Trade talks


One hour


We've updated our very popular Trade Talks to reflect current construction methods. These one hour talks, delivered by NHBC building inspectors, are designed to highlight to trades/site operatives the most common reportable items or defects that the inspectors and claims investigators encounter on residential developments and give practical guidance on how to prevent these problems occuring. They can be delivered on or near your site, provided that a suitable room is available to seat the attendees, such as a large site office, canteen, nearly completed property, show house or another venue close to the site.

Suitable for:

Carpenters, bricklayers or ground workers (trades/site operatives).
