AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
On a Skilled Worker visa, GOV.UK says you can work up to 20 hours a week for your own business, for example as a sole trader, while you keep doing your sponsored job. The business work must meet the same conditions as any extra job, and admin such as preparing invoices counts toward the 20 hours.
Hair, catering, tutoring, importing fabric, reselling foodstuff from home: plenty of Nigerians in the UK want a business alongside their job. On a sponsored work visa that is possible, but only inside the frame GOV.UK sets. This guide covers the Skilled Worker rules as they stand in October 2026.
What GOV.UK allows
GOV.UK's second job page says you can work up to 20 hours a week in another job or for your own business, provided you are still doing the job you are sponsored for. It mentions that there are various ways to set up a business, including registering as a sole trader.
The business work must meet one of the conditions that apply to all extra work:
- it has an eligible occupation code listed as 'higher skilled'
- it is on the Immigration Salary List
- it is in the same sector and at the same level as your main job
This is the part people miss. A software engineer freelancing in software, or a pharmacist doing locum work, may fit. A nurse running a catering business is in a different sector, and catering roles are unlikely to be listed as higher skilled, so that business may fall outside the rules even within 20 hours. Check the occupation code for what you will actually do.
What counts as working
GOV.UK says business administration, such as preparing invoices, counts toward your 20 hours. So do the other tasks of running a business: serving customers, making products, answering enquiries, sourcing stock. Keep a weekly log that includes them.
Things that are not running a business
- Holding savings or investments, such as an ISA, where you are not working.
- Owning a rented property in Nigeria managed by an agent, where your role is passive. Your own active management is a grey area; take advice.
- Selling personal possessions you no longer need.
These points are general observations, not rulings; if your situation sits near the line, a regulated immigration adviser can look at the detail.
Example
Example: Chioma is a sponsored data analyst. She wants to offer evening data-analysis work to small businesses. The work is in the same field and level as her job, so it may meet the 'same sector and same level' test. She plans 10 hours a week of client work and 4 hours of invoicing and admin, a total of 14, which is under the limit. Her friend Ebere, a sponsored accountant, wants to sell Nigerian snacks at weekend markets; that work is in a different sector and is unlikely to meet any of the three tests.
Steps before you start trading
- Describe exactly what work you will do in the business.
- Match it to an occupation code and check it against the three conditions.
- Estimate weekly hours, including admin, and keep them under 20.
- Check your employment contract for any limit on outside work.
- Set up separate records and a separate account for the business.
- Read HMRC's self-employment guidance and register when it says you must.
If a friend offers to put the business in their name so you can do the work, think hard. You would still be doing the work, and the arrangement creates risks for both of you, from tax to who owns the money. It is not a way around the visa conditions.
Tax and registration
A business brings its own tax obligations on top of PAYE from your job. HMRC sets out when you must register as self-employed and file a Self Assessment return; read its guidance before you start trading rather than after your first year. Keep business money separate from your salary account, so your records stand up if HMRC or the Home Office asks.
Other visas
The 20-hour rule above comes from the Skilled Worker pages. Student, dependant, Health and Care Worker and other visas have their own conditions on GOV.UK. Settlement changes your position again; see our ILR guide for what settlement costs. For extra employment rather than a business, read second jobs on a Skilled Worker visa.
Where Pryme fits
Pryme Personal and Business accounts can be opened from any country. A business with customers or suppliers in Nigeria can keep NGN, GBP, USD and EUR in a Business Account, raise invoices, and keep business money apart from salary. A Business Account does not change what your visa allows; the 20-hour limit and the conditions still apply.
Questions people ask
Can I be self-employed on a Skilled Worker visa?
GOV.UK says you can work up to 20 hours a week for your own business, such as a sole trader business, while doing your sponsored job, if the work meets the conditions for extra work.
Does admin count towards the 20 hours?
Yes. GOV.UK says business administration such as preparing invoices counts toward your 20 hours.
Can I sell food or hair products on a work visa?
Only if that work meets one of the conditions: higher skilled, on the Immigration Salary List, or same sector and level as your sponsored job. Most retail or catering work will not.
Can I run a business in Nigeria while on a UK work visa?
Working for your own business counts whether customers are in the UK or Nigeria. Passive ownership is different from working. Take advice if you are unsure where your activity falls.
