COMPANIES have to take a holistic approach to reviewing car provision as changing one area is likely to have a knock-on effect in another.

Harvey Perkins, a director at KPMG, said the whole fleet policy had to be constantly reviewed. If a company cut the cost of funding fleet cars, then it should consider reducing the size of payments for cash-for-car drivers, to avoid skewing provision unfairly in favour of one or the other.

Buying versus leasing should be an important consideration, the relative benefits of petrol or diesel options, and the validity of structured ECO schemes, which are now under HM Revenue & Customs review.

Perkins said: ‘It takes months to do this properly, looking at all the issues. It’s something you should be taking very seriously.’
