Building an Electrical Testing Business in the UK (EICR & PAT 2026)

1. The EICR Market: Legislation Is Your Best Sales Tool

Since 1 April 2021, all private landlords in England have been legally required to have an EICR carried out every five years, or before a new tenancy begins. Scotland introduced similar requirements in 2015. Wales followed in 2023. This created an enormous, mandatory market overnight — and most of the UK's 2.3 million private rental properties are now due for their first or second inspection.

HMO licensing adds another layer of demand. Houses in Multiple Occupation require electrical inspections as part of their mandatory and additional licensing conditions. A single licensed HMO manager with 20 properties represents 20 recurring EICR jobs, typically every 5 years.

Commercial periodic testing is the third pillar. Offices, retail units, warehouses and industrial premises are all legally required to have periodic inspections at intervals determined by their installation type. Unlike domestic landlord work, commercial testing is often done during evenings and weekends to avoid disruption — which commands premium rates.

2. PAT Testing: The Recurring Contract Goldmine

PAT testing — checking portable appliances like kettles, computers, power tools and extension leads — is technically not a legal requirement under most circumstances, but it's effectively mandatory for schools, care homes, offices and any employer who wants to demonstrate due diligence under the Electricity at Work Regulations 1989.

The key selling point of PAT testing is its annual recurrence. Once you have an account with a school, care home or office block, they need you back every 12 months. A PAT testing round at a medium-sized secondary school (400–600 appliances) takes one or two days and generates £600–£1,200 per visit — every year, without you needing to market to them again.

Care homes are particularly valuable PAT clients. Regulatory requirements from the Care Quality Commission (CQC) mean they take electrical safety seriously and rarely price-shop on testing contractors they trust.

3. Pricing: EICR by Property Type, PAT by Volume

Pricing electrical testing correctly means understanding what the market will bear and what your time actually costs.

• EICR — 1-bed flat: £90–£130. Typically 1.5–2 hours on site including report. A busy EICR electrician completes 4–5 per day.
• EICR — 3-bed house: £130–£180. 2–3 hours on site. A good target volume is 3–4 per day if geographically clustered.
• EICR — HMO per circuit: £8–£15 per circuit plus a base fee of £60–£90. A 6-circuit HMO runs to £180–£280.
• PAT testing: £1.50–£3.00 per item with a minimum day rate of £200–£350. Volume discounts for 200+ items bring the per-item cost down and still generate good daily revenue.

Offer remedial works pricing at a premium when you find C1 (danger present) or C2 (potentially dangerous) code failures. Landlords need these fixed before the property is safe — and they already trust you because you identified the issue. Remedial revenue from EICR inspections can add 20–40% to your testing income.

4. Winning Landlord and Letting Agency Accounts

The highest-leverage business development move for an electrical testing business is winning a single letting agency account. A typical mid-size letting agency manages 200–500 properties. If those properties cycle through EICR every 5 years and each generates £120–£160, that's 40–100 EICRs per year from one client relationship.

The pitch to a letting agency is straightforward: fast turnaround, reliable certification, competitive pricing and a portal where they can book, track and download certificates without calling you. Most agencies are frustrated by EICR contractors who are slow with paperwork — certificates that take 2–3 weeks to arrive are a serious pain point for agencies trying to move properties.

Target letting agencies directly — visit in person, ask to speak to the property manager, leave a one-page overview of your service and pricing. Follow up by email within 48 hours. The agencies that switch will stay with you for years if you deliver on turnaround and documentation quality.

5. NICEIC and NAPIT Registration as a Commercial Differentiator

For domestic landlord work, NICEIC or NAPIT registration is mandatory — only approved contractors can self-certify electrical work under Part P of the Building Regulations. But for testing work specifically, registration does more than ensure compliance: it's a commercial differentiator.

Letting agencies, housing associations and commercial property managers all require their EICR contractors to hold NICEIC or NAPIT (or equivalent) approved contractor status. Without it, you can't access these accounts at all. With it, you immediately qualify for a market that sole traders without registration can't enter.

NICEIC approved contractor status costs approximately £700–£1,000 per year including the initial assessment. NAPIT is typically slightly lower. Both are recoverable in the revenue from a single new letting agency account. They also grant access to the schemes' contractor finder tools, which generate inbound enquiries.

6. Scheduling Volume Testing Work Efficiently

Scheduling 40+ EICRs per week requires systems that most small electrical businesses don't have. The key is geographic batching — grouping jobs by postcode area so that each day has a logical route with minimal travel time between properties.

Letting agencies will often have their properties spread across a city. Ask for a list of all properties due for EICR in the next quarter and schedule them in postcode clusters — Monday in one area, Tuesday in another. This turns a 40-EICR month into a manageable weekly schedule rather than daily back-and-forth across town.

Use automated appointment reminders sent to tenants 24 hours before each visit. Failed access (tenant not home) is the biggest time-waster in landlord EICR work. A simple SMS reminder the day before reduces failed visits by 30–50%.

7. Trade2Base for Compliance Businesses

Electrical testing businesses have specific software needs that general job management tools don't address well: certificate storage, recurring job scheduling, and a way for letting agencies to access their certificates without calling you.

Certificate storage: Trade2Base stores EICR and PAT certificates against each property and customer record. When a letting agency needs to evidence compliance to a new tenant or local authority, they can pull the certificate from the portal immediately — without emailing or calling you.

Recurring job scheduling: Set up a 5-year recurring job for every EICR property and a 1-year recurring job for every PAT account. Trade2Base sends automated reminders to book as the due date approaches — ensuring no renewals fall through the cracks and maintaining the recurring revenue that underpins your business model.

Lettings agency portal: The Trade2Base client portal gives each letting agency a branded view of all their properties, upcoming jobs and certificates. This is the tool that makes switching to you easy and makes leaving you hard.
