BS 8499:2009 Specification for domestic gas meter boxes and meter bracket
As competition in the gas industry has increased, the introduction of new products has led to changes to certain designs of meter box for housing gas meters. Consequently, for some types of meter installations the market now comprises several distinct box designs.
The number of different designs is causing difficulties for gas installers, meter asset managers and other parties involved in meter installation. BS 8499 addresses some of the disparities in existing box designs to facilitate the installation of meters across the UK.
BS 8499 specifies requirements for gas meter boxes for use with single gas meter installations conforming to BS 6400, which:
a) Are supplied with gases of the 2nd and 3rd family, with a maximum capacity of 6 m3/h and a maximum operating pressure not exceeding 2 bar
b) Incorporate any of the following meters: diaphragm, ultrasonic, credit or prepayment.
It does not apply to multiple meter installations which are installed in the same housing.
BS 8499 covers the following designs of meter box, including any associated box extensions:
1) Built-in
2) Surface mounted
3) Semi-concealed
4) Universal.
Attention is drawn to the fact that the type and construction of a meter box is subject to approval by the gas transporter, and, without this approval, the gas transporter may refuse to connect or, in some cases, may disconnect the gas supply to the consumer’s premises.
BS 8499 also specifies requirements for the design of the standard meter bracket.
BS 8499 does not cover security shrouds intended to provide additional protection to meter installations.
Who will find BS 8499 useful?
- Gas meter box and meter bracket manufacturers

- Gas engineers and managers
