Is the figure £18,600 Gross or Net pay?

and also

If Im unable to earn £18,600 from one position, is it possible for me to obtain a 2nd position, part time work on the weekend and make it up to £18,600

This is my plan,
MOnday to Friday work full time earn about £15,000 per year (gross)

Sat and Sun - work part time earn about £5,000 - £6,000 pounds per year

Plus get my mum to put in a sponsorship too to make the application more stronger.


After my wife comes here with our two british kids my wife will work weekends and i can then look after the kids on the weekends.

What do you think ? is it possible?
