How Much Does a Heat Pump Cost? 2026 Guide

If you are researching heat pump cost, the first thing to know is that there is no single flat price. The cost of a heat pump depends on the type of system, the size and layout of your home, and whether any upgrades are needed to help the system run properly.

For most homeowners, the main comparison will be an air source heat pump, as this is the most common option for UK homes. Ground source systems are available too, but they are usually much more expensive to install. The guide below breaks down what a heat pump can cost in 2026, what pushes the price up, what support may be available, and why the cheapest quote is not always the best value.

What does a heat pump cost in the UK?

For a typical air source heat pump, a useful 2026 guide price is around £11,000 to £13,200 installed before grants. Some homes will fall below that, while others will sit well above it if extra work is needed.

If you are looking at a ground source heat pump, costs are much higher. A typical installation can come in at around £29,000, and in some cases much more if drilling or major ground works are required.

That is why most homeowners start with air source systems. They are usually more practical, more common, and far easier to compare when you are pricing a heat pump for an existing home.

Typical heat pump cost by type

These are guide prices, not fixed package costs. A real quote may be lower or higher depending on the property, the specification of the system, and how much work is needed around the installation.

Why do heat pump quotes vary so much?

This is where many cost guides become too vague. You are not simply paying for the unit itself. You are paying for a heating system that has to suit the property.

The biggest factors affecting heat pump cost usually include:

• the type of heat pump

• the size of the property

• how much heat the home loses

• the existing heating setup

• whether larger radiators are needed

• the complexity of the installation

• the controls and hot water setup

• the make and model of the system

A smaller, well-insulated home with a simple layout is usually cheaper to convert than an older property that needs several changes before a heat pump can work properly.

That is why broad online guide prices are useful, but only to a point. The real number comes from assessing the home, not just the product.

What is included in the price?

A proper heat pump quote should reflect more than the outdoor unit.

Depending on the home, the total price may include:

• the heat pump itself

• installation labour

• controls and thermostat

• cylinder work if required

• pipework changes

• commissioning

• radiator upgrades in some homes

• removal or adjustment of older system components

This matters because one quote can look much cheaper than another on the surface, but may leave out work that is needed for the system to perform properly.

For homeowners, the better question is not just “what is the cheapest heat pump?” but “what is included in the quote, and will the system actually suit my home?”

How much does installation cost?

Installation is a major part of the total spend.

In some homes, fitting an air source heat pump is fairly straightforward. In others, the installer may need to change radiators, improve controls, alter pipework, or work around access and space limitations. That is often where the price moves.

With ground source heat pumps, installation costs rise sharply because the work is much more involved. Trenching, loop installation, or borehole drilling can become a large project in its own right.

That is why installation is not a minor add-on. It is one of the main reasons heat pump quotes can differ so much from one home to another.

What grants are available in 2026?

For many homeowners in England and Wales, the main support scheme is the Boiler Upgrade Scheme.

This scheme can take £7,500 off the upfront cost of an eligible air source heat pump or ground source heat pump installation. In practice, that can make a major difference to what you actually pay rather than what the headline quote says.

This is one of the biggest reasons heat pumps have become more realistic for a wider range of households. A system that looks expensive at first glance can become far more affordable once grant support is taken into account.

Eligibility and installer requirements still matter, so the grant should be treated as part of a proper quote process rather than a guaranteed deduction in every case.

What could you pay after the grant?

The grant does not make every system cheap, but it can change the conversation significantly.

Here is a simple example using guide prices:

These are example figures only, but they show why grant-backed pricing is far more useful than looking at the full system price on its own.

How much does a heat pump cost to run?

Upfront cost is only part of the picture. Running costs matter just as much.

A heat pump can be efficient to run, but savings depend heavily on the property and the system design. A well-installed heat pump in a suitable home has a much better chance of running efficiently than one fitted into a home that is not ready for it.

Running costs are influenced by:

• insulation levels

• heat loss

• electricity prices

• how the system is set up

• the temperature your home needs

• what heating system you are replacing

That is why blanket promises around savings should be treated carefully. A heat pump can work very well, but performance is closely tied to the installation and the home itself.

What about servicing and maintenance?

Heat pumps still need regular servicing and ongoing care.

While annual costs are much lower than the installation cost, servicing should still be factored into the overall picture. As a rough guide, many homeowners budget a few hundred pounds for professional servicing, depending on the type of system and the level of maintenance required.

A properly designed and maintained system is more likely to run efficiently and avoid issues later. That is another reason the cheapest upfront quote is not always the best long-term option.

Is a heat pump worth the cost?

For the right home, it can be.

A heat pump tends to make the most sense when:

• the home is reasonably well insulated

• the system has been sized properly

• the quote includes any necessary upgrades

• the homeowner is thinking long term

• grant support helps reduce the upfront cost

It may be less attractive where a property needs extensive changes before the system can perform well, or where the homeowner is comparing purely on lowest upfront spend.

The key point is that heat pump cost should not be judged on the unit price alone. What matters is the cost of a system that is right for the property and works properly once installed.

Getting a clearer air source heat pump quote

General guide prices are useful, but they only go so far. The real cost depends on your home, your current heating setup, and whether any supporting work is required.

That is where a more tailored quote becomes useful. For homeowners looking at air source heat pump installation with grant support, the next step is understanding what the property needs in practice, how the grant affects the final figure, and whether the system is being quoted properly rather than cheaply.

For iHeat, that is where the conversation becomes more useful than a generic online range.

A clearer quote should show not just the rough cost of a heat pump, but what is driving that price and what it means for your home specifically.
