1. Research

Who is eligible for heat pump installation funding?

Owner-occupiers in Scotland can use our Funding Finder to see financial support options for home improvements and renewable energy.

This guide concentrates on heat pump installation and the Home Energy Scotland Grant and Loan for owner-occupiers in Scotland.

If you are a homeowner in Scotland and live in the property, you may be eligible for a Home Energy Scotland Grant and Loan to help with the installation costs.

Self-builders can apply for home renewables systems like heat pumps. Not all financial support available covers self-build homes.

Private landlords or businesses should read our advice about Private Rented Sector Landlord Loans.

Read our grants and funding guide for heat pump installations for more information.

Which type of heat pump is best for you?

There are quite a few different types of heat pumps, but the most common in Scotland are air source and ground source heat pumps. Each has different installation requirements and costs. Read our heat pump guide for more information and our myth-busting article, too.

Our Home Renewables Selector can help you work out if a heat pump or other renewable technology will suit your home.

Head to Scotland's Green Homes Network for a more practical demonstration of heat pumps and renewables. The Green Homes Network showcases all sorts of houses across the country whose homeowners have installed renewable energy systems.

Network members want to share their journey to renewables. We can put you in touch with members to find out more. In some cases, we can arrange a visit to their homes if you wish to see renewable energy systems in action. They can explain costs, how their renewable energy systems work, and answer any questions you may have. This advice can help you towards making an informed decision about a heat pump.

Heat pump funding eligibility

You must meet several conditions to claim Home Energy Scotland funding for a heat pump.

  • You must be the owner-occupier.
  • You need a qualifying energy report that recommends a heat pump for your home. This could be a free Home Energy Scotland report. Check our Home Energy Scotland Grant and Loan: in detail webpage.
  • You must use a Microgeneration Certification Scheme (MCS) installer and products.
  • Your post-install EPC can’t recommend loft or cavity wall insulation. If required, you must install these before you can claim your funding — but funding is available for these measures, too. See below for more details.
  • Work must not commence before a funding offer has been made.

If unsure, call Home Energy Scotland for free on 0808 808 2282 for advice.

It's always good to review whether your home could benefit from insulation first. To be able to claim Home Energy Scotland Grant and Loan funding, your home must have adequate loft insulation and cavity wall insulation if you have a loft and cavity walled home. Solid wall and floor insulation may be too expensive or disruptive, so isn't a requirement to access funding but it's still worth looking into. Speak to our advisors who can provide impartial advice on heat pumps and whether your home could benefit from insulation.

There are a variety of home reports that validate your home's suitability for a heat pump. These reports may also recommend home improvements such as loft insulation to ensure your home is energy efficient. Check our Home Energy Scotland Grant and Loan: in detail webpage.

After you receive a funding offer and install your heat pump, you will need to get a new EPC to claim your funding. This post-install EPC should show the heat pump has been installed and that there are no recommended energy efficiency measures outstanding to meet the funding requirements.

Your property may already have an EPC. Search the Scottish EPC Register to check – you can also see if your EPC currently recommends loft or cavity wall insulation. If your property doesn’t have an EPC, Home Energy Scotland can talk to you about your home and potentially provide a report to support a funding application. When you need an EPC for your home, the EPC register can help you find an assessor near you. Only registered Domestic Energy Assessors can issue an EPC.

You also need to use an MCS-certified installer when installing your heat pump. Find a complete list of certified installers and products at the Microgeneration Certification Scheme — see below for more.

2. Get advice from Home Energy Scotland

If you haven't contacted us by now, it's a good idea to get in touch for free, expert, and impartial advice. Home Energy Scotland advisors can answer questions you may have about heat pumps and energy efficiency and provide more information about schemes and financial support.

You can ask about financial support, heating systems, steps in the process, and many more of the heating options and help available. If you're eligible to apply for the Home Energy Scotland Grant and Loan, only Home Energy Scotland can provide you with an application form. And we may be able to arrange a visit, or a call from a specialist to assess your home, too.

If other support is available, advisors can discuss that with you too. But remember the Home Energy Scotland Grant and Loan is not linked to other schemes, nor is eligibility for the loan indicative of eligibility for additional support.

Contact us on 0808 808 2282 for free. Speaking with Home Energy Scotland is vital in understanding the heat pump installation process and possible financial aid. It's a condition of funding that you don't start work before you receive a funding offer - so it’s best to speak to us early in the process.

3. Get a qualifying recommendation report

There is some paperwork involved with heat pump installation and the Home Energy Scotland Grant and Loan. These requirements are in place to protect you as a consumer, maintain high work standards, and ensure the heat pumps work correctly.

If you decide to apply for funding, you need to have a qualifying energy report that shows a heat pump may be suitable for your home. The report must be included with your Home Energy Scotland Grant and Loan application.

There are several types of qualifying recommendation reports we can accept for heat pumps:

  • Home Renewables Selector Report (issued by Home Energy Scotland following a phone discussion).
  • Home Energy Improvement Report (issued by a Home Energy Scotland specialist following a phone discussion or visit).

Home Energy Scotland can discuss suitable qualifying reports for you, and your property may already have an EPC. Search the Scottish EPC Register to check.

