Here’s a question worth sitting with: are you still qualified to do all the work you’ve been doing for years?
For most electricians, the honest answer used to be yes without much thought. In 2026, that answer requires a closer look. Three regulatory events are converging this year in a way that hasn’t happened before : a wave of EICR renewals already under way, a change to competency rules that rewrites who can sign off certain work from October, and a new edition of the wiring regulations that replaces the book on your shelf in the same month.
None of these is small on its own. Together they represent the biggest shift in how electrical contractors operate in England since the original rental sector EICR rules came in.
If you run a small electrical business with employed engineers or CIS subcontractors, all three affect you directly.

The EICR renewal cliff
Five years ago, the industry saw a last-minute rush as thousands of landlords scrambled to meet the April 2021 deadline when EICRs became mandatory for existing tenancies. As the deadline approached, demand surged. Engineers spiked their prices, appointments became scarce, and landlords faced fines of up to £30,000 per property for non-compliance.
That wave is back. April 2026 marks the first major renewal point. All the certificates issued during that original 2021 rush are now hitting their five-year expiry simultaneously. The private rented sector covers 4.7 million households in England alone, according to the English Private Landlord Survey 2024. Most of those certificates are due.
This time the conditions are harder. Industry observers estimate there are around 25% fewer working electricians than in 2021, with a large proportion now focused on solar PV, EV charging, and energy storage work. The same demand is chasing a smaller pool of qualified engineers.
Then add the social housing extension. From November 2025, England’s social rented sector (approximately four million properties) came under the same mandatory five-year EICR rules that have applied to private landlords since 2021. Existing tenancies must be covered by May 2026. Northern Ireland extended mandatory EICRs to all existing private tenancies from December 2025. Scotland and Wales have their own equivalent rules already in place.
The fine for non-compliance was increased from £30,000 to £40,000 from November 2025, per gov.uk guidance. Enforcement by local authorities has tightened.
Don’t overlook the 28-day remedial window. When an EICR comes back with C1 or C2 codes, the landlord has 28 days to complete remedial work. For an electrical business, that means the renewal wave creates both testing volume and a follow-on wave of repair jobs that need to be resourced and scheduled alongside the inspections themselves. Businesses with the capacity for both will take the lion’s share of the work. Those who can only test will lose the remedial revenue to other contractors.
Set up your EICR renewal pipeline now. Contact every landlord you tested in 2021 and offer renewals before the market saturates. The businesses doing that today will control their own diaries through 2026. Waiting for the phone to ring puts you at the same disadvantage as the landlords who waited until the last minute in 2021.
Repeat EICRs also tend to run more efficiently than first-time inspections. When you know the property, know the tenant, and have the previous test results on file, the process is faster, more consistent, and more cost-effective for the customer. For a job management system that stores previous certificate data and can trigger renewal reminders automatically, that’s a natural part of how the workflow runs.
The EAS changes: individual competency from October 2026
Of the three changes this year, the EAS update has generated the most anxiety in the trade. Some of that reaction is understandable. One electrician reported paying £4,400 to retrain after his scheme provider determined it no longer recognised his existing qualifications.
Updated in October 2024, the Electrotechnical Assessment Specification shifts the competency model from firm-level to individual. Previously, a business could rely on one Qualified Supervisor with the appropriate qualifications to cover the work of multiple operatives. From 1 October 2026, that model ends for specific categories of work.
Every “employed person” carrying out work in the affected categories must hold their own Level 3 qualification and demonstrate at least two years of relevant experience. Employed person includes PAYE staff, CIS subcontractors, agency workers, sole traders, and anyone else engaged by your business to perform that work, as stated in the official NICEIC EAS guidance.
Work categories affected from October 2026:
- Periodic inspection and testing (EICRs)
- EV charging installations
- Solar PV systems
- Electrical energy storage systems (battery storage)
- Micro wind turbine installations
For EICR work specifically, this ends the experience-only route. At present, an electrician can carry out EICRs without holding a formal Level 3 inspection and testing qualification, provided they can demonstrate adequate experience. That route closes on 1 October 2026. After that date, the City & Guilds 2391-52 or an equivalent Level 3 award is required, along with documented evidence of two years’ experience in periodic inspection work.
The enforcement timeline has been phased. October 2024 was the awareness phase: assessors began flagging qualification gaps. October 2025 to October 2026 is the improvement phase, where development points are being recorded on assessment reports. October 2026 is the hard deadline. Non-compliance after that date risks having specific work categories removed from your firm’s registration scope. Persistent non-compliance can result in complete withdrawal of competent person scheme registration.
Industry voices are divided on this. Some see it as overdue. The argument that people with the right qualification are doing things properly and those without it may not be has genuine force. Others worry about whether the costs of retraining will simply be absorbed by contractors without any corresponding increase in what they can charge for EICR work, particularly in a rental sector under heavy financial pressure.
Neither concern is wrong. The deadline, though, doesn’t move.
The practical risk for contractors isn’t just compliance. It’s capacity. If you have engineers who currently carry out EICRs or low-carbon technology installations without the required Level 3 qualifications, and they haven’t started training, they are running out of runway. Training providers are already warning of course bottlenecks as the deadline approaches. An engineer who starts a Level 3 qualification course in August 2026 may not complete and certify before October.
Businesses that need to audit their workforce now should be asking three questions. Which of my engineers carry out EICRs? Which carry out EV, solar, or battery work? Do each of them individually hold the required Level 3 qualification for those categories? If any answer is no, training needs to be booked.
For a full list of acceptable qualifications by work category, the ECA’s guidance on EAS changes and the IET’s EAS qualifications guide are the primary references. City & Guilds and EAL are the main awarding bodies.
