Replace a power socket

Trade: Electrician

⭐ Introduction

Replacing a power socket is a common electrical job in UK homes, usually needed when an old socket is faulty, damaged, or you want to upgrade to a newer, safer model. It might also be required if you’re changing your home’s décor and want sockets that better fit your style or location.

Sockets can wear out over time, develop loose connections, or fail to provide a reliable supply of electricity. For safety, it’s important to address issues promptly, as faulty sockets can cause electric shocks or fires. Sometimes, upgrading to sockets with built-in safety features — such as switched or USB sockets — is a good reason for replacement.

If you’re unsure about the condition of your sockets or want an upgrade, a qualified electrician can help safely and efficiently.

🔧 What the job involves

Simply put, replacing a power socket means removing the existing socket unit and installing a new one in its place. The electrician will:

  • Turn off the electricity supply to the circuit to work safely.
  • Remove the existing faceplate and socket mechanism from the wall box.
  • Inspect the wiring and ensure it’s safe, correctly connected, and suitable for the new socket.
  • Fit the replacement socket, securing it to the back box and attaching the wiring correctly.
  • Check the socket functions properly and is safe to use.
  • Restore the power, test the socket, and tidy up the work area.

If the old socket or wiring has faults, additional repairs might be needed. Also, if the socket location needs changing or upgrading to, for example, a fused connection unit or USB charging socket, extra work is involved.

In all cases, compliance with UK electrical safety standards (BS 7671 Wiring Regulations) is essential. A registered electrician will ensure the new socket meets these requirements.

📝 Step-by-step from booking to completion

  1. Initial enquiry: Contact a qualified electrician or local electrical company and explain your needs (replacement location, type of socket, any current problems).
  2. Survey and quote: The electrician may visit your home to assess the existing installation and provide a written quote. This visit is often free and includes a safety inspection.
  3. Booking the job: Agree on a convenient date and time for the work. Ensure the electrician is registered with a competent person scheme, such as NICEIC or ELECSA.
  4. Preparation: On the day of the job, clear access to the socket area. The electrician will switch off your power at the consumer unit (fuse box).
  5. Socket replacement: The electrician works carefully to remove and replace the socket, tests all connections, and completes any paperwork required.
  6. Testing and certification: They will test the socket and may issue an Electrical Installation Condition Report (EICR) or a minor works certificate if required.
  7. Completion: The electrician restores power, double-checks functionality, and cleans the work area. You’ll be advised on any aftercare or warranty details.

💷 Main costs to expect

  • Labour: Typically the largest part, charged by the hour (£40–£70/hour is common). A basic socket replacement can take 30-60 minutes.
  • Materials and parts: New socket unit(s) cost £5–£15 each, depending on style and features (standard, switched, USB).
  • Additional parts: If new wiring or back boxes are needed, expect extra charges (£10–£25 per item).
  • Disposal: Minor charge or included in labour for disposing of old sockets.
  • Certification: Certificate or report may cost £20–£50 if provided separately.

Example:

  • Labour (1 hour): £50
  • New switched socket: £10
  • Miscellaneous parts: £10
  • Certification: £30
  • Total: Approx. £100

📊 What affects the price

  • Accessibility of the socket (easy access vs. tricky locations).
  • Complexity of wiring (simple cable vs. needing new cables or trunking).
  • Type of socket being installed (standard, switched, USB, weatherproof).
  • Compliance with regulations, especially if the installation is part of a larger electrical upgrade.
  • Any remedial electrical work required, such as fixing circuit faults.
  • Geographic location (labour rates vary across the UK).
  • Timeframe — emergency or out-of-hours work costs more.

⏱ How long does it take?

  • Straight replacement: 30–60 minutes. This covers simple removal and swapping without additional repairs.
  • Socket upgrade or relocation: 1–3 hours, depending on extra wiring, plastering, or trunking needed.
  • Complex install: If circuits need major work or certification paperwork is involved, expect longer.

Your electrician should give you an estimated time before starting.

🏠 Can you DIY it?

It’s strongly recommended not to replace power sockets yourself unless you are a qualified electrician. UK law requires electrical work in domestic premises to comply with Part P Building Regulations. Unsafe or poorly connected sockets can cause serious injury or fire.

Qualified electricians follow BS 7671 standards and test installations with specialised equipment. If you do minor electrical work, you must notify your local building control and arrange for inspection, which is often complicated and risky to manage without experience.

For safety and legal reasons, hire a registered electrician to replace sockets.

💰 Typical UK price range

Most homeowners can expect to pay between £80 and £150 for replacing a standard power socket, including labour and parts. Prices include VAT at 20%. More complex jobs, such as installing USB sockets or relocating sockets, may cost more.

Always get a written quote and confirm what is included before proceeding.

✅ Handy tips before you start

  • Clear furniture or obstacles from around the socket to give the electrician easy access.
  • Check your electrical consumer unit is labelled so power can be quickly isolated.
  • If you want specific types of sockets (e.g., with USB, weatherproof), mention this early when enquiring.
  • Keep all paperwork, including receipts and certificates, in a safe place for future reference or when selling your home.
  • Ask about warranties on parts and workmanship. Most electricians will guarantee their work for at least 12 months.
  • Do not use a socket that shows signs of damage—replace it promptly to avoid hazards.

By preparing well and using a competent electrician, socket replacement is straightforward, safe, and adds convenience and safety to your home electrical system.
