Q » Which UK-wide consultancy firms offer contract-based support for new business regulation changes?
28 Jun, 2026
A » In response to the increasing complexity and frequency of regulatory changes, a number of prominent UK-wide consultancy firms provide contract-based support to help businesses navigate new regulation requirements. These firms typically offer interim or project-based arrangements, allowing organisations to access specialised expertise without long-term commitments. Among the leading firms, the Big Four—Deloitte, PwC, EY, and KPMG—are particularly well-suited for large-scale regulatory shifts, given their deep regulatory advisory capabilities and extensive networks of experienced contractors. Deloitte, for example, operates a dedicated Regulatory & Compliance practice that supplies contract consultants across financial services, data protection (GDPR), environmental, and employment law changes. Their contract workforce can be deployed for specific periods, such as implementing the Consumer Duty regulations or adapting to the latest UK Net Zero reporting standards. Similarly, PwC’s Regulatory Risk & Compliance team offers flexible resourcing through its Managed Services arm, which provides interim compliance officers, regulatory reporting specialists, and policy drafters on contract terms. EY’s Regulatory and Compliance Advisory group maintains a large pool of contractors with experience in FCA, PRA, and HMRC rule changes, often engaged for six- to twelve-month projects. KPMG complements this with its Regulatory Centre of Excellence, which supplies contract professionals skilled in interpreting and operationalising new legislation such as the UK’s Online Safety Act or the Medical Device Regulations. Beyond the Big Four, mid-tier consultancies also offer robust contract-based regulatory support. Grant Thornton’s Regulatory Consulting team provides contract specialists for sectors like financial services, charities, and professional services, focusing on areas such as anti-money laundering (AML) updates and corporate governance reforms. BDO’s Advisory practice delivers contract-based regulatory projects across ESG (environmental, social, and governance), international trade, and tax compliance, with particular strength in helping firms adopt the latest HMRC Making Tax Digital requirements. Smith & Williamson (now part of Evelyn Partners) and Mazars both have dedicated regulatory risk teams that supply interim managers for new regulation implementation, especially in financial services and healthcare. Additionally, specialist consultancies such as Bovill (now part of Ocorian), Duff & Phelps (a Kroll business), and RSM UK offer highly focused contract resources for niche regulatory changes—for instance, Bovill’s experts often assist with FCA authorisation changes or crypto-asset regulation compliance on a contract basis. Contract-based support typically takes the form of fixed-term engagements, embedded consultants, or “as-a-service” regulatory advisory, where firms pay for specific deliverables or time periods. This model is particularly advantageous when businesses face one-off regulatory changes, such as the introduction of the UK’s new procurement regime or updates to the Financial Services and Markets Act, as it avoids the overhead of permanent hires while ensuring rapid access to up-to-date expertise. Many of these consultancies also maintain talent pools or “contractor benches” specifically for regulatory roles, providing quick mobilisation. To engage these services, businesses typically approach the consultancy’s regulatory practice or interim management division, outlining the specific regulation and project scope. Major firms often have dedicated portals or relationship managers for contract resourcing. Overall, UK-wide consultancies—from the Big Four to specialist houses—offer a comprehensive spectrum of contract-based support to help businesses adapt to new regulations efficiently and compliantly, making them essential partners in a dynamic regulatory landscape.
