Most dental practice principals ask the same first question: how long will it take? The honest answer is longer than you probably expect — and the timelines are driven by regulatory processes you cannot compress. Understanding each stage before you start means you can plan properly, avoid the delays that commonly derail transactions, and set a realistic target completion date from the outset.
Two headline figures to anchor your planning:
- Decision to completion: 12–18 months is typical for a well-prepared NHS practice.
- Instruction to completion: 9–12 months once you formally go to market.
Private practice is faster — no NHS novation removes one condition precedent, and the process from instruction to completion is typically 6–9 months. For a mixed practice the NHS element sets the pace.
Timeline Overview: Stage by Stage
| Stage | Typical Duration | Notes |
|---|---|---|
| 1. Preparation | 4–12 months | Minimum 4 months for a clean practice; up to 12 months if accounts, CQC, or associate agreements need work |
| 2. Marketing to credible offer | 4–8 weeks | From formal instruction to best offer; well-prepared practices move faster |
| 3. Heads of Terms | 1–3 weeks | Long-stop date must allow for NHS novation + CQC timelines |
| 4. Due Diligence (NHS practice) | 8–12 weeks | Data room quality is the primary lever — gaps add weeks |
| 5. Legal / SPA (overlapping DD) | 6–10 weeks | Runs in parallel with due diligence |
| 6. NHS Novation (from exchange) | 4–8 weeks | Condition precedent; ICB area affects timing |
| 7. CQC Registration (critical path) | 12–24 weeks | Buyer must apply during DD — not after exchange. This is the transaction’s critical path. |
Stage 1: Preparation (4–12 Months)
The preparation phase is the most underestimated part of the process. It starts the clock on your overall timeline, and what you do (or don’t do) here determines how smooth or difficult every subsequent stage will be.
A well-prepared practice can be ready to instruct a broker within 4 months. A practice with outstanding issues — accounts that need filing, CQC compliance gaps, associate agreements that are unsigned or expired, or a principal who is still doing the majority of clinical revenue — can take 9–12 months to get into marketable condition.
The preparation checklist:
- Accounts: Three years of clean, filed statutory accounts with a normalised EBITDA schedule prepared by your accountant. If accounts are overdue or contain errors, fix them before marketing — buyers and lenders will not proceed without them.
- CQC: Registration current, Nominated Individual confirmed, most recent inspection report available. Any outstanding compliance issues addressed.
- Reduce principal dependence: If the principal delivers the majority of clinical income, buyers will apply a risk discount. A transition plan to associate-led delivery — even partially — increases value and buyer confidence.
- Tax advice: Brief a specialist dental practice accountant on deal structure, Business Asset Disposal Relief eligibility, and whether a share or asset sale is preferable for your circumstances. Getting this wrong is expensive and difficult to undo mid-transaction.
- Associate agreements: All associates should have signed, current agreements. Notice periods, UDA targets, and restrictive covenants will be scrutinised in due diligence. Issues here are one of the most common causes of mid-transaction price renegotiation.

Stage 2: Marketing to Credible Offer (4–8 Weeks)
Once you formally instruct a broker, the confidential marketing phase begins. The broker prepares an information memorandum, approaches qualified buyers under NDA, conducts site visits, and manages the offer process.
The timeline from instruction to a credible written offer is typically 4–8 weeks for a well-prepared practice. This is not a stage where preparation shortcuts can be taken — buyers who cannot get the information they need simply move on to other opportunities. A complete, well-organised data room ready at instruction means the process moves in weeks, not months.
What happens during marketing:
- Broker prepares anonymised teaser and full information memorandum (IM)
- Qualified buyers approached from broker database (DSOs, PE-backed groups, independent buyers)
- Buyers sign NDA, receive IM, conduct site visits
- Formal offers submitted in writing
- Broker manages competitive tension; seller selects preferred buyer
Stage 3: Heads of Terms (1–3 Weeks)
After selecting a preferred buyer, the parties agree heads of terms (HoT) — a non-binding summary of the key deal terms: price, structure (asset or share sale), any deferred consideration, transition period, and conditions precedent.
HoT are typically agreed within 1–3 weeks of offer selection. The most important and commonly overlooked clause is the long-stop date — the backstop date by which completion must occur for either party to walk away.
