Hallo Sweetish Pea,
Sorry about the late answer, I just came upon this forum, but I hope it still may help.
We have olive trees growing outside, and they really are not as tender as people seem to think. Though I don't live in the UK, we can have temperatures of as low as -16 in winter, and lots of hard frost. The olives don't mind at all.
What they don't like is overwatering, and what they really don't like is feeding.
When we first bought our young trees, we dug a good deep hole for each, put some (home-made)compost in the bottom, and mixed it with some of the soil we had just dug out. Then we filled the hole with water, and planted the young tree.
We threw a couple of shovelfuls of sharp sand round the base of each, as a water-retaining mulch.
For the first year, we gave each tree maybe 20 ltrs of water a week during the summer (it was a dry summer), then the second year around 20 ltrs a fortnight.
None has been fed since, and they're all thriving.
Bear in mind they're trees which grow on rocky hillsides which won't support much else, and don't mollycoddle them. They shouldn't lose their leaves in winter.
We picked our first crop when the trees were three years old (not many certainly, but some) and now the oldest trees are seven, and we get lots of olives. Hope this helps, and good luck!
