What documents do you need for Ofgem authorisation?
Work through each requirement below. Check off the areas you have covered and see exactly where the gaps are.
Ofgem’s authorisation conditions cover nine operational areas. For each one, you need structured documentary evidence – not just policy statements. Most operators already do the right things operationally. The gap is formal documentation. This checklist helps you find where those gaps are.

What Ofgem requires
Every operator must register with Ofgem’s digital registration service and demonstrate they are a fit and proper organisation to hold an authorisation. This covers operator details, network information, governance arrangements, and the nominated individuals responsible for compliance.
What you need to evidence
A completed readiness assessment covering your organisation structure, the networks you operate, your governance framework, and the named individuals accountable for each compliance area.
What Ofgem requires
Consumers must receive the same standard of protection as gas and electricity customers. A formal welcome pack at first supply, transparent billing, a complaints procedure with Energy Ombudsman escalation, and a Priority Services Register for vulnerable consumers.
What you need to evidence
Four documents: a Consumer Welcome Pack, a Model Compliant Bill with correct layout and back-billing protections, a Complaint Log tracking receipt through to resolution, and a Priority Services Register.
What Ofgem requires
Operators must demonstrate they can sustain operations financially. Ofgem wants forward-looking assertions about working capital, insurance, emergency funding, and regulatory history – not just annual accounts.
What you need to evidence
A structured Financial Resilience Statement covering each area Ofgem specifies, presenting assertions about preparedness rather than backward-looking figures.
What Ofgem requires
Documented contingency arrangements for maintaining heat supply during disruption. Step-in procedures for when the operator can no longer supply heat. This is the section Ofgem reads most carefully.
What you need to evidence
A Supply Continuity and Step-In Plan covering each contingency scenario, with named contacts, notification timescales, and a credible step-in arrangement.
What Ofgem requires
Periodic data returns. Quarterly: consumer numbers, new connections, complaints. Annually: financial performance, interruptions, PSR usage, and consumer satisfaction.
What you need to evidence
A reporting tracker mapping every required metric, submission frequency, data source, and reference guidance.
What Ofgem requires
Staff involved in heat network operations must hold appropriate competencies and receive ongoing training across technical, customer-facing, and compliance roles.
What you need to evidence
A training register recording qualifications, training dates, renewal schedules, and competency assessments.

What Ofgem requires
The Heat Network Technical Assurance Scheme sets phased requirements for network condition, metering accuracy, water treatment, and supply reliability. The draft standard (TS1) was published November 2025. Existing networks get staged milestones.
What you need to evidence
Three registers: network condition and compliance status, water quality and chemical dosing records, and meter calibration and accuracy testing.
What Ofgem requires
Every consumer must have a formal heat supply agreement meeting Ofgem’s requirements for transparency, fairness, and consumer rights. Clear tariff schedules, termination rights, and accessible formats.
What you need to evidence
A consumer-facing heat supply agreement with tariff schedule and operator guidance, in standard and accessible formats.
What Ofgem requires
Scottish operators face dual compliance. The Heat Networks (Scotland) Act 2021 licensing regime runs alongside the Market Framework authorisation conditions. Scottish operators must satisfy both frameworks.
What you need to evidence
The Scotland-specific HNO Readiness Pack addresses both sets of requirements in a single document. Only required if you operate networks in Scotland.
