The jobs that quietly drain an electrical business rarely announce themselves. An EICR on a rental property, a consumer unit swap in a 1930s semi, a 7kW EV charger install with a standard cable run: each one looks straightforward on the day. But if your labour rate is based on what the engineer earns rather than what the engineer costs, and your flat-rate packages have not been revised since copper was cheaper, those jobs are bleeding margin without a single warning sign.
The National Living Wage changes each April. NICEIC and NAPIT registration fees, van costs, and employer pension contributions move independently of that. A price book that was built with care twelve months ago and left untouched is silently underpriced on every fixed-price job in your schedule, and the gap grows each quarter without anyone noticing until the month-end figures raise the question.
An electrical contractor price book is how you close that gap. It is the structured reference document behind every quote and invoice your business produces: loaded labour rates, material costs at what you actually pay your suppliers, markup tiers, and pre-built job cards for the work you price regularly. Pricing a consumer unit replacement or a periodic inspection starts from a verified number, not a figure someone remembers from a job last spring.
If your margins are inconsistent, your estimating is taking too long, or you are adding engineers without confidence in the numbers behind every job, keep reading.
What an Electrical Contractor Price Book Actually Does for Your Business
An electrician price book is the single source of truth behind every quote your business sends. It holds your labour rates, material costs at supplier-negotiated pricing, markup tiers for different job types, and pre-built packages for your standard work.
For any service business, pricing consistency compounds over time. In the short term, quoting from experience feels workable. Long term, the margin gaps accumulate. A price book is how you lock the maths in once and draw from it every time.
The compliance structure of UK electrical contracting adds a specific reason to formalise this. NICEIC and NAPIT registration under the Competent Person Scheme enables electrical contractors to self-certify Part P work and issue Electrical Installation Certificates without involving building control. That is a commercially valuable position, but it also means every qualifying job carries documentation requirements that have time and cost implications. The moment you start delegating quotes to someone who does not fully understand which job types sit inside and outside that scope, pricing needs to be built on structure, not on what you think the job is usually worth.
Pick Your Pricing Model Before You Build Anything
Your pricing model determines how the price book needs to be structured. When a price book does not match how you actually sell work, it creates as many problems as it solves. The underlying cost data (labour burden, materials at trade pricing, overhead allocation) is broadly the same across all models. What differs is the packaging.
Time and Materials
Time-and-materials pricing charges for actual hours worked at your loaded rate, plus materials at a marked-up cost. Your electrician price book needs two things working correctly: accurate loaded labour rates and a live supplier catalogue. When a two-hour consumer unit swap becomes four hours because the meter tails are undersized or the incoming supply needs investigation, the customer pays for the actual time.
The upside is straightforward recovery on complex jobs. The downside: customers can push back on variable final invoices, and your profitability ceiling is tied to how accurately you estimate hours upfront.
Fixed Price Per Job
A fixed-price job card sets a firm figure before your engineer arrives: one price for a single-circuit EICR on a rental property, one price for a standard 10-way consumer unit replacement, one price for a 7kW EV charger install with a standard cable run. The customer has certainty before the work begins. Your electrical service price book becomes a catalogue of pre-priced jobs, each carrying labour, materials, overhead, and your target margin.
Fixed pricing rewards efficiency. An engineer who completes a three-hour job in two and a half hours does not reduce your revenue. If the underlying cost assumptions are wrong, that is on your business, not the customer.
Good/Better/Best Tiered Pricing
Tiered pricing presents three versions of the same service at different price points, differentiated by component quality, warranty length, or scope. A consumer unit replacement might look like this: Standard (budget-grade MCBs, 12-month labour warranty), Better (full RCBO protection throughout, two-year warranty, arc-fault detection included), Best (smart consumer unit with app monitoring, three-year warranty, whole-home surge protection). Each tier needs its own pre-built job card in the price book.
This model works well for residential service work where presenting options is a natural part of the conversation. A customer who called about a tripped breaker is already open to a broader discussion about the installation's condition under BS 7671.
How Your Pricing Model Shapes Your Price Book Structure
| Model | Price Book Structure | Primary Risk |
|---|---|---|
| Time and Materials | Line-item labour rates with live material costs | Underestimating hours |
| Fixed Price | Pre-built job cards with margin embedded | Stale cost assumptions |
| Tiered (G/B/B) | Multiple pre-builds per service at different specifications | Complexity when presenting options |
Once you know your model, you know what you are building.
The Three Layers Inside Every Electrical Price Book
A price book is built from the bottom up: costs first, the customer-facing price last.
1. Loaded Labour Rate: What That Engineer Actually Costs Per Hour
The figure on the payslip is the starting point, not the number that goes into your price book. Your billable labour rates need to carry the full cost of having a qualified electrician on the job. That includes:
- Base wage
- Employer National Insurance contributions at the rate published by HMRC each tax year
- Pension contributions under auto-enrolment
- Holiday pay and leave entitlement
- Vehicle costs allocated per engineer
- Tools and PPE
- NICEIC or NAPIT registration fees and ECS card renewals
- Public liability and employers' liability insurance allocation
For most electrical contractors, the loaded rate runs between 1.25x and 1.4x the base wage. An electrician earning £22 per hour base is costing the business somewhere between £27.50 and £30.80 before a single cable is terminated. Every quote your business produces should draw from that loaded figure, not the wage line on a pay stub.
Operational fix: Set your labour rate in the price book using the fully loaded cost, then apply your markup from there. Fixed-price job cards and T&M quotes both draw from that loaded figure consistently, without anyone recalculating it by hand on each estimate.
2. Material Costs: Cable, MCBs, and Consumer Units at What You Actually Pay
Material costs in your price book should reflect what you actually pay your preferred suppliers after negotiated trade discounts. Not the counter price. Not a figure from a quote you submitted six months ago.
