Best car insurance for cheaper rates
The average motor insurance premium rose by nearly 8% during the 2023, to hit £786, according to recent analysis by research firm Consumer Intelligence. This makes it even more important to shop around. The cheapest policy for one driver might not be cheapest for another, because insurers price risk in different ways (risk is calculated using your driving history and personal details). But some providers tend to offer good rates.
