The Home Energy Scotland Grant pays up to £7,500 towards a heat pump and adds an optional interest-free loan of another £7,500, with a further £1,500 uplift for rural and island homes (Home Energy Scotland, 2026). For an installer working north of the border, that is the single largest domestic funding pot most customers will ever touch, and it lands at a moment when 33% of Scottish households, around 830,000 homes, sit in fuel poverty (gov.scot, 2025).
Most published grant guides are written for England and stop at the Boiler Upgrade Scheme. Scotland runs its own system, funded by the Scottish Government and delivered by Energy Saving Trust, and the rules on eligibility, loans and installer accreditation are different enough to cost you a job if you quote as though it were the same scheme. This guide sets out what the grant covers in 2026, who can claim it, and how to build it into a quote.
Key Takeaways
- The Home Energy Scotland Grant gives up to £7,500 for an air, ground or water source heat pump, plus an optional interest-free loan of up to £7,500 on top.
- Rural and island homes get a £1,500 uplift on both the heating and the efficiency grant, taking the total available grant funding to as much as £18,000.
- Homeowners do not need to be on benefits to qualify, which makes this a far wider market than means-tested schemes like Warmer Homes Scotland.
- Your installation and product must be MCS certified for renewables, or TrustMark registered for solid wall, underfloor and roof insulation.
- Funding is first-come, first-served each financial year, and no work can start until the written offer arrives.
The Home Energy Scotland Grant and Loan, explained
The Home Energy Scotland Grant and Loan is a Scottish Government fund that gives homeowners a grant, an interest-free loan, or a mix of both to install clean heating and energy efficiency measures (Home Energy Scotland, 2026). It replaced the older Home Energy Scotland Loan and cashback route and now sits at the centre of domestic retrofit funding in Scotland, alongside the means-tested Warmer Homes Scotland programme.
The grant is the part that never gets repaid. The loan tops up whatever the grant does not cover, at 0% interest, so a customer can fund a full heat pump installation without touching a commercial finance product. For installers this is the key selling point: the headline is not a discount, it is a route to the whole job being paid for.
Scotland runs this scheme because it faces a heating problem that England does not. Around 81% of Scottish homes heat with gas, but almost two-thirds of rural dwellings sit off the gas grid and rely on more expensive electricity and oil (Citizens Advice Scotland, 2025). The grant is aimed squarely at moving those homes onto heat pumps, which is why the funding is weighted towards heating rather than standalone solar PV.
How much can you claim in 2026?
Heat pumps and heat network connections attract a grant of up to £7,500, with an optional interest-free loan of up to £7,500 on top of that (Home Energy Scotland, 2026). Energy efficiency measures such as insulation are funded at up to 75% of the combined cost, capped at a £7,500 grant, with the balance available as a loan. The table below sets out the headline figures.
- Air, ground or water source heat pump: Grant: £7,500 / Optional interest-free loan: £7,500
- Heat network connection: Grant: £7,500 / Optional interest-free loan: £7,500
- Solid wall insulation: Grant: £7,500 / Optional interest-free loan: £2,500
- Loft, cavity or underfloor insulation: Grant: £1,500 / Optional interest-free loan: £500
- Solar water heating (thermal or PV-T): Grant: Not available / Optional interest-free loan: £5,000
- Rural and island uplift (heating or efficiency): Grant: +£1,500 / Optional interest-free loan: applied to grant
A rural household combining the uplift across heating and efficiency measures can reach up to £18,000 in grant funding alone (mygov.scot, 2026). Note that solar PV on its own is not funded here; only solar PV-T hybrid and solar thermal qualify, and only as a loan. For standalone solar PV, point customers at the Smart Export Guarantee rates instead.
Who is eligible for the HES grant?
You can apply if the property is an existing home in Scotland and you are the owner-occupier, living in it as your only or main residence (Home Energy Scotland, 2026). The decisive point for installers is that you do not need to be on benefits to qualify. That separates the grant from means-tested support and opens it to ordinary owner-occupiers who would fail an income test.
There are conditions worth flagging early in a quote. A heat pump only qualifies if it provides 100% of the home's heating and hot water, so hybrid heat pumps are excluded. Replacement heat pumps get the loan but not the grant. And for energy efficiency work, the improvement must appear in the recommendations table of a valid Energy Performance Certificate before funding is approved.
The interest-free loan and repayment terms
The loan covers whatever the grant does not, at 0% interest, with repayment terms set by the amount borrowed. Loans under £5,000 run to five years, £5,000 to £9,999 up to ten years, and anything above £10,000 up to twelve years (Home Energy Scotland, 2026). A successful loan application carries an administrative fee of 1.5% of the loan value, capped at £150, and Energy Saving Trust runs affordability and credit checks before releasing funds.
One cash-flow detail matters on site. For renewable systems the homeowner can draw down up to 60% of the funding as a deposit against the material cost, released on a quote or letter from the installer. That deposit facility means you are not carrying the full material cost until final sign-off, which changes how you price the job.
It is worth setting expectations with the customer on timing too. Repayments only begin after the first payment is released, so a household is not servicing a loan while the job is still being installed. And because the grant and loan are not linked to other incentives, a customer can still register the finished system for the Smart Export Guarantee to earn from exported power, or look at a solar battery grant route separately.
