The insurance giant is warning young drivers that they could lose around £2,000 typically by buying a fake motor insurance policy.
The insurer said young drivers aged 17 to 25 are the primary target of ghost brokers.
Its data indicates that, on average, young drivers are losing £2,000 each when they buy fake car insurance policies from ghost brokers.
This includes the average premium paid to a ghost broker (£1,700) and the extra fees (£300) charged by ghost brokers selling fraudulent policies.
Aviva said ghost broking detections are running higher this year than in 2024.
A strong set of results, with more still to come.

Ghost brokers are not real insurance brokers but criminals luring motorists in with fake policies that appear cheap.
They may produce insurance documents that are entirely fake and bypass legitimate insurers completely, or falsify someone’s details to artificially bring down the cost, or take out a genuine policy but then cancel it.
Often people do not realise their insurance is fake until they are stopped by police or involved in an accident.
As well as the average £2,000 loss to the fraudsters, people with a fake policy could face being liable for costs for any injuries or damage caused while driving without cover, having their car seized by the police, and court action.
“People may also end up being victim to identity fraud if the criminals sell their personal details on.
Many scams start on social media and Aviva said it has identified a sharp rise in ghost broking scams using fake, professional-looking websites that impersonate legitimate insurers.
Owen Morris, UK personal lines chief executive at Aviva, said, “Ghost broking is a fast-growing criminal enterprise that targets young drivers on social media sites.
“These fraudsters exploit social media to sell worthless insurance, leaving victims thousands of pounds out of pocket, driving without insurance, and at risk of prosecution. They could also potentially be victims of identity or banking frauds in the future.
“The scale of the problem is concerning – and it’s getting worse.”
Aviva suggests the following to avoid falling victim to ghost brokers:

- Be cautious about anyone selling insurance on social media.
- Verify who you are dealing with. Contact insurers directly and check the Financial Services Register. Check registrations with the British Insurance Brokers’ Association (Biba) and the Financial Conduct Authority. Biba can help young drivers, who often pay more for their policies, to find legitimate insurance.
- Anyone suspecting they have been a victim of ghost broking or other fraud should report their concerns to the police.
He added: “Our message to young drivers is simple: Before buying insurance on social media, always check the seller is genuine before you pay.”
