Display Screen Equipment (DSE) Regulations: What UK Trade Businesses Need to Know (2026)

What Are the DSE Regulations?

The Health and Safety (Display Screen Equipment) Regulations 1992 — usually shortened to "the DSE Regulations" — sit underneath the Health and Safety at Work etc. Act 1974. They were amended in 2002, and the Health and Safety Executive (HSE) publishes guidance (L26) explaining how to comply. "Display screen equipment" means any alphanumeric or graphic display screen, regardless of the display process involved. In plain English that covers desktop monitors, laptops, tablets and similar devices used for work.

The point of the rules is not to ban screen work. It is to control the well-documented health risks of prolonged computer use: musculoskeletal problems in the back, neck, shoulders, arms and hands; visual fatigue; and stress. The Regulations put specific, practical duties on employers to assess and reduce those risks for the people who do this work regularly.

Who Counts as a DSE "User"?

This is the question that decides whether the Regulations bite. The duties apply to "users" and "operators". A "user" is an employee who habitually uses display screen equipment as a significant part of their normal work. An "operator" is a self-employed person who does the same. There is no single hour threshold in law, but HSE guidance says someone is generally a user if they use DSE for continuous or near-continuous spells of an hour or more at a time, more or less daily, and the work depends on the screen with limited choice about using it.

For a trade business that matters in two common situations. First, your office or admin staff. The person who raises your invoices, chases payments, books jobs, manages your CRM and does your VAT return is very likely a DSE user — even though the "real" risks of your business are on site. Second, you. If you are a self-employed sole trader who spends most evenings and a good chunk of the working week quoting, scheduling and doing the books at a laptop, you can be an "operator" and the workstation requirements still apply to your own equipment.

People who only use a screen occasionally — a fitter who logs a job sheet on a tablet for a few minutes, or someone who checks email once or twice a day — are generally not classed as users. The deciding factors are the duration, intensity, frequency and how much the work depends on the screen.

Your Duties as an Employer

If you have DSE users, the Regulations give you a clear, finite set of duties. None of them are onerous for a small firm, but you do need evidence you have done them.

The Workstation Minimum Requirements

The Schedule to the Regulations sets out what a compliant workstation looks like. You do not need to buy expensive ergonomic furniture for everyone — you need workstations that can be adjusted to suit the individual. The core requirements are:

• Screen: stable image, no flicker, adjustable brightness and contrast, able to tilt and swivel, free of distracting reflections and glare.
• Keyboard: separate from the screen and tiltable, with enough space in front to rest hands and arms, and clearly legible characters.
• Desk: large enough for the screen, documents and equipment, with a low-reflectance surface and room for a comfortable working posture.
• Chair: stable, adjustable in seat height, with an adjustable backrest for height and tilt; a footrest provided on request.
• Environment: adequate lighting and contrast, controlled glare and reflections, no excessive noise or heat, and reasonable humidity.
• Software: suitable for the task and the user, easy to use and adaptable to their level of knowledge.

A common, cheap fix that solves most problems for a laptop user is a separate keyboard, a separate mouse and a laptop riser (or a separate monitor) so the screen sits at eye level. A laptop used directly on a desk for hours forces a bent neck and is one of the most frequent issues an assessment turns up.

Eye Tests and Glasses — What You Actually Pay For

If a DSE user asks for an eye and eyesight test, you must arrange and pay for one. You also have to offer further tests at intervals recommended by the optometrist, and a test if the user is having visual difficulties that may be down to screen work. You are paying for the test itself — you cannot insist the employee uses their own optician if that means they pay.

On glasses, the rule is narrower than people assume. You only have to contribute to spectacles where the test shows the user needs them specifically for DSE work — for example, a prescription set for the intermediate screen distance that their normal glasses do not cover. You are only required to fund a basic pair adequate for the job. If the user wants designer frames or lenses that also serve their everyday vision, you are not obliged to cover the extra cost. If their normal prescription glasses are fine for screen work, you owe nothing toward glasses at all.

Homeworkers, Laptops and Tablets on Site

Since more admin work happens away from a fixed office, two scenarios come up a lot in trade firms. The first is homeworking. If a DSE user does some or all of their work from home — a bookkeeper one or two days a week, say — the Regulations still apply and you must assess their home workstation. In practice that is done with a self-assessment checklist the worker completes and returns, which you review and act on. You should provide or fund the equipment they need to work safely, such as a separate keyboard and mouse or a riser.

The second is portable devices. Laptops and tablets are within scope when used for a significant period. They are not designed for prolonged use in their bare form, so where a laptop is someone's main work device you should provide the accessories that turn it into a proper workstation. A tablet used briefly on site to capture a signature or photo is unlikely to make that person a user — but a member of staff sitting in the van or site office doing schedule and admin work on a tablet for hours is a different matter.

