Do you actually need a broker to remortgage?

Not always, and it’s worth being honest about that. If your income is a straightforward salary, your property is standard, your credit is clean, and you’re happy with your current lender, a product transfer arranged directly with that lender can be quick and perfectly sensible. You won’t always need advice to do it.

A broker earns their place when any of the following apply: you want to compare the whole market rather than take one lender’s offer, your income isn’t a simple payslip, your circumstances have changed since your last mortgage, you’ve been declined before, or you simply don’t have the time or confidence to weigh up the options yourself. The more boxes you tick, the more a broker is worth using.

How to check a broker is properly qualified and regulated

This is the one non-negotiable, and it takes two minutes. Every legitimate UK mortgage broker must be authorised and regulated by the Financial Conduct Authority (FCA), either directly or as an Appointed Representative of a regulated network.

Here’s how to check:

• Search the FCA Register at register.fca.org.uk. Type in the firm’s name and confirm they appear, and that mortgage advice is within their permissions.
• Understand the two models. A firm is either directly authorised by the FCA, or an Appointed Representative (AR) of a larger principal network that oversees their compliance. Both are legitimate. An AR isn’t a lesser status, it just means a principal firm supervises their regulatory standards.

• Check the adviser is qualified. UK mortgage advisers should hold CeMAP (the Certificate in Mortgage Advice and Practice) or an equivalent recognised qualification.

• Look for a clear complaints process. A regulated firm must have one, and must tell you about your right to escalate to the Financial Ombudsman Service if things go wrong.

If a firm isn’t on the FCA Register, walk away. There is no good reason to use an unregulated firm for something as significant as your mortgage.

Whole of market, tied, or limited panel?

Brokers differ in how much of the market they can actually access, and this matters more for complex cases than simple ones.

• Whole of market means the broker can consider products from across the lender market, which gives you the broadest range of options. This matters most when your case needs a lender outside the mainstream.
• Panel or limited means the broker works from a set list of lenders. Fine for straightforward cases, but potentially limiting if your situation needs a specialist lender that isn’t on their panel.
• Tied means the adviser represents a single lender. You’re only seeing one lender’s deals, which is rarely ideal for a remortgage where comparison is the whole point.

For a remortgage, and especially a complex one, whole-of-market access is worth prioritising. If a lender that suits your circumstances isn’t available to your broker, it doesn’t matter how good the broker is.

How mortgage broker fees work

Broker fees vary widely, and how a broker is paid is something you should always establish up front. There are three common models:

• Fee-free. The broker charges you nothing and is paid by the lender (a procuration fee) when your mortgage completes. This is standard industry practice and doesn’t affect your rate.
• Fee-charging. The broker charges you a fee, sometimes a few hundred pounds, sometimes over a thousand, often in addition to the lender procuration fee. Fees may be higher for complex cases.
• A mix. Some brokers charge a fee only on more complex work and waive it on straightforward cases.

A fee-charging broker isn’t necessarily better or worse than a fee-free one. What matters is that you understand exactly what you’ll pay and what you’re getting for it before you commit. Ask the question early, and get the answer in writing.

When you need a broker with complex income expertise

This is where broker choice stops being a formality and starts genuinely affecting the outcome. Lenders assess anything other than a simple PAYE salary very differently from one another, and the wrong lender choice can mean a smaller loan, a worse rate, or an outright decline. You want a broker experienced with your specific income type if you are:

• Self-employed, whether a sole trader, in a partnership, or running a limited company

• A company director taking a low salary plus dividends, where some lenders will assess retained or net profit and others won’t

• A contractor paid on a day rate, where specialist lenders can underwrite on the rate rather than your accounts

• Earning variable income through commission, bonuses, or irregular work

• Juggling multiple income streams, such as employed plus self-employed earnings

Two brokers can take identical figures and produce completely different results purely on which lenders they approach and how they present the income. If your last remortgage was a struggle, this is usually why. A broker who handles complex income daily knows which lenders treat your situation favourably before a single application goes in.

When you need high-net-worth or private bank expertise instead

It’s worth being clear that very high-value and ultra-complex wealth cases are a distinct specialism, and the right broker for them isn’t always the same as the right broker for complex income. You may need a broker with private banking relationships if you are:

• Borrowing roughly £1m or more, where private banks and bespoke underwriting come into play
• Looking to borrow against an investment portfolio (Lombard lending) or other assets rather than income

• Dealing with significant offshore income, trust structures, or foreign currency wealth

• Holding substantial assets but modest declared income, where lending is built around your overall wealth rather than a salary figure

Questions to ask a mortgage broker before you commit

A short list to run through on a first call. The answers tell you quickly whether a broker is right for you:

• Are you whole of market, or do you work from a panel?
• Are you fee-free, and if not, what will I pay and when?
• Have you handled remortgages for someone with my income type before?
• Will you compare my current lender’s product transfer offer against the wider market?
• Who will I actually deal with, and how will you keep me updated?
• What happens if my circumstances are tricky and the first lender says no?

Red flags to watch for

A few things that should give you pause:

• The firm isn’t on the FCA Register, or can’t tell you their regulatory status clearly
• They push you toward a decision before understanding your situation
• They’re vague about fees, or fees only become clear late in the process
• They only offer one lender or a very narrow panel for a remortgage
• They make guarantees about rates or approval before reviewing your circumstances, which no legitimate broker can do
