If your workforce carries out work that could disturb asbestos, medical surveillance is not a one-off box to tick. Under the Control of Asbestos Regulations 2012 (CAR 2012), certain workers need a medical before they start and then at regular intervals for as long as they continue that work. Getting the timing wrong can leave your drivers, operatives and contractors unable to work, and can leave your business exposed during an inspection.

This guide explains how often asbestos medicals need to be renewed, which of your workers need one, what the medical involves and how to keep renewals on track across your workforce.

How often do asbestos medicals need to be renewed?

The renewal interval depends on the type of asbestos work your team carries out:

  • Licensed asbestos work: workers must have a medical before they start, then a repeat medical at least every two years. These examinations must be carried out by an HSE-appointed doctor.
  • Notifiable non-licensed work (NNLW): workers must have a medical before they start, then a repeat medical at least every three years while they continue to do this work.
  • Non-licensed work that is not notifiable: there is no requirement under CAR 2012 for medical surveillance, although you still need to assess and control the risk, provide training and use suitable protective equipment.

HSE has reviewed these intervals in the past and decided to keep them as they are, so the two-year and three-year cycles remain the standard your business should plan around.

Can a licensed worker's medical cover non-licensed work?

Yes. A valid medical for licensed work is acceptable for notifiable non-licensed work. It does not work the other way round: a medical carried out for NNLW does not cover someone doing licensed work.

Which of your workers need an asbestos medical?

Your asbestos survey and risk assessment should tell you what kind of work your team is likely to do. As a general guide, medical surveillance applies to people who:

  • remove, repair or disturb asbestos as part of licensed work, such as work with sprayed coatings, most asbestos insulation and asbestos insulating board
  • carry out notifiable non-licensed work, for example removing asbestos materials that have deteriorated or been damaged
  • work in trades where NNLW is a regular part of the job, such as some roofing, maintenance, demolition, refurbishment and building services roles

If you are not sure which category your work falls into, take advice from a competent asbestos professional before the work starts. It is much easier to arrange medicals in advance than to stand a team down mid-project.

What does an asbestos medical involve?

An asbestos medical is focused on your worker's respiratory health. While the exact process can vary, it typically includes:

  • A health and work history questionnaire: covering previous asbestos exposure, smoking history, breathing symptoms and general health.
  • A chest examination: carried out by the doctor to check for signs of respiratory problems.
  • A lung function test (spirometry): your worker blows into a device that measures how much air they can breathe out and how quickly.
  • A discussion of the results: including any advice on reducing exposure and when the next medical is due.

A chest X-ray is not a routine part of the medical. The doctor will only refer for further tests if there is a clinical reason to do so.

Once the medical is complete, ask for written confirmation that the examination took place and keep a copy on file alongside your health records for that employee.

What records do employers need to keep?

For workers doing licensed work or NNLW, CAR 2012 requires employers to keep a health record for each worker, and these records must be kept for 40 years. That long retention period reflects the fact that asbestos-related diseases can take many years to develop.

Good records also make renewals much easier to manage. At a minimum, it helps to track:

  • each worker's name and role
  • the type of asbestos work they carry out
  • the date of their last medical and who carried it out
  • the date their next medical is due
  • exposure records for any work with asbestos

What happens if an asbestos medical lapses?

If a worker's medical runs out, they should not carry out licensed work or NNLW until a new medical has been completed. In practice, a lapsed certificate can mean:

  • delays on site while you rearrange your team
  • problems passing a client's or principal contractor's compliance checks
  • potential enforcement action if an HSE inspector finds gaps in your records

The simplest way to avoid this is to book renewals well before the expiry date rather than waiting until the last week.

How to manage asbestos medical renewals across your workforce

Set reminders early

Add renewal dates to your HR or compliance system and set reminders two to three months ahead. That gives you time to book appointments around site work and shift patterns.

Book in groups

If several of your workers started at the same time, their medicals are likely to fall due together. Booking them as a group helps you plan downtime and keeps everyone's renewal dates aligned.

Check new starters on day one

Ask new starters and subcontractors for evidence of a current asbestos medical before they go on site. If they do not have one, arrange it before they start any asbestos work. You may want to combine this with a pre-employment medical.

Look at the bigger health picture

Asbestos medicals sit within your wider health surveillance duties. Many employers find it more efficient to manage asbestos medicals alongside other checks, such as safety critical medicals for plant operators or general occupational health support.
