Can You Install a Heat Pump in an Older Property?
24 August 2026 · 3 min read · by the PlumbGas team
There’s a big misconception that only modern properties can benefit from a heat pump. This simply isn’t true, and with the right design and installation, many older properties can also take advantage of this energy-efficient choice.
Here at PlumbGas Services Ltd, our heat pump installers are RECC and MCS registered to install heat pumps to industry safety requirements, and are backed up by multiple five-star reviews.
Whether you own a rustic barn or a Victorian terrace, the right support can help it become a highly efficient and eco-friendly home for the future, while still never losing its character. In this article, we’ll take a closer look at how to install a heat pump in an older property.
What Is a Heat Pump?
A heat pump doesn’t create heat, and instead moves it, drawing in air from the outside to the indoors for the colder months, and doing the opposite in summer. They deliver 300% to 400% efficiency, compared to the 90% efficiency of gas boilers.
The system also sidesteps the need to burn fossil fuels, making it an eco-friendly choice to reduce a household’s carbon footprint.
Can You Install a Heat Pump in an Older Property?
The persistent myth that only new-build properties can reap the rewards of a heat pump is incorrect. With the correct design approach, heat pump installation in older properties is entirely feasible.
Essentially, the system design methodology matters far more than the brand. For example, we use Heat Geek to install heat pumps in poorly insulated houses and older properties. Under the design principles of Heat Geek, installations in older homes can enjoy seasonal efficiencies of up to 500%, showing that any property can achieve outstanding results.
The Importance of a Heat Loss Survey
A successful installation in a period home relies on accurate calculations. This can only be achieved through a room-by-room heat loss survey. Here at PlumbGas Services Ltd, we provide completely free and comprehensive assessments to analyse your heat loss.
During a heat loss survey , our inspectors will take a look at:
- Property size and layout
- Existing insulation levels
- Pipework and water cylinder compatibility
- Radiator suitability
- Hot water demand
- Occupancy levels
Once the survey is completed, we can determine exactly what heat pump size your property requires.
We will also advise on expected running costs, whether any radiators will need upgrading for the project, and if any other features in your old property need to be updated to ensure your home is compatible with the heat pump system.
Maximising Efficiency and Offsetting Costs
Whether you own a contemporary or older property, there is a generous £7,500 government grant available towards the cost of a heat pump. This is offered under the Boiler Upgrade Scheme (BUS) for people who are switching to low-carbon heating systems for their property in England or Wales. Grants can even extend to £9,000 if you’re switching away from LPG or oil systems.
Here at PlumbGas Services Ltd, we are MSC-accredited and can handle the entire Ofgem application on your behalf, deducting it directly from the upfront cost.
To further enhance cost savings in the future, you can also pair the heat pump system with solar PV or switch to smart tariffs, as electricity will be needed to power the heat pump. These routes can give around £250 of annual savings, and disconnecting from the gas grid entirely can also save you roughly £135 in standing charges each year.
What Is the next Step?
If you want to future-proof your older property, we can help you take the first steps. All installations must be carried out by MCS-certified installers, such as the PlumbGas Services Ltd team.
