Electrician Cost Calculator

Understanding Electrician Costs in the UK (2025)

Hiring a professional electrician is one of the most important home improvements you can make. Electrical work is not only complex but also potentially dangerous if handled incorrectly. Costs vary widely depending on job complexity, property size, urgency, and location. Older properties often require more labour and materials, while new builds are usually quicker and cheaper to wire.

Our electrician cost calculator helps you estimate the cost of common electrical jobs, from simple socket installations to full house rewires. Using a certified electrician ensures your work complies with UK regulations, such as Part P of the Building Regulations, and provides peace of mind that the job is safe and correctly installed.

What Affects Electrician Costs?

Regional Labour Rates

Electrician hourly rates vary across the UK. London electricians charge £55-75 per hour, South East £45-65, Midlands £35-50, and Northern or rural areas £30-45. Labour rates account for most of the total cost, so location heavily impacts the estimate. Our calculator factors in your postcode for more accurate results.

Emergency Call-Outs

Emergency electrical work usually comes at a premium due to immediate safety risks. Same-day service can add 30% to standard rates, while critical emergencies such as exposed wires, power outages, or burning smells may cost 80-100% more. Call-out fees typically range from £70-120 depending on time and region.

Certification and Testing

Most electrical work requires certification under Part P regulations. Electrical Installation Certificates typically cost £150-250, Minor Works Certificates £50-100, and periodic inspections (EICR) usually range £150-300. Hiring a qualified electrician ensures all certifications are valid and recognised by insurers.

Installation Complexity & Cable Routes

The cost of electrical work often depends on how the cables are installed. Surface-mounted wiring is cheapest and quickest, while chasing walls or running cables under floors can significantly increase labour costs.

• Surface-mounted: Quickest & cheapest, typically 30-40% less than concealed wiring.
• Chased & concealed: Common in most homes; adds 40-60% labour.
• Underfloor / Ceiling routes: Most time-consuming; can add 60-100% to costs.

When Electrical Work Must Be Notified

Certain electrical work must be notified under Part P of the Building Regulations. Notifying ensures work is safe, legal, and certified. Examples include:

• New circuits or consumer unit replacements
• Work in kitchens or bathrooms
• Outdoor electrical installations
• EV charger installations

Non-notifiable work includes like-for-like replacements outside kitchens or bathrooms but still must comply with BS 7671 regulations.

Full or Partial Rewire Costs

A full house rewire replaces all circuits, while partial rewires focus on problem areas. Below is a typical cost breakdown by property size and estimated days of work.

EV Charger Installation Costs

Electric vehicle charging points are increasingly popular, and installation costs vary by charger type, supply, and cable run length.

• 7kW charger: £800-1,200 installed (if consumer unit is suitable and cable <10m)
• 22kW three-phase charger: £1,200-1,800 (requires three-phase supply)
• Consumer unit upgrade: add £300-600
• Cable run >10m: add £100–200 per extra 10m

Some EV charger installations may qualify for government grants. Check the Electric Vehicle Chargepoint Grant for eligibility and funding.

Finding a Qualified Electrician

Hiring a certified electrician ensures safety, compliance, and high-quality workmanship. Look for professionals with proper qualifications and insurance.

• Registration with competent person schemes: NICEIC, NAPIT, or ELECSA.
• Public liability insurance (£2M+) & professional indemnity.
• Relevant qualifications (NVQ3, City & Guilds 2391 / 2382 where relevant).
• Check recent reviews, references, and ask for certificates (EIC / EICR / Minor Works Certificates).

Money-Saving Tips

• Combine multiple small jobs into one visit to save call-out fees
• Plan work to minimise cable runs & complexity
• Consider partial rewires for problem areas
• Schedule non-urgent work during normal hours
• Get multiple quotes & verify qualifications
• Prepare access & clear work areas to reduce time on site
