Sheldon, what you've put pretty much does sound "jobs a good un".
At a guess from what you're saying, perhaps you didn't quite make the income threshold in the last 12 months to date, but with overtime you will break over that point, proven over a 12 month period very soon.
One way of making this requirement, is either a proven 6 months continuous earning, which translated over 12 months will meet the limit. Alternatively you can prove the requirement over 12 months salary (Say for example, you earnt 15k in the last 12 months, but then got a new job paying 40k, you wouldn't need to wait for 6 months to pass, because you would earn over the requirement in a month or two. You then just submit 12 months wageslips, including your latest 2 months worth at your new humongous salary - it will add up to well over 18,600k. No need for the P60 really, and of course, letter from your employer saying your yearly salary - as you must have that at the time of application.
Your kids will have British passports, so they aren't taken into account - it's only sponsored children who are taken into account.
Of course, this is just the salary requirement, you do then have the joy of proving the relationship with chat records, photos etc, but hey
