The National Association of Professional Inspectors and Testers, NAPIT, was formed in 1992 with the aim of enhancing the success and excellence of its membership through the promotion of professionalism, best business practices and leadership for the engineering and construction industry.

Scheme Background

Housing accounts for around 27% of the UK's carbon emissions. This major cause of climate change is a significant area of focus not only for environmental reasons but also because of the increasing costs of conventional energy supply.

Companies carrying out installation of microgeneration technologies must comply with the relevant Building Regulations. In addition, if installations are to attract funding under the Low Carbon Buildings Programme*, installers must be certificated under the Microgeneration Certification Scheme (MCS) which operates under the authority of the Department of Energy and Climate Change (DECC).

Since 2004, NAPIT have operated Competent Persons Scheme registers under licence to the Department of Communities and Local Government (CLG). These schemes allow self-certification against the Building Regulations for electrical installation, heating, plumbing and ventilation. This covers all of the Building Regulations applicable to Microgeneration work.

NAPIT are UKAS accredited under the MCS. By providing access to both grants and self-certification NAPIT will be providing a complete solution for the microgeneration installer in an efficient and cost effective manner.

*Note that grants must be applied for by the householder, for further information see www.lowcarbonbuildings.org.uk

Scope of the Scheme

Microgeneration is the application of renewable energy technologies on a scale small enough to apply to domestic properties, sometimes replacing conventional technology and sometimes supplementing it. The NAPIT Microgeneration Competent Persons Scheme aims to deliver approval both for Microgeneration Certification and for Building Regulations Self-Certification:

Microgeneration Technologies: Building Regulations Compliance:
  • Solar thermal hot water
  • Solar photovoltaic
  • Wind turbines
  • Heat pumps (ground and air source)
  • Biomass combustion
  • Electrical installation
  • Plumbing
  • Hot water storage
  • Heating system and controls
  • Solid fuel burning appliances
