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

Most people go straight to their bank when they need a mortgage. A broker typically finds a better deal, handles the paperwork, and costs nothing. Here's how it actually works.

Guide · Mortgages & buying a home

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. That commission is paid by the lender rather than added to your rate as a separate charge, though you should still ask any broker how they are paid; 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:

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 — a declined application is not itself recorded, but the hard credit search behind it is, and several in a short period can count against you — 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

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.

Questions people actually ask

Does using a mortgage broker cost me anything?

Usually not. Most residential brokers are fee-free: the lender pays them a procuration fee — typically around 0.35% of the mortgage value — when your mortgage completes, and this is disclosed to you during the process. Lenders factor that fee into their standard pricing rather than adding it to your rate as a separate charge. Some brokers do charge you directly, typically £300–£500, either alongside or instead of the lender's fee — this is more common for complex cases such as self-employed income, adverse credit or unusual properties, where the broker's time is significant. The one rule that never changes: ask how a broker is paid before you commit, so there are no surprises later.

Will speaking to a broker affect my credit score?

Speaking to a broker and getting their recommendation doesn't touch your credit file at all — the search happens when an application goes to a lender. A full mortgage application involves a hard credit search, which is recorded and visible to other lenders. A declined application is not itself recorded, but the hard search behind it is, and several hard searches in a short period can count against you. That's a big part of a broker's value: they know which lenders are most likely to accept your particular situation, so you apply once, to the right lender, rather than speculatively to several. If you're getting an agreement in principle, ask whether the lender uses a soft or hard search first — many use soft searches, but not all.

What does whole-of-market actually mean?

A whole-of-market broker can search products from any lender that works with intermediaries — hundreds of mortgage products from dozens of lenders, including deals not available directly to the public. That's the broadest comparison you can get, and most independent brokers work this way. A tied or restricted broker can only offer products from a set panel of lenders, or from a single lender — your bank's mortgage adviser, for example, can only offer your bank's own products, which is a significant limitation when you're trying to find the best deal across the market. It's the first question to ask any broker: if they're not whole-of-market, you're not seeing the full picture, however good the deal in front of you looks.

Should I get a mortgage in principle before viewing houses?

Yes — it's one of the most useful things you can do before you start seriously viewing. A mortgage in principle from a broker gives you a clear budget, so you look at homes you can actually afford rather than guessing. It shows sellers and estate agents that you're a credible buyer, which matters in a competitive market. And it speeds the process up significantly once you find the right property, because the groundwork on your income and deposit is already done. While you're at it, work out the full cost of the purchase — deposit, stamp duty, legal fees, surveys and moving costs — with our cost of buying a home calculator, so the budget you set covers everything, not just the price.
