Unlocking the True Performance of Heat Pumps: Insights from Ofgem Data

March 04, 20252 min read

As the UK moves towards a greener future, heat pumps are becoming the go-to solution for efficient home heating. But how well do they really perform in real-world conditions? A recent report, In-Situ Heat Pump Performance Analysis of Ofgem Data (2017–2022), sheds light on just that—confirming what we at Neater Heat have always known: it’s all about the design!

Real-World Heat Pump Efficiency: Design is Everything

The report analysed data from thousands of installed heat pumps and found that, when properly designed and installed, they consistently deliver high efficiency. At Neater Heat, we know that performance starts with precision, which is why we carry out a full consultation and heat loss calculation before installation.

  • Building Fabric Assessment – We evaluate the insulation levels, window quality, and overall structure to determine how much heat a property retains.

  • Ventilation Losses – We check for potential heat loss through air exchange and factor this into our design.

  • Personal Heating Requirements – Every home is different, and so are its occupants! We take the time to understand how our clients use their heating systems to tailor the setup accordingly.

  • Property Location & Outdoor Conditions – We consider the local climate, expected outdoor temperatures, and site-specific factors to ensure the heat pump is designed to perform efficiently year-round.

With the right design and expert installation, heat pumps achieve a Seasonal Performance Factor (SPF) of 2.5 to 3.5, meaning they generate 2.5 to 3.5 units of heat for every unit of electricity consumed. Some well-optimised systems even exceed an SPF of 4, making them a game-changer for home heating!
