Retrofit

Retrofit Assessment & Coordination

A retrofit assessment looks at your whole home – its construction, condition, ventilation, occupancy and energy use – so improvements are planned in the right order and work well together.

Assessment and coordination – what's the difference?

Retrofit assessment

A detailed survey of your property and how it is used, recording the information needed to plan suitable energy improvements.

Retrofit coordination

Overseeing a retrofit project – from improvement options and medium-term planning through to sign-off – where a project or funding scheme requires it. Priced by personalised quote.

Not every project needs retrofit coordination. A standalone solar PV installation, for example, often doesn't. We'll tell you honestly whether it applies to you.
