An 18 year old in the UK typically pays somewhere between £1,600 and £2,000 a year for comprehensive cover, though it can be higher or lower depending on the car, location and cover type. This sits well above the UK-wide average of around £600 to £700 a year, because insurers treat this age group as significantly higher risk.
There’s no single official published average specifically for age 18, since most industry price indexes group young drivers together (commonly 17 to 20, or 17 to 24). Within that band, published figures for neighbouring ages give a useful guide: 17 year olds average around £1,700 a year, and 19 year olds average slightly above £2,000, so an 18 year old typically falls somewhere in that range.
A few things push the figure up or down for an individual:
The car. Insurance group matters enormously. A small hatchback in a low insurance group can bring the cost down considerably compared with a higher performance car in the same age bracket.
Where the car is kept. Postcode risk data means the same driver and car can cost noticeably more in a city than in a rural area, with London and Belfast consistently among the most expensive regions.
No claims history. An 18 year old with no driving history starts with no discount at all, which is one of the biggest single factors in the price.
Telematics. Black box policies price on actual driving behaviour rather than age alone, and a large majority of young drivers who take one out end up paying less than they would on a standard policy.
The headline figure can look alarming, but it drops fairly quickly with a clean driving record. It’s worth getting a few comparison quotes rather than assuming the “average” applies to any individual case.
Similar questions
Why does car insurance drop so much after 18? It doesn’t drop sharply right at 18 or 19, but it starts to fall noticeably from around 21, and again around 25, as insurers’ data shows accident rates declining steadily through this age range.
Is car insurance cheaper for an 18 year old with a smaller car? Yes. Choosing a car in a lower insurance group is one of the most effective ways to reduce the cost, sometimes by several hundred pounds a year compared with a higher group car of a similar size.
Does a black box reduce the cost for an 18 year old? Usually, yes. Most 18 and 19 year olds who take out telematics insurance pay less than they would on an equivalent standard policy, because the price reflects actual driving behaviour rather than age alone.
Do 18 year olds pay more for third party or comprehensive cover? Comprehensive cover is often not much more expensive, and can sometimes be cheaper, because insurers see drivers who choose fuller cover as marginally lower risk on average. It’s always worth comparing both.
