The problem
You've asked an installer or two. The quotes vary wildly. You don't know if your home is actually suitable, whether you'd qualify for the government grant, or who to trust with a decision this size.
That confusion isn't your fault. Most of the information out there is designed to get you talking to a salesperson, not to help you decide. The numbers tell the story.

Why HeatPass is different
If a heat pump isn't right for your home right now, we'll tell you that clearly and with reasons. No inflated scores, no surveys designed to funnel you toward a sale.
When your home qualifies, you're connected with a single local MCS-certified specialist. One conversation, no competing calls, no feeling like bait in an auction.
Every installer we work with holds MCS certification. This is the government-recognised standard required to unlock the Boiler Upgrade Scheme grant.
What you get
Suitability rating
Green, Amber, or Red, with clear reasons. Green means a heat pump is a strong match for your home today. Amber means it's possible with some preparation. Red means we'll explain why and what your alternatives are.
BUS grant eligibility
We'll confirm whether your home and heating setup qualify for the £7,500 Boiler Upgrade Scheme and if not, exactly what's preventing it.
Estimated net cost
A realistic cost range for your specific home, after any applicable grant. Not a vague "from £X", but a range built from your property type, size, and current setup.
What needs doing first
If your home would benefit from insulation upgrades or radiator changes before installation makes financial sense, we'll say so and with an estimate of what that preparatory work would cost.
How it works

Questions
The BUS grant is a £7,500 government payment that reduces the upfront cost of installing an air source heat pump. It's paid directly to your MCS-certified installer and deducted from your quote, so you never see the money, but you do see the saving. To qualify, you must own your home, have a valid EPC with no outstanding cavity wall or loft insulation recommendations, and be replacing an existing fossil fuel heating system.
A typical air source heat pump installation costs £10,000–£18,000 before the grant. After the £7,500 BUS deduction, most installations land between £3,000 and £12,000 depending on property size, existing radiator setup, and whether a new hot water cylinder is needed. HeatPass will give you a personalised cost estimate based on your specific home, not a ballpark figure.
Most homes built after 1930 with some level of insulation are workable candidates. The key factors are outdoor space for the unit, the type of heating system you're replacing, and how well your home retains heat. Even properties with older insulation can work well if the heating circuit is sized correctly. Our checker will give you an honest assessment, including if the answer is no.
Not necessarily. Modern heat pump systems can run efficiently in homes with standard cavity wall and loft insulation. If your home has uninsulated solid walls, improvements are worth considering first, but they're not always a hard requirement. We'll tell you exactly what (if anything) your home needs before a heat pump makes financial sense, and give you an estimate of what that work would cost.
Air source heat pumps extract heat from outside air and are by far the most common type in UK homes. They sit outside the house and require no digging. Ground source heat pumps extract heat from the ground via buried pipe loops. They're more efficient but cost significantly more (typically £20,000–£35,000) and require substantial outdoor land. The BUS grant applies to both, but for most UK homes, air source is the practical and cost-effective choice.
