What CHAS asks a contractor for

CHAS Standard

The SSIP safety assessment, with your insurance.

CHAS Standard asks for 21 things. RAMS AI keeps or writes 15 of them for you as you work.

Kept for you as you work (14)

Health and safety policy, signed within the last 12 months

Signed by the person at the top, saying who is responsible for what. Reviewed every year.

How the firm manages safety: the arrangements

Inside the policy: risk assessment, training, COSHH, PPE, first aid, accidents, fire and the rest.

Drugs and alcohol

A section of the health and safety policy.

Competent health and safety advice

Who the firm goes to, named in the policy.

Training, toolbox talks and inductions, with records

The talks given and the inductions done, each with who signed.

Site checks, and what changed after them

Walk-rounds on jobs, and the policy's yearly review.

Talking to the workforce about safety

Toolbox talks, and the policy's section on it.

Accident and near-miss records

Incident reports, and the policy's section on RIDDOR. Schemes ask for three years' figures.

Checking the subcontractors you bring in

The policy says how they are checked; their cards on file show it was done.

Risk assessments and method statements from the last 12 months

Site-specific RAMS, signed off on real jobs.

COSHH assessments

Only if the firm uses something that could harm health: one for each substance.

Working with the principal contractor and other trades

Handover records with the site manager's Seen on them.

Welfare on site

A section of the health and safety policy (CDM Schedule 2).

A construction phase plan where the firm is the only contractor

Only for jobs done direct for a client.

Written for you from a few answers (1)

Your duties under CDM 2015

Which role the firm takes and how it meets it: the CDM section of the health and safety policy.

Yours to supply: snap it once, and we remind you before it runs out (6)

Everyone's cards and tickets, in date

CSCS and trade cards on file for each person, with their end dates.

Enforcement action in the last five years

You declare it on the scheme's own form: any HSE notices or prosecutions.

Plant and kit with inspection records

The kit list, with each item's last inspection and the next due.

Employers' liability insurance

£5 million minimum, the law if the firm employs anyone. The certificate, with its end date.

Public liability insurance

The certificate, with its end date. Every scheme asks.

Professional indemnity insurance

Only if the firm designs. Most subcontractors don't need it.
