What Rayner Essex does

Rayner Essex is a UK chartered accountancy firm founded in 1967, operating as Rayner Essex LLP from offices in London and St Albans. It delivers a full-service professional offering across audit and assurance, accounting and bookkeeping, VAT, payroll (including auto-enrolment and BACs Bureau processing), corporate and private client tax, corporate finance, company secretarial, charities, and international tax. Its technology stack is built on certified third-party cloud accounting platforms — QuickBooks (Elite ProAdvisor), Xero (Gold Partner), Sage, FreeAgent, Dext, and AutoEntry — selected per client rather than via a proprietary platform, with explicit support for Making Tax Digital compliance.

The firm serves SMEs, owner-managed businesses, private individuals and families, start-ups, large corporates, multinationals, and charities. It is the London member of INPACT International, a worldwide alliance of 160+ independent accountancy firms across 70+ countries, which provides cross-border tax, audit, and corporate finance capability through referrals and coordinated engagement. Rayner Essex is partner-led and relationship-driven, with each client assigned a fixed senior point of contact and services quoted on a bespoke per-engagement basis. The seven named partners (Simon Essex, Antony Federer, Lucy Ghawss, Neil Heyes, Laith Hilfi, Darren Hill, Mark Moore) and supporting directors and managers cover core disciplines.

Revenue derives from ongoing client retainers, project-based engagements, and compliance work across the listed service lines. The firm has no parent company, no external institutional capital, and no subsidiaries; it is independently owned by its partners. Distribution is direct through the two offices plus website enquiry channels, with international reach delivered via INPACT. Headcount sits in the 101-250 band and the firm has invested in sustainability commitments (100% renewable energy at St Albans, Ecologi partnership, first Impact Report published 2025) without disclosing financials or operating margin data.
