Key takeaways
CMA expands merger control beyond operators
Property ownership and influence can trigger competition scrutiny.
Local market concentration now drives risk
Even modest portfolios face CMA review at catchment level.
Care sector deals remain viable with preparation
Early competition analysis and structuring are now essential.
For anyone advising on transactions in the UK care home sector, the Competition and Markets Authority’s (CMA) investigation into Welltower Inc.’s recent acquisitions is the most significant development the market has seen in years. On 7 May 2026, the CMA concluded its Phase One review and found that each of the four completed acquisitions – of care homes managed by Barchester Healthcare, HC-One, Aria Care (including Asprey) and Danforth Care – may give rise to a substantial lessening of competition in local markets. Absent acceptable undertakings, all four deals are headed for an in-depth Phase Two investigation.
The combined transaction value is reported to be in excess of £6 billion and covers more than 600 operational care homes, plus a further pipeline of homes with planning consent already granted. The CMA has identified 46 individual transactions across the four deals, and is also examining whether wider “relevant merger situations” arise between Care UK and Aria Care, and between Apex Healthcare Properties and HC-One.
For a sector that has long relied on overseas capital – and on REITs in particular – to fund growth, recapitalise distressed portfolios and underwrite new development, this is a moment that demands close attention.
Why the CMA is interested in property, not just operators
The most strategically important feature of the CMA’s intervention is what it tells us about the regulator’s view of the modern care home capital stack. Welltower is not a care operator. It is a US-listed real estate investment trust (REIT), and on the face of the transactions it has acquired real estate, taken equity positions and converted legacy lending exposures into long-term ownership. In a traditional analysis, that might have sat comfortably outside merger control altogether.
The CMA has clearly taken a different view. Its concern is that the influence a major property owner can exert – through lease covenants, capex approval rights, refinancing triggers, redevelopment consents and, ultimately, the ability to determine which operator runs a given home at the end of a term – is material enough to count as a change in the locus of competitive decision-making. That is a notable expansion of how the CMA is willing to think about control and material influence in our sector, and it should reset expectations for anyone structuring a sale-and-leaseback, OpCo/PropCo split, or REIT-led roll-up.
The risks the ruling crystallises
Several risks now need to be factored into any UK care home transaction of meaningful size:
Deal certainty has materially weakened for large portfolios – the CMA’s willingness to investigate completed transactions, layer initial enforcement orders over them and unwind them at Phase Two means that closing is no longer the end of the regulatory story. Initial enforcement orders have already been served in respect of each of the four Welltower acquisitions under section 72(2) of the Enterprise Act 2002, requiring the businesses to be held separate while the investigation runs. Buyers should expect closer scrutiny of “hold-separate” obligations and the practical operational frictions that come with them.
Local market concentration matters more than national share – the CMA’s analysis focuses on competition at the level of individual catchment areas, not the national market. A buyer whose national footprint looks modest can still face problems where its homes cluster around the same towns. For mid-market consolidators, this means that deal screening needs to be done property by property, not at portfolio level.
Indirect or “creeping” combinations are now firmly in scope – part of what makes the Welltower investigation unusual is the CMA’s interest in whether the property arrangements give rise to merger situations between operators who, on paper, are unconnected – for example, between Care UK and Aria Care, and between Apex and HC-One. Anyone using a common landlord, common manager or shared services structure to assemble influence across nominally independent operators should expect the same lens to be applied to them.
Distressed and recapitalisation transactions are not immune – Welltower’s HC-One position was constructed in part through a loan originated during the pandemic that converted into equity. The CMA has not treated that structure as a reason for restraint. Lenders considering loan-to-own strategies, warrant-backed facilities, or restructurings that result in equity stakes should expect those routes to ownership to be analysed in exactly the same way as a conventional acquisition.
Timing and cost risk has increased – Phase One alone has taken almost four months on this matter, against a backdrop of statutory deadlines that can be extended. Phase Two, if it follows, is a far longer and more resource-intensive process. Parties contemplating a similar deal should now build in considerably more time and cost for competition clearance, even where the transaction has technically completed.
The opportunities – and why they are real
It would be a mistake to read the ruling as a closed door. The CMA’s process is calibrated to identify problem areas and address them through targeted remedies, not to halt sector consolidation. There are real opportunities here for well-advised parties.
Welltower and its partners have been given a window to offer legally binding undertakings, which in practice is likely to mean divestment of homes in specific local markets where overlaps are most acute. Those divestments create a near-term acquisition opportunity for regional and mid-market operators, family-owned groups and newer entrants who have been priced out of the larger processes over the last 24 months. The homes in question are, by definition, ones that the CMA has identified as needed for competition – which tends also to mean they are well-located, occupied and trading.
For investors, the ruling is also a reminder that the UK care market remains attractive enough to be the subject of record-breaking inbound capital. Welltower’s willingness to deploy more than £6 billion in this market in a short period reflects fundamentals – demographic demand, undersupply of high-quality stock, and a pricing gap between UK and US senior living – that have not changed. The regulatory recalibration may, if anything, support a more orderly pace of consolidation and reward operators who have invested in quality, governance and local reputation.
There is also a broader opportunity to shape the regulator’s thinking. The CMA has actively sought views from third parties, including other REITs, operators, local authorities, the Department of Health and Social Care, and the sector regulators in England, Scotland and Wales. Stakeholders who engage now – particularly on how property ownership, lease structures and operator selection actually work in practice – have a meaningful chance to influence the framework that will govern the next wave of transactions.
Practical takeaways for the deal table
For clients considering, structuring or financing UK care home transactions over the next 12 to 18 months, we would highlight five practical points:
Run a local-market competition screen at the earliest possible stage – ideally before heads of terms. The granularity of the CMA’s analysis means that conventional national-share thinking is no longer a sufficient filter.
Treat property-side transactions with the same competition rigour as operator-side ones. The structural label – sale-and-leaseback, real estate acquisition, refinancing with warrants – does not determine whether the deal is reviewable.
Build conditionality and risk allocation into transaction documents. Buyers and sellers should be explicit about who carries the cost and risk of CMA engagement, hold-separate obligations and any divestment remedies, including the financial mechanics of forced disposals.
Consider voluntary pre-notification for any large or strategically sensitive transaction. The Welltower experience demonstrates that completing without notifying does not provide a safe harbour, and that an initial enforcement order served post-completion is a meaningfully more disruptive outcome than a managed pre-clearance process.
Prepare an evidence base now. The CMA placed weight on internal documents, board papers, third-party data and operator commentary on competitive dynamics. Parties who can articulate their commercial rationale, local positioning and quality investment in a clear, documented way are in a far better position than those who cannot.
Looking ahead
The Welltower investigation is not, in itself, a verdict on inbound investment, REIT participation or sector consolidation. It is a signal that the CMA intends to apply its merger control powers across the full capital stack of the care sector, at a level of local granularity that we have not seen before, and that it is willing to do so even after transactions have closed. For operators, investors, landlords and lenders alike, the message is consistent: the deals will continue, but the road to closing has changed.
The next few months will be telling. Whether Welltower offers acceptable undertakings, what form those undertakings take, and which homes ultimately come back to the market will set the template for how large-scale care home transactions are structured for the rest of this decade.
