Pre-engagement, in-flight and post-engagement support.
For firms responding to FCA, PRA, or TPR enquiries — methodology defence, response drafting, sample reproducibility exercises, and engagement with the regulator's technical team. The firm's authorisations and CMC™ convention support credible engagement on substantive technical matters.
The regulators
Three phases of engagement
Where the firm fits
Regulatory engagement work splits broadly into two complementary roles: technical (the methodology, the sample, the calculation, the apparatus) and strategic (the relationship, the negotiation, the political dynamics, the timing). The firm operates in the technical role. Where strategic regulatory advice is required — relationship management with the regulator's senior team, cross-sector positioning, escalation-routing — that work sits with regulatory law firms and dedicated regulatory-strategy consultancies. The firm's role is to make sure the technical apparatus underpinning the engagement is defensible.
This division matches the regulator's own organisational structure: technical specialists on the one side, supervision-relationship managers on the other. Substantive technical engagement with the technical specialists is what the firm contributes; the supervision relationship belongs to the firm's regulatory legal advisers and senior management.
The CMC™ convention as engagement material
The firm's Check My Calculation™ artefacts — produced for every productised engagement and for many advisory engagements — are engagement-grade material for regulatory dialogue. A CMC™ ties an output figure to a calculation control ID, the configuration in use, the data schema applied, and the audit log of every calculation step. Where a regulator asks the question "show us how you got from inputs to outputs", the CMC™ is the answer.
For firms preparing for FCA enquiry, PRA examination, or TPR scheme-funding review, the firm can supply CMC™-grade documentation of methodology in advance — the apparatus the regulator's technical team will engage with when the enquiry arrives.

Scoped through a first conversation with the firm.
Fixed-fee engagement
For well-defined regulatory submissions: technical responses to specific FCA or TPR queries, position papers on methodological matters, or reviews of disclosed methodology. Fee agreed at scoping.
Time-and-materials
For matters where the regulator's position is still developing or the firm's role evolves: ongoing supervisory engagement, multi-phase technical work, or thematic-review involvement. Rate agreed at scoping; senior-led throughout.
Statement of Work — how the fee is fixed
Engagements are scoped through a first conversation and then fixed in writing before any work begins. The firm’s Invitation Letter contains a Statement of Work fixing: the scope of the engagement, the timetable for delivery (key milestones and final-deliverable date), the price (with any stage payments scheduled against milestones), and the named individuals on both sides.
The scope-to-price conversion is based on the firm’s published charge-out rate: £350 per hour for engagements led by a Director or Senior Actuary (the only grades that lead engagements at Congruent). The Statement of Work converts scoped hours into a fixed fee — the buyer’s commercial commitment is to the fee in the Statement of Work, not to an open-ended hourly meter.
The firm tends to come in competitively on the fixed quote. Because Directors lead engagements directly — without the layered team structure typical of larger firms — scoped hours convert into a fixed fee that compares favourably against equivalent senior-led work elsewhere in the market.

The methodological position behind the engagement.

If the regulator has signalled a substantive technical concern, the first conversation is technical.
Pre-engagement support is most valuable; in-flight engagement is most common; post-engagement remediation is what the firm's productised Solutions deliver. The firm responds within one working day with whether it can engage and what conflicts (if any) apply.
