What this price does not include
- Upgrading the existing cabling if circuits are found to be faulty or undersized during the change-over — quoted separately.
- Three-phase, busbar, or commercial distribution boards — this calculator covers domestic single-phase boards only.
- Multiple boards in one property priced from a visit only (the online tool handles one board at a time).
- Structural access works if the board is in a challenging location (buried, in a sealed cupboard, or difficult to reach).
- Parking costs in permit zones — a permit or bay suspension is the customer’s responsibility.
Not for three-phase, busbar, or big commercial plant — survey for those. Domestic calculator only.
