Easily improve your EPC Rating, increasing your properties value

As of April 2024, changes to the EPC software (rdSAP 10) could make a surprisingly simple step significantly more impactful for property owners: Introducing the ability to input a measured Air Tightness Test result.

What Does This Mean for You?

In short – you could improve your EPC rating by 1–3 points just by carrying out a professional air tightness test. Why? Because the new system allows assessors to use your actual measured air leakage rate, rather than relying on a conservative assumed value. This small change has the potential to:

• Boost your EPC rating quickly and affordably
• Increase your property’s market value by up to 20%
  
  

   

  

With the upcoming legislation aiming for all rental properties to reach a minimum EPC Band C by December 2028, this is the perfect opportunity to stay ahead. A small investment in air tightness testing could save you thousands compared to larger retrofits like new insulation or heating systems.

The Cost of Traditional Improvements

According to industry research, bringing a property from:

• Band D to Band C: Estimated cost ~£5,500
• Band F/G to Band C: Estimated cost £10,000–£12,000

Compare this with an air tightness test – a fast, non-invasive, and cost-effective option that may help gain 1–3 EPC points without major refurbishment work.

Don’t Let Cost Be a Barrier

In a recent report by Knight Frank, more than one in three landlords and homeowners cited cost as the main reason for avoiding EPC improvements. But air tightness testing offers a smart, affordable solution to overcome that hurdle and enhance your property’s long-term value.
