What is your roof really worth?
We modelled over 15 million rooftops in the UK to put a number on the sunlight landing across the nation.
Free address check. Modelled estimates, not a quote.
Find your roof value
Pick your nation or district. These are modelled averages from the UK report. Your own roof is one free address check away.
What the report tells you that a sales quote won't
A number for your roof, not the country
Each modelled rooftop is rebuilt in 3D from satellite imagery, then sized to its angle, orientation and the local pattern of household electricity use. No national average applied to your street.
Even the lowest-ranked place pays
Scotland, the lowest-ranked UK nation, still models at £869 a year. Grey skies are not a dealbreaker.
Three options, side by side
Compare three system sizes and see the estimated returns on each before you speak to anyone.
From address to installer in three steps
Emily, EnergyBrain's roof assessor, does the first pass. She is an estimator, not a know-it-all: you confirm your roof and you choose.
Free assessment
Enter your address and confirm your roof on the map. You get a personalised rooftop value report: generation potential, battery benefit and payback.
Tailored design
Emily proposes three system and battery configurations and shows the estimated returns on each, so you can pick what suits how you use energy.
Installation
Emily suggests installers near you. Your chosen installer works with you to finalise the design and make it real.
Where sunlight pays most
Southern England and south-west Wales lead, but the spread is narrow, and every UK nation models above £800 a year in savings.
Modelled with GreenSketch rooftop data
EnergyBrain publishes the Roof Report. The rooftop modelling behind it comes from GreenSketch, the solar platform developed by OSW Group. Emily reads it back to you in plain words and says when she is estimating.

What is a Roof Report?
The estimated annual electricity bill savings a home could generate from an optimised rooftop solar and battery system. It's a way to see your roof's earning power as money you no longer spend. It is not paid income.
How are the numbers calculated?
Emily rebuilds each roof in 3D from satellite imagery, sizes a solar and battery system to the roof and typical household electricity use, simulates hourly generation and energy flows with PV-GIS data, then works out cost, savings, payback and returns.
Do the numbers include government support?
No. The UK figures do not factor in subsidies. Solar and batteries carry 0% VAT until 31 March 2027, and any grant you qualify for would improve the result.
Does solar really work in the UK?
Panels work in daylight, not only direct sun. In the UK report all four nations model above £800 a year in average savings: England highest at £954, Scotland lowest at £869.
Is this financial advice?
No. The report is for information only. Figures are indicative estimates based on stated assumptions and will vary by roof, tariff and system design. Get an installer's quote before you decide.
