Mo is extremely professional and has helped me on multiple occasions with new mortgage and remortgage transactions for the past 3 years. I found MortgageTek and the team to be efficient, have constant communication with me every step of the way, and be outstanding plus helpful in resolving any issues that may arise along the way. I highly recommend MortgageTek for any future transaction as Mo always gets good rates

GORETTY DIAS
Customer
Would thoroughly recommend using Mortgagetek if you are a contractor. Mortgage applications are confusing enough as it is, so it’s great you can depend on the application being made smoothly by the team at Mortgagetek. Kate was excellent in keeping me updated and dealing with any questions I had. Will use them again.

Mo has helped me with multiple mortgage brokering both for new, remortgage and BTL transactions for about 4 years. I’ve found Mo and his team to be efficient, have clear and constant communication with me every step of the way, and very helpful to resolve any issues that may arise along the way. I unreservedly recommend MortgageTek.
