Our story

A trusted adviser, not a corporate bank

Quanstrom Financial was set up by Toby Quanstrom after more than a decade in mortgages, working first for high-street banks and then for a corporate brokerage.

Today we're a team of three, based in the centre of Eastbourne. As a whole-of-market mortgage broker, we compare lenders across the market and explain your options in plain English. We know our clients by name, we keep you updated, and the same small team looks after you from start to finish.

That's what Mortgages Simplified means to us.

How we work

What we believe in

  • Plain English, always

    No jargon and no small print surprises. If something isn't clear, we'll explain it again.

  • Whole of market for mortgages

    We compare lenders across the market to find a mortgage that suits your circumstances.

  • One team, start to finish

    You'll deal with the same small team throughout, and you'll always know where things stand.

  • Here for the long term

    We aim to get in touch before your deal ends, so you can review your options in good time.

Who we help

First-time buyers to complex cases

We love helping people buy their first home, and we're just as comfortable with cases that need a little more thought.

As a first time buyer I was very nervous about the process, and didn't know what to expect, but Toby made the process great and effortless.

James C.Google review, October 2026

Just bought our first home and couldn't have done it without Will. He is very friendly and knowledgeable, always happy to answer our questions and went the extra mile for us.

From start to finish I could not fault the service given by Toby and Jess … Toby made the whole process stress free!
