Welcome to my forum.
Your ratings echo the HBF customer Satisfaction Survey and NHBC Quality Awards (2016) won by their site managers and my own thoughts. Despite Barratt's five star rating and 70 NHBC Awards, they are only better because they try to fix their defective homes after people move in. The same cannot be said for other house builders.
The photos below, were taken by a Barratt buyer who moved in to their "finished" new home on 30 June 2016, Barratt
financial year-end date. Clearly this house is far from finished or to an acceptable standard.
Persimmon (aka Charles Church) 3 Star rated - 7 NHBC Awards
Taylor Wimpey 4 star rated - 57 NHBC Awards
Barratt (aka David Wilson) 5 Star rated - 79 NHBC Awards.
The quickest way to ruin your CV is to work for a house builder.
You will never get an opportunity to go back into contracting/construction ever again, such is this industry's bad reputation!
