Communal Electrical Supply · UK public procurement notice

Communal Electrical Supplies

Scope of Works:

• The term ‘renew’ refers to the complete replacement of the existing system, due to condition or age. The work will include all new risers, laterals, landlord’s board and new wiring to feed communal electrical systems. It will also require coordination with UKPN on new meters and service heads as required.
• The term ‘upgrade’ refers to when existing installations are improved upon to meet the required standards and current regulations.
• The term ‘extend’ refers to where the communal wiring system needs to be extended to other areas of the building.
• The installation of the communal electrical supply is split into 3 parts of which all or any combination, may need to be renewed or upgraded.
• Intake Cupboard and associated electrical equipment
• Lateral Mains (including lift supplies)
• Risers
• The work will also include the replacing of switchgear, sub-mains cables, electrical equipment associated with the block’s landlord’s services as well as the emergency lighting within the intake cupboard.
• Where possible existing service runs are to be reused. Under certain circumstances, (e.g., where the existing riser has inadequate capacity, is not accessible or where asbestos removal is prohibitive), a new riser location will be necessary, and the works will then also involve the construction of the new riser cupboard.
• Works will include all necessary testing and certification, coordination with UKPN, and all

necessary fire stopping and associated builder’s works.

• Redundant cable is to be removed as far as reasonably practicable.
• The contractor may be required to facilitate smart meter fitting by others while the power is off.

Testing and Inspection of Landlord’s Supplies:

• On a 5-yearly basis the landlord’s supplies are to be tested and inspected in accordance with BS7671 and issued with a NICEIC EICR Certificate.
• Code 1 faults identified are to be actioned immediately. Where not possible, the system is to be shut down, made safe, and temporary supplies installed pending a full repair.
• Code 2 or 3 faults identified are to be brought to the attention of the client for instruction.
• The client will issue an annual list of those properties requiring the 5-yearly test and inspections. The detailed programming is to be organized by the Provider, including coordination with District Network Operator (i.e., UKPN) and Electrical Supplier (e.g., EDF)
• Residents should be notified generally about planned programmes when these are initiated. Within 5-10 days of the planned testing at a particular block, residents should get a further

detailed notice of the planned testing. This letter can be issued in collaboration with Hackney Council. It should clearly outline the impacts on residents and requirements of them.

• Orders for the above servicing regimes, and arising works required will be raised over the council’s Repairs IT system. This system will also be used for valuations and payments. All certificates are returned to the council via its dedicated compliance database. Training and access to these systems will be arranged on appointment.
• On completion of the works the LBH clerk of works will carry out a 10% inspection.
