What Is a Retrofit Assessor?
A retrofit assessor plays a key role in improving the energy performance of UK homes. By inspecting properties, assessing their energy use and reporting on how to make them more efficient, assessors help deliver upgrades like insulation, ventilation and heating improvements.
These recommendations follow the PAS 2035 guidelines, an official framework that underpins all modern retrofit projects in the UK. Qualified retrofit assessors are essential to national energy-saving schemes such as:
-
The Great British Insulation Scheme
-
ECO4 (Energy Company Obligation)
-
Local Authority Delivery funding
-
Home Upgrade Grants
As the UK accelerates toward net zero, retrofit jobs are expected to increase rapidly over the next 5 to 10 years.

There’s a growing demand across the UK for skilled professionals who can deliver on retrofit projects. With more than 29 million homes in the UK needing some form of energy upgrade, the industry urgently needs trained assessors.

The average salary for a retrofit assessor in the UK ranges between £30,000 and £50,000, with many opportunities for progression.
