TL;DR
Personal cover follows the driver across any vehicle. Vehicle-based cover is tied to a specific car regardless of driver. Personal cover costs £15 to £30 more per year but is cheaper for households with multiple drivers or vehicles.
The decision turns on three factors: number of vehicles in the household, number of drivers needing cover, and how often household members drive non-household vehicles (parents' cars, hire cars, friends' vehicles). Personal cover wins for two or more drivers or two or more vehicles.

The structural difference
Vehicle-based breakdown cover is tied to a specific named vehicle. The cover responds when that vehicle breaks down, regardless of who is driving it (subject to the driver being legally entitled to drive). The cover does not respond when the named driver is in any other vehicle.
Personal breakdown cover is tied to the named driver. The cover responds when the named driver breaks down in any vehicle, subject to standard policy terms (vehicle weight limits, exclusion list). The vehicle being driven does not need to be named on the policy.
Both products have the same scope of cover at each tier (roadside, home start, recovery, onward travel, European). The difference is purely the trigger for the policy to respond.
When personal cover is the cheaper option
Households with two or more vehicles. A two-car household with vehicle-based cover needs two policies, one per vehicle. Two policies at £55 each is £110. A single personal policy covering one driver across both cars at £75 is £35 cheaper. The maths gets stronger with more vehicles.
Two or more drivers needing breakdown cover. A couple where both drive both household cars needs four trigger points (driver A in car 1, driver A in car 2, driver B in car 1, driver B in car 2). Two personal policies cover all four trigger points and total £150. Two vehicle policies also cover all four but the cost is similar; the personal policies additionally cover both drivers in hire cars, friends' cars, and any other vehicle.
Frequent driving of non-household vehicles. University students driving parents' cars at term-time and back home, drivers who frequently hire vehicles, drivers who borrow friends' cars, all benefit from personal cover because vehicle-based cover does not respond.
When vehicle-based cover is the cheaper option
Single vehicle household with a single primary driver. Vehicle-based cover is the cheaper product. Personal cover adds £15 to £30 per year for benefits that will not be used.
Multiple drivers all of whom are named on the same vehicle's policy. Vehicle-based cover responds for any named driver. If the household never drives non-household vehicles, this is cost-effective.
High-value primary vehicle, secondary vehicle rarely used. Vehicle-based cover on the primary vehicle plus pay-on-use cover for the secondary may be cheaper than two policies or one personal policy. The maths depends on the secondary vehicle's annual mileage and breakdown likelihood.
Pricing comparison at the major providers in 2026
For a 40-year-old driver, mid-range vehicle, 5 years old, urban postcode, full cover (roadside, home start, recovery, onward travel):
Green Flag. Vehicle-based £65, Personal £80. Difference £15.
AutoAid. Vehicle-based £55, Personal £65. Difference £10. AutoAid is the closest-priced provider on the personal premium.
Start Rescue. Vehicle-based £55, Personal £75. Difference £20.
RAC. Vehicle-based £100, Personal £130. Difference £30.
AA. Vehicle-based £120, Personal £150. Difference £30.
The £15 to £30 personal premium translates to break-even at one extra non-household vehicle journey per year if a breakdown occurs in it (callout cost without cover £150 to £350).
Edge cases worth knowing
Named driver versus policyholder. Personal cover usually covers the named policyholder. To cover a partner, the partner is named on the same policy at small additional cost (£15 to £40), or buys a separate personal policy. Some providers (AutoAid) offer joint personal cover at a single bundled price.
Hire car cover. Personal cover responds in hire cars subject to the hire car meeting the policy's vehicle exclusion list (typically excluded are vehicles over 3.5 tonnes, vehicles over a specified value, vehicles being used for commercial hire-and-reward). Check the small print before relying on personal cover for hire vehicles.
Caravan and motorhome interaction. Personal cover does not generally extend to caravans being towed by the named driver; caravan cover is a separate product. Motorhomes driven by the named driver may be covered subject to weight limits.
Frequently asked questions
What is the difference between personal and vehicle breakdown cover?
Personal cover follows the named driver across any vehicle they drive. Vehicle cover is tied to a specific named vehicle and responds regardless of who is driving it. Same scope of cover at each tier; different trigger.
Is personal breakdown cover worth the extra cost?
For households with two or more vehicles, two or more drivers, or frequent driving of non-household vehicles (university students, hire car users), personal cover is consistently cheaper than equivalent vehicle-based cover. For a single-driver, single-vehicle household, vehicle-based cover is cheaper.
Does personal breakdown cover work in a hire car?
Yes, subject to the policy's vehicle exclusion list. Most personal cover excludes vehicles above 3.5 tonnes, above a specified value, and commercial hire vehicles. Standard rental cars within the exclusion list are covered.
Can I add my partner to personal breakdown cover?
Yes. Most providers offer joint cover for a small additional cost (£15 to £40 per year). AutoAid bundles joint personal cover at a single price. Check whether the partner needs to share an address.
Is AA membership personal or vehicle?
AA Membership is sold as both personal and vehicle-based cover at different tiers. Personal AA Membership covers the named member in any vehicle (subject to exclusions); vehicle-based AA breakdown cover applies to the named vehicle only.
