One of the most common reasons dental practice transactions stall — or fall through entirely — is poor document preparation. A buyer’s solicitors and accountants will conduct thorough due diligence. If you cannot produce clean, organised documents, buyers lose confidence, negotiations become protracted, and some buyers walk away.
The solution is straightforward: prepare your data room before you go to market. A well-organised data room makes you look like a serious, professional seller. It shortens due diligence from weeks to days. It removes buyer uncertainty that would otherwise be priced into the offer.
This checklist covers every document category a buyer will request, with notes on what to look for and how to prepare.
Financial Documents
3 Years of Statutory Accounts
The foundation of every valuation. Buyers and their finance providers (banks and specialist dental lenders) require three full years of statutory accounts from a recognised accountant.
What to check before going to market:
- Are all three years filed at Companies House (if applicable)?
- Are the accounts signed and dated?
- Do they clearly separate NHS and private income where relevant?
- Are director drawings/salary clearly shown?
Common problem: Accounts that are overdue for filing, or where the prior year’s accounts were submitted late. This raises questions about financial governance that buyers will probe.
Management Accounts
For practices with a financial year that ended more than 6 months ago, buyers will want recent management accounts to bridge the gap. These can be produced by your bookkeeper or accountant.
Format: Monthly profit and loss, year-to-date figures, and — where possible — a comparison against the prior year.
Tax Returns (3 Years)
Corporation tax returns for the practice entity, personal self-assessment returns for the principal if the principal draws income from the practice. HMRC must confirm no outstanding tax liabilities.
Bank Statements (12 Months)
Buyers review bank statements to verify that trading figures match accounts and to understand cash flow patterns. Some lenders require them as part of the finance application.
Aged Debtor and Creditor Lists
Current at the point of sale. Shows outstanding patient balances (for private plans) and supplier obligations.
NHS Contract Documents
For NHS and mixed practices, the NHS contract documents are often the most scrutinised part of the data room.
NHS Contract (GDS or PDS)
The original contract document, including the Schedule of Payments, UDA allocation, and any supplementary agreements. If you do not have the original, request a copy from NHS England or your Integrated Care Board.
UDA Delivery Schedule (3 Years)
Quarterly or annual UDA delivery reports for the last 3 years. This shows the practice’s track record against the contracted allocation. Under-delivery is the single biggest NHS-related red flag for buyers — it raises questions about future contract stability and ICB relationship quality.
What to do if there is under-delivery in your history: Be prepared to explain it (e.g., COVID impact, staff absence) with supporting evidence. Do not attempt to obscure it — it will be found.
ICB Correspondence (Last 3 Years)
Any written correspondence with NHS England or the Integrated Care Board relating to your contract — performance notices, clawback letters, contract variation letters, renewal correspondence. Buyers will ask for all of it.
Novation Information
The name and contact details of your NHS England local team or ICB commissioner. You will need this when the novation application is submitted post-heads of terms. For a full explanation of the novation process, see our guide on NHS contract novation when selling a dental practice.
CQC Registration and Compliance Documents
Current CQC Registration Certificate
The practice’s active registration certificate. Ensure it lists the correct registered manager and all regulated activities currently delivered.
Most Recent CQC Inspection Report
Buyers and their lenders review the CQC inspection report carefully. A “Good” or “Outstanding” rating is expected. A “Requires Improvement” rating will either narrow the buyer pool or result in a lower offer — buyers price in the remediation cost and risk.
If your last inspection was “Requires Improvement”: Address the specific improvement notices before going to market and request a re-inspection if possible. Do not attempt to sell with outstanding CQC concerns.
CQC Statement of Purpose
The current statement of purpose as registered with CQC.
Infection Prevention and Control (IPC) Records
Most recent IPC audit, lead IPC officer designation, and any HTM 01-05 compliance documentation. Buyers will check this.
Radiation Protection Documentation
Radiation Protection Supervisor (RPS) and Radiation Protection Adviser (RPA) records, equipment registration, and IRR17/IRMER compliance records.
Associate and Staff Documents
Associate contracts are one of the most common due diligence friction points. Verbal agreements and outdated contracts undermine buyer confidence.
Associate Agreements (All Current Associates)
Signed, written agreements for every associate currently working at the practice. These should specify:
- Session commitments
- NHS UDA allocation (if applicable)
- Private income split
- Notice periods
- Post-sale restrictive covenant terms (non-compete/non-solicitation)
Common problem: Associates on outdated NHS Performer agreements from the 2000s, or on verbal arrangements where the terms are not documented. Buyers will want updated, written agreements before exchange.
