A 21 year old in the UK pays between £723 in South West England and £1,306 in London per year for car insurance, depending on where they live. In London, that is less than half the average at 17, thanks to four years of driving experience and up to four years of no-claims bonus.

London remains the most expensive region for 21 year old drivers, with average premiums 81% higher than the South West. In pounds, the gap between the cheapest and most expensive regions is the smallest of any age from 17 to 21, as the young-driver premium starts to level out.

21 is a quiet milestone for car insurance. The average premium typically drops between 20 and 21, but the price change matters less than the wider set of options that become available.
Turning 21 typically unlocks:
At the same time, most insurers still classify you as a young driver until 25. The step change to standard pricing typically happens around that age.
Final year university students at 21 should always register their car at the address where it is kept most often. If your car stays at your parents' home rather than near campus, this could result in a lower premium, as postcode is one of the biggest rating factors. University towns may carry a higher risk loading than suburban home addresses. See our student car insurance guide for more information.
At 21 with four years of NCB, drivers can start moving into groups 5 to 20 without a huge premium jump. This unlocks more of the mainstream new-driver-friendly car market: family hatchbacks, small SUVs, and hybrid options.
Popular cars in groups 5 to 20 for 21 year olds include:

By 21 you have real bargaining power. Four years of clean driving history means you can compare a full slate of insurers and pick a policy that fits your life.
Building a no claims bonus as a young driver is the single most effective long-term way to keep your premium down. Five years of NCB by 22 typically unlocks the maximum discount most insurers offer.
At 21, temporary car insurance is easy to find. The main under-21 age gates that some providers use no longer apply. Short-term policies from 1 hour to 28 days are readily available for driving a borrowed car, sharing a road trip, or moving a used car home from a private seller.
Common uses at 21:
See our temporary car insurance guide for what is available and how the prices compare.
25 is the next big milestone. Most UK insurers may reclassify drivers out of the young-driver risk band around 25, which could result in a noticeable drop in premiums for drivers with a clean claim history.
See our car insurance over 25 guide for what changes at 25 and the regional data for that age band.
