In London, England, drivers must follow national and local speed limits set and enforced by a mix of authorities including Transport for London and local boroughs.

It uses current official sources and shows where to find forms, complaint routes and contact points for enforcement and appeals. Read on for enforcement pathways, common violations, and clear action steps to pay, appeal or report speed-related issues in London.

How speed limits are set in London

Speed limits in London are implemented under national legislation and by local traffic authorities. Major routes and red routes are managed by Transport for London; local boroughs set limits on local streets via Traffic Regulation Orders. Road markings and signs indicate the enforceable limit; drivers should consult local signs and official maps for temporary or experimental limits.

Enforcers, inspections and complaint pathways

Speed enforcement in London is carried out by the Metropolitan Police and by authorised civil enforcement bodies for certain road regimes; Transport for London manages and coordinates enforcement on red routes and major arterial roads, and borough councils manage local streets and Traffic Regulation Orders.

  • To report dangerous or persistent speeding, contact local police or use the Met Police online advice pages. Met Police: Speeding advice and enforcement[2]
  • Borough-level Traffic Regulation Orders (TROs) and consultations are published by individual London borough councils; applications or complaints go to the relevant borough traffic team.

Appeals and review

Options to contest a notice are set out on the notice itself and in the issuing authoritys guidance. Where an FPN is issued you can generally elect for a court hearing rather than accept the fixed penalty; exact time limits for election or appeal vary by notice type and issuer and are not specified in full on the cited pages. GOV.UK: Penalty points and endorsements[1]

Keep a copy of all correspondence and the offence notice when preparing an appeal.

Defences and discretionary considerations

Common defences include mistaken identity, factual dispute about speed measurement, emergency circumstances or lawful defence under road rules; availability and success of defences depend on evidence and court discretion. Official pages list procedures for responding to notices but specific allowable defences are assessed case by case on court or prosecutor guidance.

Common violations and typical outcomes

  • Exceeding posted limit on a local street — likely fixed penalty or prosecution depending on excess and context.
  • Speeding on red routes or major roads — enforced by TfL/authorised partners; may carry same statutory penalties as other roads. Transport for London: Speed limits[3]
  • Excessive speed on motorways — higher maximum fines may apply (see GOV.UK). GOV.UK: Penalty points and endorsements[1]

Applications & Forms

Applications to change local speed limits or to request a Traffic Regulation Order are made to the relevant London borough or to Transport for London for red-route changes. There is no single national application form for all local speed limit changes; boroughs publish TRO consultation and application procedures on their council websites. For enforcement appeal forms or payment options, follow the instructions on the notice issued to you — specific form names and fees are published by the issuing authority and may vary by borough or enforcement body.

Contact your boroughs traffic team for the TRO application process and any local fees.
