UK prescribed cable zones before drilling: where cables are most likely, not ‘safe’

This guide keeps the scope narrow: it answers the search question, separates confirmed evidence from assumptions, and avoids treating a product page as proof for claims it does not make.

The BuildWiz UK is used here for: BuildWiz UK summarises BS 7671 prescribed zones and detector limitations before drilling.. The SELECT technical pocket guide PDF is used here for: SELECT pocket guidance restates zone geometry for cables concealed at less than 50 mm depth..

Decision Checklist

• Direct answer: prescribed zones are expected cable routes, so treat them as higher-risk drill areas.
• Local constraint: 150 mm top strip, corner strips, and horizontal/vertical lines from accessories.
• Decision path: map sockets/switches first, then scan intended hole, then decide drill/stop.
• Thin-wall note: walls ≤100 mm may extend zones to the reverse side.
• FAQ only for older DIY wiring exceptions and detector false confidence.

Evidence Boundaries

• Use the cited source and the site evidence only.

What Not To Assume

• Avoid give legal certainty that any zone is empty; older and DIY wiring can deviate.
• Avoid claiming a consumer detector proves a wall is clear of live cables or plastic pipes.
• Avoid quoting regulation numbers as legal advice; cite as public wiring practice context only.

Practical Next Step

Use the checklist in order. If the manual, care label, appliance guidance or safety source says no, stop there; if it says yes, test the least risky small area or setup before scaling up.
