Santander Bank's 'Grand Finale' closes the six-year Bank of Antandec series with a choreographed musical number, marking the end of House 337's 20-year agency
Santander Bank Closes The Bank of Antandec With a Musical Farewell
Santander Bank's 'The Bank of Antandec: Grand Finale' is a 2025 United Kingdom television campaign in which the fictional rival banking executives played by Ant & Dec perform a choreographed rendition of 'New York, New York' as they concede defeat to Santander's Edge credit card cashback proposition, closing a six-year creative platform that spanned 15 campaigns.
The campaign launched across UK television on 13 September 2025, serving as the conclusive chapter of a series that began in 2019 and became one of British banking advertising's most recognised recurring creative vehicles. Created by House 337 with Merman Branded, in partnership with Mitre Studios, Carat and IPG, the Grand Finale marks not only the end of the Bank of Antandec platform but also the conclusion of House 337's 20-year agency partnership with Santander, as confirmed by coverage in marketing-beat.co.uk. The hero creative ran at 60 seconds, a format long enough to deliver the theatrical farewell the campaign's audience had come to expect.
The campaign's central proposition is Santander's Edge credit card, which offers cashback on everyday spending categories including supermarket purchases, fuel and travel. In the narrative logic of the Bank of Antandec universe, this cashback offering represents the competitive advantage that the fictional rival institution simply cannot match — the final straw that sends its two CEOs into a spirited, if chaotic, song-and-dance exit. According to Santander's Marketing Director Dan Sherwood, as quoted by marketing-beat.co.uk, the series has been an incredibly successful campaign vehicle that helped Santander connect with audiences in an entertaining and memorable way. Sherwood confirmed that Santander's relationship with Ant & Dec continues beyond the Bank of Antandec campaign itself, signalling a creative partnership that outlasts the specific platform it built. The Grand Finale earns a Clapboard Score of 62 out of 100, reflecting its strong entertainment craft and platform longevity weighed against the creative risks inherent in closing an established comedy format.
Santander Bank operates in one of the most crowded retail financial services markets in the world. In the United Kingdom, the competitive banking landscape is defined by scale players including Lloyds Banking Group and Barclays, both of which command substantial consumer brand recognition and significant mortgage origination volumes. According to mortgagesolutions.co.uk, Lloyds originated approximately £52.2 billion in UK mortgages in 2025, representing an 18.0 percent market share, while Santander's share increased from 6.5 percent to 8.6 percent across the same period — a gain that reflects the broader commercial momentum the brand has been building. Against this backdrop, the Bank of Antandec platform served a precise strategic function: it gave Santander a distinctive entertainment identity in a category where most communications default to reassurance, heritage, or rate-driven messaging.
Nick Pawlak, Client Managing Director at House 337, confirmed to campaignlive.co.uk that the Bank of Antandec ran for six years across 15 campaigns covering mortgages, current accounts, fraud prevention and financial education — a breadth of product territory that demonstrates how effectively the fictional rival bank device could be adapted to different messaging objectives without losing its tonal consistency. The Grand Finale concentrates specifically on the Edge credit card's cashback proposition, a product-level message that benefits from the accumulated goodwill and familiarity the series has generated across the UK market since 2019.
The strategic insight underpinning the series, and particularly this finale, is that British consumers respond to self-aware humour from financial institutions precisely because the category so rarely delivers it. Competitors such as Halifax have explored a music and entertainment register in their own UK advertising, but the Bank of Antandec's specific device — casting celebrity talent as the enemy who cannot compete — creates a comparative frame that is both memorable and commercially legible. As noted by eMarketer in coverage published on 16 September 2025, viewers developed genuine sympathy for the fictional executives over the course of the series, a phenomenon that speaks to the depth of audience investment the platform had accumulated. Closing with a musical concession rather than a simple product ad honours that investment while landing the Edge credit card's cashback advantage with clarity.
Guy Manwaring directed the Grand Finale. Manwaring is an award-winning director whose portfolio spans blue-chip UK and international brands including Amazon, Just Eat, Specsavers, Warburtons, McDonald's, Marks & Spencer and Halifax, and whose work has been recognised at Cannes, Kinsale and the British Arrows, as documented in Santander's own published campaign materials. His appointment to close the Bank of Antandec series signals the level of creative ambition Santander and House 337 brought to the finale — this was not a routine wrap-up execution but a considered piece of branded entertainment requiring precise choreographic and comedic timing.
