What should a UK pension scheme ask first when selecting an asset manager?

Ask how the firm manages liquidity under stress, including collateral calls and dealing terms. Then ask how it reports costs, performance, and risks in a trustee-friendly format.

How do SDR labels change manager selection in practice?

They force clearer definitions of objectives, holdings rules, and ongoing disclosures. Buyers should test whether labels are consistent across factsheets, websites, and platform data feeds.

How can DC schemes access private assets without creating liquidity problems?

Use structures designed for less liquid holdings, and set realistic redemption notice periods and valuation timing. Also check how capital calls, cash buffers, and rebalancing are handled.

When is an active ETF a better fit than a mutual fund for UK wealth channels?

Active ETFs can fit model portfolios because they trade like listed instruments and simplify implementation. They work best when the strategy is repeatable and the cost is clearly justified.

What are the biggest operational red flags in LDI and leveraged fixed income sleeves?

Slow collateral processes, unclear authority to move assets, and weak stress testing routines are major red flags. Trustees should also confirm signatory readiness and escalation paths.

How should buyers evaluate platform-linked managers versus pure investment houses?

Platform-linked firms can influence fund visibility and flows through governance and product access. Buyers should separate platform economics from investment skill and confirm conflicts are managed.

Top UK Asset Management Companies

Legal & General Investment Management

Daily contributions keep UK workplace pensions grounded in steady flows rather than one-off mandates. L&G, a major player, noted that L&G Mastertrust reached GBP 30.0 billion in AUM in January 2025, which strengthens default design and pricing power for DC outcomes. FCA focus on SDR labels and clearer sustainability claims raises operational demands, yet L&G has been pushing private assets as a practical engagement lever for DC members since 2024. If DC defaults move faster into illiquids, L&G can benefit, but liquidity management during gilt stress remains a hard risk.

Leaders

Schroders

Momentum shows through even when buyers are cautious, so peak AUM matters as a signal. Schroders, a leading player, reported GBP 816.7 billion AUM at 30 September 2025 and described stronger net new business while launching an active ETF range in Europe. Policy shifts that steer DC and wealth channels toward private assets could support its Capital platform, though valuation and dealing terms will stay under scrutiny. The firm has also been vocal about tokenisation and blockchain as cost and process levers. If UK equities revive, it gains optionality, but execution risk rises if too many initiatives compete for attention.

Leaders

M&G Investments

Operational discipline now stands out as fee pressure persists and costs are scrutinized. M&G, a major player, reported GBP 345.9 billion AUMA at year end 2024 and pointed to cost savings targets through 2025. In product terms, M&G moved into active UCITS ETFs with UK listings and registrations, which can help it meet adviser demand for tradable wrappers. The FCA's sustainability labeling regime can reward firms that document outcomes clearly, but it also increases the cost of maintaining ranges. If rates fall, active fixed income demand could soften, so execution must stay balanced across public and private assets.

Leaders

BlackRock UK

ETF liquidity and low index costs remain central while stewardship expectations keep rising. BlackRock, a major player, shows sizeable UK-domiciled fund footprints, including an iShares UK equity index fund at about GBP 13.8 billion net assets as of 16 December 2025. BlackRock Investment Stewardship also published 2024-25 proxy year engagement and voting activity at scale, which matters for UK pension governance reviews. If FCA scrutiny on sustainability naming tightens further, product labeling and documentation will need fast updates. A realistic downside is political risk around ESG narratives spilling into client retention decisions.

Leaders

Vanguard Asset Services UK

Cost leadership delivers scale but can force abrupt platform choices when economics change. Vanguard cut fees across multiple ETFs in 2025, including further reductions announced in September 2025 for its UK Personal Investor ETF range. It also introduced a minimum monthly account fee for smaller portfolios, effective 31 January 2025, which changes its value story at the low end. If UK retail engagement grows through workplace defaults, Vanguard can benefit via index building blocks and model portfolios. The operational risk is service strain during inflow spikes, since low fees leave less margin for support.

