Working at Height Regulations Explained: There's No 2 Metre Rule

The working at height regulations are the Work at Height Regulations 2005. They came into force on 6 April 2005 and apply across Great Britain. They cover employers and anyone who controls work at height, from a contractor to a building owner. There's no minimum height. The rules apply wherever a fall could injure someone, even at ground level. And they set an order to follow. Avoid the work at height, prevent a fall, then minimise one.

So the first question on any job isn't how high it is. It's whether anyone needs to be up there at all. Falls from height killed 31 of the 126 workers who died in work accidents in Great Britain in 2025/26, more than any other cause, according to HSE's provisional figures. In construction, falls caused over half of all worker deaths across the last five years.

What is working at height?

HSE defines work at height as "work in any place where, if there were no precautions in place, a person could fall a distance liable to cause personal injury".

HSE's work at height FAQs add that it includes falling from an edge, through an opening or a fragile surface, and dropping from ground level into a hole. On site, that covers more than ladders and scaffolds.

• fixing a smoke detector from a stepladder
• laying felt on a flat roof
• setting out beside an open excavation
• walking past an unguarded stairwell opening on a new floor
• clearing a gutter next to fibre-cement roof sheets

Two things don't count. A slip or trip on the level isn't one, because you don't drop to a lower level. Nor is using a permanent staircase in a building.

There's no 2 metre rule

Plenty of people will tell you work at height starts at 2 metres. It doesn't. The legal definition sits in regulation 2 of the Work at Height Regulations 2005. It says "work in any place, including a place at or below ground level". No height appears anywhere in it.

You won't find a 2 metre rule in HSE's guidance either. HSE's definition turns on whether a fall could cause "personal injury", however short the drop.

The 2 metre figure has a history. The Construction (Health, Safety and Welfare) Regulations 1996 required guard-rails, toe-boards or barriers where someone could fall 2 metres or more. The 2005 regulations revoked that rule when they came in.

The number survives in one place. Under regulation 12(4), a construction working platform from which someone could fall 2 metres or more must have been inspected within the previous 7 days. It's an inspection rule only. It doesn't decide whether a job counts as work at height.

No minimum height doesn't mean a harness for every step. HSE says "there may be some low-risk situations where common sense tells you no particular precautions are necessary". Two minutes on a stepladder and a day on a sloping roof are both work at height. The precautions are nothing alike.

Avoid, prevent, minimise: the order the law sets

Regulation 6 sets three steps, in order. You only move on when the step before isn't reasonably practicable.

Avoid. Don't work at height if the job can be done safely another way. HSE's examples include using extendable tools from the ground and assembling edge protection at ground level before it goes up.

Prevent. If the work has to happen at height, stop a fall happening. First choice is an existing safe place, such as a flat roof with a permanent guard-rail. If there isn't one, use equipment such as a scaffold, a tower scaffold or a scissor lift.

Minimise. If a fall is still possible, cut how far someone would drop and how badly they'd be hurt. Safety nets or air bags rigged close under the work do that. So does a fall-arrest harness clipped to a high anchor point.

At every step, regulation 7 puts measures that protect everyone ahead of measures that protect one person. A guard-rail works whether or not anyone remembers to clip on. A harness only works if they do.

What employers must do

The duties sit on employers and on anyone who controls work at height. HSE names contractors, facilities managers and building owners who bring others in.

Duty	What it means on site	Regulation
Plan and supervise	Planning covers the right equipment and a plan for emergencies and rescue, and the work is supervised	4(1) and 4(2)
Watch the weather	Work only goes ahead when the weather doesn't put people at risk	4(3)
Use competent people	Only competent people plan, supervise or do the work, or trainees working under someone competent	5
Assess the risk	The measures come from a risk assessment under the Management Regulations	6(1)
Choose the right kit	Protection for everyone first, sized for the job and the loads	7
Inspect equipment	Inspect it after it's put up and, where conditions wear it, at suitable intervals and after anything that could affect its safety	12
Check the place	Check the surface, parapets and rails every time before the place is used	13

If a job can't tick every row, it isn't ready to start.

HSE describes a competent person as someone with the "skills, knowledge and experience" for the task. On rescue, it warns against relying entirely on the emergency services. The general duty to train staff has its own guide, health and safety training for employees.

Ladders are allowed, for the right job

Ladders aren't banned. Schedule 6 allows one when a risk assessment shows better equipment isn't justified, because the risk is low and the use is short, or because site features can't be changed.

HSE's ladder guidance says risk comes first, and short duration isn't the deciding factor. As a guide, if a job would keep you on a leaning ladder or stepladder for more than 30 minutes at a time, HSE recommends other equipment.

When a ladder is right, HSE's guidance comes down to a few habits.

• Check the stiles, feet, rungs and any locks at the start of the day and after anything changes. If something's wrong, don't use it, and tell whoever's in charge.
• Stand it on firm, level, clean ground, using levelling devices, not bricks.
• Secure it. Tie both stiles if you can. If not, use a stability device, then wedge it. Footing is the last resort.
• Set a leaning ladder at 1 in 4, one unit out for every four up.
• Keep your belt buckle inside the stiles, and stay off the top three rungs.
• Tie an access ladder and let it stick out at least 1 metre above where you step off.

On a stepladder, a brief two-handed job is allowed. HSE says two feet plus your body supported by the steps counts as three points of contact.

Picking the right ladder, pre-use checks and safe set-up are covered in Ladder Safety Awareness.

Fragile roofs and surfaces

A fragile surface is one that would fail under any reasonably foreseeable load. HSE's usual suspects include rooflights, fibre-cement sheets, corroded metal sheets, glass, rotted chipboard, and slates and tiles. Its construction guidance says to treat every roof as fragile until a competent person confirms it isn't.

Regulation 9 follows the same order as before. Keep people off and away from fragile surfaces where you can. Where you can't, provide platforms, coverings or guard-rails that take the load, and minimise any fall that's still possible. Put prominent warning notices at the approach, or make sure people know some other way.

Falling objects and danger areas

Regulation 10 deals with things that fall. Where it's needed to prevent injury, stop materials and objects falling. If you can't, stop anyone being struck. Nothing gets thrown or tipped from height where it could hurt someone, and materials are stored so they can't collapse or shift.

HSE's examples are mesh on a scaffold to keep bricks in, and exclusion zones to keep people out. Regulation 11 adds that any area where someone could fall or be struck must be clearly marked, with devices to keep unauthorised people out where reasonably practicable.

What workers must do

Regulation 14 gives you two duties. Tell the person you work for about any activity or defect linked to work at height that you know is likely to put you or anyone else in danger. And use the equipment and safety devices you're given in line with your training and instructions.

If following an instruction would be unsafe, HSE says ask for further instructions before carrying on. In practice, that's the cracked stile you take out of use, the missing guard-rail you report before your break, and the lanyard you clip on even for one quick job.

Training for work at height

The law asks for competence, and doesn't name a certificate. HSE says you don't need to be formally qualified to use a ladder, and training often happens on the job. For more technical work, such as planning a complex scaffold, HSE says industry training and certification schemes are one way to show competence.

A course covers the knowledge side. Our Working at Height course covers spotting height hazards, risk assessment, using safety equipment, the legal duties and HSE guidance, and emergency procedures. Using a mobile elevating work platform, or any other specific kit, needs separate hands-on training.

Before anyone climbs, ask whether the job can be done from the ground. If it can't, plan for any fall that could hurt someone, whatever the height. Employers training a whole team can start with workforce health and safety training.
