The Work at Height Regulations 2005 explained for small contractors

What counts as work at height and why it matters

If you can fall and get hurt, you are working at height. That includes a single step onto a mezz floor with no guard, standing on a flat roof to reseal a pipe, or up a podium fixing a door closer in a busy corridor. There is no magic 2 metre threshold. The Work at Height Regulations 2005 say the duties bite wherever there is a risk of a fall liable to cause personal injury. HSE’s leaflet INDG401 spells this out in plain language, which is why the old 2 metre myth needs binning.

Falls from height still kill tradespeople, and not just on big commercial frames. Small jobs go wrong on wet Tuesdays when the tower is short a toe board, the slab is slick with slurry, and you are reaching over a void to finish a cut. The duties sit with the employer or the self‑employed person controlling the work. If it is your gang, your job or your RAMS, you wear the responsibility. The regulations are not there to stop work. They are there so you do it without anyone going through a ceiling.

If you need a deeper checklist for your paperwork, our Work at Height RAMS Guide for UK Contractors goes into specific hazards and controls.

Plan it and supervise it, then work the plan

Regulation 4 of the Work at Height Regulations 2005 says work at height must be properly planned, appropriately supervised and carried out in a safe manner. That starts before you load the van. Think access and egress, the surface you will stand on, the kit you need, the weather, nearby traffic or plant, services overhead, fragile roofs, public interface and an emergency plan. Sketch it out while the smell of cut cement board is still in your nose from the survey, and write it into the method so nobody is guessing on site.

Supervision does not mean a guy in a hi‑vis pointing at things. It means someone competent checking the plan is being followed, adjusting when reality bites and stopping the work if the control is not there. If a transom is part‑loaded or a guardrail has been off and not refitted, the job pauses. If wind picks up on a MEWP, you come down and wait. Reg 4 expects that level of judgement. HSE INDG401 backs this, saying planning, organisation and method must be suitable for the job and the actual conditions.

Competence in plain terms

Regulation 5 says those involved in work at height must be competent, or if being trained, supervised by a competent person. Competence is not a card on its own. It is the right training, the right experience, and the right attitude. If your improvised fix for a missing brick guard is a ratchet strap and a prayer, you are not competent for that setup. If you know when to get a tower in instead of overreaching a ladder, you are getting there.

You show competence by the decisions you make and the records you keep. Inductions that actually mention live edges on level 5, toolbox talks that cover the day’s lift path, and a lead hand who can spot when a roof light is hiding under chippings. If you are using specialist kit like a MEWP, tower or safety nets, make sure the operator or installer has the right recognised training and is familiar with that exact model. Regulation 5 expects that the planner, supervisor and worker all meet that bar for their bit of the job.

Use the hierarchy: avoid, prevent, then mitigate

Regulation 6 sets the order. First, avoid work at height if you can. That might mean doing as much as possible from the ground. Fit windows from inside out on low floors, use extendable tools for signage, pre‑assemble cladding cassettes at ground where the rivet gun and sealant are safer to handle. If you can bring the work down, do it. INDG401 reinforces this point with simple examples.

Second, prevent a fall. If you must go up, use a safe working platform with collective protection. That is guardrails, toe boards, and secure decking on a tower or scaffold built to a recognised standard, or a MEWP with properly closed gates and the right outreach for the spot. On roofs, keep people behind a parapet or temporary edge protection. Seal off fragile areas with covers that are secured and marked, not a bit of ply flapping around in the wind.

Third, mitigate the consequences. If you cannot remove the fall risk or guard it off, use personal fall protection. That is restraint to stop you reaching the edge, or fall arrest with a proper anchor and a rescue plan. Use lifelines by competent installers and lanyards suitable for the job. Mitigation is the last resort in reg 6 for a reason. Relying on a harness because the scaffold is missing a lift is back to front and will not wash if anything goes wrong.

Picking kit that suits the job

Ladders are not banned. HSE INDG401 is clear that ladders and stepladders can be used for low risk, short duration tasks where it is not reasonably practicable to use something safer. Short duration means it really is a quick job, not a full morning. The ladder must be in good condition, on firm ground, and used by someone who knows what good looks like. If you are reaching, carrying weight, or the surface is greasy, get a podium, tower or MEWP in instead.

