Most electricians set their day rate by looking at what others charge and picking a similar number. This is a mistake. Your day rate should be calculated from your costs upward, not from the market downward. Here is the correct method:
- Target annual income: What salary do you want to take home? Include employer NI contributions, pension contributions, and student loan repayments if applicable.
- Annual business costs: Van (finance, insurance, fuel, maintenance, MOT), tools and equipment (purchase and calibration), insurance (public liability, professional indemnity), competent person scheme (NICEIC, NAPIT), accountant, phone and IT, workwear and PPE, marketing, and training/CPD.
- Non-billable days: You cannot bill for every day of the year. Deduct weekends (104 days), bank holidays (8 days), annual leave (20-25 days), sick days (5-10 days), admin and quoting time (15-25 days), and training days (5-10 days). Most self-employed electricians have 200 to 220 billable days per year.
- Profit margin: Add 10-20% profit margin on top. Profit is not the same as your salary — it is the return on the risk and capital you invest in the business.
Example calculation: Target income £45,000 + employer NI £5,000 + pension £3,000 + business costs £18,000 = £71,000 total. Divided by 210 billable days = £338 per day before profit. Add 15% profit = £389 per day. If you are charging less than this, you are either undercharging or your costs are lower than average.
