THE Energy Saving Trust (EST) has called for the differential between VED bands to increase and experts say the tax could rise to £900 per year on vehicles achieving less than 35mpg.

However, an EST spokeswoman said: ‘VED needs to increase but we cannot put a figure on how much to increase it by.

‘The figures released are based on MORI research and are not our proposition.’
