The UK immigration landscape for sponsored workers changed significantly on 8 April 2026. Following the 5 March 2026 Statement of Changes to the Immigration Rules (HC 1691), the Home Office has introduced a new pay period compliance framework for the Skilled Worker visa route. This amendment has inserted paragraph SW 14.3B into Appendix Skilled Worker, fundamentally alters how salary compliance is assessed for sponsored workers The focus has shifted from an annual salary figure to a granular pay-period-by-pay-period examination.
For HR professionals, payroll teams, and sponsorship licence holders, understanding these changes is critical. Non-compliance could result in visa refusals, adverse findings during Home Office audits, or, in serious cases, action against a sponsor licence.
What Is the Pay Period Rule Change?
Before 8 April 2026, salary compliance for Skilled Worker visa holders was assessed primarily by reference to the annual salary figure stated on the Certificate of Sponsorship (CoS) and the worker’s employment contract. Provided the annual earnings met the relevant salary threshold or occupation going rate, variations in month-to-month pay were generally not an obstacle to compliance.
The March 2026 amendments introduced a significant shift. A new provision, paragraph SW 14.3B, has been inserted into Appendix Skilled Worker of the Immigration Rules and took effect on 8 April 2026. Under this framework, the Home Office can now scrutinise salary not just at an annual level, but across defined pay periods within the sponsorship duration. Payroll records, payslips and working hours data are all relevant to the compliance assessment process.
In practical terms, this means that salary shortfalls occurring during specific pay cycles cannot simply be corrected by higher payments at a later date. The new rules establish measurable thresholds for each pay period, making the distribution of pay across the year a matter of direct immigration concern.
Example: A consultancy sponsors an IT business analyst (SOC 2133) under Table 1 at an annual salary of £54,900, paid monthly at £4,575, exactly the going rate. Due to a payroll processing error, the worker receives only £4,100 in September. The sponsor corrects the underpayment in October, paying £5,050. The annual salary remains on track. Under SW 14.3B(a), the September payment must independently satisfy the going rate for every hour worked that month. At 37.5 hours per week, the worker completes approximately 162.5 hours during September. The going rate for those hours is £4,574 (162.5 × £28.15). The £4,100 actually paid falls £474 short, a pay-period compliance failure. The corrective payment of £5,050 in October does not retrospectively cure the September shortfall. Because the worker’s salary is set at exactly the going rate with no headroom, even a minor payroll error of £474 creates an immediate compliance failure that cannot be recovered within that pay period.
What the New Pay Period Framework Requires
Under paragraph SW 14.3B, sponsored workers must be paid at least monthly, or in accordance with the payment schedule set out in their employment contract. Beyond this basic requirement, the framework introduces specific compliance thresholds that apply across defined payroll periods.
A critical point for sponsors to understand is that SW 14.3B contains two distinct requirements that operate together, not as alternatives. First, under SW 14.3B(a), the salary paid in each individual pay period must equal or exceed the going rate for every hour worked in that period. Second, under SW 14.3B(b) and (c), the salary paid across defined averaging windows must meet the applicable fraction of the annual salary. Both tests must be satisfied. Meeting the averaging threshold alone does not excuse a pay period in which the going rate for the hours actually worked was not met.
- Per Pay Period Salary Assessment
Under SW 14.3B (a), caseworkers can assess whether salary paid during any given pay period corresponds with the applicable going rate for the hours worked during that period. This means that a shortfall in any particular month or payroll cycle may constitute a compliance issue, even if the annual salary total would otherwise appear to meet the required threshold.
Examples:
Compliant:
A construction firm sponsors a civil engineer (SOC 2121) under Table 1 at an annual salary of £68,000, paid monthly at approximately £5,667. The going rate for this role is £50,400 per year (£25.85 per hour based on 37.5 hours per week). During a critical project phase, the engineer works 45 hours per week for an entire month to meet a site handover deadline but continues to receive the standard monthly salary of £5,667. Under SW 14.3B(a), the going rate test applies to the hours actually worked. At 45 hours per week over approximately 4.3 weeks, the engineer works roughly 195 hours that month. The going rate for those hours is approximately £5,041 (195 × £25.85).
The £5,667 actually paid exceeds this by £626: the per-period going rate test is comfortably satisfied because the worker’s salary sits well above the occupation going rate. The three-month averaging test under SW 14.3B(b)(i) requires the total salary paid over any three-month period to equal at least a quarter of the annual salary of £68,000, which is £17,000. Across three standard months the worker receives £17,001, clearing the threshold.
