Whether a mortgage broker saves you money or just adds to the costs of an already expensive process comes down to your situation. For some people, that help is genuinely useful. For others, it can add less value.

A mortgage broker is an intermediary between you and lenders, regulated by the Financial Conduct Authority (FCA), who helps match your situation to mortgage products and lenders that may fit.

This guide walks through when a broker is worth using, when you probably don't need one, what brokers can and can't do, and what the costs can look like in practice.

Roughly 89% of UK mortgages are arranged via an adviser or broker, according to The Intermediary Mortgage Lenders Association (IMLA) in 2025.

Is a mortgage broker worth it?

Whether a mortgage broker is worth using depends on your circumstances. Many people find a broker particularly helpful where their income, credit history or borrowing needs are more complex, especially if your case isn't straightforward. They tend to add the most value if you're self-employed, have complex income, bad credit, are buying to let, remortgaging, or have been declined by a bank. If your situation is very simple and you've already found a competitive direct deal, a broker may add less.

What a mortgage broker actually does

A mortgage broker looks at your finances, works out which lenders are likely to consider your application, compares suitable deals, helps with the paperwork, and speaks to the lender through to completion. They are the middle person between you and the lender.

Whole-of-market brokers search a wide range of lenders, though some deals are only available directly or through selected brokers. That means broad access is useful, but no single source sees absolutely everything.

Most mortgage brokers hold or are working towards recognised qualifications, such as the Certificate in Mortgage Advice and Practice (CeMAP), issued by the London Institute of Banking & Finance (LIBF). Advisers in training can give advice if supervised within an FCA-authorised firm.

Broker vs adviser: Is there a difference?

In the UK, mortgage broker and mortgage adviser are used interchangeably. They generally mean the same job.

The more useful distinction is whether the person works with one lender, a limited panel, or a wide range of lenders. That tells you far more about the options you're likely to see than whatever title they use.

When using a broker is usually worth it

Using a broker is often worth it when your mortgage situation is less straightforward, or you want help managing the process.

• You're self-employed, or your income varies. Lenders assess self-employed income in different ways, and that can change what you're offered. A broker who understands self-employed mortgage criteria can help narrow down the lenders more likely to fit your case.
  
• You have bad credit or a thin credit file. Some lenders are stricter than others on missed payments, defaults, or limited borrowing history. If you are getting a mortgage with bad credit, a broker can help avoid lenders whose rules are unlikely to work for you.
  
• You're buying to let. BTL affordability works differently from standard residential borrowing. If you are looking at buy-to-let mortgages, a broker familiar with rental stress tests and landlord criteria can usually save time. Many buy-to-let mortgages are not regulated by the Financial Conduct Authority
  
• Your bank has declined you or offered a weak deal. One lender saying no doesn't automatically mean the next one will. A broker can help place your case with lenders whose criteria may suit you better.
  
• You're remortgaging and want to compare properly. A product transfer with your current lender may be fine, but it may not be the strongest option. A broker can compare that against other available deals when you are remortgaging. Before switching mortgage products or lenders, check whether any early repayment charges or fees apply, as these could affect the overall cost.
  
• You're short on time. Mortgage paperwork, chasing documents, and back-and-forth with lenders can easily turn into a part-time job for a few weeks. If you want someone else to organise that process, using a broker can make things easier.

When you probably don't need a broker

You may not need a broker if your circumstances are simple and you've already found a competitive deal yourself.

A simple product transfer with your current lender is one example. If your fixed deal is ending and your lender's new rate already looks competitive, you can often accept it online without a full new affordability check or credit check.

The gap can also be smaller when the case itself is straightforward. Think salaried employment, stable income, clean credit, a standard property, a decent deposit, and enough time to compare a few lenders yourself.

A direct offer from your bank that already compares well against comparison sites or MoneySavingExpert may also reduce the value a broker adds, though a second opinion can still be useful.

And for confident researchers who don't mind forms, lender criteria, and comparing rates themselves, going direct can be completely reasonable.

Looking at the pros and cons of using a mortgage broker side by side can make the trade-offs easier to judge.

Habito is authorised and regulated by the Financial Conduct Authority (FRN 714187).

What a mortgage broker can't do

A broker can help a lot, but there are some things they simply can't do.

• No broker can guarantee the cheapest rate. Certain deals are only available through brokers, while others can only be accessed directly. A broker can widen your search, but they can't promise the absolute cheapest deal in every case.
• Your credit score and affordability still matter too. A broker can steer you toward lenders whose rules better suit your situation, but they can't make a lender ignore failed affordability checks or credit issues.
• Slow underwriting is outside a broker's control. They can reduce delays caused by missing documents or poor admin, but they can't make an already slow lender work quickly.

