When to use a mortgage broker — and why it usually beats going direct.

A mortgage is almost certainly the largest financial commitment most people ever make. The rate you pay — even a difference of 0.3% — can add up to thousands of pounds over a five-year fix. Yet most people approach the mortgage market in the least effective way possible: by calling their existing bank and taking whatever is offered.

A good mortgage broker searches the whole market, knows which lenders are most likely to accept your application, handles the process from start to finish, and in most cases charges you nothing. The case for using one is strong almost regardless of your situation.

What a mortgage broker actually does

A broker acts as an intermediary between you and mortgage lenders. They assess your situation — income, deposit, credit history, property type, employment status — and search the available market for the most suitable options. In the UK, a whole-of-market broker has access to hundreds of mortgage products from dozens of lenders, including deals not available directly to the public.

They handle the application on your behalf, liaise with the lender and your solicitor, and manage the process through to completion. For a first-time buyer navigating this for the first time, that support is genuinely valuable beyond just finding a good rate.

How brokers are paid

Fee-free brokers

Most residential mortgage brokers charge you nothing. They're paid a procuration fee by the lender — typically around 0.35% of the mortgage value — when the mortgage completes. This is disclosed to you as part of the process. Your mortgage rate is not higher as a result; lenders factor this into their standard pricing.

Fee-charging brokers

Some brokers charge a fee directly to you — typically £300–£500 — in addition to or instead of the lender's procuration fee. This is more common for complex cases (self-employed, adverse credit, unusual properties) where the broker's time is significant. Always ask upfront how they charge before proceeding.

Whole-of-market vs restricted

There are two types of mortgage broker:

• Whole-of-market brokers can search products from any lender that works with intermediaries. This gives you the broadest possible comparison. Most independent brokers are whole-of-market.
• Tied or restricted brokers can only offer products from a panel of lenders, or a single lender. Your bank's mortgage adviser, for example, can only offer your bank's products. That's a significant limitation when you're trying to find the best deal across the market.

Always ask whether a broker is whole-of-market before using them. If they're not, you're not seeing the full picture.

When a broker is especially valuable

Self-employed or complex income

Lenders treat self-employed applicants differently, and some are significantly more flexible than others. A broker who knows which lenders work best for your income structure can save you a rejection — which damages your credit file — as well as finding a better rate.

Less than perfect credit history

A missed payment or CCJ doesn't automatically mean you can't get a mortgage — but it does mean the lender choice matters enormously. An experienced broker knows which lenders are most likely to accept your application without you having to apply speculatively.

Unusual property types

Non-standard construction, listed buildings, short leases, high-rise flats — many lenders won't touch these. A broker who works with these regularly knows where to go and what to expect.

Remortgaging at the end of a fix

When your fixed rate ends, your lender will offer a new rate. It is almost never the best available. A broker searches the whole market and handles the switch — often with no cost to you and minimal effort.

Questions to ask before you commit

• Are you whole-of-market?
• How do you charge — fee-free, or a direct fee from me?
• How many lenders do you have access to?
• Will you handle the full application and liaise with the lender?
• What happens if my application is declined?

One thing to know: getting a mortgage in principle from a broker before you start seriously viewing properties gives you a clear budget, demonstrates to sellers and estate agents that you're a credible buyer, and speeds up the process significantly once you find the right property.

Going direct to your bank: when it makes sense

There are situations where going direct can be sensible — typically if you have a large deposit, straightforward employed income, and a good relationship with a lender who consistently prices competitively. But you should only do this after checking the market through a broker first, so you know what you're comparing against.

Using a broker costs you nothing in most cases and takes the work off your plate. The downside risk of not using one — missing a materially better deal or applying to the wrong lender — is real and measurable.
