Mortgage Broker vs Bank: Which Is Better?

The key difference between a broker and a bank

When you need a mortgage, you have two main routes: going directly to a bank or building society, or using an independent mortgage broker. The fundamental difference is choice. A bank can only offer its own mortgage products — typically a limited range of rates and terms. A mortgage broker, by contrast, has access to products from dozens or even hundreds of lenders, including specialist providers and exclusive deals not available directly to the public.

Around 80% of UK mortgages are now arranged through brokers, according to UK Finance data. This shift reflects the growing complexity of the mortgage market and the increasing value that professional advice provides in navigating it.

Advantages of using a mortgage broker

The primary benefits of using a broker include:

• Whole-of-market access: Brokers typically search across 50 to 100+ lenders, including banks, building societies, and specialist providers. This dramatically increases the chance of finding the best rate and terms for your circumstances
• Exclusive products: Many lenders offer mortgage products exclusively through brokers that are not available to direct applicants. These broker-only deals are often more competitively priced
• Expert advice: Brokers understand how different lenders assess income, treat self-employment, and handle complex situations. This expertise is invaluable if your circumstances are anything other than straightforward
• Time saving: Instead of researching and applying to multiple lenders yourself, the broker does the comparison work and handles the application process
• Credit file protection: A good broker knows which lenders are likely to approve your application, reducing the number of hard credit searches on your file

Advantages of going direct to a bank

There are situations where going directly to a bank makes sense:

• Existing customer deals: Some banks offer preferential rates to existing current account or savings customers that may not be available through brokers
• Simple straightforward cases: If you are employed with a regular salary, have a large deposit, and are buying a standard property, the cheapest product may be available directly
• Speed for existing customers: Banks sometimes fast-track applications from existing customers with established banking relationships
• No broker fees: While many brokers offer free advice (earning commission from the lender instead), some charge fees of £300 to £1,000 or more. Going direct eliminates this cost

When a broker is essential

Certain situations almost always benefit from using a mortgage broker rather than approaching a bank directly:

• Self-employed borrowers: Different lenders treat self-employed income very differently. A broker knows which lenders are most favourable for your specific business structure and income level
• Complex income: If your income includes bonuses, commission, overtime, rental income, or multiple sources, a broker can identify lenders that will maximise your borrowing capacity
• Poor credit history: Specialist lenders cater for people with adverse credit, but their products are almost exclusively available through brokers
• Unusual properties: Non-standard construction, ex-council properties, high-rise flats, and properties above commercial premises can be difficult to mortgage. Brokers know which lenders accept these property types
• Buy-to-let and portfolio landlords: The buy-to-let market has specialist lenders with complex criteria that brokers navigate daily

Understanding broker fees and costs

Mortgage brokers are paid in one of three ways: commission from the lender (no cost to you), a fee charged to you (typically £300–£1,000), or a combination of both. Many brokers operate on a fee-free basis, earning their income entirely from lender commission. This commission is built into the mortgage product and is the same whether you apply through a broker or direct — you are not paying extra by using a broker.

Fee-charging brokers argue that their fees enable them to recommend the very best product without being influenced by commission levels. In practice, all regulated brokers are required to recommend a suitable product regardless of how they are paid. The FCA mandates that advice must be in the client's best interest.

How to choose a mortgage broker

When selecting a broker, ensure they are authorised and regulated by the FCA (check the Financial Services Register), confirm whether they search the whole market or a limited panel of lenders, read reviews and testimonials from previous clients, ask about their experience with your specific circumstances, and clarify their fee structure upfront.

A good broker should take time to understand your situation, explain your options clearly, and never pressure you into a decision. If a broker seems more interested in pushing a specific product than understanding your needs, look elsewhere.
