Why Is Temporary Car Insurance So Expensive?
Covrly Editorial Team · October 7, 2026 · 7 min read
Temporary car insurance can seem expensive because every policy has fixed setup costs squeezed into a short period, and it's often bought by drivers insurers see as higher risk, in cars they don't usually drive. The price also depends on the same factors as annual cover: your age, the car's insurance group, your postcode and your driving history. Per day it costs more, but you're only paying for the time you need.
Let's unpack what's going on behind the number, and what you can realistically do about it.
How much does temporary car insurance cost?
There's no single answer, because quotes are personal. As a reference point, Uswitch reported an industry average of about £74 per temporary policy between October 2022 and September 2023. That figure covers all sorts of drivers, cars and policy lengths, so your quote could land well above or below it.
The more useful question is why your particular quote looks the way it does.
Why is temporary car insurance so expensive per day?
1. Fixed costs don't shrink with the policy
Whether a policy lasts one hour or thirty days, someone still has to run checks, price the risk, issue the documents and add the policy to the Motor Insurance Database. Those costs are roughly the same either way. On a short policy, they're packed into a small window, so the daily rate climbs.
2. Short-term risk is concentrated
People tend to buy short-term cover for specific, often busier, situations: a long road trip, a house move, a weekend away, collecting a newly bought car. That's a lot of driving in a short space of time, often on unfamiliar roads, so the risk per day is higher than the average day of an annual policy, which includes plenty of days when the car just sits on the drive.
3. Unfamiliar cars
Driving a car you don't know well, with different controls, size and handling, carries a bit more risk than driving your own. Insurers factor that in.
4. Who's buying it
A large share of short-term cover is bought by younger drivers, newly qualified drivers and learners, who statistically make more claims. If you're in one of those groups, that's reflected in your price. Our young drivers guide goes into more detail on how age affects the price.
What affects the price of your quote?
These are the main factors insurers weigh up:
- Your age. Younger drivers typically pay more. Prices usually ease as you get older and more experienced.
- How long you've held your licence. A newly qualified driver generally pays more than someone with years of experience.
- The car's insurance group. UK cars sit in groups 1 to 50. A small hatchback in a low group costs less to insure than a powerful car in a high group.
- The car's value and repair costs. Comprehensive cover pays for damage to the car you're driving, so pricier cars and pricier parts mean pricier cover.
- Your postcode. Areas with higher rates of theft, vandalism or accidents usually mean higher premiums.
- Your driving record. Recent convictions, penalty points or claims tend to push quotes up.
- How long you need cover. Longer policies cost more in total but usually less per day.
Does the length of cover change the price?
Yes, and not always in the way people expect. A longer policy costs more in total, because you're covered for more driving. But the price per day usually drops as the policy gets longer, because those fixed costs are spread across more days.
That has a practical upshot. If you know you'll need a car on a Friday and again the following Wednesday, two separate one-day policies might cost more than a single policy covering the whole week. Equally, a whole week is poor value if you only drive once. It's worth pricing a couple of options before you buy.
The other side of this is timing. Cover needs to be in place before you drive, and it ends at the exact time shown on your certificate. Building in a sensible buffer for the return journey is better than having to buy a second policy because you were stuck in traffic.
Is temporary car insurance worth it?
Often, yes, especially compared with the alternatives. If you only need to drive a car occasionally, the options are usually:
- Adding yourself as a named driver to the owner's annual policy, which may include an admin fee, keeps you on the policy all year, and puts any claim on their record.
- Relying on "Driving Other Cars" cover from your own policy, which many policies no longer include and which is usually third-party only.
- Driving uninsured, which is illegal. The penalty is a £300 fixed penalty and 6 points, and if it goes to court you could face an unlimited fine, disqualification and the car being seized.
Against those, a short, fully comprehensive standalone policy that leaves the owner's no-claims discount untouched can be good value, even if the daily figure looks high. For a fuller comparison, see annual vs temporary car insurance.
Practical ways to pay less for temporary car insurance
You can't change your age, but there's still plenty within your control:
- Only cover what you need. If you need the car for an afternoon, look at hourly cover rather than a full day. If it's a weekend, don't buy a week "just in case".
- Pick the right car if you have a choice. If two family cars are available, the one in the lower insurance group is likely to be cheaper to insure.
- Check longer durations. If you'll need the car several times in a fortnight, one longer policy may cost less than several short ones.
- Be accurate. Getting details like your licence type, address or the car's registration wrong can lead to problems if you claim. Accurate details give you a quote you can actually rely on.
- Keep your record clean. Points and convictions affect what you pay, often for several years.
- Avoid modified cars where possible. Modifications usually need declaring and can raise the price.
- Compare like with like. Some cheaper-looking policies are third-party only or have a much higher excess. Covrly policies are fully comprehensive, so check what you're comparing against.

What not to do to save money
A few "hacks" can cost you far more than they save:
- Don't give false information. Misrepresenting your age, address, licence or the car's use can invalidate your cover.
- Don't buy from unverified sellers on social media. Policies that look suspiciously cheap may be "ghost broker" scams, leaving you uninsured without knowing it. Our guide on whether temporary car insurance is legit explains how to spot them.
- Don't let cover lapse mid-trip. If your plans run over, buy a new policy before the old one ends. Driving even a few minutes after expiry means driving uninsured.
The bottom line
Temporary car insurance looks expensive per day because fixed costs and concentrated risk get packed into a short window, and because the drivers who use it most are often those insurers price higher. But you're paying for exactly the time you need, with no long-term commitment and no impact on the owner's policy.

Frequently asked questions
How much does temporary car insurance cost on average?
It varies widely depending on the driver, the car, the location and how long you need cover for. As a rough benchmark, Uswitch reported an industry average of about £74 per temporary policy between October 2022 and September 2023. Your own quote could be higher or lower than that.
Why does a one-day policy cost more per day than a week?
Every policy has fixed costs, such as checks, setup and issuing documents, regardless of how long it runs. On a one-day policy, all of those costs fall on a single day. On a longer policy, they're spread out, so the daily figure usually drops.
Does the car I'm borrowing affect the price?
Yes. Cars are placed in insurance groups from 1 to 50 based on things like repair costs, performance and security. A car in a higher group generally costs more to insure, whether on an annual or a temporary policy.
Is it cheaper to buy temporary car insurance in advance?
Not necessarily, as pricing depends on many factors. What does help is getting a quote with accurate details and only covering the time you really need, so you aren't paying for spare days.
Will lying about my details make temporary insurance cheaper?
It might lower the quote, but it can also invalidate your policy, leaving you effectively uninsured and personally liable if something goes wrong. Always give accurate information about yourself, the car and how you'll use it.
