My mortgage advisor is absolutely lovely! Cherry who I have met in person and had meetings with and Kate Gregory who I've had had email correspondence with have both been brilliant. They've been very kind and understanding supporting me through being a first time buyer with lots of questions and queries. I have received excellent customer service and am kept up to date on and during all developments by my preferred method quickly and with empathy and compassion during the stressful home buying process. They have both looked at alternatives for me when I raised issues with other parties and have generally been fantastic. I absolutely would recommend to others.

We would like to express our sincere thanks to Vimal for the fantastic service he has provided throughout our mortgage journey. we had very little knowledge of mortgages and the overall process. From the very beginning, Vimal made everything incredibly easy to understand and guided us through each step with patience and professionalism. He took the time to explain everything clearly, helping us feel comfortable, informed, and confident in the decisions we were making. Vimal went above and beyond to find the best options for us and was always available to answer questions, no matter how small. His knowledge and expertise made what could have been a stressful experience feel straightforward and manageable. Not only has Vimal been outstanding professionally, but he has also been a genuinely wonderful person to work with. His kindness, patience, and approachable nature immediately put us at ease, and it is clear that he truly cares about the clients he looks after. We honestly cannot fault the service we have received. The entire process has been smooth, well-managed, and reassuring from start to finish. We would highly recommend Vimal to anyone looking for mortgage advice and support.

Questions about our mortgage calculators

What are mortgage calculators?

Our mortgage calculators are digital tools designed to help you estimate your potential borrowing power and mortgage repayments. They’re a handy way of helping you understand your financial commitments before speaking to one of our expert advisers.

Is using our mortgage calculators right for you?

Our free digital tools are designed for anyone looking to purchase a home. This means if you’re a first time buyer, someone looking to move home, or you’re on the hunt for a remortgaging deal, our calculators are for you.

What information do I need to use a calculator and how does it work?

We have several handy calculators for borrowing, mortgage repayments, remortgaging, and Stamp Duty.

These all require two to three pieces of key information, which the calculators then use to provide you with an indication on what the potential costs could be.

Please remember that lenders also take a close look at other factors. These will include your credit score, financial history, and personal expenditures. All of this information will affect the actual calculation of your mortgage and monthly repayments.

Our mortgage calculators empower you to be as informed as possible when it comes to finding the right mortgage deal for you and your circumstances.

What are the next steps after using the calculators?

If you’d like to discuss moving forward with your homebuying journey, our expert advisers are here to help provide guidance and answer any questions you may have. You can also download the My MAB app, which allows you to save, plan, and track every stage of buying your new home and beyond.
