Is a heat pump worth it?

If you are weighing up a heat pump, you want an answer, not a sales pitch: is it actually worth it? For most UK homes it is, once the government grant is factored in, and the case is strongest if you are coming off oil or LPG. But "worth it" depends on your home, your current fuel and how long you plan to stay, so here is the full picture, with the numbers behind each part, so you can decide rather than take anyone's word for it.

The short answer

A heat pump is worth it for most homes once the £7,500 government grant is applied, and clearly worth it for homes on oil or LPG, which can now claim £9,000 and usually save more on running costs. You get running costs that are level with or below a gas boiler, a steadier and quieter kind of warmth, more than three times the efficiency, and a system that should last around 20 years. The main thing weighing against it is a higher upfront cost than a straight boiler swap, though the grant narrows that gap and the price covers a whole-system upgrade, not just a new heat source.

Is a heat pump worth it financially?

For most homes the money case is sound once the grant is in, and it is at its strongest off mains gas. Here is how it breaks down.

Running costs. On a standard electricity tariff, a well-installed heat pump costs roughly £900 a year to run for a typical home, against about £960 for a gas boiler, on current figures from Nesta and the Energy Saving Trust. That is about level. On a specialist heat-pump electricity tariff the heat pump usually costs less, and if you are coming off oil or LPG it is normally cheaper to run either way, because those fuels already cost more per unit of heat.

The grant. The Boiler Upgrade Scheme takes £7,500 off the cost of an air source or ground source heat pump in England and Wales, deducted from your quote by your installer. From 21 July 2026 to 31 March 2027, eligible off-gas-grid homes on oil or LPG can claim £9,000 instead. There is no equivalent grant for a new gas boiler.

The upfront cost. This is the real trade-off. A heat pump typically costs £8,000 to £14,000 before the grant, against £2,500 to £4,000 for a like-for-like boiler swap. That is not a straight comparison, though: the heat pump price usually covers a hot water cylinder and any pipework or radiator changes your home needs, not just the heat source, so you are getting considerably more for the money. After the grant the gap narrows, and over a system that lasts around 20 years the sums often work in the heat pump's favour. Our guide to how much a heat pump costs breaks the numbers down in full.

Is a heat pump worth it for comfort and everyday life?

Where the running-cost case is close, day-to-day comfort often settles it. A gas boiler heats in short, hot bursts; a heat pump runs at a lower, steadier temperature for longer, so your home stays evenly warm rather than swinging between warm and cool. Most people find it a more comfortable kind of heat once they are used to it.

It is quiet, too. A modern air source unit runs at around 40 to 50 decibels outside, roughly the level of a quiet fridge, and you will not hear it indoors. There is a lower-carbon upside as well, since a heat pump runs on electricity rather than burning fuel in your home, though for most people that sits alongside the money and comfort rather than deciding it.

What owners actually say

The strongest evidence that heat pumps are worth it comes from the people who have them. In Nesta's large UK user survey, more than 80% of heat pump owners were as satisfied or more satisfied with their heat pump than with the heating system it replaced, and that held across property types, including older and Victorian homes. Owners were slightly less satisfied with the controls at first, which is a short learning curve rather than a lasting complaint, and a good installer sets the system up and shows you how it runs.

When a heat pump is clearly worth it

A few situations make the decision easier.

• You are on oil, LPG or an old, inefficient system: this is where the case is strongest, on both running costs and the higher off-grid grant.

• You are staying put for years: the longer you keep the home, the more the lower running costs and 20-year lifespan pay back the upfront cost.

• You are renovating or building: it is far cheaper to design in a heat pump and the right radiators from the start than to retrofit later.

• You want steadier, quieter warmth: where the running-cost case is close, the everyday experience often tips it.

When it is worth pausing

Being straight about it: a heat pump is not always the obvious call. If your gas boiler is new and working well, there is no need to rush, though it is worth planning your next replacement around a heat pump given the grant on offer now. If you have no suitable outdoor space, or you are about to move, the sums are harder to justify. The only way to know for certain is a proper heat-loss survey, where an engineer measures how your home loses heat and designs a system around it. For a fuller side-by-side, our guide to heat pump vs gas boiler weighs the two in detail, and our heat pump pros and cons covers the trade-offs honestly.

Frequently asked questions

Is a heat pump really worth it in the UK?
For most homes, yes, once the £7,500 grant is applied, and clearly so for homes coming off oil or LPG, which can claim £9,000 and usually save more on running costs. You gain running costs level with or below a gas boiler, steadier warmth, higher efficiency and a longer life. The main trade-off is a higher upfront cost, which the grant reduces.

How long does it take for a heat pump to pay for itself?
It depends most on the fuel you are leaving. Coming off oil or LPG, the running-cost savings and the higher £9,000 grant make the payback quicker. Coming off mains gas, running costs are closer, so the value comes more from the grant, the comfort and the longer lifespan than from a fast cash payback.

Is a heat pump worth it for an old house?
It can be. Nesta's survey found owners of older and Victorian homes were as satisfied as owners of newer ones. Older homes sometimes need larger radiators or better insulation to run efficiently, which a heat-loss survey will identify before you commit.

Are heat pumps cheaper to run than a gas boiler?
On mains gas, running costs are close today on a standard tariff, and usually lower on a specialist heat-pump tariff. Coming off oil or LPG, a heat pump is normally cheaper to run.

How long does a heat pump last?
A well-installed heat pump typically lasts around 20 years or more, longer than the 12 to 15 years of a typical gas boiler, which is part of why the upfront cost pays back over time.
