A good broker should do more than “find rates”. They should:
Ask if they are whole-of-market today. That means access to most lenders available to brokers. Some lenders keep a few deals for direct applications only. A good broker will still benchmark those for you, explain the gap, and advise whether it is worth going direct. You should not have to guess.
Tip: Ask the broker to show a simple comparison that includes any known direct-only options, so you can choose with full information.
"A good broker doesn’t just find you a rate, they make sure the deal actually works for your life, not just your spreadsheet." — Will Sharman
Always ask, in writing, how they get paid and when you pay. Typical options are a broker fee, a lender commission, or both. Avoid large upfront fees before you have a formal mortgage offer.
Be cautious of estate agent pressure to use their in-house broker. That creates a conflict of interest and can limit your options. We explain the dynamics here:
Check the firm is authorised by the Financial Conduct Authority and that your adviser holds a recognised qualification such as CeMAP. Ask how they protect your personal data, who sees your bank statements, and how long they keep them. Good process here is a sign they will handle the rest of your case properly.
Different cases need different experience. First-time buyer, home mover, remortgage, buy to let, contractor, complex income. Ask the broker for two short case examples similar to yours and what made those applications succeed.

Agree how you will communicate and how often. Weekly updates keep momentum. Ask for a one-page timeline that covers:
Smart questions
Red flags
Ask each broker to give you, in writing:
Do I really need a mortgage broker, or can I go straight to a lender?
You can go direct, but a good broker compares many lenders, checks your documents up front, and steers you to a lender that is likely to say yes. That saves time, stress, and often money.
What does “whole of market” actually mean?
It means the broker can access most lenders that work with brokers. Some lenders keep a few deals for direct customers only. A good broker will still benchmark those so you can make a fair choice.
How do brokers get paid?
Usually by a commission from the lender, a fee from you, or both. Ask for the fee in writing, what it covers, and when it is due. Be wary of big fees before there is a formal offer.
Are estate agent recommended brokers worth using?
They can be, but there is a conflict of interest. You are not obliged to use them. Choose the broker that offers the widest choice, clear fees, and proper document checks.
How do I check a broker is legit?
Confirm the firm is authorised by the Financial Conduct Authority and that the adviser holds a recognised qualification such as CeMAP. Ask how they protect your data.
What questions should I ask before I choose?
Are you whole of market. How do you get paid. What will this cost in total including product fees. Which lenders fit my case and why. How often will you update me and who chases the lender and solicitor.
Can I speak to more than one broker?
Yes. Compare two or three. Ask each for a lender short list with reasons, a total cost illustration, and their update plan. Pick the one who explains the why, not just the rate.
Will a broker improve my chances of approval?
Often yes. They match your income, credit profile, and property type to lenders that will accept them. They also catch problems in your documents before you apply.
What documents will a broker need?
ID, proof of address, payslips or accounts, bank statements, details of your deposit and any gift, plus information about the property. Good brokers check these before giving you an AIP.
What are red flags when choosing a broker?
Pressure to use their in-house solicitor or insurance, vague answers about fees, no document checks before giving you an AIP, and slow or unclear communication.
How fast should I expect updates?
Weekly updates work well. You should know what happened this week, what is due next, and who is doing it.
Can I switch brokers if I am not happy?
Yes, unless you have signed a contract that binds you to a fee. If you switch, tell the new broker exactly what has been done so far and share your documents securely.
"Anyone can get an Agreement in Principle online, but a real broker checks your facts, not just your form." — Will Sharman
