A confirmation checklist for energy businesses. Work through the cross-cutting duties every energy business shares, then the section for what you operate — electricity generation, electricity networks, gas networks and gas manufacture, energy supply, or heat, steam and air conditioning.

Confirm the obligations that apply to your energy business are in place. Start with section 1, which applies to every energy business, then complete the section for what you operate — answer only the items for the activities you actually run. Where a duty differs by nation, the item says so. If you operate in Northern Ireland, your licences come from the Utility Regulator (UREGNI), not Ofgem — work through this checklist alongside the Northern Ireland licensing guide.
Protect employees and others under the Health and Safety at Work etc. Act 1974 — in this sector that means treating major-hazard risk as core compliance work (Great Britain; HSENI enforces in Northern Ireland).
At least £5 million employers' liability cover from an authorised insurer if you employ anyone — energy-sector insurers typically require £10 million or more (Great Britain; equivalent rules in Northern Ireland).
Permit any activity with emissions to air, water or land — Environment Agency in England, NRW in Wales, SEPA in Scotland, NIEA in Northern Ireland. Large combustion plant needs IED-specific permits.
If any installation exceeds the threshold (generally more than 20 MW thermal input), hold a greenhouse gas emissions permit, submit a verified annual report by 31 March and surrender allowances by 30 April.
If a site holds dangerous substances — LNG, hydrogen, flammable gases — at or above threshold quantities, notify the competent authority, maintain a major accident prevention policy, and for upper-tier sites a safety report and emergency plan (Great Britain; Northern Ireland has parallel regulations).
Generators above 50 MW need an Ofgem generation licence; most under 50 MW qualify for a class exemption. Confirm which side you fall on — operating unlicensed without an exemption is a criminal offence. Northern Ireland licences come from UREGNI. Confirm against the electricity generation licensing guide.
Every generator exporting to the grid needs a connection agreement — with your Distribution Network Operator for smaller connections or NESO for transmission-scale projects.
Onshore stations over 50 MW in England need a Development Consent Order; in Wales consenting up to 350 MW is devolved to Welsh authorities (onshore wind from 10 MW follows the Developments of National Significance route; above 350 MW, a DCO); in Scotland, section 36 consent from Scottish Ministers. Smaller projects need local planning permission.
Accredit for Contracts for Difference (the Renewables Obligation is closed to new accreditation — existing accredited stations keep receiving certificates), register for REGO certificates, and consider Capacity Market participation — administered by Ofgem (RO, REGO), the Low Carbon Contracts Company (CfD) and NESO under DESNZ oversight (Capacity Market).
Nuclear installations need an ONR site licence and third-party liability insurance. Confirm against the civil nuclear industry guide.
Transmission and distribution each need their own Ofgem licence; IDNOs need a distribution licence and ICPs need NERS accreditation (Great Britain — NIE Networks is regulated by UREGNI).
Transmission licence holders must comply with the Grid Code and CUSC, administered by NESO.
Submit annual regulatory accounts and performance data to Ofgem under RIIO-T (transmission) or RIIO-ED (distribution).
DNOs must pay automatic compensation for supply interruptions beyond set durations and report interruption statistics to Ofgem annually.
Conveying gas through pipes to premises needs an Ofgem gas transporter licence (the Gas Act 1986 does not extend to Northern Ireland).
Gas transporters — and gas manufacturing processes connected to a network — must have a safety case explicitly accepted by HSE before conveyance or operations begin. There is no tacit consent.
Notify HSE of major accident hazard pipelines (above 7 barg) and maintain a Major Accident Prevention Document.
Where more than one transporter shares a network, confirm the NEC arrangements and your duty to follow its directions in a supply emergency.
Licensed gas distribution businesses submit annual regulatory accounts and performance data to Ofgem.
Electricity supply and gas supply each need their own Ofgem licence; book gas transportation capacity under a shipper licence if you ship. Northern Ireland supply licences come from UREGNI.
Become a Balancing and Settlement Code party (electricity, with a Meter Operator and Data Aggregator appointed) and comply with the Uniform Network Code (gas).
Check every in-scope default and standard variable tariff against the quarterly Ofgem cap, for both fuels.
Meet guaranteed standards of service, handle complaints effectively, comply with Ofgem's Standards of Conduct, and report social obligations annually.
Settle the Renewables Obligation with certificates or buy-out, pay the CfD supplier obligation levy — and offer a Smart Export Guarantee tariff if you have 150,000 or more domestic customers.
Track the Energy Act 2023 implementation timetable, prepare for Ofgem authorisation, and comply with the Heat Network (Metering and Billing) Regulations now (Great Britain).
Hold a written scheme of examination for every steam boiler, pressure vessel and high-pressure main, with periodic competent-person examinations recorded (Great Britain).
Company certificate plus personal certificates for engineers handling fluorinated gases in cooling plant, with leak checks scaled to charge (GB regime).
Part L building-control compliance in England for notifiable heat and steam plant; Wales Part L, Scotland Section 6, Northern Ireland Part F.
Register Good Quality CHP under CHPQA for Climate Change Levy relief (UK-wide), and complete ESOS energy audits every four years if you meet the large-undertaking thresholds (Phase 4 deadline 5 December 2027).
