The latest technical standards apply to every new home registered with NHBC where foundations began on or after 1 January 2026, with tightened detailing at some of the most common failure points.
NHBC published the latest edition of its Technical Standards in January 2026, applying to every new home registered where the foundations were begun on or after 1 January 2026. The standards are reviewed annually, and this edition combines technical revisions with structural and editorial changes intended to reflect current practice and drive incremental improvements in build quality.
Several of the changes target areas that generate a disproportionate share of problems. Detailing at wall and roof abutments has been strengthened in Chapter 6.11. Requirements for roof underlays and associated risk assessments have been revised in Chapter 7.2. Garage floor structural requirements have been clarified in Chapter 10.1, and there is greater emphasis on sustainable drainage, with specific reference to CIRIA Report C753 for porous and permeable surfaces.
The context for all of it remains stubborn. Research continues to show the average new home has in excess of 140 defects recorded at completion, and a significant proportion of those occur in external areas and at junctions where one trade's work meets another's.
Standards raise the floor, but they do not install anything. What closes the gap between a standard and a finished home is the quality of the work on site and the willingness to get it right the first time rather than rely on the snagging list to catch it. That is as true of first fix and second fix carpentry as it is of any other finishing trade. It is the standard we work to on new build developments across Kent and the South East, including schemes for Shanley Homes at Sidcup, Redrow Homes at Maidstone and Abbey Homes at Gillingham.
140 defects per home is embarrassing, and most of it comes back to finishing. Standards going up every year is the right thing, but a standard does not hang a door. Somebody on site does. We do first and second fix that goes in right the first time, no snag lists and no callbacks. That is what you are actually paying for, and it is not complicated.
