What is a mortgage broker, and what do they do?

Mortgage brokers or advisers are financial intermediaries who help clients secure the right mortgage for their needs.

They work with various lenders, including some that may not be accessible directly to the public.

Your mortgage is one of your largest monthly outgoings. Just a small difference in your interest rate could save you thousands over the years.

Although there are plenty of deals around, using a mortgage broker can often give you access to cheap deals that aren’t available directly. It’s especially worthwhile if you have complex financial circumstances like a low credit rating or being self-employed. They’ll be able to help you find a deal that’s right for you.

Mortgage brokers are qualified experts, so when you want to buy a property, they will quiz you on your financial situation, intended property purchase, and the type of mortgage you need.

They will use this information to find the right deal for your circumstances.

Mortgage brokers can also give you expert guidance throughout the application process

Here’s a summary of how a mortgage broker could help.

What is a bank’s role in mortgage lending?

Banks play a more straightforward role in mortgage lending by offering their own range of mortgage products directly to their customers.

When comparing a mortgage broker and a bank, banks are limited to their internal portfolio, which could restrict the options available. 

However, there are some advantages to using a bank, including:

  • Streamlined communication for customers who already have accounts with the bank.

  • Potentially faster processing times for applications due to already-established relationships.

While banks offer less variety, their familiarity with existing customers can simplify the process for those who prefer a direct approach.

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

Working with a broker instead of a bank differs in several ways.

Here is a summary of the main differences.

DifferencesMortgage brokersBanks
Time to process applicationsOften handle most of the legwork, speeding up the process by ensuring all your documentation is accurate and completeApplying online may be fast, but if you’re sitting down with an in-house broker this can take longer. They have more responsibilities and may be slower in processing your application
Range of productsCan access products from multiple lenders, including niche providers unavailable to the publicOnly offer their own products, which can reduce variety but simplify decision-making
PersonalisationCan offer tailored advice and solutions based on your individual needs and circumstancesFocus on matching clients with their own products, which may not be ideal for everyone or the most competitive
CostsSome charge hourly fees or a percentage of the loan value for their services. Others are fee-free, but they earn a commission. However, brokers can often secure lower rates that offset their feesDon’t usually charge fees for mortgage advice, but may offer less competitive rates
Application supportProvide hands-on assistance with paperwork and the overall application process, and ensure you have the correct documentationMay offer less comprehensive support, often requiring customers to handle much of the process themselves

When you’re weighing up fees, it’s important to remember that broker fees can be added to the mortgage, but remember you will pay interest on both your mortgage and broker fees until the final amount is paid.

Is it best to use a mortgage broker or a bank?

Choosing between a mortgage broker and a bank depends on your circumstances.

You should consider using a broker if you’re keen to access multiple lenders, need tailored advice, or have a complex financial situation (such as an irregular income or poor credit).

A bank may be a better option if you prefer a more straightforward process, already have a strong relationship with your bank, or are comfortable comparing mortgage products independently. 

A first-time buyer with a low deposit may benefit from a broker’s expertise and access to niche products.

In contrast, an existing bank customer refinancing a mortgage may find their bank’s streamlined process more convenient.

When should you consider a mortgage broker?

A mortgage broker may be a better choice if:

  • You’re self-employed or have an irregular income.

  • If you want access to deals that only a broker can get for you.

  • If you want to access more competitive deals or find lenders with less strict criteria.

  • Your credit history or credit score is poor.

  • If you’re looking for additional products such as buildings or life insurance, a broker can help you find the right policy for your circumstances. 

When should you consider using a bank?

A bank may be more suitable for you if:

  • You have a long-standing relationship with your bank and are happy with its service.

  • You're confident in making an independent comparison of mortgage products against the bank’s own range.

  • The bank’s deal meets your needs, and your focus isn’t on finding the most competitive rate, as this may not be available via your bank.

  • Your circumstances aren’t complex, and you don’t need expert advice. 

How to decide between a mortgage broker and a bank

To make the best choice between using a mortgage broker and a bank:

  • Compare mortgage deals from both a mortgage broker and your bank.

  • Schedule a free consultation with a broker to see what they can offer you.

  • Consider the complexity of your financial situation and long-term plans.

Consulting a qualified mortgage broker is worthwhile, as they should give you independent advice, which you may not find with a bank offering only their mortgage products.
