"When the UK currency recovers"?
You mean IF it recovers. It would probably fall lower if there wasn't a fair amount of doubt whether Brexit will even happen. If they follow through and serve Article 51 notice, I expect the pound will drop another few percent. If they announce there will be a vote of Parliament over serving the notice, then it will jump up, especially if the vote fails as one would expect.
Then you get to deal with the mess from Brexiters who weren't aware last month's vote was not a binding referendum, but at least the pound would be back to where it was before (and you can see how long before HP, Lenovo etc. drop prices back)
