Four ISA allocation solutions for under‑65 clients after the cash cut
Introduction
With the cash ISA allowance for under‑65s dropping to £12,000 from April 2027, while the overall £20,000 limit stays unchanged, advisers are entering a new era: one where clients who prefer certainty must now allocate at least £8,000 into investments if they wish to maximise their tax-free allowance.
For many, this shift is psychologically uncomfortable. And this is precisely where smoothed solutions - like Wesleyan’s Smoothed With Profits Growth fund - can become an anchor product in your advice framework.
Below are four re-engineered ISA allocation solutions.
1) Essential cash + Core smoothed growth
A default blueprint for risk-averse clients who’ve historically maxed cash.
How it works
- £12k Cash ISA
- £8k Stocks & Shares ISA
Preserve the client’s sense of safety and liquidity within the new restricted limit. Existing ISA cash remains tax-free and untouched.
Anchored by Wesleyan's Smoothed With Profits Growth fund, this creates a stable, low-volatility core for clients who would otherwise avoid investing but now must engage with it due to the new rules.
Why this solution works with a smoothed fund
The government openly intends for this policy to transition cash-heavy savers toward investment exposure.
A smoothed fund offers the ideal behavioural bridge:
- Reduces sharp price movements
- Offers a steadier growth path
- Gives previously cash-only clients a comfortable first step into investing
2) Laddered liquidity + Smoothed/equities blend
For clients who need structured liquidity but want incremental growth.
How it works
- £12k Cash ISA spread across maturities
- £8k Investment ISA, built as:
Instant access + 1–3 year fixed rates = predictable liquidity.
Core: Smoothed With Profits Growth fund
Satellite: Broad equity exposure (optional depending on risk)
Why this solution works with a smoothed fund
The policy is intended to reduce oversized cash positions and nudge long-term investing. However, many laddering clients aren’t ready to jump straight to full market volatility.
Your smoothed fund becomes the "first layer of growth":
- Offers better chance at stability
- Softens the behavioural jump to equities
- Helps preserve capital while targeting medium-term growth
It works beautifully for clients who want control over liquidity but still need their remaining ISA allowance to work harder.
3) House-deposit planner
For younger clients juggling security and inflation risk.
How it works
- £12k Cash ISA
- £8k Investment ISA
Important for near-term house deposit security.
Instead of exposing nervous buyers to full-equity risk, use the Smoothed With Profits Growth fund to provide:
a. Potential for gentle growth over inflation
b. A smoothing mechanism which aims to reduce volatility
c. A smoother experience during emotionally charged savings periods
Why this solution works with a smoothed fund
Committees and industry voices have questioned whether the cash-allowance cut will truly push younger savers into risk assets. But in practice, if they want to use their full ISA allowance, they must invest at least £8k.
Wesleyan's Smoothed With Profits Growth Fund offers many of the attributes house-deposit savers need:
- A middle ground between "too safe" and "too volatile"
- The potential to reduce inflation drag over multi-year time horizons
- A psychologically manageable investment experience
4) Pre-retirement de-risking
For late-50s to early-60s clients preparing for retirement decumulation.
How it works
- £12k Cash ISA
- £8k Investment ISA
Supports short-term retirement cashflow and near-access needs.
Under-65s must use this smaller cap until they reach 65, when the cash ISA allowance returns to £20k.
The Smoothed With Profits Growth fund becomes the natural core holding, offering:
a. Lower volatility than equities
b. More growth potential than pure cash
c. A smoother path in the final accumulation phase
Why this blueprint fits your smoothed fund
With rising tax on savings interest outside ISAs from 2027, advisers must help clients maintain tax-efficient growth without unwanted risk spikes.
A smoothed fund aims to address this need as a pre-retirement stabiliser - especially when clients are most loss-averse.
Why your Smoothed With Profits Growth Fund should be the "£8k answer"
Across all four blueprints, one truth emerges: When ISA cash is capped at £12k, advisers need a compelling, low-volatility investment option to absorb the compulsory £8k.
A smoothed fund could provide clients that are nervous about full equity exposure a growth pathway that feels familiar, controlled, and emotionally manageable - exactly what’s required in the post-Budget ISA landscape.
