Measured Energy Performance

Measure the actual energy performance of your property with our non-invasive test that can be carried out with the occupiers inside. It’s perfect for:

  • Achieving net zero carbon targets
  • Measuring retrofit improvements
  • Verifying the energy performance rating of a property

Accurate and reliable data

Measured Energy Performance is a simple test that accurately measures the thermal performance of a property. It uses real-time information gathered from multiple data points to produce an energy efficiency rating that is precise and reliable.

Once we have analysed the data, we will provide you with a detailed report which compares your predicted/ As-built SAP EPC rating with a precise measured energy rating, along with expert analysis on how to improve your energy efficiency rating. You can view an excerpt of a sample report here.

Why is this important?

A performance gap can exist between design intent and the as-built performance of properties, known as the performance gap. In the largest study ever conducted this ‘gap’ was shown to be as high as 60%.

By accurately measuring thermal performance you can verify the energy rating of a property, accurately measure retrofit improvements and work towards net zero carbon targets armed with precise and reliable data.


Tackle fuel poverty
and meet net zero targets

With Measured Energy Performance you can:

Verify performance

Check your property is performing as promised.

Measure retrofit improvements

Compare how your properties perform before and after the installation of energy efficiency measures, and identify the most cost-effective combinations.

Identify underperforming properties

Identify properties with a poor thermal performance and effectively plan a co-ordinated retrofit plan with measurable outcomes.

Non-invasive and scalable

The assessment is performed with little intrusion and with the occupants still inside.

Small temperature sensors are placed around the house (usually on a book case or on top of a cupboard) which gather data over a 3 week period. Our expert team of energy consultants combine this data with weather and energy use information to assess how the house performs.
