Eight acronyms. Thousands off your bill.
We cross-reference every grant, tariff, and allowance your property qualifies for — the ones you've heard of, and the handful you haven't. Here are the big ones.
From survey to savings in four steps.
No jargon, no cold calls. We do the boring bits — paperwork, eligibility, installer vetting — so you can get on with the upgrade.
Tell us about your property
A 3-minute survey captures your setup, usage, and goals — no invasive paperwork.
We match the schemes
Our system cross-references every grant and tariff you qualify for — and the switching tariffs that beat yours.
Compare vetted installers
Transparent quotes from accredited installers — MCS, TrustMark, NAPIT. No tyre-kickers.
Install and start saving
We handle paperwork and grant claims. Bills drop from day one.
Every technology, tuned to your property and budget.
We don't sell hardware. We unlock the right mix of tech, tariffs, and funding for your situation — then connect you to the people who can install it properly.
Cut your bill this month — before a single panel goes up.
Energy switching is the quick win. We match your usage shape — EV charging, solar export, heat pump cycles — to the tariff that actually beats yours. No admin. Auto-renews to whatever's cheapest each year.
The average Decarbr customer who switches supplier saves this much in year one. EV & solar households usually save more.
Your roof is an income stream. We just price it properly.
From retail parks to light industrial, we model the install against full expensing, PPA finance, and your usage curve — so the payback is a spreadsheet, not a sermon.
Every installer is vetted, accredited, and rated.
1,800+ installers on the network. Each one passes our accreditation, insurance, and reference checks. Ratings update after every job.

Most UK homes qualify for at least two: the Boiler Upgrade Scheme (up to £7,500 toward a heat pump) and the Smart Export Guarantee (paid per kWh for solar you export). Lower-income homes and low-EPC properties often qualify for ECO4 or GBIS, which can cover insulation in full.
Comparison sites pick the cheapest static tariff. We match tariffs to your usage shape — EV charging windows, solar export, heat pump cycles — and auto-renew you each year without you having to lift a finger.
Every installer on our network is MCS, TrustMark, or NAPIT accredited for the work they quote for. We check insurance, recent references, and track ratings after each job. We remove installers who drop below a 4.6 rolling rating.
Solar: 1–2 days. Heat pump: 2–4 days (with a survey beforehand). Insulation: a single day for loft or cavity; 3–5 days for external wall. We'll tell you before you book.
For installs, you'll need your landlord's consent (we have a letter template). For energy switching, no consent needed — the supplier relationship is yours.

Free, no obligation. We'll match your property to every scheme, tariff, and grant you're entitled to — and connect you to vetted installers. Keep everything we find. Walk away any time.
