Solar Together: group buying that actually moves the price

Not free panels — cheaper panels, bought with the negotiating weight of thousands of neighbours behind you. Solar Together is the council-partnered group-buying programme operating across much of England, and in a post-ECO4 world it is one of the few mechanisms that reliably cuts the headline cost of going solar.

How a round works

Participating councils invite residents to register interest — free, with no commitment. Registrations are pooled and put to a reverse auction in which pre-vetted installers bid for the whole block of work. The lowest credible bidder wins, and every registrant receives a personal recommendation priced at the auction rate for their roof, based on the details they registered. You then have a window — typically several weeks — to accept, ask questions, or simply walk away.

The mechanism matters more than the marketing. An installer bidding for several hundred installations in one county can price each job with thin margins and zero customer-acquisition cost — the two fattest line items in a normal domestic solar quote. That is why group-buy pricing routinely undercuts comparable individual quotes by a meaningful double-digit percentage, with the exact gap varying round by round.

What you give up, honestly

Choice, mainly. You get the winning installer, the panel and inverter range they bid with, and the scheme's timetable — installations follow the acceptance window, so if your roof needs doing next week, this is the wrong queue. Bespoke requirements (in-roof panels, unusual roof coverings, complex scaffolding) sometimes price poorly through the standardised survey model. And while scheme installers are vetted and the framework includes consumer protections, you should still run the same checks you would on anyone: MCS certification, insurance-backed warranty, references.

None of that is disqualifying. The sensible play is to treat the Solar Together recommendation as one of your three quotes, alongside two independent MCS installers. If the group price wins on like-for-like kit — it often does — take it with confidence.

Stacking it with everything else in 2026

Group buying stacks cleanly with the rest of the live support. The auction price already reflects 0% VAT, which runs to 31 March 2027. Once installed, you choose a Smart Export Guarantee tariff like any other solar household. And if you are also replacing oil or LPG heating, the £7,500 Boiler Upgrade Scheme is unaffected by how you bought your panels. Batteries are usually offered within rounds too — often the most discounted line on the recommendation, since battery margins in the open market remain generous.

Finding a live round near you

Rounds open and close by council area through the year, so the honest answer to "is one open near me?" is "it depends when you ask". Check your county or district council's website for "Solar Together" plus the council name, or register on the programme's own site to be notified when your area opens. If your council has never participated, neighbouring authorities' schemes won't cover you — but our eligibility check will flag a live round where we know of one covering your postcode, alongside everything else you qualify for.
