A mortgage broker searches across multiple lenders, while your bank can only offer its own mortgage products. A broker can be particularly useful for complex applications, while a bank may be enough for straightforward cases and access to direct-only deals.

You have two main routes, and neither is right for everyone. The choice often comes down to your income type, credit history, and how much of the mortgage search you want to handle yourself.

Habito is a mortgage broker. If you'd like to learn more about what a mortgage broker does, we've covered that separately. 

In this guide, we've aimed to give a balanced view of both routes so you can decide which one makes the most sense for you.

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

What a mortgage broker does (and what your bank does)

A mortgage broker assesses your finances and searches across lenders to find a product that's suitable for your circumstances. There are three main types of mortgage professionals:

• Bank or building society advisers work directly for a specific institution. They know their own products well, but they're limited to what their employer offers.
• Tied or panel brokers operate independently of a single bank but only search a restricted, pre-selected list of lenders. Brokers are usually paid a commission by the lender when a mortgage completes. This is known as a procuration fee.
• Whole-of-market brokers search across a wide range of lenders to find a product that matches your situation. Some deals are only available directly or through selected brokers, so no single source covers everything.

If you're using a broker, ask how many lenders they search and whether any lenders or products are excluded from their panel.

When a broker can help more than your bank

Brokers make the biggest difference when something about your application is out of the ordinary. But if you have clean financials, a standard property, and a straightforward income, a bank can handle that without any help. That changes when your circumstances become more complex.

Complex income streams

If your income doesn't come from a single employer and a regular monthly salary, some banks can struggle to assess it. Self-employed mortgage options, contract workers, freelancers, and anyone with multiple income streams often run into this complication. 

Credit history issues

Missed payments, defaults, or County Court Judgments (CCJs) on your credit file make applying directly to a mainstream bank risky. Apply to the wrong lender and you end up with a hard search on your file. And if you get declined, that mark sits on your record when the next lender checks. 

Experienced brokers may be familiar with lenders whose criteria are better suited to non-standard income and more complex circumstances., and can often identify which lenders may be a better fit before you apply. That can reduce the risk of wasted applications and unnecessary hard credit searches.

When you receive regulated mortgage advice, the adviser is responsible for recommending a suitable product based on your circumstances. If something later goes wrong, you may also have access to the Financial Ombudsman Service.

First-time buyer uncertainty

First-time buyers rarely have an existing lender relationship, and the paperwork alone can feel like a lot to sort out. Brokers manage the communication with the lender and keep things moving, so you're not left chasing updates.

The same can apply if you're buying with a smaller deposit, as lenders assess higher loan-to-value mortgages differently.

Unusual property types

High-rise flats, ex-local-authority properties, new-builds, and non-standard construction (a thatched roof or timber frame) can sit outside some lenders' standard criteria. Brokers know which lenders are set up for these and won't waste your time with the ones that aren't.

Time-poor applicants

Searching across lenders, filling in applications, and chasing underwriters takes time most people don't have. A broker handles the search and the paperwork and deals with the lender's team directly.

When going directly to your bank makes sense

Going direct isn't a compromise. For some applications, it's the most efficient route.

• Simple, straightforward applications: Clean financials, a standard property, and a long-term permanent contract? A high-street bank is well set up for that. You don't necessarily need a broker.
• Existing relationship discounts: Some banks offer perks to existing account holders, such as reduced arrangement fees, rate discounts, or cashback that aren't available through a broker. However, an existing banking relationship doesn't automatically mean the mortgage will be the most competitive option.
• Direct-only deals: Some products are only available to customers who apply directly. They won't appear on any broker's sourcing system. 
• Product transfers at remortgage: If your fixed-rate deal is ending and your current lender has a competitive new rate, a product transfer is straightforward to execute. No new legal work and no new valuation. If the rate stacks up, going direct is the obvious call.

Do mortgage brokers get better rates than banks?

Not always. Brokers can access exclusive intermediary-only deals from certain lenders, but banks also offer direct-only rates that brokers cannot access. The better rate depends on your circumstances, the loan-to-value ratio, and what's available when you apply.

Brokers don't automatically unlock cheaper rates. They have access to products that aren't available to direct applicants, but banks also offer products that can only be accessed by applying directly. You won't know which option is cheaper until you've looked at both.

When you use a broker, they earn a procuration fee from the lender (a commission paid by the lender, often referred to as a procuration fee. The amount varies between lenders and products.). This covers the admin work the broker does on the lender's behalf. This commission doesn't usually affect the rate you're offered. 

When comparing options, look at the total cost across the fixed term, including the rate and any fees, rather than focusing only on the headline rate.

Can a broker help you borrow more?

Every bank uses a slightly different model to calculate how much you can borrow. Different lenders use different affordability models. Some may lend more than others depending on factors such as your income, profession, deposit size, and overall financial circumstances.

A whole-of-market broker works with dozens of lenders and understands how they assess affordability. If maximising what you can borrow matters for your purchase, a broker can point you toward lenders whose affordability criteria may be a better fit for you.

What about direct-only mortgage deals?

Some high-street lenders offer products only to customers who apply directly. These won't appear on any broker's sourcing system.

When someone applies directly, the bank doesn't pay a procuration fee to a broker. That saving sometimes gets passed on as a slightly lower rate or reduced product fee. How mortgage broker fees work explains this in more detail.

To make sure you're seeing everything available, check the major lenders' websites directly. Some lenders may offer mortgage products that are only available when applying directly. Check lender websites for the latest availability and eligibility criteria.. Compare what you find against what your broker presents.

Mortgage broker vs going to your bank: Comparison table

Here's how the two scenarios compare:

These figures are illustrative examples only and are not guaranteed borrowing amounts. The amount you may be able to borrow depends on factors including your income, regular spending, credit history, deposit size, and lender affordability checks.

The table is a starting point. In practice, the choice usually comes down to income complexity, credit history, and whether you want full market access or just your current lender's range.

Do you need a broker to remortgage?

If your current lender's rate is competitive and nothing about your finances has changed, staying put is usually the right move. It's fast, there's no new legal work, and you already have a head start by knowing exactly how your current deal compares with the new one. A broker may not add much in that scenario.

If you want to switch lenders, borrow more for home improvements, or your income has changed since you took out the original loan, a broker can be helpful. The remortgaging guide covers the full process.

The same applies if you're dealing with early repayment charges, porting an existing mortgage, or negative equity.

Frequently asked questions

Some of the most common questions about choosing between a mortgage broker and a bank:

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

You can't know without checking both. A fee-free broker costs you nothing upfront and may access rates you can't find directly. But banks sometimes have direct-only deals that aren't available through any broker. The only reliable approach is to get a broker recommendation and then check your bank's direct offer against it. Most people only do one or the other, which means they miss half the picture. Look at the total cost across the fixed term, not just the headline rate. Arrangement fees and product fees are part of the calculation.

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

The terms are often used interchangeably, but the distinction matters. A mortgage adviser who works for a bank can only recommend that bank's products. A broker searches across multiple lenders. The title alone doesn't tell you which you're dealing with, so ask directly: How many lenders do you search across, and are there products you can't access? A whole-of-market broker will usually search across dozens of lenders.
