What does RAMS stand for — and why it matters on UK sites
What does RAMS stand for is a question every construction worker, tradesperson, and contractor should be able to answer confidently. RAMS stands for Risk Assessment and Method Statement. Together, these two documents often form the core health and safety record for construction, trade, and maintenance jobs in the UK. On many projects, principal contractors, clients, or site managers will ask to review RAMS before work starts.
But RAMS is frequently misunderstood. People treat it as a bureaucratic box-ticking exercise — something to be completed, filed, and forgotten. When RAMS is done properly, it's the most practical tool for keeping workers safe on site. The process of walking through each task systematically, identifying hazards, deciding how to control them, and describing the work sequence frequently surfaces dangers that would otherwise have been missed until they caused harm. When RAMS is done poorly, it's a liability — a document that looks compliant but provides no real protection.
The two documents that make up RAMS
The Risk Assessment — identifying and managing hazards
A risk assessment is an analytical document. Its job is to identify everything that could go wrong during the work and to document the controls needed to manage those hazards. It follows the HSE's five-step framework: identify hazards, decide who might be harmed, evaluate risks and decide on precautions, record findings, and review and update.
For each hazard, the risk assessment must show: what the hazard is — described specifically, not generically; who is at risk — operatives, other trades, members of the public, and clients; how likely it is to cause harm — Likelihood, rated 1 to 5; how serious the harm could be — Severity, rated 1 to 5; the Likelihood × Severity = Risk Rating — both initial (before controls) and residual (after controls); and the controls applied, at each level of the hierarchy: eliminate, substitute, isolate, engineering controls, administrative controls, PPE as last resort.
The 5×5 Risk Rating Matrix
The industry-standard approach uses a 5×5 matrix — Likelihood multiplied by Severity — to produce a Risk Rating from 1 to 25. Likelihood 1 means the event is almost never expected; Likelihood 5 means it is almost certain. Severity 1 means negligible consequences such as a minor bruise; Severity 5 means catastrophic consequences including multiple fatalities.
The resulting classifications are: 1-4 is Low (acceptable with existing controls); 5-9 is Medium (specific controls must be in place); 10-14 is High (additional controls required before work proceeds); 15-25 is Very High (immediate action required before work begins). A professional RAMS document shows both the initial risk rating — before any controls — and the residual rating after specified controls are in place. Showing only the residual rating without working is incomplete and will be challenged by principal contractors.
The Method Statement — planning the work
A method statement is a planning and communication document. It describes exactly how the work will be carried out safely, step by step. Where the risk assessment answers "what can go wrong?", the method statement answers "here is exactly what we will do, in what order, using what equipment, with what precautions."
A method statement is not organised by hazard — it's organised by work sequence. It describes the steps of the work from start to finish, and for each step explains what is happening, what hazards arise, and what controls apply. Every significant hazard in the risk assessment must be reflected in the method statement, and vice versa — if one changes, the other must be updated to match. The method statement should be written in plain English that anyone can understand, not just experienced tradespeople.
What must be included in a complete RAMS document
A complete RAMS document should contain certain standard sections. These are commonly expected by principal contractors and are useful when demonstrating that the work has been properly planned.
The project and task description must be specific — not "electrical installation" but "first fix electrical installation in a new-build three-bedroom detached house, including cable routing via ceiling voids and timber stud walls, with dry liner contractors and first-fix plumbers on site simultaneously." Generic task descriptions are the most common and most damning mistake in RAMS writing. They tell the principal contractor that the RAMS was written without visiting the site or planning the specific work.
The personnel and competency section should name who will carry out the work and reference their relevant qualifications — ECS cards, CSCS cards, Gas Safe registration, NVQ qualifications — and confirm they've been briefed on the RAMS. Where competence needs to be demonstrated, naming the relevant people and qualifications makes the document easier to review.
The hazard identification section must be comprehensive. For electrical work, this means including electric shock from live conductors, arc flash from switching operations, cable strikes during first fix, manual handling of heavy distribution boards, dust from drilling and chasing, asbestos in properties built before 2000, working at height accessing ceiling voids, and interaction hazards from other trades working simultaneously. Hazards not identified cannot be adequately controlled.
The risk assessment section uses the 5×5 matrix to rate each identified hazard. Control measures must be specific and verifiable — not vague statements like "take care." "Isolate circuit at consumer unit, apply personal lock-off device, verify dead with calibrated two-pole voltage indicator meeting GS38 requirements" is a control measure. "Be careful of live cables" is not.
How RAMS fits into UK legal duties on construction sites
The legal requirement for risk assessments arises from the Management of Health and Safety at Work Regulations 1999, which requires every employer and self-employed person to assess the risks of their work activities and record significant findings. Method statements are commonly used to evidence how work will be planned and controlled under CDM 2015 and project-specific site rules, especially where a principal contractor is reviewing contractor documentation.
The Health and Safety at Work etc. Act 1974 creates the overarching duty for employers to ensure, so far as is reasonably practicable, the health, safety, and welfare of everyone affected by their work. This is the foundation of UK health and safety law. Failing to carry out adequate risk assessments — or failing to act on the findings — can result in HSE enforcement action, prosecution, and substantial fines or imprisonment in serious cases.
