UK site rules explained: the words you will hear and what they mean for you
Twenty-five terms a new worker meets in the first month on a UK site, each in two to four plain sentences: what it is, which law or scheme sits behind it, and what you are expected to do. Ending with who is allowed to sign what.
Checked October 2026 against HSE, CITB, CSCS and GOV.UK. General information, not legal advice.
- CSCS card: £36, needs a CITB test pass from the last 2 years
- CITB HS&E test: 50 questions, 45 minutes, £23.50
- RAMS: read it, understand it, then sign it
- Working at height: the biggest killer on UK sites
- Hot works and confined spaces need a permit
- Competent person: training, experience and knowledge, not a job title
Cards and tests
The Construction Skills Certification Scheme card proves you hold the training and qualification for your trade. It is not a legal requirement, but almost every main contractor makes it a site rule, so in practice no card means no work. You apply online for £36 and need a CITB Health, Safety and Environment test pass from the last two years. Guides: CSCS cards and your first card.
The "touch screen test": 50 multiple-choice and behavioural questions in 45 minutes at a test centre, costing £23.50 from April 2026. Operatives, Specialists and Managers versions exist. A pass is valid for two years for the purpose of applying for a card. How to pass first time, with free practice.
Green is the Labourer card (Level 1 Award in Health and Safety in a Construction Environment). Blue is Skilled Worker (NVQ Level 2 in your trade). Gold is Advanced Craft or Supervisor (NVQ Level 3). Black is Manager. Red cards are temporary, for apprentices, trainees and experienced workers finishing an NVQ. All card types explained.
Separate cards for plant and access equipment. CPCS and NPORS cover plant such as excavators, dumpers and telehandlers; PASMA covers mobile scaffold towers; IPAF covers mobile elevating work platforms (cherry pickers, scissor lifts). You cannot operate these on a UK site without the matching card, whatever your experience at home. IPAF or PASMA: which one you need · CPCS cards.
Before you start, the firm must check you are allowed to work in the UK. For most non-British workers that means a free share code from GOV.UK, valid 90 days, which the firm checks online. From 1 October 2026 the duty extends to self-employed subcontractors engaged by a contractor, so expect every main contractor and agency to ask. How it works.
Before you start a task
The briefing every person receives before their first shift on a site: rules, hazards, welfare, emergency arrangements, who to report to. You show your CSCS card and ID, fill in a form and sign. No induction, no work, and you may have to repeat it on a new site even for the same firm.
Risk Assessment and Method Statement: one document that says what could go wrong on a task, what controls reduce the risk, and the step-by-step method for doing it. You are briefed on it and sign to confirm. If the real work differs from the RAMS, stop and raise it. Small firms can create one with the free Graftum RAMS generator.
The legal part of RAMS. Every employer must assess the risks of its work (Management of Health and Safety at Work Regulations 1999) and, with five or more employees, write down the significant findings. It should name the hazard, who could be harmed, and the controls. A risk assessment nobody on site has read is paperwork, not safety.
The practical part of RAMS: the sequence of work, the equipment, who does what, the permits needed. Not a specific legal requirement on its own, but main contractors demand one for every subcontracted task because it is how they check the job has been thought through.
A short safety briefing, 10 to 15 minutes, on one topic, usually at the start of a shift. You sign the attendance sheet. Main contractors use frequency of toolbox talks as evidence of a safety culture; keep your copy of anything you sign if you can.
A formal written authorisation for high-risk tasks: hot works, confined spaces, work near live services, excavations, isolations of electrical or gas systems. It states the task, the precautions, the time window and the person authorising it. Without a live permit you do not start, and when the permit expires you stop.
A permit for any task producing flame, sparks or heat: welding, grinding, torch-on roofing, soldering. It usually requires removal of combustibles, a fire extinguisher at the work face and a fire watch after finishing (commonly 60 minutes; the permit says). Hot works are a leading cause of fires on sites and insurers demand the permit system.
On the tools
Personal protective equipment: hard hat, hi-vis, safety boots, gloves and glasses as the standard five, plus hearing protection, dust masks (FFP3), harnesses for specific tasks. Employers must provide what the job needs free of charge to employees and workers (PPE at Work Regulations 1992, extended in 2022). PPE is the last line of defence, not a substitute for removing the hazard.
