Identify exactly what the FCA has issued
The response depends on the instrument. A section 165 FSMA information requirement is a formal demand for documents or answers. An early-engagement letter signals supervisory concern but no decision. A Pre-OIVOP letter warns that the FCA is minded to vary your permission. A formal Own-Initiative Variation of Permission notice under section 55J FSMA is a decision -- usually with a 28-day window to make representations to the Regulatory Decisions Committee.
FCA threshold conditions: the four limbs
The Schedule 6 FSMA tests the FCA applies to decide whether your firm should remain authorised -- legal status, location of offices, effective supervision, appropriate resources, suitability, and business model
Pinpoint the failing limb
FCA correspondence will name the threshold condition in issue. The most common triggers are appropriate resources (capital, liquidity, or non-financial resources), suitability (fit and proper concerns about senior managers or controllers), and business model (the firm's strategy is no longer viable or creates undue conduct risk). Map the FCA's concern to the specific limb before drafting any response -- a generic reply will not land.
Apply to vary your FCA permission
If the threshold-conditions concern can be resolved by surrendering or restricting a regulated activity, a voluntary variation of permission (VVOP) is faster and lower-risk than waiting for an OIVOP
Instruct specialist advisers
For any Pre-OIVOP or section 55J notice, instruct regulatory counsel and, if resources are in issue, a regulatory accountant. Decide early whether to (a) defend the threshold-conditions position with evidence, (b) offer a voluntary variation that addresses the concern, or (c) plan an orderly wind-down. Engaging credibly with the supervisor often de-escalates a Pre-OIVOP before any formal notice issues.
Understand the worst-case outcome
If the FCA concludes the threshold conditions are not, and will not, be satisfied, it can vary your permission to remove regulated activities or cancel Part 4A permission entirely under section 55J FSMA. A cancelled firm carrying on regulated activities afterwards commits the general prohibition offence under section 19. Understanding this end-point helps you weigh a voluntary variation against contesting the FCA's view.
Penalties for carrying on regulated business without authorisation
What happens if your permission is varied or cancelled and you continue to trade -- criminal offence under section 23 FSMA, unenforceable agreements under section 26, and FCA enforcement powers
