. i mentioned that to the manager next day and he said someone would come to seal it but nobody showed up:(

Air Source Heat Pump FAQ

How much does an air source heat pump cost?

Typical installation costs range from around £8,000 to £15,000, depending on the size of your home and the system specified. With grants applied, most homeowners pay significantly less. We’ll give you a clear, no-obligation quote after your free survey.

How much of the cost is covered by grants?

Scottish homeowners can get up to £7,500 towards the cost through the Home Energy Scotland Grant and Loan, plus an interest-free loan of up to £7,500 to cover the rest, up to £15,000 in total support. Rural and island properties can access an increased £9,000 grant, bringing the total available to £16,500.

Will a heat pump heat my home properly in winter?

Yes. Vaillant’s heat pumps are designed to work efficiently even in very cold weather, operating down to around -21°C outside while still delivering a warm home. Properly sized and installed, they perform reliably across Scotland throughout the year.

How long does installation take?

Most domestic installations take between 2 and 4 days, depending on the size and complexity of the system. We’ll give you a clear timeline as part of your survey and quote.

Can I use a heat pump with solar panels?

Yes. Heat pumps and solar PV work well together. Solar can help power your heat pump during the day, reducing how much you rely on the grid, and pairing with battery storage lets you make use of that generation in the evening too.

Do I need to upgrade my radiators?

Sometimes, but not always. Heat pumps run most efficiently at lower temperatures than a traditional boiler, so larger radiators or underfloor heating can help, but many homes work well with their existing setup. We’ll assess this during your survey.

How much can I save on heating bills?

Savings vary depending on your current system, insulation, and usage, but many homeowners save up to 60% on heating and hot water costs compared to older, inefficient heating systems. We’ll give you a realistic estimate based on your specific property.