Both tests pass. The margin above the going rate is what protects this sponsor on the per-period test: a worker paid at exactly £50,400 in the same overtime scenario would receive only £4,200 per month: £841 short of the £5,041 the going rate requires for the hours actually worked.
Non-Compliant:
By contrast, a consultancy sponsors an IT business analyst (SOC 2133) at exactly the going rate of £54,900, paid monthly at £4,575. A payroll processing error in September reduces that month’s payment to £4,100. The going rate for 162.5 hours worked that month is £4,574 (162.5 × £28.15). The £4,100 actually paid falls £474 short.
This is a pay-period compliance failure under SW 14.3B(a), and the corrective payment in October does not retrospectively cure it. The difference between the two examples is straightforward: the civil engineer’s salary sits £17,600 above the going rate, providing headroom to absorb the overtime period. The IT business analyst’s salary sits at the going rate with no margin, meaning even a minor payroll error triggers a failure.
- Three-Month Averaging for Monthly-Paid Workers
Where a sponsored worker is paid monthly or less frequently than monthly, salary compliance is assessed over a rolling three-month period. Over any such period, the total salary paid must amount to at least one quarter (25%) of the required annual salary for the sponsored role. Workers paid more frequently than monthly, for example, weekly or fortnightly, fall under the separate twelve-week averaging rule described below. This distinction is a hard boundary under the Rules; monthly-paid workers sit firmly within the three-month bracket and cannot be assessed under the twelve-week provision.
- Twelve-Week Averaging for More Frequently Paid Workers
Where a sponsored worker is paid more frequently than monthly, for example, weekly or fortnightly, the applicable averaging window is twelve weeks. The total salary paid across any twelve-week period must equal at least 12/52 of the applicable annual salary requirement for the role.
Example (compliant): A CQC-registered domiciliary care provider sponsors a care worker (SOC 6135) under the Immigration Salary List at £25,000 per year (£12.82 per hour), paid weekly. The worker’s hours fluctuate with client demand. Over a twelve-week period, the worker completes 43 hours per week during eight busy weeks (covering for a colleague on leave) and 28 hours per week during four quieter weeks (when several regular clients are temporarily admitted to hospital). The per-period going rate test under SW 14.3B(a) is met in every individual week, the worker is paid £12.82 for every hour worked, so the hourly rate is satisfied regardless of whether the week is busy or quiet.
For the twelve-week averaging test under SW 14.3B(b)(ii), total pay across the window is: 8 busy weeks (8 × 43 × £12.82 = £4,410.08) plus 4 quiet weeks (4 × 28 × £12.82 = £1,435.84), totalling £5,845.92. The required threshold is 12/52 of £25,000 = £5,769.23. The total of £5,845.92 exceeds this by £76.69, the averaging test is passed. The busier weeks generate enough additional pay to absorb the four quieter weeks within the twelve-week window.
However, the margin is slim. If even one of those busy weeks had dropped to 35 hours instead of 43, the twelve-week total would have fallen to £5,743.36, below the threshold and a compliance failure. Sponsors in the care sector should monitor rolling twelve-week totals closely, particularly where hours fluctuate regularly.
- Seventeen-Week Averaging for Variable Working Patterns
A distinct provision under SW 14.3B (c) addresses circumstances where the worker’s contracted hours are not uniform from week to week, such as sectors where rotas change regularly or seasonal variation affects working hours. In these cases, the applicable compliance period extends to seventeen weeks, and the total salary paid across that period must equal at least 17/52 of the annual minimum salary threshold. Sponsors intending to rely on this provision must confirm the irregular working pattern on the Certificate of Sponsorship.
Example (non-compliant): A private healthcare provider sponsors a registered nurse (SOC 2237) at the Band 5 going rate of £29,970 per year (£15.37 per hour based on 37.5 hours per week). The nurse works a variable shift pattern, covering different wards, rotating between day and night shifts, and working longer hours in some weeks when covering for colleagues, with lighter weeks when the rota allows. The sponsor confirms this irregular working pattern on the CoS and relies on the seventeen-week provision under SW 14.3B(c).
