This is a case of that irritating phrase - manage your expectations. You would be extremely, extremely lucky to see them anywhere in the UK. It depends on the solar weather activity to start with. The graphs here

show that solar activity is about to increase in the next couple of years, and this year is an unlikely one. Then, British astronomy is prone to our weather interfering as well. On several occasions in the past I've heard the possibility mentioned on the weather forecast, when there was unbroken cloud. On the one occasion I have seen them, they were faint orangy columns mingling with sodium street lights across the river in Essex. Still not convinced by them.
OTOH, I was phoned once from an astronomy society in Kenley, Surrey, which was seeing them, but though I was at the same latitude in Gloucestershire, by the time I got to a clear horizon, they were gone.
Solar weather, like ours, is variable and not very predictable. There can be big events, coronal mass ejections, which are completely unpredictable. I once came out in a rash by sunbathing during one which no-one knew about while it hit us, and which subsequently got NASA very worried about the effects on astronauts. They would cause dranatic displays, but you'd need to organise a trip in just a few minutes.
After all the negative stuff, however, I have seen them, properly, twice. Once on a cruise to see a solar eclipse, plus aurora, and once on a specialist astronomy cruise beyond the North Cape. On the first we had two land based trips north of the Arctic circle, one of which was in a useless place with street lights, the other was better, and we had a professional photographer for advice.
The second was on a Hurtigruten astronomy cruise, advertised as offering a free trip if the aurora doesn't show. We had a splendid show, and the astronomer said it was the best he had seen, over the whole sky. (That didn't stop a woman complaining in the breakfast queues that it wasn't good enough. She thought it would be like the speeded up photoshopped stuff on TV. It isn't.) It had been a particularly good bit of solar weather - the photographer from the eclipse trip was on a "see the aurora" flight that night, and a friend of ours was in Alaska, and both thought it particularly impressive.
There is no way to predict nights like that.
And in Iceland, I saw nothing.

You need, I am afraid, to save up and then to get someone to look after the dogs.
