UK Banks are spending millions on digital. New research reveals it isn’t working.  

FOR IMMEDIATE RELEASE  

Remarkable’s Top 20 UK Banks Digital Maturity Report 2026 finds a sector investing heavily in visibility while neglecting the infrastructure that drives revenue – and a challenger bank leading the entire industry  

LONDON, 5 March 2026  – Customer experience consultancy Remarkable today publishes the Top 20 UK Banks Digital Maturity Report 2026 – a comprehensive independent analysis of digital marketing performance across the UK retail banking sector. The research reveals a widening gap between the millions being invested in Digital infrastructure and the outcomes those investments are producing.  

Twenty banks were assessed across ten dimensions, from strategic commitment and search performance to customer satisfaction and real-world switching behaviour. Every metric was drawn from independent third-party sources. No bank was asked to self-report.  

The headline finding is stark: a few banks are building scalable digital capability. The rest are incurring costs.  

Monzo leads the overall rankings, achieving a score of 73.7%. The challenger bank, which now serves more than 10 million UK customers, recorded 82% overall satisfaction and 87% satisfaction for online and mobile banking. Lloyds and Starling Bank rank second and third respectively. The results suggest challenger banks are no longer disruptors — they are increasingly setting the standard for digital banking performance. 

Five findings that every bank should pay attention to:  

1. The gap between digital investment and customer outcomes is wider than the sector acknowledges. HSBC and Barclays both score 100% on marketing technology. Both also score below 62% on customer satisfaction. Across the study, the correlation between what banks spend on digital and what customers feel is weaker than any boardroom should be comfortable with. Infrastructure is necessary. It is not sufficient.
2. Content has stopped working as a differentiator. Nineteen of twenty banks produce the same content formats at broadly comparable quality. When an entire sector converges on identical outputs, content ceases to generate competitive advantage and becomes a cost of presence. Monzo is the only bank in the study producing video content – a format that 19 of 20 of its competitors have declined to invest in despite clear consumer appetite for it.
3. Paid search is haemorrhaging budget at the top of the market. Paid search spending is rapidly increasing, but the returns are declining. Santander is estimated to spend £5.62 million per month on paid search, generating fewer than 45,000 clicks, which leads to a cost per click of over £100. In comparison, First Direct achieves almost 100,000 clicks from only 408 keywords, showing that targeted strategies can be more effective than larger campaigns.
4. Switching data exposes retention problems that satisfaction surveys do not. Several banks report acceptable NPS-like satisfaction scores but lose thousands of customers each quarter through CASS data. Santander lost nearly 20,000 net customers in Q3 2025 – the largest net loss in the study – while spending an estimated £5.62 million per month on paid search. Halifax lost over 17,000 in the same period. Meanwhile, Nationwide gained a net 41,000 switchers in Q3 2025, outperforming every high street bank and every digital challenger, suggesting its proposition is landing in a way its modest marketing spend does not fully explain. RBS carries an overall satisfaction score below 50% – the only bank in the study to fall below that threshold - representing a retention risk that no digital investment programme has yet resolved.
5. Nine banks are failing a basic legal standard on their websites. Nine out of twenty banks fail their Core Web Vitals assessment. Only two banks – Monzo and Santander – offer multilingual capabilities, leaving eighteen banks effectively inaccessible to the eight million UK residents who speak a language other than English as their first language. With the European Accessibility Act now in force, low accessibility scores are no longer a performance issue. They are a compliance one.  

For banks already investing heavily in digital transformation, the report raises an uncomfortable question: are those investments actually improving customer experience and retention? 

Paul Stephen, CGO of Remarkable, said:   

“UK banking has undergone more digital change in the past decade than in the previous fifty years combined. Branch numbers have fallen by over 40% since 2015. Mobile banking among adults under 55 has exceeded 80%. By every traditional measure, this is a digitally mature industry. What this report reveals is that the infrastructure banks have built to attract and convert customers has not kept pace with the transformation they have been announcing. The banks treating this report as a benchmarking exercise will find it useful. The banks treating it as a brief will find it transformative. The difference between those two responses is the same difference that separates the top five from the rest of the table.”
