Questions to Ask a Mortgage Broker

A good broker checklist covers three things. Who they are, how they are paid, and whether their recommendation genuinely suits your situation.

In short, before you commit to a broker, it is worth asking about:

• Their regulation, qualifications, and how many lenders they cover
• How they charge, and whether that affects the advice you receive
• What documents, timescales, and deposit you should expect
• Why the specific mortgage they recommend actually suits you, not just that it exists

If you want the full list of questions to ask a mortgage broker, along with why each one matters, this guide covers it properly.

Asking the right questions early protects you from ending up with a mortgage that does not really fit your circumstances, or a fee you did not fully understand until later. A mortgage broker and a mortgage adviser mean the same thing in the UK, so do not let the different wording confuse you. Some brokers work across the whole market, while others are tied to a smaller panel of lenders, and we cover that distinction properly in our separate guide on whole of market versus tied brokers.

Mortgage brokers in the UK must be regulated by the Financial Conduct Authority, known as the FCA, and must hold a recognised qualification such as the Certificate in Mortgage Advice and Practice, usually shortened to CeMAP. These standards exist to protect you, so it is always worth checking them for yourself rather than taking them on trust.

Questions about the broker themselves

Before you get into the detail of your own finances, it is worth understanding who you are actually talking to.

1. Are you regulated?

All UK mortgage brokers must be authorised and regulated by the Financial Conduct Authority to give mortgage advice. This regulation means they are required to follow set standards on how they advise you and disclose their fees. You can check any broker’s status yourself on the FCA Financial Services Register before agreeing to anything. Cubic Financial Services is regulated in this way, and we would encourage you to check us on the register too. Regulatory status can be checked at any time, but it is worth confirming it again if you have not spoken to a broker in some time.

2. What qualifications do you hold?

Mortgage brokers in the UK must hold a recognised qualification, most commonly the Certificate in Mortgage Advice and Practice, known as CeMAP. This qualification confirms they have met an industry-recognised standard of technical knowledge before giving advice. It sits alongside FCA regulation rather than replacing it, since one covers competence and the other covers conduct. Our advisers at Cubic Financial Services hold recognised qualifications for this reason. Individual brokers may hold additional or different qualifications, so it is fair to ask what theirs specifically covers.

3. Do you have professional indemnity insurance?

Professional indemnity insurance protects you financially if a broker’s advice turns out to be negligent or incorrect. It works alongside, rather than instead of, the FCA’s own complaints and redress process. Most regulated firms are required to hold this cover as a condition of their authorisation. Cubic Financial Services holds professional indemnity insurance as part of how we operate. Cover levels and terms can vary between firms, so it is reasonable to ask for specifics if this matters to you.

4. How many lenders do you work with?

The number of lenders a broker works with directly affects how wide a search they can carry out on your behalf. A broker tied to one lender can only offer that lender’s products, while a whole of market broker can compare far more widely.

5. How can I contact you, and how quickly will you reply?

Most brokers can be contacted by phone, email, or in person, depending on how they operate. Response times vary, and this matters more during time sensitive stages such as exchange of contracts.

Questions about how a broker is paid

6. How do you charge for your service?

Mortgage brokers are typically paid through a commission from the lender, a fee charged to you, or a combination of both. This should be explained to you clearly and in writing before any work begins.

7. Does how you are paid affect the advice you give me?

It should not. FCA rules require a broker to recommend a mortgage that is suitable for your circumstances, regardless of how that broker is paid. We cover this topic properly, including typical fee ranges and when fees are usually due, in our guide on how mortgage brokers get paid.

Questions about the process ahead of you

8. What documents will I need?

Most mortgage applications require proof of identity, proof of address, income evidence, and details of your deposit. Self employed applicants are usually asked for two to three years of accounts or tax calculations instead of payslips.

9. How long will the whole process take?

A mortgage application through a broker typically takes two to four weeks from submission to a formal offer, though the full property purchase usually takes several months. Our guide on how long a mortgage application takes through a broker breaks this down stage by stage.

10. How much deposit will I need?

Most UK lenders ask for a minimum deposit of 5% of the property price, though many buyers save more to access better rates. Our guide on how much deposit you need for a mortgage covers this in full, including how deposit size affects your options.

11. How much could I borrow?

Most lenders will consider lending somewhere around four to four and a half times your annual income, though this is only a general pattern. The exact figure depends on your income, outgoings, credit history, and the specific lender’s own criteria.

Questions about the mortgage they actually recommend

This is the stage many people skip, and it is arguably the most important one.

12. What type of mortgage are you recommending, and why?

A repayment mortgage and an interest-only mortgage work in fundamentally different ways, and a fixed, tracker, or discounted rate behaves differently over time too. A good broker should explain which type suits your circumstances and why, not simply present one option.

13. What happens once the initial deal period ends?

Most mortgage deals run for an initial period, often two to five years, after which many lenders move you onto their standard variable rate, known as the SVR. The SVR is usually higher than your initial rate, so many buyers choose to remortgage before this happens.

14. Are there any restrictions, such as early repayment charges or portability?

Early repayment charges, sometimes shortened to ERCs, can apply if you repay or leave your mortgage before the deal period ends. Portability refers to whether you could take your existing mortgage with you if you move house again in future.

15. Can I have a full breakdown of all the costs involved?

The total cost of a mortgage usually includes any broker fee, the lender’s arrangement fee, and a valuation fee, not just the headline interest rate. Seeing these together in one place helps you compare deals fairly rather than focusing on rate alone.

16. Do you earn anything from other products you recommend, like insurance?

Some brokers also earn commission from insurance products such as buildings cover or life insurance, separately from any mortgage related payment. You are never required to buy these through your broker, and you are free to compare them elsewhere.

17. Why is this mortgage the best fit for me?

A good broker should be able to explain clearly, in plain language, why a specific mortgage suits your circumstances rather than simply presenting it as the option available. This answer should reference your actual situation, such as your income, plans, and attitude to risk, not generic product features.
