PUWER Explained — Work Equipment Safety for Trade Businesses (2026)

What Is PUWER and Who Does It Apply To?

PUWER is the set of regulations made under the Health and Safety at Work etc. Act 1974 that governs the safety of work equipment. It is enforced by the Health and Safety Executive (HSE) and, in some sectors, local authorities. The core principle is simple: equipment provided for use at work must be safe, suitable for the job, properly maintained, and used only by people who are trained and competent to use it.

PUWER applies to any employer or self-employed person who provides or uses work equipment. That means it covers you whether you have a team of fitters or you're a one-person operation working out of a van. It also applies where you let employees provide their own tools, or where equipment is hired in. If you control how work equipment is used in your business, the duty sits with you.

It is not limited to big machinery. A self-employed plumber using a cordless drill, a roofer climbing a ladder, a joiner running a bench saw, a groundworker on a mini-digger — all of them are using "work equipment" within the meaning of PUWER.

What Counts as "Work Equipment" and "Use"?

"Work equipment" is defined very broadly. It includes any machinery, appliance, apparatus, tool or installation used at work. In practice, for a trade business that captures:

• Hand tools and power tools — drills, grinders, sanders, nail guns, breakers
• Bench and fixed machinery — bench saws, planers, pillar drills, abrasive wheels
• Access equipment — ladders, steps, trestles, towers, podiums
• Plant and vehicles used as equipment — mixers, compressors, generators, mini-diggers, dumpers
• Van-mounted equipment — power washers, welfare units, racking, vehicle-mounted lifts

"Use" is equally wide. It covers any activity involving the equipment — starting, stopping, programming, setting, transporting, repairing, modifying, maintaining, servicing and cleaning. So the moment someone touches a machine to clean or adjust it, PUWER still applies, not just when it's running on the job.

The Core Duties Under PUWER

PUWER sets out a handful of general duties that run through everything. Get these right and you've covered the bulk of what an inspector would expect to see. Equipment must be:

• Suitable for the task: the right equipment for the job and the working conditions. Using a domestic drill for continuous heavy-duty work, or the wrong access equipment for a height task, fails this test.
• Maintained in efficient working order and good repair: equipment must be kept safe through the life of the asset, with maintenance carried out as needed.
• Inspected where safety depends on installation or conditions: where the safety of equipment depends on how it was installed or on conditions that deteriorate, it must be inspected after installation and at suitable intervals.
• Used only by trained and competent people: anyone using, supervising or managing the equipment must have adequate training and competence for the risks involved.
• Accompanied by adequate information and instructions: operators and supervisors must have the health and safety information they need — manufacturer instructions, written procedures and warnings where appropriate.

Specific Risk Controls

Beyond the general duties, PUWER lists specific hardware and control requirements aimed at the most common ways people get hurt by machinery. Depending on the equipment, you may need to ensure:

• Dangerous parts are guarded: moving parts that can cause injury — blades, gears, rotating shafts, drive belts — must be guarded or have other protective measures so contact is prevented.
• Protection against specified hazards: measures against ejected parts, overheating, fire, explosion and discharge of substances such as dust, gas or fluid.
• Suitable controls and emergency stops: clearly identified start, stop and operating controls, plus an emergency stop where the risk warrants one.
• Isolation from energy sources: a means to isolate equipment from its power supply — electrical, pneumatic, hydraulic — so it can be worked on safely.
• Stability: equipment must be stabilised by clamping, fixing or other means where necessary to prevent it tipping or moving in use.
• Adequate lighting: suitable and sufficient lighting for any operation involving a risk.
• Markings and warnings: clear markings (such as maximum rotation speeds on abrasive wheels) and warning devices where they are needed for safety.

Maintenance and Inspection

Two separate but related duties cause the most confusion: maintenance and inspection. They are not the same thing.

