Motoring costs rise on the Continent Since 2007, the cost of a litre of fuel has increased by up to 82 per cent on the Continent, with Italy, France, Spain and Switzerland now offering the worst value for motorists, according to research conducted by the Post Office. Motorists can now expect to pay £1.37 a litre, up 82 per cent on 2007, in Switzerland, while the popular destinations of France, Spain and Italy have seen increases of around 60 per cent over the five-year period. According to the survey, British holidaymakers remain undeterred, with only eight per cent of respondents saying the high fuel prices would put them off taking their car to Europe. However, the strength of sterling against the euro has seen a fall in pump prices for British holidaymakers when compared with 2011. The countries offering the best value for motorists were Luxembourg and Andorra, but drivers to Italy will find the cost of a litre of diesel up 10 per cent on last year to £1.49 per litre. Drivers of diesel cars will find the cost of filling up cheaper on the Continent than in Britain. "Our research shows that UK holidaymakers are not deterred by the high fuel prices they will find when driving in some countries this summer," said Andrew Brown, the Post Office's head of travel money. However, it also revealed that some advance route planning with petrol prices in mind could help them cut costs. A good tip is to fill up before leaving the UK if travelling to France or Belgium in a petrol car, divert into Luxembourg if travelling south through eastern France or detour into Andorra en route to Spain. If you are driving a diesel car, fill up as soon as you arrive on the Continent as it is much cheaper in Europe than in the UK.
