Expanding from a single dental practice to multiple sites is a significant step that requires careful structural planning. The way you organise your dental group structure can impact everything from tax efficiency to operational flexibility and risk management.
Getting the structure right from the start saves considerable time and money later. Many dental groups that grow organically without proper planning find themselves with inefficient structures that are expensive to unwind.
Common Multi-Site Structure Options
Most successful dental groups use one of three main structures, each with distinct advantages and considerations.
Single Company Structure
The simplest approach involves one limited company owning and operating all practices. This structure works well for smaller groups with 2-4 sites where the practices are geographically close and operationally similar.
Advantages: Simple accounting and administration, lower compliance costs, straightforward profit extraction, and easier to manage initially.
Drawbacks: All practices share liability exposure, less flexibility for different profit-sharing arrangements, and potential complications if you want to sell individual sites later.
Subsidiary Structure
Here, each practice operates as a separate limited company, all owned by a parent holding company. This is often the most practical dental group structure for groups with 3+ sites.
Each subsidiary handles its own NHS contracts, employs its own staff, and maintains separate accounts. The holding company typically provides management services and owns the property or equipment.
Advantages: Risk isolation between sites, flexibility for different partnership structures, easier to sell individual practices, and cleaner due diligence for potential buyers or investors.
Partnership Structure
Some groups operate through partnerships, either traditional partnerships or Limited Liability Partnerships (LLPs). This approach is less common for multi-site operations but can work where the key principals want direct involvement in each location.
Holding Company Considerations
A holding company structure offers significant advantages for multi-site dental groups, particularly around tax efficiency and operational flexibility.
The holding company typically owns the shares in each practice subsidiary and may also own property, equipment, or provide central services like marketing, HR, and finance. This creates opportunities for group accounting efficiencies and centralised management.
For tax purposes, holding companies can benefit from substantial shareholding exemptions on dividends received from subsidiaries, making profit extraction more efficient across the group.
Consider whether the holding company should be owned directly by the principals or through separate personal holding companies. The latter provides additional flexibility for future restructuring and succession planning.
Tax and Accounting Implications
Multi-site structures create more complex group accounting requirements but also unlock tax planning opportunities not available to single practices.
Corporation Tax Planning
Each subsidiary company has its own corporation tax computations, which can be advantageous for managing profit levels and timing. Group relief allows losses in one company to be surrendered to profitable group companies, reducing the overall tax burden.
The small profits rate of corporation tax (19% on profits up to £50,000 in 2024/25) applies to each subsidiary company separately, potentially reducing tax compared to a single large company structure.
VAT Considerations
Each practice typically needs separate VAT registrations unless you opt for VAT group registration. VAT grouping can simplify administration by treating all group companies as a single VAT entity for most purposes.
However, VAT grouping also means all group companies become jointly liable for the VAT debts of any member. Consider this carefully, particularly if practices have different risk profiles.
Group Accounting Requirements
Dental groups exceeding certain size thresholds must prepare consolidated accounts. This applies if the group meets two of: turnover over £6.5m net, balance sheet total over £3.26m net, or more than 50 employees on average.
Even below these thresholds, consolidated accounts often provide better insight into overall group performance and are typically required by lenders or potential investors.
Operational Structure Decisions
Beyond the legal structure, consider how operational aspects will work across multiple sites.
Employment Structure
Decide whether associates and staff are employed by individual practice companies or by a central employment company. Central employment can simplify HR administration and provide flexibility for staff to work across sites, but may complicate things for practices with different ownership structures.
For associates considering the tax implications, the employment structure affects their self-assessment obligations and expense claims.
Property Ownership
Property can be owned by the trading companies, the holding company, or separate property companies. Property companies provide additional asset protection and can generate rental income that benefits from different tax treatment.
However, property companies also mean additional administration and potential SDLT complications on transfers.
Central Services
Consider which services to centralise. Common options include finance and accounting, marketing, IT support, compliance, and procurement. Centralised services can reduce costs and improve consistency, but need proper documentation for transfer pricing purposes.
Financing Multi-Site Expansion
The structure you choose affects how easily you can finance expansion and what funding options are available.
Lenders typically prefer holding company structures as they provide cleaner security arrangements and easier monitoring of overall group performance. When considering practice acquisitions, the existing structure can significantly impact the complexity and cost of the transaction.
Consider whether debt should sit at holding company level or with individual trading companies. Holding company debt can fund multiple acquisitions but may restrict flexibility for disposing of individual practices.
Risk Management
Multi-site structures should isolate risks while maintaining operational efficiency.
Professional indemnity insurance typically needs to cover all entities in the group. Consider whether to arrange this centrally or at individual practice level. Central arrangements can be more cost-effective but ensure coverage is adequate for all activities.
Separate practice companies limit cross-contamination of regulatory issues, employment disputes, and commercial problems. However, they don't eliminate all risks – personal guarantees often link principals to multiple entities.
Exit Planning Considerations
Your multi-site structure should support various exit strategies, whether selling individual practices, disposing of the entire group, or bringing in investors.
Clean subsidiary structures make it easier to sell individual practices without affecting the rest of the group. They also simplify due diligence and valuation processes.
Consider how different principals might exit at different times. Structures that work well for founder-owners may become problematic when some want to retire while others continue growing the group.
Getting Professional Support
Multi-site dental group structures involve complex interactions between tax, legal, and operational considerations. What works for one group may not suit another, depending on their specific circumstances and objectives.
The cost of getting the structure right initially is almost always less than the cost of restructuring later. Consider engaging specialists who understand both dental sector requirements and complex group structures.
Regular reviews are essential as groups grow and circumstances change. What worked at 3 sites may need adjustment at 10 sites, and tax rules and regulations evolve over time.
