How Much Does An Air Source Heat Pump Cost?

We know that it can be frustrating trying to find out a price for an Air Source Heat Pump as very few websites seem to explain it.

Here we attempt to give you the best possible explanation.

First, we’ll start by giving you an idea of what is involved. The actual Air Source Heat Pump itself can cost between £5,000 and £8,000 depending on the size and specification. However, that’s only part of what you’ll need for an efficient installation. The installation of an ASHP heating system is not simply a case of swapping your old Oil or LPG boiler for an ASHP as they work quite differently. An ASHP installation is a whole heating system upgrade.

Another important factor to consider when evaluating the cost of an ASHP installation is the amount you can get paid for having it installed! The Renewable Heat Incentive (RHI) is a government backed scheme that makes quarterly payments to homeowners that install ASHP systems. These payments can equal to anywhere between 30-80% of the installation cost! Compare that to installing a new Oil or LPG boiler, which does not receive any RHI payments and costs more to run, and an ASHP becomes a decidedly superior option.

Retrofitting

ASHP systems work at a lower flow temperature than traditional boiler systems. This means that the existing radiators and hot water cylinder will need to be upgraded for ones with larger surface areas to allow the heat generated by the ASHP to efficiently heat your home and hot water as efficiently as possible.

Ignoring this will result in an inefficient system that will cost a small fortune to run and will struggle to provide the heat to the home. As a result, upgrading the radiators and hot water cylinder is an essential part that needs to be factored into the overall installation cost.

It’s not just the materials that contribute to the cost of installing an ASHP, it’s also the labour element in carrying out the work. Depending on the size of the house and the number of radiators that need changing, the installation could take between 2 and 5 days. The existing pipework can be reused in most cases, once it has been flushed through and cleaned, but if it can’t, replacing it can also add to the cost.

Reusing the existing pipework infrastructure minimises upheaval, which means that in the majority of cases floorboards will not need to be pulled up to get to the pipework. That said, depending on the scope of the project, we can relocate radiators to different places in a room, or install underfloor heating or skirting board heating if that’s what you would prefer.

New Builds & Extensions

Installing an ASHP heating and hot water system during a new build or extension project is the perfect solution. The installation should be carried out during the first fix.

An ASHP is ideally paired with underfloor heating due to the larger surface area compared to radiators. We would carry out the installation of the underfloor heating system as well as the hot water system in this case.

For projects where the underfloor heating is to be embedded in concrete screed, the screeding would be carried out by the building contractor once the underfloor heating system has been installed. This would be separate to the cost of installing the ASHP.

extensions

There is an almost endless list of options for new builds and extensions, all of which have a bearing on the price.

In the case of an extension it could be that the new part of the house has under floor heating and the existing house upgrades to new, efficient and appropriately sized radiators. It is absolutely possible to mix and match between rooms or floors.

Price guide

Retrofit to a 4-bedroom house would start at around £12-15,000 inc 5% VAT for complete Turn-Key installation.

New build 4-bedroom house would start at around £15-18,000 inc 0% VAT for a complete Turn-Key installation.

Extensions would be somewhere between the two options above depending on the scope of works. VAT is charged at 5% for installations on extensions.

We do not send salespeople to your home but would send a technical assessor out to you once you’ve placed an order. The technical assessment is carried out to correctly specify the job and confirm that the price you have been quoted is accurate and correct.

For an accurate price and to discuss all the options available to you, please get in touch with us and we’ll be happy to run through everything with you over the phone or video call.
