Waiting for a Scan in Wales: The 8-Week Diagnostic Target Explained, and Your Options

Most of what is written about NHS scan waits is about England. The figures, the targets and the headlines usually come from NHS England. If you live in Wales, none of that applies directly to you. NHS Wales is run by the Welsh Government, publishes its own statistics, and measures diagnostic waits against its own target.

This guide explains the Welsh figures published on 22 October 2026, what the 8-week target means, how to find out where you stand, and what your options are if the wait is longer than you can manage.

What the latest Welsh figures say

On 22 October 2026 the Welsh Government published its NHS activity and performance summary for August and September 2026. In his response to the data, the Cabinet Minister for Health and Care, Mabon ap Gwynfor, said the number of diagnostic pathways waiting fell to just over 111,600 in August, the lowest figure since September 2024.

The previous summary, covering June and July 2026 and published on 20 August, gives the fuller picture. The Welsh Government reported just under 120,300 diagnostic patient pathways waiting at the end of June, of which just over 39,100 had been waiting more than 8 weeks, and a median wait of 5.3 weeks. It also showed wide variation between health boards: Cardiff and Vale had the highest proportion of diagnostic waits over 8 weeks, at 45.5 per cent, and Powys the lowest, at 7.1 per cent. The total has come down since the summer, but a large share of people still wait longer than the target, and where you live makes a real difference.

What the 8-week target is

The Welsh Government's performance summary states that the maximum wait for access to specified diagnostic tests is 8 weeks. The planned care recovery plan set a target date of spring 2024 to reach that standard, and the summary notes that many targets were set by the previous government and that no changes have been confirmed. Senedd Research, in its May 2026 review, said the 8-week diagnostic target had not been restored by March 2026.

Two things are worth knowing about how the target works. It counts pathways, not people, so if you are waiting for two tests you appear twice. And Welsh figures are not collected in the same way as England's, so a Welsh figure cannot be compared directly with an English one. Our guide to NHS MRI waiting times explains the English numbers; this one stays with Wales.

Finding out where you are in the queue

The statistics describe Wales and your health board, not your scan. For that, ask the clinician who referred you and the radiology department you were referred to: how long the current wait is for your type of scan, whether another site within the health board has a shorter list, and whether your referral is marked urgent or routine. If your symptoms have changed since you were referred, tell the referrer, because the urgency of a request can be reviewed.

Senedd Research also points out that the Welsh figures reflect NHS Wales activity only and may not capture patients referred for treatment outside Wales, for example to NHS trusts in England. If you live near the border, it is reasonable to ask whether that is an option.

Your options while you wait

Staying on the NHS list is the right choice for most people, and having a private scan does not by itself take you off it; tell the clinician who referred you what you have done so your pathway can be updated. If the wait is affecting your work, your sleep or your peace of mind, there are three things you can do.

Ask about the whole health board. Waits differ between hospitals within the same board, and a referral can sometimes be moved to a site with a shorter list.

Consider a private scan for the diagnostic step only. The NHS says an MRI scan takes detailed pictures of the inside of your body and is used to help find the cause of symptoms and plan treatment. Many private clinics accept self-referral for MRI and ultrasound; CT and X-ray use ionising radiation and need a referral from a registered healthcare professional. Our guide to private MRI without a GP referral explains the difference.

Take the report back to your GP. A private scan gives you a written report, and your GP can use it to decide what happens next within the NHS, so ask the clinic to send a copy to your GP as well as to you. See how to get your scan images and report.

Private clinics in Wales are regulated differently

In England, private clinics are registered with the Care Quality Commission. That is not the regulator in Wales. GOV.UK states that to run an independent health care service such as a private hospital or clinic, you need to register with the Care Quality Commission in England or with Healthcare Inspectorate Wales in Wales. HIW describes itself as the independent regulator of healthcare and the inspectorate for NHS services in Wales, and its website lets you search for a service and find its inspection reports.

So if you are comparing a clinic in Cardiff with one in Bristol or Liverpool, check the Cardiff clinic on the HIW site and the English clinics on the CQC site. Both are free and take a minute.

When waiting is not the right call

A scan waiting list is for people whose condition is stable enough to wait. If your symptoms are getting worse, go back to the clinician who referred you rather than straight to a private clinic. The NHS says NHS 111 can help if you think you need medical help right now, and that 999 is for life-threatening emergencies like serious road traffic accidents, strokes and heart attacks. A scan appointment is not an emergency service.

Comparing clinics on FindScan

FindScan has city pages for Cardiff and for English cities within reach of much of Wales, such as Bristol and Liverpool. You can compare MRI clinics in Cardiff, ultrasound clinics in Cardiff or search by town, then send an enquiry; the clinic contacts you to confirm whether it needs a referral and the next steps.

FindScan is a directory of independent, regulated imaging clinics: you compare clinics and send an enquiry, and the clinic contacts you. We are not a healthcare provider and nothing here replaces advice from your GP or the clinician who referred you. If you are unsure whether to wait or go private, that conversation is the place to start.
