"We have already done much to support the sector, particularly at the world class testing centre on Orkney. Yet to date in contrast to wind power, we have seen no significant commercial projects for wave or tidal power in Scotland. That has to change."

...so quite a bit of lead time before anything comes of that I suspect.

More .uk stuff:

Leases of sites for offshore windfarm sites and the like tend to fall under the purview The Crown Estate as:

The Crown Estate owns around 55% of the foreshore (between mean high and mean low water) and approximately half of the beds of estuarial areas and tidal rivers in the United Kingdom. It also owns the seabed out to the 12 mile territorial limit, including the rights to explore and exploit the natural resources of the UK continental shelf, excluding oil, gas and coal.

The Crown Estate does not own the water column, oil, gas and coal, or govern public rights such as navigation and fishery over tidal waters

Maps of round one and two sites for offshore windfarms at the above linked Crown Estates page.

Also the .uk department of trade and industry just this week announced the results of the 23rd Seaward Licensing Round for North Sea oil and gas exploration.

Interestingly that page also points to maps and documents indicate which blocks in the round overlap potential windfarm lease areas.
