House Rewire Cost in London – Prices & What to Expect (2026)

This guide will tell you about house rewire costs in London, what additional costs you need to think about and how MyJobQuote can help you to find a trusted electrician.

Average Cost of a House Rewire in London

A house rewire cost in London is on average around £3,000 to £11,000 with labour and materials. Additional work or complex jobs that extend labour timeframes will also increase the total cost.

There are many older homes still lingering in London. Some were built as grand places in the Georgian, Victorian, and Edwardian eras and have since been converted into flats.

You also see a lot of Victorian and Edwardian terrace houses around the place. In the 60s and 70s, purpose-built tower blocks were built to replace areas destroyed during the war.

Old wiring that doesn't meet modern safety rules can be a real danger - you put the systems in to stop you getting electric shocks and power overloads, but they're not there in older systems. It's not just the shock risk; the whole system might not even be up to scratch anymore.

Getting someone to come and have a look at your wiring before you even start rewiring is very important for figuring out how old it looks and what condition it's in. Doing a full rewire will bring you up to the latest safety standards, and you can then go buy all the new energy-saving appliances you want.

Modern wiring is designed to handle all the gadgets we use today without causing any problems. Before work starts, it's well worth getting an electrical survey to understand what's going on with your wiring.

This will give you a good idea of what the place is like and guide your rewire.

London House Rewiring Prices (Full rewire):

The cost of rewiring a house in London depends on the property type and size, and whether you have a full or partial rewire.

A full house rewire in London covers the whole of your home. A partial rewire means you only have a certain area or areas rewired. For example, if you have a loft conversion or rewire a bathroom to add an electric shower or sauna.

A partial rewire is a cheaper option. You can expect to pay between £800 and £1,200 for the electrics in a loft conversion. An electrician in London will, on average, charge between £40 and £75 per hour.

For a standard three-bedroom house, the average cost of rewiring can be anywhere between £4,500 and £8,000 - although that's going to depend on some factors such as the specifics of your property and just how complicated a job it is.

If you want a more realistic idea of how much it'll actually cost to rewire your home, then a house rewiring cost calculator is a good place to start - it will be able to give you a more accurate estimate based on the specifics of your home and any other bits you might need done.

Factors Affecting the Cost of a House Rewire

Common factors that influence the price of a house rewiring job in London include plastering or painting after the rewiring is completed.

Additional work will also have a bearing on the cost, should you decide to have extra work carried out, such as the installation of smart switches or an EV charging station in the garage. Costs are also affected by:

• Size of property – Larger properties will be more expensive
• The age of the property – Older properties might be more complex
• Empty or Occupied – An empty property is quicker and easier to rewire, which will mean lower labour costs
• Ease of access – Access issues can add to labour timescales, which will mean a higher quote
• New consumer unit , which will cost on average, between £500 and £70,0 although for a full rewire, it may be included in your quote, so check each quote you get for this.
• Level of finish – Painting and decorating, replastering and making good
• Material Costs – The type of wiring, sockets, switches, and other bits you choose can potentially blow your budget
• Flooring Replacement - If you have to get the floor up during the rewiring process, you may need to factor in a replacement floor as an extra expense
• Higher Labour Costs - Breaking a rewire into a series of stages can end up costing you more in labour because you're looking at repeated visits and extra charges piled on top
• Regional Fluctuations in Costs - Labour and materials tend to be pricier in the South East, especially London, compared to other areas

Full Vs Partial House Rewire Costs

While a partial rewire is cheaper, it does not cover all the electrics in your home. If you want to be up to date with current regulations and safety rules, then a full rewire is your best option. Not only will it enable you to install modern appliances safely, but it will also make your home more appealing to buyers if you put your home up for sale.

The average cost of a full rewire in a typical London 2-bedroom terraced house will cost between £3,500 and £5,500. Partial rewires depend on the work you are having done, but on average start at around £1,000. Prices in London are typically higher than in other parts of the UK, so you can expect to pay more for the services of an electrician compared to places like Birmingham or Glasgow.

