Reach
Can the user get close enough to the control and operate it without leaning, stretching or losing balance?

What Does “Easy to Operate” Actually Mean in Accessible Design?
Accessible products should reduce the effort, precision and complexity needed to complete everyday tasks. “Easy to operate” is not one feature: it is the combined effect of reach, grip, force, movement, feedback and consistency.
Quick answer
“Easy to operate” means a control can be reached, understood and used reliably without demanding unnecessary grip strength, finger precision, twisting, sustained force or complicated sequences. The best control depends on the person, task and environment: a long lever, large push button, sensor or automated function can each be the right answer in different situations.
A usability test, not a marketing phrase
Six things determine how easy a control really is
A product can be labelled accessible and still be awkward for a particular person. Break the action down into the physical and cognitive demands it creates.
Grip
Does the control require pinching or gripping, or can it be used with a palm, closed fist, wrist, forearm or elbow?
Force
How much effort is needed to start and complete the action, especially when it is repeated many times each day?
Movement
Does the action rely on twisting, turning through a large arc, pulling or precise finger movement?
Feedback
Is it obvious that the action has worked through movement, a click, sound, light, position change or other clear feedback?
Consistency
Can the same action be repeated predictably, or does the user have to relearn different controls around the room?
From taps to toilets
The control method changes the task
Accessible design often improves when the control is chosen around the action rather than around a conventional product format.
Long lever controls
An extended lever increases the contact area and can reduce the need for fingertip grip. Selected kitchen and bathroom taps can be operated using a closed fist, wrist, forearm or elbow.
See a long-lever kitchen tap →Quarter-turn taps
A shorter operating arc can make a conventional tap easier to use than a multi-turn mechanism, particularly where twisting is difficult.
See AKW lever taps →Sensors and touchless control
Infrared controls can remove the need to grip or turn a handle completely, although positioning, detection and user understanding still matter.
Automated functions
Shower toilets, powered lifts and other systems can replace a repeated manual task with a button, remote or programmed movement. The control itself still needs to be reachable and understandable.
One person’s easy can be another person’s difficult
Compare the whole action, not just the handle
A large handle may improve grip but still be positioned too far away. A push button may avoid twisting but require more force than expected. A sensor can remove hand effort but introduce uncertainty if its activation area is unclear.
The useful question is therefore not “is this an accessible control?” but “what does this person need to do to make it work?”
Standards & guidance
Ease of operation appears in accessibility guidance for a reason
Approved Document M for buildings other than dwellings gives a practical example: manually operated entrance-door furniture should be easy for people with limited manual dexterity, and where a latch is fitted the opening furniture should be operable with one hand using a closed fist, such as a lever handle. BS ISO 24553:2023 is a current standard specifically concerned with accessible design and ease of operation across products and controls.
One handWhere appropriate, avoid actions that force a two-handed grip or sequence.
Closed fistPart M uses closed-fist operation as a practical test for certain door controls.
Low effortForce, strength and repetitive use all affect real-world usability.
Clear feedbackOperation should be understandable, not merely physically possible.
Standards provide useful baselines, but they do not replace person-specific assessment. View Approved Document M →
Practical comparison
How to test whether something is genuinely easy to use
When possible, compare products by performing the real task rather than judging a control from a photograph or specification alone.
Approach: Can the user get close enough without an awkward reach or obstruction?
First contact: Can the control be found and engaged without fine fingertip positioning?
Operation: Can the action be completed without excessive twisting, pinching or sustained force?
Feedback: Is it clear when the control has activated and what state the product is in?
Repeat use: Would the action still feel manageable when repeated several times a day?
Shared use: If several people use the room, is the control intuitive and comfortable for more than one person?
Tactile confidence
Controls are one of the hardest things to judge online.
In the showroom you can compare lever lengths, buttons, lifting controls, rails, taps and other interfaces by feel. That can reveal differences in force and movement that a specification sheet cannot show.
FAQs
Common questions
Does accessible always mean push-button or automatic?
No. Sometimes a well-positioned lever with a large contact area is simpler and more predictable than automation. The best control is the one that reduces the barriers for the intended user and task.
Why are lever handles often easier than knobs?
A lever can usually be operated with a larger part of the hand, wrist or forearm and may require less gripping and twisting than a small round knob.
Are touchless controls always easier?
Not necessarily. They remove physical activation effort, but the sensor position and feedback need to be obvious. Some users may prefer the certainty of a physical control.
Does Part M define every accessible control?
No. Approved Document M gives guidance for particular building elements and situations. Product choice still needs to account for the actual user, environment and task.
Can I assess ease of use from a product specification?
Specifications can tell you things such as dimensions, control type and operating method, but they may not communicate how a product feels. Trying products in person can be valuable where grip or effort is important.
What should I change first if dexterity is becoming difficult?
Start with the tasks that create the most repeated effort or frustration. Taps, shower controls, handles, rails and personal-hygiene controls are common places where a relatively focused change can make a noticeable difference.
Usability first
Make the task easier, not merely different.
If a control is causing difficulty, start with the action: what has to be reached, gripped, turned, pressed or repeated? Our team can help identify products that use a different control method or reduce the effort involved.
