Visitor Parking Plea

As the cruel hand of Fate would have things, our boiler has chosen the first day of winter to throw the towel in.

We've got a boiler man coming round on the 27th, which is fine, but as we live in the Gardens, he'll need a visitor permit to park - and we just gave our last one out to a man with a ladder and a hammer and an intention to fix our roof. I've ordered some more online, but I wouldn't expect them to be here by next Friday.

Would anyone possibly have a spare/excess/available visitor permit that they are prepared to part with? (Ideally, something that would cover the length of time it takes a pro to consider the merits of reviving an old boiler).  If you have and you would, it would be much appreciated.
