ESA for PoTS: How to Describe Postural Tachycardia Syndrome on the WCA
Updated June 2026 - Based on current WCA descriptor framework
Postural tachycardia syndrome (PoTS) is a form of dysautonomia: a fault in the automatic nervous system that controls heart rate and blood pressure when you change position. On standing or staying upright, blood pools in the legs and the heart races to compensate, producing a sustained rise in heart rate of at least 30 beats per minute (40 in teenagers) within ten minutes. The result is dizziness, light-headedness, a pounding heart, brain fog, breathlessness, shaking, near-fainting and sometimes full faints, along with the deep fatigue that many people with PoTS describe as the most disabling part.
The Work Capability Assessment (WCA) does not ask "do you have PoTS?" - it asks how your condition affects your ability to perform 17 specific work-related activities. To score enough points for Limited Capability for Work (LCW), you need 15 points across all 17 activities combined. For the Support Group (LCWRA on Universal Credit), you need to meet at least one Support Group descriptor or qualify another way. The point that catches most PoTS claimants out is simple: the form is built around people whose symptoms come from doing things, while PoTS symptoms come largely from being upright.
Which WCA Activities Does PoTS Affect?
PoTS reaches across both the physical and the mental and cognitive descriptors. The activities that matter most are:
- Standing and sitting (Activity 2) - the most directly relevant. PoTS is defined by what happens when you are upright, so your ability to remain at a workstation, whether standing or sitting, is the core of the claim.
- Mobilising (Activity 1) - walking and moving about set off the racing heart and breathlessness, and many people can only manage a short distance before they must stop, sit or recover.
- Consciousness during waking moments (Activity 10) - presyncope (near-fainting with greyed-out vision) and syncope (fainting) are episodes of altered or lost consciousness that this activity is designed to capture.
- Initiating and completing personal action (Activity 13) - brain fog, exhaustion and the unpredictability of symptoms make it hard to start and finish tasks reliably to a timetable.
- Coping with change and getting about - heat, travel, queueing and a fixed start time can each trigger a crash, so a rigid working pattern can be impossible to sustain.
Remember, points from ALL activities are added together, and physical and mental descriptors combine into one total. Scoring on standing and sitting, on mobilising and on personal action can take you past 15 even when no single activity does it alone. For the activity-by-activity wording, see our breakdowns of standing and sitting, mobilising and consciousness.
How PoTS Maps to the WCA Descriptors
Standing and sitting. This activity is about how long you can stay at a workstation, by standing, by sitting, or by moving between the two. For PoTS this is the heart of the claim. Sitting helps, but it does not switch the condition off - many people still feel pre-syncopal, foggy and exhausted while seated, especially with the legs down. If you cannot remain at a workstation for more than 30 minutes before you have to lie down or stop because of dizziness or a racing heart, say so plainly and describe what forces you to move.
Mobilising. This covers moving on level ground and, where relevant, climbing stairs or using aids if you cannot walk, and it looks at whether you can repeat the movement without stopping. PoTS rarely stops you walking the first few steps, but the racing heart, breathlessness and dizziness build, and the question is whether you can do it again and again across a working day. Describe how far you get before you have to stop.
Consciousness during waking moments. This activity scores involuntary episodes of lost or altered consciousness. Full faints clearly count, but so does presyncope where your vision greys out, sounds fade and you become confused or have to drop to the floor to avoid passing out. Frequency drives the score, so a precise log of how many episodes you have each month is essential. Our guide to the consciousness activity explains how the thresholds work.
Initiating and completing personal action. This is a mental and cognitive descriptor about planning, organising, starting and finishing tasks reliably. PoTS brain fog, the unpredictable timing of crashes and the fatigue that follows them all make it hard to keep to a schedule. If you regularly cannot complete two or more sequential personal actions because of fatigue and cognitive symptoms, that scores points under Activity 13.
Good Days, Bad Days and the Reliability Test
PoTS fluctuates by the hour and the day. You might feel reasonable lying down in the morning and be unable to stand by mid-afternoon, and a hot room, a missed dose, a period, a viral infection or simply having done too much yesterday can flatten you. The WCA has a built-in answer to this, often called the reliability test. To be counted as able to do an activity, you must be able to do it reliably, repeatedly, safely and within a reasonable time, for the majority of the time.
- Reliably - to an acceptable standard, not scraping through once.
- Repeatedly - again and again, as a job would demand, not a single effort that wipes you out for the rest of the day.
- Safely - without risk to yourself or others. Standing at a height, near machinery or while driving when you are prone to faints raises a genuine safety problem.
- Within a reasonable time - not at a fraction of normal speed because you keep having to sit and recover.
If you can stand for ten minutes on a good morning but not in the afternoon, and bad afternoons happen most days, you should be assessed on the bad afternoons. If standing once triggers a near-faint that stops you repeating it, you cannot do it repeatedly. Make this explicit on the form, because assessors will otherwise default to your best moment.
How to Describe PoTS on the ESA50/UC50 Form
The biggest mistake claimants with PoTS make is describing the condition in medical terms rather than work-related terms. The WCA does not care that your tilt-table test was positive or your standing heart rate hit 140 - it cares about what you cannot do reliably, repeatedly and safely in a workplace. Translate every symptom into a task.
When completing your ESA50 or UC50 form for PoTS, focus on the timeline of being upright. State how long you can stand or sit at a workstation before symptoms force you to stop, how often you feel faint or actually faint, how dizziness and brain fog affect accuracy and speed, and how long you need to recover afterwards. Use real examples: "After standing to make a drink I have to sit with my legs up for 20 minutes before the room stops spinning."