Energy efficiency work required to claim the funding

It's a requirement that a certain level of insulation is in place before we can pay your funding to you. Your qualifying report or EPC may also recommend specific energy efficiency improvements. If your EPC recommends loft or cavity wall insulation, you will have to install these before, or at the same time, as your heat pump.

You must submit a post-install EPC to claim your Home Energy Scotland Grant and Loan. The post-install EPC will show the heat pump has been installed and that loft or cavity wall insulation is not or is no longer recommended. You can add the EPC cost to your Home Energy Scotland Grant and Loan if you wish.

Visit the Scottish EPC register to see if your home has a current and valid EPC.

he Home Energy Scotland Grant and Loan is available to help with these energy efficiency improvements too. Grant funding for energy efficiency improvements is up to 75% of the combined cost of the improvements, up to the maximum grant amount of £7,500, or £9,000 for households which qualify for the rural uplift. There are conditions attached to funding - read Home Energy Scotland Grant and Loan - in detail to find out more.

Energy Performance Certificate exceptions

In some cases you won't require a new EPC to claim funding.

  1. Self-build properties - you'll need to provide planning permission documents when applying. To claim the Home Energy Scotland Grant and Loan funding, you'll need to provide title deeds instead of a post-installation EPC.
  2. You installed an energy storage system only and have a current EPC which:
  • is three years old or less;
  • shows the renewables system the energy storage system is connected to; and
  • does not recommend any of the energy efficiency measures required by the loan.
  • Please note: solar PV and energy storage systems are only eligible for funding as part of a package together with a heat pump or high heat retention storage heaters. If you have already installed one or more of these improvements, you can apply for the remaining improvement(s) to complete the package. claims which do not meet this requirement will not be paid.

You'll also need to declare in writing that you haven't installed any other measures since your last EPC.

4. Quotes for your heat pump

Once your home’s considered suitable for a heat pump installation, the next step is pricing.

We recommend getting quotes from at least three different qualified installers. The Home Energy Scotland Grant and Loan requires you to use an installer registered with the Microgeneration Certification Scheme (MCS). This certifies that installers, and their installations, adhere to recognised industry standards.

It is a condition of the Home Energy Scotland Grant and Loan funding that your heat pump installer and products are MCS-certified.

You can find installers in your area (as well as customer reviews) on Energy Saving Trust's Renewables Installer Finder.

When getting quotes, you should expect your installer to give you:

  • a detailed breakdown of the technical specification and costs
  • an explanation of how they calculated your property's heat demand
  • information on the system’s maintenance requirements and running costs
  • an explanation of who is responsible for the system’s different components.

Now you have your recommendation report and your quotes, it's time to review everything before filling in your Home Energy Scotland Grant and Loan application form. Remember, heat pump installation can't start until you have received a Home Energy Scotland funding offer in writing.

5. Review everything and apply

At this point, it's a good idea to check you have everything in place.

You can also contact Home Energy Scotland on 0808 808 2282 for free, impartial advice and to get a funding application form if you do not already have one.

Points for you to check should include the following:

  • The proposed system’s efficiency values and available options.
  • Who is doing what? An MCS-certified installer must fit the heat pump. Do you need to arrange and pay for other trades, for example for any loft or cavity wall insulation?
  • Is the cost of integrating the new system with your home's existing system included?
  • Is the cost of safe removal and disposal of existing equipment included?
  • Warranty details which, if applicable, should be for a minimum of one year.
  • Any additional warranty from the manufacturer.
  • Your payment options, including consumer rules on deposits and deposit protection.
  • The right to cancel – you have the right to cancel within 14 days of signing a contract.
  • Whether the price covers the cost of commissioning the system authorising it as fit for service.
  • Details on whether the price includes aftersales service such as annual servicing.

Understand your consumer rights

Installing a heat pump, applying for funding, and making changes to your house are significant steps. The MCS sets out standards to which all certified installers must adhere. As part of this, MCS installers must be members of a consumer code. We recommend you read and understand their consumer code to know your rights and good industry practice.

Three codes are available to MCS installers:

You can find the relevant code for your installer by searching for their name in the MCS installer database. When you select their profile, it will give you more information about the company, including their consumer code.

How to fill in the Home Energy Scotland Grant and Loan application form

Be sure to have all relevant supporting documentation before starting your application for a Home Energy Scotland funding.


  • You can only apply using the application form provided to you by Home Energy Scotland.
  • Third parties - for example, installers or letting agents - are not allowed to apply for you.
  • You need a qualifying report to recommend the measure for which you are applying. You can submit this online - you don't need to send a paper copy.

6. Heat pump installation

Home Energy Scotland will send you a funding offer in writing if your application is approved.

Heat pump installation work can only commence after a funding offer is approved by us. You must complete the work within nine months of the funding offer. Don't forget; Home Energy Scotland advisors are on hand to help you with questions at any point.

Your installer should indicate how long the work will last and the level and type of disruption to expect.

7. Completion: what to check after installation

It's essential to keep all your paperwork together after your heat pump installation, both for the work and the Home Energy Scotland Grant and Loan.

We recommend you:

  • keep your commissioning certificate and warranty details in a safe place
  • keep a note of your installer’s contact details
  • know when to expect contact about annual servicing
  • leave a review on the Renewables Installer Finder - this is important; if your installer is registered here, your loan conditions require it
