Forward-looking behavioural intelligence for UK wealth managers and advisers. Tracking ISA accumulation, pension decumulation, cross-wrapper capital flows, and provider competition — powered by live market data.
Understanding where we are in the accumulation/decumulation cycle and what it means for advisory conversations and client outcomes.
The market is in a credit stress phase. Pension drawdown for debt paydown is at 4.2% and rising (+2.4pp MoM), indicating growing financial pressure on households. Capital is exiting the wealth system to service liabilities rather than building assets. Under-35s represent 31.4% of ISA users with 15.7% choosing Stocks & Shares, a growth accumulation signal that creates opportunities for advisory engagement with younger investors.
Debt-driven drawdown at 4.2% is an elevated financial stress signal. Users accessing pension capital to pay down liabilities indicates pressure on household balance sheets. This capital exits the wealth system entirely, reducing both pension assets and potential accumulation capacity. Capital preservation dominates: 84.3% Cash ISA preference and 42.4% accessing maximum tax-free lump sums. Capital is being held or released rather than deployed into growth assets. Pension pots (£444,947 mean) are 17.6x larger than ISA opening amounts (£25,332). Decumulation carries substantially more capital per user, making pension purpose signals (debt paydown, self-investment) high-impact indicators for the broader wealth market.

Data-driven answers to key questions about UK wealth, ISA markets, pension drawdown, and advisory intelligence.
UK household wealth encompasses the total financial assets held by individuals and families across the country, including savings, pensions, property, and investments. According to the ONS, total UK household wealth exceeds £15 trillion, with financial wealth (pensions, savings, investments) making up a significant portion.
For wealth managers and financial advisers, understanding household wealth trends is essential for client acquisition, retention, and competitive positioning. The Wealth Index tracks behavioural data across ISA accumulation and pension decumulation to provide forward-looking intelligence on how capital is flowing through the UK wealth landscape.
Based on 210 users sampled in February 2026, the Wealth Index recorded a mean opening deposit of £25,332. Across the captured sample, this represents approximately £5,319,619 in total ISA deposits for the month.
The wrapper split shows 84.3% allocated to Cash ISAs and 15.7% to Stocks & Shares ISAs, with S&S allocation rising 9.5pp month-on-month. HMRC reports that UK adults deposited approximately £80 billion into ISAs in 2023-24, underscoring the scale of the ISA market.
The UK ISA allowance for the 2025/26 tax year is £20,000 per individual. This covers Cash ISAs, Stocks & Shares ISAs, Innovative Finance ISAs, and Lifetime ISAs (with a separate £4,000 sub-limit).
From our February 2026 sample of 210 users, the mean opening deposit of £25,332 suggests savers are heavily utilising the full allowance. 58.1% of users sampled were first-time ISA holders, indicating ongoing market growth.
Approximately 22 million UK adults hold at least one ISA, with around 11 million subscribing (making new deposits) in any given tax year. Cash ISAs remain the most popular wrapper, though Stocks & Shares ISAs have seen growing adoption, particularly among younger investors.
The Wealth Index tracks ISA behavioural data monthly to identify shifts in provider preference, wrapper allocation, and new entrant trends. In February 2026, 58.1% of our sampled users were opening their first ISA, and 31.4% were under 35 years old.
Pension drawdown (also known as flexi-access drawdown) allows individuals to withdraw money from their defined contribution pension pot while keeping the remainder invested. Since the 2015 pension freedoms, drawdown has become the dominant method of accessing pension wealth in the UK.
From our February 2026 sample of 95 pension users, the mean pot size was £444,947 and the mean withdrawal age was 62.1. 42.9% of users adopted a sustainable withdrawal strategy aligned with the 4% rule, while 42.4% accessed their 25% tax-free cash entitlement.
UK pension holders can typically withdraw up to 25% of their pension pot as a tax-free lump sum from age 55 (rising to 57 from April 2028). This is known as the Pension Commencement Lump Sum (PCLS) and is capped at £268,275 for most individuals.
