London (North London News) September 9, 2026 — Following a major regional expansion push across the South East, mid-tier accountancy consolidation firm bk plus has officially finalized the strategic acquisition of North London practice Joshua Leigh & Co.

Why is bk plus expanding into North London with its acquisition of Joshua Leigh & Co?

In a major regional move, fast-growing accountancy practice bk plus has extended its presence across the South East through the takeover of Joshua Leigh & Co, an established chartered accountancy firm based in Barnet, North London.

As reported by Accountancy Today editor Steven Morgan, bk plus has been pursuing an aggressive deal-making campaign to establish regional hubs across England, Scotland, and Wales. The buyout of the Barnet practice provides bk plus with a dedicated foothold in North London, unlocking direct access to the suburban commercial corridor and owner-managed business communities.

Founded and led by Joshua Finn, Joshua Leigh & Co provides a wide spectrum of specialized accountancy services. The firm caters extensively to owner-managed enterprises, limited companies, general partnerships, and private high-net-worth individuals operating in North London and the surrounding home counties. The core service offering provided by the Barnet office encompasses:

• Statutory audit and independent financial assurance
• Year-end accounts preparation and statutory compliance
• Personal income tax, capital gains, and self-assessment filing
• Value Added Tax (VAT) planning, compliance, and reporting
• Day-to-day bookkeeping and real-time financial tracking
• Full-service payroll management and corporate secretarial support

Under the terms of the agreement, the leadership confirmed that Joshua Finn and his existing staff will remain based at the firm’s Barnet premises. Clients will maintain their established points of contact to ensure continuity of service, while gaining access to bk plus’ wider pool of national corporate finance, forensic accounting, and specialized tax advisory capabilities.

How will the acquisition impact clients and the leadership of Joshua Leigh & Co?

Commenting on the consolidation, Managing Director Joshua Finn stated that joining forces with the larger entity represents an advantageous shift for both the firm’s workforce and its established client portfolio.

As detailed in official corporate filings by bk plus, Finn emphasized that the primary focus remains centered on client continuity. Statements released regarding the transition confirmed that client accounts will continue to be serviced under the same operational framework, preserving the long-standing partner-led approach that built the firm’s reputation.

Writing for Accountancy Today, financial reporter Steven Morgan highlighted statements from Joshua Finn, who remarked:

“Joining bk plus represents a positive step for both our clients and our team. Clients will continue to receive the same high standard of personal, responsive service they have always had from us. We have always focused on building long-term relationships and delivering practical advice, and that will remain unchanged. Being part of a larger organisation gives us access to additional resources and specialist expertise that will benefit clients as their requirements become more complex. It allows us to broaden the support we can provide while maintaining the personal service that has been central to our business.”

What is bk plus’ long-term regional growth strategy?

The addition of Joshua Leigh & Co reflects a broader buy-and-build consolidation strategy deployed by bk plus to capture SME market share across the UK.

Addressing the deal, Shaun Knight, Chief Executive Officer of bk plus, emphasized the strategic geographic value of North London within the group’s overarching expansion mapping. As reported in recent regional business press coverage tracking UK professional service mergers, Knight pointed out that the acquisition aligns directly with bk plus’ core operating philosophy: combining hyper-local service delivery with national back-office scale.

In an official executive statement, Shaun Knight stated:

“Joshua Leigh & Co has built a respected practice in North London, supported by an experienced team and strong relationships with its clients. The firm’s commitment to delivering responsive, partner-led advice aligns closely with our approach. North London is an important market for bk plus and this acquisition further strengthens our presence in the region. We look forward to working alongside Joshua and his team as they continue to support clients and pursue future growth opportunities.”

Background of the particular development after the news

The acquisition of Joshua Leigh & Co comes amidst a historic wave of consolidation across the United Kingdom’s accountancy sector. Over recent years, private-equity-backed mid-tier accounting groups have aggressively acquired independent regional practices. Driven by increasing regulatory compliance burdens, rapid digital transformations (such as HMRC’s Making Tax Digital initiatives), and rising operational technology costs, small-to-medium practices (SMPs) are increasingly opting to merge with larger platforms.

Founded to service the small-and-medium enterprise (SME) market, bk plus has expanded at an unprecedented pace. Backed by institutional investment, the group has executed dozens of acquisitions across England, Scotland, and Wales. Throughout 2026 alone, bk plus secured landmark takeovers including Task Accounting in North Wales, Riches and Co in Surrey, and Aggarwal and Co in the South East.

This roll-up strategy has catapulted bk plus from a regional Midlands firm into a national professional services giant boasting more than 60 office locations and over 1,000 personnel. By acquiring established local practices like Joshua Leigh & Co, bk plus successfully bypasses the friction of organic client acquisition, instantly gaining established localized client books while deploying centralized IT, HR, and specialist legal/tax support infrastructure.

Prediction: How this development can affect small and medium-sized enterprises (SMEs)

This transaction signals a broader operational shift that will directly impact small and medium-sized enterprise (SME) owners, private businesses, and sole traders operating within North London and the home counties.

• Broader Access to Complex Advisory Services: Historically, independent practices like Joshua Leigh & Co excelled at personal, high-touch services (bookkeeping, routine tax filings, and annual accounts). However, growing SMEs often had to seek separate third-party advisers for complex corporate restructurings, cross-border tax advice, or research and development (R&D) tax credit claims. Under the bk plus umbrella, local SME clients in Barnet will now gain direct access to in-house corporate finance, deep tax planning, and specialized assurance teams without sacrificing their existing partner relationships.
• Fee Structure and Technology Modernization: As national groups integrate local offices, SMEs can expect accelerated adoption of advanced cloud accounting tools, automated data ingestion software, and AI-assisted financial analytics. While this technology upgrade promises more proactive, real-time insights for business owners, market trends suggest that firm consolidation across the UK accountancy landscape can gradually lead to standardized billing practices and fee adjustments as localized firms align with national group pricing models.
• Heightened Regional Competition: For competing independent accounting firms in North London, bk plus’ physical entrance into Barnet intensifies local market competition. Independent practices will face pressure to either modernize their tech stack and service models to retain clients, or consider entering into strategic merger discussions with larger national consolidation networks themselves.
