UK Sponsor Licence Services by Immigration Law Specialists

A UK sponsor licence is permission from the Home Office for a UK employer to sponsor workers from outside the UK. Conroy Baker Ltd advises employers on applications, sponsor duties, suspension, revocation and the steps that follow a Home Office decision. Under current guidance most licences no longer need renewal, but they can still be suspended or revoked, so good compliance is what protects them.

If you are applying for the first time, managing an existing licence or responding to Home Office action, Conroy Baker gives you a clear route and a named adviser from the first call.

• Renewal: not required. Licences are valid indefinitely unless revoked or surrendered, except UK Expansion Worker and Scale-up licences (maximum 4 years). GOV.UK Part 1
• Refusal: no right of appeal. An error correction request must be made within 14 calendar days of the refusal letter. GOV.UK Part 1
• Cooling-off: 6 months after refusal, 12 months after a first revocation or a surrender during compliance action, 24 months if repeated. GOV.UK Part 1
• Suspension: no new Certificates of Sponsorship and 20 working days to respond in writing. GOV.UK Part 3
• Revocation: no right of appeal. Sponsored workers normally have permission curtailed to 60 calendar days. GOV.UK Part 3

UK Sponsor Licence management involves a strict application process, ongoing compliance duties, and real risk if either is handled poorly. Conroy Baker’s Immigration Law Specialists work across the full range of sponsor licence services, from a first application through to complex compliance challenges – giving employers clear, practical guidance at every stage.

A refusal or revocation is serious, and the options are narrower than many employers expect. Conroy Baker explains what the guidance allows before you spend time on a route that does not exist.

There is no right of appeal. If you believe the Home Office made a mistake, you can submit an error correction request within 14 calendar days of the date on the refusal letter. A new application made during the cooling-off period is automatically refused, so timing matters. See the cooling-off periods.

You cannot assign new Certificates of Sponsorship, and you normally have 20 working days to respond in writing. Existing workers with valid permission are not affected unless the licence is revoked.

There is no right of appeal. Certificates of Sponsorship are invalidated, sponsored workers normally have their permission curtailed to 60 calendar days, and a cooling-off period of at least 12 months applies before you can apply again. Conroy Baker can help you plan for affected workers and prepare for a future application. Read about revocation.

UK Sponsor Licence regulations are strict, and the stakes are high – non-compliance can mean serious penalties and disruption to your workforce. Conroy Baker’s Immigration Law Specialists take a holistic, client-focused approach across the full range of sponsor licence work.
