That resonates with me, especially when considering the competitive dynamics with larger banks. I would assume they have so much data that they could easily tweak some rules. For example, the Santander case you mentioned. They could adjust that rule and instantly tap into a market segment they weren't previously accessing. With a lower cost of funds, they could capture that market from challenger banks. You mentioned earlier that Barclays acquired Kensington, and it remains to be seen how that integration will unfold. In your experience, have you seen instances where high street banks adjust their decision-making to capture specialist product segments? Have they been able to do this effectively by tweaking their decision-making processes?

The last research I saw, which I think excluded buy-to-let, indicated an £18 billion market versus a £307 billion first charge residential, a pretty safe lending market. They'd rather compete over that than the £18 billion, which is aggregated from many niches. It's not just one product; some specialize in self-employed, others in different areas. That's the problem. It's an issue of scale for the very big banks.
