Working at height regulations for tradespeople: what you must know (2026 UK)

Falls from height remain the single biggest killer in UK construction. Every year the Health and Safety Executive (HSE) records more fatal injuries from falls than from any other cause — in recent years falls account for roughly a third of all construction fatalities and an even higher proportion of serious injuries to self-employed tradespeople. Roofers, window fitters, scaffolders, aerial engineers, painters and decorators, and solar installers all face this risk daily.

The legal framework is tighter than many tradespeople realise, and the HSE is not lenient when it finds breaches. This guide cuts through the legal language and tells you exactly what you must do to stay on the right side of the law in 2026.

The Work at Height Regulations 2005

The Work at Height Regulations 2005 (WAHR) implement the EU Temporary Work at Height Directive and apply across Great Britain. Despite Brexit, these regulations remain fully in force and were not amended when the UK left the EU.

The regulations apply to every employer and every self-employed person who controls work at height. If you are a sole trader fitting gutters, you are fully covered. If you are a principal contractor with subcontractors on your site, you have duties for their activities too.

Crucially, “height” does not mean a particular number of metres. The regulations define working at height as working in any place — including at or below ground level — where a person could be injured falling. A carpenter leaning into a ground-floor stairwell, a plumber working above a swimming pool void, or a roofer on a single-storey flat roof all fall within scope. There is no minimum height threshold.

Your core duties under the regulations

The regulations impose three overarching duties on duty-holders:

• Avoid work at height wherever it is reasonably practicable to do so.
• Where work at height cannot be avoided, prevent falls using suitable work equipment or other measures — prioritising collective protection.
• Where the risk of a fall cannot be eliminated, minimise the distance and consequences of any fall using appropriate equipment.

These duties must be applied in order — they form a hierarchy, not a menu of equal options.

The Hierarchy of Measures

Step 1: Avoid working at height

Before reaching for any equipment, ask: can this work be done from the ground? Telescopic window cleaning poles, long-reach painting systems, drone-based roof inspections, and remotely operated CCTV survey equipment have made ground-level working a realistic option for tasks that once routinely required access at height. If the work can safely be done from the ground, it must be — this is a legal obligation, not a preference.

Step 2: Prevent falls using collective protection

Where working at height is unavoidable, collective protection — equipment that protects everyone on the structure without them having to take individual action — must be considered first. This includes:

• Scaffolding with properly installed guardrails, toe boards and intermediate rails.
• Edge protection such as Heras fencing or proprietary edge-guard systems fitted at roof perimeters.
• Mobile Elevated Work Platforms (MEWPs) — scissor lifts, cherry pickers and boom lifts — which provide a fully enclosed working platform.
• Temporary work platforms fixed to a structure during installation or maintenance.

Only once you have genuinely considered and ruled out collective protection — and documented why — is it acceptable to move to individual fall protection systems.

Step 3: Minimise falls that do occur

Where falls cannot be prevented entirely, equipment to limit the distance and consequences must be used. This means:

• Safety nets installed below the working area to arrest a fall close to the working level.
• Soft-landing systems such as airbags used beneath fragile roof surfaces.
• Personal fall arrest systems — a full-body harness connected via a lanyard and energy absorber to a certified anchor point.
• Work restraint systems that prevent the worker from reaching the fall zone in the first place.

Ladders and Stepladders: When They’re Acceptable

Ladders are the most commonly misused access equipment in the UK trades. They are not banned — but their acceptable use is far more restricted than most tradespeople assume.

The HSE is explicit: a ladder is a means of access to a work position, not a working platform. If the job requires you to stand and work for more than a short period, or use both hands, a more suitable access solution is required. A tradesperson using a ladder to fit a window frame, lay roof tiles, or carry out overhead electrical work is very likely in breach of WAHR.

Scaffolding: Legal Requirements and Inspection

Scaffolding is required whenever work at height is not short-duration or low-risk enough to justify a ladder, and where a MEWP is impractical. For most domestic roofing, chimney, fascia and soffit work, scaffolding is the legally appropriate solution.

The industry standard is TG20:21, the NASC guidance document covering tube-and-fitting and system scaffolding design. Compliance with TG20 is not itself a legal requirement, but scaffolding that deviates from it must be designed by a qualified engineer — making TG20 the practical baseline for almost all domestic and small commercial work.

Under Schedule 7 of WAHR, scaffolding must be inspected and the results recorded in writing:

• Before first use after erection.
• After any event that could affect its integrity — high winds, impact by a vehicle, heavy snow loading.
• At intervals not exceeding seven days while in use.

Inspection must be carried out by a competent person. The written record must be kept available for inspection until the scaffolding is dismantled, and for a further three months thereafter.

MEWPs: Scissor Lifts, Cherry Pickers and Boom Lifts

Mobile Elevated Work Platforms offer a fully enclosed, guardrailed working platform and are often the safest and most efficient access solution for commercial facade work, street lighting, tree surgery and industrial maintenance.

IPAF certification (from the International Powered Access Federation) is the recognised standard for MEWP operators in the UK. While not a statutory requirement, most principal contractors and facilities managers will insist on a valid IPAF card before allowing a MEWP on site — and operating without proper training will be treated as negligence by the HSE in the event of an incident. IPAF categories cover different machine types: 1a (vehicle-mounted), 1b (self-propelled boom), 3a (scissor lift) and 3b (self-propelled boom with unrestricted working envelope).