Over a seventeen-week window, the nurse works the following pattern: six weeks at 42 hours covering staff shortages on busy wards (6 × 42 × £15.37 = £3,873.24), five weeks at 37.5 hours on the standard rota (5 × 37.5 × £15.37 = £2,881.88), four weeks at 30 hours during a lighter rota period caused by ward restructuring (4 × 30 × £15.37 = £1,844.40), and two weeks at 20 hours during a temporary ward closure for refurbishment (2 × 20 × £15.37 = £614.80). Total pay across the seventeen-week window is £9,214.32.
The per-period going rate test under SW 14.3B(a) is met in every individual week, the nurse is paid £15.37 for every hour worked. However, the threshold under SW 14.3B(c) is 17/52 of the required annual salary of £29,970, which is £9,797.88. The total of £9,214.32 falls £583.56 short, a compliance failure, despite the going rate being met in every single week the nurse worked.
The shortfall arises because the lighter weeks drag the average hours across the window down to approximately 35.3 per week, below the 37.5-hour baseline on which the annual salary and the 17/52 threshold are calculated. The busier weeks covering staff shortages do not generate enough additional pay to compensate. Because the salary is set at the going rate with no headroom, there is no margin to absorb periods of reduced hours within the averaging window.
- Permitted Salary Subtractions
SW 14.3B (d) also addresses situations where salary falls below the required level during a defined pay period due to salary deductions that are permitted under the existing provisions of SW 14.2(a). Where this occurs, sponsors must be able to demonstrate that any shortfall is attributable to those permitted deductions, not to underpayment, and that the worker’s gross earnings over the course of their sponsorship will still meet the annual salary requirement.
Understanding Your Compliance Risk
The practical compliance risk under SW 14.3B is not uniform across all sponsored roles. Where a worker’s salary is set significantly above the occupation going rate, the sponsor has built-in headroom: a payroll error, a period of extended hours, or a run of lighter weeks is less likely to push any individual pay period or averaging window below the threshold. Where the salary is set at or close to the going rate, which is the position for the majority of sponsored workers, particularly in care, healthcare, and other sectors where sponsors typically offer the minimum compliant salary, there is little or no margin.
Every pay period matters, and even a minor payroll discrepancy or a short run of reduced hours can trigger a compliance failure that cannot be corrected retrospectively. Sponsors should assess where each of their sponsored workers sits relative to the applicable going rate and prioritise compliance monitoring for those with the narrowest margins.
How This Differs from the Previous Approach
The previous compliance approach treated annual salary as the primary reference point. A worker’s payslips might reflect uneven monthly payments, but provided the contracted annual salary met the going rate and minimum threshold for their occupation, such variation did not typically create a compliance risk under the Immigration Rules.
The introduction of SW 14.3B has closed that gap. Salary compliance is now explicitly tied to payroll cycles, and UKVI officers reviewing sponsor records can compare individual payslips and payroll data against the pay period thresholds contained in the Rules. An arrangement that appeared compliant on an annual basis may now give rise to compliance concerns if salary during any relevant period falls below the applicable threshold.
This represents a structural shift in how the Home Office scrutinises sponsored employment. The emphasis on payroll records means that sponsors can no longer rely primarily on the terms of a written contract; they must ensure that actual payments made during each payroll cycle consistently meet the required standards.
Transitional Arrangements and Key Dates
The amended rules took effect on 8 April 2026. The key dates are as follows:
- 5 March 2026: Statement of Changes HC 1691 published, inserting paragraph SW 14.3B into Appendix Skilled Worker.
- 7 April 2026: Final date on which the pre-amendment rules applied for applications covered by the transitional provisions (see below).
- 8 April 2026: New pay period compliance framework came into force for all applications not covered by the transitional provisions.
The transitional provisions in HC 1691 cover two distinct categories of application. First, applications made using a Certificate of Sponsorship issued before 8 April 2026 are decided under the Immigration Rules in force on 7 April 2026. Second, applications that do not require a Certificate of Sponsorship and were made before 8 April 2026 are also decided under the previous rules. Both categories are protected by the transitional provisions; all other applications are assessed under the updated pay period framework introduced by SW 14.3B.
For sponsors who issued a Certificate of Sponsorship before 8 April 2026 and whose application is still pending, the pre-amendment rules apply. For all new applications where the CoS was issued on or after 8 April 2026, SW 14.3B applies in full and each pay period must satisfy the applicable compliance threshold.
