In regulation 2 insert the following definitions in the appropriate places—

• ““environmental permit” means a permit issued in accordance with the provisions of the Environmental Permitting (England and Wales) Regulations 2010^f1 or the Pollution Prevention and Control (Scotland) Regulations 2012^f2;”

• ““heat loss calculation” means a calculation of heat lost which is carried out in accordance with the guidance issued by the Chartered Institute of Building Services Engineers and contained in CIBSE Guide C- reference data (2007 edition)^f3;”

• ““net heat input” means the means the rate of heat (expressed as the amount of heat over time) which is supplied to the plant by the fuel used, based on the net calorific value of that fuel;”

• ““NO_x” means oxides of nitrogen;”

• ““PM” means particulate matter;”

• ““properly insulated” means insulated so that the relevant maximum permissible heat losses set in BS 5422: 2009^f4 are not exceeded, where—

  1. (a)

     heat losses are calculated in accordance with the equations listed in and following the principles described in BS EN ISO 12241:2008^f5, and

  2. (b)

     pursuant to that standard such calculations include, in respect of underground piping, the insulating effect of the soil in which the pipe is buried;”

  1. (a)

     where the installation capacity of the smallest of the plants in the range is less than or equal to 500 kWth, the ratio of the installation capacity of the smallest plant to that of the largest plant in the type-testing range for which tests are carried out is no more than 1: 2, or

  2. (b)

     where the installation capacity of the smallest of the plants is greater than 500 kWth, then the difference in installation capacity between the smallest and largest of the plants within the type-testing range for which tests are carried out is no more than 500 kWth.”.
