Mortgage Brokers Explained: What They Do, Fees and How They Work

A mortgage broker, also called a mortgage adviser, helps you understand your borrowing options, compares mortgages available through their service and recommends a suitable option based on your circumstances.

They can also prepare and manage the application, communicate with the lender and help you deal with questions during underwriting.

You do not have to use a mortgage broker to get a mortgage. A broker cannot guarantee approval, and they will not always beat every deal available directly from a bank.

Their value is often in knowing which lenders are a realistic fit, comparing the full cost rather than one headline rate and helping you avoid preventable delays.

What is a mortgage broker?

A mortgage broker is an intermediary between you and a mortgage lender.

The broker does not lend you the money or set the lender’s interest rates. Instead, they assess your needs and circumstances, identify mortgages that may be suitable and explain why they are recommending a particular option.

In the UK, the terms mortgage broker and mortgage adviser are commonly used to mean the same thing.

For regulated residential mortgages, advice is a regulated activity. You should check the firm on the FCA Financial Services Register before sharing sensitive information or acting on a recommendation.

A broker’s job is not simply to find the lowest rate on a sourcing system. A suitable recommendation may also depend on:

  • How the lender assesses your income
  • The size and source of your deposit
  • Your credit history and existing commitments
  • The property type and condition
  • The mortgage term and repayment method
  • Product fees and incentives
  • Early repayment charges
  • Overpayment options
  • How your plans may change during the initial deal period

That is why the mortgage with the lowest advertised rate is not automatically the most suitable or lowest-cost option for you.

What does a mortgage broker actually do?

The exact service varies between firms, but a mortgage broker will usually:

  1. Learn about your plans. They will ask whether you are buying, moving, remortgaging or investing, as well as what you want the mortgage to achieve.
  2. Review your finances. This normally includes your income, spending, debts, deposit, credit history and expected future changes.
  3. Check your documents. A careful broker looks for gaps or inconsistencies before a lender’s underwriter sees them.
  4. Research lenders and products. They compare the options available through their service and consider both product features and lender criteria.
  5. Make and explain a recommendation. If advice is being given, they should explain why the mortgage suits your needs and discuss important drawbacks or restrictions.
  6. Prepare the application. They can help organise the evidence and present the case clearly to the lender.
  7. Manage the application. They may communicate with the lender, respond to underwriting questions and keep you updated through valuation and mortgage offer.

A broker is not your solicitor, surveyor or estate agent. They cannot control the property valuation, legal work, chain or lender’s final decision, but they can help keep the mortgage part of the transaction organised.

Mortgage broker, direct lender or comparison site?

These routes are not identical.

A comparison site can be useful for early research, a direct lender can discuss its own range, and a broker can compare lenders covered by their service and provide personalised advice.

Mortgage broker vs direct lender vs comparison site
What to compare Mortgage broker Direct lender Comparison site
Choice Compares lenders and products covered by the broker’s service. This may include intermediary-only options. Covers that bank or building society’s own range, including any relevant direct-only products. Displays selected advertised products. Availability and eligibility still need to be checked.
Personal advice Can make a tailored recommendation after assessing your circumstances. May offer advice on its own products or allow you to choose without advice. Usually provides information and filters rather than a personal recommendation.
Lender criteria Can compare how different lenders may treat your income, credit profile, deposit and property. You must meet that lender’s particular criteria. Important criteria may not be visible in the initial results.
Application support Often prepares, submits and follows the application through underwriting. You deal with the lender and provide the documents it requests. You normally leave the site to apply with a lender or connected broker.
Cost May charge a client fee, receive lender commission, or both. The arrangement should be explained upfront. No separate broker fee, although mortgage product and other transaction fees may apply. Usually no charge for searching, but product fees and any later advice fees may apply.
Often useful for People wanting advice, wider comparison or help with a difficult case and administration. Someone with a straightforward case who knows which lender and product they want. Early research and getting a broad sense of advertised rates and product types.

