My place any weekend work is paid double time so double our daily wage rate.
Use to be time and half until I said hang on get clients to pay double time for fees and then we get paid double. Since clients where happy anyways since out of hours downtime still would cost far less than during office hours it was a win win.
three days work over xmas even just on call at £150 after tax is a bit low IMO.
