What makes a business idea viable for the Innovator Founder visa?

The test

Viability sits in two sub-paragraphs.

(b) the plan "must be realistic and achievable based on the applicant's available resources".

(c) the applicant "must have, or be actively developing, the necessary skills, knowledge, experience and market awareness to successfully run the business".

"Available resources" is the phrase that decides most viability questions. Viability is measured against what you have, not what you hope to raise. A plan that only works if a future round closes is contingent, not viable.

"Or be actively developing" is a deliberate concession. You need not arrive fully equipped. But active development means something you can point at: a course you are on, a mentor engaged, a co-founder who fills the gap, work already done. An intention to learn is not active development.

What the endorsing bodies are told to look for

The Home Office guidance to endorsing bodies sets four evaluation points under viability:

• sufficient funds to deliver the proposal
• credible financial projections
• appropriate applicant skills and experience
• evidence of genuine market demand

That last one is worth pausing on. Market demand appears under viability, not innovation. An assessor can accept that your idea is original and still refuse it because nobody has shown they will buy it.

UK Endorsing Services requires three-year financial forecasts comprising profit and loss, balance sheet and cashflow, alongside the business plan and the founder's CV. Its assessors review market research, competitor analysis, CVs, management structure and research and development activity. That tells you the level of financial detail expected, whichever body you use.

What assessors are actually looking for

Figures that reconcile. Funds available, costs in the plan, and the timeline should agree with each other. Most viability failures are arithmetic first.

Money that exists. Evidence that funds are available to the business. Where they come from a third party, evidence they are genuinely committed.

A credible first twelve months. Specific, sequenced, costed.

Honest unit economics. Cost to acquire a customer, value of that customer, and how you arrived at both. Assumptions are fine. Unstated assumptions are not.

A founder who fits the business, or a documented route to closing the gap.

Demand you can evidence, not demand you assert.

Risks identified. A plan with no risks reads as a plan not stress tested.

Common reasons this criterion fails

Projections detached from funding. Significant year two revenue built on money the founder does not have.

Growth with no driver. Revenue that rises because the chart says so.

Founder and business mismatch, unaddressed. No relevant background, no training, no hire, no acknowledgement.

Regulated activity with no route to authorisation. Financial services, healthcare, education, immigration advice and similar all need permissions. A plan that ignores the authorisation it needs is not achievable.

Costs obviously too low. Below-market salaries, no professional fees, no contingency. This reads as inexperience.

No evidence of demand. The gap the endorsing body guidance calls out expressly.

A single point of failure. One customer, one supplier, one channel, unacknowledged.

Worked illustrations

Generic illustrations. Not based on any real applicant or business.

Unlikely to meet (b): manufacturing funded by an unsigned term sheet. Equipment, premises and staff costed against investment discussed but not committed. On available resources, the plan cannot start.

Capable of meeting (b): a staged software build. Funds sufficient to reach a defined first milestone, with the plan explicit that stage two depends on revenue or further funding. Realistic because it does not pretend otherwise.

Unlikely to meet (c): a founder entering an unfamiliar regulated sector. No background, no qualification, no adviser, no acknowledgement that authorisation is needed.

Capable of meeting (c): a founder developing into the role. A technical founder without commercial experience, enrolled on a named programme, working with a named mentor, and joined by a commercially experienced co-founder. The gap is real and the response documented.

Unlikely to meet (b): a marketplace where both sides simply appear. Supply and demand arrive in month three because the plan requires it, with no acquisition cost attached to either.

Questions people ask

How much money do I need? There is no minimum investment requirement in the Rules for this route. What matters is that the plan is realistic on the resources you actually have. A modest plan properly funded beats an ambitious plan underfunded.

Can I rely on investment I expect to raise? Not for (b). Available resources means available. Future funding can feature in the growth story, but the plan must be achievable without it.

Do I need business experience? No. INNF 8.3(c) allows for skills you are actively developing. What it does not allow is an unaddressed gap.

What if my co-founder has the experience I lack? That can answer (c), provided the division of responsibility is clear and documented. Note that INNF 8.2(d) separately requires you to be the sole founder or an instrumental member of the founding team.

Can family provide the funds? Yes. The route does not restrict the source, but the funds must be genuinely available to the business, and under INNF 6.3 the endorsing body must be satisfied there are no concerns about their legitimacy and no reason to suspect illicit wealth.

Will a loss-making first year count against me? No. Most new businesses lose money in year one. What matters is that the losses are planned, funded and explained.
