One of the most important things you can do, for you and your family, and as a homeowner or landlord, is to ensure your home’s wiring is well maintained. Full or partial house rewiring probably isn’t something you have on your home improvement wish-list, but safety must always come first.
Your home and its electrical wiring should be safe, compliant, and future-proof.
The risks of ignoring the state of your wiring are significant, with potential hazards including fire or electrocution, which can both be fatal. Aside from the perks and peace of mind of knowing your family is safe, house rewiring will increase your property’s value and saleability, particularly if it has a few years on it.
When Do You Need Electrical Rewiring?
You may need house rewiring if your home and wires are old, faulty, or need alterations or additions.
Old or faulty: House rewiring is often needed for homes that are 25 years of age or older. The work carried out by a qualified electrician will bring the wiring up to standards and reach the level dictated in building regulation.
Alterations or additions: Wiring that does not meet standards is often uncovered when you add a circuit or wiring to your existing system or when you add an extension to your home. If you make home improvements, such as an attic conversion or adding a garage, then house rewiring may be required under building regulations. An electrician will test existing wiring to ensure it is rated for any new electrical load.
The tell-tale signs that you might need a full or partial electrical rewire include:
- Old style fuse box
- A mix of light switches and plug sockets
- Fuses keep blowing
- Lights flicker
- Plugs and sockets are discoloured
- Burning smells
- Buzzing or crackling sounds
- Fabric, lead, or rubber insulated wire
How Do You Rewire A House?
Rewiring of a house begins with a full assessment and EICR safety test. The rewiring work may include replacing wires, installing a new fuse box (consumer unit), fitting new back boxes for switches and sockets, adding new sockets if required or desired, and bring earthing up to current requirements.
Existing wiring will run under your floors and through your walls. This means that floorboards may need to be lifted, and walls may need to be drilled into.
Stage one of rewiring includes laying the initial wiring and back boxes. Stage two includes adding the light fittings, switches, and sockets, with wiring connected to the new consumer unit.
If a renovation or extension is underway, initial wiring (first fix) is installed before plasterboarding and decorating, typically at the same time as plumbing.
In all cases, the cost to rewire a house will be discussed before rewiring begins.
