"My LEA isn't good or bad, it's just (to the dc) a boring appointment we have once a year, they don't offer any help or support, pointless from our point of view."
Has your LA ever told you that these visits are optional? If not, if they have misled you into believing you're required to have them, then that's very irresponsible of them. Perhaps it isn't true that the LA is neither good nor bad! If you aren't getting any benefit from the annual contact with your current LA, you don't have to continue to go along with it. I imagine you can think of better ways to use your time than having boring pointless visits. You could write and tell them that you don't wish to have any further visits.
In the absence of any evidence to suggest that you aren't educating your children properly, it's arguable whether the LA ever has the right to receive any information from you whatsoever. Most HE families do choose to provide information as a one-off at least. The law is somewhat unclear on whether this is essential.
But the law is very clear that if the LA does not have any reasonable grounds for concern about your educational provision, there is no need for them to continue to take any interest in your children's education once you have provided them with the information in the first place. You've done that in the first visit you had, so (assuming they've never said your provision was unsatisfactory, or raised any serious issues) now you have definitely met any obligations you may have had.
Many LAs try to claim that they need annual contact with all HE families, but there is no legal basis for this. You could ask your LA on what basis they want to monitor you, and quote to them from the 2007 "Elective Home Education Guidance for Local Authorities" from DCSF. This is legally binding on LAs. "2.7 Local authorities have no statutory duties in relation to monitoring the quality of home education on a routine basis."
