Getting caught speeding in the UK can result in significant financial penalties that vary dramatically based on your speed and income. The current system calculates fines using a three-band structure that considers both the severity of the offence and your weekly earnings. Understanding how these calculations work can help you prepare for potential penalties and make informed decisions about your driving behaviour.
Understanding UK Speeding Fine Bands
The UK operates a sophisticated three-tier penalty system for speeding offences, implemented in 2017 to ensure proportionate punishment. This system replaces the previous flat-rate fines with income-based calculations that reflect both the severity of the speeding and the offender’s financial circumstances.
Band A Speeding Penalties
Band A represents the lowest level of speeding offences, typically involving speeds that exceed the limit by a relatively small margin. These cases usually result in fixed penalty notices rather than court appearances.
Speed Thresholds for Band A:
- 20mph zones: 21-30mph
- 30mph zones: 31-40mph
- 40mph zones: 41-55mph
- 50mph zones: 51-65mph
- 60mph zones: 61-80mph
- 70mph zones: 71-90mph
Band A Penalties:
- Fine: 50% of weekly income
- Penalty points: 3 points
- Disqualification: 7-28 days (in exceptional cases)
Most Band A offences receive fixed penalty notices of £100 with 3 penalty points, avoiding the need for court proceedings. However, if your case reaches court, the fine calculation becomes income-dependent.
Band B Speeding Penalties
Band B covers moderate speeding offences that represent a more serious breach of speed limits. These cases typically require court appearances and result in higher penalties.
Speed Thresholds for Band B:
- 20mph zones: 31-40mph
- 30mph zones: 41-50mph
- 40mph zones: 56-65mph
- 50mph zones: 66-75mph
- 60mph zones: 81-90mph
- 70mph zones: 91-100mph
Band B Penalties:
- Fine: 100% of weekly income
- Penalty points: 4-6 points
- Disqualification: 7-28 days or penalty points
The doubling of the income-based fine reflects the increased seriousness of these offences. Courts have discretion to impose either penalty points or short-term disqualification periods.
Band C Speeding Penalties
Band C represents the most serious speeding offences, involving extremely high speeds that pose significant danger to public safety. These cases always proceed to court.
Speed Thresholds for Band C:
- 20mph zones: 41mph and above
- 30mph zones: 51mph and above
- 40mph zones: 66mph and above
- 50mph zones: 76mph and above
- 60mph zones: 91mph and above
- 70mph zones: 101mph and above
Band C Penalties:
- Fine: 150% of weekly income
- Penalty points: 6 points
- Disqualification: 7-56 days or penalty points
The maximum 150% income penalty reflects the serious nature of these offences, which often involve driving at speeds significantly above legal limits.
Income Based Fine Calculation System
The UK’s income-based fine system ensures penalties are proportionate to offenders’ financial circumstances. This approach aims to create equal impact across different income levels whilst maintaining deterrent effects.
Weekly Income Assessment
Courts calculate fines based on your gross weekly income before tax and national insurance deductions. This figure includes:
- Employment wages and salaries
- Self-employment earnings
- Benefits and pensions
- Investment income
- Rental income
- Any other regular income sources
For unemployed individuals or those on benefits, courts use a standard weekly income figure of £120 for calculation purposes. Students and those with irregular income patterns receive similar treatment.
Income Verification Requirements:
- Recent payslips (usually last 3 months)
- P60 or tax return documents
- Benefits statements
- Bank statements showing regular income
- Employer confirmation letters
Minimum and Maximum Fine Limits
The income-based system operates within strict parameters to ensure fairness and prevent excessive penalties.
| Band | Minimum Fine | Maximum Fine | Income Percentage |
|---|---|---|---|
| A | £120 | £1,000 | 50% |
| B | £120 | £1,000 | 100% |
| C | £120 | £1,000 | 150% |
These limits prevent disproportionate penalties whilst ensuring meaningful deterrence across all income levels. The £120 minimum ensures even unemployed offenders face significant consequences.
Speed Thresholds and Detection Methods
Understanding when different penalty bands apply helps drivers assess potential consequences of speeding behaviour. The system uses specific speed thresholds that trigger different penalty levels.
Fixed Penalty Notices vs Court Summons
Police forces can issue fixed penalty notices for less serious speeding offences, typically those falling within Band A parameters. More serious cases proceed directly to court.
Fixed Penalty Notice Criteria:
- Speed not exceeding Band A thresholds
- No aggravating circumstances present
- Driver has valid licence and insurance
- No previous serious driving convictions
Court Summons Situations:
- Speeds exceeding Band A limits
- Repeat offenders within short periods
- Aggravating factors present
- Driver disputes the allegation
- Complex circumstances requiring judicial consideration
Speed Camera Tolerance Levels
Most UK police forces operate informal tolerance policies, typically allowing small margins above speed limits before issuing penalties. However, these policies are not legally binding and can change without notice.
Common Tolerance Approaches:
- 10% plus 2mph (e.g., 35mph in 30mph zone)
- Fixed margins (e.g., 3-5mph above limit)
- Variable tolerances based on road conditions
- Zero tolerance in specific areas (schools, roadworks)
These tolerances exist to account for speedometer inaccuracies and minor measurement variations. However, drivers should not rely on tolerances as they are discretionary and can be withdrawn.
Additional Penalties Beyond Fines
Speeding convictions carry consequences extending beyond financial penalties, affecting your ability to drive legally and your insurance costs.
Penalty Points System
The UK uses a penalty points system to track driving offences and identify repeat offenders. Points remain on your licence for specific periods depending on the offence severity.
