Observation:
The inspected apartment contains two consumer units. We were instructed to carry out an EICR on the storage heater board, which is fed via a separate Economy 7 meter located in a communal cupboard on the ground floor. Our inspection found that all Economy 7 supplies in the building are fed from this meter and individually protected via double pole switch fuses containing 50A BS 1361 fuses.
The outgoing cable from each switch fuse is standard PVC twin and earth, which ascends the wall with no mechanical protection as far as could be determined. Within the apartment (first floor), the storage heater consumer unit is fixed to a plasterboard wall. There is a large, unsealed hole behind the unit where the cable enters, and again, no mechanical protection is provided.
The installation is wired in old (pre-2004) colour codes, with no evidence of prior inspection or testing. Based on condition and materials, the installation appears to be approximately 30 years old.
The client has informed us that the landlord or building owner has been made aware of our findings but has expressed frustration regarding the observations.
Classification:
C3 – Improvement Recommended
Regulation Reference:
BS 7671:2018+A2:2022 Regulation 522.6.202 – Cables concealed in a wall or partition at a depth of less than 50 mm from the surface must be provided with additional protection by an RCD not exceeding 30 mA or enclosed in earthed conduit/trunking or protected against penetration.
