Why UK Current Account Switching Still Takes Too Long

Seven Days That Feel Like Seventy

The Current Account Switch Service (CASS) launched in 2013 with a clear promise: switch your bank account in seven working days, with all direct debits, standing orders, and salary payments automatically redirected. It even came with a guarantee — if anything went wrong, the new bank would fix it and cover any charges. On paper, a solved problem. In practice, something rather different.

CASS has processed over 10 million switches since launch. That sounds impressive until you consider there are approximately 70 million current accounts in the UK. Annual switching rates hover around 3-4% — roughly the same as before CASS existed. The infrastructure works. The problem is everything around it.

What Actually Happens When You Switch

The mechanical process is genuinely good. You apply to open an account with a new bank, tick the CASS box, and the new bank initiates the transfer. On the switch date (day seven), your old account closes, payments redirect, and your balance transfers. The redirect service runs for 36 months, catching any payment that hits the old sort code and account number.

Where it breaks down is more subtle. Continuous payment authorities (CPAs) — the type of recurring card payment used by Netflix, Spotify, gym memberships, and subscription boxes — are not covered by CASS. These are linked to your debit card number, not your account details. When you switch, you get a new card, and every CPA fails. You must manually update each one. For the average UK adult with 6-8 active subscriptions, this is a ninety-minute administrative chore that nobody warns you about.

Then there are the edge cases. Joint accounts, linked savings, overdrafts with outstanding balances, and arranged overdraft facilities all complicate the switch. If your old bank offers a £2,000 arranged overdraft and your new bank approves only £500, you need to clear £1,500 before the switch completes — or the switch is delayed or cancelled.

The Emotional Switching Cost

Behavioural economists have studied banking inertia extensively. The FCA's 2022 Strategic Review of Retail Banking found that most non-switchers cite "hassle" as the primary reason — not loyalty, not satisfaction, just anticipated hassle. The reality is that CASS has reduced actual hassle significantly. But perceived hassle has barely moved. Banks have no incentive to promote switching (incumbents lose customers), and CASS's marketing budget is a fraction of what major banks spend on retention campaigns.

There is a deeper behavioural barrier: loss aversion. Your current account is a known quantity. Its app works a certain way, its overdraft limit is familiar, and its branch (if you use one) is on your commute. Switching means learning a new app, potentially losing an overdraft facility, and facing unknown customer service quality. The potential gain — maybe £100-£200 per year in interest or perks — does not emotionally outweigh the perceived risk.

Open Banking Was Supposed to Fix This

When Open Banking launched in 2018 under the CMA's Retail Banking Market Investigation Order, the vision was transformative: let customers share their financial data securely with any regulated provider, enabling instant comparison and frictionless switching. Eight years later, Open Banking has succeeded brilliantly at payments (Variable Recurring Payments, account-to-account transfers) but has barely dented switching inertia.

The issue is that Open Banking solved an information problem that was not the binding constraint. People do not fail to switch because they cannot compare accounts — comparison sites have existed for twenty years. They fail to switch because the act of switching carries real and perceived costs that outweigh the benefits. Open Banking made comparison easier. It did not make switching less annoying.

Smart Credit, Moneyhub, and other Open Banking-powered apps can show you exactly how much you would save by switching to a specific account. They surface this information proactively, with personalised calculations. Usage remains niche. The product works. Demand does not exist at scale.

What Digital Banks Got Right

Monzo, Starling, and Revolut sidestepped the switching problem entirely. Instead of asking customers to close their old account and switch, they said: open a second account. Use it for daily spending. Keep your old account for direct debits and salary. Gradually migrate at your own pace — or do not.

This "gradual migration" model has been enormously successful. Monzo has over 9 million UK customers, most of whom opened their account as a secondary spending account. Over time, many have made it their primary account — but without ever using CASS. The old account just becomes dormant.

The lesson for the industry is uncomfortable: CASS is a good solution to the wrong problem. People do not want to switch. They want to try. CASS is all-or-nothing. The future is probably incremental portability — moving one direct debit at a time, keeping both accounts open, with no hard cut-over date.

What Needs to Change

First, CPA portability. The Payment Systems Regulator should mandate that continuous payment authorities transfer automatically when a debit card number changes. The technical infrastructure exists — Visa and Mastercard both run account updater services that merchants can opt into. Making this mandatory rather than optional would eliminate the single biggest practical barrier to switching.

Second, partial switching. CASS should offer the option to move some direct debits and standing orders without closing the old account. The FCA floated this idea in 2019 and it went nowhere. It should be revived. Let people test a new bank with three direct debits before committing fully.

Third, overdraft portability. If you have a £1,500 arranged overdraft with Bank A and want to switch to Bank B, Bank B should be required to match or explain — not silently offer £0 and leave you scrambling. The FCA's overdraft reforms standardised pricing. They should standardise portability.

None of these changes are technically difficult. They are commercially inconvenient for incumbent banks, which is precisely why regulatory intervention is necessary. The UK has some of the best banking infrastructure in the world. It just needs to work for customers rather than around them.

Practical Advice for Switchers in 2026

If you are considering a switch, here is the honest playbook. Before initiating CASS: list every CPA on your current debit card (your banking app's transaction search is the easiest way — filter for recurring payments). After the switch, update each CPA manually. Budget sixty to ninety minutes for this.

Check your new bank's overdraft terms before switching, not after. If you rely on an arranged overdraft, get written confirmation of your facility from the new bank before initiating the switch. Do not assume it will match.

Consider keeping your old account open for three months rather than using the full CASS closure. Open the new account, redirect your salary, move direct debits manually over a few weeks, and only close the old account once you are confident nothing has been missed. This is slower than CASS but safer — and you avoid the CPA problem entirely because your old card stays active during the transition.

The best current accounts for switchers right now offer tangible incentives: Nationwide FlexDirect pays 5% AER on balances up to £1,500 for the first year. First Direct offers a £175 switching bonus with conditions. Chase pays 1% cashback on debit card spending with no cap for the first year. Whether those incentives justify the effort is a personal calculation — but at least now you know what the effort actually involves.
