The UK currently has about 15GW of grid wind power (and maybe 4-5GW privately owned that is not attached to the grid it's just used to avoid buying grid electricity). There is no reason whatsoever that can't be 45GW, and more, except that until now it was not politically desirable apparently.
It's very windy here. On the mainland, especially in summer, it might be calmer for days or even weeks so you would need a lot of storage, but you probably can power the UK on wind if that's what you were determined to do, and when it's really blowing (much of the winter) you can export that cheap wind power too, offsetting the price of buying some of say Spain's solar power or France's nukes when the wind is calm.
Most of today so far for example grid wind was steadily about 13GW. Here on the mainland it seems pretty calm, but I guess out in the ocean it is plenty windy enough to turn those blades and make electricity.
