Skilled Worker · Additional employment

Can a Skilled Worker take a second job or run a business?

The 20-hour allowance is not a general right to take any side job. The work, occupation, timing and continuing sponsored role must fit the supplementary-employment conditions, or a second Certificate of Sponsorship and approved application may be required.

Rules and sponsor guidance checked 1 October 2026

Twenty hours is a ceiling, not the complete permission.

This analysis applies to ordinary Skilled Worker supplementary employment under the Rules and sponsor guidance in force on 1 October 2026. A separate relaxation due to commence on 8 October 2026 for certain recognised victims of modern slavery is outside this general framework and requires its own assessment.

The position

A second job is possible only inside the supplementary-employment conditions

A Skilled Worker can normally work up to 20 hours a week in a second job or their own business without a second Certificate of Sponsorship if they continue the sponsored job, do the additional work outside their contracted sponsored hours and the work is in an eligible higher-skilled occupation, on the Immigration Salary List, or in the same profession and at the same professional level as the sponsored job. The second employer need not hold a sponsor licence, but must complete a right to work check. Work outside those conditions usually requires a second sponsor, a new Certificate of Sponsorship and permission before it starts.

  • Count the additional work and business administration within the 20-hour weekly ceiling.
  • A medium-skilled occupation is available only under the stated pre-22 July 2025 transitional protection.
  • Overtime in the sponsored job, supplementary employment and a second sponsored job are 3 different categories.

The phrase ‘20-hour rule’ is deceptively simple. It can describe a lawful second employment, consultancy or small business. It can also conceal work in an ineligible occupation, hours performed during the sponsored job, a de facto move to another employer or a business whose administration takes the worker beyond the permitted ceiling.

The decision should not begin with the weekly total. It should begin with the person's current permission, the sponsored job that must continue and the actual work proposed. Only then can the supplementary role be classified against the current occupation tables, Immigration Salary List or same-profession test.

That discipline protects all 3 parties. The worker avoids a breach of conditions. The supplementary employer can establish a statutory excuse and understand the restriction. The principal sponsor can manage conflicts, attendance and the continuing truth of the job for which it remains responsible without inventing a Home Office approval process that the guidance does not require.

01 / Classify the work

Overtime, supplementary employment and secondary employment are not the same.

Overtime is additional time worked in the job for which the person is sponsored. Current GOV.UK guidance states that it does not require a visa update and does not impose a separate immigration limit on the number of overtime hours. Employment law, contract, health and safety and working-time controls continue to apply.

Supplementary employment is additional paid work undertaken alongside the sponsored job. It can be with another employer or, under the current public guidance, in the worker's own business. It does not require a second sponsor or Home Office notification if every supplementary-employment condition is met.

Secondary employment is the Home Office term for a second job which is not confined to the supplementary-employment allowance. It requires a licensed second sponsor, a valid Certificate of Sponsorship and an approved application adding the second job. The worker must not start that second sponsored role merely because an application has been prepared or submitted.

Overtime

More hours in the sponsored job. No separate immigration hours cap, but the sponsored employment and wider employment-law controls remain.

Supplementary employment

No more than 20 hours a week, outside sponsored hours, while the sponsored job continues and the additional work meets an eligible category.

Secondary employment

A separately sponsored second job supported by a second CoS and approved permission, used where the supplementary conditions do not cover the proposal.

02 / The hours ceiling

The 20 hours attach to the additional work, not to each contract separately.

The sponsor guidance states that supplementary employment must be for no more than 20 hours a week and must take place outside the hours when the worker is contracted to work for the principal sponsor. The safe analysis is therefore of the total additional activity, not a separate 20-hour allowance for each second employer, client or business.

A worker with 2 supplementary engagements should record the combined hours. Variable hours, on-call commitments and work spread across a billing cycle need an intelligible weekly account. A contract promising 10 hours is not sufficient where the actual work regularly requires more.

The additional work cannot displace the sponsored role. Evening or weekend work may fit; work undertaken during the hours allocated to the sponsor does not become supplementary merely because it is performed remotely or invoiced through a separate company. The principal sponsored job must remain genuine and continue in substance.

