external render quote - is this fair

[newclient]

I have the following quote on a part new build / part refurbishment - I was wondering if it was fair - outside London - Seaside town. Any help appreciated.

331 sq m2 external render - seaside town = 9.23 a sqm + 3.58 corners and beading + 10% main contractor price + VAT - scaffolding etc already in place.