Why the long-stop date matters: For an NHS practice, the long-stop must account for both NHS novation (4–8 weeks from exchange) and CQC registration (12–24 weeks from the buyer’s application). If the long-stop is set at, say, 6 months from HoT signature, it may be too tight for CQC to complete — particularly if the buyer has not yet applied. A realistic long-stop for an NHS practice sale is 9–12 months from HoT, or explicitly conditional on CQC registration.
Stage 4: Due Diligence — 8–12 Weeks for an NHS Practice
After HoT are signed, the buyer’s advisers conduct formal due diligence. For an NHS dental practice, this typically runs 8–12 weeks. The data room is the primary lever: a complete, well-organised data room with all documents ready from day one compresses this stage significantly. An incomplete data room can add 4–8 weeks of back-and-forth queries.
What buyers check:
- Three years of statutory accounts, management accounts, and normalised EBITDA
- NHS contract documentation and three-year UDA delivery record
- Associate agreements — notice periods, restrictive covenants, UDA targets
- Lease — remaining term, assignment provisions, landlord consent requirements
- CQC registration and inspection history
- Employment contracts, staff schedule, pension arrangements
- Equipment register and service records
- Any NHS performance notices, litigation, or regulatory correspondence
Common causes of DD overrun:
- Missing or disorganised documents requiring multiple rounds of queries
- Contested addbacks on the normalised EBITDA (if the seller’s accountant and buyer’s accountant cannot agree, it goes back to negotiation)
- Associate employment status issues — associates operating without proper self-employed contractor agreements, or with employment characteristics, create IR35 and TUPE risk that needs resolution
- Lease issues — short term, non-assignable clauses, or uncooperative landlord
Stage 5: Legal / SPA — 6–10 Weeks (Overlapping DD)
The sale and purchase agreement (SPA) and ancillary legal documents (disclosure letter, tax deed, transitional services agreement) are drafted and negotiated in parallel with due diligence. This phase typically runs 6–10 weeks, though the clock only starts once both parties have instructed specialist solicitors and the first draft SPA has been issued.
Using a solicitor with dental practice M&A experience materially reduces legal phase duration. Solicitors unfamiliar with NHS novation mechanics, CQC registration, or dental-specific warranty carve-outs take longer and create more correspondence.
Causes of SPA delay:
- SPA warranty disputes — disagreements about the scope of seller warranties, particularly around NHS contract delivery, associate status, and CQC compliance
- Disclosure negotiations — seller and buyer’s solicitors negotiating which matters qualify as disclosure against warranties
- Buyer’s lender requiring changes to the SPA (common with bank-financed purchases)
Stage 6: NHS Novation — 4–8 Weeks from Exchange
NHS contract novation is the formal transfer of the NHS contract from the selling contractor to the buying contractor. It requires the ICB (Integrated Care Board) to approve the buyer as the incoming contractor. Novation is a condition precedent — completion cannot happen until the ICB has issued the novation agreement.
The application is typically submitted at or around exchange of contracts, and the ICB issues the novation agreement within 4–8 weeks. ICB area matters: some ICBs process novation applications promptly; others have significant backlogs.
What affects NHS novation timing:
- ICB area variation — processing times differ materially across ICBs
- Whether the buyer is already a registered GDS contractor (new registrations add time)
- Outstanding NHS performance notices on the practice
- Incomplete application documentation
The solicitor managing novation should file the application proactively and chase the ICB regularly. A passive approach adds weeks.
Stage 7: CQC Registration — 12–24 Weeks (The Critical Path)
CQC registration is the single most important timeline factor in a dental practice sale. Many sellers — and some advisers — do not appreciate how long it takes until it is already causing a problem.
The buyer must apply to CQC to register as a new provider at the practice location. CQC conducts a Fit and Proper Person assessment, reviews the location application, and issues the new registration certificate. This process takes 12–24 weeks.
The critical operational implication is this: the buyer must submit their CQC application during due diligence — not after exchange of contracts. If the buyer waits until after exchange to apply, the CQC registration will not be ready at completion, and the long-stop date will be breached. In practice, exchange is typically conditional on CQC registration, which means CQC is on the critical path from the moment HoT are signed.
What affects CQC registration timing:
- CQC processing capacity — 12 weeks is achievable in periods of normal workload; 24 weeks or longer occurs when CQC has backlogs
- Completeness of the buyer’s application — incomplete applications are returned and restart the clock
- Fit and Proper Person issues — any adverse history, disqualification, or fitness concern on the buyer extends the timeline
- Outstanding concerns on the existing registration — if the practice has unresolved CQC enforcement action, the new registration is delayed
For sellers, the practical advice is to raise CQC application timing explicitly with the buyer at the HoT stage and confirm the application has been submitted before exchange. The experienced brokers and solicitors will manage this proactively; those unfamiliar with dental transactions often do not.