The creative concept places Ant & Dec centre stage in a choreographed musical number set to 'New York, New York', performed in character as the departing CEOs of the Bank of Antandec. The execution is deliberately theatrical: the fictional executives go out in style, but things do not necessarily go to plan during their elaborate farewell performance, a detail that preserves the comic register the series has maintained since 2019. This controlled chaos — ambition undercut by gentle failure — is a creative signature consistent with the Bank of Antandec's tone across its 15-campaign run, which has included formats as varied as a comic reworking of MC Hammer's 'U Can't Touch This' for the 2022 fraud prevention instalment 'Stop! Scammer Time', as documented by moreaboutadvertising.com and santander.co.uk.
The production involved Merman Branded as the production company bringing the creative to screen, with Mitre Studios contributing alongside broader campaign partners Carat for media and IPG for wider campaign coordination. Josh Green, Chief Creative Officer at House 337, described the Bank of Antandec to campaignlive.co.uk as never just a campaign — a characterisation that the Grand Finale's production scale appears to substantiate. A 60-second hero format in a media environment where shorter forms dominate reflects a deliberate choice to give the series the send-off its audience relationship warranted, rather than compress the finale into a format optimised purely for efficiency.
No independently verified post-campaign performance metrics for the Grand Finale are publicly available at the time of writing. The campaign launched on 13 September 2025, and formal effectiveness data of the kind published by the IPA or verified through third-party measurement bodies had not entered the public domain prior to this analysis.
Structural indicators of effectiveness are, however, considerable. The Bank of Antandec platform ran for six years and 15 executions, a tenure that in the United Kingdom advertising market is almost impossible to sustain without demonstrable commercial returns. Santander's UK mortgage market share increased from 6.5 percent to 8.6 percent between 2024 and 2025, according to mortgagesolutions.co.uk, a period during which the Bank of Antandec was the brand's dominant creative platform — though direct attribution between advertising activity and market share movement would require formal econometric analysis not available in the public record.
Coverage from eMarketer published on 16 September 2025 noted that the series had generated genuine viewer sympathy for the fictional executives, a qualitative signal of unusual depth for a banking campaign in the UK market. Marketing-beat.co.uk framed the finale positively in coverage published on 16 September 2025, characterising Ant & Dec's farewell as the close of a popular six-year run. The decision by House 337 and Santander to conclude both the campaign series and a 20-year agency partnership simultaneously, as reported by marketing-beat.co.uk, suggests a planned and coordinated creative transition rather than a campaign that had exhausted its commercial utility. The Grand Finale's Clapboard Score of 62 out of 100 reflects strong entertainment craft and platform coherence, with headroom constrained by the inherent difficulty of closing an established format without measurable breakthrough beyond the series it concludes.
The Bank of Antandec Grand Finale is a 2025 UK television campaign for Santander's Edge credit card. Created by House 337 with Merman Branded, Mitre Studios, Carat and IPG, it closes a six-year, 15-campaign series featuring Ant & Dec as fictional rival banking executives who concede defeat with a choreographed musical number.
The Grand Finale launched across UK television on 13 September 2025, according to Santander's own published campaign materials. It marked the conclusion of the Bank of Antandec series, which had run continuously since 2019, spanning 15 individual campaigns covering mortgages, current accounts, fraud prevention and financial education.
Award-winning director Guy Manwaring directed the Grand Finale through Merman Branded. Manwaring has directed campaigns for Amazon, Just Eat, Specsavers, Warburtons, McDonald's and Halifax, and has received recognition at Cannes, Kinsale and the British Arrows, as documented in Santander's published campaign information.
The Grand Finale concluded both the Bank of Antandec platform and House 337's 20-year agency partnership with Santander, as reported by marketing-beat.co.uk. Santander's Marketing Director Dan Sherwood confirmed the brand's ongoing relationship with Ant & Dec continues, indicating the campaign closure reflected planned creative evolution rather than performance concerns.
The Grand Finale promotes Santander's Edge credit card. The card's cashback offering on supermarket, fuel and travel spending is positioned as the competitive advantage the fictional Bank of Antandec cannot match, providing the narrative trigger for the rival executives' musical concession and farewell performance in the 60-second hero execution.
House 337 led creative development alongside Merman Branded as production company and Mitre Studios as a production partner, as confirmed by Santander's published campaign credits. Carat handled media planning and buying, with IPG coordinating broader campaign activity across the United Kingdom launch in September 2025.
