# The Electricity and Gas (Energy Company Obligation) Order 2022, Article 27: General requirements relating to heating measures


(1) A heating measure meets the requirements of this article if—
(a) the measure is not—
(i) the installation of equipment for the generation of heat wholly or partly from coal; or
(ii) the installation of a connection to a district heating system that delivers heat generated wholly or partly from coal;
(b) where the measure is the installation of equipment for the generation of heat wholly or partly from biofuel, oil or liquefied petroleum gas, the measure—
(i) is installed at off-gas premises;
(ii) is a repair of a central heating system; and
(iii) complies with the off-gas heating hierarchy in article 30;
(c) where the measure is the installation of a connection to a district heating system that delivers heat generated wholly or partly from biofuel, oil or liquefied petroleum gas, the measure—
(i) is installed at off-gas premises;
(ii) is a repair of the district heating connection; and
(iii) complies with the off-gas heating hierarchy in article 30;
(d) where the measure is the installation of equipment for the generation of heat wholly or partly from mains gas, or the installation of a connection to a district heating system that delivers heat generated wholly or partly from mains gas, the measure is installed at on-gas premises;
(e) where the measure is the installation of an electric storage heater, but is not a repair, the measure—
(i) has a responsiveness rating equal to, or greater than, 0.8 when assessed against the Standard Assessment Procedure; and
(ii) replaces an electric heating system at the premises or is installed at premises where one or more electric storage heaters are already installed;
(f) where the measure is the installation of an electric heating system, but is not a repair, the measure—
(i) has a responsiveness rating equal to, or greater than, 0.8 when assessed against the Standard Assessment Procedure; and
(ii) replaces an electric heating system at the premises or is installed at premises where one or more electric storage heaters are already installed;
(g) where the measure is the installation of a central heating system or a district heating connection not referred to in sub-paragraph (f), but is not a repair, the measure is an efficient heating system;
(h) where the measure is the installation of a boiler, but is not a repair—
(i) it is an efficient boiler; and
(ii) where the boiler forms part of a wet central heating system, hydraulic balancing of the central heating system is carried out following the installation of the boiler;
(i) where the measure includes the installation of equipment for the direct conversion of sunlight into electricity, the measure is installed at domestic premises—
(i) at which there is already installed—
(aa) a hydronic heat pump; or
(bb) an electric storage heater or an electric heating system that in either case has a responsiveness rating equal to, or greater than, 0.8 when assessed against the Standard Assessment Procedure; or
(ii) at which there is installed as part of the same ECO4 project as the measure—
(aa) a hydronic heat pump;
(bb) an electric storage heater, that meets the requirements of sub-paragraph (e)(i) and (ii); or
(cc) an electric heating system, that meets the requirements of sub-paragraph (f)(i) and (ii);
(j) where the measure is the installation of equipment for the generation of heat wholly or partly from biomass, the measure—
(i) is installed at premises which are in a rural area; and
(ii) generates heat from biomass which is wholly woodfuel; and
(k) where the measure is the replacement of an efficient boiler with another efficient boiler, the boiler being replaced is broken down and is not economically repairable.
(2) In paragraph (1)—
“hydraulic balancing” means the carrying out of steps to ensure the temperature difference is the same between the inlet and outlet of each radiator, or other heat emitter, in a heating system;
“mains gas” means a supply of the kind mentioned in section 5(1)(b) of the Gas Act 1986;
“woodfuel” has the same meaning as in paragraph 6 of Schedule 4A to the Renewable Heat Incentive Scheme Regulations 2018.
