Mortgage Broker or Bank? How to Avoid Paying More Than You Need To

This article has been published as part of an advertising collaboration.

Choosing a mortgage broker rather than going directly to a bank can sometimes save you money, but there is no guarantee that it will. A broker may compare mortgages from a much wider range of lenders and help you avoid products that don't fit your circumstances, while a bank adviser will normally be restricted to that lender's own mortgages.

The cheapest route depends on the interest rate, fees, lender criteria, broker charges and which products each route can actually access.

That distinction matters because a mortgage can last for decades, so even relatively small differences in the cost of borrowing can become significant. At the same time, paying a broker hundreds of pounds for a mortgage you could have obtained directly at the same price doesn't make financial sense purely because professional advice sounds reassuring. The aim should be to compare what each route gives you and what the complete mortgage will cost.

This guide covers regulated residential mortgage advice in the UK and provides general information rather than personal financial advice. Your circumstances, income, deposit, property and credit history can all affect which mortgages are available to you. If you take advice, check that the firm is properly regulated before giving it personal or financial information.

What does a mortgage broker actually do?

A mortgage broker acts as an intermediary between you and mortgage lenders, assessing your circumstances before recommending a product they consider suitable from the range available to them. A broker can also help identify lenders whose affordability rules and lending criteria are more likely to fit your application.

MoneyHelper says brokers can deal with the lender on your behalf, help with paperwork and take mortgage costs and features into account beyond the headline interest rate.

That can make the service particularly useful when you don't know where to start. Rather than approaching one lender at a time, the broker can look at your income, deposit, borrowing requirement and other circumstances before narrowing the field. You still need to check how broad that search actually is, because different brokers have access to different lenders.

The broker's role can continue after the initial recommendation as well. They may help prepare an application, answer lender questions and communicate with the lender while the mortgage is being assessed. That administrative support has a value of its own, even where the mortgage rate itself isn't lower than something you could have found directly.

Is a mortgage broker cheaper than going directly to a bank?

A mortgage broker can be cheaper, but going directly to a lender can also cost less. MoneyHelper notes that lender-connected advisers normally only recommend their own lender's products, while brokers can offer mortgages from several lenders. Some lenders also have rates or discounts reserved for existing customers, so a wider broker search doesn't automatically include every possible deal.

The useful comparison is therefore between the best suitable mortgage you can obtain through the broker and the best suitable deal you can obtain directly. Include the broker's fee, mortgage product fees and any other costs rather than looking only at the monthly repayment. If the same mortgage is available directly and the broker wants £500 for arranging it, you need to decide whether the advice and application support are worth that additional cost.

Recent discussions among UK homebuyers show that this is exactly what people are questioning. Some borrowers report finding the same lender or a cheaper direct product after receiving a broker recommendation, while others value brokers for handling complex circumstances or monitoring rates during an application. Those individual experiences aren't proof that either route is better, but they reinforce the case for comparing both before committing.

Route	Potential advantage	What to check
Direct to your bank	No separate broker fee and possible customer-only products	You are normally comparing that lender's mortgages only
Another lender directly	Can access mortgages sold directly to customers	You need to research eligibility and manage the application
Mortgage broker	Can compare multiple lenders and advise on suitability	Check fees, lender panel and whether direct-only deals are excluded
Whole of market broker	Wider mortgage search	“Whole of market” does not necessarily mean every mortgage available
Existing lender product transfer	Can sometimes reduce administration when remortgaging	Compare it with new-lender deals before accepting

Does a whole of market mortgage broker really search the whole market?

A whole of market broker can search more widely than an adviser restricted to one lender, but that doesn't necessarily mean every mortgage available to UK borrowers. MoneyHelper specifically warns that brokers describing themselves as whole of market might not cover everything. Ask the broker what their service includes rather than relying on the phrase alone.

Some lenders or products may sit outside the broker's panel, while customer-specific deals may only be available by going directly to a lender. Specialist products such as certain buy-to-let or interest-only mortgages may also require an adviser who works in that part of the market. A broad panel is useful, but breadth should not be confused with universal access.

Before agreeing to use a broker, ask which lenders they can consider and whether there are major lenders they don't deal with. You can then carry out a quick direct comparison yourself before accepting the recommendation. That small check gives you a better idea of whether the broker is genuinely widening your options.

How much does a mortgage broker cost?

Mortgage broker costs vary because some brokers charge the customer, some receive commission from the lender and some use both methods. MoneyHelper says the customer charge can be a flat fee, hourly amount or percentage of the mortgage, while other brokers charge no up-front customer fee because the lender pays commission. You must be told how the advice will be paid for and what it will cost before you commit.

MoneyHelper's current guide gives a broad indication of £300 to £1,000, or around 0.35% to 1% of the mortgage amount, where a mortgage adviser charges the customer rather than relying solely on commission. Those figures are a guide rather than a standard tariff, and individual brokers can price their service differently. A broker describing their service as fee-free isn't necessarily working unpaid, because lender commission may cover the cost.

Be particularly careful if you are offered the option to add an advice fee to the mortgage. MoneyHelper warns that you will then pay interest on that fee along with the rest of the borrowing. A £500 fee added to a long mortgage therefore costs more than £500 by the time it has been repaid.

Why the lowest mortgage rate may not be the cheapest deal

A lower interest rate doesn't automatically produce the cheapest mortgage once product fees and other charges are included. A mortgage with a slightly higher rate but no large arrangement fee can sometimes cost less over the period you expect to keep it. Compare the numbers that apply to your borrowing rather than ranking products by rate alone.

