How much does a heat pump cost?

Our heat pumps start at £500 for a standard installation (including the £7,500 BUS government grant). All we need is a few details to generate a tailored quote for your home. We use the details you provide, as well as data from your home’s Energy Performance Certificate (EPC), energy usage, and other clever data sources, to calculate your fixed price.

We’re the largest installer of heat pumps in the UK and we’re obsessed with making heat pumps more affordable. We’ve invested £50 million to drive the rollout of heat pumps and push down costs (including building our own).

Heat pumps pair perfectly with smart tariffs like Cosy Octopus, so this one-time cost can unlock hundreds of pounds in savings every year. And going forward, replacing your heat pump will be as easy as replacing your boiler. Plus, heat pumps last up to 20 years, while gas boilers only last up to 15 years.

What does my heat pump include?

We do an in-person survey for every heat pump order to ensure everything is correct and confirm exactly what’s required. After the survey, we’ll update the quote to include any changes and explain them to you.

Our standard installation includes all radiator changes required to meet our design standard, which is to achieve a minimum Seasonal Coefficient of Performance (SCOP) of 3.0. This exceeds the Ofgem requirements to redeem the Boiler Upgrade Scheme (BUS) grant.

There should be no surprises during the installation - the price you pay will be the price in the installation agreement. The only exception is that if we discover a repipe is necessary at installation. (We do everything we possibly can to spot a repipe before we get to that point but it does happen!)

You can find out more about potential additional costs in the cost, grants and savings section of our Heat Pump FAQs.

Why is my quote higher than £500?

The work required during installation and the power of your new heat pump is based on the size and energy efficiency of your home, so the upfront cost can vary. We estimate about 10-15% of UK homes can get a heat pump from Octopus for £500 – these homes are usually newer, smaller, better insulated, have low energy usage, and require fewer big changes (like radiator swaps) to make the switch.

We’re committed to bringing down the cost of climate-friendly smart tech like heat pumps whilst making them an option for more homes. Most importantly, we want to make the choice between a heat pump or polluting fossil fuel heating a no-brainer. In the UK, the price of a new boiler (including installation) starts from around £1,500, whereas heat pumps start from £500.

Are heat pumps worth the investment?
