To ask the Secretary of State for Business, Energy and Industrial Strategy, pursuant to the Answer of 1 May 2019 to Question 245593 on Boilers: Natural Gas, what proportion of boilers sold after the introduction of the current standards met or exceeded the minimum energy efficiency standard of 92 per cent.

To ask the Secretary of State for Business, Energy and Industrial Strategy, pursuant to the Answer of 24 May 2019 to Question 225264 on Boilers: Natural gas, if he will indicate where the research carried out on real-world performance of boilers is to be found on the www.brgroup.com website.

To ask the Secretary of State for Business, Energy and Industrial Strategy, pursuant to the Answer of 24 May 2019 to Question 255264, in what way (a) the nature of buildings and (b) the use of a product by the consumer affects the efficiency of the boiler.

To ask the Secretary of State for Business, Energy and Industrial Strategy, pursuant to the Answer of 24 May 2019 to Question 255265 on Boilers: Natural Gas and with reference to page 27 paragraph 3.1.13.2 of BSI Standards Publication BS EN 15502-1:2012+A1:2015, whether boiler efficiency must be measured in situ rather than under test conditions.

The 2018 uplifts to boiler installation standards were made through an amendment to the 2018 Building Regulations. Compliance with Building Regulations is enforced by Building Control.

Compliance with Energy-related Products (ErP) standards is carried out by Notified Bodies, as defined by EU Directive 92/42/EEC: Hot Water Boilers. A list of Notifying Bodies can be found at the following URL: http://ec.europa.eu/growth/tools-databases/nando/index.cfm?fuseaction=directive.print&refe_cd=92%2F42%2FEEC

In response to his question on the percentage of boilers sold after the introduction of the current standards, I refer the hon. Member to the answer I gave him on 24th May 2019 to Question 255264.

The details of the research carried out on real-world boiler performance are available here:

Boilers operate within a household heating system comprising pumps, pipes, emitters and controls. The efficient operation of the system depends on the proper sizing, positioning and maintenance of these components to ensure how water is distributed as it should around the building. The heating system has a dynamic relationship with the fabric of the building such that efficiency is also affected by the level of insulation, ventilation, the extent to which doors and windows are kept open, and ambient heat from other household systems. Performance is also affected by the manner in which the consumer makes use of timers, thermostats and individual radiator controls, and by variation in gas content.

Boiler efficiency must be measured under test conditions to ensure comparability between products. There are too many variables in situ, as described above, to allow fair comparability.