Home Energy Scotland Grant vs Warmer Homes Scotland
Scotland runs two main domestic schemes and they serve different customers. The Home Energy Scotland Grant is open to any owner-occupier regardless of income. Warmer Homes Scotland is means-tested, delivered by Warmworks, and offers support worth £10,000 or more to households on low incomes or means-tested benefits with a poor EPC (mygov.scot, 2026).
- Income test: Home Energy Scotland Grant: None / Warmer Homes Scotland: Yes, low income or benefits
- Heat pump grant: Home Energy Scotland Grant: Up to £7,500 plus loan / Warmer Homes Scotland: Included in package
- Typical support: Home Energy Scotland Grant: Grant plus 0% loan / Warmer Homes Scotland: £10,000 or more
- Delivered by: Home Energy Scotland Grant: Energy Saving Trust / Warmer Homes Scotland: Warmworks
- Best for: Home Energy Scotland Grant: Owner-occupiers funding an upgrade / Warmer Homes Scotland: Fuel-poor households
If a customer is on a low income, screen them for Warmer Homes Scotland first, because it can deliver more with nothing to repay. For everyone else, the grant and loan is the stronger route. The ECO4 scheme also runs in Scotland and can be combined with other support in some cases.
What accreditation do installers need?
For any clean heating or renewable system funded by the grant, both the installer and the product must be certified under the Microgeneration Certification Scheme, with the sole exception of micro-hydro (Home Energy Scotland, 2026). There is no MCS workaround for heat pumps here; without it, the customer's application fails. If you are not yet certified, our guide on becoming an ECO4 installer covers the certification landscape that overlaps with these schemes.
For energy efficiency measures the rule is different. Solid wall, underfloor, flat roof and room-in-roof insulation must be installed by a business registered with TrustMark for that specific measure. Other efficiency measures carry no set installer requirement, though homeowners are advised to get three quotes and check trade accreditation. That split catches out firms that hold one credential but not the other, so confirm both before you promise a customer the funding will land.
How does the application process work?
The customer drives the application, not the installer, and the order of events is strict. They contact Home Energy Scotland on 0808 808 2282, get an advice call, and receive an emailed referral link within about two working days. They then submit the online form with an itemised quote from you and, for efficiency work, a valid EPC. Applications are processed within about ten working days (Home Energy Scotland, 2026).
The rule that catches installers out is timing. No work can start until the written funding offer is issued, because funding is never granted retrospectively. Once the offer arrives the customer has fourteen days to sign and nine months to complete the work and claim. In practice, a clear, itemised quote that names the exact MCS-certified product speeds the whole thing up, because the delivery team is checking your paperwork against the terms before they release a penny.
Common mistakes installers make with HES quotes
The most expensive mistake is letting a customer start work before the written offer arrives, because funding is never granted retrospectively and the job then falls outside the scheme entirely. On a busy schedule it is tempting to book the install as soon as the customer says yes, but the offer has to be signed first, within fourteen days of issue, and only then does the nine-month clock to complete and claim begin.
The second is quoting the wrong product. The delivery team checks your itemised quote against the terms before releasing a penny, so a heat pump that does not provide 100% of heating and hot water, or a hybrid system, will be rejected. Name the exact MCS-certified model and specify that it meets the whole-house requirement. Getting three comparable quotes is something Home Energy Scotland actively recommends to customers, so a clear, complete quote is also how you win the job against slower competitors (Home Energy Scotland, 2026). A consistent low-carbon quoting tool such as Reonic helps keep that paperwork the same across every job.
FAQ
Does solar PV qualify for the Home Energy Scotland Grant?
Standalone solar PV is not funded by the grant or the loan. Only solar thermal and solar PV-T hybrid systems qualify, and only as an interest-free loan of up to £5,000, not a grant. Customers wanting standalone PV should look at the Smart Export Guarantee for income on exported power and treat the panels as a self-funded upgrade rather than a grant-backed one.
Can you get the Home Energy Scotland Grant if you are not on benefits?
Yes. Unlike Warmer Homes Scotland, the grant has no income test. Any owner-occupier living in their main Scottish residence can apply, which makes it a much wider market. Benefits status only matters if you are also screening the customer for the means-tested Warmer Homes Scotland scheme, which can offer more support to low-income households.
How much is the rural uplift and who gets it?
The rural uplift adds £1,500 to both the heating grant and the efficiency grant. It applies to homes in remote rural areas, islands, and off-gas accessible rural areas as defined by the Scottish Government's Urban Rural Classification. A Home Energy Scotland adviser confirms eligibility. Combined across measures, it can lift total grant funding to as much as £18,000 for a qualifying rural home.
Do installers need to be MCS certified for the grant?
Yes, for heat pumps and other renewable systems both the installer and the product must be MCS certified, with the only exception being micro-hydro. For solid wall, underfloor and roof insulation the installer must instead be TrustMark registered for that measure. Missing the right accreditation means the customer's application will be rejected, so confirm it before quoting.
Can the grant be combined with an interest-free loan?
Yes, and that is the point of the scheme. The grant covers part of the cost and the 0% loan covers the rest, up to the funding limit for each measure. For a heat pump that means up to £7,500 as a grant and up to £7,500 as a loan. Repayment terms run from five to twelve years depending on the amount, with a 1.5% admin fee capped at £150.
