Do mortgage brokers get better rates? Sometimes. A small number of lenders sell certain products only through brokers, and a broker can compare the whole market in one sitting. What no honest broker can do is promise a lower rate than you could find yourself, because on plenty of mortgages the broker rate and the direct rate are the same.
This page covers how broker-only rates work, what a lower rate is worth in pounds, where broker access matters most and where it makes little difference, and what it costs to use us.
What Are Broker-Only Mortgage Rates?
A broker-only rate is a product a lender sells through intermediaries and not through its own branches, website or app. You will not find it on the lender’s public rate table, and many of these deals never appear on comparison sites either. Lenders do this for a few reasons. Some want applications that arrive already checked, with the documents in order and the income explained. Others run a specialist range for landlords, limited companies or unusual properties, and would like those cases to come through someone who understands them. A few price their direct and broker channels separately.
You will sometimes hear these called semi-exclusive deals. The word is fair, because more than one broker can usually offer the same product. It only means you cannot walk into a branch and ask for it. Which lenders have a broker-only range changes from month to month, so we check each time and do not assume.
Do Mortgage Brokers Get Better Rates Than Going Direct?
Often the same, sometimes better, occasionally worse. Where a lender sells an identical product both ways, the rate normally matches, and we will tell you when that is the case. The gain, when there is one, comes from three places. A broker-only product may exist that the lender’s own channel never shows you. A broker can compare dozens of lenders on the real cost, which includes fees and not only the headline rate. And a broker knows which lender is likely to accept your circumstances, which counts for more than a small price difference if the cheapest lender would turn you down.
That last point is the one most people miss. A rate you cannot get is not a rate. The limits of a single lender are covered in why going direct to your bank can limit your mortgage options.
Do not expect a broker to win on every case. If your own bank has the best deal for you, we will say so and you can take it.
A lower rate is worth pounds a month, so it pays to run the numbers
What a Lower Rate Is Worth
A table shows the size of the gap more clearly than a paragraph. These are illustrative rates on a £250,000 repayment mortgage over 25 years, with the saving measured across a five-year fixed period. They are examples and not quotes. For where rates actually sit at the moment, our current mortgage rates page keeps dated ranges.
| Rate | Monthly payment | Saving per month | Saving over five years |
| 5.00% | £1,461 | none | none |
| 4.90% | £1,447 | £15 | £872 |
| 4.75% | £1,425 | £36 | £2,171 |
| 4.50% | £1,390 | £72 | £4,314 |
A tenth of a point is worth about £15 a month. A quarter of a point is about £36 a month, or a little over £2,000 across a five-year fix. Half a point passes £4,000. That is real money, but it comes to hundreds of pounds a year, not the thousands some broker adverts suggest. Fees can cancel a small rate gain completely, so the total cost over the fixed period is the figure to compare. The true cost of a mortgage shows how product fees, valuation fees and exit fees change the picture, and you can test your own numbers in our simple mortgage calculator.
Can a Mortgage Broker Get You a Bigger Mortgage?
Sometimes, and the reason has little to do with the rate. Lenders work out affordability in different ways. Income multiples vary between lenders and between types of borrower, and some count bonuses, overtime, second jobs or rental income more generously than others. Two lenders can look at the same applicant and arrive at loan amounts that differ by a surprising amount. A broker’s job is to find the lender whose rules suit your income.
The method behind those calculations is in mortgage affordability explained, the typical multiples are on how much you can borrow, and how lenders check income shows what underwriters ask to see.
None of this lets anyone get around affordability rules. A regulated lender still has to be satisfied that you can repay, and nobody can promise a figure before that lender has assessed the application.
Where Broker Access Matters Most
For a straightforward purchase with a good deposit and a salary, the gap between broker and direct is usually small. It widens as the case becomes less typical.
Buy-to-let is the clearest example. Many landlord lenders deal only with brokers, so a landlord who goes to a high street bank sees a fraction of the market. Limited company lenders, portfolio lenders and those who accept unusual properties are largely closed to direct applicants. The mechanics are on our buy-to-let mortgages page and, for purchases through a company, limited company buy-to-let mortgages.
Self-employed and contractor borrowers see the same effect, because lenders differ so much in how they read accounts, retained profit and day rates. Borrowers with a poor credit history or a small deposit often find that the lenders willing to consider them sit mainly on broker panels. Bad credit mortgages and self-employed mortgages explain how that works, and how brokers place difficult-to-place mortgage applications covers the hardest cases.
Broker or Comparison Site?
Comparison sites are good for a quick look at headline rates. They have limits. They show a rate and a fee, but they do not know whether you meet the lender’s criteria, coverage varies from site to site, and they cannot warn you that a lender will treat your bonus income badly. Use one to get a feel for the market, then ask a broker to confirm what is available to you in practice. Once you have a shortlist, our comparison of fixed and tracker mortgages explains how to weigh the two main rate types.
How Much Does a Mortgage Broker Cost?
Our first conversation is free. After that, the lender normally pays us a procuration fee when your mortgage completes. In some cases we also charge a broker fee, and if we do you will have the amount in writing before you commit to anything. Neither the fee nor the commission changes which lender we recommend. You can check any broker on the Financial Conduct Authority register, and you should expect every adviser to answer the same question in the same way.
Questions to Ask Any Broker Before You Start
Ask how many lenders they can place you with and whether any are closed to them. Ask how they are paid and whether you will be charged a fee. Ask who will run your case and how you will see where it stands. Ask whether the rate they quote includes every fee, and whether a lender has confirmed it will accept your income.
An agreement in principle gives you a first answer without a full application, and agreement in principle explained shows what it does and does not tell you. If you have already been turned down after one, see what happens when a mortgage is declined after an agreement in principle.

Frequently Asked Questions
Do mortgage brokers get better rates than banks?
Sometimes.
Where a bank sells the same product directly and through brokers, the rate is usually identical, so the advantage comes from broker-only products, from comparing many lenders, and from knowing which lender will accept your circumstances. If your own bank has the best deal for you, a broker will say so.
What is a broker-only mortgage?
A broker-only mortgage is a product a lender sells only through intermediaries.
You cannot apply for it at a branch or on the lender’s website, and it often does not show on public rate tables. Lenders use this route for specialist ranges such as buy-to-let and limited company lending, or to receive applications that arrive already checked.
Are broker-only mortgages better?
Not automatically.
A broker-only product can be cheaper or more flexible than a lender’s standard range, but it can also carry a higher fee, and it may suit some borrowers and not others. The only fair test is the total cost over the fixed period and whether the lender will accept your case.
Can a mortgage broker get you a bigger mortgage?
Sometimes.
Lenders use different income multiples and count bonuses, overtime and rental income differently, so one may lend more against the same income than another. A broker finds the lender whose rules suit you, but cannot override affordability checks or guarantee an amount before the lender has assessed your application.
How much does a mortgage broker charge?
It depends on the broker.
With us the first conversation is free, the lender normally pays us a procuration fee when the mortgage completes, and if a broker fee also applies you will have the amount in writing before you commit. Ask any broker the same question at the start.
Can a broker access buy-to-let deals I cannot get myself?
Often yes.
Many specialist buy-to-let lenders, including those for limited companies and portfolios, take cases only through brokers. A high street bank offers a small part of the landlord market, so a broker can show you products you would not see by applying directly.

A broker cannot promise you a lower rate, but a good one can show you the full market, explain what each option costs, and tell you plainly when your own bank is the right answer.
