ISA Transfer: What to Check Before Moving Providers

Why this matters when choosing a broker

A receiving provider does not have to accept transfers in. It can also limit the ISA types, transfer scope, investments, markets, share classes, or routes it accepts.

Cash and in-specie transfers create different practical effects. A cash route can involve sales and time outside the market. An in-specie route depends on both providers supporting the same holdings and can restrict dealing while assets are re-registered.

This guide explains transfer checks. It does not recommend a transfer, sale, withdrawal, investment, ISA type, provider, or personal tax treatment.

How does the official ISA transfer process work?

The receiving ISA provider starts the process. GOV.UK directs a person switching providers to contact the provider they may move to and complete its ISA transfer form. HMRC's manager guidance says the new manager then deals with the existing manager and that the money and investments move directly between them.

A direct provider-to-provider ISA transfer can preserve the tax benefits of the wrapper. The transferred amount is not a new subscription for the overall ISA subscription limit. Withdrawing money yourself and paying it into another account is not the official ISA transfer process. HMRC treats money or investments sent to the investor as a withdrawal, which can remove them from the tax-free wrapper.

• The receiving provider must accept the ISA type and proposed transfer route.
• The account name, address, National Insurance number, existing provider, and account reference need to match the records requested on the form.
• The transfer authority needs to state whether the request covers all or part of the ISA and whether investments, cash, or both are included.
• Lifetime ISA and Junior ISA transfers have extra restrictions and are outside this general stocks and shares ISA checklist.

How are current-year and previous-year savings treated in an ISA transfer?

Current HMRC guidance allows some or all of the current tax year's subscriptions and some or all of previous tax years' subscriptions to be transferred. The associated investments and income move with the relevant subscriptions. MoneyHelper notes that the rules changed in 2024, so older articles that say all current-year subscriptions must move are no longer a reliable statement of the general rule.

The distinction still matters to the paperwork and provider process. ISA managers identify current-year subscriptions, previous-year subscriptions, and whether any current-year amount remains with the old manager. A provider can support fewer options than the rules allow, so full and partial transfer support needs confirmation from both providers. A transfer does not itself use the current year's overall ISA subscription limit.

Cash or in-specie ISA transfer: what changes?

In a cash transfer, investments are sold and the proceeds move as cash within the official ISA transfer process. The cash is not exposed to later market rises or falls between sale and any later purchase. This period outside the market can help or hurt depending on prices. Sale, settlement, transfer, and any later purchase can also create separate delays and costs.

In an in-specie transfer, also called re-registration, investments move without being sold when both providers can support them. This can keep the holdings exposed to market movements, but it does not guarantee uninterrupted dealing. Providers can restrict buying or selling while assets are being re-registered, and each holding may complete at a different time.

Unsupported assets are a route decision, not a minor detail. The exact security, exchange, currency, share class, and whole or fractional quantity can matter. Fidelity's current ISA transfer page, for example, says holdings it cannot offer may be sold and moved as cash. That provider example is evidence of a possible condition, not a rule for every platform or a suggestion to sell.

Which ISA transfer fees and timing claims need checking?

A displayed full transfer-out fee is only one cost field. The old provider may distinguish full and partial transfers, cash and in-specie routes, account closure, each investment line, overseas holdings, paper certificates, fund conversions, sales, and residual cash. The receiving provider may have separate incoming, dealing, conversion, or plan charges. A published £0 transfer fee does not prove that every related action is free.

Timing is provider-dependent even though GOV.UK publishes transfer deadlines. AJ Bell's current timing page illustrates the variation: it gives different typical ranges for cash, shares, funds, and international shares, and says the existing provider's response and outstanding costs can affect progress. Fidelity also publishes different ranges for cash and investment transfers. These estimates are provider examples, not promises for another provider pair.

• Record every charge from the old provider and the receiving provider, including the currency and whether it applies per account or per holding.
• Keep a transfer-out fee marked unknown when it is not published. Do not convert missing information to £0.
• Separate one-off transfer costs from recurring platform, dealing, fund, and foreign exchange charges after the transfer.
• Ask what starts the provider's clock and what can pause it, such as mismatched details, unsettled trades, dividends, fees, asset conversions, overseas forms, or manual paperwork.
• Treat residual cash, dividends, and later payments as separate completion items rather than assuming every item arrives together.

What should be verified before an ISA transfer starts?

A comparison is ready for review only when the proposed route can be described without filling gaps with assumptions. The receiving provider's current transfer page, form, permitted-investment list, fee schedule, and ISA terms should agree with the old provider's exit terms. Conflicts and missing facts remain visible until a provider confirms them.

• ISA type and receiving eligibility, including any extra Lifetime ISA or Junior ISA rules.
• Full or partial scope and the treatment of current-year and previous-year subscriptions.
• Cash, in-specie, or mixed route, including who handles any sale or conversion.
• Support for every security, market, currency, share class, and fractional position.
• Trading restrictions, open orders, unsettled activity, regular instructions, and cash needed for charges.
• Outgoing and incoming fees, per-holding costs, dealing charges, conversion costs, closure terms, and any exit penalty.
• Provider-specific timing estimate, transfer tracking, complaint route, and handling of residual cash or income.
• The checked date for each official page and whether any material term is unpublished, conditional, or stale.