Leaders

Insight Investment

LDI governance remains the core pressure point for many UK DB trustees, and Insight sits close to that control tower. It reports GBP 600.7 billion AUM and a top ranking for LDI and fixed income quality in its UK factsheet disclosures. A tighter stance from regulators on collateral readiness can favor firms with established playbooks, but it also raises the bar on reporting speed and cashflow forecasting. If sponsors accelerate buyout and run-on strategies, Insight can win transition and cashflow work. The main risk is a sharp rates move that tests liquidity terms and client confidence at once.

Established

Aviva Investors

Product design choices are now shaped as much by DC access rules as by pure investment views. Aviva, a major player, launched a Venture and Growth Capital LTAF in February 2025 with an initial commitment of about GBP 150.0 million from Aviva. The FCA's LTAF framework helps, yet the 0.75% DC charge cap still forces hard tradeoffs between fees, liquidity buffers, and manager lineups. Aviva has discussed expanding LTAFs beyond core pension channels, which could widen flows if platforms adapt. If private assets disappoint after fees, reputational risk could rise quickly in employer defaults.

Established

abrdn (Aberdeen Standard)

Brand reset can be practical when distribution teams need fewer distractions, and the firm has acted on that idea. The company moved back toward "aberdeen" branding in 2025 while reporting year end 2024 AUM of about GBP 511.4 billion and a sharp reduction in annual outflows versus 2023. UK retail flows increasingly run through platforms, so interactive investor strength can indirectly support fund selection and retention, even when active performance is mixed. If UK pension reforms push more consolidation, abrdn could benefit from being "good enough" across many sleeves. The risk is that further cost actions weaken investment bench depth at the wrong time.

Established

J.P. Morgan Asset Management UK

ETF innovation is shifting from passive replicas toward controlled tracking error designs. J.P. Morgan Asset Management expanded its active fixed income UCITS ETF range with the JPM Global IG Corporate Bond Active UCITS ETF, listing on the London Stock Exchange in May 2025. This matters for UK platforms and model portfolios that want daily liquidity with differentiated credit outcomes. If the FCA pushes harder on value assessments, active ETFs will need clear "why pay more" narratives. The what-if scenario is a rates shock that reverses inflows into credit, which would test the stability of newer wrappers and their seed capital.

Established

HSBC Asset Management

Management continuity often becomes visible only when a transition lands mid-cycle. The UK CEO of HSBC Asset Management was leaving, and the firm referenced a roughly USD 200.0 billion UK business being overseen. For UK institutional buyers, that scale can be reassuring, but governance questions rise during leadership change. If UK pension schemes accelerate delegation of decision-making to fiduciary providers, HSBC's banking relationships can help, though product differentiation must be sharper. The main risk is slow execution on operating model simplification across regions, which can affect speed to launch under new FCA rules.

Established

UBS Asset Management UK

Recent moves suggest an intent to modernize distribution rather than rely on legacy channels. UBS has been building out active ETF capability, including products with 2025 inception dates on its UK platform pages. It also recruited Sonja Laud from Legal & General, with a July 2026 start to co-lead its combined investments arm, reinforcing depth in public and private assets. If UK wealth models shift further toward ETFs, UBS can ride that structure, but scale in UK mandates still lags the largest incumbents. The key risk is execution complexity across multiple booking centers and fund domiciles.

Performers

Invesco UK

ETF development is becoming the fastest way to show innovation to UK wealth channels. Invesco launched the Invesco Global Enhanced Equity UCITS ETF in Europe with a London Stock Exchange listing in May 2025. It also restructured its UK equities capability into a broader Pan European team from January 2024, which can improve coverage but may weaken "UK specialist" messaging. If UK buyers rotate back into domestic equities, that earlier change could limit responsiveness. The key risk is talent retention during platform and team transitions.