Additional Costs to Consider

More often than not, there are additional costs which sometimes get overlooked.

When you’re budgeting for a house rewire, you should also take these common costs into consideration:

• New sockets and switches – You can either buy standard budget designs at under £5, or you can choose premium styles which can cost from £20 to over £100
• Smart home features – smart lighting for an entire home costs between £3,200 and £10,500, depending on the size of your home
• Electrical certificates – If you want an EICR certificate , you should expect to pay between £100 and £300 for a London property
• Plastering and redecorating - plasterers and decorators often charge by the hour. A plasterer in London will cost between £30 and £40 an hour, while a painter and decorator’s hourly rate is between £23 and £35 an hour.
• Upgrading fuse boards (consumer unit) – between £450- £550 – Sometimes this is included in a rewiring quote. Check to make sure.
• Parking permits or access issues in London streets – Each London borough has its own rules and regulations about parking. Parking permits for tradespeople are available, and costs range from £45 to around £66 depending on the area and the duration of the permit. Tradespeople may add the cost of parking and travel to your quote

How Long Does a House Rewire Take?

Signs Your Home May Need Rewiring

• Your electricity often trips
• The circuits and sockets in your home aren’t earthed
• Buzzing noises are coming from the sockets
• Your lights often flicker
• Scorch marks appear on sockets, which may be warm to the touch
• Old cables with rubber or fabric sheaths
• Damaged wiring

If you notice any of these symptoms, it's recommended to arrange an electrical inspection to assess the safety of your wiring. In some older properties, the electrics may be connected to neighbouring homes, which can complicate the rewiring process.

If you own an older property and you’re not sure when the electrics were updated, an EICR report will confirm the condition of your wiring and provide recommendations for upgrades.

The cost of an EICR report depends on the size of your property, but it is normally priced between £80 and £300.

Electrical Safety Testing & Certification

After a full-house rewire or a major electrical project, it's essential to have the electrical system thoroughly checked out and certified. The goal is to guarantee your electrics are not only safe and reliable but also fully compliant with UK safety regulations.

Don't just think of this as a box to tick - it's actually a vital safety net for your household, your family and your property.

As soon as the rewiring work is done, a competent electrician will run through some detailed tests on your new electrical setup. This includes:

• Consumer unit check
• Checking every single socket, light, & everything else
• Checking wiring and connections

The tests are designed to catch potential issues before they become a real risk, so you know your home's electrics can handle modern gadgets and any bells and whistles you might want to add.

How much will testing & certification cost?

For a full house rewire, you can expect to pay somewhere between £200 and £500, depending on how large and complicated your property is. Some electricians will include this in the price for the wiring work, while others will charge you separately, so do check what's included when comparing quotes.

One of the key outcomes of this process is the Electrical Installation Certificate - a document from your electrician confirming that your electrical work meets all the necessary safety standards and building regulations.

This is the sort of paperwork you should keep, especially if you ever decide to sell your property. The certificate is proof that the electrical work was done by a proper tradesperson.

In addition to the installation certificate, you may also get an Electrical Installation Condition Report (EICR) - a much more in-depth report that gives a health-check of your wiring and highlights anything that might need a bit of TLC. The cost of an EICR can vary from £150 to £300 depending on the size of your property.

To ensure your rewiring work is done properly, always use a registered electrician with a scheme such as NICEIC or Part P. These bodies guarantee that your electrician has the right training and experience to do the job safely and get you the right certification.

Investing in a thorough electrical test and certification does more than just protect you from electrical hazards. It will also boost your property's value and get it ready for the modern gadgets you want to upgrade to in the years to come.

When your electrics are certified, you can rest easy knowing they're safe, efficient, and up to the job of handling everything from premium sockets to the latest smart home kit.