Practical Implications for Sponsor Licence Holders
The practical impact of these changes extends well beyond the moment of visa application. Compliance with the Skilled Worker route is an ongoing obligation, and the Home Office conducts both planned and unannounced audits of sponsor licence holders. With payroll records now forming a more central part of salary compliance, sponsors must ensure that their record-keeping practices are fit for purpose under the new framework.
Payslips, working hours data and payroll summaries need to be maintained in a form that clearly demonstrates salary compliance across the relevant pay periods. Sponsors should not assume that annual figures speak for themselves. Where payroll systems currently produce only annual or year-to-date summaries, teams may need to adjust reporting to break salary data down by individual pay period for each sponsored worker.
Organisations that operate compensation structures where salary is distributed unevenly across the year face the greatest adjustment burden. Whether through fluctuating monthly payments, deferred pay arrangements, or bonus-heavy models, any structure where the base salary during certain periods falls below the required going rate threshold for the hours worked is no longer protected by a compliant annual figure. The per-period test in SW 14.3B(a) operates independently of the annual salary position.
Sectors where weekly hours vary naturally, such as healthcare, hospitality, logistics and seasonal industries, need to ensure that variable-hours working patterns are formally documented and that the seventeen-week provision under SW 14.3B(c) is satisfied where it applies. The sponsor must confirm the irregular working pattern on the CoS itself.
The rules also require that pay cycles for sponsored workers correspond with the information recorded on the Certificate of Sponsorship and the employment contract. Any discrepancy between actual payroll arrangements and the documented terms may raise questions during a compliance visit. Given the risk of unannounced Home Office visits, sponsors should treat compliance as a continuous process rather than a point-in-time exercise. HR and payroll teams should understand what the new thresholds require and be able to produce supporting evidence promptly if requested.
Which Sectors and Employers Are Most Affected?
While the new rules apply across all Skilled Worker sponsorships, certain sectors are more directly affected than others.
Organisations in health and social care frequently operate variable-hours contracts. The seventeen-week averaging rule is particularly relevant here, and detailed records of working patterns are essential for demonstrating compliance.
Technology companies and financial services firms that use compensation structures involving lower base salaries supplemented by significant bonuses or performance-related pay need to assess whether the base salary alone meets the going rate thresholds during each compliance period, without relying on later top-up payments.
Hospitality, retail, and logistics employers, where flexible or shift-based contracts are common, should similarly review whether pay across relevant periods aligns with the required thresholds for each sponsored worker.
Steps Sponsors Should Take Now
The new pay period compliance framework is now in force. Sponsors who have not yet reviewed their arrangements should take the following steps without delay:
- Review sponsored employee payroll data: Identify any workers whose pay fluctuates across months or pay periods and assess whether their salary consistently meets the applicable compliance threshold under the new framework.
- Audit employment contracts and Certificates of Sponsorship: Check that the pay frequency and working pattern recorded in these documents accurately reflect the worker’s actual arrangements.
- Update internal record-keeping processes: Ensure that payroll systems can produce clear, period-by-period records of salary paid and hours worked for each sponsored employee.
- Brief relevant personnel: HR leads, payroll managers and compliance officers should be aware of the new requirements and understand which averaging rule applies to each worker category.
- Consider specialist advice: Where compensation structures are complex or compliance under the new framework is uncertain, taking advice from an immigration solicitor with experience in sponsor compliance is advisable.
What These Changes Mean for Your Organisation
The 2026 Skilled Worker pay period changes represent the most significant adjustment to salary compliance assessment within the Skilled Worker route in recent years. By enabling the Home Office to examine salary at the level of individual pay cycles, rather than relying primarily on annual figures, the new framework demands a more granular approach to payroll compliance from every sponsor.
The changes do not alter the fundamental salary thresholds that apply to the Skilled Worker route, nor do they prohibit variable pay arrangements outright. However, the new per-period thresholds mean that certain compensation structures, particularly those where base salary dips significantly in certain months, may fail compliance requirements in practice, even if the annual total appears sufficient. Variable pay itself is not banned, but sponsors must ensure that salary in every individual pay period meets the going rate for the hours worked, as well as satisfying the relevant three-month, twelve-week, or seventeen-week averaging test.
For organisations whose sponsored workers receive a consistent monthly salary that comfortably exceeds the applicable threshold, the practical impact may be limited. For those with more complex pay structures, immediate action is needed to ensure compliance with the framework now in force.
