Lambert Chapman

What Lambert Chapman does

Lambert Chapman LLP is a UK chartered accountancy and business advisory firm established in July 1970, headquartered in Braintree, Essex, with additional offices in Maldon and Shoreditch, London. The firm operates as a partner-led Limited Liability Partnership with 7 partners and over 50 support staff, and is a member of the UK200Group. It serves a distributed client base spanning sole traders, partnerships, limited companies, LLPs, high-net-worth individuals, landlords, contractors, charities, and owner-managed businesses across Essex, Greater London, and the wider East of England, with specialist services including charity audits, IR35 advisory, corporate finance, and a dedicated Forensic Accounting & Litigation Support sub-brand.

The firm's core technology stack is built on third-party cloud accounting platforms — Xero, QuickBooks (with Elite ProAdvisor accreditation), and Sage — supplemented by HMRC-approved payroll software, a Virtual Cabinet Portal for secure document exchange and e-signature, and WorldPay for online invoice payments. There is no proprietary platform or AI/ML capability disclosed; delivery is partner-led with the same accounting team typically maintaining multi-decade relationships with clients. Service lines span business accountancy (annual accounts, audit, business tax), business support (payroll outsourcing for 350+ clients processing 3,000+ monthly payslips, management accounts, bookkeeping, company secretarial, start-up advisory), and personal accountancy (Self Assessment, inheritance tax and estate planning, personal tax planning).

The revenue model is professional services: fixed-fee quotes for compliance work (annual accounts, Self Assessment, audit), a fixed transaction-based tariff for monthly payroll bureau services, and project-based pricing for advisory engagements (corporate finance, forensic accounting, IR35). A subscription-style Tax Investigation Service provides recurring fee-protection cover. Go-to-market is overwhelmingly referral-led from existing long-tenured clients, supplemented by invitation-only networking breakfasts across Mid and North Essex and Suffolk, content marketing (blog, publications, email newsletter), community sponsorship (local sports clubs, Charity of the Year partnerships including Dementia UK 2025–2026), and active social media presence on LinkedIn, Facebook, Twitter, and YouTube.
