WCA Activity 4: Picking Up and Moving by the Upper Body and Arms

Activity 4 of the Work Capability Assessment has the full title "picking up and moving or transferring by the use of the upper body and arms." In plain terms it asks one question: can you lift and carry everyday objects using your arms and upper body? It is one of the 17 activities the WCA uses to decide whether you have Limited Capability for Work, and it is a physical activity, so the points you score here add to anything you score on the mental and cognitive activities.

You score points on this activity by showing that you cannot reliably lift and move objects of a defined size. The test deliberately uses small, light items - a half-litre carton, a one-litre carton, and an empty cardboard box - rather than heavy weights, because the law is interested in basic everyday function, not whether you could do a labouring job. If even these light tasks are beyond you for the majority of the time, you score, and the lighter the object you struggle with, the higher the points.

The Activity 4 descriptors and exact point values

These are the descriptors exactly as written in Schedule 2 of the Employment and Support Allowance Regulations 2013. The same descriptors apply to Universal Credit through the equivalent rules. Only the single highest-scoring descriptor that applies to you counts.

In plain English:

• 15 points if you cannot pick up and move a half-litre carton full of liquid. That is roughly a small carton of juice or a half-litre water bottle - well under half a kilogram. If even that is beyond you most of the time, this is the highest-scoring descriptor.
• 9 points if you cannot pick up and move a one-litre carton full of liquid (about a standard carton of milk, around a kilogram). You can manage the half-litre but not the litre.
• 6 points if you cannot transfer a light but bulky object such as an empty cardboard box. Weight is almost nothing here - the difficulty is the shape and the reach and grip needed to move something awkward.

How a real difficulty maps to a descriptor and points

Points only make sense when you see how an everyday problem turns into a specific descriptor. Here is a composite example built from the kind of facts an assessor weighs. The figures are not invented - they are the descriptor points written into Schedule 2.

Imagine someone with osteoarthritis in both shoulders and weakness in the right arm after a previous injury. They can lift a light glass to drink, but a full kettle is too heavy and painful, and by the afternoon even small lifts trigger sharp pain. They cannot carry a full carton of milk from the fridge to the table without putting it down halfway.

• Descriptor (b) - cannot pick up and move a one litre carton full of liquid: they can just about manage the half-litre on a good morning, but a one-litre carton is consistently beyond them, so descriptor (b) at 9 points is the best fit on most days.
• If their condition worsened so that even the half-litre carton could not be moved reliably, the score would rise to descriptor (a) at 15 points, which alone meets the threshold for Limited Capability for Work.

Two things matter. First, only the highest descriptor that applies counts, so you do not add (b) and (c) together within Activity 4. Second, those 9 points are not the end of the story - they combine with points from related activities to reach the 15-point threshold.

The reliability test applied to lifting and carrying

The single most important idea in the whole assessment is that you must be able to do an activity reliably, repeatedly, safely, in a reasonable time, and for the majority of the time. An assessor is not asking whether you could lift a carton once. They are asking whether you could do it again and again through a real working day. For Activity 4 this test does a lot of the work.

• Reliably and repeatedly. Lifting a carton once at the start of the day is not the same as doing it every few minutes for hours. If pain, weakness or fatigue mean the third or fourth lift is impossible, you cannot do it repeatedly, and the descriptor can apply.
• Safely. If your grip is unreliable and you are likely to drop a full carton, or if lifting risks dislocating a joint or worsening a tear, then you cannot do it safely. A dropped object is a hazard in any workplace.
• In a reasonable time. If a lift that should take a second takes you far longer because you have to brace, rest and try again, that is itself a way of failing the descriptor.
• The majority of the time. This is the "more than half the days" rule. If your bad days, when even light lifting hurts, add up to more than half the month, the law says you should be assessed as you are on those days.

When you write your form, attach this test to each difficulty. Do not just say "I have a bad shoulder." Say "I cannot move a one-litre carton because my grip gives way and the weight triggers pain, and I cannot repeat the lift through the day."

Which conditions commonly score on Activity 4

Any condition that weakens the arms, reduces grip, or makes lifting painful can be relevant. Common ones include:

• Arthritis in the shoulders, elbows, wrists or hands. See our guide on ESA for arthritis for how joint disease maps across several activities.
• Frozen shoulder, rotator cuff tears and other shoulder injuries that limit the power and range to lift.
• Stroke with weakness or loss of function in one arm - see ESA for stroke.
• Multiple sclerosis and other neurological conditions causing weakness, tremor or fatigue - see ESA for MS.
• Fibromyalgia and chronic fatigue, where strength can be normal at rest but collapses with repetition.
• Nerve damage and carpal tunnel, where grip becomes unreliable - see ESA for carpal tunnel.

