Good Evening to All, 
It's so nice to have you all to ask advice from, because I am still learning as I go with HE, this place is invaluable !
@ Tabilope, having lurked here for ages and read others experiences, I think that maybe I have been far too rigid regarding the NC, and that this year maybe I can relax a bit, and make my life a little easier in the process. I understand how your DS feels when you mention certain history or science projects, because I have had the same reaction from mine !
You must be one of the lucky ones with regards to the LEA, I have had my own personal experience with mine, which hasn't been too bad (more below) but some stories I have heard have been toe-curling !
@ greenbananas, Hi many thanks for your advice regarding the books. I went to the bookshop called "The Works" (don't know if you know it ?) and bought her loads of the books where they are "4 for £5". We have the set of "Little Bear" stories, and lots like "Owl Babies"...I just tried to choose books that I thought would interest her, but that weren't too long to become too "trying" for her. She has been reading those sorts of books on her own for the past year, but it was partly because of an LEA visit I had when the woman asked how did I know her reading had improved (well, actually because I taught her to read !) and what did I think her reading age/ability was. I just thought perhaps I should get a set of "recognised" reading books so that I would be able to say next time, "well she's reading Level X with ORT" (or Ginn) mainly to reassure the LEA. I have heard good and bad about the ORT because of the reasons you describe and just wondered if it would be worth spending lots of money, or not ! I might just invest in a couple, and see if she likes them first !
@ Saracen,
Hi ! We have had 3 visits from our LEA. Our first visit was from the EWO, which was to find out why we had de-registered the children, and we shocked her with the reasons we gave, and it went very well ! We then had a visit from the Education Officer, who was supposed to offer us advice about the best books/texts/resources we could use, which was fruitless as we had already done our own research and had everything and more that she advised ! We also had to give her our outline for how we intended to educate the children, and then a couple of weeks later we received a lovely letter from her saying that she was more than happy with our proposals and that she looked forward to seeing us in a years time.
This year, for our 3rd visit we had a letter requesting that a new lady come, as the other one had retired, which was fine. The visit went very well, and the children stunned her with how they spoke to her and conversations they had together, plus examples of their work. (It was a little bizarre, as she chatted to my DS about space and black holes among other things and when she asked DS a question he couldn't answer about black holes, off he went to get his space book and came back to read her a paragraph containing the answer !) She seemed to be in awe of him then and told us that we clearly had 2 very intelligent children who were working above their respective ages. She was very enthusiastic but just said to continue as we were. She also said that she was setting up a group for HE in our area and that she would email me the details. Well, she went away and a month later I rang the dept. to ask why we hadn't had a letter from her. The following day we had a very rushed letter, and it was as if she had no idea who we or the children were, and to date I still haven't had a email regarding the group ! When she left us she mentioned also that she would see us in a years time, but in the letter it says that she wants to visit in 6 months time ?!
Now, I don't feel that she needs to visit in 6 months, as they offer very little help anyway, but I wasn't aware that I could refuse to let them visit, or send them updates, until you mentioned it. I didn't see any harm in letting them visit, if only to "prove" that the children are not being mistreated in any way. Before our first visit I did recieve some advice from other HE'rs saying "don't let them in, don't let them see the children, they are a nightmare", but as we have nothing to hide, I didn't see them harm. I did hear some awful stories about how other families are treated, and it scared me silly. 
I suppose what I am getting at is, can I contact them and say that I no longer wish to have visits, as they have nothing worthwhile to offer ? (Maybe not quite in that way ?!) I am actually annoyed that some LEA's can be very intimidating, and others lax, in the sense that ours really did have nothing to offer us with regards to HE apart from to say "teach what you want, how you want". I think what hurt me more than angered me was that she gave me a sheaf of leaflets with websites on, (most of which I had discovered myself, and the rest were defunct), but also a leaflet for an internet school she said was for HE children where she said they could choose to take part in lessons via webcam, which was fine, until I looked up the school and the main message is "for challenging children who cannot or will not attend mainstream school" 
Oh, see, I'm rambling again now....but I hope you understand what I am trying to say/ask ?! Can I just refuse any more contact with them ? What has been the response from yours when you declined to send updates ?
(I like to think I am a little bit militant myself too !)
Take care,
