Cardiff Energy Franchises and Rate Approval

Utilities and Infrastructure Wales 3 Minutes Read ยท published February 12, 2026 Flag of Wales

In Cardiff, Wales, energy distribution infrastructure and the approval of works intersect between national regulators and local highways and planning controls. Local authorities do not set electricity distribution tariffs but they control street works, wayleaves and highway licences required to install or alter cables and equipment within the city. This guide explains which Cardiff departments and national regulators are involved, the permit and notification steps, enforcement and common breaches to watch for.

Who regulates distribution and local permits

Electricity distribution companies and tariffs are regulated at UK level by Ofgem; local delivery of works in Cardiff requires permits, licences and close coordination with the council as highways authority. Ofgem: Electricity distribution[2]

Permits, wayleaves and approvals

Any party proposing to install, divert or maintain energy distribution apparatus in the highway must follow Cardiff Council application and street-works procedures and obtain necessary licences or permits before starting work. Cardiff Council Highways Licences[1]

Contact the council early to confirm whether a licence, wayleave or street-works permit is required.

Penalties & Enforcement

Enforcement responsibilities are split: Cardiff Council enforces highway licences, reinstatement and street-works conditions; Ofgem enforces price controls and wider network obligations for distribution companies. Specific sanction amounts and procedural fines are not always set out on single municipal pages and may be controlled by statute or regulator rules.

  • Fines: amounts for local highway or street-works breaches are not specified on the cited Cardiff page; where national legislation applies, specific penalties may appear in the controlling statute or national regulator notices.[1]
  • Escalation: first, repeat and continuing offence ranges are not specified on the cited council page; enforcement typically moves from notices to fixed penalties or prosecution depending on severity and persistence.[1]
  • Non-monetary sanctions: council orders to reinstate, stop-work notices, seizure of apparatus, and court action where required are available to the highways authority and are applied through statutory enforcement routes.[1]
  • Enforcer and complaints: Cardiff Council Highways & Transportation and the street-works team handle inspections and complaints; use the council highways contact and reporting pages for enforcement requests.[1]
  • Appeals and review: appeal routes depend on the specific notice or penalty; time limits for appeals are not specified on the cited council page and may be set out in the notice or in statutory appeal provisions.
If you receive a stop-work or reinstatement notice act quickly to avoid escalation.

Applications & Forms

Cardiff Council publishes guidance on highway licences and the street-works regime; applicants should consult the council Highways Licences page for submission instructions and contact details.[1] Specific form numbers, fee schedules and fixed deadlines are not specified on that cited page and must be confirmed by the council during pre-application checks.

Common violations and typical outcomes

  • Undertaking works without a highway licence or permit โ€” may trigger stop-work notices and orders to reinstate or penalty proceedings.[1]
  • Poor reinstatement after excavation โ€” leads to remedial orders and possible cost recovery by the council.
  • Failure to notify statutory undertakers or the Distribution Network Operator (DNO) โ€” risks coordination failures and enforcement action by the highway authority.
Document communications with the council and the DNO to support compliance and appeals.

FAQ

Who approves energy distribution tariffs in Cardiff?
Tariffs and distribution company price controls are set and enforced by Ofgem, not by Cardiff Council; the council controls local permits for physical works.
Do I need a council licence to lay cables in a Cardiff street?
Yes. Works in the highway typically require a highway licence or street-works permit from Cardiff Council and coordination with the DNO; consult the council Highways Licences page for details.[1]
How do I report unauthorised works or a defective reinstatement?
Report the issue to Cardiff Council Highways & Transportation using the council reporting pages; provide photos, location and dates to help enforcement.

How-To

  1. Confirm responsibility: identify the DNO and contact them to agree network connections and safety requirements.
  2. Pre-application: contact Cardiff Council Highways to check if a highway licence or permit is required and request application guidance.
  3. Submit applications: complete any council highway licence or street-works permit forms and provide plans, traffic management and restoration proposals.
  4. Carry out works: follow approved methods, notify the council for inspections and the DNO for safety checks; keep records of notices and communications.
  5. Reinstate and close: complete reinstatement to council standards, arrange final inspections and obtain written confirmation that works are closed.