03 / The occupation test

A second job can be under 20 hours and still be prohibited.

For a Skilled Worker, the current sponsor guidance permits supplementary employment in a job within an eligible SOC 2020 occupation listed in Table 1, 2 or 3 of Appendix Skilled Occupations. Those are the higher-skilled tables used by the current route. The additional work can also qualify if it is in an occupation on the Immigration Salary List when the work begins, or is in the same profession and at the same professional level as the sponsored work.

The occupation code must follow the actual duties. A prestigious title, professional employer or high hourly rate does not turn an ineligible activity into higher-skilled work. Equally, the job does not need to repeat the principal sponsor's exact occupation code if it independently falls within a permitted table.

The same-profession route should be used with precision. Similar industry, transferable skills or the same broad sector do not necessarily establish the same profession and professional level. Record the core duties, responsibility and level on both sides before treating that alternative as satisfied.

04 / Transitional protection

Medium-skilled work depends on the worker's pre-22 July 2025 history.

The 22 July 2025 changes narrowed the ordinary Skilled Worker skill threshold. Current guidance preserves access to specified medium-skilled occupations for a person whose first Tier 2 or Skilled Worker Certificate of Sponsorship was issued before 22 July 2025 and who has held continuous Skilled Worker permission since then.

For supplementary employment, the sponsor guidance identifies the corresponding transitional occupation tables. A worker granted under the later Rules should not assume that an occupation qualifies merely because it appeared on an older eligible-occupation list or is described online as Skilled Worker work.

The evidence should establish the first relevant CoS date, each grant of permission and continuity. Where that history is incomplete or an intervening route breaks the stated condition, the additional work should be tested under the current higher-skilled, Immigration Salary List or same-profession alternatives instead.

05 / Business and consultancy

Owning a company is not the same as working lawfully in it.

GOV.UK expressly recognises that a Skilled Worker may work for their own business within the supplementary-employment allowance. That does not remove the occupation and hours conditions. The actual services must be eligible, the sponsored job must continue and all work must sit outside the sponsored hours.

Business administration counts. Preparing invoices, marketing, client calls, bookkeeping, product work and delivery cannot be separated artificially so that only billable hours appear beneath 20. A director may also have company-law, tax, regulatory and contractual responsibilities which require advice outside immigration law.

A consultancy label does not answer whether the work is eligible. Define each service, the professional level, the clients, delivery hours and administrative time. If the business is in substance becoming the person's main occupation or the work cannot be classified within the supplementary conditions, another immigration structure is required.

06 / The 2 employers

The second employer needs evidence; the principal sponsor retains its own duties.

Sponsor guidance states that supplementary employment does not have to be with a licensed sponsor and need not be reported to the Home Office when it meets the criteria. The supplementary employer must nevertheless carry out the prescribed right to work check before employment begins and understand the restrictions that make the work lawful.

A sensible file records the online right to work result, current permission expiry, principal sponsored hours, proposed supplementary hours, duties, occupation analysis and the basis on which the work qualifies. The employer should not rely on the worker's assurance that the job is ‘only 20 hours’ where the job itself is ineligible.

The principal sponsor does not become responsible for supervising the second employer. It remains responsible for the sponsored job, attendance, salary, reporting and the accuracy of the role it sponsors. Its employment contract may require consent to outside work or address confidentiality and conflict issues. That contractual process should not be confused with a Home Office permission requirement.

07 / When the allowance is not enough

More than 20 hours or an ineligible job requires a different permission analysis.

Where a second job exceeds 20 paid hours a week, the current public guidance requires the worker to update their permission. Sponsor guidance describes this as secondary employment: the second employer must hold the relevant licence, assign a new CoS and sponsor a job meeting the route requirements.

The application must explain that the worker seeks permission for both jobs and identify the current CoS and permission expiry. The second job needs its own eligible occupation, salary, hours and sponsorship assessment. The fact that the main job already satisfies Skilled Worker does not relax those requirements for the second role.

