English Language Schools in Herts (Potters Bar, Barnet, WGC)

[mumsareglam]

Can anyone recommend an English language school in the areas above?

I have an au-pair starting in mid September. She's going to stay for 6 months. Most of the courses at the local colleges, Barnet, Oaklands, Southgate are for 36 weeks.
I have seen one or two smaller ones but not sure how reputable they are.

Thank you
