Thank you for all your feedback.
In response to questions...
I do know the family extremely well. Have always been supportive of their choice to home educate up to now. Have swapped tips with parents too in past on what seem to have and have not work in helping to stimulate children with learning.
They have children of various ages, but am only now concern as they appear to be putting in less input into doing stuff with the children, and more doing their own thing, but without the children if that makes sense, so it not a case of them learning whilst doing stuff out in the community, because they're not actually getting out there with parents.
I was thinking if they got child assessed, they might get more money to support child in education, as I was under impression home ed can access some funding to assist with education of children, but maybe I got that wrong?
I have no concerns whatsoever about their welfare, so don't feel that it warrants involvement of Social Services.
A number of people are under impression that if you home educate, the LEA does check up regularly, but this is not the case. I know this particular family have had only 2 visits in the last 12 years or so, and the LEA don't even get to see the child when they visit if parents don't want them to.
I think the reason why parents won't discuss the issues, is because they are in denial that anything is wrong. They often play their cards close to their chest about a number of things, and it can take years for them to admit that actually there was something wrong or that they did need support. And at the same time they are deeply suspious of everyone or gets cross that no one offered support at time, as though we were all suppose to be mind readers!
I think I will contact ed welfare just to query, as I don't want to be in the position a few years down the line where the children turn round later and say "Well if you were concerned, why didn't you do something?" and not have an answer for that.
I know that some will disagree with my decision, but my gut instinct telling me that something not right at moment and that the parents need support in addressing the needs of their children. I understand that it is the parents' choice to home educate, but what rights do the children have, if their needs are not being met? Particularly in this current climate where every advantage you can get, will (hopefully) help you in the long run.