In February 2026, our data shows 42.4% of pension users accessed tax-free cash, representing an estimated £0 in captured capital exiting pension wrappers. When extrapolated to the UK's approximately 1 million annual drawdown entrants, this represents a significant capital flow that wealth managers should be tracking.
The Accumulation Index (currently 49/100) measures the strength of capital inflow behaviour across ISA deposits, new entrant growth, Stocks & Shares allocation, and contribution regularity. A higher score indicates stronger capital building activity.
The Decumulation Index (currently 51/100) measures the intensity of pension drawdown activity, including tax-free cash uptake, 4% rule adoption, and withdrawal age trends. Together, these indices form the Wealth Cycle — currently in the Credit Stress Phase — giving advisers a forward-looking view of where UK household capital is flowing.
Wealth managers and financial advisory firms use market intelligence reports to inform their client strategy, competitive positioning, and business development. Common use cases include:
The Wealth Index provides monthly intelligence packs, weekly pulse alerts, and prospect reports tailored to institutional subscribers.
AUM leakage refers to assets under management that are at risk of leaving an advisory firm's scope — through transfers to competitors, pension cash withdrawals, debt-driven drawdown, or rate-chasing behaviour.
The Wealth Index Leakage Score (currently 35/100, rated moderate) is a composite of transfer intent (7.1%), debt-driven pension drawdown (4%), tax-free cash uptake, and rate sensitivity signals. In February 2026, we estimated £444,948 in captured capital at risk across 95 pension users sampled.
The UK ISA provider landscape is dominated by a mix of high-street banks, building societies, and investment platforms. Based on our February 2026 behavioural data from 210 users sampled:
Provider rankings shift monthly based on rate changes, marketing campaigns, and seasonal trends. The Wealth Index tracks these competitive dynamics to help advisory firms anticipate platform migrations and switching behaviour.
In February 2026, 31.4% of ISA users sampled were under 35 years old. This cohort is increasingly important for wealth managers because younger investors tend to favour Stocks & Shares ISAs over Cash ISAs, show higher digital engagement, and represent a long-term accumulation opportunity.
Currently 15.7% of sampled ISA activity is in Stocks & Shares wrappers, and younger savers are disproportionately driving this allocation shift. Understanding the age profile of new entrants helps advisory firms build pipeline strategies for future AUM growth.
A wealth cycle describes the macro pattern of how household capital flows between accumulation (saving, investing, building wealth) and decumulation (spending, drawing down, redistributing). The Wealth Index identifies six distinct phases:
As of February 2026, the UK wealth cycle is in the Credit Stress Phase: The market is in a credit stress phase. Pension drawdown for debt paydown is at 4.2% and rising (+2.4pp MoM), indicating growing financial pressure on households. Capital is exiting the wealth system to service liabilities rather than building assets. Under-35s represent 31.4% of ISA users with 15.7% choosing Stocks & Shares, a growth accumulation signal that creates opportunities for advisory engagement with younger investors.
The Wealth Index analyses behavioural data from UK ISA and pension drawdown activity. All analytics are deterministic — there are no AI-generated opinions or LLM calls involved. Every metric, score, and insight is derived from observed user behaviour.
Data is processed through quality-checked pipelines with provider canonicalisation, outlier handling, and confidence scoring. Each monthly release includes a confidence score (0–100) reflecting sample size, data completeness, and statistical reliability. In February 2026, we sampled 210 ISA users and 95 pension users.
Market inferences (estimates of UK-wide trends) are clearly labelled as directional projections based on captured behavioural data, not actual market totals.

Capital is being released from pension wrappers at a faster rate than accumulation inflows. Cash ISA preference dominates at 84.3% of wrapper choices, softening month-on-month. Capital preservation behaviour remains the primary accumulation pattern. Pension drawdown for debt paydown at 4.2% is a financial stress indicator. Users are accessing retirement capital to meet current liabilities rather than funding income or growth. 42.4% of pension users are taking the maximum 25% tax-free lump sum, releasing an estimated £47,164 per user. Significant capital is exiting pension wrappers into liquid holdings. Withdrawal strategy is split: 42.9% follow the 4% sustainable rule while 57.1% use custom rates. The market is divided between systematic drawdown and flexible income approaches.
