Proposals in this week's Chancellor's Budget to consider a four year wait until a vehicle's first MoT test have been criticised by the chief of Warranty Direct.

Currently vehicles require an MoT test at three years since registration, but George Osborne said the Government will consider changing this to four years.

Warranty Direct warned that moving away from the traditional three-year MoT test to a fourth birthday safety check will mean essential maintenance is postponed, while motoring costs could actually increase.

The first MoT failure rate is also set to rocket from the typical 20%, with more components likely to be identified as requiring attention, it said..

David Gerrans, Warranty Direct managing director, said: “Three years of age is generally a landmark age for a car. In most cases, it stops being covered by the manufacturer’s warranty and things start going wrong and wearing out.

“Whilst adding another year before an MoT is due is a nod to manufacturer build quality, it could be viewed as detrimental to road safety, as the average driver will need to replace tyres and brakes before the four year mark.   

“Extending the deadline for the first MoT of new cars from three to four years, will only encourage motorists to postpone necessary maintenance work for anything up to an extra year, potentially putting the driver and other motorists at risk.”
