Having established a market-leading commercial mortgage offering in the UK, we are excited by the opportunities we are seeing both in the UK, as well across Europe – globally.

2025 has seen a marked uptick across both the UK and Europe in terms of refinancings and new loans. Whilst near-term macroeconomic volatility continues to weigh on transaction volumes, improving investor sentiment should support a meaningful market recovery.”
