GreenVal demonstration

If you are, or thinking about, using Propflo below is a run through of our GreenVal energy efficiency retrofit tool that enables homeowners and landlords to review a property report, explore benefits and improvements, and get direct quotes from national accredited suppliers.


Below are some common questions related to the GreenVal tool.

We use a number of open datasets including Royal Mail, Ordnance Survey, Government EPC data as well as our own models.

The homeowner is presented with an estimated energy rating and recommended to get an EPC, but can also go on to explore typical improvements for properties like theirs and get quotes.

We’ve based this on a typical green discount rate from several lenders, the average loan amount in the UK, and an assumed 5 year deal.

Mortgage savings are not related to a particular lender unless clearly stated.

Our calculation treats estimated energy savings as increased disposable income and then applies a typical income multiplier.

This is an estimate based on the total costs of doing improvement works and what proportion of this spend could be claimed as part of capital gains tax or corporation tax minus any tax allowances.

We select improvement suppliers based on quality, holding relevant accreditations and warranties, and the degree of UK coverage. We have checked they hold these accreditations and appropriate insurances.

Suppliers may vary from time to time so for an up-to-date list of current suppliers please email

In order to keep the cost of our services low or free to homeowners we do take commission from some improvement suppliers and may split this with referral partners.
