Mortgage Broker vs Bank: Which Should You Actually Use?
Published 2026-07-17 · Updated 2026-07-17 · ~9 min read · Author bio ↓
A bank can only offer you its own mortgages, and assesses you against a single rulebook. A whole-of-market broker compares lenders across the market and knows which ones will accept your circumstances before you apply. If your case is simple and you have time to compare, going direct is fine. If your income, credit file or timescale is non-standard, a broker usually saves you more than it costs.
- A bank sells you its own shelf. It is not comparing anything on your behalf.
- The real value of a broker is criteria knowledge, not rate-hunting. Knowing who says yes matters more than knowing who is cheapest.
- Going direct is genuinely fine for straightforward employed cases with a clean file and a good deposit.
- Ask whether the adviser is whole-of-market or tied. Firms are required to tell you.
- Fees vary, see our guide on whether mortgage brokers charge a fee.
What does a bank actually do for you?
When you apply to your bank, you are not getting advice about the mortgage market. You are getting a product from one lender's range, assessed against that lender's criteria. If you fit, you get an offer. If you do not, you get declined, and you find out the hard way, after a credit search has already been recorded.
That is not a criticism. A bank is doing exactly what it exists to do. The problem is that people often mistake it for a comparison. It is not one.
The most expensive thing we see is not a slightly higher rate. It is a decline. An applicant spends three weeks with their own bank, gets turned down on affordability or a credit marker, and has to start again, often after the seller has lost patience. A lender that fits your file first time is usually worth more than a fractionally better headline rate.
What does a broker do that a bank cannot?
- Compares lenders, not products. The question is not just "which rate is lowest" but "which lender will accept this income, this deposit and this credit file".
- Knows criteria before you apply. Lenders differ enormously on self-employed income, bonuses, contract work, benefits, age, property type and adverse credit. That knowledge is the actual job.
- Packages the case. The same set of accounts presented two different ways can produce two different decisions. Underwriters have expectations, and meeting them matters.
- Protects your credit file. A broker aims to submit one application to one lender likely to say yes, rather than leaving a trail of hard searches.
- Handles the chasing. Valuations, solicitors, missing documents. Someone has to chase it. With a bank, that someone is you.
- Advises on protection sensibly. A mortgage is the largest debt most people take on. Cover should be proportionate, not padded.
Broker vs bank, the honest comparison
| What matters | Whole-of-market broker | Going direct to one bank |
|---|---|---|
| Lenders considered | Many, across the market | One. That bank's own range |
| Criteria knowledge | Known before you apply | Discovered by being accepted or declined |
| Non-standard income | Matched to a lender that suits it | Assessed against one fixed rulebook |
| Direct-only deals | Cannot access some of them | Can access its own direct-only products |
| Admin and chasing | Handled for you | You manage it |
| Cost | Fee-free or a disclosed fee £96 on a successful Decision in Principle, then £480 on completion | No broker fee, but no wider search |
| Best suited to | Complex income, adverse credit, tight timescales, or anyone who would rather not do it themselves | Straightforward employed cases with a clean file and time to compare |
Notice that the bank column is not empty. Direct-only products genuinely exist, and any broker who tells you otherwise is overselling. The honest position is that both routes have a place, and which one wins depends entirely on your circumstances.
When is going direct the better choice?
We will say this plainly, because a guide that only ever recommends the person who wrote it is not a guide, it is an advert.
- You are employed with clean payslips, a clean credit file, and a deposit of 15% or more.
- Your existing lender has offered a competitive product transfer, no legal work, no valuation, no new affordability assessment. That is often hard to beat.
- You have the time and the appetite to compare deals yourself and understand the trade-offs.
- The lender you want is direct-only and its product is genuinely the best fit.
If two or three of those describe you, going direct is a perfectly sensible decision, and we will tell you so on the phone rather than after you have paid us.
Whole-of-market, multi-tied and tied advisers
Not every "mortgage adviser" is comparing the market. There are three broad categories, and firms are required to tell you which one they are:
- Tied. Can recommend products from one lender only. Most in-branch bank advisers are effectively in this position.
- Multi-tied. Can recommend from a limited panel of lenders, better than one, but still a fenced garden.
- Whole-of-market. Can advise across products from the mortgage market generally. Not literally every deal in existence, but far wider than any single bank.
Ask the question directly. "Are you whole-of-market, and how many lenders do you have access to?" A straight answer is a good sign. [VERIFY: our own position and lender panel size]
What does each option cost?
A bank charges no broker fee. That does not make it free, the lender's own margin is priced into the product either way. Brokers are paid in one of two ways: a procuration fee from the lender on completion, a fee from you, or a combination of the two. Whichever applies, it must be disclosed to you in writing before you commit to anything.
Our fee position is £96 on a successful Decision in Principle, then £480 on completion, and we state it before you commit to anything. For a fuller breakdown, read our guide on whether mortgage brokers charge a fee.
Not sure which route suits you? A 15-minute call is usually enough to tell you whether a broker would actually add anything in your case, and we will say so if it would not.
Get in touchCommon questions
Is it cheaper to go direct to a bank?
Not necessarily. A bank has no broker fee, but it can only offer its own products. If a lender you cannot see offers a lower rate, or accepts your income where your bank does not, going direct can cost you more overall than a broker fee would have.
Do banks offer deals brokers cannot get?
Occasionally, yes. Some lenders keep certain products direct-only. A good broker will tell you when that is the case rather than pretending the whole market runs through them.
What is a tied adviser?
A tied or multi-tied adviser can only recommend products from one lender or a limited panel. Whole-of-market means advice across a far wider range. Always ask which one you are speaking to, firms must tell you.
Will a broker application be approved faster?
Often, because the case is packaged the way that lender's underwriters expect and submitted to a lender likely to accept it. Speed is never guaranteed and depends on the lender and the complexity of the case.
Can I use a broker and my bank at the same time?
You can speak to both, but you should not have two full applications running with the same lender at once, multiple hard credit searches in a short window can work against you.
When is going direct genuinely the better option?
When you are employed with straightforward payslips, have a clean credit file, a healthy deposit, and your existing lender is offering a competitive product transfer with no legal work required.
