Alan Pither

Assessor and Online Mentor

Alan Pither has been professionally involved in energy efficiency assessment and advice since 1985, running a small company based in Shropshire since 2002. Alan Pither Ltd is an ABBE and City & Guilds approved centre for all of the energy assessor qualifications and regularly delivers training courses for BRE and NHER. He also leads the Energy Advice Training Consortium which has developed a range of courses for energy advisors at different levels. In addition to training he offers a range of consultancy services to local authorities, housing associations and individual building owners. These include the development of energy efficiency and climate change strategies as well as building surveys and recommendations for energy efficiency improvement measures. The latter cover all types of building but the majority are large domestic properties that are being refurbished and/or extended, usually off the mains gas grid so advice on alternative heating options is also needed.
