Centralised retirement proposition (CRP) and decumulation strategy — UK IFA guide

Take a client. Sixty-three, recently retired, a £640,000 pension pot, a £14,000 final-salary pension starting at 65, married, mortgage cleared, wants £36,000 a year drawn from the SIPP from day one to bridge the gap until her state pension and DB scheme kick in. She has the same attitude-to-risk score as one of your accumulating 45-year-olds. Same risk-profiler band. Same capacity-for-loss bucket on the standard questionnaire. If your CIP treats both clients the same way, the maths is wrong. The accumulating client benefits from a market fall — she's buying. The retiring client is destroyed by a market fall in year one — she's selling.

That asymmetry is the whole reason for a CRP. The CIP solution for a balanced accumulator doesn't fit a balanced decumulator, even when the headline risk metrics match. What follows is how firms build a proposition that reflects the difference.

What a CRP is

A CRP is a centralised proposition for decumulation. Same governance shape as a CIP — segments, solution set, due diligence, investment committee, ongoing review, Consumer Duty overlay — applied to the questions decumulation actually raises. The segmentation axes shift: a balanced accumulator and a balanced decumulator end up in different segments with different solution sets even though their risk-profiler scores match. The solution set expands to include guaranteed-income elements and structured drawdown approaches that don't appear in most accumulation CIPs.

The FCA expectation, set out across the regulator's Retirement Income Advice Thematic Reviewwork and the drawdown supervisory output, is that a firm advising clients in decumulation has a documented decumulation approach, that the approach reflects the specific risks of taking income from invested assets, and that the firm evidences ongoing review at a frequency suited to those risks (typically more often than annual in the early drawdown years).

The four risks a CRP has to address

Decumulation raises risks that don't bite in accumulation. A CRP has to address each one explicitly.

Sequence-of-returns risk.The order in which returns arrive matters when withdrawals are being taken. A 30% fall in year one with a recovery in year five is fatal in drawdown; the same fall in year five followed by a recovery in year one would have been recoverable. Average returns over the period can be identical and the outcomes opposite. The CRP needs a stated approach — cash buffers, bucketing, drawdown rules that vary with portfolio performance.

Longevity risk.The client may live materially longer than the planning horizon assumed. UK ONS data shows a 65-year-old man today has a one-in-four chance of reaching 95; a 65-year-old woman one-in-three. Planning to a fixed age is a category of risk. The CRP needs to state how the firm thinks about this — does it default to age 99? Does it stress-test withdrawals to age 100? Does it use longevity-pooled solutions for part of the portfolio?

Inflation risk.Real income, not nominal. A 4% withdrawal from a £500,000 pot looks similar in year one and year fifteen on paper; in real terms it's not. The CRP needs to state the inflation assumption and the indexation logic used in cash-flow modelling, and the rebalancing rule that protects real-terms income.

Withdrawal-strategy risk.The interaction between the chosen withdrawal pattern and the underlying portfolio. Fixed-pound withdrawals (taking the same £36,000 every year) behave differently from variable-percentage withdrawals (taking 4% of current value every year), which behave differently from guaranteed-floor-plus-upside strategies. The CRP needs to identify which strategies it deploys, and for which segments.

Strategy options inside a CRP

The decumulation strategies actually in use across UK IFA firms cluster into a handful of named approaches. A CRP usually deploys two or three, mapped to segments.

Bucketing.The portfolio is split into pots by time horizon. Bucket one is cash or near-cash for two to three years of expected withdrawals. Bucket two is short-duration fixed income for three to seven years. Bucket three is growth assets for the long horizon. Withdrawals come from bucket one; buckets are refilled from below as markets allow. The strategy is intuitive for clients and contains sequence-of-returns risk; the cost is a drag on long-term returns from the cash allocation.

Total-return drawdown.The portfolio is constructed as a single risk-targeted whole; withdrawals are taken as a percentage of current value with rules for adjusting in response to drawdowns. Lower cash drag, more reliance on the withdrawal rule. Variants include Guyton-Klinger guardrails and the simpler "if portfolio is below starting value, reduce withdrawal by X%" rule.

Annuity-floor-plus-flexible.A portion of the pot buys a lifetime annuity that covers essential income; the remainder runs as flexible drawdown for discretionary spending. Manages longevity and sequence-of-returns risk on the essential floor; preserves flexibility on the rest. Underused in the UK relative to the academic case; firms that include it in the CRP solution set need to evidence the annuity-rate analysis and the client suitability for partial annuitisation.

Natural yield.Withdrawals are taken from portfolio income (dividends, distributions) without dipping into capital. Suits clients who want capital preservation as a stated objective. The constraint is income volatility — yield isn't a smooth stream — and the tax inefficiency in unwrapped portfolios. Inside an SIPP wrapper, more workable.

Hybrid / GAR-with-drawdown.For clients with legacy pension policies carrying guaranteed annuity rates, the maths of partial conversion needs explicit treatment in the CRP. The default assumption that "drawdown is always better" doesn't hold when the GAR rate is materially above current market rates.

The safe withdrawal rate question for the UK

The familiar 4% safe withdrawal rate originates from US data over a US asset-allocation history. Direct application to a UK client base is questionable. Three issues:

First, UK long-run real equity returns have been lower than US — Dimson, Marsh and Staunton's Credit Suisse Global Investment Returns Yearbookconsistently puts the UK figure below the US one over the long run. A withdrawal rate calibrated to US returns over-estimates sustainable income from a UK-asset-allocated portfolio.

Second, the 4% rule was calibrated to a 30-year horizon. Many UK clients in drawdown are working to a longer or shorter horizon; the figure shifts in both directions.

Third, the original work assumed a static asset allocation and fixed real withdrawals. Real CRP strategies vary withdrawals based on portfolio performance; the equivalent sustainable rate with dynamic withdrawals is materially higher.

Pragmatic CRP practice: stress-test withdrawals using cash-flow modelling (Voyant, Timeline, CashCalc) across stochastic return paths, present clients with the probability of running out at chosen rates, and document the rate the client opted for with the reasoning. The "4% rule" doesn't appear in defensible suitability reports as a justification on its own; the cash-flow output and the stress-test scenarios do.

What the FCA's drawdown work asks for

The regulator's drawdown thematic and consultation work, including Retirement Outcomes Reviewoutput and subsequent supervisory output, lands consistently on the following expectations:

• Documented decumulation strategy per client, with cash-flow modelling output retained as evidence
• Ongoing review at a cadence appropriate to drawdown — six-monthly in the early years is increasingly the supervisory expectation, annually only when the client's circumstances are stable
• Explicit consideration of guaranteed-income solutions (including the FCA's pathway to considering annuities), with the reasoning for not recommending an annuity if that is the conclusion
• Sustainability monitoring — does the current withdrawal rate still look sustainable given the portfolio path?
• Vulnerability flags specific to drawdown clients (cognitive decline, bereavement, changes in care needs)

The Consumer Duty overlay on this is direct. Clients in decumulation are by definition in a phase where harm from bad advice — running out of money in their 80s — is asymmetric and largely unrecoverable. The duty's "avoiding foreseeable harm" rule and the support-and-understanding outcomes apply with particular weight.

How a CRP fits with a CIP

Most firms run a single proposition document that contains both — the CIP for accumulation segments, the CRP for decumulation segments — with shared governance and separate solution sets. Clients moving from accumulation to decumulation cross an explicit boundary: a documented review, often a meeting, the choice of decumulation strategy, the re-segmentation, the rebuild of the investment solution for the new phase. The mistake firms make is treating the transition as a quiet rebalance rather than the explicit re-anchoring it needs to be.
