How long does a home assessment take?
A typical assessment for a 2-4 bedroom home can take from 2-3 hours to complete, depending on the size and
complexity of your home.
What happens during a home assessment?
A home assessment involves an accredited contractor spending 1-3 hours assessing your home and talking with you
about your priorities for the home.
They’ll then carry out the assessment known as the Reduced Standard Assessment Procedure (RdSAP). This looks at
how much energy your house is using to reach a specific level of heat. The assessor will also carry out a
ventilation report, to see how your house handles damp and the like The information they compile will go on to
form your Furbnow plan and details the jobs you need to be carried out, their cost, and the timeframes for
putting them in place.
Do I need to be in for a home assessment?
You do indeed. If you can allow for between 1-3 hours, some of which the assessor will need to chat to you
for that’d be ideal. The assessor will also need to access as much of the property as possible, for example the loft space and the cellar (if present).
The Assessor is on a data gathering mission. They are not (usually) the Retrofit Coordinator assigned to you, who will be able to answer all your technical questions.
Why is a whole house approach best?
A whole house retrofit it important because:
- It often works out cheaper. For example if the scaffolding is in place for solar panels you can leave it
external wall insulation meaning you only pay the once for two jobs worth of scaffolding.
- It’s better for the environment. Making retrofit changes to your house can often result in emissions from
itself as well as the release of carbon from the building materials. But by having workers only travelling
your house and combining certain jobs you can be sure to see a reduction in this.
- It’s less disruptive. Importantly it means you only have to have the installers in just the once, so you
month’s worth of work for a lifetime of lower bills and emissions. Rather than having them in and out of the
multiple times over the years.
Home Energy Plan
What’s in a Home Energy Plan?
- An overview of where your home is now in terms of bill costs and energy efficiency, and where it would be

What if I’m carrying out work with other contractors already?
This is actually ideal. We recommend you always get jobs done together which means the scaffolding is
