Introduction
From 8 April 2026, the Home Office introduced updated pay frequency rules for sponsored Skilled Workers through Appendix Skilled Worker, paragraph SW 14.3B of the Immigration Rules. These changes form part of the government’s broader effort to strengthen sponsorship compliance and to ensure that overseas nationals working in the UK under a Skilled Worker visa receive their salary in a regular, verifiable, and auditable manner.
It is important to note at the outset that these rules are not a general labour law reform affecting all UK workers. They are immigration compliance obligations that apply specifically to UK Visas and Immigration (UKVI) licence holders who sponsor Skilled Workers – and to the sponsored workers themselves. General employees employed by non-sponsoring employers are not within the scope of this framework.
This guide explains the new rules in full, covers the key technical detail on salary averaging windows, explains how compliance is monitored through the Sponsor Management System (SMS) and Real Time Information (RTI) payroll submissions, and addresses the consequences of non-compliance.
1. Background and policy context
The Skilled Worker route, introduced in December 2020 as a successor to Tier 2 (General), requires that sponsored workers be paid at or above a defined salary threshold – currently the higher of the general minimum salary, the going rate for the occupation, or the new entrant rate where applicable. The Home Office’s ability to verify ongoing salary compliance has historically depended on a combination of sponsor reporting duties, RTI data from HMRC, and periodic compliance visits.
However, a pattern of concern emerged from compliance intelligence gathered between 2022 and 2025. A minority of sponsors β particularly in sectors such as health and social care, hospitality, and construction – were found to be paying sponsored workers in irregular lump sums, making it difficult for UKVI to assess whether the worker was genuinely being paid at the sponsored rate on a sustained basis. In some cases, irregular payments concealed effective rates of pay that fell below the minimum threshold, particularly when bonuses, expenses, or one-off payments were included to inflate apparent earnings.
The revisions introduced through SW 14.3B are a direct policy response to these findings. They impose a clearer structure on how sponsors must pay sponsored workers and over what periods salary compliance is assessed.
2. Who the rules apply to
The obligations under Appendix SW 14.3B apply to:
- UK employers holding a valid Skilled Worker sponsor licence issued by UKVI
- Those employers’ sponsored workers holding leave under the Skilled Worker route
- Employers in the process of sponsoring a new Skilled Worker where the Certificate of Sponsorship (CoS) is assigned on or after 8 April 2026
Sponsors who assigned a CoS before 8 April 2026 under the previous rules should note that the averaging provisions (see Section 4 below) will apply to any salary compliance assessment conducted on or after that date, even where the underlying visa predates the rule change.
The rules do not apply to workers on other visa routes (such as Global Talent, Graduate, or Start-up), nor to workers employed without any visa requirement (such as British citizens or those with settled status). They also do not apply to employers who do not hold a sponsor licence, regardless of the nationality or immigration status of their workforce.
3. The pay frequency requirement under SW 14.3B
3.1 The core obligation
Under SW 14.3B, sponsors must pay their Skilled Workers at the salary stated on the Certificate of Sponsorship at a frequency that is at least monthly, or as stated in the worker’s contract of employment. There is no mandatory fortnightly payment requirement for lower earners or any other earnings band. The framework establishes monthly payment as the minimum acceptable frequency; more frequent payment (weekly or fortnightly) is entirely permissible.
The requirement is deliberately straightforward in structure: salary must flow regularly, must be traceable through PAYE and RTI records, and must not be deferred, accumulated, or structured in a way that obscures the effective rate of pay.
Key point – no fortnightly requirement: Earlier commentary on these rules incorrectly stated that workers earning below the National Living Wage must be paid fortnightly. This is not accurate. SW 14.3B requires payment at least monthly (or per the contract). There is no mandatory fortnightly rule for any category of sponsored worker.
3.2 What counts as salary for compliance purposes
For the purpose of assessing whether the sponsored salary threshold is met, sponsors may include only those elements of pay that qualify under the Home Office’s existing rules. Qualifying elements include basic salary, guaranteed allowances (such as a London weighting that is contractual and non-discretionary), and any other fixed element that the sponsor has declared on the CoS.
