Quality Assurance

 

 

                                      

                                                                                       

 

  

 Quality of work is assured by
 
  • Use of computer software for SAP calculations that has been approved by the Building Research  Establishment (BRE) on behalf of the Department for Communities and Local Government

 

  • Membership of the National Home Energy Rating (NHER) quality management system that meets the requirements of BS EN ISO 9001:2000. Members are bound by the rules of the NHER scheme, have to pass a professional examination system, and have their work regularly audited

 

  • Membership of the NHER Accreditation Scheme for On Construction Domestic Energy Assessors.
    Members are bound by the rules of the scheme, must meet the required level of National Occupational Standards, have had their work audited for adherence to quality standards, must update their skills and knowledge regularly, and must carry current professional indemnity insurance of at least £1m.

 

  • The quality standard for Energy Performance certificates (EPCs), required by Government Legislation, is that 95% of EPCs are within +/- 4% of the true Dwelling Carbon Dioxide Emission Rate (DER) expressed in Kg C02 / m2 dwelling floor area / year. This true value is determined by the Accreditation Scheme's Compliance Team
