CBW claims to provide a “powerful combination of business and financial insights” that can relate to effective wealth management, business start-ups and scales, investment in assets and innovation, overseas expansion, tax efficiencies, regulatory compliance, and profitable growth.

As a full-service accountancy firm, CBW offers a range of service lines, including audit and accounts, tax, financial planning, corporate recovery and insolvency, corporate finance, research and development, forensic and investigation, outsourcing, and HR consultancy.

The group’s key specialist sectors are split into property, start-ups, regulated businesses, and logistics.

Recent Coverage

In May 2023, Carter Backer Winter was acquired by Gravita. At the same time, Gravita also acquired Davis Grant. The deals were facilitated by private equity investor Tenzing.

Gravita appointed four new partners, as the firm doubled down on its growth ambitions. The office move, completed in April, follows a period of deal making for the firm, which had also joined forces with Propel, Carter Backer Winter and Davis Grant.

Gravita resigned as Belluscura’s auditor due to an inability to meet its regulatory requirements in respect of its engagement with the company. As a result, Gerald Edelman LLP was appointed as the new auditor of Belluscura with immediate effect.

Gravita launched in 2022 with the intention of becoming the UK’s “leading” partner for SMEs. Clients will have access to a full-service firm with specialists all under one brand offering audit, tax, accounts, financial outsourcing, payroll and advisory.