Any work where a person could fall a distance liable to cause injury, including below ground level. The Work at Height Regulations 2005 require the employer to avoid it where possible, prevent falls where it cannot be avoided (guard rails, platforms) and minimise the consequences otherwise (nets, harnesses). Falls from height are the biggest single cause of death on UK sites. Ladders are for short, low-risk tasks only.
The card at each scaffold access point. Green means the scaffold has been inspected by a competent person and is safe to use; the inspection must be repeated at least every 7 days and after any alteration or bad weather. Red or no tag means do not use. Never alter a scaffold yourself: that is for a CISRS-carded scaffolder.
An exclusion zone is a taped or barriered area you may not enter: under a load, around plant, near an open excavation. A banksman or traffic marshal directs vehicles and plant and controls who enters the zone; a slinger-signaller does the same for crane lifts. If they signal you to stop, you stop.
Control of Substances Hazardous to Health Regulations 2002. On site this is mainly dust (especially silica from cutting concrete, stone and blocks), cement, solvents and fumes. The employer must assess exposure and control it: water suppression, on-tool extraction, then RPE. Long-term lung disease kills many more construction workers than falls do.
Lifting, carrying, pushing and pulling by hand. The Manual Handling Operations Regulations 1992 require employers to avoid hazardous lifts, assess those that remain and reduce the risk. There is no legal maximum weight; HSE's guideline figures (about 25 kg at waist height for men, 16 kg for women, less when lifting away from the body) are triggers for assessment, not permissions.
Training required under the Control of Asbestos Regulations 2012 for anyone whose work could disturb asbestos, which includes most trades working in buildings built or refurbished before 2000. Awareness training teaches you to recognise, avoid and report suspected asbestos; it does not allow you to work on it. If you find material you suspect, stop, do not disturb it, tell the supervisor.
Sealing the gaps where pipes, cables and ducts pass through fire-rated walls and floors so that fire and smoke cannot spread between compartments. Only trained installers may do it, usually with third-party certification, and every penetration is recorded and photographed. Drilling through a fire wall and leaving it open is one of the fastest ways to be removed from a site since the Building Safety Act.
An enclosed space where there is a reasonably foreseeable risk of serious injury from gases, lack of oxygen, flooding or heat: tanks, manholes, deep excavations, some risers and ducts. The Confined Spaces Regulations 1997 require avoiding entry where possible, and otherwise a safe system of work with a permit, gas monitoring and rescue arrangements. Never enter one to rescue a colleague without the equipment.
People and paperwork
HSE's definition: someone with sufficient training and experience or knowledge and other qualities to do the task properly. It is not a job title or a card; it is a judgement the employer must make about each person for each task, and must be able to justify. When a site asks "are you competent to do this?" the honest answer is sometimes "not without supervision".
The Construction (Design and Management) Regulations 2015 set out who is responsible for health and safety on a project: the client, the principal designer and the principal contractor. The principal contractor runs the site, writes the construction phase plan, controls access and provides welfare. Larger projects are notified to HSE on form F10. You will hear "the PC" meaning the firm in charge.
The site manager runs the site day to day; the supervisor leads a trade gang. SMSTS (5 days) and SSSTS (2 days) are the CITB courses most main contractors require for those roles. A gold or black CSCS card plus the course is the usual combination. Neither makes a person your employer; your firm pays you. SSSTS or SMSTS: which course you need.
What the site must provide for workers under CDM 2015 Schedule 2: toilets, washing facilities with hot and cold water, drinking water, somewhere to change and dry clothes, and a rest area where you can eat. If a site has none of this, the principal contractor is in breach, and HSE treats it seriously.
The daily register of who is on site, kept for fire evacuation roll calls and as the record of attendance. Sign yourself in and out every day. It is also the first evidence anyone looks at in a dispute about hours worked, so a photo of the sheet protects you.
The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 require the employer to report deaths, specified serious injuries, injuries causing more than 7 days off work and certain dangerous occurrences to HSE. A near miss is an incident that could have caused harm but did not; sites want them reported so the next one is prevented. Reporting is never grassing.
