In Summary: Air Source Heat Pump Installation Costs

Our air source heat pump (ASHP) installation cost guide is a long and detailed one. Don’t have the time to read it all now? Bookmark it for later and read this summary instead…

The cost of heat pumps tends to sit anywhere in the £1,495-£10,000 range. The kW power output, brand and specific model mean prices vary a great deal. 

For example's sake, a typical 3-bedroom house would use a unit such as the Vaillant aroTHERM Plus 7kW. Expect the Vaillant aroTHERM Plus to account for around £4,500 of the overall installation cost. 

Labour only will vary from £3,750-£7,000 depending on the complexity of the install, and the price of the heat pump. 

In the example of the Vaillant aroTHERM Plus 7kW, you’d see an overall heat pump installation cost of £10,380. However, if eligible for a government grant you could save up to £7,500, meaning the total cost to you is just £2,880 (with finance available).

Like anything in life, you get what you pay for; buying cheap and unreliable brands isn’t cost effective long-term. 

Typically, we’d suggest buying a heat pump from leading brands such as:

• Grant
• Daikin
• Vaillant
• Samsung
• Ideal

Detailed Air Source Heat Pump Installation Cost Guide

Below we’ve split cost estimates into two categories:

• The expected cost of an air source heat pump (pump unit only)
• The estimated cost of getting a heat pump installed (labour only and total price)

Air Source Heat Pump Prices

So, how much does an air source heat pump cost? Prices typically range from £1,495-£10,000. 

There are dozens of variables that affect the price of the heat pump you need including: size, warranty, brand and more.

The biggest variable that affects heat pump prices is the kW output. The higher the output, the more expensive that particular heat pump is going to be. So, a small 1-bedroom flat is going to need a lot smaller kW unit than a commercial property, and therefore, be much cheaper overall to install.

The majority of properties in the UK would use a heat pump sitting somewhere in the 4kW-16kW range. If we take something in the mid-range we’d be looking at a property such as:

• 3-bedroom semi-detached house
• Usually occupied by 2-4 people
• Space for a heat pump to be fitted in the garden
• Broken combi boiler, currently fitted in a kitchen cupboard

For this type of property / installation, you’d be looking at a 7kW air source heat pump; an ideal one being something like the Vaillant aroTHERM Plus 7kW. 

Prices for this Vaillant 7kW ASHP tend to sit in the £4,400-£4,650 range (pump unit only), depending on what deals are currently available from retailers.

In comparison, a combi boiler from Vaillant for the above property is likely to be £1,500 (unit only). But with a combi boiler, you won’t get huge energy savings, and it’s unlikely you’ll get government grants to cover the cost of fitting either.

Cost of Air Source Heat Pump & Installation

The bigger question really is, how much does air source heat pump installation cost? 

Heat pump installation costs tend to sit in the range of £3,750-£7,000 (labour only). 

Including all materials, expect a heat pump to cost a minimum of £7,000 (labour and materials). 

Taking an average, heat pump installation costs in the UK sit in the £7,000-£12,000 range.

Again, this is an estimate. Dozens of variables affect which heat pump you need, the complexity of the installation and therefore, the overall cost. 

If we take the same example above (3-bedroom property), using this clickable heat pump form we come up with the Vaillant aroTHERM Plus 7kW being the most suitable ASHP. Vaillant is a top of the line heating brand; a leader in innovation for both the combi boiler and air source heat pump markets.

The cost of installation here is a total of £10,380. But…and it’s a big BUT! The cost of pump installation is slashed to under £3,000, thanks to the £7,500 of government grants we’re able to get on your behalf!

What’s Included in ASHP Installation Costs

When comparing heat pump quotes, it’s important to read exactly what’s included. 

Everything from the quality of the heat pump, warranty and extras such as pipework, controls, cylinder installation and removal of your old unit, all affect the overall fitting cost. 

At Dwellow, we offer a complete service that includes: 

• Quality heat pump from a leading brand
• Workmanship warranty
• Hot water cylinder installation
• Radiator upgrades (where necessary)
• Pipework upgrades and suitable heating controls
• The recycling / removal of your old boiler

Heat Pump

The heat pump makes up the majority of the installation cost. Buy a cheap heat pump with a short warranty? Likely you’ll save some cash upfront, but pay the price in the long term. Fixing unreliable heat pumps isn’t cheap. 

Included in your heat pump installation cost will be the most suitable unit from a leading brand. We fit heat pumps from the following brands:

• Grant
• Daikin
• Vaillant
• Samsung
• Ideal

The best heat pump brands like the ones mentioned above, offer up to 7-years warranty on their units!

As each property’s hot water demand, heating demand, size and available installation area differs so much, the specific heat pump suitable will vary from property to property.

Use our 2-minute clickable heat pump installation cost tool, and get a fixed prices on-screen for the most suitable heat pumps for your property.

Workmanship Warranty

When comparing prices for heat pump fitting, it’s not just the pump warranty you should focus on. Not all MCS installers provide a workmanship warranty. And, if incorrectly fitted, their work could void your heat pump warranty too!

At Dwellow, not only do we offer an extensive manufacturer’s warranty, we also stand by our own work; as part of the cost of your heat pump installation, you’ll get a free 12-month workmanship warranty too.

Hot Water Cylinder

Heat pumps don’t work like combi boilers that heat water on demand. They take the “slow and steady” approach and therefore, need a hot water cylinder. When comparing heat pump installation costs, it’s important your installation quote includes a cylinder and labour for the cylinder’s installation. 

Of course, when you use our heat pump installation cost tool, all the fixed prices you see on screen include the most suitable hot water cylinder to work with your ASHP.

Radiator Upgrades

Air source heat pumps work by heating slowly and steadily. If you’re running old and inefficient radiators, they’ll need to be upgraded to maximise the efficiency of your heat pump. 

Not sure if you need a radiator upgrade? Our clickable form which takes 2-minutes to complete will determine whether you do or not. And if you do, your radiator upgrade will be included in the fixed price you see on-screen.

Pipework & Controls

Whether it’s upgrading pipework to work more efficiently with your new system, or heating controls to make your system work at full-tilt, we’ll include all necessary pipework and controls in your installation cost.

Removal / Recycling of Old Units

Depending on the complexity of the installation, we may need to remove: 

• Pipework
• Old fittings
• Radiators
• Your old boiler

As part of any heat pump installation price quote you get using our clickable form, this removal / recycling service comes free!

Air Source Heat Pump Grants

Any heating system upgrade is expensive. 

The good news? The government is committed to drastically reduce emissions in the UK, and offers air source heat pump grants that can help fund the majority of the installation cost. 

With Government grants, heat pump installation finance and huge energy / cash savings on offer, getting a heat pump fitted is becoming more and more cost effective each year. 

The majority of grants come from the Boiler Upgrade Scheme which you can read about here. Or, you can use our clickable form here to get your fixed price on-screen now.

As you can see from the example quote we got earlier via the Dwellow installation cost tool, you could save as much as £7,500 on the cost of a heat pump using a Government grant!