A good broker can make the process smoother and help you avoid dead ends. 

What does it actually cost? Doing the maths

Mortgage brokers are usually paid either through lender commission, a fee charged to you, or a mix of both.

Fee-free brokers are common, and Habito is one of them. If a broker is described as fee-free, that usually means they receive a procuration fee, commission paid by the lender. It is often around 0.35% of the loan, though some lenders pay more depending on the deal and broker.

Other brokers charge a flat fee, a percentage of the loan, or a mix of fee and commission. For a deeper breakdown, you can read about how mortgage brokers charge.

A simple example: Say you're borrowing £200,000 over 25 years. A paid broker charges £500. If they find a rate that is 0.15 percentage points lower than the one you would have taken yourself, that could mean roughly £25 a month lower repayments early on, or about £600 over a 2-year fixed term.

In some cases, the savings can outweigh the fee. In others, the difference may be much smaller, especially if you had found a similar deal yourself.

These figures are illustrative examples only and are not guaranteed outcomes. The amount you may save depends on factors including the rate available to you, fees, loan size, loan term, and lender criteria.

How to spot a good mortgage broker

If you're going to use a broker, a few quick checks can make it easier to spot a good broker.

• Check the FCA Register. Look up the firm on the FCA Register. Make sure you know who is advising you and that the firm is authorised.
  
• Ask about the lender range. Find out whether they work with one lender, a panel, or a wide range.
  
• Ask how they are paid. A broker should explain this clearly in the Initial Disclosure Document. You want to know whether they charge you, the lender, or both.
  
• Check their track record. Reviews, recommendations, and how clearly they answer questions all matter. 

For a fuller checklist, see how to find a mortgage broker you can trust and read these questions to ask a mortgage broker.

Good brokers are straightforward about their fees, easy to verify on the FCA Register, and clear about what they can and can't do.

Should you use the broker your estate agent recommends?

Probably not automatically. Estate agents often earn referral fees when they send buyers to an in-house or preferred broker, so the recommendation isn't fully neutral.

There's another issue, too. If you use the estate agent's broker, you may reveal details about your upper budget to the seller's side of the transaction. That doesn't automatically make the recommendation a bad one, but it does mean the incentives are worth being aware of.

Estate agents can recommend a broker. They cannot insist that you use one. That pressure is often described as conditional selling. If you want the full background, read more about the estate agent's recommended broker.

Frequently asked questions

Quick answers to the questions people most often ask about mortgage brokers.

Is it better to go to the bank or a broker?

It depends on your circumstances. A bank will only show you its own products, so you see one set of options. A broker can compare across many lenders, which is often more useful if your case is complex or you've already been declined. For simple cases with a strong bank offer, the difference may be smaller.

What are the disadvantages of using a mortgage broker?

Some brokers charge a fee, not every broker searches the same range of lenders, and quality can vary. A broker also can't access every deal because some are direct-only. In some cases, if your situation is very simple, the difference a broker makes may be smaller.

Do mortgage brokers get better rates?

Sometimes, but not always. Some brokers can access deals you wouldn't find going direct, and they may know which lenders are more likely to accept your case. But some deals are direct-only, so a broker doesn't automatically have better rates in every situation.

Are mortgage brokers free?

Some are free to the customer because they are paid by the lender's commission. Others charge a flat fee, typically around £300 to £500, or a percentage of the loan up to around 1%. The mix varies, so it's worth checking how brokers are paid before you choose one.

Do I need a mortgage broker to remortgage?

No, you don't. You can accept a product transfer with your current lender or apply directly elsewhere yourself. A broker can still be useful because they can compare your current lender's offer against the wider market before you decide.

Should I use a mortgage broker as a first-time buyer?

For many first-time buyers, yes, it often makes sense. The process is new, the paperwork can feel complex, and lender rules around deposit size, income, and employment history can vary. A broker can also help you get a mortgage in principle and compare mortgage deals before you commit.

Talk to a Habito mortgage adviser

So, is a mortgage broker worth it? Often yes, but not always. If your case is complex, time is tight, or you want to compare more lenders, a broker can make a real difference. If your situation is straightforward and you already have a strong direct offer, the case for using one is weaker. It really comes down to your circumstances, not a blanket rule.

When you're ready to start

If you'd rather not handle the comparison alone, a Habito adviser can help. Habito advisers search across a wide range of lenders, the service is fee-free, and you can start online, get a mortgage in principle, or chat with an adviser, depending on how hands-on you want to be.