In addition to the general requirement, specific regulations impose further assessment, control, and planning duties for particular hazard categories: the Manual Handling Operations Regulations 1992, COSHH Regulations 2002, the Work at Height Regulations 2005, and the Personal Protective Equipment at Work Regulations 2022. A complete RAMS document should reflect the hazard categories that are actually relevant to the work.
In practice, many principal contractors on UK construction projects will ask to see RAMS before allowing a contractor to start work. Understanding what RAMS means and having a site-specific set ready puts you in a much stronger position when those documents are requested.
The most common RAMS mistakes that get documents rejected
Principal contractors who review RAMS submissions regularly see the same mistakes. These are not just technical deficiencies — they reveal that the contractor has not actually planned the work.
Generic content
A RAMS that reads the same for every job — "ensure safe working practices," "wear appropriate PPE," "be aware of hazards" — is not a RAMS document. It's a statement of intent that demonstrates no actual thought about the specific work. If your RAMS could have been written by someone who has never seen your site, it is not good enough.
Vague control measures
"Wear appropriate PPE" does not specify what PPE, at what standard, for which hazard. A proper control measure is precise: "FFP3 respirator (EN 149) for all dust-generating operations including drilling and chasing in areas where crystalline silica exposure is possible," or "safety footwear (EN ISO 20345 S3 SRC) worn at all times on site."
Risk ratings not shown
A risk assessment that says "medium risk" or "high risk" without showing the Likelihood × Severity equation is an opinion, not an analysis. The principal contractor cannot verify whether the rating is correct, consistent, or proportionate. Always show the full calculation — initial and residual ratings with the controls that justify each reduction.
PPE as the primary control
Listing PPE as the first line of defence for every hazard tells the reviewer that the writer does not understand the hierarchy of risk controls. PPE is the last resort in the hierarchy — Elimination, Substitution, Engineering Controls, Administrative Controls, then PPE. If your only control for electric shock is "wear insulating gloves," you have skipped the more effective controls: dead working, battery-powered tools, and lock-off procedures.
Risk assessment and method statement that do not connect
Every hazard in the risk assessment must appear in the method statement, and every method step that introduces a hazard must appear in the risk assessment. A RAMS where the two sections are clearly independent documents stapled together is a RAMS that was assembled, not written.
How to write a RAMS document efficiently
Writing RAMS from a blank page every time is error-prone. The practical approach is to start with a task-specific template, then customise it thoroughly for each specific job. This ensures no significant hazards are missed and the structure is consistent and recognisable.
First, describe the job specifically — not "electrical work" but the exact type of work, in the exact environment, using the exact materials and equipment, with the exact other trades present. Second, identify hazards systematically through each stage — preparation, access, the work itself, testing, and making good. Third, rate each risk using the 5×5 matrix, showing initial and residual ratings and applying the hierarchy of controls. Fourth, write the method statement as a coherent story — the complete sequence of work from start to finish, including access, the work itself, testing, making good, and emergency procedures. Fifth, sign it off. The RAMS must be signed by a competent person with the qualifications, experience, and authority to take responsibility for the safety of the work. Workers must also sign to confirm they've read, understood, and will follow the RAMS.
Who must write the RAMS and when it must be reviewed
Under CDM 2015, competence is demonstrated through skills, knowledge, experience, and organisational capability. A contractor with appropriate qualifications and a track record of safe working is competent to write a risk assessment for their own work. The method statement should be prepared by someone who understands the work intimately — typically a supervisor or senior operative — and reviewed by a manager or safety professional.
A RAMS is not a one-time document. It must be reviewed and updated whenever the work method changes, site conditions change, a near miss or incident occurs, the project moves to a different phase, or — on longer projects — at regular intervals of at least monthly. The version control record must show when it was last reviewed, what changed, and who approved the updated version.
Digital RAMS vs paper RAMS
The transition from paper to digital RAMS is well underway in UK construction. Principal contractors increasingly accept PDFs with digital signatures and version-controlled documents showing amendment history. The legal requirements for RAMS content are the same whether output is paper or digital — all mandatory sections, risk ratings, hierarchy-compliant controls, and competence evidence must still be included. A digital signature is legally acceptable under the Electronic Communications Act 2000, and HSE and courts accept digital RAMS as readily as paper in investigations.
The practical advantage of digital RAMS is version control. A RAMS revised because the work method or site conditions changed is clearly marked with the date and reason for revision. A paper RAMS with hand corrections is ambiguous: was the correction made before the work, or after? A digital RAMS with version history answers that question more clearly.
How long should RAMS be kept?
How long RAMS should be kept depends on the work, the records involved, and your legal or contractual obligations. Many businesses keep RAMS for at least three years because personal injury limitation periods are a common benchmark, while some related records — such as COSHH health surveillance records — may need to be kept for far longer.
If a serious incident is investigated, missing RAMS records can make it much harder to show that risks were considered, controls were in place, and the work was being managed as intended. Keeping clear records is usually far safer than relying on memory after the event.