Point Allocation by Band:
- Band A: 3 points
- Band B: 4-6 points
- Band C: 6 points
Point Duration:
- Most speeding offences: 4 years from conviction date
- More serious offences: 11 years from conviction date
- Points affect insurance for 5 years typically
Accumulating 12 or more points within three years triggers automatic disqualification under the “totting up” procedure, resulting in minimum six-month driving bans.
Driving Licence Disqualification
Courts can impose immediate disqualification instead of penalty points, particularly for serious offences or repeat offenders.
Disqualification Periods:
- Band A: 7-28 days (exceptional cases)
- Band B: 7-28 days or points
- Band C: 7-56 days or points
Factors Influencing Disqualification:
- Speed significantly above limit
- Previous convictions within two years
- Dangerous driving circumstances
- Professional drivers whose livelihood depends on driving
- Aggravating factors present
Factors Affecting Fine Calculations
Courts consider various factors when determining final penalties, potentially increasing or decreasing standard band penalties based on specific circumstances.
Aggravating Circumstances
Certain factors can increase penalties beyond standard band calculations, reflecting the increased danger or irresponsibility of the offending behaviour.
Common Aggravating Factors:
- Speeding in poor weather conditions
- Heavy traffic or pedestrian areas
- School zones during active hours
- Roadworks or temporary speed limits
- Towing trailers or carrying passengers
- Previous convictions for similar offences
- Attempting to avoid detection
- Racing or competitive driving behaviour
These factors can result in higher fines within the permitted ranges and influence decisions about disqualification versus penalty points.
Mitigating Factors
Courts also consider circumstances that might justify reduced penalties, though these rarely eliminate consequences entirely.
Recognised Mitigating Factors:
- Emergency situations requiring urgent travel
- Medical emergencies (passenger or family)
- Clear driving record over extended periods
- Genuine speedometer defects (with evidence)
- Temporary signage confusion in roadworks
- Early guilty pleas and cooperation
- Demonstrated remorse and attitude change
- Employment consequences of disqualification
Successful mitigation typically reduces fines within band limits rather than changing penalty bands entirely.
Payment Options and Deadlines
Understanding payment procedures and deadlines helps avoid additional penalties and complications following speeding convictions.
Fixed Penalty Notice Payment:
- Payment deadline: 28 days from issue
- Online payment available through government portals
- Postal payments accepted with cheque or postal order
- Telephone payments using debit/credit cards
- Court office payments in person
Court-Imposed Fine Payment:
- Payment terms set by court (usually 28 days)
- Instalment options available for larger amounts
- Means enquiry hearings for payment difficulties
- Enforcement action for non-payment
- Additional costs for collection proceedings
Late payment can result in increased fines, court enforcement action, and potential imprisonment in extreme cases of persistent non-payment.
Challenging Speeding Fines
Drivers have legal rights to challenge speeding allegations through established procedures, though success requires valid grounds and proper legal approach.
Valid Challenge Grounds:
- Incorrect vehicle identification
- Speed measurement equipment failures
- Procedural errors in prosecution
- Emergency or duress circumstances
- Invalid speed limit signage
- Technical defences regarding calibration
Challenge Procedures:
- Fixed penalties: Return notice within 28 days requesting court hearing
- Court cases: Enter not guilty plea and present defence
- Legal representation: Recommended for complex cases
- Evidence gathering: Obtain technical data and witness statements
- Court appearances: Present defence arguments effectively
Unsuccessful challenges typically result in higher penalties than accepting initial offers, making careful consideration essential before proceeding.

Conclusion
The UK’s speeding fine calculation system balances deterrence with fairness through income-based penalties that reflect both offence severity and individual circumstances. Understanding the three-band structure, speed thresholds, and calculation methods helps drivers make informed decisions about their driving behaviour and prepare for potential consequences of speeding violations.
The system’s complexity requires careful consideration of multiple factors including income levels, aggravating circumstances, and previous convictions. While fixed penalty notices offer straightforward resolution for minor offences, serious speeding cases involve court proceedings with potentially significant financial and licensing consequences.
Staying within speed limits remains the most effective way to avoid these penalties whilst contributing to road safety for all users. The current system ensures that violations carry meaningful consequences regardless of income level, supporting the government’s ongoing efforts to reduce speed-related casualties on UK roads.
Frequently Asked Questions
How much is a speeding fine for 35mph in a 30mph zone?
For 35mph in a 30mph zone, you’ll typically receive a Band A penalty. This usually means a £100 fixed penalty notice with 3 penalty points. If the case goes to court, the fine becomes 50% of your weekly income (minimum £120, maximum £1,000) plus the same penalty points.
Do speeding fines increase with your salary in the UK?
Yes, speeding fines are calculated as a percentage of your gross weekly income when cases go to court. Band A offences result in fines of 50% of weekly income, Band B penalties are 100%, and Band C violations cost 150% of weekly income, all subject to minimum and maximum limits.
What happens if you can’t afford to pay a speeding fine?
If you cannot afford your speeding fine, contact the court immediately to discuss payment options. Courts can arrange instalment plans or hold means enquiry hearings to assess your financial situation. Ignoring the fine leads to enforcement action, additional costs, and potentially more serious consequences.
How many mph over the speed limit before you get a fine?
There’s no legal threshold – you can be fined for any speed above the limit. However, most police forces use informal tolerance policies, typically 10% plus 2mph (e.g., 35mph in a 30mph zone). These tolerances are discretionary and not legally guaranteed.
Can you get banned from driving for speeding in the UK?
Yes, you can be banned from driving for speeding. Courts can impose disqualification periods of 7-56 days depending on the penalty band, or you face automatic disqualification if you accumulate 12 penalty points within three years through multiple offences.
