New BSI Standards in 2026:
What Every Tradesman Needs to Know

It’s been a busy couple of years at the British Standards Institution. Between Amendment 4 to the Wiring Regs, a brand new fire risk assessment standard, and the Future Homes Standard looming over every heating engineer in the country, there’s a lot to get your head around.

Don’t worry — we’ve broken it down trade by trade, with the dates that actually matter and the stuff you need to do now rather than in a panic later.

Electricians: Amendment 4 Is Here

Amendment 4 to BS 7671:2018 — the 18th Edition of the IET Wiring Regulations — was signed off in January 2026. The previous version gets withdrawn six months after publication, with 1 October 2026 as the hard cutoff for all new work.

What’s actually changed?

Individual competence is tightening

The biggest practical change? You can no longer rely solely on a Qualified Supervisor to sign off your work if you’re a subcontractor. High-risk work — solar PV, EV charging, EICRs — now requires individual Level 3 qualifications with relevant experience.

EAL will launch replacement Level 3 qualifications in April 2026, with current certification closing on 31 December 2026. Don’t leave it until November.

Gas & Heating Engineers: The Future Homes Standard Changes Everything

The Future Homes Standard isn’t a BSI standard per se, but it leans heavily on British Standards for compliance, and it’s about to reshape the heating trade entirely.

What’s happening?

The Future Homes Standard is expected to take effect from 2027, subject to legislation being enacted and a transition period. When implemented, new-build homes will no longer be permitted to install gas boilers as standard. Developers will need to install low-carbon heating — primarily heat pumps — targeting a maximum flow temperature of 55°C for wet central heating systems. The exact implementation date and transition arrangements are still subject to parliamentary approval.

The Government expects this to triple the heat pump market from around 100,000 to 300,000 installations per year. That’s a lot of new work — but only for engineers who are qualified to do it.

What this means for gas engineers

Let’s be clear: gas isn’t going away overnight. The existing housing stock still runs on gas, and CP12s, boiler servicing, and gas safety work will be needed for decades. But the direction of travel is obvious, and diversifying into heat pump installation is no longer a “nice to have” — it’s career insurance.

If you’re already doing gas safety certificates, that work continues as normal. Your CP12 landlord safety records, gas tightness testing documentation, and appliance commissioning certs aren’t going anywhere. But adding heat pump competencies — through training providers like GTEC, Logic4Training, or the Ground Source Heat Pump Association — puts you in a much stronger position.

Fire Safety: BS 9792 Replaces PAS 79-2

If you do any fire risk assessment work in housing — HMOs, blocks of flats, sheltered accommodation — BS 9792:2025 landed in August 2025 and formally replaces PAS 79-2:2020.

Key changes

• Standardised pro forma. No more inconsistent report formats. BS 9792 introduces a structured method for assessing and documenting findings.
• Person-centred fire risk assessments (PCFRAs) are now essential for supported housing, extra care, and sheltered accommodation — not optional.
• Stronger evacuation guidance with a new annex focused on residents with specific evacuation needs.
• Legal alignment with the Building Safety Act 2022 and related post-Grenfell legislation.
• Assessor competence requirements are explicitly spelled out — you need to demonstrate understanding of fire safety principles, legislation, and the ability to adapt recommendations to specific risks.

What’s coming next?

BSI’s fire safety standards roadmap for 2026–2027 includes:

Building Competence: BS 8670-2 (2026)

Worth a quick mention: BS 8670-2 is due in 2026 and will set out core competencies for anyone working with construction products. It’s part of the broader post-Grenfell push to formalise who’s qualified to do what — and it can be integrated into existing competence frameworks.

This won’t change your day-to-day immediately, but it signals where the industry is heading: more documentation, more proof of competence, and less room for “we’ve always done it this way.”

Key Dates at a Glance

The Practical Takeaway: Documentation Is Your Armour

Here’s the pattern across all of these changes: the standards are getting more specific about what you record, how you record it, and whether you’re qualified to sign it off.

Whether it’s Amendment 4 requiring individual Level 3 qualifications, BS 9792 mandating standardised fire risk assessment pro formas, or the Future Homes Standard creating entirely new categories of heating work — the common thread is that your paperwork needs to be right, thorough, and traceable.

Four things to do now

1. Know your deadlines. Amendment 4 hard cutoff is 1 October 2026. BS 9792 is already live. Future Homes Standard implementation is rolling out through 2026–2027.
2. Check your qualifications. If you’re doing EICRs, solar, or EV work, verify your Level 3 certs are current and will map to the new requirements.
3. Update your templates. Old certificate formats won’t cut it. Make sure your documentation reflects the current standard, not the one you qualified under.
4. Use tools that keep up. This is where digital certification pays for itself. Standards change — your cert tool should update to match, so you’re always issuing compliant documentation without manually tracking every amendment.

Stay Ahead, Not Behind

Standards updates can feel like a nuisance, but they’re also an opportunity. Every time the bar rises, the tradespeople who clear it first get the best work. Landlords want engineers who are up to date. Commercial clients want electricians who know Amendment 4 inside out. Housing associations want fire risk assessors working to BS 9792.

Being current isn’t just about compliance — it’s a competitive advantage.
