I'm with rosielou here. Very similar case to my own (am a namechanger) - refusal to assess, pts 2 3 4 appeals, plus costs of reports and witnesses for SALT, OT, psych, EP, EP school visits, travel costs, even the initial diagnosis had to be paid for as NHS refused at first. The school we got is a residential AS school (so very expensive, more than the cost of Centre Academy in this case), and pretty much all the parents of dc there have had to spend the same. It's not fair, but weighing up the cost we spent vs. the cost of provision DS gets (over the 8 years he will spend there) makes me feel that it was at least 'good value'. And while our solicitor was expensive, she was good and worked hard on our case, so I don't begrudge it at all.
I am a single mum and get tax credits, housing benefit etc - really struggled to pay those legal fees. But I think it was the right thing to do for DS and I felt empowered by having an advocate, rather than being exploited. It would have been much worse to not have access to them at all and be forced to represent myself, or depend on charity advocacy services (I initially used those but they expected parents to take on more than I could manage, whereas the solicitor did far more letter writing and chasing up for me, which I needed at the time).