Before operating a MEWP: check ground conditions (firm, level surface or stabilisation mats), deploy outriggers fully if fitted, check overhead obstructions including power lines, and ensure the MEWP has a valid LOLER thorough examination certificate (12-monthly for most MEWPs, six-monthly for those used to carry people).

Roof Work: Specific Requirements

Roof work — whether on pitched domestic roofs, flat commercial roofs, or fragile industrial roofing — carries the highest risk of fatal falls and attracts the most HSE enforcement activity.

For pitched domestic roofs, edge protection at eaves level (typically scaffold with a guardrail, toe board and intermediate rail) is the standard requirement. Crawling boards are needed on fragile or steep pitches. Ridge anchors with fall arrest lanyards are appropriate for short-duration work above the eaves scaffold level.

For flat commercial roofs, the perimeter must be protected by guardrails or, where that is not practicable, by a warning line system with a dedicated safety monitor and written evidence that the arrangement is appropriate for the risk. Safety nets below fragile rooflights are a legal requirement where there is any risk of a person falling through.

The HSE’s guidance document HSG33: Health and Safety in Roof Work remains the definitive reference and is freely available on the HSE website. Any roofer who has not read it should do so.

Risk Assessment: What You Must Document

A risk assessment is mandatory for all work at height. The level of detail required is proportionate to the risk: a quick mental assessment may suffice for a tradesperson spending two minutes on a stable ladder to change a light fitting, but a written assessment is required wherever the risk is significant.

For any work involving scaffolding, MEWPs, harnesses, roof work, or work by multiple operatives, a written risk assessment and method statement (RAMS) are expected. The RAMS must be specific to the task — a generic document that does not reflect the actual site conditions is worth little in an enforcement context and will not protect you if an incident occurs.

RAMS should cover: the scope of work, identified hazards, control measures, PPE requirements, emergency and rescue arrangements, and the competence of operatives carrying out the work.

The Rescue Plan: A Requirement, Not an Afterthought

Any time a personal fall arrest harness is used, a rescue plan must exist before work begins. This is not optional — it is explicitly required by WAHR and is one of the most commonly missed requirements in practice.

The reason is physiological and urgent: a worker suspended in a harness after a fall can suffer suspension trauma (also called orthostatic shock) within minutes. Blood pools in the legs, cardiac output drops, and the worker can lose consciousness and die — even without any injury from the fall itself. The emergency services alone cannot be relied upon; typical response times are far too long.

A rescue plan must specify who will carry out the rescue, what equipment will be used (a rescue kit, a second operative with a lowering device, or pre-arranged emergency access), and how quickly the suspended worker will be recovered to safety. If you cannot answer those questions before starting work, you should not be using a harness system.

HSE Enforcement and Penalties

HSE inspectors have the power to enter any workplace without notice. When they identify a breach of WAHR, they have a range of enforcement options:

• Verbal advice for minor issues that are rectified on the spot.
• Improvement notices requiring specific action within a set timeframe.
• Prohibition notices stopping work immediately — the site cannot reopen until the HSE is satisfied the risk is controlled. These can be applied to a single activity, a piece of equipment, or the entire site.
• Prosecution for serious or repeated breaches. Since the Sentencing Council’s 2016 health and safety guidelines, fines for organisations have run to millions of pounds based on turnover and culpability. For individuals, fines are unlimited and imprisonment of up to two years is available for the most serious offences.

The HSE publishes all prosecutions on its website. Being named there — as well as the reputational and insurance consequences — can be as damaging as the fine itself for a small trades business.

Common Mistakes UK Tradespeople Make

HSE incident investigations repeatedly identify the same patterns of failure:

• Using an unsecured ladder for roof work. Leaning a ladder against a gutter and climbing onto the roof without edge protection is one of the leading causes of fatal falls.
• Not inspecting scaffolding. Scaffold erected weeks earlier may have been altered, damaged by weather, or have components removed. Weekly written inspections exist because conditions change.
• No rescue plan when using harnesses. A harness without a rescue plan does not make work safe — it may simply change the cause of death from impact injury to suspension trauma.
• Working alone at height. Working alone dramatically increases risk when a fall occurs, as there is no one to call for help or initiate rescue. WAHR does not prohibit lone working at height but requires the risk assessment to address it explicitly.
• Using a tower scaffold on uneven ground. A PASMA-compliant tower must be erected on level, firm ground. Setting it up on a slope or soft ground without appropriate base plates and outrigger feet invalidates the safety case.
• No written RAMS for higher-risk work. Relying on a verbal briefing or a generic document is not adequate when the HSE or a civil court examines what controls were in place before an incident.

Keeping Compliance Documents Accessible

The paperwork burden around height safety is real: risk assessments, method statements, scaffold inspection logs, IPAF and PASMA certificates, harness inspection records, LOLER thorough examination reports. Keeping these tied to the right job — and being able to produce them quickly when an HSE inspector or a main contractor asks — is where many small trades businesses fall down.

Trade2Base lets you attach documents directly to job records, so your RAMS for a roofing contract sits alongside the quote, the programme and the sign-off — not buried in a folder on someone’s laptop. Certificates for operatives can be stored against their profiles with expiry alerts, so you know before a job starts whether anyone’s IPAF card needs renewing.

Working at height safely is not complicated — but it requires deliberate planning, the right equipment, and documentation that stands up to scrutiny. The hierarchy of measures, a genuine risk assessment, and a rescue plan before any harness goes on: those three habits will keep your operatives alive and your business out of the HSE’s prosecution list.