Performers

Goldman Sachs Asset Management UK

Active ETF expansion is now a clear strategic bet for Goldman in Europe. Goldman Sachs Asset Management launched active equity ETFs in Europe with London Stock Exchange listings from April 2025, adding a visible distribution path for UK buyers. It also expanded active fixed income UCITS ETFs in 2025, reinforcing depth in tradable credit wrappers. If advisers continue replacing mutual funds with ETFs, Goldman can grow quickly despite a smaller UK base. A realistic risk is that ETF scale remains insufficient in stressed markets, which can expose liquidity optics early.

Performers

State Street Global Advisors UK

ETF platform plumbing is often invisible until it fails, and State Street leans into that role. The firm publishes regular stewardship activity reporting, which supports UK institutional governance needs. In December 2025, it also supported Dimensional's active UCITS ETF listings in London, showing strength in servicing complex ETF operations. If UK buyers demand private credit access in listed form, State Street's product partnership playbook could transfer, but liquidity optics will be sensitive. The main operational risk is cost pressure in a segment where fees keep compressing.

Aspirants

Baillie Gifford

Client concentration risk is getting more visible as pension pools reshape manager rosters. Baillie Gifford discloses GBP 208.0 billion in assets under management as of 30 September 2025, alongside a growing global office footprint. UK policy moves around LGPS pooling could pressure some external mandates, particularly where pool structures are being consolidated. If listed growth stocks recover strongly, performance could reassert brand pull with UK wealth buyers. The operational risk is dealing with higher redemption sensitivity while maintaining a patient investment style in less liquid holdings.

Aspirants

Fidelity International

Platform trust and product novelty both matter when retail investors compare wrappers side by side. Fidelity's UK site states 1.7 million customers and over GBP 40.0 billion of investments on its platform, which supports distribution leverage. It also pushed European active ETF boundaries with a semi-transparent structure, which can protect trading ideas but may confuse buyers used to daily holdings disclosure. If FCA consumer duty reviews tighten platform governance, fund due diligence and restrictions will become more frequent. A key downside is operational complexity when new ETF formats meet legacy platform rails.

Aspirants

Columbia Threadneedle

Range simplification signals discipline when smaller funds become costly to run well. Columbia Threadneedle's UK disclosures show multiple fund mergers and closures across 2024-2025, reflecting ongoing product rationalisation. It also adopted FCA SDR sustainability investment labels for several funds effective 24 March 2025, which raises documentation and monitoring expectations. If advisers keep moving to model portfolios, Columbia Threadneedle can win by being easy to slot into mandates with clear objectives. The risk is reputation damage if closures are read as retreat rather than focus.

Aspirants

Royal London Asset Management

Mutual ownership can encourage patience, but product clarity remains essential. Royal London reported record AUM of GBP 173.0 billion in its 2024 financial results page, driven mainly by positive markets. It also highlights UK sustainable funds using the FCA SDR Sustainability Focus label, which can help adviser conversations stay concrete. If DC defaults shift toward private assets, Royal London may need more partnerships to compete on breadth. The main risk is being squeezed between low-cost index providers and specialist private asset managers.

Aspirants

Impax Asset Management

Specialist positioning can win loyalty while it also raises mandate concentration risk. Impax reported GBP 26.1 billion AUM at 30 June 2025 and cited an added GBP 1.1 billion from completing an acquisition of European assets from SKY Harbor Capital Management. UK regulation around sustainability claims can suit Impax's focus, but it also raises the cost of proof. If UK pension schemes push harder into climate transition sleeves, Impax could recover flows. The key operational risk is maintaining investment performance while resizing teams and integrating new fixed income capability.

Aspirants

Jupiter Asset Management

Stability has been the main objective since a sharp reset in client flows. Jupiter saw net outflows of about GBP 10.3 billion in 2024 and AUM fall to GBP 45.3 billion, tied to the departure of a high-profile value team. In July 2025, Jupiter agreed to acquire CCLA Investment Management, which could diversify its UK client base toward charities and local authorities, subject to approvals. If integration goes smoothly, it can improve cost efficiency, but the risk is cultural mismatch that disrupts both brands.