The right route depends on your circumstances and the service you want.

If you are specifically choosing between an adviser and applying to a bank yourself, read our full comparison: Should I use a mortgage broker or go direct to a lender?

How does the mortgage broker process work?

1. Initial conversation

The first conversation is used to understand what you need and whether the broker is likely to be able to help.

Ask what the service covers, how the broker is paid and whether the conversation creates any obligation.

At MBNM, this first chat is free. We use it to understand your requirements and establish whether we can help.

If we can, we discuss any fees with you before work moves forward. There are no hidden fees, and nothing proceeds until the fee has been agreed.

2. Fact-find and document review

If you choose to proceed, the adviser will gather more detail about your finances and plans.

You may be asked for:

  • Proof of identity and address
  • Recent payslips or evidence of other income
  • Bank statements
  • Accounts, tax calculations or contracts if you are self-employed
  • Details of loans, credit cards and other commitments
  • Evidence of your deposit and where it came from
  • Information about the property, if you have found one

Requirements vary by lender and case. Providing complete and accurate information at the start helps prevent avoidable questions later.

3. Affordability and lender research

The broker reviews how lenders may assess your borrowing.

This is more detailed than multiplying your salary by a fixed number. Lenders have different approaches to variable pay, overtime, bonuses, self-employed income, childcare, debts, dependants and other commitments.

The broker then researches products and criteria. A product can look attractive but still be the wrong option if the lender is unlikely to accept the income, deposit or property involved.

4. Recommendation and illustration

Where regulated advice is provided, the adviser should explain the recommendation and give you the relevant mortgage illustration.

Read it carefully. It sets out information including:

  • The interest rate
  • Monthly payments
  • Product and arrangement fees
  • The total amount repayable
  • Special features
  • Early repayment charges
  • What may happen if interest rates change

Ask questions if you do not understand why the product has been recommended or what would happen if your circumstances changed.

5. Agreement in Principle

An Agreement in Principle, sometimes called a Decision in Principle, gives an indication of what a lender may be prepared to lend based on initial information and checks.

It is not a mortgage offer and does not guarantee that the full application will be approved.

6. Full application, underwriting and valuation

Once you are ready, the application is submitted.

The lender checks the information and documents, assesses the property and may ask further questions.

The broker can help respond and keep track of outstanding items, but the lender makes the final decision.

7. Mortgage offer and completion

If the lender is satisfied, it issues a mortgage offer.

Your solicitor then deals with the legal work required before exchange and completion.

The broker may continue to coordinate with you and the lender, but the timescale also depends on the valuation, legal work and any property chain.

What does “whole of market” mean?

Not every mortgage broker has access to the same lenders.

  • A tied adviser is connected to one lender and advises on that lender’s range.
  • A panel-based broker works with a selected group of lenders.
  • A whole-of-market broker can consider a wide range of mortgages available through intermediaries.

Whole of market does not necessarily mean every mortgage sold in the UK.

Some products are only available directly from a lender, and some specialist products may sit outside a broker’s service.

Ask a broker to describe their range accurately and whether they will tell you when a direct-only option may be worth considering.

MBNM provides independent, whole-of-market mortgage advice and currently has access to more than 90 lenders.

The relevant options will still depend on your circumstances and the type of mortgage required.

How do mortgage brokers get paid?

Mortgage brokers may be paid in one or both of these ways:

  • A fee from the client. This might be a fixed amount, a percentage or a fee based on the type and difficulty of the work.
  • Commission from the lender. This is commonly called a procuration fee and is normally paid after a mortgage completes.

A broker described as “fee-free” to the client may still receive commission from the lender.

Receiving commission does not remove the requirement for suitable advice, but you should understand how the firm is paid and what you may have to pay.

Broker fees are separate from mortgage product fees and other buying or remortgaging costs.

