Just a thought, but may be worth checking if a Cosham/Chichester season for the appropriate duration will save you any money. Given the big discount on seasons it's possible that it will.
NRES▸ season ticket calculatorThanks for the link. However in July & August, I can use my railcard before 10am without any minimum fares (so day tickets work out cheaper).
Also, its an agency job with no notice period in the contract. I've had experience with another agency before where they didn't need a whole bunch of temps (myself included) half way through a day and just sent us all home (to make things worse, we only got paid for the three hours we'd been there that day). So I'm being more restrained this time by only buying day tickets - even if they work out more expensive.
Ok, I have a railcard and even in July/August (ahem - this assumes the guards actually remember the minimum price rule in the other 10 months which most don't) if doing the journey every day, a season is cheaper
As a contractor I also have the insecurity part but you cam claim back the difference between the daily fares and the season if you end up out of work mid ticket
You can certainly do it for monthlies so it is worth considering if you can get the initial funds for the monthly
