About

An independent UK pensions and actuarial consultancy.

Founded in 2013. The firm exists to bring clarity to complex pension matters, and to give the people who have to act on the answer the confidence to decide. Congruent is the trading name for the Congruent group of companies; engagements are delivered through specific group companies — Congruent Actuarial Limited for regulated actuarial work, Congruent Risk Limited for the platform, Congruent Administrators Limited for SSAS administration. Senior-led from first conversation to final output.

The firm

Congruent provides senior-led actuarial work to sponsors and corporate finance teams, FCA-regulated firms, family-law and employment-law practitioners, trustees instructing alongside their existing Scheme Actuary, and the courts where the firm provides expert evidence. The firm’s work covers pension actuarial calculation across valuations, transfer redress, expert evidence in legal proceedings, integrated sponsor-side analysis, BPA fair-value pricing, and employment-related compensation — applied through the firm’s own Fair Value Framework methodology and operationalised through Congruent Calculations.

Congruent does not provide Scheme Actuary services to trustees and does not seek Scheme Actuary appointments. That structural position is foundational to the firm’s commercial register: the firm’s independence on every engagement is structural rather than declarative, and the work the firm produces is genuinely independent of any trustee-side incumbent relationship that might otherwise shape it. Engagements are senior-partner-led; institutional discipline runs through every output (TAS 100 compliance, the Congruent Quality Framework, FCA authorisation FRN 831289). Where the matter is Court-facing, the appropriate Expert at Congruent acts under APS X3 (The Actuary as an Expert in Legal Proceedings) and signs the report personally.

Independence and integrity are the firm’s working posture. Structural independence from the trustee-side advisory chain and from product providers ensures the firm’s analysis is genuinely independent of every commercial relationship that would otherwise shape it; integrity in the methodology means the answer is reproducible, the calculation is traceable, and the work withstands regulatory and judicial scrutiny.

The firm’s intellectual position

Two disciplines, woven into one methodology.

Market-consistent valuation discipline imported from modern finance, applied to traditional actuarial problems. Neither strand alone is the firm’s methodology — the Fair Value Framework is what holds the two together; Congruent Calculations is what operationalises the integration on every engagement.

The Leadership

Nasar Zamir

Director, Congruent Actuarial Limited

Founded Congruent in 2013 and leads the firm’s technical methodology and expert work. Author of Congruent Calculations and architect of the firm’s Fair Value Framework. Court-appointed Expert in pension on divorce matters. Twenty years’ experience in investment banking — fixed-income trading, structuring, sales and risk management; previously Head of Interest Rates sales at a large European bank.

Roger Grenville-Jones

Director, Congruent Actuarial Limited

Thirty years’ experience as a consulting actuary; previously Head of Actuarial Function in a global insurance company. Practice concentrated on expert-witness work in financial-product complaints and regulatory mis-selling programmes — pension opt-outs, transfers, FSAVCs, SERPS, mortgage endowments. Appointed by the FCA to provide expert evidentiary analysis in disciplinary proceedings; expert witness in an Ombudsman test case heard in the High Court.

What the firm offers

Three claims the firm’s architecture actually delivers.

Operational claims, not virtue claims. Each one is empirically testable against the firm’s structure and its outputs — not asserted, but built into how the firm works.

Independent

Structural independence from the trustee-side advisory chain (the firm provides no Scheme Actuary services and seeks no such appointments), from insurer relationships (no broking pipelines, no transaction-process incentives), and from financial product providers (no commercial ties that would distort advice). The firm’s commercial register is conflict-free by design; independence is a property of the firm’s structure, not a claim the firm asserts.

Senior-led

Partner-grade judgement on every engagement, from first conversation to final output. The firm’s two directors hold the regulatory and judicial accountability and lead the firm’s technical methodology and expert-witness practice. No outsourcing to junior staff at any stage. Where the matter reaches Court, the named Expert is the same person who performed the calculation, signed the report under the Statement of Truth, and attends for cross-examination.

Defensible

Every calculation captured as an audit-traceable CMC artefact — the calculation control ID, the method note, the assumption set, the data inputs, the result — reproducible by any competent actuary instructed to verify the work. Methodology compliant with TAS 100 (FRC), APS X2 / X3 (IFoA), and the procedural rules of the Court receiving the report (FPR Part 25, CPR Part 35). Not "rigorous"; not "high-quality"; defensible — the work withstands regulatory, judicial, and methodological scrutiny because the architecture exists to make that true.

Authorisations & credentials

The institutional architecture behind every engagement.

FCA-authorised, Bar-licensed, ICO-registered, quality-assured under the Congruent Quality Framework, professionally indemnified. Each authorisation is a structural constraint on how the firm operates — and a structural assurance for the firms and individuals who instruct.

Congruent Actuarial Limited is the firm's regulated operating entity, registered in England and Wales, authorised and regulated by the Financial Conduct Authority as a Claims Management Company. Professional Standards and Code of Conduct under the Institute and Faculty of Actuaries.

The firm holds a Bar Standards Board licence to instruct the Bar directly for advice and representation — relevant for litigation, expert-witness work, and contexts where direct counsel engagement is part of the instruction.

The firm's proprietary software, including the Congruent Calculations platform, is owned by Congruent Risk Limited. The full corporate structure across the Congruent group is set out at /business-information/.

The firm’s regulatory and professional standing is publicly verifiable. The FCA Register, the IFoA Find-an-Actuarial-Firm directory, and the Companies House public record all hold entries for Congruent Actuarial Limited — linked from the at-a-glance list opposite, and at /business-information/.
