A domestic rewire is one of the most important electrical upgrades you can make to your home—but it’s also one of the most misunderstood. Whether you’re renovating an older property, experiencing frequent electrical issues, or just want to future-proof your home, a full rewire could be essential for both safety and performance.
In this guide, we’ll break down what a domestic rewire involves, when it’s needed, and how Helpi makes it easier for homeowners to find qualified electricians—with no hidden costs for the tradespeople we call Helpi Heroes.
A domestic rewire involves replacing all of the electrical wiring in your home. This includes not just the wires, but also:
-
Sockets and switches
-
Light fittings and circuits
-
The consumer unit (fuse box)
-
Earth bonding to water and gas pipes
The goal is to bring your electrical system up to current UK safety standards, ensuring it can safely handle modern demands—like home offices, electric ovens, and smart tech.
You may need a full or partial rewire if:
-
Your home was last wired over 25–30 years ago
-
You’re seeing blown fuses, flickering lights, or tripping breakers
-
You’re renovating or adding new circuits
-
The wiring is old and unsafe (e.g., rubber or fabric-insulated)
-
There’s no RCD protection in your fuse box
Older homes often weren’t designed for today’s electrical load, and that can pose serious fire risks if left unaddressed.
A rewire is a major job and can take anywhere from 4 to 10 days, depending on the size of the property. It involves:
-
Lifting floors and chasing into walls
-
Installing new cables, sockets, and lights
-
Replacing or upgrading the consumer unit
-
Full safety testing and certification
It’s often best done before decorating or during a major renovation to minimise disruption.
Costs vary depending on property size, but on average:
-
1-bed flat: £2,500 – £3,500
-
3-bed house: £4,000 – £6,500
-
Larger homes: £7,000+
Always get a fixed quote, check that the electrician is Part P certified, and confirm that they’ll provide an EIC (Electrical Installation Certificate) upon completion.
