We contacted MAB following a recommendation. We were allocated a financial representative, Jason. Jason is a lovely guy. We felt we'd known him a long time; he immediately made us feel at ease, explained everything well and with clarity, no confusing jargon used. He was very pro active at dealing with our case. He was like our best friend during our enquiries and application. Always available at the end of the phone. He will very firmly remain in our contacts for any future need for financial advice.

Really happy with the service received by Sam, very helpful and knowledgeable. Helped us apply for our mortgage, although didn’t end up getting the best rate as was same time the war was going on in the Middle East so rates went up, just bad timing I guess. He is also setting up our life insurance etc so takes out the stress applying ourselves. Gives you honest opinions and good detail and keeps you up to date with everything.

Claire and her assistant Kayleigh have been incredible throughout my mortgage process. Claire guided me every step of the way, and even when small bumps came up, she was right there. She’s incredibly responsive, often replying the same day, and always supportive. Not only is she professional, but also warm and friendly truly amazing to work with! I highly recommend them.

This was our second time using Dominic Reddish for our re-mortgage. The service was fantastic from start to finish. Dom was friendly, knowledgeable and always quick to respond to any questions. He made the whole mortgage process feel straightforward and stress free. We would highly recommend Dom to anyone looking for a mortgage advisor.

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.
