Pause before the risk
Good DIY knows its limits.
No online guide can assess every site. Work involving live services, gas, structure, heights, hazardous materials or regulated systems may require a licensed professional.
01
Electricity and gas
Do not open, alter or test live or regulated systems unless you are qualified and legally permitted to do so.
02
Heights and roofs
Falls are a major risk. Avoid wet, steep, brittle or unfamiliar roofs and use professional access where needed.
03
Structure and excavation
Unexpected movement, cracking, unstable soil, retaining structures and load-bearing changes need competent assessment.
04
Hazardous materials
Older homes may contain asbestos, lead paint or other hazards. Do not disturb suspect material before proper identification.
