Why London mortgages need a specialist

London property costs more than almost anywhere else in the UK, so loans are larger and lenders' affordability rules matter more. Many London buyers also have income that does not fit a simple payslip: bonuses, commission, contracting, company dividends or earnings from overseas. And much of London's housing is leasehold flats, new builds and converted houses, which some lenders treat more cautiously than others.

As a whole-of-market broker we compare high-street banks, building societies, specialist lenders and private banks, then present your case the way the right lender needs to see it.

Frequently asked questions

Yes. We are based in Mayfair but help clients in every London borough, as well as the rest of the UK and overseas buyers purchasing in London.

Do I need to come to your office?

No. Most clients never visit. We advise by phone, video and secure email, and lenders accept electronic documents and digital identity checks. You're welcome to meet us at 23 Berkeley Square if you prefer.

Can you help if I'm self-employed or have bonus income?

Yes. Lenders assess bonuses, commission, dividends, contract income and overseas earnings in different ways. We know which lenders look at the whole picture and how to present your income to them.

Can you arrange mortgages on leasehold flats and new builds?

Yes. Lenders have different rules on lease length, service charges, new-build deposits and some types of construction. We check these early so there are fewer surprises at valuation.
