Best Pay-As-You-Go Car Insurance UK 2026

Last reviewed: 26 April 2026

What pay-as-you-go car insurance is and how it differs from annual cover

Pay-as-you-go motor insurance, also termed pay-per-mile insurance, replaces the standard annual fixed premium model with a structure that charges policyholders based on the actual number of miles they drive. The charge has two components: a fixed base premium covering stationary risk (fire, theft, third-party liability while parked) and a variable per-mile charge covering driving risk, billed at the end of each billing period based on miles recorded by a telematics device.

Standard annual motor insurance policies set a premium at inception for the full policy year based on declared annual mileage and other rating factors. The premium is fixed regardless of whether the policyholder drives 1,000 miles or 15,000 miles during the year, the declared mileage band determines the pricing, not the actual mileage. PAYG inverts this: actual mileage drives the cost, billed variably each month.

For policyholders whose actual mileage is predictably low, PAYG can produce a lower total annual cost than an equivalent annual policy. For policyholders whose mileage is high or unpredictable, PAYG typically produces a higher total cost than an annual policy.

The Road Traffic Act 1988, section 143 minimum of Third Party Only cover applies to PAYG policies identically to standard annual policies. PAYG policies are registered on the Motor Insurance Database (MID) from inception and are subject to the same FCA ICOBS conduct requirements as all other motor insurance products.

Who benefits from pay-as-you-go car insurance

The actuarial case for PAYG car insurance is strongest for drivers whose actual annual mileage is genuinely low and whose use is infrequent. Specifically:

Urban commuters who primarily use public transport: Drivers who keep a car for occasional weekend use or essential journeys, relying on public transport for weekday commuting, may drive as few as 2,000 to 4,000 miles per year. For this profile, the PAYG per-mile charges for actual miles driven may sum to less than the equivalent annual policy premium for declared low mileage.

Second-car owners: Households with a primary vehicle used for most driving and a secondary vehicle used only occasionally. The secondary vehicle's insurance cost on a PAYG basis reflects its actual infrequent use rather than a fixed premium for a full year of potential use.

Older or retired drivers: Drivers who have reduced their annual mileage significantly post-retirement, driving primarily for local errands and appointments, may find PAYG economics more favourable than an annual policy calibrated to a historically higher mileage profile.

PAYG is least suitable for: drivers with high or unpredictable annual mileage; drivers who need to make long trips regularly; and drivers for whom the telematics device installation creates a constraint (PCP or lease vehicles where OBD-II device fitting may require finance provider consent).

How the telematics device works in PAYG products

UK PAYG motor insurance products require a telematics device, typically a small plug-in unit installed in the vehicle's OBD-II diagnostic port, to record actual mileage. The device transmits mileage data to the insurer via mobile network at the end of each billing period, which triggers the variable per-mile billing.

The OBD-II port is a standardised diagnostic interface present in all UK-registered petrol and diesel vehicles manufactured after 2001 and most hybrid and electric vehicles. The device fits without vehicle modification. For electric vehicles, the OBD-II port compatibility should be confirmed with the specific PAYG insurer before purchase, as some EV platforms have proprietary diagnostic interfaces.

The mileage recorded by the telematics device is the billing basis. Policyholders cannot adjust or override the recorded mileage. Tampering with the device is a policy condition breach that typically results in cancellation. The device must remain installed throughout the policy period for cover to be valid.

Insurance Premium Tax at 12 percent (HMRC, gov.uk) applies to all PAYG premium components, both the base premium and the per-mile billing. The tax is included in the prices presented to consumers.

By Miles and the UK PAYG market structure

By Miles Limited (FRN 769339) is an FCA-authorised insurance intermediary operating a pay-per-mile motor insurance model with policies underwritten through Lloyd's of London syndicates. By Miles is among the most established PAYG car insurance brands in the UK market. Confirm current regulatory status at register.fca.org.uk.

The UK PAYG market also includes temporary insurance providers whose short-term products function as de-facto PAYG solutions for very occasional drivers, covering specific journeys rather than providing ongoing PAYG annual cover. Cuvva Limited (FRN 765322) is an FCA-authorised short-term insurance broker offering app-based hourly and daily cover. The structural difference between true PAYG annual products and short-term on-demand products matters: PAYG annual products provide continuous year-round cover with monthly variable billing; short-term products provide cover only for the specific purchased period and lapse between purchases.

BIBA-registered specialist brokers (biba.org.uk/find-insurance/) can provide access to the full PAYG and telematics market and advise on whether a PAYG annual product or an alternative (standard low-mileage annual policy, short-term cover) is most appropriate for a specific driver profile.

Comparing PAYG to standard low-mileage annual policies

The correct comparison for a low-mileage driver considering PAYG is not "PAYG versus standard market average" but "PAYG versus the most competitive standard annual policy at declared low mileage." Standard annual policies do price mileage as a rating factor, a declared annual mileage of 2,000 miles produces a lower premium than 10,000 miles from the same insurer for the same driver profile.

The actuarial difference between PAYG and a standard low-mileage annual policy is that PAYG eliminates the risk of mileage under-declaration non-disclosure. A driver who declares 3,000 miles on a standard annual policy but drives 6,000 miles is in breach of CIDRA 2012 and faces policy voidance risk. A PAYG driver who drives 6,000 miles simply pays for 6,000 miles, no non-disclosure, no compliance risk.

Key Figures

Frequently Asked Questions

Is pay-as-you-go car insurance always cheaper?

No. PAYG is cheaper than a standard annual policy only when actual mileage is low enough that per-mile charges plus the base premium sum to less than the equivalent standard annual premium. For high-mileage drivers, PAYG is typically more expensive. The break-even point is approximately 7,000 miles per year for most profiles.

Does PAYG car insurance require a device in my car?

Yes. UK PAYG motor insurance products require a telematics device, typically a plug-in OBD-II unit, to record actual mileage. The device transmits mileage data that drives variable billing. It must remain installed for cover to be valid.

Can I get PAYG insurance on a leased or PCP vehicle?

OBD-II plug-in devices do not permanently modify the vehicle and typically do not require finance or lease provider consent. Confirm with the specific PAYG insurer and the finance or lease provider before installing any device.

Is PAYG car insurance registered on the Motor Insurance Database?

Yes. All PAYG annual policies are registered on the MID from inception. Short-term PAYG-style products are registered on MID for the specific covered period only and lapse between purchases.

What happens if I drive more miles than expected on a PAYG policy?

On a true PAYG annual policy, additional miles are billed at the per-mile rate, you simply pay more. There is no penalty for driving more than initially expected; the variable billing adjusts automatically. This eliminates the mileage non-disclosure risk present on standard annual policies.
