Part 1 of the SERT Blog Series: BS 7671 – The Road to Amendment 4 & Beyond
What is BS 7671?
BS 7671, commonly known as the IET Wiring Regulations, sets the UK standard for electrical installations. It defines the safety, design, inspection, testing and certification requirements for domestic, commercial and industrial electrical systems.
For Hampshire electricians working in Southampton, Portsmouth, Basingstoke, Winchester and the wider South-East, compliance with BS 7671 is non-negotiable. It is a legal requirement for all installation and inspection work and underpins eligibility for contracts, insurance and client approval.
Key aspects of BS 7671 include:
- Protection against electric shock and fire hazards
- Earthing and bonding requirements
- Circuit design and load calculations
- Inspection, testing, and certification standards
- Guidance on renewable and smart energy integration
Why BS 7671 Compliance is Crucial for Electricians in Hampshire
Hampshire electricians operating in social housing, FM contracts, utilities, EV installations or solar PV projects rely on BS 7671 compliance for:
- Contract eligibility: Most major contractors, housing associations and commercial clients require certified BS 7671 electricians.
- Health & safety assurance: Reduces risk of accidents, equipment damage or fire.
- Insurance coverage: Many liability and professional indemnity policies demand up-to-date BS 7671 certification.
