People tend to ring up about a heat pump once they have heard there is a grant going, and there is, that part is real. Home Energy Scotland will put money towards one if you own your home and live in it, and lend you the rest interest-free, which is the part that gets folk over the line, because what stops most people is finding the lump up front. The figures, since everybody asks: up to £7,500 as a grant towards the heat pump itself, and up to another £7,500 on top as the interest-free loan if you need it. Remote rural and island homes get an extra £1,500 on the grant, so up to £9,000, but most of Edinburgh sits on the standard rate, so do not pencil in a figure somebody up north quoted you. And read the up to, because that is a ceiling, not a cheque in the post. What you actually get comes back in your written offer, and the pot runs by financial year, April to March, while the money lasts.
The Boiler Upgrade Scheme is not a Scottish thing
If you have read about a £7,500 Boiler Upgrade Scheme grant, that is England and Wales only, and a house in Scotland cannot claim a penny of it. It is a UK Government scheme run by Ofgem. Ours is a separate one, the Home Energy Scotland Grant and Loan, Scottish Government money paid out through the Energy Saving Trust, and it has its own rules.
What makes this one so easy to fall into is that the two schemes look nearly identical from a distance. Both lead on £7,500. Both have a £1,500 uplift sitting on top. But the uplifts are for completely different things, and that is where folk come unstuck. Down south the extra £1,500 is for homes off the gas grid, on oil or LPG, and it runs to March 2027. Up here it has nothing to do with gas, it is your postcode, remote rural or island or off-gas-accessible rural on the Scottish Government's classification, and Home Energy Scotland checks it. So somebody in an oil-heated house on the edge of Edinburgh reads an English article, works out they are off the gas grid, and pencils in £9,000. They are not getting £9,000. They are on the standard £7,500, because Edinburgh is not a rural postcode.
Mind you, that line is drawn on the postcode, not on the map in your head, and it does not stop neatly at the city bypass. Once you are out through Midlothian and into the villages and the farm roads, there are addresses that fall inside the classification and others a mile down the same road that do not. I am not going to list postcodes at you, it is not a thing to be guessing at. If you are anywhere outside the city proper, put your postcode to Home Energy Scotland and get them to tell you which side of the line you are on before you budget for anything, because that £1,500 is worth a phone call.
It got easier to trip over in April 2026, when the Boiler Upgrade Scheme was extended to 2030 and widened to take in air-to-air units, the sort that blow warm air about rather than heating water. Those get money in England now. They get nothing here, Home Energy Scotland will not fund air-to-air at all, and it will not fund a hybrid either, what it funds is one system doing 100% of your heating and your hot water. So there is more current English content about heat pump grants floating around than there used to be, and next to none of it tells you which country it is for. If you are reading anything at all about a heat pump grant, the first thing worth checking is who it was written for. More on why the Boiler Upgrade Scheme does not reach Scotland.
The house is what really decides it
What I will spend longer on is the house, because that is the part that decides whether any of this is worth doing.
A heat pump does not get properly hot. Your gas boiler runs the water round at seventy-odd degrees and the rads are too warm to leave your hand on, a heat pump sits far cooler and heats the place slowly through the day, which only keeps you warm if the house is holding the heat in rather than pouring it out the walls and windows. A good chunk of Edinburgh is solid sandstone with no cavity to fill, so how the place is built is the first thing worth looking at, and it is the bit installers tend to skate past. The loft matters. And somebody has to work out how fast the house is losing heat, or you end up sizing a heat pump for a building that throws warmth away faster than the unit can replace it.
Your radiators are probably in on it too
Your radiators are probably part of it too. They went in to suit a hot boiler, and because a heat pump runs cooler you usually need bigger ones to push the same heat into the room at a lower temperature, often most of them, and that is money people never see coming.
Then there's the hot water
Hot water trips up the flats especially. A combi makes your hot water the second you turn the tap, and that is what is in most flats round here. A heat pump will not do that. It wants a cylinder, a proper tank somewhere, and then you are standing in a wee flat working out where on earth a tank is meant to live now the airing cupboard got pulled out the day the combi went in. I have seen that one detail end the conversation on its own.
A couple of things there's no shifting on
A couple of things there is no shifting on, mind. Whoever installs it has to be MCS-registered, and the kit as well, or the grant simply does not pay out. Nor is there grant money for swapping out a heat pump you already have, that is for first-time installs, though there can still be a loan in it. The other is timing, and it catches people, because the money has to be signed off before any work starts, so let a keen installer make an early start to get things moving and the grant for that house is gone. Folk genuinely do this, lose thousands to save themselves a fortnight. And the order matters, the survey and a rough price first, then the heat loss and the design, then it goes to Home Energy Scotland and you sit waiting on the offer, and only after that does a radiator get touched. All the hanging about is in that stretch. The fitting is a few days at the end.
When it's just not the right house
So I will be straight, it does not suit every house. Tenements are the awkward ones. Where does the unit even go, on a back wall four neighbours share, in a drying green that belongs to the whole stair, on the front of sandstone the council will not let you bolt anything to. Nowhere to put the thing is a flat no, and the centre of town is full of that exact problem. A cold draughty single-skin house is much the same, where bringing the pipework and the radiators up to the job would eat a small fortune. In a place like that the money is better going into the walls and the loft first, or into heating it some other way, instead of forcing a heat pump into a house that is not ready for one.
So, is it worth it?
They do work, and the grant and the loan bring the cost down to something very doable for a house that suits one. If you are in Edinburgh and thinking about it, get your eligibility checked, and get somebody honest round to look at the actual house before you spend anything.
If the house is off the gas grid, the decision is not just grant or no grant either. Oil, LPG and HVO all get dragged into it, so start with the wider off-gas heating choice before you let the funding headline decide.
Get in touch and you will get a straight answer, no patter.
Heat pump grant FAQs
The questions Edinburgh homeowners ask before they get started.
Up to £7,500 as a grant towards the heat pump, with up to another £7,500 available on top as an interest-free loan. Remote rural and island homes can claim an extra £1,500 on the grant, so up to £9,000, but most of Edinburgh is on the standard rate. It's a ceiling rather than a set amount, and it's a Scottish scheme — the Boiler Upgrade Scheme you'll see quoted is England and Wales only, so don't pencil in a number from an English article.
