Speed awareness course likely offered

At 37 mph in a 30 limit you are typically eligible for a National Speed Awareness Course — no points and no fine, but a course fee (around £80–£100) and the offer is at the force's discretion.

Speeding fines by speed limit

The recorded speed (mph) at which each outcome typically applies in England & Wales, for a first offence. Based on NPCC enforcement guidance and the Sentencing Council speeding guideline.

Figures are typical guidance, not a guarantee — the “10% + 2 mph” tolerance is advisory and any speed over the limit can be enforced. A speed awareness course is only offered once every 3 years. Court bands can mean a short driving ban instead of points, and fines there are set as a percentage of weekly income (capped at £1,000, or £2,500 on a motorway).

The 10% + 2 rule

Most forces won't prosecute until you exceed the limit by 10% plus 2 mph. It's NPCC guidance, not law — any speed over the limit can be enforced.

Course, fine, or court

Low-end speeds may get a speed awareness course (once every 3 years). Otherwise it's a £100 fixed penalty and 3 points, or a court summons for higher speeds.

Bands A, B & C

Courts sort speeding into three bands by how far over you were. The band sets the fine (50–150% of weekly income) and whether a ban is on the table.

Speeding penalties — your questions

The things people ask most about UK speeding fines, points and bans.

What is the 10% + 2 mph rule?
Most UK police forces follow National Police Chiefs' Council guidance and won't normally prosecute until your speed exceeds the limit by 10% plus 2 mph — so about 35 mph in a 30, or 79 mph in a 70. It is guidance, not law: a force can legally act on any speed above the limit, and cameras can be set to tighter margins.
Will I be offered a speed awareness course?
A course is usually offered for lower-end speeding — roughly between the limit + 10% + 2 and the limit + 10% + 9 — provided you haven't attended one in the last 3 years and the police consider it appropriate. It means no penalty points and no fine, but you pay a course fee (usually around £80–£100).
How much is a speeding fine?
A fixed penalty is £100. If the case goes to court, the fine is based on your weekly income: Band A is 50%, Band B is 100% and Band C is 150% of relevant weekly income, within ranges set by the Sentencing Council. Fines are capped at £1,000, or £2,500 if you were caught on a motorway.
How many penalty points will I get?
A fixed penalty adds 3 points. At court, Band A is 3 points, Band B is 4–6 points (or a 7–28 day disqualification) and Band C is 6 points (or a 7–56 day disqualification). Points stay on your licence record for 4 years from the offence.
Can I be banned from driving for speeding?
Yes. The court can impose a short discretionary ban for higher speeds (Bands B and C). Separately, reaching 12 or more penalty points within 3 years triggers a 'totting-up' disqualification of at least 6 months.
What is the New Driver Act?
If you passed your test less than 2 years ago and reach 6 or more penalty points, the DVLA revokes your licence. You then have to reapply for a provisional licence and pass both the theory and practical tests again. Just two speeding fixed penalties (3 points each) can trigger this.
How long does a speeding fine take to arrive?
If you weren't stopped at the roadside, police must post a Notice of Intended Prosecution (NIP) to the registered keeper within 14 days of the offence. The NIP and the Section 172 form asking who was driving usually arrive together; a Fixed Penalty or court date follows after you return the driver details.
Will speeding points increase my car insurance?
Usually yes. Three points for a minor speeding offence (code SP30) typically raise premiums by a modest amount, while higher bands, a court conviction or a ban cost more. You must declare points to your insurer, and they normally affect quotes for the time the conviction is 'spent' (often 5 years), even though points sit on your licence for 4.
What is the minimum speed for a speeding ticket?
Legally, any speed above the posted limit can be enforced. In practice most forces follow the NPCC '10% + 2 mph' guideline before acting — for example 35 mph in a 30, 46 mph in a 40, or 79 mph in a 70 — but this is discretionary and some cameras are set tighter.
Is this speeding fine calculator free and accurate?
Yes, it's completely free with no sign-up. It estimates outcomes for England & Wales from the published Sentencing Council speeding guideline and NPCC enforcement guidance, and the logic is unit-tested. It's a guide, not a guarantee — the final outcome depends on the police force and the court's discretion.
Is this calculator legal advice?
No. It gives an estimate for England & Wales based on published Sentencing Council guidelines and NPCC guidance. The actual outcome depends on the police force, the court's discretion and your individual circumstances. If you've received a notice, consider speaking to a motoring solicitor.
Do you store the details I enter?
No. Every calculation happens entirely in your browser. Your speed, income and points are never sent to a server or stored anywhere. A shared link only contains the values you choose to share.