Employment Contracts (All Employed Staff)
All current employment contracts: dental nurses, reception staff, practice manager, hygienists, therapists, and any other employed roles. Ensure they are signed and in date.
Staff Handbook and Policies
Current employee handbook, including disciplinary procedures, grievance procedures, and any relevant policies (sickness, maternity/paternity, etc.).
Payroll Records (12 Months)
Recent payroll summaries showing current staff, hours, salaries, and pension contributions. Buyers and their legal teams will check TUPE compliance requirements.
TUPE Schedule
A current list of all employees with start date, role, salary, and contract type. This is the basis for the TUPE transfer schedule in the sale agreement.
Property and Lease Documents
Lease Agreement
If the practice is leasehold, the full current lease agreement. Buyers’ solicitors will review:
- Lease term remaining (ideally 10+ years including any renewal options)
- Assignment rights (can the lease be transferred to a buyer?)
- Landlord’s consent requirements for assignment
- Break clauses and rent review provisions
Common problem: Short lease terms (fewer than 10 years remaining, including renewal options) significantly narrow the buyer pool and may affect lender appetite.
Property Ownership Documents
For freehold practices, the title register from Land Registry and any associated title deeds.
Building and Equipment Service Records
Dental chair service records, compressor and suction maintenance records, and decontamination equipment service histories. Most buyers and their insurers want to see a clean recent service history.
Patient Membership Plan Documents
For practices with patient membership or capitation schemes:
Plan Provider Agreement
The contract with Denplan, Practice Plan, or other plan provider. Includes current fee rates and member count.
Current Membership Statistics
Number of active members, monthly income per member, and recent churn rate (members joining and leaving per month).
Patient Membership Financial Summary
Monthly plan income, ideally for the last 12–24 months.
Legal and Corporate Documents
Certificate of Incorporation
For limited company practices, the original Certificate of Incorporation.
Articles of Association
Current Articles of Association, including any amendments.
Shareholder Register and Confirmation Statement
Current shareholder register and most recent Confirmation Statement filed at Companies House.
Any Existing Loan Agreements
Details of any outstanding business loans, hire purchase agreements, or equipment finance arrangements. These will need to be disclosed to the buyer and may affect deal structure.
Presenting Your Data Room
The most common mistake sellers make is presenting documents in a disorganised way — emailing PDFs as they are requested, or providing different versions of the same document. This creates uncertainty and slows due diligence.
Best practice: Organise documents in a shared folder (Dropbox or Google Drive works well) with clear folders for each category above. Number the documents consistently. Provide an index.
A well-presented data room tells a buyer that you run an organised, professional practice. A disorganised one implies the opposite — and buyers price in what they cannot see.
What a Specialist Broker Does for Your Data Room
A specialist dental practice broker will review your data room before it is shared with buyers. This is one of the most practical things a good broker does — they know what buyers and their advisers will look for, and they identify problems before they become negotiating leverage.
If you are beginning to think about selling your practice, the earlier you start assembling this documentation, the better. A data room that is ready when you go to market means a shorter due diligence period, less disruption to the practice, and higher buyer confidence.

Frequently Asked Questions
What documents do I need to sell a dental practice?
The main categories are: three years of statutory accounts and tax returns, NHS contract documents and UDA delivery history, CQC registration certificate and inspection report, associate agreements for all current associates, employment contracts for all staff, lease documents (or property title), and patient membership plan documents where applicable.
How long does it take to prepare the data room for a dental practice sale?
For a well-organised practice, 4–8 weeks to compile and review everything. For practices with missing or incomplete documentation, 3–6 months is more realistic — particularly if associate agreements need to be updated or CQC issues need to be addressed before going to market.
What happens if I don’t have all the documents?
Missing documents do not necessarily stop a sale, but they do create negotiating leverage for the buyer. Missing associate agreements, incomplete NHS contract records, or outstanding CQC improvement notices will either reduce the offer price or result in conditional heads of terms that require remediation before exchange.
Do I need a solicitor to prepare the data room?
Your solicitor will be involved in the legal due diligence phase, but the data room is largely a business owner responsibility. Your accountant should prepare the financial schedules. Your specialist broker will tell you exactly what to prepare and review it before it is shared with buyers.