When comparing options, look at the overall position, including:

  • Broker fees
  • Lender arrangement or product fees
  • Valuation and legal costs
  • Cashback or other incentives
  • Monthly payments during the initial deal period
  • Early repayment charges

Do not proceed based on a vague promise that costs will be explained later.

Ask what is payable, when it becomes payable, what the fee covers and what happens if the application does not complete.

Are mortgage brokers worth it?

A mortgage broker may be worth using when their knowledge, lender access and application support save you time, help you avoid an unsuitable application or give you access to an option that better fits your circumstances.

That can matter even when the broker recommends the same mortgage you saw online. Suitability checks, document preparation and application management are part of the service too.

However, using a broker is not compulsory and is not automatically the right answer for everyone.

Applying directly may suit you if your circumstances are straightforward, you already understand the lender and product you want, and you are comfortable managing the research and application yourself.

The honest answer is not “brokers are always worth it”.

A good broker is worth it when the value of the advice and support is greater than the cost and you understand the alternatives.

When can a mortgage broker be particularly useful?

You are a first-time buyer

The mortgage is only one part of buying a home, but it is often the part with the most unfamiliar terminology and evidence.

A broker can explain the stages, help you prepare and identify lenders whose criteria fit your deposit and circumstances.

Read more about first-time buyer mortgages.

You are self-employed or have complex income

Lenders do not all assess sole traders, company directors, contractors, bonuses, overtime or multiple incomes in the same way.

A broker can identify which approaches are more realistic before an application is submitted.

This does not guarantee approval, but it can reduce guesswork.

You have a small deposit or credit issues

The timing, amount and explanation of credit issues can affect lender choice.

A broker can discuss what the lender is likely to ask for and whether applying now is sensible.

Be wary of anyone who promises approval before properly reviewing your circumstances.

You are remortgaging

The right comparison may include a product transfer with your current lender as well as remortgaging elsewhere.

Fees, early repayment charges, property value and your future plans can all change the answer.

Learn how MBNM supports remortgage clients.

You are buying to let

Buy-to-let lending uses different affordability and property criteria from a standard residential mortgage.

Tax and legal structure can also matter, although mortgage advice is not tax advice.

See our buy-to-let mortgage service and obtain specialist tax advice where needed.

You do not have time to manage the application

Even a straightforward mortgage can involve documents, follow-ups and deadlines.

A broker can take on much of the mortgage administration, although you will still need to provide information promptly and remain involved in important decisions.

Common worries people have about mortgage brokers

“I found the same mortgage online. What am I paying a broker for?”

A broker’s value should not be judged only by whether a rate is exclusive.

Ask what checks they completed, why the lender fits your case, how the total cost compares and what support is included after submission.

If the adviser cannot explain the value clearly, you have useful information before committing.

“The estate agent booked me in with its broker. Do I have to use them?”

No.

You can listen to the recommendation, but you are not obliged to choose an estate agent’s in-house or recommended broker.

Compare their lender access, fees, experience and service with another regulated firm before deciding.

“Can I speak to more than one broker?”

You can compare firms before choosing.

Tell each adviser what has already been done and do not allow several firms to submit mortgage applications without coordination.

Duplicate applications can cause confusion and may result in additional credit searches or fees.

“Should I hide an old missed payment or debt?”

No.

Give accurate information about income, spending, credit commitments and previous issues.

Lenders verify information, and an unexplained difference can create a larger problem than the original issue.

A broker can only give useful guidance if they understand the full picture.

Mortgage broker myths and the reality

Myth 1: A broker can guarantee mortgage approval

Reality: Only the lender can approve the application.

A broker can assess fit, prepare the case and reduce avoidable mistakes, but cannot control underwriting or valuation.

Myth 2: The lowest rate is always the best mortgage

Reality: Product fees, incentives, early repayment charges, flexibility and the expected balance can change the overall cost.

Suitability matters as well as price.

Myth 3: Whole of market means every deal from every lender

Reality: A whole-of-market service covers a wide range of intermediary products, but direct-only deals and products outside the broker’s service can exist.