Towers and scaffolds give collective protection when built right. Make sure they are erected by competent people following manufacturer instructions or current industry guidance, and do not move a mobile tower with someone on it. On bigger runs, a tied scaffold with proper edge protection and brick guards is often quicker than juggling ladders all day. For MEWPs, focus on ground bearing, weather, reach and exclusion zones. A scissor on a slab on a wet multi‑storey can drift, so chock and plan your route with a spotter if needed.

Whatever you pick, match it to the task and location. Busy live sites need barriers and sign‑off so a member of the public does not wander under your deck. Confined plant rooms suit podiums and small towers. Roof works need edge protection or a restraint system and good housekeeping so offcuts and screw boxes do not become trip points near an edge. Your method should say what you chose and why, because reg 6 expects you to justify that choice against safer options.

Inspections, records and fixing defects

Regulation 12 of the Work at Height Regulations 2005 requires inspection of work equipment and places of work at height. In practice, that means pre‑use checks by the user, formal inspections at suitable intervals by a competent person, and written records. For scaffolds, reg 12 and Schedule 7 require inspections before first use, at least every 7 days, and after events likely to affect stability, like high winds or unauthorised alterations. If you find a defect that creates a risk, do not use it until fixed.

Towers and podiums need recorded inspections at suitable intervals given the environment and usage. MEWPs should have daily pre‑use checks and suitable documented maintenance, with the platform gates and emergency descent tested before you go up. Harnesses and lanyards used for fall protection need periodic detailed inspections by a competent person to a schedule set by the manufacturer, and pre‑use checks by the wearer. All of this sits under reg 12 and good practice sits alongside it. HSE INDG401 highlights the need for inspection and record keeping.

Make it easy to do the right thing. Tag systems on towers and scaffolds help show status. A simple weekly form on the clipboard in the container works if it is filled in properly. If a guardrail comes off for materials and the crew forgets to refit it, that is a notifiable defect to the supervisor and the platform is out of service. If it is your site, you own that decision. For the detail on weekly scaffold examinations, see Scaffold inspections: how often, who can do them, what to record.

Questions we get asked

Is there a 2 metre rule for working at height?

No. The Work at Height Regulations 2005 apply wherever a person could fall and be injured, with no minimum height. HSE’s leaflet INDG401 confirms this and kills the old 2 metre myth. If you can fall and get hurt, the duties apply.

Can I still use a ladder for quick jobs?

Yes, if it is low risk and short duration, and if a safer option is not reasonably practicable. HSE INDG401 says ladders and stepladders are acceptable for short, simple tasks. Use a competent person, a sound ladder, firm footing and avoid overreaching. If in doubt, use a podium or tower.

What does ‘competent’ mean under the regs?

Regulation 5 says those doing or planning the work at height must be competent, or supervised if training. In practice, that means the right training, knowledge and experience for the task and the equipment, and the judgement to stop if conditions change.

How often must scaffolds be inspected?

Scaffolds must be inspected before first use, at intervals not exceeding 7 days, and after events likely to affect stability, such as high winds or unauthorised changes. This comes from the Work at Height Regulations 2005 reg 12 and Schedule 7.

Do I need a rescue plan if using a harness?

Yes. Planning for emergencies is part of reg 4 on planning and organisation. If you use fall arrest, you must plan how you will rescue a suspended person quickly and safely. Do not rely on calling 999 and hoping for the best.

What paperwork do I need for a small job at height?

You need a plan and risk assessment with the hierarchy in mind, competent people on the task, and inspection records for the equipment and platform as required by reg 12. HSE INDG401 summarises the duties. Keep it simple but specific to the job and conditions.

The short version

The Work at Height Regulations 2005 apply wherever a fall could injure. There is no 2 metre threshold. Plan and supervise the job under reg 4, use competent people under reg 5, follow the reg 6 hierarchy of avoid, prevent, then mitigate, and inspect platforms and equipment under reg 12 with records kept.

Pick kit that suits the task and location, control fragile surfaces, and plan a rescue if you use fall arrest. Small jobs go wrong when the basics slip, like a missing guardrail or a slick slab. Keep it practical, write it down, and work the plan so everyone goes home.
