One desk for the two carbon instruments most UK businesses now need: ETS allowances (UKAs and EUAs) for regulated Scope 1 emissions, and REGO/GOO certificates for matching electricity and biomethane supply.

UKAs (UK Emissions Trading Scheme allowances) and EUAs (EU ETS allowances) are the settlement instruments that ETS-regulated installations must surrender to cover their reported emissions every year. We broker both into your operator account: spot purchases against compliance deadlines, forward tranches across the curve, and calendar-driven execution where you want price certainty against a budget. UKA and EUA pricing on this page tracks the same wholesale feed as /tools/carbon/uk-ets and /tools/carbon/eu-ets, so you see the level we're trading against in real time.

A REGO is a per-MWh certificate that Ofgem issues to a UK renewable generator each time they export to the grid. The certificate is uniquely numbered, ties back to the named generation site, and is retired against your meter when matched to your consumption. Eligible sources include onshore and offshore wind, solar PV, hydro, and qualifying biomass. We can supply REGOs from a specific technology mix on request, including 100 percent wind or fully traceable single-generator supply where suppliers offer it.

A GOO is the gas equivalent. Biomethane is produced from anaerobic digestion of agricultural feedstock, food waste, landfill gas, or sewage gas, then injected into the national network. The GOO certifies that the volume of gas you consumed was matched by an equivalent volume of biomethane injected upstream. Like a REGO, each GOO is uniquely numbered and independently auditable.

Bringing allowances and certificates onto one desk keeps the audit trail clean. UKAs and EUAs cover the regulated Scope 1 emissions you cannot reduce away; REGO-backed electricity lets you report zero market-based Scope 2 under the GHG Protocol; GOO-backed biomethane closes the loop on the Scope 1 fuel emissions that ETS does not cover. SECR, ESOS Phase 4, and CDP all sit on top of the same evidence pack. Pair with Purely Insights to track tonnes of CO2e covered and avoided per site per month.

What’s included

Every feature listed ships in the standard product. Nothing here is a paid upgrade.

Allowances and certificates

  • UKA execution for UK ETS-regulated installations, registry transfer handled
  • EUA execution for EU ETS-regulated and CBAM-exposed installations
  • Ofgem-issued REGOs for every MWh of electricity consumed
  • Ofgem-issued GOOs for every MWh of biomethane gas
  • Certificates and allowances uniquely numbered, fully traceable
  • Independent audit trail for each retirement and allowance transfer
  • Technology-specific REGOs available (100% wind, 100% solar, etc.)
  • Optional single-site PPA matching for I&C portfolios

Reporting and disclosure

  • UK ETS and EU ETS surrender packs ready for compliance deadlines
  • GHG Protocol market-based Scope 2 reporting (zero electricity emissions)
  • SECR-ready emissions data, by site and by fuel
  • ESOS Phase 4 evidence pack with consumption and certificate trail
  • B-Corp supply-chain documentation on request
  • Carbon Disclosure Project (CDP) input data formatted to spec
  • Custom investor and stakeholder reports via Insights

Allowance trading and supply pricing

  • UKA and EUA pricing tracked live against the same feed as /tools/carbon/uk-ets and /tools/carbon/eu-ets
  • Single-trade, tranched, or calendar-driven execution on allowances
  • Available on Fixed contracts, Flex strategies, or pass-through
  • Single-fuel (electricity-only) or dual-fuel (electricity + gas) supply
  • REGO premium typically £1 to £4/MWh on electricity
  • Biomethane GOO premium typically 2 to 6 p/kWh on gas, technology dependent
  • Volume tranching on biomethane and allowances to manage premium when the curve dips

Frequently asked questions

  • Is REGO-backed electricity actually renewable?

    It is supply matched by certificate. The electrons in your wires are the same grid mix as everyone else's, but for every MWh you consume there is a REGO retired that proves an equivalent MWh was generated from a UK renewable source and exported to the grid. Under the GHG Protocol market-based method, that allows you to report zero Scope 2 emissions on the matched volume.

  • Why not just buy carbon offsets instead?

    Offsets are a different instrument and they sit higher in the avoidance hierarchy: avoid first, reduce next, substitute renewable supply where possible, then offset what is left. REGO-backed supply is a substitution, not an offset. It also tends to score better with stakeholders, lenders, and rating agencies because it is independently audited by Ofgem.

  • Can I pick the technology mix?

    Yes, where suppliers can source it. Common requests are 100 percent wind, 100 percent solar, or hydro-only. Some I&C portfolios also negotiate single-generator matching via a PPA-style arrangement. Single-technology premiums vary so we model it before you commit.

  • What about REGOs sourced from the EU?

    We arrange Ofgem-issued UK REGOs only. EU GoOs (Guarantees of Origin) are sometimes used in the UK market but they are weaker evidence and increasingly rejected by sustainability standards. If you want UK provenance, we have it.

  • Is biomethane the same as natural gas?

    Chemically it is identical, methane is methane. The difference is the source. Biomethane comes from anaerobic digestion of organic matter, captured and upgraded to grid-injection quality. The carbon released when you burn it is biogenic, not fossil, so it is treated as net-zero under most accounting standards.

  • How is the price quoted?

    Every Purely Energy quote breaks the unit price into its four components: wholesale energy, non-commodity costs, the supplier margin, and the Purely margin. You see all four before you sign. There is no all-in price hiding a broker uplift, and no commission paid by the supplier you do not know about.

  • Can I get green supply on a Flex contract?

    Yes. REGO-backing layers cleanly onto Fixed, Flex, and pass-through contracts. The certificate retirement happens at consumption time so it does not change the trading mechanics of Flex.

  • Do you stay involved after the contract is signed?

    Yes. Full contract support is included for every customer for the life of the agreement. That covers bill validation, query handling, supplier escalations, change-of-tenancy events, and renewal-timing recommendations. We are not a one-and-done broker.