How Often Should You Reassess?

There is no fixed legal interval, but the assessment must be kept up to date. You should review a workstation assessment when something changes that could affect it, such as:

• A new starter takes over a workstation, or someone moves desk.
• You change the equipment, furniture, software or move to new premises.
• The nature or intensity of the work changes — for example, more hours at the screen.
• A user reports discomfort, eye strain or a relevant health issue.
• Working arrangements change, such as a shift to regular homeworking.

As a sensible baseline, many small firms re-run the checklist annually and whenever one of the triggers above occurs. The key is being able to show you reviewed it and acted, not hitting an exact date.

Common Failings in Small Trade Firms

Most non-compliance is not deliberate — it is simply that the office side gets overlooked while attention sits on the site risks. The recurring problems are:

• Assuming it does not apply: "We're a building firm, not an office" — but the admin role clearly involves a DSE user.
• No written assessment: the chair and screen are fine, but there is no record, so there is nothing to show an inspector or after a complaint.
• Laptop on a desk all day: the most common workstation issue, easily fixed with a riser, keyboard and mouse.
• Ignoring homeworkers: staff working from home with no home-workstation check.
• Not handling eye-test requests: unaware the request must be funded, or unsure what they owe toward glasses.
• No breaks built in: a busy estimator at the screen for hours with no change of task.

Remember this sits alongside your trade-specific health and safety, not instead of it. DSE compliance does not reduce your duties on working at height, manual handling, COSHH, electrical safety or anything else on site. It is an additional, narrow area that applies to the desk-based part of the business.

How to Do a DSE Assessment — Step by Step

You do not need a consultant for a typical trade-firm office. A competent person within the business can complete a workstation assessment using the free HSE DSE checklist. Here is a practical sequence:

• 1. Identify your users. List everyone who uses a screen as a significant part of their normal work, including yourself if relevant and any homeworkers.
• 2. Use a structured checklist. Download the HSE DSE workstation checklist (or use an equivalent) so you cover screen, keyboard, mouse, desk, chair, environment and software consistently.
• 3. Involve the user. Go through it with the person at their actual workstation — they know where the glare, the awkward reach or the aching shoulder is.
• 4. Adjust and fix. Sort the easy wins on the spot: raise the chair, reposition the monitor, add a riser, cut glare. Note anything that needs purchasing.
• 5. Record the outcome. Keep the completed checklist, the actions taken and the date. This record is your evidence of compliance.
• 6. Provide information. Make sure each user knows about good posture, taking breaks, adjusting their setup and how to request an eye test.
• 7. Review. Re-run it when something changes or on your annual cycle, and close out any outstanding actions.

Penalties and Enforcement

The DSE Regulations are enforced under the Health and Safety at Work etc. Act 1974, with the HSE (or your local authority, for some office-based premises) as the enforcing authority. Inspectors can issue improvement notices requiring you to put things right within a set time, and prohibition notices stopping an activity where there is a risk of serious personal injury.

Failing to comply with the underlying duties is a criminal offence. Cases dealt with in the magistrates' court can attract unlimited fines, and serious breaches can be sent to the Crown Court. In reality, prosecution purely over a screen workstation is rare — but DSE failings commonly surface during a wider inspection or after an employee raises a concern or makes a personal-injury claim for an upper-limb disorder. The cheapest insurance is a completed assessment on file showing you took the issue seriously.

Frequently Asked Questions

Do the DSE Regulations apply to a one-person trade business?

If you are genuinely self-employed and the only person in the business, the employer duties to others do not apply — but the workstation minimum requirements apply to your own setup if you are a DSE "operator", and your general duty to manage your own health and safety still stands. The moment you take on an employee who uses a screen significantly, the full duties apply.

My admin only does about an hour of computer work a day — are they a user?

Possibly not, if that hour is broken up and the rest of their work is off-screen. There is no fixed threshold, but a genuinely light, intermittent user generally is not a "user". Look at duration, intensity, frequency and how dependent the work is on the screen. When in doubt, doing a short assessment anyway costs little and removes the risk.

Do I have to buy expensive ergonomic chairs?

No. The chair must be stable and adjustable for seat height, with an adjustable backrest, and a footrest on request. A standard adjustable office chair meets this. You are buying adjustability and suitability, not a premium brand.

Does using a phone for work count as DSE?

Smartphones used briefly are generally outside the scope. If a device with a small screen is being used intensively for prolonged work, the risks should still be managed, but normal phone use to make calls, check messages or take a photo on site does not make someone a DSE user.
