  • Alex Kemp and Shane Lucas at Which were my mortgage brokers for an extremely difficult pair of BTL expat landlord mortgages (including one on a very very old property.) Despite the endless difficulties banks through in the way of these offers, both staff were the model of perfect brokerage: fast, efficient, informed, in total command of the facts, entirely capable of representing my position, often forcefully, to the banks.

What we charge

You won't pay for your initial consultation. If you decide that you'd like us to help with your application, we'll charge a fee of £499 to cover our administration costs.

This is paid in two parts:


A first instalment of £299 when we start. This fee is non-refundable and payable on application.


A second instalment of £200 once you complete your mortgage. If you're a full Which? Member when you first get in touch, this is £100 (this does not include temporary or trial membership).

*These amounts are subject to change. These charges apply to each mortgage contract you enter into through us. Once you've spoken to an adviser and provided details on your specific requirements, we'll confirm the exact fee to be paid and when it will be collected.

On most mortgage applications we receive a commission fee from the lender on completion. This is separate from our administration fee and is additional fee we receive.
