Top tips

Hiring a scaffolder, without the regret.

Four moves that separate a smooth job from a nightmare.

CISRS-card holders only.

Every scaffolder on site needs a CISRS card. No card = no insurance cover if there's an accident. Insist on seeing them.

Get the design drawing.

Any scaffold over 38m, or non-standard, needs a TG20 design or bespoke drawing. Without it, the scaffold isn't compliant — and your project isn't either.

Daily inspection certificate.

Working scaffolds need a SG4-compliant inspection at handover and every 7 days. Insist on the signed inspection paperwork.

Check pavement licence.

Anything on pavement or road needs a council pavement licence (£70–£300). Scaffolder usually arranges; check it's in place before they start.
