Solarable is live — your roof's solar numbers, before you speak to anyone

Solar shopping in the UK has a quiet problem: the homeowner walks in last. You book a quote, an installer arrives with a tablet, and you're handed a number you have no way to sanity-check. We built Solarable to flip that around — so the data about your roof reaches you first.

As of today, Solarable is live. Type in your postcode and house number, and in under a minute you get an honest read on your own roof: which way it faces, how much sun it gets, the kind of system that fits, and a realistic benefit range. No account, no quote resale, no sales call. You decide what to do next — and who, if anyone, to call.

Here's what you can do right now.

Check your roof from a postcode

Enter your address and we place your home on the map, pull in the building's footprint, and work out which way each slope of your roof appears to face. It's the two-minute version of the first thing a surveyor does — except you're doing it yourself, for free, before anyone's in your diary.

Get a Solarable Report

The Report is the heart of it. You get a Solarable Score, the direction your roof appears to face, a plain-English suitability read, and the caveats that matter — all in one card you can keep or print. We deal in ranges, not false precision: "appears to face south-west" and "estimated annual benefit of £X–£Y a year," never a number pretending to be exact.

See your roof from above

Where coverage allows, we show your actual roof from above and shade it by how much sunlight each part receives across the year — the brighter slopes are the ones worth covering. East- and west-facing roofs do better than most people expect, and flat roofs are supported too. It turns "a satellite view" into "your roof, scored."

Run honest savings numbers

The savings calculator gives you an annual-benefit range and a payback range built on stated UK assumptions — energy price, export rate, how much you use during the day. Change the inputs and watch the range move. It's just the numbers, with every working shown — so you can trust the range instead of taking it on faith.

Find listed installers — you choose

When you're ready, you'll see MCS-certified installers who cover your postcode. We're a paid directory, not a lead marketplace: installers pay for a listing, and that's it. We don't resell your details, route managed leads, or take a cut of the job. You contact whoever you like, on your terms — and any featured listing is clearly labelled as paid placement.

Come prepared for quotes

This is the point of the whole thing. A solar quote goes very differently when you already know the shape of your own roof. By the time you book one, Solarable has handed you:

• The direction your roof appears to face — so you can tell whether a south-facing assumption actually applies to you.
• A rough sense of system size and how many panels realistically fit.
• An honest annual-benefit and payback range to measure any quote against.
• The Solarable Report itself, which you can print and bring to the conversation.
• A clear head about what's still a genuine estimate — because the on-roof survey is always the final word on suitability, shading, and exact figures.

Walk in with that, and you're no longer being sold to in the dark. You're checking a quote against what you already know. If a number looks off, you'll know to ask why — and our guide to questions to ask a solar installer covers the rest.

Solarable will never replace a proper installer survey, and we don't pretend to. What we can do is make sure you're the best-informed person in the room before one's even booked.

Start with your own roof — it takes about a minute, and there's nothing to sign up for.
