If you have a business (even home based) you can get connection vouchers for up to £3,000 to cover the cost of installing high speed business broadband. The voucher scheme can be used against a package from one of the registered suppliers in the area.
If I read it right, you can put multiple vouchers together from businesses on the same premises. This could enable business parks or multi-occupancy offices the ability to collaborate on the cost of a much bigger internet pipe.
There is a page for Plymouth with the specialist providers listed.
Seems to be a rather overlooked opportunity for business to make the most of some free money to give them high speed business broadband. So, make the most of it now and apply as soon as you can!
