Mergers, acquisitions, and consolidations continue to reshape the UK Wealth Advisory space. Among the recent standout deals are Nuveen’s $13.5 billion acquisition of Schroders, NatWest Group’s £2.7 billion purchase of Evelyn Partners completed in June, and Brooks Macdonald’s acquisition of LIFT-Financial Group and LIFT-Invest, adding £1.6 billion in assets under advice. In Q1 alone, Fairstone bought eight practices across England, Scotland and Northern Ireland, with the largest deal being West Midlands-based Prosperity Wealth in February, and they continue on that ambitious path. Citywire has described 2026 as one of the most active periods on record for UK wealth M&A, with no signs of slowing down.
Acquisitions are valued on the promise of scale, growth, and synergy. But in our view, that value is only realised (or lost) during integration. The deal itself is merely the starting point. Merging legal entities and balance sheets is one thing; providing cohesive customer experience post-acquisition is quite another. Each acquired business is often still running on its own platforms, following its own processes, and treating one customer differently from the next.
For a while, that complexity may be manageable. As the organisation grows, however, it starts to have a wider impact. Reporting takes more work because information resides in silos. Teams doing similar jobs may be following very different processes. Technology, outsourcing, and supplier costs overlap, while relatively straightforward changes must account for multiple systems and ways of working, with no ‘silver bullet’ fix.
These are just some of the hidden costs of integration and left unresolved, they don’t just make the organisation more complicated to run, they can hinder growth, reduce efficiencies, and affect the gains the acquisition was intended to create.
In our experience, realising the value from an acquisition depends heavily on having a clear strategy for how the businesses will operate as one entity, cohesively supporting its new larger pool of customers. That raises a number of considerations for how the businesses are brought together, some of which we’ve explored below.
Strategy before systems
If you’ve acquired several businesses running on different platforms, deciding which platform to keep can feel like the obvious starting point. For us, that decision comes later.
The starting point is strategic: what did the move set out to achieve, and what should the combined operating model look like as a result? Being clear on those outcomes gives the integration programme something concrete to work towards and, importantly, enables you to assess whether the expected benefits are actually being realised.
Choosing your technology stack too early risks designing the future organisation around the systems already in place. Before making that decision, leadership needs a clear view of how the combined organisation should function across people, process, and technology and the optimum experience for customers.
Before selecting platforms or planning migrations, firms need a clear view of how the combined business should operate. A Target Operating Model provides that blueprint, defining the processes, organisational structure, governance, customer experience and technology required to support future growth.
Integration doesn’t necessarily mean replacing everything that comes with the acquired businesses either. Part of the work is identifying what should be standardised across the organisation and what an acquisition has brought with it that’s worth retaining.
Without this clarity, firms risk replicating complexity rather than reducing it. Integration decisions should therefore focus on where standardisation creates efficiency and where retaining elements of an acquired business can strengthen the wider organisation.
Choosing a platform is only part of the consolidation
Platform rationalisation is likely to be high on the agenda when several acquired businesses are operating on different technology.
Choosing the right environment for the combined organisation means looking beyond cost and functionality. Scalability, integration capability, customer experience, vendor management, and existing contractual arrangements all have a bearing on the decision. Once that decision has been made, attention shifts to the migration itself.
Moving customers from one wealth platform to another can touch almost every part of the company. Account and customer data has to transfer accurately, existing integrations may need to be rebuilt or replaced, and operations teams need to be ready to work differently.
Successful migrations depend on careful planning, testing, risk management and stakeholder communication. The platform may be the destination, but the migration journey determines whether the transition succeeds.
For larger consolidations, migration may happen in stages rather than through one big move. That makes sequencing important: which customers or businesses move first, what needs to be proven before the next group follows and how the organisation will operate while old and new environments are still running alongside each other.
Looking at the migration as part of the wider integration programme helps teams see those dependencies early, including the impact on customer experience, operations, data, people, and delivery.
Look at the integration through your customers’ eyes
For customers, the internal structure of an integration programme means very little.
What they experience are the changes it creates. A familiar login process disappears, communications may look different or their adviser may start following a new process. Something that used to take two days might now take five, or they could find themselves providing information they’ve already supplied. Two customers dealing with what is now the same entity can receive completely different levels of service depending on which business they originally joined.
Customer journey mapping can help identify those differences before deciding what the future experience should be. Rather than looking only at where systems need to connect, follow the customer through the journey. Trace where their information moves, which teams become involved, where manual hand-offs happen and what changes when they move onto a different platform.
That view can expose integration issues that are easy to miss when the programme is viewed primarily through technology and operations.
For the customer, a successful integration should feel the same, or ideally, better. Their provider may be changing behind the scenes, but the confidence they have in the organisation shouldn’t suffer as a result.
Bringing businesses together also means bringing people together
Complexity increases with every acquisition. Each business introduces its own processes, technology, supplier arrangements and ways of working.
Organisations that integrate acquisitions against a clearly defined operating model can absorb new businesses more efficiently, reducing duplication and accelerating the delivery of acquisition benefits.
The Target Operating Model (TOM) should extend beyond processes and technology to encompass organisational design, governance and culture. Leadership needs to determine how responsibilities and accountabilities will be distributed across the combined business, how decisions will be made, and what capabilities will be required to support future growth. These are fundamental design decisions and should be considered an integral part of the TOM.
Think about who is going to deliver the integration
There can be a considerable gap between designing the future organisation and having the capacity to change it.
An integration programme will likely require business analysis, target operating model design, change management, platform expertise, data migration, customer journey mapping, supplier management, outsourcing model review, QA, testing, and delivery. At the same time, internal teams still have a business to run.
The mix of expertise required will change as the project progresses. A major migration may require testing expertise months before customers begin to move, while changes to roles and processes need change support well before the new operating model goes live.
Some of that expertise may already sit within the company, while specialist support might be needed intensively at particular stages. Fractional talent or outsourced support can also make sense where a capability is critical to the integration but isn’t needed permanently in-house.
Mapping that capability early gives the wider organisation a clearer view of what it can deliver internally and where additional expertise will be needed. Otherwise, specialist resources can end up being brought in when a critical migration, testing phase or operational change is already approaching, leaving far less room to plan properly.
Managing the complexity of a multi-acquisition strategy
There’s another reason to get integration right when multiple acquisitions form part of a longer-term growth strategy: the state of the organisation after one acquisition becomes the starting point for the next.
If platforms, processes, supplier arrangements, and organisational structures are still fragmented when another business is acquired, the next integration begins with that complexity already built in. Add another acquisition before resolving it and the problem compounds.
A defined operating model gives future acquisitions an end goal. The business already has a view of the technology architecture it’s working towards, how key processes should operate, where responsibilities sit and what the customer experience should look like. Each acquired business can then be assessed against that model, while still retaining anything it brings that genuinely improves the wider organisation. Over time, integration becomes a capability the business develops, rather than a new problem to solve after every deal.
An organisation that knows how to bring new businesses into its operating model can move towards the intended end state sooner and start realising the benefits of each acquisition without adding another permanent layer of complexity.
How can you maximise value?
The hidden cost of integration becomes much easier to see a few years after an acquisition: customers receiving different experiences, the same process working three separate ways, multiple platforms doing broadly similar jobs and teams still operating along the lines of the businesses they originally joined.
By that point, the organisation isn’t only carrying the cost of that complexity. It’s also carrying it into whatever change comes next.
For businesses pursuing an acquisition strategy, strategic operating model design and integration need to be part of the growth plan from the outset, with as much focus on realising value from each acquisition as there is on completing the deal itself.
