The Cheapest Ways to Get Insured for Under 24 Hours in the UK

If you need motor cover for less than a day, you have more options than the obvious "buy hourly insurance on an app." Some of them are much cheaper. Some only apply to specific situations. This article runs through all seven, in rough order of typical cost — cheapest first.

1. You're already covered (check first!)

Typical cost: £0.

Before you spend anything, check three documents:

• Your existing annual car insurance policy. Older policies sometimes include a "driving other cars" (DOC) extension that gives you third-party cover when driving someone else's vehicle. This has largely been phased out, but if you have a policy more than ~5 years old, check.
• The car owner's annual policy. They might already have you down as a named driver, especially if you live in the same household.
• A dealer drive-away policy if you just bought from a dealer. Many UK dealers give 5–7 days of third-party cover with a purchase. The keys are sometimes handed over without anyone mentioning this — ask.

If any of these covers you, you're done. The single biggest mistake in this category is paying for cover you already had.

2. Named driver on the owner's policy — pre-arranged

Typical cost: £0 for one-off short use; small annual premium increase if added permanently.

If you'll be borrowing the same car more than a few times a year, ask the owner to add you to their annual policy as a named driver. Most insurers allow this online with no fee, and the annual premium bump is usually £30–£80. For 5+ borrows over a year, this is the cheapest route on a per-trip basis.

The catch: a fault claim by you affects the owner's no-claims bonus. That's the structural reason temporary cover exists — it's NCB-protective for the owner. For a one-off borrow, see option 4 below.

3. Hourly cover (1–4 hours)

Typical cost: £8 – £20.

The classic "buy on your phone, certificate in your inbox in 30 seconds" temporary policy. Hourly cover is at its most cost-effective for windows of 1–4 hours — long enough to amortise the fixed admin cost in the price, short enough not to be paying for a full day.

Cheapest for: drivers under 35 in mainstream cars, where the underwriters' pricing algorithms are most competitive.

Pro tip: a 4-hour policy is often only £2 more than a 1-hour one. If you're "pretty sure" 1 hour is enough but might run over, buy 4. The peace of mind is worth the £2.

4. Daily cover (a single 24-hour policy)

Typical cost: £18 – £35.

If you need more than ~6 hours, you're typically better off on a 24-hour policy than two consecutive shorter ones. The fixed admin cost is paid once instead of twice.

Cheapest for: any "I need it for the day" situation — moving day, a wedding, a one-day road trip, collecting a piece of furniture from a town 40 miles away.

A daily policy also gives you breathing room. If you'd planned a 4-hour borrow but get held up at lunch, you're not racing the certificate clock home. For most "I think I need a few hours" jobs, the daily window costs barely more than a 4-hour one and removes a real stress factor.

5. Pay-by-the-mile cover (if you qualify)

Typical cost: variable, often £0–£10 for short trips if already enrolled.

A small but growing segment of the UK market sells annual policies priced as a small fixed monthly cost plus a per-mile charge. If you'd otherwise be buying multiple temporary policies over a year for a car you own, this can work out cheaper.

Cheapest for: low-mileage car owners who'd otherwise self-insure-by-not-driving.

Limitation: it's your car, not borrowed. You can't pay-by-the-mile for a friend's car.

6. Annual cover for the new car you just bought

Typical cost: equivalent to ~3–5 days of temporary cover for the first 24 hours, then £0 incremental for the rest of the year.

This is a counter-intuitive one. If you've just bought a car and you're definitely keeping it, starting an annual policy today is often a better deal than buying 24-hour cover and then setting up annual cover tomorrow. The temporary policy is pure overhead — you pay for it once and it expires.

Cheapest for: anyone who's bought a car they intend to keep.

Don't pick this option if: you might return the car within a few days. Annual policies have a 14-day cooling-off period but admin fees often eat the savings, and a cancelled policy still has to be declared on every future quote.

7. Drive-away cover from a dealer

Typical cost: £0 (included in purchase price).

Worth listing separately because it's so often overlooked. If you're buying from a dealer:

• Always ask before you leave.
• The 5–7 days of cover is usually third-party only, so don't crash the new car on the way home.
• It's plenty of time to set up proper cover from home.

Don't apply if: private sale or auction purchase.

The "free" options that aren't actually options

A few "free" routes that come up in online discussions and that you should not use:

• "My friend's policy covers me to drive their car." No, it doesn't, unless you're a named driver on it. Verbal permission from the owner doesn't create insurance cover.
• "I'll drive uninsured for 10 minutes, it's a short trip." £300 fine, 6 points, ANPR cameras read every plate they see. The chance of getting away with it in 2026 is essentially zero, and the consequences are disproportionate. An IN10 conviction on your record will compound across years of higher annual premiums afterwards.
• "I'll borrow my parents' DOC cover." Almost no recent annual policies include DOC any more, and the ones that do almost always restrict it to third-party only, on a car not owned by the named driver. Check the policy wording in writing — verbal "yes, you should be fine" isn't an insurance certificate.

Combining options

You can sometimes combine these to drive the cost down further. A common pattern:

1. Drive-away cover from the dealer for the trip home (£0).
2. Hourly cover the following weekend when you need to nip to the supermarket (£12).
3. Annual cover starting in 7 days so you've had time to compare quotes properly (best annual price).

Combined cost: significantly less than rushing into annual cover at the dealer forecourt, which is what dealers often pitch you because they get a commission.

How to actually get the cheapest hourly quote

Three small habits:

1. Quote at least two providers, or use a consultancy that searches a panel for you. The gap between cheapest and most expensive for the same risk is regularly 20–35%.
2. Don't over-buy duration. If you genuinely need 2 hours, don't buy 24. The reverse is also true — see option 4.
3. Don't quote on Friday evening unless you have to. Underwriters' pricing engines respond to demand patterns; Saturday morning, when half the country is borrowing each others' cars, is genuinely a more expensive time to be quoting than Tuesday at 11am.

Habit (1) does most of the work. The other two are marginal.

Worked example: borrowing a friend's car for 6 hours

Putting all of the above together, here's how a sensible decision tree runs for a typical situation:

• Do you have a named-driver arrangement? No.
• Does your own annual policy have DOC? No (it's from 2024).
• Has the friend offered to add you to their policy temporarily? No — they're protective of their 9-year NCB.
• Is it a one-off? Yes.

That points squarely at a 6-hour temporary policy on their car, in your name. Quote two providers (or one consultancy that searches the panel) and pick the cheaper. Typical cost: £14–£22. That's the answer for the overwhelming majority of "I need a car for a few hours" situations.

What changes if you're under 25?

The cheapest path for under-25 drivers is structurally different. Two specific things:

• Hourly cover is relatively more expensive for under-25s. The underwriter is pricing the higher risk; per-hour, you'll pay roughly 2–3× what an over-30 driver pays.
• A 24-hour policy is often disproportionately cheap for under-25s — the fixed admin cost is a larger share of the price, so stretching cover length spreads it more efficiently.

If you're a young driver, default to "buy 24 hours unless I genuinely only need 1". Done right, you'll often find a 24-hour policy is only £8–£10 more than a 3-hour one.

Bottom line

The cheapest sub-24-hour cover is the cover you didn't realise you already had. If that's not an option, hourly or daily cover via a panel-searching consultancy is usually the right answer — and you should never go to the first brand that comes to mind without quoting an alternative. The 90 seconds you spend on a second quote regularly pays for itself many times over.
