The ESA Assessment Phase and the Lower Assessment Rate

Updated June 2026

When you first make an Employment and Support Allowance claim, you do not go straight onto the full rate. Instead you enter the assessment phase, a period of roughly the first 13 weeks during which you are paid a lower assessment rate while the Department for Work and Pensions (DWP) carries out the Work Capability Assessment (WCA) and decides which group you belong in. This guide explains why the assessment rate exists, how long the phase really lasts, what you should be doing during it, and what changes once a decision is finally made.

What the assessment phase actually is

The assessment phase is the opening stage of every ESA claim. Its purpose is to give the DWP time to gather information about your health and decide, through the Work Capability Assessment, whether you have limited capability for work and, if so, whether you should be in the Support Group or the Work-Related Activity Group (WRAG). Until that decision is made, the DWP does not know which rate you are entitled to, so it pays a holding rate - the assessment rate - to make sure you have income coming in while the process runs.

It helps to remember what the WCA is testing. Unlike Personal Independence Payment, which looks at the extra costs of daily living and mobility, the WCA looks only at your capability for work. You score points across the WCA activities, and reaching the threshold establishes limited capability for work. The assessment phase is simply the window in which that scoring and decision-making happens. You can read more about the test itself in our complete Work Capability Assessment guide and our explanation of what limited capability for work means.

Why is the assessment rate lower?

The logic is straightforward. At the start of your claim the DWP has not yet confirmed that you have limited capability for work, and it has not decided which group you should be in. The two main-phase groups pay different amounts: the Support Group, for people with the most serious limitations, pays a higher weekly amount than the Work-Related Activity Group. Because the DWP cannot know which of these applies until the WCA is done, it pays a basic rate in the meantime.

Once the assessment is complete and you are placed in a group, your payment usually increases. People placed in the Support Group receive a support component on top of the basic amount, while those placed in the WRAG receive a smaller work-related activity component (newer claims are affected by the reduction in the WRAG component that applied from 2017 onwards). For the exact current weekly figures, always check the rates on GOV.UK, because they are reviewed each year. You can also see a plain-English breakdown on our ESA rates 2026 page.

How long the assessment phase really lasts

On paper the assessment phase is meant to last 13 weeks. In reality it often runs longer, sometimes considerably so, because of the time it takes to issue the ESA50 questionnaire, arrange a Work Capability Assessment and make a decision. This is normal and does not mean anything has gone wrong with your claim.

The key point to understand is that you do not automatically jump to a higher rate at the end of week 13. The increase only happens once the WCA confirms you have limited capability for work and places you in a group, and it is worth knowing how long after a WCA you get a decision so a slow decision does not take you by surprise. If that decision is made after week 13, you remain on the assessment rate until it lands, and the extra money is then usually backdated to the start of week 14. So while a long wait is frustrating, it does not normally cost you money in the end, because the arrears make up the difference.

What you should be doing during the assessment phase

The assessment phase is not a passive waiting period. What you do during it has a direct effect on the outcome of your WCA. The most important tasks are:

Complete and return the ESA50 questionnaire. This is the form on which you describe how your conditions affect each WCA activity. On Universal Credit the equivalent is the UC50 form. Filling it in thoroughly is the single biggest thing within your control - see our guide on how to fill in the ESA50.
Keep sending fit notes. Until you are placed in a group, you usually need to keep providing fit notes from your GP to show you are still unable to work. If your claim is on Universal Credit, the same applies, and our guide to fit notes on Universal Credit explains how and when to submit them.
Gather supporting evidence. Letters from your GP, consultant or community team that link your conditions to specific functional limitations carry real weight. Our evidence checklist walks through what to collect.
Prepare for the assessment itself. You may be asked to take part in a Work Capability Assessment by phone, video or in person. Knowing what to say at your WCA assessment and how a phone assessment works removes much of the stress.

What happens when the assessment phase ends

The assessment phase ends when the DWP makes its decision on your WCA. There are three broad outcomes:

Support Group. You are found to have limited capability for work and limited capability for work-related activity. This is the higher-paying group, and there are no work-related requirements. Our guide on how to qualify for the Support Group explains the descriptors and the substantial-risk route.
Work-Related Activity Group. You are found to have limited capability for work but not for work-related activity, so you receive the smaller component and are expected to take part in some work-focused activity. Our WRAG explainer covers what this involves.
Fit for work. You score fewer than the required points and are found capable of work. This does not add a component, and the assessment-rate ESA usually stops. You can challenge this through mandatory reconsideration - see our guide to a fit-for-work or zero-points decision.