There is no automatic award for any diagnosis. What scores points is the functional effect of your condition, described against the descriptors, not the name of the condition itself.

Evidence to gather for Activity 4

Lifting and carrying problems are hard to observe in a short telephone consultation, so written evidence carries weight. Build it in layers:

• GP records. Ask for a printout of your consultation history and medication list. The record often shows years of logged pain, weakness and joint problems.
• Specialist letters. A rheumatologist, orthopaedic surgeon, neurologist or physiotherapist can confirm the diagnosis and describe the impact on strength and movement.
• Scans and imaging. X-rays, MRI or ultrasound results showing joint damage, tears or nerve compression are objective support.
• Occupational therapy assessments. An OT report describing what you can and cannot manage at home, including lifting and carrying, is directly relevant.
• Your own examples. Write down concrete, everyday failures - cannot lift a full kettle, cannot carry a bag of shopping, have to use both hands for a mug and still spill it. These map directly onto the carton and box descriptors.

Our ESA evidence checklist walks through what to send and how. Send copies, never originals, and keep a list of everything you submit.

Common mistakes on Activity 4

• Describing your best moment. People naturally say what they can do on a good day. The assessment is about the majority of the time, including the days when even a half-litre carton is too much.
• Forgetting repetition. Many people can manage a single lift but not the same lift repeated through a working day. Say so - repeatedly is part of the legal test.
• Ignoring pain and safety. If you can technically lift the carton but only with severe pain, or if you are likely to drop it, that is relevant. "Can do it but not safely or reliably" is a valid answer.
• Treating Activity 4 in isolation. Upper-limb problems usually affect several activities at once. Score them all, not just this one.

How Activity 4 combines towards the 15-point threshold

You need 15 points in total to be treated as having Limited Capability for Work. Physical and mental points are added together across all 17 activities, and Activity 4 rarely stands alone. Upper-limb conditions usually affect a cluster of related physical activities:

• Activity 1 - Mobilising, if the same condition affects walking or using stairs.
• Activity 3 - Reaching, since the shoulder movements overlap with lifting.
• Activity 5 - Manual dexterity, where grip and hand function are affected.

For example, 9 points on Activity 4 plus 6 points on Reaching reaches 15 on physical activities alone. Or 9 points here plus points from a mental health activity such as coping with change could combine to the same total. This is why describing every affected activity matters: a refusal often happens because someone scored 9 on one activity and stopped, when a second activity would have carried them over the line. Read how many points you need for ESA for the full arithmetic.

Activity 4 and the Support Group

Activity 4 is not one of the Schedule 3 descriptors that directly place you in the Support Group (LCWRA on Universal Credit). However, the substantial-risk rule can still apply if being found capable of work-related activity would put your physical or mental health at serious risk. If your upper-limb condition is severe and combined with other problems, you are more likely to reach the Support Group through the overall picture than through this single activity. Our guide to qualifying for the Support Group explains the routes in more detail.

The consultation, the decision and challenging it

Most assessments are now carried out by telephone or as a paper-based review of your form and evidence, although a face-to-face appointment is still possible. Because an assessor cannot watch you try to lift a carton over the phone, your written account and your medical evidence do most of the work. Answer for your typical and worst days, not your best one, and add the qualification "yes, but not safely, not reliably, and not repeatedly" where it is true.

After the assessment the DWP sends a decision letter. If you are refused, or placed in the Work-Related Activity Group when you believe you should be in the Support Group, you can challenge it. Read the assessment report - you can ask the DWP for a copy - and check it against what you actually said.

The challenge runs in two stages. First, Mandatory Reconsideration: you ask the DWP to look again, normally within one month, setting out which descriptors you meet and why, with any fresh evidence. If that does not fix it, you can appeal to the First-tier Tribunal, an independent panel that includes a doctor. Many decisions are overturned at tribunal because the panel takes the time to understand how a fluctuating physical condition affects everyday lifting and carrying.

WCA reform: what is changing

The Work Capability Assessment is under reform, with changes announced from 2025 onwards as the government moves towards assessing health-related support differently within Universal Credit. The descriptors and point values described here are the rules that apply now. If you have an assessment or a decision in progress, the current rules are what your claim is judged against. Keep an eye on GOV.UK for the latest, and see our overview of ESA and WCA changes.

Frequently Asked Questions

How much could your ESA be worth?

The amount depends on whether you reach the 15-point threshold for Limited Capability for Work, and whether you qualify for the Support Group (LCWRA), paid at £145.90 a week, rather than the Work-Related Activity Group at £95.55 a week.
