The Tourism Investment Support Scheme(TISS) is open for both existing and new tourism businesses in Wales.  

Support is available for the purpose of upgrading the quality of facilities and increasing capacity where there is a gap in the market. We are also encouraging businesses to show how aspects of the planned development will directly benefit energy efficiency or environmental improvement.

Projects costs from £5,000 to half a million are eligible, although support over £25,000 maybe repayable. Full details here
