Price by spec

What actually happens
- Power off in stages; circuits traced and planned
- Floorboards lifted and walls chased for new cables
- Every circuit rewired room by room
- New consumer unit (fuse board) installed
- Sockets, switches and lights fitted — second fix
- Tested, certified (EIC) and walls made good
Popular choices
Extra sockets while walls are openUSB sockets and outdoor powerWired smoke alarms (often required)
Regulations to know
- All of it is notifiable under Part P — use an NICEIC or NAPIT registered electrician who certifies their own work
- You'll receive an Electrical Installation Certificate; keep it for sale or remortgage
Tips from the trade
- Add every socket you might ever want now — it's pennies during, expensive after
- Plan it before plastering or decorating, never after
