Looks like the UK Govt will try to plug the gap for up to 2020, beyond which there is no clear plan on who's going to pay the bills for further investments.

After March 2019 if there’s no deal

In the event of a ‘no-deal’ scenario, the UK’s departure from the EU would mean UK organisations would be unable to access EU funding for European Regional Development Fund projects after exit day.
We are committed to ensuring that there will be no gap in funding for regional growth in the event of a no-deal. The Chancellor announced in August and October 2016 that the government would guarantee certain EU projects agreed before we leave the EU in order to provide more certainty for UK organisations over the course of EU exit. This guarantee included European Regional Development Fund projects.
In July 2018 the government extended the guarantee so that it would cover all projects, including European Regional Development Fund projects, that would have been funded by the EU under the 2014-2020 programme period. The extension means that the Ministry of Housing, Communities and Local Government, the Devolved Administrations, and HM Government of Gibraltar, will continue to sign new projects after EU exit until programme closure.
This practical measure provides additional certainty to communities, businesses and local partners, guaranteeing investment in regional growth up to the end of the current European Regional Development Fund programmes period, in the event that the UK leaves the EU without a negotiated agreement.
