Family fleet insurance works in much the same way as standard cover, except you take out just one policy for several vehicles. You get a discount for insuring multiple cars. The savings vary from insurer to insurer, but normally about 20% off what you would otherwise spend.
Multi-car policies typically cover between two to five vehicles. Most insurers need all the vehicles involved are registered to the same address, they can include cars, vans, motorcycles and campervans. Anything, really, apart from commercial and company cars.
**Check the policy terms and conditions before you buy to find out what is covered, and what you will need to add.
