The heat pump questions I hear most often aren’t really about heat pumps. They’re about doubt. People suspect the grant has hidden conditions, so they either skip it or ring five installers hoping one will say yes. Neither approach helps. Twenty quiet minutes at the kitchen table will tell you more than a week of sales calls.
Where Should You Actually Begin?
Begin with your Energy Performance Certificate (EPC). It’s free to look up on GOV.UK, and it decides more than most people expect.
Check the date first. Certificates last ten years, and the boiler upgrade scheme needs one that’s still valid. Then scroll down to the line describing your main heating. Does it match what’s in your house today? Older certificates sometimes list a system that was ripped out years ago. If yours looks wrong, a fresh assessment avoids awkward questions later. That usually costs between £60 and £120, which is cheap insurance.
The rating itself won’t count against you. An F-rated farmhouse can qualify just as well as a tidy new-build terrace.
Does Owning the Place Settle It?
Mostly, but not completely.
Owner-occupiers and private landlords can apply. Tenants can’t, although nothing stops you from forwarding this column to your landlord. Council and housing association homes sit outside the scheme entirely.
New builds are where people get caught out. If a developer built your home, you won’t qualify. If you commissioned it yourself as a custom build, you can. Buyers of nearly-new homes often assume they fall into the second group. Usually they don’t.
What Sinks Applications That Looked Fine on Paper?
Two things, and both come from the past rather than the present.
The first is earlier funding. If public money ever paid for a heat pump or biomass boiler at your address, that history usually blocks a new claim, even if a previous owner did the work. Your conveyancing pack may hold the answer. If it doesn’t, ask the seller’s agent before you assume anything.
The second is the urge to hedge. Many readers want the heat pump and the old boiler, just in case. I understand the instinct. The scheme doesn’t allow it. The new system must take over your heating completely, so decide early whether you’re comfortable with that.
Is £7,500 Really £7,500?
As a deduction, yes. As a saving, not always.
The air source heat pump grant comes off the bill as a fixed amount, so a bigger job doesn’t earn a bigger grant. Before you commit, ask every installer for two figures in writing: the full price before the grant and the balance after it. A firm that only shows you the second number is hiding something you need. Comparing pre-grant prices is the simplest way to spot a quote that has quietly crept up to absorb the discount.
Rates have changed during the scheme’s life, too. Check Ofgem’s current figure rather than trusting an old advert.
What Looks Simple but Isn’t?
Location. England and Wales qualify, while Scotland and Northern Ireland run their own support. Flats, listed buildings, and homes in conservation areas can still apply, but they may need consent from a freeholder or the local council. That paperwork moves at its own pace. Start it before you book surveys, not after.
Timing catches people out as well. If you plan to sell within a year or two, consider whether you’ll stay long enough to benefit. The grant follows the property, not you.
What Should You Have Ready Before an Installer Calls?
Keep it short:
- Your EPC date and reference number
- Twelve months of fuel or electricity bills
- A rough sense of where an outdoor unit could fit
- Any permissions you already know you’ll need
Then check the installer’s MCS certification on the MCS website. Without it, they can’t claim the grant for you, however polished their brochure looks.
Will It Be Worth the Effort?
That depends on what heats your home now. Households on oil, LPG, or electric heaters usually have the strongest case. If you’re on mains gas, ask for estimated running costs alongside the quote, and press for the assumptions behind them.
My advice is simple. Settle eligibility yourself, tonight, with your EPC and your paperwork. Save installers for the harder questions only they can answer.
