Savers Losing £416 Annually as HMRC Deadline Looms This Weekend
Loyal cash ISA savers are being consistently penalised by holding their money in closed accounts that trail behind the highest rates by more than two per cent, according to new research from Moneyfacts. Financial experts warn that cash ISA savings are too often neglected and require active management, similar to investments.
The Cost of Inaction
Currently, savers are missing out on £416 per year by keeping their £20,000 cash ISA allowance in the average closed easy access ISA account at 2.49 per cent, compared to the top deal paying 4.57 per cent. This alert comes as the current tax year concludes on Sunday, April 5, with ISA allowances resetting on Monday.
Caitlyn Eastell, personal finance analyst at Moneyfactscompare.co.uk, stated: “Millions of savers could be missing out on hundreds of pounds annually by leaving funds in older, underperforming cash ISAs instead of switching to competitive accounts. While interest rates have risen, many loyal customers face penalties in ‘closed’ accounts that lag by over two per cent.”
She explained that providers often prioritise higher rates for new customers to attract fresh deposits, manage costs, or fund future lending. For instance, someone with £20,000 in an average closed easy access ISA earns just £498 yearly, versus £914 in a top account.
Expert Warnings on Financial Inertia
Financial experts emphasise that inertia is costing people significant money. Joe Farmer, Independent Financial Adviser at The Retirement Studio, said: “Doing nothing costs many people a lot of money. Reviewing your cash ISA is crucial when hundreds of pounds are at stake.”
He noted that ISA providers typically target new business with their best rates, and the loyalty penalty can be severe. “£416 is substantial, especially amid rising prices where every penny counts. Savers must ensure their money works as hard as possible.”
Philly Ponniah, chartered wealth manager at Philly Financial, highlighted the “set and forget” behaviour of many savers. “Cash ISAs feel safe, so people assume they’re sorted, but providers rarely reward loyalty. New customers get headline rates, while existing savers drift onto uncompetitive ones.”
She outlined two key points:
- Switching is low effort but high impact—moving £20k from 2.5% to 4.5% is a risk-free pay rise on savings.
- The wrapper matters—transferring preserves tax benefits, whereas withdrawing and redepositing can accidentally wipe out previous contributions.
“Cash savings need active management, just like investments. An annual check can differentiate between money standing still and keeping pace with inflation.”
Call for Active Management
Nouran Moustafa, practice principal and IFA at Roxton Wealth, stressed that active management is essential. “£416 isn’t just extra money; it’s what savers lose by leaving cash ISAs untouched. Many think ‘I have an ISA, job done,’ but accounts can become lazy and unfit for purpose.”
She advised savers to check rates, ensure competitiveness, and transfer properly without withdrawing to avoid disrupting the tax wrapper. “This is about basic self-protection. Leaving cash in a dead ISA isn’t loyalty—it’s letting money underperform while others benefit. With high costs, this isn’t a harmless mistake; it’s real money lost.”
With the new tax year approaching, experts urge savers to review their ISAs promptly to maximise returns and protect tax-free status, turning potential losses into gains through simple, proactive steps.
