United Kingdom

Original text. Later amendments are not shown.

  1. (a)

    From 26 September 2015 the seasonal space heating energy efficiency and useful efficiencies of heaters shall not fall below the following values:

    • Fuel boiler space heaters with rated heat output ≤ 70 kW and fuel boiler combination heaters with rated heat output ≤ 70 kW, with the exception of type B1 boilers with rated heat output ≤ 10 kW and type B1 combination boilers with rated heat output ≤ 30 kW:

      The seasonal space heating energy efficiency shall not fall below 86 %.

    • Type B1 boilers with rated heat output ≤ 10 kW and type B1 combination boilers with rated heat output ≤ 30 kW:

      The seasonal space heating energy efficiency shall not fall below 75 %.

    • Fuel boiler space heaters with rated heat output > 70 kW and ≤ 400 kW and fuel boiler combination heaters with rated heat output > 70 kW and ≤ 400 kW:

      The useful efficiency at 100 % of the rated heat output shall not fall below 86 %, and the useful efficiency at 30 % of the rated heat output shall not fall below 94 %.

    • Electric boiler space heaters and electric boiler combination heaters:

      The seasonal space heating energy efficiency shall not fall below 30 %.

    • Cogeneration space heaters:

      The seasonal space heating energy efficiency shall not fall below 86 %.

    • Heat pump space heaters and heat pump combination heaters, with the exception of low-temperature heat pumps:

      The seasonal space heating energy efficiency shall not fall below 100 %.

    • Low-temperature heat pumps:

      The seasonal space heating energy efficiency shall not fall below 115 %.

  2. (b)

    From 26 September 2017 the seasonal space heating energy efficiency of electric boiler space heaters, electric boiler combination heaters, cogeneration space heaters, heat pump space heaters and heat pump combination heaters shall not fall below the following values:

    • Electric boiler space heaters and electric boiler combination heaters:

      The seasonal space heating energy efficiency shall not fall below 36 %.

    • Cogeneration space heaters:

      The seasonal space heating energy efficiency shall not fall below 100 %.

    • Heat pump space heaters and heat pump combination heaters, with the exception of low-temperature heat pumps:

      The seasonal space heating energy efficiency shall not fall below 110 %.

    • Low-temperature heat pumps:

      The seasonal space heating energy efficiency shall not fall below 125 %.
