What are the requirements?
Employees who use a
DSE for around 2 hours
each day require an
assessment. The
assessment seeks to
minimise risks & inform
employees on how to
work safely with DSE.
Who carries out the workstation
DSE self assessments will be completed
regularly (i.e. after office/desk moves or
annually) by all staff. H&S Team will review
completed self assessments and either close
out any issues or assist managers to close
out issues such as new chairs, screens,
hardware, software and/or specialist
equipment etc.
Staff including Home workers and those
hotdesking (sharing a workstation) should be
instructed on how to undertake their own
assessments and to set up their DSE
What is covered by a DSE risk
Is there adequate lighting?
Is there adequate contrast & no glare or
Is noise minimised?
Is there sufficient legroom?
Are there window coverings if needed?
Is the software appropriate to the task?
Is the screen image stable?
Is the screen adjustable?
Is the keyboard adjustable, detachable and
the keys legible?
Does the work surface have space for the
required equipment and free from glare?
Is the chair stable and adjustable?
Are there footrests, armrests, wrist rests,

The Line Manager of the person assessed must
ensure that recommendations are implemented.
Workstation assessments must be reviewed on a
regular basis and following changes to the
workplace/workstation or work patterns.
Does DSE pose a health risk?
No, providing that the workstation is set up in
such a way that it doesn’t pose a risk to the user
(refer to the diagrams below).
Health risks tend to be as a result of a failure in
the factors examined in the risk assessment, such
Unsuitable equipment i.e. the wrong type of
chair, desk, keyboard, mouse etc.;
Broken equipment e.g. chair or monitor not
fully adjustable or screen flickers;
Poor posture e.g. slouching at the
workstation; the user not fully adjusting the
chair and workstation to their needs;
Poor working environment e.g. broken or
unsuitable lighting; glare; lack of space.
Should the risk assessment highlight problems
associated with repetitive strain injury or work
related upper limb disorders the member of staff
should consult their GP. Any recommendation
that may require a change in the workstation set
up (i.e. ergonomic mouse, type of chair etc). An
Occupational Health appointment may be
required for a further assessment. H&S Group
should be consulted for further guidance &
Any ill health that may be associated with DSE
use must be reported to line managers.

ergonomically efficient manner.
