On 27 January 2026 — the day Ofgem began regulating heat networks — just 290 suppliers had registered with the Energy Ombudsman, against an estimated 14,000 operational sites. Domestic consumer complaints reach back to 1 April 2025. Decisions take about six weeks. The first regulator most operators meet will not be Ofgem.

"The working assumption in the sector is that Ofgem is the enforcer, that Ofgem will take a collaborative approach, and that operators will get a warning letter and time to prepare. Every part of that assumption is defensible. It is also the wrong model."
"The Energy Ombudsman has been the statutory redress body for heat network consumers since 1 April 2025. Its caseload is complaint-led, not selected by regulatory prioritisation. A 50-unit scheme is as exposed as a 5,000-unit scheme — one articulate resident is all it takes. Decisions are legally binding on the supplier once the complainant accepts them. There is no grace period and no transitional flexibility."
"An adverse Ombudsman finding does not stay contained. Paragraph 10.13 of the Ombudsman's Terms of Reference allows it to refer non-compliant suppliers to Ofgem. Ofgem's penalty powers are up to £1 million or 10% of annual turnover, whichever is higher. The £10,000 award cap on a single complaint is where the financial exposure begins, not where it ends."
Read the full white paper: The Energy Ombudsman Will Be Your First Regulator →Heat Network Compliance generates the documentation that decides whether a complaint is contained or escalates. All 29 final-determined Ofgem Authorisation Conditions across Sections A, B and C — in the operator's or supplier's own name. Wizard-driven, not template-based. Each document reflects the regulated party's specific network type, organisational structure, and regulated role, and is produced as a board-ready DOCX. Built by a serving heat network compliance consultant against the 13 January 2026 Ofgem decision.

See Tariff Calculator →BESA v3.1-aligned commissioning reports. Free tier available, paid tiers from £50.
See HIU Tool →You are likely both operator and supplier under the Regulations. Tenant complaint procedures, vulnerability protections, and Priority Services Register obligations apply directly to you under Section B. The Policy Document Generator handles Section B obligations as a regulated bundle, with HRA-specific framing in the wizard.
See vulnerability and PSR guidance →Procurement-friendly tier pricing — well within UK public sector thresholds, no committee approval required. The Consultancy Subscriber model lets your supporting consultancy take on documentation across multiple LA-owned schemes without re-procuring per network.
See local authority registration pathway →Commercial, build-to-rent, and district networks — including ESCOs and SPVs operating networks owned by others — may be operator-only, supplier-only, or both. The wizard determines which AC sections apply to your regulated role and skips the rest — no document generated against an obligation that doesn't apply to you. Bulk supply and multi-party arrangements supported.
See operator and supplier guidance →A single account covering unlimited Named Clients. Each Named Client holds its own Company Information Schedule. All documents generated in the client's name — never yours, never a shared template.
See the Consultancy Subscriber model →Operators who engage with Ofgem early, self-report, and reach settlement before a final order can benefit from a penalty discount of up to 30% under the February 2026 Heat Networks Enforcement Guidelines. Compliance-ready operators are also better positioned to settle quickly when a problem surfaces — which is when the discount applies. Readiness is the only path that lets you defend the complaint and qualify for the discount.
Begin compliance documentation →Heat Network Compliance is built and maintained by Hamish McDonald — a serving heat network compliance consultant working with UK heat network operators, contributor to the Ofgem cost-recovery seminar series, and author of a four-paper white paper series on the Ofgem regime. The platform exists because no existing tool covered the specific documents Ofgem actually requires under the final-determined Authorisation Conditions.
