Warning Signs That Indicate Rewiring is Needed
If your London home hasn’t been rewired since the 90s, it might be time to take a closer look. Homes older than 25-30 years often need rewiring to keep up with today’s safety standards. Let’s face it. Older wiring just wasn’t built for things like EV chargers or modern kitchen gadgets.
Here are some signs that show you need some rewiring or emergency electrical repair.
Flickering or Dimming LightsIf your lights keep flickering or dimming whenever you use appliances, it’s a sign your electrical system might be struggling to keep up with the power demands.

Tripping Circuit Breakers
Does your circuit breaker trip more often than it should? This could mean your system is overloaded or there’s a wiring issue that needs professional attention ASAP.

Damaged or Outdated SocketsCracked, scorched, or hot outlets aren’t just annoying. They’re a clear signal of electrical problems that need fixing right away to keep things safe.
Burning Smells
Notice an electrical burning smell around your electrical systems? Don’t ignore it. This is a serious red flag, and you should call a licensed electrician immediately.
Electric ShocksEven a small shock from a switch or appliance is a big deal. It’s likely caused by faulty wiring, and it’s something you’ll want an expert to check out right away.
Old-Style Wiring
Still have rubber, fabric, or lead wiring in your home? Or outdated cast iron switches? These are outdated and pose serious safety risks, so upgrading to modern wiring is a must.
For owned properties, electrical inspections should occur every 10 years. Landlords must arrange inspections every 5 years to comply with current regulations.
Process of Rewiring a House
Understanding the rewiring process can help you feel more prepared and know what to expect from your electrician.
First Fix: The Foundation Stage
This is where all the behind-the-scenes electrical work happens when rewiring a house before any plastering begins.
- Cable Installation
New electrical cables are run through your home, usually inside walls or under floors. This might mean accessing wall cavities or even lifting up some floorboards. - Back Box Installation
Back boxes are fitted for your switches and sockets. These act as secure base points for all your electrical accessories. - Circuit Planning
Power and lighting circuits are planned and installed to match both the latest regulations and your personal needs. - Consumer Unit Preparation
The location for your main consumer unit (fuse box) is set up at this stage, but the actual installation happens later during the second fix.
Second Fix: Wrapping Things Up
The second fix happens once the walls are plastered, and the property is ready for those final electrical touches:
- Switches and Sockets
This is where all the switches, sockets, and electrical accessories are fitted and hooked up to the new wiring system. - Lighting
Time to install the light fittings! Whether it’s standard lights, downlights, or smart lighting, everything gets connected and ready to go. - Consumer Unit
The new consumer unit is installed, and all the circuits are connected and tested to make sure everything’s running smoothly. - Final Checks
Comprehensive testing is done to confirm it all works perfectly and meets today’s safety standards. Plus, certification wraps it all up.
How Do I Prepare My House for Rewiring?
Getting ready for an electrician doesn’t have to be stressful, and a little prep can make the whole process smoother and faster. Here’s how you can help:
Plan AheadThink about what you’ll need like extra sockets, better lighting, or even smart home upgrades. If rewiring a house is going to disrupt your routine (especially in your main home), it might be worth considering temporary accommodation to keep things convenient during the renovation.
Clear the SpaceMove furniture away from walls, store valuables somewhere safe, and roll up or cover carpets where needed. Electricians will need clear paths to work, and rewiring a house can get dusty and involve lifting floorboards, so it’s best to prep multiple rooms in advance.
Make Access EasyEnsure your electrician can get to all the necessary areas, like lofts, basements, or locked rooms. Don’t forget to arrange nearby parking for their van and give them space to store tools and materials. This keeps everything running efficiently.
A little effort upfront can go a long way in making the process hassle-free!
Rewiring Costs for London Homes
Factors Influencing Cost
- Property Size and Layout
Bigger homes mean more wiring, more materials, and more time on the job, which naturally means higher costs. - Property Age and Construction
Got an older home? Rewiring a house can be trickier (and pricier) because solid walls and tight spaces take extra time and effort to work around. - Quality of Materials
If you’re going for high-end switches, sockets, and fittings, be ready to spend a little extra. The upside? They’re more durable, functional, and look way better. - Additional Features
Want smart home systems, fancy lighting, or extra circuits? These add-ons will expand the project and bump up the costs, but the results can be worth it!
Here’s a more detailed breakdown of the costs:
| Property Type | Cost Range | Notes |
|---|---|---|
| 1 Bed Flat Rewire Cost | £2,500 - £4,000 | Compact flats require fewer materials, but London labour rates increase costs. |
| 2 Bed Flat Rewire Cost | £3,500 - £5,500 | Larger flats need additional circuits and more comprehensive rewiring. |
| 3 Bed Rewire Cost | £4,500 - £7,500 | Three-bedroom properties require significantly more work. |
| 3 Bed Semi Detached Rewire Cost | £5,500 - £8,500 | Semi-detached houses often have more complex layouts requiring extra planning. |
| 3 Bedroom House Full Rewire Cost | £6,000 - £9,000 | Includes all circuits, lighting, and power systems. |
| Average Cost for Wiring a New House | £8,000 - £12,000 | New constructions allow easier access but require comprehensive systems. |
| Average Cost of Rewiring a 4 Bedroom House | £7,500 - £12,000 | Larger homes need extensive electrical work across multiple floors and rooms. |
Rewiring a house comes with a few extra costs to keep in mind.
If you need a temporary electrical supply, that’s an extra £200 to £500. Remember, all the work needs to follow the rules and meet the required standards!
How Long Does Rewiring a House Take?
This depends on a few things, like the size of the property, how complex the layout is, and whether you’re adding extras like smart home features. Having clear access and being well-prepared can help speed things up, but bigger homes or more extensive work will naturally take a bit longer.
| Property Size | Average Timeframe | Notes |
|---|---|---|
| 1 Bed Flat | 3-5 days | Compact properties can be rewired quickly. |
| 2 Bed Flat | 5-7 days | Additional rooms and circuits require more time. |
| 3 Bed House | 7-10 days | Larger houses need comprehensive rewiring across multiple circuits. |
| 4 Bed House | 10-14 days | Substantial properties require extensive electrical work. |
Note: These timeframes assume professional electricians working efficiently with good access and preparation.

Frequently Asked Questions
House rewiring, how often should I do it?If you’re in London, most homes need rewiring every 25-30 years. That said, older homes or ones with constant electrical issues might need it sooner. Regular electrical inspections can help you figure out if it’s time for an upgrade.
How do I know if my house needs rewiring?Look out for flickering lights, tripped fuses, old-fashioned sockets, or exposed wiring. If it’s been decades since your home was inspected or you’re not sure about its current condition, it’s a good idea to get an Electrical Installation Condition Report (EICR) done.
Do I need to move out when rewiring a house?Rewiring can be messy. Think lifted floorboards and replastered walls. For big jobs, moving out is usually recommended, especially if you’ve got a family. However, it really depends on your home’s size and your patience for living in the middle of a project.
Do I need a permit to rewire my house in London?Yes, rewiring is considered “notifiable work” under UK Building Regulations. You’ll need a certified electrician who can handle notifying your local council or provide the necessary compliance certificates.
Can I rewire my house myself?Rewiring isn’t a DIY job. All electrical work in London has to meet Building Regulations, and only certified electricians can issue safety certificates. Messing it up can be dangerous and might even void your insurance. Best to leave it to the pros!