For each activity, describe your worst typical day and the pattern - how many bad days a week, and what becomes impossible on them. Our guide to what to say at your WCA assessment covers how to carry the same approach into a face-to-face or telephone assessment without underplaying your symptoms.
Evidence to Support Your Claim
Strong evidence is crucial for a successful WCA. For PoTS, gather:
- Your diagnostic test result - a tilt-table test or active stand test showing the sustained heart-rate rise on standing
- GP, cardiology or autonomic-clinic letters that confirm the diagnosis and, ideally, describe how it limits work-related tasks
- Prescription records for medication such as beta blockers, ivabradine, midodrine or fludrocortisone, and any side effects that affect function
- Fit notes or med3 certificates
- A personal diary recording standing heart rate, dizziness, near-faints and faints, with dates and how long recovery took
Ask your GP or specialist to specifically mention how PoTS affects your ability to perform work-related tasks, not just the medical diagnosis itself. Our medical evidence letter guide and evidence checklist show exactly what wording carries weight with a decision maker.
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). As a rough starting point, enter your main condition below to see the kind of figure a successful claim can reach. It is only an estimate - your real award depends on how the Work Capability Assessment scores your difficulties across the 17 activities.

Support Group (LCWRA) for PoTS
The Support Group, called LCWRA in Universal Credit, is separate from the 15-point test and means you are not expected to do work-related activity. There are three main routes for someone with PoTS:
- A Schedule 3 descriptor - for example if you cannot remain conscious during waking moments without recurrent episodes that put you or others at risk, or you cannot mobilise more than 50 metres reliably and repeatedly.
- Scoring 15 points on a single activity - severe standing and sitting limitation alone can reach the top descriptor.
- The substantial-risk rule (Regulation 35 of the ESA Regulations, Regulation 40 in Universal Credit) - if requiring you to work or do work-related activity would put your health at substantial risk, you can be placed in the Support Group even without the points. Frequent faints in unsafe settings, or severe deterioration from being made to stand or commute, are exactly the kind of risk this rule is built for.
Ask your GP or autonomic specialist to set out that risk in writing. Our guides to the substantial-risk rule and how to qualify for the Support Group explain how decision makers weigh this evidence.
Tips for Your WCA with PoTS
- Always describe limitations in work-related terms, not just medical symptoms or test results
- Build your account around being upright - how long until symptoms start, sitting and standing alike
- Log every faint and near-faint by date, since the consciousness activity turns on frequency
- Mention medication side effects, and the recovery time a crash costs you
- Describe your worst typical day, not your best, and how heat, travel and a fixed start time make it worse
- Get supporting evidence from your GP or specialist that specifically mentions work-related limitations

Frequently Asked Questions
Can you get ESA for PoTS?
Yes, you can claim ESA or Universal Credit on the grounds of postural tachycardia syndrome, but there is no automatic award for the diagnosis. The Work Capability Assessment looks at how PoTS affects your ability to carry out 17 work-related activities, so a successful claim depends on showing that the racing heart, dizziness, fainting and fatigue you get on standing or staying upright limit what you can do reliably, repeatedly and safely.
How many WCA points can PoTS score?
PoTS can score across several activities, most often standing and sitting, mobilising, consciousness during waking moments, and initiating and completing personal action. You need 15 points in total across all 17 activities to be found to have Limited Capability for Work, and physical and mental points are added together. Only the single highest-scoring descriptor in each activity counts towards your total.
Does PoTS count under the consciousness activity?
It can. The consciousness activity covers involuntary episodes of lost or altered consciousness during waking moments. Many people with PoTS experience near-fainting (presyncope) with greyed-out vision and confusion, and some have full faints (syncope). If these episodes happen at least once a month they may score points, and more frequent episodes score more. Keep a dated record of every episode, as the assessment turns on how often they occur.
How should I describe PoTS on the ESA50 form?
Describe what you cannot do rather than listing your diagnosis, and frame it around an eight-hour working day, five days a week. Explain how long you can stay upright before symptoms start, how dizziness and brain fog affect tasks, how often you feel faint or actually faint, and how long you need to recover afterwards. The assessment is based on what you can do the majority of the time, so make clear that bad days happen more than half the time if that is your reality.
What does the reliability test mean for PoTS?
To be counted as able to do an activity, you must be able to do it reliably, repeatedly, safely and in a reasonable time, for the majority of the time. Because PoTS symptoms build the longer you stay upright and vary day to day, you should be assessed on your typical bad days, not your best ones. If standing once leaves you light-headed and unable to repeat it, or doing so risks a faint, you should be treated as unable to do it.
What evidence helps a PoTS ESA claim?
Useful evidence includes a tilt-table or active stand test result confirming the diagnosis, GP or cardiology and autonomic clinic letters that link PoTS to specific work-related limitations, prescription records for medication such as beta blockers, ivabradine, midodrine or fludrocortisone and their side effects, fit notes, and a personal diary of heart rate, dizziness and faints. Ask your clinician to describe the functional impact on tasks rather than simply confirming the diagnosis.
What if my ESA claim for PoTS is refused?
If you score too few points or are placed in the wrong group, you can challenge the decision by asking for a Mandatory Reconsideration, and then appealing to an independent First-tier Tribunal if it is still refused. The most common reason claims fail is describing the condition in medical terms instead of work-related terms, so a reconsideration is often where a weak first application can be turned around.
