Chimney Notice Plates

This is still a subject that attracts many questions as to when a plate should be provided. Approved Document J gives the following clear guidance on how to comply with the following mandatory Requirement J4 of the Building Regulations for England and Wales.

" Where a hearth, fireplace, flue or chimney is provided or extended, a durable notice containing information on the performance capabilities of the hearth, fireplace, flue or chimney shall be affixed in a suitable place in the building for the purpose of enabling combustion appliances to be safely installed. "

(Similar requirements for provision of a notice plate apply in Scotland as referred to in F3.12 of the Building Standards (Scotland) Regulations, which also requires a plate when an appliance is fitted).

The installer is considered to be the person responsible for providing the completed notice plate and fixing it in accordance with the requirements given in the following clauses 1.56 to 1.58 of the Approved Dcoument J.

1.56 Where a hearth, fireplace (including a flue box), flue or chimney is provided or extended (including cases where a flue is provided as part of the refurbishment work), information essential to the correct application and use of these facilities should be permanently posted in the building. A way of meeting this requirement would be to provide a notice plate as shown in Diagram 16 {the Topstak Chimney notice plate shown below is similar to the one in Diagram 16} conveying the following information:

  1. The location of the hearth, fireplace (or flue box) or the location of the beginning of the flue;
  2. The category of the flue and generic types of appliances that can be safely accommodated;
  3. The type and size of the flue (or its liner if it has been relined) and the manufacturer's name;
  4. The installation date.

1.57 Notice plates should be robust, indelibly marked and securely fixed in an unobtrusive but obvious position within the building such as:

  1. Next to the electricity consumer unit; or
  2. Next to the chimney or hearth described; or
  3. Next to the water supply stop-cock.

1.58 For chimney products whose performance characteristics have been assessed in accordance with a European Standard (EN) and which are supplied or marked with a designation as described in Paragraph 0.4 (9), the installer may optionally include this designation on the label as shown in Diagram 1.9.