Every site needs first-aid arrangements. A first aider has completed an approved course (First Aid at Work, 3 days, or Emergency First Aid at Work, 1 day). An appointed person looks after the first-aid kit and calls the emergency services. Their names and location are told to you at induction; write them down.
Who can sign what
A lot of site paperwork is about signatures, and signing something you are not entitled to sign can cost you your card. The common ones:
| Document | Who signs it | What your signature means |
|---|---|---|
| RAMS briefing sheet | You, after being briefed | You have read and understood the RAMS and will follow it. Do not sign one you have not understood. |
| Toolbox talk register | You, as an attendee | You attended. It also proves you were on site that day. |
| Timesheet or day sheet | You record; your supervisor approves | Your hours as worked. The supervisor's signature authorises payment; keep a copy before handing it in. |
| Permit to work, hot works permit | The authorised person (usually site management), plus the person doing the work | The authoriser confirms precautions are in place; you confirm you will keep to them and stop when it expires. |
| Scaffold tag / inspection | A competent scaffold inspector (CISRS) | The scaffold was inspected and is safe to use. You never sign or alter a tag. |
| Electrical installation certificates | A qualified electrician, usually registered with a competent person scheme (NICEIC, NAPIT and others) | The installation was designed, installed and tested to BS 7671. A labourer or mate cannot sign. |
| Gas work | A Gas Safe registered engineer only | It is illegal for anyone else to work on gas appliances or pipework. |
| Fire-stopping records | The trained installer, often with third-party certification | Each penetration was sealed with the specified product. Photographed and logged. |
| Plant daily checks | The operator holding the plant card | The machine was inspected before use. You do not sign for a machine you are not carded to drive. |
| Accident book / RIDDOR | The injured person or a witness; the employer reports to HSE | A factual record. You have the right to see what is written about your accident. |

If a rule is being broken
Rules on a UK site are written in the past tense: each one exists because someone was killed or hurt. If you see one being ignored, the sequence is: stop, move away from the danger, tell the supervisor, then the site manager, and if nothing changes report it to HSE through the concerns form on hse.gov.uk, anonymously if you prefer. Employees and workers are protected by law from being dismissed or treated badly for raising a genuine safety concern.
The same records that keep you safe also protect your pay: signed RAMS sheets, toolbox registers and sign-in sheets prove where you were and when. Our guides Your first week on site and Not paid: what to do show how to use them.
Questions workers ask
Is a CSCS card a legal requirement?
No law requires it, but nearly every main contractor makes it a condition of entry, so in practice you need one. The right card for your trade, with a CITB test pass from the last two years, costs £36 to apply for.
How often do I need to retake the CITB test?
A pass is valid for two years for the purpose of applying for or renewing a CSCS card. If your card renewal falls more than two years after your last pass, you sit the test again (£23.50).
Do I have to sign the RAMS?
You are expected to, after being briefed, because it records that you understand how the task is to be done. Do not sign a RAMS you have not understood: ask for it to be explained first. Refusing to sign something you do not understand is reasonable; signing it and working differently is not.
Who pays for my PPE?
If you are an employee or a worker (including through an agency or umbrella), your employer must provide the PPE the job requires free of charge. Genuinely self-employed workers usually bring their own basic kit and the firm supplies task-specific items. Agree it before you start.
What does "competent person" actually mean?
HSE defines it as someone with sufficient training and experience or knowledge and other qualities to carry out the task properly. It is a judgement about the person and the task, not a certificate. Cards and courses are evidence of competence, not the thing itself.
Can I work at height from a ladder?
Only for short-duration, low-risk tasks where a safer option is not reasonably practicable, with the ladder secured and three points of contact. For anything longer, the site should provide a tower, platform or scaffold. Falls from height are the leading cause of death on UK sites.
What do I do if I find something I think is asbestos?
Stop work immediately, do not disturb or move the material, keep others away and tell the supervisor. Asbestos awareness training lets you recognise and report it, not remove it. Licensed contractors handle removal.
What is RIDDOR and does it apply to me?
The regulations requiring employers to report serious workplace injuries, certain diseases and dangerous occurrences to HSE. The duty is on the employer or the person in control of the site, not on you, but you should report every accident and near miss so that it can be recorded.
