Background Information

This is the eleventh industry survey of homebuyers carried out by NHBC, and covers the 12 months from October 2014 to September 2015.

The annual survey began in response to recommendations in the Barker Review of Housing Supply in 2004 and is a self-completion census of new home purchasers. Since its launch more than half a million survey returns have been received making it one of the most comprehensive continuous industry research exercises in the country. 

Of the 80,582 questionnaires sent, 45,342 were returned, a response rate of 56% – an outstanding response to a hybrid email and postal survey.

The statistical methodology used in the analysis of this survey has been approved by the Statistical Services Centre, University of Reading.

The methodology is principally the same as in the first survey, published in 2006, for which Ipsos MORI acted as a consultant. Industry results are weighted by builder to take account of the number of eligible homes they have built in the year. Individual company results are not weighted.

Company star rating results awarded by HBF are allocated according to the proportion responding ‘Yes’ to the question ‘Would you recommend your builder to a friend?’

5 Star Rating 90%+
4 Star Rating 80% – 89.9%
3 Star Rating 70% – 79.9%
2 Star Rating 60% – 69.9%
1 Star Rating 50% – 59.9%