BS 7671 Amendment 4: the Orange Book
Amendment 4 to the 18th Edition Wiring Regulations (BS 7671:2018+A4:2026) published on 15 April 2026. That’s the Orange Book.
Its predecessor, the Brown Book, runs in parallel until 15 October 2026, at which point it is withdrawn and all new work must comply with Amendment 4. As one IET committee manager put it at the launch: what would be the alternative? We could sit still for ten years, keep the same book, and in that time the rest of the world keeps moving. By the time we came to update it, the uplift required would be enormous. Standardisation doesn’t stand still.
For most electricians doing standard domestic wiring without batteries, PoE, or medical location work, the day-to-day impact is limited. If you’re already working carefully to Amendment 3, you’re probably 90% of the way there already. The core protection requirements (max Zs, disconnection times, RCD types) haven’t changed.
What has changed matters most for anyone installing the technologies that are growing fastest in the domestic and commercial market.
Chapter 57: stationary secondary batteries
This is the most substantial new addition in Amendment 4 and addresses the rapid growth in battery energy storage systems being installed alongside solar PV. For the first time, BS 7671 has a dedicated chapter covering stationary secondary batteries: domestic BESS, commercial energy storage, and grid-connected arrays.
Batteries are fundamentally different from other electrical loads. Voltage is always present. You can’t simply isolate the circuit at the consumer unit and assume the system is dead. High DC fault currents, thermal effects, and the risk of thermal runaway all create hazards the existing regulations never covered. That’s why this chapter was needed.
Chapter 57 introduces specific requirements for ventilation (batteries can emit gases during charging and in fault conditions), location restrictions (not in bedrooms, not on escape routes, not in lofts, with reference to PAS 63100 for domestic installations), isolation arrangements at both ends of the power circuit, and identification notices at the consumer unit and battery location so future electricians and emergency services know what they’re dealing with.
Battery installations will increasingly mirror EV charger installs: more paperwork, defined zones, and an emphasis on fire safety, all with direct implications for how you quote, plan, and complete this type of work.
EICR form changes: C1/C2 and FI decoupled
There’s a change to the EICR form that every inspector should understand before October. The model forms in Appendix 6 have been updated to separate C1 and C2 observations from C3 and FI codes on the report.
The logic matters. A C1 or C2 code makes a report unsatisfactory. A C3 or FI does not. Previously, FI (Further Investigation) sat alongside C1 and C2 in a way that made it easy to misread the outcome, and according to those who developed the change, the FI code was being used by some contractors as a way to generate additional work from clients without a genuine unsatisfactory finding to justify it.
Under Amendment 4, the FI code wording changes from “further investigation required without delay” to “further investigation is advised.” It is placed alongside C3 in its own section, making clear to the client that it doesn’t affect the report outcome. The onus shifts to the client to decide whether they want to pay for additional investigation.
Other changes relevant to everyday work
Section 716 is an entirely new section covering Power over Ethernet, recognising that PoE cables now carry both data and power, and that thermal considerations apply when cables are grouped or run in bundles. If you’re installing smart home systems, security cameras, or access control that uses PoE, this section is relevant to your work.
Section 710 (Medical Locations) has been substantially expanded, including a new model form for recording supplementary bonding test results. Small clinics and dental practices now face more rigorous documentation requirements.
The term “isolator” has been deprecated. It’s now a “disconnector” (for offload switching) or a “switch disconnector” (for onload switching). A small change, but one that will show up in documentation and scheme assessments.
The practical overlap
Three compliance events. One year. They’re connected.
The EICR renewal surge creates the most immediate revenue opportunity. But from October 2026, the engineers carrying out those EICRs must individually hold Level 3 qualifications. And the certificates they issue will need to comply with the Amendment 4 EICR form format, including the decoupled C1/C2 and FI sections.
An electrical business that goes into October 2026 with undertrained staff, old EICR forms, and no renewal pipeline in place is exposed on all three fronts simultaneously.
For the businesses managing this well (qualified engineers, a scheduled renewal programme, job management that stores certificates and tracks qualification expiry dates), 2026 is a major commercial opportunity. The renewal volume is real. The competition from less-prepared contractors will thin. The contractors who show landlords and letting agents a professional compliance service with digital records, structured renewal reminders, and rapid remedial turnaround will lock in recurring relationships.
Wiring regulations will always keep moving. As the IET put it: the technology coming through has to be dealt with in the standard, and the technology won’t stop. That’s not a complaint. It’s the nature of an industry expanding faster than it ever has.
Are you going to be ahead of these changes when October arrives, or behind them?
What to do before October 2026
Audit your workforce against the EAS requirements. For every engineer who carries out EICRs, EV charging, solar, or battery storage work, confirm they individually hold the required Level 3 qualification. For EICRs, that means City & Guilds 2391-52 or equivalent, plus documented evidence of two years’ experience in periodic inspection. If gaps exist, book training now. Course availability will tighten considerably in the run-up to October.
Build your EICR renewal pipeline. Pull every EICR your business completed in 2021 and contact those clients now. The landlords who got their first certificates in the 2021 rush are already in the renewal window. Offering early booking before the market saturates protects your diary and gives clients a better experience than scrambling for a last-minute appointment.
Get hold of the Orange Book and understand what changes affect your work type. The Brown Book is valid until 15 October 2026. From 16 October, all new work must comply with Amendment 4. If you install batteries, solar, or PoE systems, Chapter 57 and Section 716 need attention before then. Update your EICR forms to reflect the new Appendix 6 format.
Make sure your documentation processes can support the new requirements. Amendment 4 increases the paperwork load for battery and PoE installations. The new EICR form separates observation categories. Medical location work now requires additional bonding test schedules. Paper-based systems will struggle. Digital job management with built-in certificate generation, stored asset records, and renewal prompts will handle this without adding admin burden to engineers on site.
