Business and Consumer Protection England 4 Minutes Read · published February 02, 2026 Flag of England

In London, England, consumers and businesses must be able to rely on accurate measurements at petrol stations. This guide explains who enforces accuracy, how to report a suspect pump, and what to expect from Trading Standards and national regulators. It covers evidence to collect, likely enforcement paths, and practical steps to lodge a complaint in London.

Keep the pump display photo, receipt and time of transaction when you report a suspected inaccuracy.

Who enforces fuel pump accuracy

Local Trading Standards services enforce weights and measures rules for fuel dispensers in London boroughs; the City of London Corporation provides a Trading Standards service for its area which explains reporting and inspection responsibilities [1]. The legal basis for offences is set out in the Weights and Measures Act 1985 and related statutory instruments [2]. The Office for Product Safety and Standards provides national guidance and oversight on legal metrology policy [3].

How to identify a likely inaccuracy

  • Take a clear photo of the pump display showing price and litres.
  • Keep the paper receipt showing volume and total paid.
  • Note the date, exact time and pump number on site.
  • Note the station name, address and attendant details if available.

Penalties & Enforcement

Enforcement action for inaccurate fuel pumps is taken by the local Trading Standards service acting under the Weights and Measures Act 1985 and associated regulations [2]. Specific fine amounts and detailed escalations are not consistently published on local Trading Standards summary pages and therefore are not specified on the cited page; consult the statutory text or the enforcing local authority for current penalty figures [2].

  • Monetary fines: not specified on the cited page; see statutory instrument references for exact figures [2].
  • Escalation: first, repeat and continuing offences procedures are set by prosecution policy but specific ranges are not specified on the cited page [1].
  • Non-monetary sanctions: sealing or withdrawal of equipment, prohibition notices, seizure of goods and court action are enforcement options; local pages describe inspection and intervention but specific orders are not specified on the cited page [1].
  • Enforcer: local Trading Standards (contact the Trading Standards office for the borough where the station is located) [1].
  • Inspection and complaints: submit photos, receipt and details via your local Trading Standards complaint channel; City of London provides contact guidance for its area [1].
  • Appeal and review routes: prosecutions and statutory notices may be appealed in the relevant court or administrative review; time limits are determined by the specific notice or prosecution schedule and are not specified on the cited page [2].
  • Defences/discretion: defences such as reasonable excuse or evidence of recent calibration may be relevant; consult the enforcing authority and statutory text for detail [2].
If you believe a pump is under-delivering, act quickly to preserve receipt evidence and timestamps.

Applications & Forms

No universal national complaint form for inaccurate fuel pumps is published on the cited local pages; complaints are submitted to the relevant local Trading Standards office, which may provide an online form or email contact for the borough in which the station sits [1]. For national guidance on legal metrology and approved procedures consult the Office for Product Safety and Standards [3].

Action steps to report a suspect fuel pump

  • Collect evidence: photos of the pump display, the receipt, pump number and time of fill.
  • Find the correct local Trading Standards contact for the station location and submit your complaint with evidence [1].
  • Record follow-up: note any reference number or case ID and expected timelines provided by the authority.
  • If unsatisfied, ask the enforcing authority about appeal routes or escalation to the national regulator for policy issues [3].
