Sustainability isn't a product. It's how we operate.
B-Corp score 87.6 / 200 certified. Real Living Wage Employer. Science-based targets validated by SBTi. Walking the walk, not just brokering green tariffs.
Our net zero roadmap
Concrete milestones, not vague promises. Here is where we are and where we are going.
B-Corp journey begun
Started the B Impact Assessment process with B Lab, the non-profit that audits companies against the certified-B-Corp standard.
100% renewable electricity for operations
All electricity consumed at our Warrington office is now matched by REGO-backed renewable generation.
B-Corp certified, verified score 87.6
Awarded B-Corp certification by B Lab against a verified score of 87.6 out of 200, well above the 80-point pass bar. Recertification due on the standard three-yearly cycle.
Science-based targets validated (SBTi)
Our emissions reduction targets have been validated by the Science Based Targets initiative, aligned with a 1.5C pathway.
Real Living Wage Employer accredited
Accredited as a Real Living Wage Employer by the Living Wage Foundation on 10 May 2026, committing every member of the Purely Energy team in the UK to pay at or above the voluntary Real Living Wage, including third-party staff working regularly on our premises.

Understanding REGOs and GOOs
The certification systems behind genuine green energy, and how to spot greenwash.
What are REGOs?
Renewable Energy Guarantees of Origin
REGOs are certificates issued by Ofgem for every megawatt-hour (MWh) of electricity generated from a renewable source in the UK. Wind farms, solar installations, and hydroelectric plants each receive one REGO per MWh produced.
When a supplier purchases and retires a REGO on your behalf, they are matching your electricity consumption to a specific unit of renewable generation. This is how your supply is certified as “green.”
What are GOOs?
Guarantees of Origin for gas
GOOs serve the same purpose as REGOs but for gas. They certify that a unit of gas has been produced from a renewable source, typically biomethane injected into the national gas grid.
GOO-backed gas allows businesses to reduce their Scope 1 emissions from heating and industrial processes without switching away from gas infrastructure. We arrange GOO-backed supply through panel suppliers using verified UK biomethane producers, with full certificate traceability.
How it works
Step 1
Renewable generator produces energy
Step 2
Ofgem issues one REGO/GOO per MWh
Step 3
Supplier purchases & retires certificates
Step 4
Your supply is certified renewable
Not all “green” tariffs are equal
Some suppliers buy cheap, unbundled REGOs from the previous year and attach them to brown electricity. Technically legal, but it does nothing to increase renewable generation. When evaluating green tariffs, ask:
- Are the REGOs/GOOs from the same period as your consumption?
- Are they from UK generators, or imported from overseas markets?
- Does the supplier invest in new renewable capacity, or just buy surplus certificates?
- Can they provide you with a certificate showing exactly which generators your supply was matched to?
At Purely Energy, we only procure time-matched, UK-sourced certificates and provide full traceability for every unit supplied.
Which sustainability framework applies to you?
Frameworks are how the regulator, your customers, your investors and your own board check that you're actually doing something. Pick the wrong one and you waste a year of work; pick the right one and you stop the awkward questions before they start. Our roadmap builder picks for you.
UK ETS (UKAs)
UK Emissions Trading Scheme (UK Allowances)- Who needs it
- Energy-intensive industries, power generators (above 20 MW thermal input) and operators of UK domestic flights covered by the UK ETS.
- What it requires
- Hold one UK Allowance (UKA) for every tonne of CO2e emitted, surrender annually by 30 September. Free allocation reducing toward auction-only by 2030. Free allowances cut 12% by 2027.
- Deadline
- Annual surrender by 30 September; verified emissions reporting by 31 March.
EU ETS (EUAs)
EU Emissions Trading System (EU Allowances)- Who needs it
- UK operators with sites in the EU, importers covered by CBAM, or businesses bidding into European supply chains where EU ETS exposure matters.
- What it requires
- Hold one EU Allowance (EUA) per tonne of CO2e, surrender annually. CBAM phase-in 2026 onward extends carbon pricing to imported steel, aluminium, cement, fertiliser, electricity and hydrogen.
- Deadline
- Annual surrender by 30 September; CBAM declarations quarterly during the transition period.
SECR
Streamlined Energy and Carbon Reporting- Who needs it
- Large UK companies (250+ staff or £36m+ turnover and £18m+ balance sheet), and quoted companies of any size.
- What it requires
- Annual disclosure of UK energy use, Scope 1 and Scope 2 GHG emissions, energy efficiency actions, and an intensity ratio. Goes in the directors' report.
- Deadline
- Annually, alongside your statutory accounts.
ESOS Phase 4
Energy Savings Opportunity Scheme- Who needs it
- UK undertakings with 250+ staff, or turnover above £44m and balance sheet above £38m. About 10,000 organisations.
- What it requires
- An energy audit covering at least 95% of your total energy consumption, signed off by a Lead Assessor. Phase 4 compliance period started 2026.
- Deadline
- Compliance notification due by 5 December 2027 for Phase 4.
Carbon Reduction Plan
PPN 03/21- Who needs it
- Any business bidding for UK central government contracts above £5m a year.
- What it requires
- A signed Carbon Reduction Plan committing to net zero by 2050, with current Scope 1, 2, and selected Scope 3 emissions disclosed and a reduction trajectory.
- Deadline
- Required at the point of bid; refreshed annually thereafter.
B-Corp
Certified B Corporation- Who needs it
- Businesses that want a recognised stamp on their commitment to people, planet, and governance, not just shareholders.
- What it requires

- Deadline
- Voluntary. Plan a 6 to 12 month assessment cycle.
SBTi
Science Based Targets initiative- Who needs it
- Businesses serious about credible 1.5 degree-aligned reduction targets, often required by major customers and investors.
- What it requires
- Submit near-term and net zero targets aligned with the SBTi Corporate Net-Zero Standard. Targets are validated against climate science.