The following elements do not count towards the sponsored salary threshold and cannot be used to make up any shortfall:
- Discretionary bonuses or commission
- Tips or gratuities
- Overtime pay (unless guaranteed)
- Expenses or expense allowances
- Benefits in kind (including accommodation, meals, or transport)
4. Salary averaging windows – the critical technical detail
One of the most significant and technically important aspects of the 2026 update is the introduction of formal averaging windows for salary compliance assessment. This is the area most commonly overlooked in summaries of the new rules, and it has direct practical implications for sponsors whose workers are on variable hours, shift patterns, or annualised salary arrangements.
The Home Office now assesses whether a sponsored worker is being paid at the required salary threshold by reference to the average earnings over a defined reference period. The applicable window depends on how frequently the worker is paid:
| Pay frequency | Averaging window |
|---|---|
| Monthly | 3 months |
| More frequent than monthly (weekly/fortnightly) | 12 weeks |
| Irregular working patterns | 17 weeks |
4.1 Three-month averaging window (monthly-paid workers)
For workers paid monthly, the Home Office will assess salary compliance by looking at the worker’s average monthly earnings over the three most recent consecutive months for which payroll data is available. If the average over those three months meets or exceeds the required annual salary expressed as a monthly figure, the worker will be considered compliant for that period.
This means that a worker who earns slightly more in one month and slightly less in another – for example, because of approved unpaid leave or a shift in their working pattern – will not automatically fall below the threshold, provided the three-month average is maintained. Sponsors should nonetheless ensure that no individual monthly payment falls more than marginally below the threshold without a recorded, legitimate reason.
4.2 Twelve-week averaging window (workers paid more frequently than monthly)
For workers paid weekly or fortnightly, the relevant reference period is 12 weeks. The Home Office will calculate the total earnings over the 12 most recent consecutive weeks and assess whether the annualised equivalent (by dividing the total by 12 and multiplying by 52) meets the required salary.
This provision is particularly relevant in sectors such as healthcare and retail where shift-based or rota-based pay structures are common. Sponsors in these sectors should build systems to monitor rolling 12-week averages as part of their ongoing payroll governance.
4.3 Seventeen-week averaging window (irregular working patterns)
For workers on irregular working patterns – such as those engaged on annualised hours contracts, term-time working arrangements, or highly variable shift patterns – a 17-week averaging window applies. This extended window provides greater flexibility to capture periods where earnings are structurally low (such as school holidays for a term-time worker) alongside higher-earning periods.
Sponsors who engage Skilled Workers under these arrangements should document the working pattern clearly in the employment contract, and should retain payroll records over rolling 17-week periods to support any compliance audit or UKVI inquiry.
4.4 Practical implications of the averaging rules
- A single month or week of lower earnings does not automatically trigger a sponsorship breach, provided the relevant averaging window is satisfied.
- Sponsors should actively monitor rolling averages – not just point-in-time pay – as part of their sponsorship compliance programme.
- Where a sponsored worker takes unpaid leave, is placed on reduced hours, or has a change in working pattern, sponsors should model the effect on the applicable averaging window and take corrective action before a breach crystallises.
- Sponsors should ensure their payroll systems can generate the relevant averaging calculations on request, as UKVI may ask for this data during a compliance visit.
5. Compliance mechanisms: SMS duties and RTI
Crucially, there is no new standalone registration portal or “Pay Schedule Registration” process under the 2026 changes. Salary compliance is monitored and enforced through the mechanisms that already exist – the Sponsor Management System and HMRC’s Real Time Information payroll reporting.
5.1 Sponsor Management System (SMS) duties
Sponsors must report via the SMS within ten working days if any of the following occur:
- The sponsored worker’s salary changes to a level below the rate stated on the CoS
- The worker is placed on unpaid leave for more than four weeks in any 12-month period
- The worker’s hours or working pattern change materially
- The worker is temporarily absent in circumstances that may affect their pay record
Failure to make timely reports via the SMS is itself a breach of sponsor duties, independent of whether an underlying salary shortfall has occurred.
5.2 RTI and HMRC data sharing
The Home Office and HMRC share data routinely under a memorandum of understanding. RTI submissions are cross-referenced against CoS data to identify sponsored workers whose reported earnings appear inconsistent with their sponsored salary. Discrepancies identified through this data-matching process may trigger a UKVI compliance inquiry or prompt further investigation.
