It will allow leaders of the sites to explore opportunities to cut costs, increase efficiently and for joint marketing.
Geoff Taylor, of Chain Bridge Forge, said: “We’re hoping to find ways to be more efficient, save a little bit of money and run better.
“It’s important to continually look for new ideas to encourage people to come back and support you.”
The grant will allow consideration of a vast array of joint or shared resources.
Investigations will include exploring possible ways to share governance, management and volunteer recruitment and training arrangements.
In addition it will enable reviews of customer experiences and how they can be improved, ways to reduce duplication and make each site sustainable.
There will be a chance to look at how the sites are marketed and further support them to be self-funding.
