Electrical Contractor Business Data Guide: Profitability and Growth for UK Electricians
Electrical contracting covers everything from consumer unit upgrades to large commercial installations. Contractors who track job margin by category, engineer productivity, certification revenue, and contract pipeline build businesses that scale profitably rather than just getting busier.

Revenue Categories in Electrical Contracting#
UK electrical contractors typically generate revenue across several distinct categories: residential remedial and upgrade work, new-build wiring, commercial fit-out and maintenance, EV charger installation, periodic inspection and testing (PIR/EIC certification), and specialist work such as fire alarms, security systems, or data infrastructure. Each carries different margin profiles and demand patterns. Tracking revenue and margin separately by category reveals where your business is commercially strongest.
Job Cost Tracking by Work Type#
Post-job cost analysis is the foundation of electrical contracting profitability management. Track actual labour hours against quoted hours, materials used versus ordered, any subcontractor costs, and certification fees for every job. Jobs that consistently overrun on labour include first-fix in older properties with inadequate existing wiring, consumer unit upgrades in properties with non-standard boards, and commercial fit-out in occupied buildings with restricted access. Recognising these patterns in your data lets you quote them accurately.
Engineer Utilisation and Billable Hours#
Track billable hours per engineer per week versus total working hours. The gap represents travel, admin, quoting time, and any idle periods. A target of seventy-five to eighty percent billable utilisation is typical for a well-organised electrical team. If utilisation is below this, examine whether job sequencing and scheduling is efficient, whether van stock levels are sufficient (parts runs destroy utilisation), and whether engineers are spending excessive time on non-billable administrative tasks.

Certification and Testing Revenue#
Electrical Installation Condition Reports (EICRs) for rental properties are legally mandated every five years, making this a predictable, recurring revenue stream. Track EICR bookings per month, average fee, and conversion rate from EICR to remedial work. Many contractors find EICR work converts to fifty to seventy percent additional remedial jobs, making it both a standalone revenue stream and a lead generation mechanism. Track your remedial conversion rate and average remedial value to understand the full EICR customer value.
Commercial Contract Portfolio#
Commercial electrical maintenance contracts with offices, retail, hospitality, and industrial clients provide predictable recurring revenue. Track number of contracts, annual contract value, renewal rate, and margin per contract. Contracts priced correctly and managed efficiently outperform reactive residential work on margin consistency. Build a target commercial contract value and track progress toward it quarterly.
EV Charger and Renewable Installation Growth#
EV charger installation is one of the fastest-growing segments in electrical contracting. Track EV charger installations per month, average revenue per installation, and add-on work generated (consumer unit upgrades, earthing improvements). Monitor how much of your EV work generates OZEV grant eligibility for customers — this affects your competitive positioning. Solar panel electrical connection work is a similar growing category to track separately.
Materials Procurement and Markup Management#
Materials are typically thirty to forty percent of a residential electrical job cost. Track your effective materials markup — the difference between trade cost and what you charge clients — across all jobs. Some contractors quote materials at cost and rely on labour for all margin; others apply a standard twenty-five to forty percent markup on materials. Track your actual markup realisation versus your target and adjust if materials are being under-charged on specific job types.
NICEIC or NAPIT Compliance and Scheme Benefits#
Registration with NICEIC or NAPIT is both a compliance requirement and a marketing asset. Track your annual vetting assessment outcomes, any non-conformances and their resolution, and the business generated through the scheme's consumer-facing directories. Many customers specifically search for NICEIC-registered contractors — track how much of your inquiry volume cites your registration as a reason for contact.
People also ask
What profit margin should an electrical contractor make in the UK?
UK electrical contractors typically aim for 15 to 25 percent net margin. Commercial and specialist work tends to achieve higher margins than competitive residential jobs. EICR testing and remedial work is often the most consistent margin category for established businesses.
How do electrical companies get commercial contracts in the UK?
Through direct relationships with facilities managers and property managers, framework agreements with local authorities and housing associations, tender submissions on commercial projects, and referrals from main contractors. NICEIC or NAPIT registration and adequate PLI (typically £5m) are often required.
How much do electricians charge per hour in the UK?
UK electrician rates range from £45 to £90 per hour for standard work. Specialist electricians (industrial, data infrastructure, fire alarms) command higher rates. London and the South East typically sit at the upper end. Out-of-hours emergency rates are usually 1.5 to 2x standard rates.
