Halfords will extend its Mobile Expert service to London, following its pilot in the West Midlands, Manchester and Surrey. The retailer will place five new vans in London from 30 March, which it says will cover the capital. The service means that Halfords Mobile Expert vans will be available to nearly a third of UK households. The company added that it plans to roll out between 100 and 150 vans across the UK within the next two years.
