SP50 motorway speeding car insurance in the UK (2026)

An SP50 motorway-speeding conviction adds around +20% to a UK car insurance premium on average in 2026 — about £140 a year, taking a typical £700 comprehensive policy to roughly £840, and more in the first year. SP50 is the DVLA code for exceeding the speed limit on a motorway, and carries 3 to 6 penalty points (3 is typical) plus a fine of up to £2,500. The points stay on your licence for 4 years from the conviction, and insurers can see them for the duration.

Direct Answer

What SP50 means and what it does to your premium

SP50 is the DVLA endorsement code for exceeding the speed limit on a motorway — almost always the national 70mph limit, or a lower variable limit shown on the overhead gantries of a smart motorway. It carries 3 to 6 penalty points, with 3 being the usual penalty for a modest excess; the points rise towards 6, and a short disqualification becomes possible, the further over the limit you were. The fine is means-tested as a percentage of weekly income (Band A, B or C) and can reach £2,500 on a motorway — higher than the £1,000 cap that applies to non-motorway roads.

The points stay on your licence for 4 years from the date of conviction, and insurers can ask about them for that whole period. Insurers treat an SP50 a little more seriously than an SP30 (speeding on an ordinary road), because high motorway speeds carry a greater risk of a severe, multi-vehicle collision. In practice a single 3-point SP50 adds around +15% to +25% to a premium — we model an average of about +20%, roughly £140 on a £700 policy — while a 6-point SP50, or one combined with other points, can push the loading higher. Here is how the cost typically eases as the conviction ages:

How It Compares

SP50 versus the other speeding codes

All SP codes are speeding offences, but the road and vehicle type change the code — and insurers price them slightly differently. SP50 (motorway) and SP30 (ordinary road) are by far the most common. This is how the family compares:

CodeOffenceTypical pointsTypical insurance loading
SP10Exceeding goods-vehicle speed limit3–6+15–25%
SP20Exceeding limit for vehicle type (not goods/passenger)3–6+15–25%
SP30Exceeding the limit on a public road3–6+12–20%
SP40Exceeding passenger-vehicle speed limit3–6+15–25%
SP50Exceeding the limit on a motorway3–6+15–25%

The practical takeaway: a single SP50 is a manageable, mainstream-insurable conviction — every standard insurer still quotes — but it is treated marginally more seriously than an SP30, and the loading climbs sharply if the points reach 6 or if it is your second speeding offence.

How to Lower It

Six legitimate ways to cut SP50 insurance cost

  1. Take a speed-awareness course if offered — for a borderline excess, police may offer a National Speed Awareness Course instead of points. Completing it means no SP50 and no insurance loading at all, though some insurers ask whether you have taken one. It is the single best outcome where eligible.
  2. Compare widely, every renewal — SP50 loadings vary between insurers; the cheapest insurer for a clean driver is rarely cheapest with a conviction, so run several comparison sites and re-quote annually.
  3. Drop to a lower insurance group car — moving from a group 25 car to a group 8–12 city car can cut a post-conviction premium by 30–40%, because the insurer stacks the SP50 loading on the car's base rate.
  4. Raise your voluntary excess — going from £250 to £500–£750 voluntary excess typically trims 8–15% off, provided you can fund the excess if you claim.
  5. Pay annually, not monthly — monthly instalments on a loaded premium carry APRs of 20–40%; paying the year up front avoids those finance charges.
  6. Keep your record clean and let time work — the loading falls every year and the points leave your licence at four years. A single SP50 fades quickly; a second speeding conviction within a few years is what pushes you towards a heavy loading or the totting-up ban at 12 points.

Never be tempted to not declare the conviction to get a cheaper price — non-disclosure of an SP50 voids the policy, leaves you uninsured at the moment of a claim, and is itself an offence. The legitimate route is the awareness course where offered, wide comparison and time.

Common Questions

SP50 car insurance FAQs

A single 3-point SP50 motorway-speeding conviction adds around +20% on average to a UK premium in 2026 — roughly £140 on a typical £700 comprehensive policy, taking it to about £840 — with year-one quotes often nearer +40%. The exact figure depends on your age, the car's insurance group, where you live, how many points were imposed and whether you have other convictions. A 6-point SP50, or an SP50 on top of existing points, carries a higher loading. The increase falls steadily each year and is largely gone by the fifth year.
SP50 points stay on your driving record for 4 years from the date of conviction, after which the DVLA removes them. Insurance is different: insurers normally ask about convictions in the last 5 years, so you may need to declare an SP50 for 5 years even though the points have left your licence at year four, and a few insurers ask about a longer period. Always answer the exact question the insurer asks rather than assuming the 4-year licence rule applies to the declaration.
An SP50 carries between 3 and 6 penalty points. Three points is the usual penalty for a modest excess dealt with by a Fixed Penalty Notice. The points rise towards 6 — and a short discretionary disqualification becomes possible — the further over the limit you were travelling; very high motorway speeds are often referred to court, where a ban can be imposed instead of, or as well as, points. New drivers should note that reaching 6 points within two years of passing means the licence is revoked.
Sometimes. For a borderline motorway excess (typically up to around 86mph in a 70 limit) and if you have not taken a course in the previous three years, the police may offer a National Speed Awareness Course instead of points. Completing it means no SP50 endorsement and therefore no insurance loading — the best possible outcome. The course is not available for higher speeds, which go straight to a Fixed Penalty Notice or court. Some insurers ask whether you have completed a course, so answer honestly, but it does not carry a points loading.
Marginally, yes. SP50 (motorway) and SP30 (ordinary road) both carry 3–6 points and are both mainstream-insurable, but insurers tend to load an SP50 a little more heavily — around +15% to +25% versus roughly +12% to +20% for an SP30 — because high motorway speeds carry a greater risk of a severe, multi-vehicle collision. The difference is small for a single 3-point offence and both fade on the same 4-year timetable. The number of points and any repeat offences matter far more to your premium than which speeding code it was.
Yes — if the insurer's question covers the period of your conviction, you must declare the SP50, the conviction date and the points. Failing to disclose is non-disclosure: the insurer can void the policy from inception, refuse any claim, and treat you as having driven uninsured — far more costly than the higher premium. This applies even mid-term: if you receive an SP50 during a policy year, tell your insurer rather than waiting for renewal. If you are unsure whether a question applies, declare it.
A conviction and a no-claims discount are separate things. An SP50 on its own does not wipe your accumulated no-claims years — those are tied to at-fault claims, not convictions — so if the speeding did not involve an accident, your NCD is intact and the insurer simply applies a conviction loading on top of your discounted premium. If the speeding led to a crash, the resulting at-fault claim is what reduces your NCD, not the SP50 code itself. Keep proof of your no-claims years to present at quote.
Premiums improve steadily from the second year and are broadly back to normal once you no longer have to declare the conviction — typically the sixth year, five years after conviction. The biggest single drop comes once the points leave your licence at four years. Keeping a clean record and re-quoting widely at every renewal both speed the recovery. Note the gap between the points leaving your licence (4 years) and the conviction no longer being declarable to insurers (commonly 5 years) — the full insurance benefit lands when that declaration window closes.