NHS vs Private: How the Timeline Differs
Private dental practices complete significantly faster because NHS novation and CQC-gated completion are not required:
| NHS Practice | Private Practice | |
|---|---|---|
| Decision to completion | 12–18 months typical | 8–14 months typical |
| Instruction to completion | 9–12 months typical | 6–9 months typical |
| Critical path | CQC registration (12–24 weeks) | Legal / SPA (6–10 weeks) |
| NHS novation required | Yes — condition precedent | No |
What Accelerates the Process
- CQC application submitted early. The single biggest controllable accelerator. Confirm the buyer has applied during DD, not after exchange.
- Organised data room ready at instruction. A complete, structured data room means due diligence proceeds without delays for missing documents.
- Clean accounts and an agreed normalised EBITDA. Avoids contested addback negotiations that stall financial DD and price agreement.
- Experienced specialist solicitor managing NHS novation proactively. Filing the application early, chasing the ICB regularly, and anticipating what the novation agreement will require removes weeks from this stage.
- Preparation completed before marketing. Sellers who go to market with associate agreements resolved, leases reviewed, and CQC documentation in order move significantly faster through DD.
What Delays the Process
- Incomplete data room. The single most common cause of delay across all stages. Every missing document generates a query; every query adds days. Queries on core documents — accounts, NHS contract, associate agreements — can add 4–8 weeks.
- Slow ICB area. NHS novation timelines vary significantly by ICB. Some process applications in 4 weeks; others routinely take 8–12 weeks. This is outside the seller’s direct control, but an experienced solicitor with knowledge of the relevant ICB will calibrate expectations and chase proactively.
- CQC delays. If the buyer submits their application late, or if CQC has a processing backlog, completion is held up. A 24-week CQC timeline on a sale with a 9-month long-stop creates serious risk.
- Contested addbacks. If the seller’s accountant and buyer’s accountant disagree on normalisation adjustments, price renegotiation can follow. This is most commonly triggered by items that look personal but are argued to be business-necessary, or by adjustments the buyer deems non-recurring that the seller claims are structural.
- SPA warranty disputes. Disagreements about the scope of NHS contract warranties, CQC compliance representations, and associate status warranties are common. A seller without specialist dental M&A legal advice often gives broader warranties than necessary; a buyer pushing hard on warranty scope can stall negotiations for weeks.
- Associate employment status issues. If associates are found during DD to have employment characteristics — fixed hours, no substitution right, integrated into practice management — the buyer faces IR35 and TUPE exposure. This is a common issue in older practices with longstanding associates and can require restructuring or price adjustment before the transaction can proceed.

Frequently Asked Questions
How long does it take to sell a dental practice?
From decision to completion, a well-prepared NHS dental practice sale typically takes 12–18 months. From formal instruction (going to market) to completion, it is typically 9–12 months. Private practices are faster — 6–9 months from instruction to completion — because there is no NHS novation. The critical path in any NHS practice sale is CQC registration, which takes 12–24 weeks and must be initiated by the buyer during due diligence, not after exchange.
Why does CQC registration take so long?
CQC is required to conduct a Fit and Proper Person assessment on the buying provider and register them at the specific practice location. The process is conducted by CQC’s provider registration team and takes 12–24 weeks depending on workload and the completeness of the application. There is no fast-track option. This means the buyer must submit their application as early as possible — typically during due diligence — for the registration to be ready in time for completion.
What is the minimum realistic time to sell a dental practice?
For a private practice with a well-prepared seller and an experienced buyer, completion in 5–6 months from instruction is achievable. For an NHS practice, the absolute minimum is around 7–8 months — and only if CQC registration is applied for immediately after HoT and processes quickly. Most NHS practice sales take 9–12 months from instruction. Setting an expectation below 9 months for an NHS practice creates long-stop date risk.
What is NHS novation and why does it affect the timeline?
NHS novation is the formal process by which the ICB transfers the NHS contract from the selling dentist to the buying dentist. It requires ICB approval and typically takes 4–8 weeks from the date of application. Novation is a condition precedent in dental practice sale agreements — completion cannot occur until the ICB has issued the novation agreement and the transfer date is agreed. Completion is typically timed to coincide with the NHS novation date, which means the novation date effectively sets the completion date.
