Acton Wells is single manned, 12hr roster, Grade 6. With Inner London allowance and booked Sundays, you're looking at £55K-£60K basic. Don't forget, we're no longer allowed to work more than 60 hours per rolling 7-day week, although some boxes and areas currently have derogations - so even if there is overtime available, you may not be able to 'grab' that much.
It's unusual for a single-manned box in that it has a VDU workstation. It can also get quite busy - e.g. this sample from yesterday:

There was a plan to introduce meal break relief at the busier boxes in this area - including Acton Wells - but I'm not sure if it actually materialised.
