Hi Tootingtwins, I know a couple of lovely tutors nearby. I'm not sure if they're 8+ specialists but they definitely have 11+ experience and are great with kids.
Emma lives near Dulwich College and is full of energy and enthusiasm. She mainly tutors primary and 11+, across a huge range of subjects, working in schools and with families. She also does a lot of Shakespeare and drama workshops in schools and can work wonders with a child's confidence. You can read all about her, watch a short video on her and email her directly here:

Mary would be another option, she lives in Streatham and does a lot of English, admissions and 11+ tutoring. She's completely lovely, relaxed and friendly (I think it's the yoga) - more about her here:

William has lots of experience and is a lower cost option as well (£32/hr), he's tutored for years, is a sweet guy and does a lot of tutoring in inner-city schools with Tutorfair's charity program:

Please click the links and contact them directly, or let me know if you'd like some more options. Tutorfair is a cashless system where you book them via the website as well (which keeps the commissions low) and there's a 5% optional donation which goes towards the charity side.
I hope that helps!