Whichever outcome applies, the assessment rate you were paid during the phase is not taken back. If you move into a higher-paying group, the additional amount is normally backdated to week 14, and our guide to backdating ESA or Universal Credit explains how these arrears are worked out.

The assessment phase on New Style ESA and Universal Credit

The same broad structure applies across the modern system, but the labels differ. New Style ESA is the contribution-based benefit you can claim if you have a sufficient National Insurance record. It is not means-tested, so your savings and a partner's income do not affect it. New Style ESA has an assessment phase with a lower assessment rate for roughly the first 13 weeks, after which the contributory main-phase rate applies once you are placed in a group.

On Universal Credit, the equivalent of the Support Group is being placed in the limited capability for work and work-related activity (LCWRA) group. The LCWRA element is added to your Universal Credit, but importantly it usually starts after a waiting period rather than from the first day of your health claim, which mirrors the role of the assessment phase. Income-related ESA, the old means-tested version, is gradually being moved to Universal Credit through managed migration, so many people will encounter the Universal Credit version of these rules. If you are weighing the two, our pages on ESA versus PIP and on the wider ESA changes coming in 2026 give useful context, and remember that the WCA itself is under DWP reform with changes phasing in from 2025.

The exception: terminal illness

There is one important situation where the assessment phase does not apply in the usual way. If you are nearing the end of life, you can be fast-tracked straight into the Support Group (or the LCWRA group on Universal Credit) without going through a Work Capability Assessment. This is done using the SR1 form, completed by a clinician such as a GP, consultant or specialist nurse. In these cases you are not held on the assessment rate while a WCA is arranged, because no WCA is required.

Managing money during a long wait

Because the assessment phase can stretch well beyond 13 weeks, it is worth thinking ahead about the gap between the assessment rate and the higher rate you may eventually receive. A few practical points:

You can usually claim other support during the assessment phase, such as help with Council Tax or, depending on your circumstances, Universal Credit alongside New Style ESA.
If you also have care or mobility needs, Personal Independence Payment is assessed separately and can be claimed at the same time, because it tests different things to the WCA.
Keep copies of everything you send and note the dates. If a decision is delayed beyond a reasonable period, you can chase the DWP and, if necessary, ask about hardship support.
Remember that any increase from being placed in a group is normally backdated, so a long wait is usually a cash-flow problem rather than a permanent loss.

Frequently Asked Questions

How long does the ESA assessment phase last?

The assessment phase is designed to last roughly the first 13 weeks of your claim, while the DWP carries out the Work Capability Assessment and decides which group you belong in. In practice it often runs longer than 13 weeks because of waiting times for the assessment. You stay on the assessment rate until a decision is made, and if your group is decided after week 13 you should receive backdated arrears.

Why is the assessment rate lower than the main ESA rate?

During the assessment phase the DWP has not yet decided whether you have limited capability for work or which group you should be in, so you are paid a basic assessment rate. Once the Work Capability Assessment is complete and you are placed in the Support Group or Work-Related Activity Group, your payment usually increases to include the relevant component or element. Check GOV.UK for the current weekly figures.

Will I get backdated money after the assessment phase?

Usually yes. If the Work Capability Assessment is decided after the 13-week point and you are placed in a group that pays more, the extra amount is normally backdated to the start of week 14 of your claim. The assessment rate you received in the meantime is not clawed back. If you are found fit for work, no extra component is added.

What happens if my assessment takes longer than 13 weeks?

Assessment waiting times are frequently longer than 13 weeks. If that happens you simply remain on the assessment rate until the DWP makes its decision. You do not move to a higher rate automatically at week 13 - the increase only happens once the Work Capability Assessment confirms you have limited capability for work and places you in a group.

Do I have to do anything during the assessment phase?

You will normally be sent the ESA50 (or UC50 on Universal Credit) questionnaire to complete and return, and you may be asked to attend or take part in a Work Capability Assessment by phone, video or in person. You should also keep sending fit notes from your GP. Completing the questionnaire fully and on time is the single most important thing you can do during the assessment phase.

Does the assessment phase apply to New Style ESA and Universal Credit too?

Yes. New Style ESA has an assessment phase with a lower assessment rate for roughly the first 13 weeks before the contributory main-phase rate applies. On Universal Credit the equivalent is the period before the limited capability for work and work-related activity (LCWRA) element is added, which also typically begins after a waiting period rather than from day one.

Can I be placed in a group before 13 weeks are up?

In most cases the higher rate is not paid before the 13-week point even if the assessment is completed early. The main exception is terminal illness: if you are nearing the end of life, an SR1 form can fast-track you straight into the Support Group without a Work Capability Assessment, and you would not be held on the assessment rate in the normal way.