5.3 No new civil penalty for pay schedule registration
Several commentaries on the 2026 changes have incorrectly referred to a requirement to “register” pay schedules with a government body by 31 March 2026, with a suggested fine of Β£500 for non-registration. There is no such obligation under the actual Immigration Rules or associated Home Office guidance. The civil penalty figures that appear in enforcement contexts relate to the existing civil penalty regime for employing illegal workers or for serious sponsorship breaches β they are not specific to a pay frequency registration requirement.
6. Consequences of non-compliance
6.1 Sponsor licence action
The Home Office may take action against the sponsor’s licence where a pattern of pay non-compliance is identified. Possible actions range from a formal warning, through a downgrade to a B-rated licence (with an associated action plan and monitoring period), to full licence revocation in the most serious cases. Where a licence is revoked, all sponsored workers must either leave the UK, find a new sponsor, or switch to an eligible alternative visa route within 60 days.
6.2 Curtailment of sponsored workers’ leave
Where a sponsored worker is found to be paid below the required threshold (taking into account the applicable averaging window), the Home Office may curtail the worker’s leave to remain. This creates serious consequences for the worker and potential unfair dismissal and reputational risks for the employer.
6.3 Civil penalties for illegal working
If non-compliance with pay frequency rules is associated with a broader failure of sponsorship duties, the existing civil penalty regime for illegal working may apply. Civil penalties under the Immigration, Asylum and Nationality Act 2006 (as amended) can reach up to Β£20,000 per worker for a first breach, and up to Β£60,000 for repeat breaches.
6.4 Criminal liability
Knowing facilitation of immigration irregularities can attract criminal liability under section 21 of the Immigration, Asylum and Nationality Act 2006, with a maximum sentence of five years’ imprisonment.
7. Practical compliance steps for sponsors
- Audit all sponsored workers’ pay arrangements: confirm that every Skilled Worker is paid at least monthly and at the salary stated on their CoS.
- Identify the applicable averaging window: for each sponsored worker, determine whether the 3-month, 12-week, or 17-week window applies, and set up payroll monitoring accordingly.
- Update employment contracts: ensure that pay frequency is stated clearly and is consistent with the CoS.
- Review payroll software: confirm your system can generate rolling average calculations for each sponsored worker across the relevant reference period.
- Check RTI alignment: verify that worker payroll records align with the details held in the SMS.
- Train HR and payroll teams: ensure staff who manage sponsored worker payroll understand the averaging rules and reporting obligations.
- Document any changes promptly: where a sponsored worker’s hours, pay, or working pattern changes, update the SMS within ten working days.
- Seek specialist advice: for complex pay structures (annualised hours, term-time working, or output-based pay), obtain specialist immigration and employment law advice to model the effect on salary compliance.
8. Interaction with employment law
National Minimum Wage and National Living Wage
Sponsored Skilled Workers are entitled to the National Minimum Wage or National Living Wage in the same way as any other worker. The salary threshold under the Skilled Worker route is set by immigration rules and is separate from the statutory minimum wage, though in practice the sponsored salary will almost always exceed it. The introduction of averaging windows does not affect minimum wage compliance, which must be assessed in accordance with the National Minimum Wage Regulations 2015.
Equality Act 2010
Sponsors should ensure that pay frequency practices do not give rise to indirect discrimination. Where a particular arrangement disproportionately disadvantages workers sharing a protected characteristic, it must be objectively justified.
Employment contract and breach of contract
The sponsored salary stated on the CoS must be consistent with the worker’s written employment contract. Where a sponsor pays below the contracted salary – including in a way that reduces the rolling average below the threshold – this may simultaneously constitute a breach of the immigration rules and a breach of contract, giving rise to potential Employment Tribunal claims.
Conclusion
The 2026 changes to Skilled Worker pay frequency requirements – centred on Appendix SW 14.3B – represent a meaningful tightening of sponsorship compliance obligations. The core message for sponsors is straightforward: pay your sponsored workers at least monthly at the salary stated on their Certificate of Sponsorship, ensure your payroll records are accurate and aligned with your SMS records, and understand which averaging window applies to each worker so that you can monitor ongoing compliance with confidence.
The introduction of the 3-month, 12-week, and 17-week averaging windows is a nuanced but important development that gives sponsors some flexibility to accommodate natural variation in earnings – but also requires active monitoring rather than a passive assumption of compliance.
