Community Solar UK: Group Buying, Cooperatives, and Shared Energy

Not everyone has to navigate solar alone. Several community-based routes exist in the UK that let you benefit from collective purchasing power, invest in shared local energy assets, or — in limited cases — trade surplus electricity with your neighbours. These models are often misunderstood or lumped together. This article separates them clearly, explains how each one actually works, and helps you work out which (if any) makes sense for your situation.

Three models, one label

The phrase "community solar" is used loosely to describe three quite different things:

1. Group buying schemes — households pool their interest so a council can negotiate bulk discounts with installers on their behalf
2. Community energy cooperatives — residents invest money in solar installed on shared buildings (schools, community halls, churches) and receive a financial return
3. Peer-to-peer energy trading — solar generators sell surplus electricity directly to nearby buyers rather than through the standard export route

Each model suits a different type of person and a different situation. The sections below cover each one in detail.

1. Solar Together — the group buying route

Solar Together is by far the most practical community solar option for homeowners who want panels on their own roof. It is a group purchasing scheme operated by iChoosr and typically run in partnership with local councils.

The idea is straightforward: if hundreds of households in a council area register interest together, the council can run a competitive tender and negotiate significantly better installation prices than any individual could achieve alone.

How the process works

1. Register interest via your council's Solar Together page — no commitment at this stage, just your name and some basic details about your home
2. The council runs a tender — installers bid competitively, with the registered households' data (roof types, approximate consumption) shaping the specification
3. You receive a personalised quote based on your specific address and estimated usage
4. Accept or decline — there is no obligation. You are free to compare the Solar Together quote with independent quotes and walk away entirely if you prefer
5. Installation is arranged if you accept — through the pre-vetted, MCS-certified installer selected in the tender

What to expect

• Typical saving: 15–20% below individual market quotes, thanks to collective purchasing power
• All installations are MCS-certified, which means they are eligible for the Smart Export Guarantee (SEG) and come with full manufacturer warranties
• Around 50 UK local authority areas participate — but coverage changes year to year, so always check your own council's current status
• Timeline from registration to installation: typically 3–6 months, longer than arranging your own installer but with much less effort on your part

Pros and cons at a glance

Solar Together is a solid option if you want a low-friction route and are comfortable with a single pre-vetted installer. If you want to compare quotes yourself or have specific requirements (a particular inverter brand, a tight timeline), going direct to the market may suit you better.

2. Community energy cooperatives

Community energy cooperatives are a fundamentally different model. Rather than getting solar panels on your own roof, you invest money in a solar installation on a community building — a school, sports club, church, or community hall — and receive a financial return from the energy it generates.

How cooperatives are structured

Community energy cooperatives are governed by the Co-operative and Community Benefit Societies Act 2014. You purchase shares in the cooperative — the minimum investment varies but is often in the £250–£1,000 range. The cooperative uses that capital to install and maintain solar on its host building.

Returns come from the electricity the installation generates: income is earned through the SEG export rate, private power purchase agreements with the host building, or direct grid sales. After costs, that income is paid out to shareholders — typically as an annual interest payment.

Well-established UK examples include:

• Brighton Energy Co-op — one of the country's longest-running community solar cooperatives
• Ovesco (Lewes-based) — solar on commercial and community buildings across Sussex
• Bath & West Community Energy — a diverse portfolio of renewable projects across rural England

Tax position

Shares in community energy cooperatives may qualify for EIS (Enterprise Investment Scheme) or SEIS tax relief in some cases, though not all cooperatives qualify — check directly with the cooperative and your own tax position. Some investors also hold cooperative shares in an Innovative Finance ISA, where the interest is received tax-free.

Grant funding in Scotland

Community solar projects in Scotland can apply for grant funding through CARES (Community and Renewable Energy Scheme), which provides planning-stage support from the Scottish Government. This makes Scotland particularly active for community energy cooperative development.

3. Peer-to-peer energy trading

Peer-to-peer (P2P) energy trading is the most technologically ambitious of the three models. In theory, it allows homeowners with solar panels to sell their surplus electricity directly to neighbours or nearby businesses — potentially at a better rate than the standard SEG export tariff.

In practice, P2P trading in the UK faces a significant structural barrier: Ofgem has not created a P2P licence category. All electricity retail in the UK requires a supply licence, so P2P platforms must operate within existing licence structures — either as an agent of a licensed supplier or through bespoke Ofgem sandbox arrangements. This regulatory constraint limits scale considerably.

UK operators in 2026

Approximately 300 UK communities had adopted some form of P2P energy arrangement as of early 2026, mostly small-scale pilots or local authority-backed projects.

Which model suits you?

How to find schemes in your area

Solar Together: Visit your local council's website and search for "Solar Together". iChoosr also maintains a list of participating councils at ichoosr.com. Note that schemes run annually — if your council is between rounds, you can register interest for the next one.

Community energy cooperatives: Community Energy England maintains a directory at communityenergyengland.org. In Scotland, the Energy Saving Trust's CARES page lists funded projects. Search for groups in your area and contact them directly to ask about current share offers.

P2P trading: There is no simple directory. UrbanChain's website explains their model. Otherwise, check whether your local authority has any pilot schemes underway.

A note on financial expectations

Community solar in the UK is not a get-rich-quick route. Solar Together saves you money upfront on an installation cost you would have incurred anyway. Cooperative returns of 3–5% per year are solid for an ethical investment but modest compared to higher-risk alternatives. P2P trading, where accessible, may improve your export rate marginally above the SEG.

None of these models changes the fundamental economics of solar dramatically — the core case for home solar is still self-consumption, reducing the amount of electricity you buy at around 24p/kWh (Q2 2026 standard flat rate). Community models add useful routes for those who can't or don't want to go through traditional channels.
