Best sponsor compliance software under £100/month in 2026
Under £100 a month, which sponsor compliance software you can buy depends mostly on how many sponsored workers you have: at 5, 20 and 21 workers the cheapest option changes, as the table below shows (prices checked October 2026).
Soteriaa publishes this guide and is one of the tools compared.

The rule used in this guide
A product qualifies only where a currently published plan can be bought for £100 or less in advertised recurring software charges before VAT, or where an annual-only plan has a monthly equivalent of £100 or less, labelled as such. VAT is shown where the supplier states it. The comparison set is the ten sponsor-compliance products below, checked on 8 October 2026; it is a budget screen, not a feature ranking. Read the full sponsor compliance software comparison for the broader category map.

Monthly cost at 5, 20 and 21 sponsored workers
Advertised recurring software price per month for that headcount. “Ex VAT” means the supplier states VAT is extra; “VAT not stated” means its pricing page does not say. Annual figures are the published yearly price divided by 12.

What the table shows
The cheapest option changes with headcount.
Read across the three columns rather than looking for one winner.
At 5 workers
Soteriaa and UKVICAS both list £25/month (UKVICAS counts ‘users’). SponsorSafe works out at £40.83/month, but only if you pay £490 for the year.
At 20 workers
UKVICAS lists £75 for 20 ‘users’ and Soteriaa £79 for 20 sponsored workers. SponsorSafe Growth is £82.50/month if paid annually.
At 21 workers
No product in this set stays under £100 with a clearly defined capacity. SMS System Starter has the lowest published figure (£144.99 before VAT).
Who does not qualify — and why
Annaizu's monthly plans start at about £102 because of its 10-employee minimum; its annual rate brings that to £90/month, paid annually. ComplianceGuard's Basic plan is £150/month. Borderless asks buyers to request pricing, so it cannot be measured against the threshold. These omissions are evidence limits and price facts, not feature judgments.
If you already use general HR software
BrightHR and Breathe belong in a separate decision, not this specialist ranking.
They can cover parts of the underlying record keeping but should not be silently treated as identical sponsor products.
Read BrightHR alternatives for sponsor compliance or BreatheHR alternatives for sponsor compliance for that layering-versus-consolidation decision. Soteriaa itself is not a substitute for either product's broader HR functions.
- General HR systems can hold employee documents and expiry dates.
- The budget question is whether to keep that system and add a specialist sponsor layer when CoS, reportable changes, evidence completeness, deadlines and packs become the gap.
Soteriaa facts, disclosure and product boundary
Soteriaa publishes this guide and competes in the category. Its plans are £25/month for up to 5 sponsored workers, £79/month for up to 20 and £149/month with no worker limit, with every sponsor feature in each plan. You can import worker evidence (the fields are extracted for you to review, and nothing is added to the worker record until you confirm), and its AI assistant answers questions about your records; it is read-only and cannot change them. It gives no legal or immigration advice, makes no compliance determination, does not replace the Home Office Sponsor Management System, does not submit anything to the Home Office and does not perform right-to-work checks. Supplier prices are a snapshot checked on 8 October 2026; confirm VAT, promotions, annual terms and capacity definitions before purchase.
FAQ
Under-£100 sponsor software questions
The answers apply a consistent published-price rule to prices checked on 8 October 2026; always reconfirm commercial terms before you buy.
What sponsor compliance software costs less than £100 a month?
In the set compared here (checked 8 October 2026): Soteriaa through 20 sponsored workers (£25 or £79/month); SMS System Starter through 12 sponsored employees before VAT; UKVICAS's £25/£50/£75 tiers, which are counted in undefined ‘users’; LuwaSuite at £49/month for up to 5 employees (or up to 15 at £91/month if billed annually); Sponsoro through 15 workers (£49 or £99/month); SponsorFort Starter at £99 plus VAT for up to 5; and SponsorSafe Starter or Growth only as annual payments.
What is the cheapest sponsor compliance software for five workers?
At five, Soteriaa and UKVICAS both list £25/month, but UKVICAS counts ‘users’, which its pricing page does not define. Next come SponsorSafe at £490/year (about £40.83/month, paid annually), LuwaSuite at £49/month (£41 if billed annually), Sponsoro at £49/month, SMS System at £64.99/month before VAT and SponsorFort at £99/month plus VAT.
What can I use for 20 sponsored workers under £100/month?
Soteriaa Team is £79/month for up to 20 sponsored workers. SponsorSafe Growth is £990/year, about £82.50/month if paid annually. UKVICAS lists £75/month for 20 ‘users’. SMS System Starter is £139.99 before VAT at 20, and LuwaSuite and Sponsoro move to bands above £100.
What happens at 21 sponsored workers?
Nothing in this set stays under £100 with a clearly defined capacity. Soteriaa moves to £149/month (no worker limit). SMS System Starter is £144.99 before VAT, the lowest published figure at 21. SponsorSafe Professional is £1,990/year (about £165.83/month), LuwaSuite and Sponsoro are £219 (£183 billed annually) and £199/month, and UKVICAS publishes nothing above 20.
Is £99 plus VAT actually under a £100 budget?
It is under this guide's pre-VAT threshold, but it is £118.80 a month once 20% VAT is added. SponsorFort's £99 Starter is labelled accordingly and should not be treated as VAT-inclusive.
Can BrightHR or Breathe replace specialist sponsor software?
General HR platforms can support parts of sponsor record keeping. Whether that replaces a specialist layer depends on the sponsor-specific workflow your team needs, not on a generic ranking. See the BrightHR and Breathe sponsor-compliance pages linked below.
