Cardiff Utility Connection Charges - City Bylaws

Utilities and Infrastructure Wales 4 Minutes Read · published February 12, 2026 Flag of Wales

Cardiff, Wales residents and contractors planning utility connections or works affecting the public highway should review city bylaws and permit requirements before starting work. Fees and charges vary by activity: highway openings, streetwork permits, and sewer or drainage connections each follow separate application routes. This guide summarises where to find official charges and which Cardiff department enforces rules, explains common violations and remedies, and gives clear action steps to apply, pay, report or appeal. For permit details contact the Council highways team and consult the official permit pages before scheduling any works.[1]

Charges & Fees for Utility Connections

Cardiff Council charges for activities in the highway and related permits are published on the Council pages for highway licences and streetworks; specific fee tables and payment methods appear on those official pages. Charges for sewer connections and discharges are administered by the statutory water company and its developer services; Cardiff Council does not publish water-company connection tariffs on its highway pages. If a stated fee or tariff is required for an application, the responsible authority will list it on its form or guidance page.

Check the Council permit page for the exact fee schedule before you apply.

Penalties & Enforcement

Enforcement for unlicensed highway works, unsafe reinstatements or breaches of permit conditions is carried out by Cardiff Council Highways and Streetworks teams. Where offences are set out on the Council permit pages the page will indicate enforcement routes; specific fine amounts are not always published on that page.

  • Fine amounts: not specified on the cited page; consult the permit or enforcement notice for figures.
  • Escalation: first, repeat or continuing offences may attract increased penalties or further action; ranges are not specified on the cited page.
  • Non-monetary sanctions: removal orders, stop notices, requirements to reinstate, and prosecution in the magistrates' court are used where compliance is not achieved.
  • Enforcer and complaints: Cardiff Council Highways/Streetworks department handles inspections and complaints; use the Council contact or report-a-problem routes to notify the authority.
  • Appeals and review: appeal routes depend on the statutory notice or permit condition; time limits for appeal are case-specific and are not specified on the cited page.
If you receive a notice act quickly to meet any compliance deadline or to lodge an appeal.

Applications & Forms

Applications for highway permits or licences are submitted through Cardiff Council pages for highway licences and streetworks; the Council publishes application forms, guidance and payment instructions on the permit pages. For sewer and drainage connection applications contact the statutory water company through its developer services. Where forms or schedule numbers apply they are named on the responsible authority's page; if no form is listed the Council will advise the correct route.

  • How to apply: complete the Council permit form or online application and pay any published fee as instructed on the permit page.
  • Fees listed: see the Council permit page for fee tables; if a fee is not shown on that page it is not specified on the cited page.
  • Supporting documents: traffic management plans, method statements and proof of competency are commonly required.

Common Violations and Typical Outcomes

  • Unauthorised road opening — likely enforcement notice, requirement to reinstate, possible prosecution.
  • Poor reinstatement or unsafe works — remedial order and rework at contractor expense.
  • Failure to obtain a permit — stop notices, fines or prosecution depending on circumstances.
Keep permits and records on-site until works are complete and accepted.
