You don't actually need a written contact. As long as everything is of a reasonable amount.
I'm only doing it just to be an arse.
But if you go to citizens advice or their website it's all laid out under cancelling building or decorating work.
We have rights as well.
The thing I've got is the woman booked everything by text.
It also states if their was a face to face site visit you lose the right to any cooling off period as you would get by just pricing over phone.
A mate of mine was in the same situation before he emigrated 12 months ago.
Which he did the same to be a c**t.
He even went small claims for the £25 it cost him to initiate it.
He actually won and the woman had to pay I think it was about £300 in the end all for a letter he sent asking for £50 cancellation fee.
I don't expect anything to come from it and if it hadn't left me in the lurch I wouldn't have even been pissed but it got my goat and though right I'm gonna be a c**t
