How to choose a mortgage broker or adviser you can trust

To choose a mortgage broker you can trust, check the firm on the FCA Financial Services Register before your first appointment, confirm in writing whether the adviser is whole of market, panel-based or tied to one lender, and ask what you will pay and when. A trustworthy adviser will tell you their fee up front, explain how they are paid by lenders, and give you an ESIS illustration for any product they recommend.

Mortgage advice in the UK is a regulated activity. The firm giving you advice must be authorised by the Financial Conduct Authority, or be an appointed representative of a firm that is. That is not a formality. It is what gives you access to the Financial Ombudsman Service if the advice turns out to be unsuitable, and it is the single fastest thing you can verify yourself.

Go to the FCA Financial Services Register and search the firm name. Check three things. First, that the firm exists and is currently authorised rather than showing as no longer authorised. Second, that the permissions include advising on and arranging regulated mortgage contracts. Third, that the trading name you were given actually appears against that firm, because many advisers trade under a brand name that differs from the legal entity.

If the adviser is an individual within a larger network, they may appear as an appointed representative rather than a directly authorised firm. That is normal and perfectly legitimate. What is not normal is a firm that cannot tell you its FCA reference number when you ask. That question takes ten seconds to answer and any real adviser answers it without hesitating.

Reviews are useful, but treat them as secondary. A five star average tells you people liked the experience. It does not tell you the firm was authorised to give the advice.

This is where most confusion sits, and it materially affects which deals you see.

• Whole of market means the adviser can consider products from across the residential mortgage market, though almost every firm excludes lenders who only deal direct with borrowers.
• Independent has a stricter meaning under FCA rules. It requires the adviser to consider a comprehensive range of products and not be limited in a way that biases the recommendation.
• Panel means the firm works from a defined list of lenders. That list might be forty lenders or it might be nine. Both are called panels.
• Tied or single-lender advice means you are being recommended products from one lender only. Bank branch advisers are the obvious example.

None of these is dishonest. A good panel adviser with thirty lenders will serve most borrowers well. The problem is when a panel firm markets itself using language that implies full market access. Ask the direct question: how many lenders can you actually place my case with, and which significant lenders are not available to you? Write the answer down.

Most people ask about rates. Rates change weekly and are largely outside the adviser's control. The questions worth asking are about process and constraints.

• What will you charge me, when is it payable, and is it refundable if my application is declined?
• Are you paid a procuration fee by the lender, and does that vary between the lenders you recommend?
• Which lenders do you place most of your cases with, and why?
• Have you placed cases like mine recently? Describe your income, credit history or property type honestly here.
• Who will actually handle my case day to day, you or an administrator?
• What happens if my offer expires before completion?

The last one matters more than people expect. Mortgage offers commonly run for three to six months. On a new build purchase or a slow chain, expiry is a real risk, and you want an adviser who has handled an extension or a re-offer before rather than one who has never met the situation.

Say you are buying at 320,000 pounds with a 10 percent deposit, so a 288,000 pound loan.

Adviser A charges no client fee. They are paid a procuration fee by the lender, commonly around 0.35 percent of the loan, which on this case would be roughly 1,000 pounds. Their panel covers twenty-two lenders.

Adviser B charges 495 pounds payable on offer, plus the same lender procuration fee. They advertise whole of market access and have placed several cases with lenders that assess self-employed income on one year of accounts.

If your income is a straightforward employed salary with payslips, Adviser A is likely to reach the same answer for nothing. If you are two years self-employed with a rising profit line, Adviser B's wider access could be the difference between a decline and an offer, and 495 pounds is a small price for that. The right choice depends on your case, not on which fee model sounds better in the abstract.

Some warning signs are obvious. Others are subtle and easy to rationalise when you are stressed about a purchase deadline.

• Pressure to pay a large fee before any advice has been given or any illustration produced.
• Refusal to put the fee in writing, or a fee that changes once you are committed.
• Any suggestion that you overstate income, understate credit commitments, or describe a buy to let as a home you will live in. That is mortgage fraud, and it is you who signs the declaration.
• Recommending a product without giving you an ESIS illustration.
• No written record of why the recommended product suits you. You are entitled to know the reasoning.
• Cash payments, personal bank transfers to an individual rather than the firm, or requests to pay through an unusual channel.

If a firm is unwilling to give you the ESIS or the fee in writing, that is not a personality quirk. Firms are required to disclose fees before you commit and to provide the illustration for a recommended product.

A large share of the mortgage traffic online belongs to comparison and lead generation businesses. You fill in a form, and your details are sold or passed to one or more brokers who then call you. Some of these operators are perfectly reputable and are simply an introduction service. Others sell the same enquiry to several firms, which is why some people find themselves fielding six calls in a day.

The distinction to hold onto is this. A lead generation site does not advise you and does not carry responsibility for the suitability of a mortgage recommendation. The regulated adviser at the end of the chain does. So it does not matter much how you were introduced. What matters is that you run the FCA Register check on whoever ends up advising you, and that you know their fee and their market access before you go further.

A directory that simply lists firms and lets you contact them yourself gives you more control, because you choose who to approach rather than having your details distributed.

A good adviser will start with a fact find covering income, outgoings, credit history, deposit source and future plans. They should explain their fee and their market access at that stage, not later. They should then research and recommend a product, give you the ESIS illustration, and be able to explain why that product beat the alternatives.

If something goes wrong, complain to the firm first. Firms normally have up to eight weeks to give a final response, after which you can take the complaint to the Financial Ombudsman Service. Knowing that route exists is part of why the FCA Register check at the start is worth the two minutes it takes.

If you would rather choose an adviser yourself than have your details passed around, the MortgageMatch directory lets you browse FCA-authorised brokers and approach the ones you like directly.
