Statistical data set
Competent person self-certification schemes statistics
Data, updated every 6 months, on membership numbers of competent person schemes and the number of building jobs they have carried out.
Every 6 months we ask the schemes to provide us with information on their total registered membership at the end of the 6-month period and the number of jobs the registered members have undertaken in the period.
The latest published document sets out data for 1 October 2006 to 30 September 2016.

Registered membership is by business, not by individual. Many businesses will consist of more than one competent individual so the total number of competent individuals will be higher than the registered membership figures.
Schemes are authorised by the type of work that their registered members carry out. However, in many schemes, particularly those dealing with the installation of heating, hot water service, air-conditioning, mechanical ventilation and plumbing systems, registered members do more than one type of work. To prevent as far as possible double counting of registered members or notifications to local authorities (which often encompass more than one type of work) the statistics combine all types of work (except electrical installations) for each of the scheme operators.
Schemes have changed since the data first started being collected, so it is not always possible to make meaningful comparisons between past and current data.
