PHH says now the 6% increase in pump prices has filtered through to the UK forecourts, an average 100-vehicle fleet will see fuel bills rise by more than £10,000. But, it claims that by using MPG Improvement Reporting, the same fleet could see a fuel bill reduction of at least 10%, leaving it £4,500 better off than before the Budget.

PHH divisional manager, fuel, Keith Greenhead, said: 'The majority of drivers should be able to make an improvement of between two and three mpg without any difficulty. Two miles alone is enough to offset Budget increases. Everything over this is a clear and obvious saving.'
