Why Use a Mortgage Broker
Updated 12 April 2026
A mortgage broker acts as an intermediary between you and the lenders, searching the market on your behalf to find mortgage products that match your circumstances. With the UK mortgage market now comprising over 200 active lenders — each with different criteria, rates, fees and product structures — a broker’s role is to navigate that complexity so you do not have to. This guide explains what a broker does, the difference between whole-of-market and restricted advice, the situations where a broker adds the most value, how fees work, and what to expect from the process.
Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.

What a Mortgage Broker Does
A mortgage broker assesses your financial situation, identifies suitable lenders and products, and manages the application process from initial enquiry through to completion. This includes gathering your documentation, submitting the application to the chosen lender, liaising with the lender’s underwriters if queries arise, and coordinating with your solicitor on timing.
The Intermediary Mortgage Lenders Association (IMLA) estimates that brokers now account for approximately 89% of all mortgage lending in the UK, with that figure forecast to exceed 90% by 2026. The scale of the intermediary channel reflects the practical reality that most borrowers find it difficult to compare products across dozens of lenders on their own, particularly when criteria vary widely and can change at short notice.
Whole of Market vs Going Direct
The term whole of market means the broker can access products from across the multiple lenders in the market, rather than being restricted to a single lender or a limited panel. This is the standard Mortgage One operates on. By contrast, a bank or building society adviser can only recommend that institution’s own products, and a restricted or tied broker is limited to a defined panel of lenders.
The practical difference is significant. Going direct to your bank means you see only what that bank offers. If another lender has a more competitive rate, more favourable criteria for your income type, or a product structure that suits your situation better, you would not know about it. A whole-of-market broker can compare products across the market and identify the lender whose criteria and pricing are the strongest fit for your specific circumstances.
Some mortgage products are also available only through intermediaries — they cannot be accessed by applying directly to the lender. These intermediary-only products are common among specialist lenders and can sometimes offer more competitive terms than the lender’s direct range.
When a Broker Adds the Most Value
A broker can help any borrower, but the value is greatest when your situation involves any complexity. The following are examples of cases where broker expertise makes a material difference to the outcome.
• First-time buyers. Navigating the mortgage market for the first time is daunting. A broker explains the process, identifies suitable products and manages the application. A first-time buyer mortgage requires careful matching of deposit, income and lender criteria.
• Self-employed applicants. Lenders vary widely in how they assess self-employed income. Some require three years of accounts, others accept one year. A self-employed mortgage often depends on finding the lender whose criteria best fit your trading history and income structure.
• Adverse credit. Specialist lenders assess bad credit mortgages on a case-by-case basis, but applying to the wrong lender wastes time and adds hard searches to your credit file. A broker identifies which lenders are most likely to approve your case.
• Remortgaging. When your deal ends, staying with your current lender on a product transfer may not be the most competitive option. A broker can compare your existing lender’s retention deal against the wider market. Exploring your remortgaging options through a broker ensures you see the full picture.
• Buy-to-let and portfolio landlords. Lender criteria for buy-to-let mortgages differ significantly from residential lending, and portfolio landlord rules add further complexity. A broker understands the rental coverage calculations and stress tests each lender applies.
• Expats and overseas income. Borrowers earning in a foreign currency or living abroad face a restricted lender market. A broker with experience in expat mortgages knows which lenders accept overseas income and how currency risk is assessed.

How Mortgage Brokers Are Paid
Mortgage brokers are typically paid in one of two ways: a procuration fee from the lender, a fee charged to the client, or a combination of both. The procuration fee is paid by the lender to the broker for introducing the business — this does not come out of the borrower’s pocket and does not affect the interest rate offered.
Some brokers also charge a client fee, which can be a fixed amount or a percentage of the loan. Fee structures should be disclosed clearly before any work begins. Mortgage One offers a free initial consultation and will explain any applicable fees upfront before you commit to proceeding.
It is worth noting that using a broker does not necessarily cost more than going direct. The products available through a broker are typically priced the same as going direct to the lender, and in some cases intermediary-only products may offer more competitive terms. The broker’s value lies in matching you with the right lender and product, not in adding cost.
What to Expect from the Process
Working with Mortgage One follows a straightforward process. It starts with an initial conversation — typically by phone or video call — to understand your circumstances, income, deposit position and what you are looking to achieve. From there, Mortgage One searches the market, identifies suitable lenders and products, and presents recommendations with a clear explanation of the options.
Once you choose a product, Mortgage One handles the full mortgage application on your behalf — completing the paperwork, submitting to the lender, chasing updates and coordinating with your solicitor. You receive regular updates throughout, and Mortgage One is available to answer questions at any stage.
The process does not end at completion. Mortgage One monitors your deal and will contact you ahead of your current product expiring to discuss remortgage options, ensuring you do not default onto an expensive standard variable rate without considering the alternatives.

FAQs
1. Is a mortgage broker the same as a mortgage adviser?
In practice, the terms are often used interchangeably. A mortgage broker or adviser is a professionally qualified individual who searches the market on your behalf and recommends products suited to your circumstances. Brokers must hold a relevant qualification such as CeMAP.
2. Does using a broker guarantee I will get a mortgage?
No. A broker cannot guarantee approval because every lender has its own underwriting criteria and the final decision rests with the lender. However, a broker’s knowledge of lender criteria means applications are directed to lenders where there is a realistic prospect of approval, reducing the risk of unnecessary declines.
3. Will a broker find me a cheaper rate than going direct?
Not necessarily in every case, but a whole-of-market broker can compare products across the whole of market, including intermediary-only deals that are not available direct. This means a broker can often identify more competitive options than a single lender’s range, though there is no guarantee of a lower rate.
4. How much does a mortgage broker charge?
Fee structures vary by broker. Some charge no client fee and are paid entirely by a procuration fee from the lender. Others charge a fixed fee or a percentage of the loan. Mortgage One offers a free initial consultation and will explain any applicable fees before you commit.
5. Can I use a broker if I am self-employed or have bad credit?
Yes, and these are precisely the situations where a broker adds the most value. Lender criteria for self-employed income and adverse credit vary widely, and a broker knows which lenders are most likely to accept your application based on your specific circumstances.
6. Do I have to use a broker in person?
No. Mortgage One works with clients across the UK by phone and video call. There is no need to visit an office. The initial consultation, document submission and ongoing communication can all be handled remotely.
7. What does whole of market mean?
Whole of market means the broker can access products from across multiple lenders in the market, rather than being limited to a single lender or a restricted panel. This gives you the widest range of options when looking for a mortgage.
