REGO sales 2026 — how UK commercial solar generators sell Renewable Energy Guarantees of Origin certificates above 1MW. Prices, brokers, contracts.
Renewable Energy Guarantees of Origin (REGOs) are certificates issued by Ofgem to UK renewable generators. One REGO corresponds to one megawatt-hour (MWh) of certified renewable electricity. They are the UK's equivalent of the EU's Guarantees of Origin and serve a single market function: they allow energy suppliers to claim a 'renewable' fuel mix for their domestic tariffs without buying the underlying electricity directly. This separation — sometimes called certificate ‘de-coupling’ — means the electricity you generate can be sold to one buyer (via PPA or SEG) while the renewable claim is sold separately to another buyer through the REGO market.
For most commercial solar systems under 1MWp, REGO sales add a modest 0.5p-1p per kWh on top of the SEG export tariff — useful but not transformative. For larger systems (above 1MWp, where SEG no longer applies and you operate in the wholesale market), REGOs become an important revenue stream alongside the wholesale electricity price. Solar farms above 5MWp typically derive 10-20% of total revenue from REGO sales.
| REGO scheme regulator | Ofgem |
| Issuance basis | 1 REGO per MWh of renewable generation |
| Current REGO market price (2026) | Approximately £8 – £20 per certificate (i.e. 0.8p – 2p per kWh) |
| Cost to register | £375 per accreditation + £30 per year (fees subject to change) |
| Common brokers | ENGIE, Bryt Energy, ECOHZ, Renewables Trading |
| Best fit | Solar systems above 1MWp; particularly solar farms and large industrial rooftops |
Submit an REGO accreditation application through Ofgem's online portal. Documents required: MCS certificate (where applicable), metering description, DNO connection agreement, system specification.
Half-hourly metering data feed to Ofgem. Most renewable generators use an accredited third-party data agent.
Issued quarterly by Ofgem to your REGO Register account.
Most generators use a broker (ENGIE, Bryt Energy, ECOHZ, Renewables Trading) to find buyers among energy suppliers. Contracts can be spot or 1-3 year forward.
Ofgem's REGO Register handles the transfer at the point of sale.
Typically 30-60 days from REGO transfer.
Most successful 2026 commercial solar projects use a combination of schemes — this is where independent advice earns its keep. REGO sales — selling renewable origin certificates from your solar typically combines well with:

As of May 2026, the scheme's funding status is: Ongoing — REGO scheme runs continuously. We re-check application windows monthly — if this is critical to your planning, request an eligibility check for the current programme status.
Typical award range: 0.5p – 2p per kWh of renewable generation (REGO market price). The size of any individual award depends on project capex, sector eligibility, match funding available and the scheme's per-applicant cap.
Ofgem (issuance); broker market (sales). Applications are submitted through the administrator's process — we link the relevant gov.uk and scheme pages at the bottom of this guide.
REGO accreditation has a cost. Fees of £375 + £30 annual are small for large systems but uneconomic for systems below 50kWp. REGO market prices are volatile. They moved from £0.50 per certificate in 2017 to over £30 per certificate in 2022 (driven by oversupply concerns and EU GO market pressure). Current 2026 pricing is around £8-£20. Brokers take 5-15% margin. Direct sales to energy suppliers are possible but harder for smaller generators.
