Retrofit Assessments

A Retrofit Assessment is a detailed analysis of an existing building aimed at identifying the most impactful energy-saving upgrades, helping you improve thermal performance, reduce emissions, and lower utility costs.

What you need to know.

1) What is a Retrofit Assessment?

A Retrofit Assessment provides an in-depth review of your building’s current performance, pinpointing areas where modern energy efficiency measures—like insulation, heating upgrades, ventilation systems, or renewables—can offer real savings. It's ideal for homeowners, landlords, developers, and housing associations looking to retrofit existing properties.

2) Who Needs One?

You should consider a Retrofit Assessment if you are:

  • A homeowner or landlord planning upgrades

  • Part of a renovation, extension, or conversion project

  • Managing multiple properties (e.g. lettings, social housing)

  • A developer aiming for higher EPC ratings post-upgrade

3) What’s Included in the Assessment?

Our Retrofit Assessments cover:

  1. Site visit & tangible survey – we examine fabric, heating, ventilation, lighting, and construction details

  2. Thermal imaging and leak detection – to find hidden insulation issues

  3. Energy modelling – to predict savings under different retrofit scenarios

  4. Customised recommendations – prioritised by payback period, cost, and impact

  5. EPC improvement estimates – helping you forecast the upgrade to your certificate rating

4) Why Choose a Professional Assessment?

Accurate baseline – no guesswork, just measured data

  1. Tailored roadmap – bespoke recommendations based on your building

  2. Better ROI – know which upgrades deliver real value

  3. Stronger planning – builds confidence for planning applications or grant applications
