What happened
BS 7671 is the national standard for electrical installations in the UK. The IET’s public edition guidance states that Amendment 4 has been published, while the previous Brown Book arrangement, including Amendment 3:2024, remains valid until 15 October 2026. Confirm the current IET position and your electrician’s agreed basis before treating transition dates as fixed for your project.
The existence of a transition period does not mean a homeowner should choose technical requirements or instruct an electrician which clauses to apply. It means the project record should be clear enough to avoid assumptions between quotation, installation and certification.
Why it matters for UK kitchen projects
Kitchen renovations can add or move circuits, sockets, lighting, extraction and fixed appliances. The electrical scope may be discussed early but carried out later, after cabinet and appliance decisions have changed.
If a quote was prepared before the new edition appeared and work is scheduled near or after the transition, it is reasonable to ask the electrician whether anything in the agreed design, materials, timing or price needs updating.
What to check in your project
Keep the electrician’s quote, scope and any revised notes. Record the appliance models and power requirements supplied to the electrician, while leaving technical design and compliance decisions to the qualified person.
At completion, retain the relevant certificates and test documentation. If different people handle first fix, second fix or later changes, make sure the latest scope and responsibility are visible to everyone involved.
