It doesn't matter to what any body else things of your educational year-you have taken (back) responsibility for the education of your children-you are in charge!
What you say goes!

The LA have no right to make any demands on anything you do-unless they have reason to believe an education is not taking place.....and you may have made changes to the way you educate them, but they will have been learning, even with sickness in your house-and definitely when you moved-think of all of the new events they will have encountered, all of them will be educational. Hell, life IS educational!
Our home based education did change dramatically-we were really quite structured at first, but that didn't work for us, so we became totally informal/autonomous home educators. We had NO timetable, No formal work, NO unnatural break between what is life and what is learning. We followed NO school terms, and definitely NO curriculum! We were very clear indeed in our written report to the LA, that we wouldn't have a visit, they wouldn't see the children, and that we didn't follow any sort of plan, and there was no formal work for them to see. The LA have always accepted this.
The vast majority of my home ed friends (and there are hundreds!) educate informally too. So you have nothing to worry about!!
Take a look at the Elective Home Education : Guidelines for LAs written in 2007 by the Department of Education, to tell LAs about home education
Especially look at section 3.13 which tells the LA what you don't have to do, and you'll see you are doing fine.
Section 3.13
Children normally attend school for between 22 and 25 hours a week for 38 weeks of the year, but this measurement of ?contact time? is not relevant to elective home education where there is often almost continuous one-to-one contact and education may take place outside normal ?school hours?. The type of educational activity can be varied and flexible. Home educating parents are NOT required to:
teach the National Curriculum
provide a broad and balanced education
have a timetable
have premises equipped to any particular standard
set hours during which education will take place
have any specific qualifications
make detailed plans in advance
observe school hours, days or terms
give formal lessons
mark work done by their child
formally assess progress or set development objectives
reproduce school type peer group socialisation
match school-based, age-specific standards.
so relax, have a drink
-you are doing fine!
oh and how will the LA know about you if you've moved house?
