EICR Testing Guide (2025) — for Landlords & Commercial Sites
Everything you need to know about Electrical Installation Condition Reports (EICR), including BS 7671:2018 requirements, legal obligations, costs, and testing procedures.
Quick Answers
What is an EICR?
An EICR is an MOT for the fixed wiring in your property. A qualified electrician checks the consumer units, circuits, earthing/bonding and safety devices against BS 7671, then issues a report marked Satisfactory or Unsatisfactory with any issues listed.
Common issues we find
Overloaded circuits, damaged/aged cabling, poor earthing/bonding, DIY alterations, missing RCD protection.
How the EICR works
1Plan & prepare
We agree a low-disruption slot, confirm access to all boards/rooms, and notify occupants (brief power-offs needed).
2Inspect & test
Visual checks, dead tests (continuity, insulation), live tests (RCD trip, loop impedance), open boards where safe.
3Plain-English report
Satisfactory or Unsatisfactory with clear actions and recommended re-test date.

Legal Requirements
| Property type | What the law/guidance expects | Typical interval |
|---|---|---|
| Private rented homes (England & Wales) | 5-yearly EICR; give report to tenant; fix C1/C2 promptly | 5 years |
| Private & social rented (Scotland) | Electrical safety inspection incl. EICR (plus PAT if you supply appliances) | 5 years |
| Private rented (N. Ireland) | New tenancies from 1 Apr 2025; all existing by 1 Dec 2025 | 5 years |
| Commercial/workplaces | Maintain safely (H&S/EAWR). Insurers usually require current EICR | 5 years (risk-based) |
| Owner-occupied homes | Not mandated; recommended for safety | 10 years |
If your environment is harsh/heavy-duty (industrial, wet, corrosive, outdoor), your engineer may recommend a shorter interval (e.g., 3 years).
England (Private Rentals)
- EICR required every 5 years for all privately rented residential properties
- Legal requirement since July 2020 (new tenancies) and April 2021 (existing)
- Copy of report must be given to each tenant
- C1: make safe immediately; C2: remediate within 28 days (or sooner if specified)
- Fines up to £30,000 for non-compliance
Wales (Private & Social)
- All landlords (private and social) must ensure 5-yearly electrical inspections
- Renting Homes (Wales) Act 2016 in effect since December 2022

Northern Ireland (NEW 2025)
🆕 New legislation phasing in 2025 under Private Tenancies Act (NI) 2022
- 1 April 2025: Valid EICR required for all new private tenancies
- 1 December 2025: Existing tenancies must have EICR
- 5-yearly inspections required, mirrors England's regulations

Commercial Properties & Workplaces
For offices, shops, industrial units, and other commercial premises, there isn't a specific "5-year EICR law" like in residential, but owners and employers have legal duties under health and safety regulations.
- Health & Safety at Work Act 1974 compliance required
- Electricity at Work Regulations 1989 duties
- 5-year EICRs considered best practice and often required by insurers
- Fire risk assessments often require current electrical certificates
- High-risk environments may need more frequent testing (3-yearly or annual)
- Enforcement action and liability risks if accidents occur
Legal Consequences of Non-Compliance
Residential Rental Penalties:
- • Fines up to £30,000 (England); Wales: property may be deemed unfit for habitation
- • Difficulty serving valid eviction notices
- • Local authority enforcement action
- • Insurance claims may be invalidated
Commercial/Workplace Penalties:
- • Unlimited fines for serious electrical safety breaches
- • Criminal prosecution under Health & Safety legislation
- • HSE improvement and prohibition notices

Things to Consider for Your EICR
Most delays aren't electrical—they're administrative. These optional services help avoid common issues like unlabelled boards, unclear responsibilities, and unresolved investigation items.
Distribution Board Labelling
Unlabelled circuits mean guesswork and accidental shutdowns. Get durable printed labels, clean front schedules, and photographed circuit records.
Same-Day C1 Safety Repair
Minor C1 defects get fixed immediately instead of being isolated, keeping your circuits in service while maintaining safety.
FI Fast-Track Investigation
Avoid "unsatisfactory" reports that drag on. Ring-fence investigation time to resolve FI items during the same visit where possible.
Free Logbok™ Trial
All your EICR documentation, photos, and schedules uploaded to secure cloud storage with automated reminders for future tests.
Compliance Saver Pack
Save time and avoid second visits with our bundled package: DB labelling (up to 3 boards) + FI fast-track (1 FI) + Logbok trial.
Leave with a clean schedule and clear action plan
Note: Minor materials included. Work must be safe to complete within pre-authorised limits with parts available. Larger works or notifiable changes are quoted separately. If access, permits, or shutdown windows are needed, we'll plan them with you.

Understanding Results
Your EICR provides a comprehensive assessment of your electrical installation's condition. The report includes visual inspections, test results, and an overall outcome that determines whether remedial work is needed.
Satisfactory Report
The electrical installation is in a satisfactory condition for continued use. Any observations noted are minor and don't require immediate action.
What this means:
- • Installation is safe for continued use
- • No urgent remedial work required
- • Next inspection due in 5 years (or as recommended)
- • Certificate valid for insurance and legal compliance
Unsatisfactory Report
The electrical installation has one or more defects that require remedial work. The severity depends on the classification codes assigned.
What this means:
- • Remedial work required before continued use
- • Action timeframes depend on defect severity
- • May need re-inspection after remedial work
- • Certificate shows limitations until fixed
