GOV.UK Verify will be the single identification service for individuals. The authentication service that HM Revenue and Customs (HMRC) is developing to replace the Government Gateway will complement the existing GOV.UK Verify service for business representatives.
HMRC agreed with the Cabinet Office and Department for Work and Pensions to take on responsibility for decommissioning the existing Government Gateway, in line with current contractual arrangements, by March 2018. HMRC and the Government Digital Service are working with government departments to help them find suitable solutions beyond that point.
The cost of building a replacement Gateway service is commercially sensitive information, and so cannot be provided.
