Compare lease, asset finance and cash routes alongside PPA on the commercial solar finance hub.
UK solar Power Purchase Agreements are offered by specialist rooftop funds, energy-supplier corporate-PPA desks, utility-scale developers and infrastructure funds — each suited to a different system size and structure. This is an independent map of the market and how to choose the right provider for your site. We are a provider-neutral matching layer, not a provider.
In the UK, corporate solar PPAs are offered by utility-scale developers and independent power producers (such as Lightsource bp, Ørsted, RWE and Statkraft), by energy-supplier corporate-PPA desks (EDF, Engie, Centrica Business Solutions, SmartestEnergy), and by specialist rooftop funds (Atrato, Foresight, NextEnergy) for smaller on-site deals. Typical terms run 10–25 years at a fixed or RPI-linked p/kWh tariff, usually requiring an investment-grade or guaranteed off-taker.
The named companies below are examples of who is active in the UK market for each provider type — they are market reference, not endorsements, partners or clients, and no ratings are implied.
| Provider type | Typical deal size | Structure | Term | Examples active in the UK |
|---|---|---|---|---|
| Specialist commercial rooftop solar funds Fund and own the PV system on your own roof or land and sell you the kilowatt-hours. The most common route for sub-5 MWp commercial off-takers and the typical match for a single-site on-site PPA. |
100 kWp – 5 MWp | On-site / behind-the-meter PPA | 15–25 years | Atrato Onsite Energy, Foresight Group, Bluefield, NextEnergy Capital, Aura Power |
| Utility & energy-supplier corporate-PPA desks Supply or 'sleeve' renewable power to your meters via a licensed supplier, balancing and shaping the generation. The usual route for tenants without roof rights and multi-site portfolios. |
1 MWp – utility scale | Sleeved / utility-route PPA | 10–15 years | Statkraft, Centrica Business Solutions, EDF, Engie, SmartestEnergy, Axpo |
| Independent power producers & developers (utility-scale) Build and operate utility-scale solar farms and contract the output directly to a single large off-taker. The route behind most headline corporate PPAs and the typical match for a virtual/synthetic PPA. |
5 MWp – 100 MWp+ | Corporate PPA (physical or virtual) | 10–20 years | Lightsource bp, Ørsted, RWE, Anesco, British Solar Renewables, Voltalia, Enviromena |
| Infrastructure-fund-backed SPVs Pools of institutional capital that fund solar through special-purpose vehicles. Strong for long-tenor, aggregated multi-site programmes where covenant strength matters. |
500 kWp – 20 MWp | On-site or aggregated multi-site PPA | 20–25 years | Greencoat Capital, Octopus Energy Generation, Gresham House, Downing |
| Broker / advisory & matching layer Independent advisers who explain the mechanics, set realistic tariff expectations and introduce off-takers to vetted providers — paid a disclosed referral fee on completion, with no provider commission bias. This is what SPPA is. |
Any (introducer) | Provider-neutral introduction | n/a | Solar Power Purchase Agreements (this site) and other independent advisers |
Tariff, term and covenant requirements vary by site. We match your profile to the provider type — and the specific providers — most likely to be competitive for you.
Choosing a provider is really about matching four things — structure, size, covenant and track record. The five steps below are how we shortlist on every introduction.
We are an independent editorial advisory and introducer (operated by SEO Dons Ltd) — we are not a provider, supplier or installer. We map your site to the provider types above, shortlist 3–5 specific providers most likely to be competitive for your sector, size and postcode, and return an indicative tariff. We are paid a flat referral fee on a completed deal, disclosed in writing before any introduction; we take no provider commission, so the shortlist is matched to your site, not skewed toward whoever pays most.
UK solar PPAs are provided by four broad groups: specialist commercial-rooftop funds (Atrato, Foresight, Bluefield, NextEnergy) for on-site deals; energy-supplier corporate-PPA desks (Statkraft, Centrica, EDF, Engie) for sleeved and multi-site supply; utility-scale developers and IPPs (Lightsource bp, Ørsted, RWE, Anesco, Voltalia) for corporate and virtual PPAs; and infrastructure funds (Greencoat, Octopus Energy Generation, Gresham House). We are an independent matching layer that introduces you to the right one.
Match the provider type to your structure and size: a 250 kWp rooftop deal suits a specialist rooftop fund, a multi-site retail estate suits a supplier-sleeved PPA, and a 10 MWp+ requirement suits a utility-scale developer. The fastest route is our 60-second form — we map your site to vetted providers active in your sector and return an indicative tariff shortlist within one working day.
Licensed electricity suppliers (the sleeving route) are regulated by Ofgem. Solar funds and developers that own on-site assets are not energy suppliers, so the contract — not a regulator — protects you; that is why the off-taker's legal review and provider due diligence matter. We are an editorial advisory and introducer, not an FCA-authorised broker; we disclose our referral fee before any introduction.
Going direct means approaching one provider and taking their offer. A provider-neutral introducer compares several providers' tariffs and terms for your specific site, so you see the market rather than a single quote. We are paid a disclosed referral fee on a completed deal and take no provider commission, so the shortlist is not skewed.
Typical 2026 UK terms are a 10–25 year contract at 9–18 p/kWh year-1 for on-site deals (lower for large behind-the-meter, higher for sleeved), with a fixed or RPI/CPI-linked escalator, full provider-funded O&M, and three end-of-contract options (extend, buy at fair market value, or free removal). Larger and investment-grade off-takers achieve the lower tariffs.
Tell us your site and we return an indicative p/kWh tariff and a 3–5 provider shortlist within one working day. Provider-neutral. No commission.
