What Does a Mortgage Broker Do? Slough Guide
A mortgage broker compares mortgage deals from different lenders, checks which ones you are likely to be accepted for, and handles the paperwork for you from your first chat right through to completion.
In short:
- A broker looks at your income and outgoings, then finds lenders that suit you
- They compare rates, fees, and terms across the market, not just one bank
- They fill in the application and deal with the lender on your behalf
- Most brokers are paid by the lender, not by you, though some charge a fee too
- They are regulated by the FCA, so there are clear rules on how they must treat you
If you are wondering whether a broker is even worth using, or what they actually do all day, this guide covers it properly.
Most people buying a home in the UK now use a broker rather than walking straight into their own bank. That is worth knowing before you start, since it shapes what “normal” looks like in this process.
A mortgage broker is not the same as a bank employee. A bank can only offer you its own products. A broker works across many lenders and is meant to find what suits you, not just what their employer sells.
Brokers in the UK must be authorised by the Financial Conduct Authority, or FCA. This means they have to follow rules about how they advise you and how clearly they explain fees. You can check any broker on the FCA register before you use them. You can check our listing here.
What does a mortgage broker actually do, step by step?
Here is what usually happens once you get in touch:
1. First conversation. You talk about your income, your outgoings, and what kind of property you want to buy.
2. Checking your finances. The broker looks at what you can realistically afford, not just what you would like to borrow.
3. Comparing lenders. They search the market for lenders likely to accept you, not just the ones with the lowest headline rate.
4. Recommending a mortgage. They explain why a particular deal suits your situation, including the rate, fees, and terms.
5. Handling the paperwork. They help gather your documents and fill in the application properly, so nothing gets missed.
6. Talking to the lender for you. If the lender asks a question or wants more information, your broker deals with it.
7. Seeing it through. They stay involved until your mortgage completes, including at the valuation and offer stage.
How much does a mortgage broker cost?
This varies. Some brokers charge no fee at all and are paid by the lender through a commission once your mortgage completes. Others charge a fixed fee, commonly a few hundred pounds, or a small percentage of the loan.
As an example of how this can look in practice, a fixed fee broker might charge a flat amount regardless of your mortgage size, while a percentage based broker might charge something like 0.3% to 1% of the loan amount, so the fee grows with how much you borrow. These are illustrative examples only, not fixed industry figures, since every broker sets their own pricing.
Always ask upfront how a broker is paid, and get it in writing before you go any further. A broker who is not clear about this straight away is a warning sign.
Is a mortgage broker actually worth it?
Here is the honest split.
Where a broker helps:
- You save time, since they do the comparing and chasing for you
- You get access to more lenders than you would find alone
- You get help understanding what you can genuinely afford
- You have someone dealing with problems if something goes wrong mid application
Where it might matter less:
- If your situation is very simple and you already know exactly which lender you want
- If cost is a bigger concern than convenience, and you are happy to do the research yourself
- Not every broker has access to every lender, so it is worth checking their reach before committing

For most first time buyers, and for anyone with a situation that is not completely straightforward, a broker tends to be worth it.
Where a broker matters most?
A broker’s value goes up the moment your situation is not the simplest case going. This includes:
- Self employed applicants, since lenders look at income differently and a broker knows which ones are comfortable with that
- Anyone with poor or limited credit history, since some lenders are far more flexible than others
- Buyers with a small deposit, since not every lender offers the same terms at higher loan to value
- Buy to let purchases, since these often need a different type of lender entirely
- First time buyers, simply because the whole process is unfamiliar and a second pair of eyes helps avoid mistakes
Should you use the estate agent’s recommended broker?
Not automatically, no. You are never required to use the broker an estate agent suggests, even if you are buying through them.
There is a real reason to be cautious here. If an estate agent’s in house broker sees your full financial position, the agent may get a clearer picture of your maximum budget, which could be used to push you or the seller toward a higher price. An agent telling you that your offer will be disadvantaged unless you use their broker is not allowed, this is known as conditional selling.
You are always free to choose your own broker.
Can you trust a broker who earns commission?
This is a fair question, and worth answering honestly rather than glossing over.
Yes, most brokers are paid a commission by the lender. This is standard, disclosed, and regulated. It does not mean a broker is free to push you toward a worse deal, since FCA rules require them to recommend what is suitable for you, not just what pays them the most.
A broker’s business also depends on referrals and reputation, so consistently steering people toward poor deals is not a sustainable way to run one.
How do you choose a good mortgage broker?
A few questions are worth asking before you commit to anyone:
- How many lenders do you work with?
- How are you paid, and what will it cost me?
- What is included in your service? Will you handle the paperwork and chase the lender for me?
- Have you dealt with cases similar to mine before?
- Are you on the FCA Financial Services Register?
Many advisers also hold a recognised qualification such as CeMAP, which is worth asking about too.
If you want to understand the difference between a broker who covers the whole market and one tied to a limited panel of lenders, we cover that properly in our separate guide on whole of market versus tied brokers.
What if something goes wrong?
If you are ever unhappy with the advice you have been given, put your complaint in writing to the broker or lender first. If it is not resolved within eight weeks, you can take it to the Financial Ombudsman Service.
