Gap measures roughly 50cm x 70cm. I've just been quoted £375 by a trader to source a gate and fit it. I've just looked online and the gate photo he sent me comes to £138 including gate post. So that over £200 for the fitting!! Is that normal? I feel like he's conning me. FWIW, I've left so many messages for fencing people to call me back but they never do. Also, we're in NE London so not sure if these prices are normal.