The worker can ordinarily continue the existing sponsored job while the application is pending but should not start the new secondary employment until permission has been granted. Travel while an in-country application is outstanding can withdraw it. The start date, notice obligations and any dependant applications should therefore be sequenced before the second employer commits to work.

08 / Historic work

An hours or occupation mistake should be reconstructed before the next application.

Work outside the supplementary conditions without the required permission is a breach of the worker's conditions. It can affect an extension, change-of-employment or settlement application and expose the additional employer if the right to work check did not provide a statutory excuse for the work actually undertaken.

The first task is a chronology: dates, employers or clients, duties, weekly hours, sponsored hours, invoices and pay. Do not retrospectively rename the work or delete business records. Establish what happened, whether any transitional provision applied and when the activity stopped or changed.

Remediation may involve ending or restructuring the additional work, obtaining separate sponsorship, correcting employer controls and addressing the history candidly in a later application. The correct step depends on the scale and duration of the issue, the worker's present permission and the next immigration decision. There is no general assurance that later compliance erases an earlier breach.

Additional-work decision framework

Test the job before the first shift or invoice.

The employer and worker should be able to evidence each step without relying on the phrase ‘20-hour rule’ as the conclusion.

01

Verify the permission

Check the current Skilled Worker grant, expiry, principal sponsor and any transitional pre-22 July 2025 history.

02

Define the work

Write the actual duties, professional level, employer or clients, work pattern and every administrative task.

03

Classify the occupation

Match the role to the current occupation tables, Immigration Salary List or same-profession and level alternative.

04

Map the hours

Keep all supplementary work within 20 hours a week and outside the contracted sponsored hours while the principal job continues.

05

Complete employer controls

Carry out the right to work check, retain the restrictions analysis and resolve contractual consent or conflicts.

06

Escalate when needed

If the proposal falls outside the allowance, obtain a second CoS and approved permission before the secondary job starts.

Practical questions.

Can a Skilled Worker work 20 hours for each of 2 second employers?

The sponsor guidance limits supplementary employment to no more than 20 hours a week. The prudent reading is a combined ceiling across the additional work, not a fresh 20-hour allowance for each employer, client or business.

Does the second employer need a sponsor licence?

Not where the work genuinely meets every supplementary-employment condition. The second employer must still carry out a right to work check. If the job needs to be added as secondary employment, the second employer must hold the relevant sponsor licence and assign a CoS.

Does a Skilled Worker need to tell the Home Office about a second job?

Sponsor guidance states that supplementary employment meeting the criteria does not need to be reported. A second sponsored job outside that allowance requires a permission application. Contractual disclosure to the principal employer is a separate question.

Can a Skilled Worker be self-employed or set up a company?

Potentially. GOV.UK permits work for the person's own business within the 20-hour supplementary allowance. The work must still be eligible, remain outside sponsored hours and include administration when hours are counted. Company ownership alone is not permission to perform unrestricted work.

Can the second job be in a different occupation code?

Yes, if the actual job falls within an eligible higher-skilled occupation table, is on the Immigration Salary List, or independently meets another permitted supplementary category. It need not repeat the principal code, but it must be correctly classified.

Can a Skilled Worker start a second sponsored job while the application is pending?

The worker can normally continue the existing job, but should not start the new secondary employment until the application adding that job has been granted. The second sponsor should align the CoS and start date with that restriction.

Is overtime included in the 20 hours?

Overtime in the job for which the person is sponsored is treated separately. GOV.UK states there is no immigration limit on overtime hours in that sponsored job. Additional work for another employer or the worker's own business is subject to the supplementary conditions.

The 20-hour figure is the last line of the analysis, not the first. A defensible arrangement identifies the actual work, qualifies the occupation, keeps every additional hour outside the sponsored schedule and preserves the sponsored job. Where any of those conditions fail, the answer is not to rename the work: it is to obtain the sponsorship and permission the second role requires before it begins.

Follow the sponsor position from licence to continuing control.

Applications, sponsored roles, reporting, payroll and inspection readiness form one regulatory system. Continue with the part of that system that determines the present risk.
