The Department for Transport has spent £800,000 on Brexit consultants while the Border Delivery Group spent £10.2m, according to a report by the National Audit Office.
In total, the NAO found that the government has spent at least £97 million on consultancy services to pave the way for exit from the EU.
Top spender is the Cabinet Office, at £12.4m, followed by £10.2m spends at the Home Office as the Border Delivery Group (a cross-government team hosted by HMRC).
The NAO said: “Preparing for the UK’s exit from the EU has been a significant challenge for departments and has required skills such as project delivery and commercial skills that are in short supply.”
Six consultancies account for 96 per cent of the government’s Brexit work. These are: Deloitte (22 per cent); PA Consulting (19 per cent); PricewaterhouseCoopers (18 per cent); Ernst & Young (15 per cent); Bain & Company (11 per cent); and Boston Consulting Group (10 per cent).
