What makes a good mortgage broker?
A good mortgage broker is independent, qualified, experienced with your type of case, and transparent about their fees. More specifically, there are four things you should look for:
1. Whole-of-market access
The single most important factor. A whole-of-market broker can access every lender in the UK market — including exclusive broker-only rates not available directly to the public. A tied broker or panel broker is limited to products from specific lenders, which means you're not getting the best deal available. Always ask: "Do you have access to the whole market?"
2. FCA authorisation
Every mortgage broker in the UK must be authorised and regulated by the Financial Conduct Authority (FCA). You can verify any broker's status at register.fca.org.uk. If a broker isn't on the register, don't use them — full stop. All Nesto-matched advisers are FCA-regulated.
3. Relevant experience
Mortgage brokers tend to specialise. Some are excellent for straightforward residential purchases and remortgages. Others are specialists in bad credit cases, self-employed applicants, buy-to-let portfolios, HMOs, bridging finance, or large loans. The right broker for your situation is one who has extensive experience with cases like yours — not just a generalist.
4. Fee transparency
Many mortgage brokers are fee-free, earning commission from the lender only when your mortgage completes. Others charge a flat fee (typically £300–£500), a percentage of the loan, or both. There's no right or wrong structure — but a good broker always discloses their fees clearly before you commit to anything. Ask upfront: "How do you charge, and how much?"
How to find a mortgage broker in the UK
There are three main ways to find a mortgage broker in the UK:
Recommendation. If someone you trust has recently used a broker and had a good experience, that's valuable. But their situation may be very different from yours — what worked for them may not be the right fit for your case.
Online search. Searching "mortgage broker near me" or "best mortgage broker UK" returns hundreds of results. The challenge is knowing which firms are genuinely whole-of-market, which are tied, and which are experienced in your specific situation. Most people can't tell from a website alone.
A matching service. This is what Nesto does. We take your situation and match you with an FCA-regulated, whole-of-market broker who has experience with cases like yours. It takes two minutes and costs nothing. Rather than picking a broker at random, you get one matched to your specific needs.
Questions to ask before using a mortgage broker
Before committing to any broker, ask these questions:
- "Are you whole-of-market?" — If no, find out which lenders they can access.
- "How do you charge, and how much?" — Fee-free or fixed fee; what's included.
- "Have you arranged mortgages for people in my situation before?" — Self-employed, bad credit, large loan, HMO, etc.
- "How long does the process typically take?" — For your type of application.
- "Who will I be dealing with throughout the process?" — You or a junior team member.
Red flags to watch for
Avoid brokers who: can't confirm their FCA authorisation; won't tell you their lender panel; pressure you to apply quickly without fully understanding your situation; recommend a product without explaining why it's the most suitable; or charge a fee before doing any work.