Myth 4: A fee-free broker is not paid

Reality: A fee-free broker may receive commission from the lender.

Ask for the payment and fee arrangements to be explained before proceeding.

Myth 5: There is one “easiest” mortgage lender

Reality: There is no universal easiest lender.

A lender that suits one applicant may decline another because income, credit history, deposit, affordability and property all matter.

Myth 6: A broker always saves money

Reality: A broker may find a lower-cost or better-fitting mortgage, but savings cannot be promised.

The service may also be useful because it saves time, manages difficult cases or helps avoid applying to an unsuitable lender.

An everyday example: when the product is not the real problem

Imagine a contractor who sees an attractive rate and receives an online Agreement in Principle.

They assume the full application will be routine.

During underwriting, the lender asks for evidence that does not fit how the contractor is paid, and the case stalls.

The lesson is not that contractors cannot get mortgages or that one particular lender is difficult.

It is that lenders interpret income differently.

A broker can review the contract, accounts or tax documents first, identify lenders whose criteria are more likely to fit and explain the evidence needed before submission.

This is an illustrative example, not a promise of approval. The right approach depends on the applicant, lender and property.

How to choose a mortgage broker

Before agreeing to proceed, ask:

  1. Are you listed on the FCA Register, or are you an Appointed Representative of a regulated firm?
  2. Are you whole of market, panel-based or tied to one lender?
  3. Do you have experience with circumstances like mine?
  4. How are you paid, and what will I pay in total?
  5. When does any fee become payable, and what happens if the mortgage does not complete?
  6. Will you consider or flag relevant direct-only deals?
  7. Who will manage my application after it is submitted?
  8. How and how often will I receive updates?

Frequently asked questions

Do I need a mortgage broker?

No. You can apply directly to a bank or building society.

A broker may be useful if you want help comparing lenders, checking criteria, choosing a suitable mortgage or managing the application.

What is the difference between a mortgage broker and a mortgage adviser?

In the UK, the terms are commonly used interchangeably.

Both usually describe a specialist who helps a customer find and arrange a mortgage and may provide a regulated recommendation.

Do mortgage brokers get better rates?

Some brokers can access intermediary-only products, while some lenders offer direct-only deals.

A broker may find a better-fitting or lower-cost option, but should not promise that they will always obtain a better rate.

How much does a mortgage broker cost?

It depends on the firm, mortgage and difficulty of the case.

A broker may charge a fixed fee, a percentage or no client fee, and may also receive commission from the lender.

Ask for the full arrangement in writing before agreeing to proceed.

How do mortgage brokers get paid?

They may receive a fee from you, commission from the lender, or both.

A broker should explain how they are paid and any amount you must pay before you commit.

When should I speak to a mortgage broker?

Ideally, speak to one before you submit a full application or commit to a property.

Early advice can help you understand likely affordability, prepare documents and identify potential issues.

Remortgage clients often start reviewing options before their current deal ends, but the right timing depends on the deal and any early repayment charge.

Can a mortgage broker improve my chances of approval?

A broker may help you approach lenders whose criteria better fit your circumstances and submit a stronger, more complete application.

They cannot guarantee approval because the lender makes the final decision and must also accept the property.

Is mortgage advice regulated in the UK?

Advice on regulated residential mortgages is a regulated activity.

Check the firm and its permissions on the FCA Financial Services Register.

If you are unhappy with regulated advice, complain to the firm first. If the matter is not resolved, you may be able to take it to the Financial Ombudsman Service.

Is a whole-of-market mortgage broker better?

A wider lender range can create more choice, but access alone does not prove that a broker is right for you.

Experience, clear fees, service quality and the ability to explain a recommendation also matter.

Can a mortgage broker help with bad credit?

They may be able to identify lenders that consider the type, age and cause of the credit issue.

Available options and pricing depend on the full circumstances, and no responsible broker should guarantee acceptance.
