What is a risk assessment in UK construction?

A risk assessment is a legal requirement where employers identify workplace hazards, evaluate who might be harmed and how seriously, and record the control measures needed to reduce risk to an acceptable level. In UK construction, this must be done before work begins and reviewed regularly.

Risk Assessment — Definition

A risk assessment is the process of identifying hazards in a workplace, evaluating the likelihood and severity of harm they could cause, and determining appropriate control measures. In UK law, it's a duty under the Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999.

Risk Assessments Are Required — But Often Done Poorly

Many construction professionals treat risk assessments as paperwork to tick a box. Generic templates get copied between projects with minimal changes. Hazards specific to the actual site get missed. The result: documents that satisfy nobody — not the HSE, not the principal contractor, and certainly not the workers they're supposed to protect. Understanding the complete guide to RAMS in the UK helps frame why proper documentation matters.

The Health and Safety Executive states: 'A risk assessment is not about creating huge amounts of paperwork, but rather about identifying sensible measures to control the risks in your workplace.'

How Riskora Helps

A good risk assessment doesn't have to be long or complex. It needs to be specific to the work being done, on the site where it's happening, with the people who'll actually be doing it. Riskora's guided builder helps you create structured risk assessments with pre-loaded hazard libraries — ensuring you cover the right risks without writing from scratch. You can also use our standalone risk assessment builder or method statement tool.

Who it's for

  • Construction site work
  • Demolition and excavation
  • Working at height
  • Manual handling activities
  • Confined space entry
  • Hot works and welding

Risk Assessment Legal Requirements (UK)

The legal framework behind risk assessments in the UK — what the law requires and what 'suitable and sufficient' means.

Is a risk assessment a legal requirement in the UK?

Yes. Under the Management of Health and Safety at Work Regulations 1999, all employers and self-employed persons must carry out risk assessments. If you employ five or more people, the significant findings must be recorded in writing.

What are the 5 steps of risk assessment?

The HSE's five steps are: 1) Identify the hazards, 2) Decide who might be harmed and how, 3) Evaluate the risks and decide on precautions, 4) Record your significant findings, 5) Review your assessment and update if necessary.

Who is responsible for risk assessments on a construction site?

Under CDM 2015, the principal contractor is responsible for managing risk on site. However, every employer and self-employed worker has a duty to assess risks for their own activities. Subcontractors must produce risk assessments for their specific work.

Key Risks and Considerations

  • •Failing to identify site-specific hazards
  • •Using generic assessments without review
  • •Not consulting workers during the process
  • •Failing to review after incidents or changes
  • •Not recording significant findings

Inside the document

What your RAMS actually contains

Riskora builds a structured, client-facing document — not a generic AI paragraph. Every section is shaped around your job, your site and your team.

  • Hazards

    Task-specific hazards for the job, captured row by row — not a generic list pulled from an old RAMS.

  • Controls

    Control measures mapped to each hazard with residual risk scoring after controls are applied.

  • PPE

    PPE requirements tied to the activity and site, ready to brief to the team.

  • Method steps

    Step-by-step method statement structured around how the work is actually sequenced on site.

  • Emergency arrangements

    First aid, rescue plan, emergency contacts and site-specific escalation routes.

  • COSHH prompts

    Substance prompts when the work involves chemicals, dusts, fumes or sealants — flagged early, not missed at review.

  • Sign-off

    Operative sign-off captured against the document — names, dates and acknowledgement of the brief.

  • Version history

    Every change tracked so you can show what was issued, when, and which version the team signed.

  • Approval status

    Clear approval state on every document — draft, in review, approved, issued — visible across the team.

  • Audit trail

    Who created it, who reviewed it, who signed it. A complete trail you can hand to a principal contractor or auditor.

Before & after

From copied-and-pasted to site-specific

The reason RAMS get rejected is rarely the format — it's that the document is obviously generic. Riskora rebuilds it around this job, this site and this task.

Before

Generic template copied from an old job.

  • • Hazards and controls that don't match this site or task.
  • • Method steps written for a different sequence of work.
  • • No emergency arrangements specific to the location.
  • • Client flags it as generic and asks for a rewrite.
After

Site-specific document structured around this job, site and task.

  • • Hazards captured from the actual scope you pasted in.
  • • Method steps sequenced for how the work runs on site.
  • • Emergency arrangements and rescue plan tied to the location.
  • • Approved internally, briefed to the team, signed off and stored.

Frequently Asked Questions

Risk assessments should be reviewed whenever there are significant changes to the work, after incidents or near-misses, when new information about hazards becomes available, or at least annually as good practice.

Yes, if you are competent to do so. The HSE defines competence as having sufficient training, experience, knowledge, and other qualities. For high-risk activities, you may need specialist support.

It's the wording from the Management of Health and Safety at Work Regulations 1999. In practice it means the assessment identifies the significant hazards, evaluates who could be harmed, considers existing controls, and is proportionate to the risk — not generic, not exhaustive, but enough to actually inform safer work.

Not always. If the work, site conditions and people are genuinely the same as a previous job, you can reuse a risk assessment — but you must review it and confirm nothing has changed. As soon as the site, scope or team changes, it needs revisiting.
