NWSSP CoS Team are responsible for issuing a Certificate of Sponsorship (CoS) to all HEIW Appointed Junior Medical and Dental trainees, along with other staff groups in NHS Wales, who require a Skilled Worker CoS in order to commence in post. Those who require sponsorship will be contacted by their Employer to begin the CoS process.

NWSSP CoS Team also assign Certificate of Sponsorships for all eligible staff groups in NHS Wales for certain organisations, some of which may previously have been managed by NWSSP Recruitment Services, provided that an applicant meets all essential criteria. Please see below a list of NHS Organisations in Wales covered by the NWSSP CoS Team:

  • Aneurin Bevan University Health Board
  • Betsi Cadwaladr University Health Board
  • NWSSP – All Wales CoS Licence
  • Powys Teaching Health Board
  • Public Health Wales
  • Velindre University NHS Trust, including:
      • NWSSP
      • DHCW
      • Velindre Cancer Centre
      • Welsh Blood Service
  • Welsh Ambulance Services Trust

Please note: For HEIW Appointed Trainees, the place of work can be anywhere in NHS Wales, including within organisations that may not be listed above.

For HEIW appointed trainees or trainees employed by NWSSP Single Lead Employer, the Skilled Worker Certificate of Sponsorship will cover the duration of the training programme, including all rotations. If you are a Trainee and do not require a CoS for the full duration of your programme, you should inform your Employer. For all other posts, the Recruiting Manager of the post will determine the duration of the CoS and inform NWSSP CoS Team.

Trainees will only have to apply for a new visa when their programme comes to an end, rather than the previous process which required trainees to re-apply every time their employment changed as a result of a change in rotation. This arrangement reduces the associated costs incurred to Medical and Dental Trainees and reduces administrative and associated costs for NHS Organisations in Wales.
