Grey fleet drivers overclaiming on their mileage accounts for nearly £15,000 in overall excessive claims, according to new data. 

On average, 12 billion business miles are said to be driven by grey fleet drivers (employees that drive their own cars for business), which are estimated to be around 14 million in number and cost employers more than £5.5bn a year in mileage claims and car allowances, according to Energy Savings Trust data.

Airmax analysed mileage data over a 14-month period recorded by 146 ‘grey fleet’ drivers. Analysis revealed that almost 78% of the journeys recorded showed a level of intentional or unintentional overclaim of mileage that accounted for nearly £15,000 in overall excessive claims (using an average PPM rate of £0.11 per mile - £7.21 can be saved per driver per month).

Airmax Remote claims that, “historically, grey fleet drivers can be hard to manage in respect of mileage claims, as drivers tend to round-up their mileage readings which creates an overall inaccurate and thereby expensive issue for businesses operating grey fleets.”

However, it has found a reported drop in ‘inaccurate’ mileage claims when using Airmax Remote’s new grey fleet remote mileage manager with integrated Google Maps.

Airmax Remote's managing director Richard Perham said: "This is a large step forward to help plug the gaps between actual and recorded mileage data, which means we can help businesses with grey fleet and company cars to realise significant  savings.”
