Things to consider

  • How many new power sockets do you need?
  • Will any of your electrical points be installed in areas that could get wet (like a bathroom)?
  • How many rooms do you need to have rewired?
  • Do your appliances need to be tested for safety?

Electrical work – what you’re paying for

chevron

Electrical work demands skill, experience, and (in most cases) Part P certification. The last item on that list is required for electricians to self-certify that their work complies with Part P of the building regulations. Tradespeople can carry out some maintenance, repair and replacement work without this certification, but when it comes to most installation work, it’s common practice for them to be certified (unless they’re working in Scotland or Northern Ireland as the scheme doesn’t apply here). If they’re not registered, then they can carry out the work but you’ll be responsible for getting the work approved.

Each job carried out by an electrician is priced differently – according to the specifics of the work that needs to be completed. Typical tasks range from smaller, less labour-intensive jobs such as appliance testing, to larger, more complex work such as complete rewiring. This guide outlines what you can expect to pay for standard electrical work, and lists some of the considerations that can affect total costs.

 

How much does it cost to install new power sockets?

chevron

The average cost of installing new power sockets is £150.

Adding power sockets to a room is relatively cheap. The thriftiest way to increase the number of power points you have is to change single sockets to doubles.

If you want to add a new socket where one doesn’t already exist, then a spur will need to be fixed to an existing circuit. An electrician will need to access the necessary wires and then carve out (or chase) a path for wiring to the new socket, where they may need to cut into your wall or floor. This will bump up costs and walls may need to be re-plastered and flooring repaired afterwards. A cheaper alternative – though not as neat – is to hide the new wiring in a plastic conduit. This option is much quicker and will save you money.

 

How much does it cost to install an electric shower?

The average cost of installing a new electric shower is £350.

Electric showers are efficient and affordable alternatives to traditional showers, and they’re also fairly easy to install. Costs for electric shower installations will vary, but usually the installation fee will be more than the price of the shower itself due to labour time and the extra parts required to connect it. If the shower needs additional wiring, then your electrician should factor this into the cost.

For more modest budgets, it’s worth looking at shower units with entry points on the top, bottom, sides and rear. This gives your installer the flexibility to plumb in and wire it up more easily, which will reduce labour time.

Any faults with your electric shower should be inspected by a qualified electrician. Electrical issues with appliances that use water can be potentially dangerous, so it’s best to leave it to a professional. If your shower keeps tripping the power, then water could be coming into contact with the wiring. Other symptoms include burning smells, loose fittings, and a completely non-responsive shower which won’t turn on.

The most common problem with an electric shower tends to be a faulty heating element. This is generally pretty cheap and simple to fix. The pump, the control panel and the switches that control the heat and water flow are trickier (and sometimes more expensive) to repair or replace as the parts for certain showers (particularly slightly older models) can be difficult to track down.

 

How much does it cost to diagnose an electrical fault?

chevron

The average cost of diagnosing an electrical fault is £185.

Troubleshooting electrical faults requires specialist equipment, but it also needs deep knowledge and knowhow. An electrician with the right expertise will be able to review a circuit to determine exactly what is wrong – but it can take even the most experienced

professional a while to locate the source of an electrical fault sometimes. When the fault has been found, the electrician can advise on (and usually complete there and then) the necessary repairs to ensure that your household electrics remain safe.

A common cause of electrical faults and circuits shorting is large household appliances. In most cases, the diagnosis shouldn’t take more than two hours. Naturally, if you have lots of appliances and a number of different circuits throughout the house, it will take longer to diagnose and (as a result) cost more for your electrician’s time.

Repair costs can vary considerably. From a simple socket rewire to a complete system rewire, each job carries a different price tag. Your electrician should include both the diagnosis, the repair and any new parts in their quote for your job.

 

How much does it cost to rewire a room?

chevron

The average cost of rewiring a single room or circuit is £1,000.

Rewiring sounds like a formidable task but it’s actually a routine job for a competent electrician. That’s not to say it’s a small job, though. Rewiring is among the most time- and labour-intensive domestic jobs an electrician will undertake. And that makes it one of the costliest.

The cost depends on the size of the room that needs rewiring (or the number of new circuits you need). If the old wiring setup is a complete mess then this will take the electrician longer to unpick, and that may leave you with a bigger bill.

Other costs to factor in are redecorating and plastering, as your electrician may need to drill or cut into walls to rewire. To save money in the long run, if you’d also like new sockets to be installed in your home, you can ask the electrician to do this while they have access.

 

How much does installing new light fittings cost?

chevron

The average cost of installing new light fittings is £225 per light.

Adding new light fittings to your home is a straightforward job for any professional electrician. The cost of the job will very much depend on the kind of fitting that you want to have installed. A basic pendant from your bedroom ceiling can be very simple, whereas fitting a series of spotlights or downlights in your kitchen requires more preparation and installation time.

Recessed spotlights are attractive and modern, but your electrician will have to drill out individual holes for each light and then connect them to the power supply and switches. This all adds to the labour time and therefore to the overall cost of the job. Your electrician should be able to advise you on which light fittings will work best for your home, as well as how they can be connected to your existing switches.