Maintenance is about keeping equipment safe and in efficient working order across its life — servicing, replacing worn parts, fixing faults. How often depends on the equipment, how hard it's used and the manufacturer's recommendations. Where there is a maintenance log, keep it up to date; it is good evidence you've met the duty.

Inspection under PUWER is required where the safety of equipment depends on the installation conditions or where it is exposed to conditions that cause deterioration likely to result in a dangerous situation. Inspection must happen after installation (or after assembly at a new site) and at suitable intervals. The result of inspections must be recorded and kept until the next inspection is recorded.

For lifting equipment, PUWER works alongside the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER). A PUWER inspection is a relatively routine check that the equipment is safe to use; a LOLER thorough examination is a more rigorous, scheduled examination by a competent person — typically every 6 months for equipment lifting people or accessories, and every 12 months for other lifting equipment, or in line with an examination scheme. If you use slings, chains, hoists, a tail-lift or a vehicle-mounted crane, you need to satisfy both regimes: PUWER for general work-equipment safety and LOLER for the lifting-specific examinations.

PUWER Duties at a Glance

Practical Examples for Trades

PUWER is easiest to understand through the equipment you actually use day to day. Here's how the duties land for common trade situations.

Bench Saws and Abrasive Wheels

Fixed cutting machinery is where guarding matters most. A bench saw needs a crown guard, riving knife and properly set fences; an angle grinder or chop saw needs the wheel guard kept in place. Abrasive wheels carry their own well-known requirements — only trained operators should mount wheels, the maximum permissible speed must be marked and observed, and the wheel must be inspected for damage before fitting. PUWER sits behind all of this as the general work-equipment duty; specific abrasive wheel competence is part of meeting it.

Power Tools and PAT Testing

Electrical hand tools must be maintained so they stay safe — frayed leads, cracked casings and damaged plugs are common failures. Portable Appliance Testing (PAT) is one practical way to demonstrate electrical equipment is in good order, alongside user pre-use checks. PAT is not a legal requirement in its own name, but the underlying duty to maintain electrical work equipment is, and a documented inspection regime is strong evidence you've met it.

Cement Mixers and Plant

A cement mixer has a rotating drum and an exposed drive at the back — both need guarding so clothing and limbs can't be caught. Compressors, generators and breakers all need to be suitable, maintained and used by people who know how to operate them. Hired-in plant doesn't escape PUWER; you still need to check it's safe before use and that your operators are competent.

Blade and Consumable Condition

A blunt, chipped or cracked blade is a safety issue, not just a quality one — it increases the risk of kickback and binding. Pre-use checks on blades, discs and cutting consumables are part of keeping equipment in efficient working order. Build a quick visual check into the start of every task.

Training Records

Competence is a recurring theme in PUWER. Keep records of who is trained on what — abrasive wheels, MEWPs, plant, specific machines. If an inspector asks how you know an operator is competent, a dated training record answers the question far better than "they've always done it".

Why PUWER Matters

Work equipment is involved in a large share of serious workplace accidents — contact with moving machinery, struck-by ejected material, and falls from unsafe access equipment among them. The HSE treats equipment safety failures seriously: it can issue improvement and prohibition notices, and breaches can lead to prosecution and substantial fines, particularly where there's a clear failure to guard machinery or maintain equipment.

PUWER doesn't sit in isolation. It works hand in hand with your risk assessments and method statements (RAMS) — your risk assessment should identify the equipment hazards, and your controls should reflect the PUWER duties for guarding, maintenance, inspection and competence. For lifting work, cross-reference LOLER and its thorough examination requirements. For cutting and grinding, the abrasive wheel rules sit underneath PUWER. Treat them as one connected system rather than separate boxes to tick.

For a small trade business, the practical takeaway is straightforward: buy or hire suitable equipment, keep it maintained and inspected with records to prove it, guard the dangerous bits, and make sure only trained people use it. Do that, and you've met the heart of PUWER while genuinely reducing the chance of someone getting hurt.
