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.
What’s the difference between an online assessment and a home assessment?
Online assessments use existing online data such as your home’s Energy Performance Certificate (EPC). Or if
isn’t available for your home, neighbouring properties will be used as a basis to determine your home’s
A home assessment involves an accredited assessor visiting you and your home to give an inspection, and chat

How much is a home assessment?
We offer two options - online only (you fill out our questionnaire and we use publicly available data to
home) or a visit from an accredited Retrofit Assessor.
Our pricing structure is simple:
- Online - £290 + VAT
- 1-2 bed £350 +VAT
- 3-4 bed £450 +VAT
- 5+ bed £600 +VAT
Do I need to be in for a home assessment?

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

- 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

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
- The problem areas observed by the Retrofit Assessor
- A breakdown of each recommended job, the associated cost and the time it will take, it lays out each job

Why should I get a Home Energy Plan?
The hardest part of making your home more energy efficient is knowing where to begin. Our plan gives you all
information you need to improve your home’s warmth, and reduce its emissions and running costs, like energy
Our plan shows you the current state of your home’s energy efficiency, it tells you what improvements could

How can I trust the Home Energy Plan is accurate?
The plan will be put together by our trustmark accredited assessors who are expertly trained and follow
regulations to the highest standard.
In the making of the plan we use BRE accredited software (so the industry standard) and regularly perform
quality assurance to ensure that all plans are fully accurate to the home’s they’re for.
What work do you carry out?
The retrofit work we carry out includes:
- Double and triple glazing
- Heat pump installation
- Cavity wall insulation
- External wall insulation
- Internal wall insulation
- Loft insulation
- Solar PV
- Underfloor heating
We also offer monitoring and aftercare to ensure your new energy efficiency measures are working to the best
How long does each job take?
It always depends on the type and size of your property, and occasionally the area you live in. But for a
house you can expect:
- Double and triple glazing: about 1-3 hours per window
- Heat pump installation: 2-3 days (most of this work takes place outside so minimal disruption in your
- Cavity wall insulation: 2-3 hours
- External wall insulation: 5-7 working days
- Internal wall insulation: 3-5 days
- Loft insulation: 2 hours
- Solar PV: 2 days (most of this is taken up by putting scaffolding up which is why it’s great to get this
you’re already having other work done).
- Underfloor heating: 1-2 days
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

What if I want to find my own contractors to complete the Home Energy Plan?
That’s absolutely fine, we want to give you as much flexibility as you want. We can let you source your own,
offer advice on who to pick if you want it, and we can provide all the contractors for the jobs. It’s up to
How do you ensure your contractors are reliable?

What grant funding might I be eligible for?
There are a number of grants and schemes available directly to members of the public (as well as to
organisations who then distribute money towards projects).
There are grants towards upgrading your boiler to a heat pump (Boiler Upgrade Scheme), there’s also the
Upgrade Scheme (HUG) if you earn less than £20,000 per year.
