A dwelling should be maintained in a reasonable state of repair and will fail if:

One or more key building components are old and, because of their condition need replacing or major repair; or two or more other building components are old and, because of their condition need replacing or major repair. A building component can only fail to satisfy this criterion by being old and requiring replacing or repair.

Key building components are those which, if in poor condition, could have an immediate impact on the integrity of the building and cause further deterioration in other components. The list below contains some, but not all of those components. You will need to assess your property individually.

  • external walls;
  • roof structure and covering;
  • windows/doors;
  • chimneys;
  • central heating boilers;
  • gas fires;
  • storage heaters;
  • plumbing; and
  • electrics;
  • rain water goods.

This standard can affect the assessment of all HHSRS hazards under Part 1 of the Housing Act 2004.