The Annual Percentage Rate of Charge, or APRC, is one useful comparison figure because it incorporates interest and mortgage charges over the assumed full mortgage term. MoneyHelper also recommends checking administration costs and early-exit penalties when comparing fixed, tracker and variable mortgages. The mortgage illustration given to you during regulated advice should set out the repayments, fees, overall cost, APRC and features such as overpayment penalties.

APRC still needs context because many borrowers don't keep the same mortgage product for the full term used in the calculation. If you expect to switch again after a two or five-year deal, look closely at the cost during that period as well as the long-term illustration. Product fees, cashback, valuation offers and early repayment charges can change which deal actually works out cheaper for you.

Could a broker help you avoid unsuitable applications?

A broker can help identify lenders whose criteria are more likely to fit your circumstances before you make a formal application. That doesn't guarantee approval, but it may reduce the temptation to make repeated applications to lenders that were unlikely to accept you in the first place.

MoneyHelper specifically notes this benefit for borrowers whose credit history may make finding a mortgage harder.

Credit searches deserve some care here. A mortgage agreement in principle can involve either a soft or hard credit search depending on the lender, while a formal mortgage application normally involves a hard search. Too many hard searches within a short period can affect your credit rating, so check what type of search will be carried out before submitting several applications.

Using a broker doesn't itself create a special protection against credit searches. Its practical value is that a knowledgeable adviser may be able to narrow down suitable lenders before you reach the formal application stage. That is a very different claim from saying a broker can guarantee an application won't affect your credit file.

When can a mortgage broker be particularly useful?

A mortgage broker may offer more value when your financial circumstances don't fit the simplest lender criteria. Self-employed income, contract work, irregular earnings, previous credit problems or an unusual property can all make lender selection more important because banks don't assess every situation in the same way. A broker familiar with those circumstances may know which lenders are more likely to consider the application.

That doesn't mean somebody with a standard salaried income won't benefit from advice. First-time buyers may value having the mortgage terminology and application process explained, while busy borrowers may prefer paying someone to manage communication and paperwork. The benefit needs to be weighed against any broker fee rather than treated as an automatic saving.

If you are still deciding what sort of property your budget can support, my guide to choosing a family home that works for your finances looks at the wider costs beyond the mortgage itself. Mortgage affordability is only part of the calculation because surveys, legal fees, maintenance and the ongoing cost of the property still have to fit your household finances.

What protection do you get from regulated mortgage advice?

Regulated mortgage advice gives you consumer protections that you don't have in quite the same way when making the decision entirely by yourself. MoneyHelper says an adviser should recommend an appropriate mortgage for your needs and circumstances, and a complaint about unsuitable regulated advice can ultimately be taken to the Financial Ombudsman Service where appropriate.

The Financial Conduct Authority Firm Checker allows you to check whether a firm has the permissions it needs before you use it. The FCA says mortgage brokers carrying out regulated activities must either be authorised themselves or operate as an appointed representative of a firm with the relevant permissions. Checking before sharing bank statements, payslips or other sensitive information is a sensible part of choosing an adviser.

Regulation does not mean every mortgage recommendation will turn out to be the cheapest possible deal. It means the adviser has regulatory responsibilities when giving advice, including assessing suitability and explaining the service and costs. You should still understand what has been recommended before signing anything.

What changes if you're buying a property outside the UK?

Mortgage advice is country-specific, so UK FCA rules shouldn't be carried over to a property purchase overseas. In Australia, for example, somebody looking for mortgage brokers Newcastle would be dealing with Australian credit regulation and local lending criteria rather than the UK mortgage system. The linked broker describes its service as covering Newcastle, Maitland, Singleton and the Central Coast and operates under an Australian Credit Licence.

That distinction matters if you are researching property abroad from the UK. Mortgage terminology can sound familiar across different countries while lender rules, consumer protections, fees and borrowing structures differ considerably. Use locally regulated advice for the country in which you are actually borrowing rather than assuming a UK mortgage guide applies internationally.

The same principle applies to overseas property guides generally. My existing guide to buying a house in Spain explains some of the different costs and legal steps involved there. Buying internationally needs its own research rather than simply transferring a UK home-buying checklist to another market.

Should first-time buyers use a mortgage broker?

A first-time buyer doesn't automatically need a mortgage broker, but advice can be useful when the terminology, affordability rules and application process are unfamiliar. A broker can explain the mortgages available through their service, assess likely lender criteria and help you prepare the documentation needed for an application. The question is whether that help is worth any fee being charged.

If your finances are relatively simple, it is still worth checking direct lender and comparison-site options before paying a large broker charge. MoneyHelper describes comparison websites as a useful starting point, while warning that different comparison services don't all show the same results. Comparing more than one source can therefore give you a useful benchmark before speaking to an adviser.

The same applies if an estate agent introduces you to its preferred broker. You aren't required to use that adviser simply because you are buying a property through the agent. Check the broker's costs, FCA status and market coverage in exactly the same way you would for somebody you found yourself.

Can a broker help when you remortgage?

A broker can help compare remortgage options, but your existing lender should remain part of that comparison. When a fixed or discounted deal ends, you will normally move onto the lender's standard variable rate unless another arrangement is made, and MoneyHelper says those rates are usually higher than other mortgage rates that may be available. A product transfer from your existing lender can sometimes compete with moving to a different lender.

Switching isn't automatically worthwhile either. A new product may have an arrangement fee, while leaving your current deal early can trigger an early repayment charge. Legal, valuation and administration costs may also apply when changing lenders, so calculate the actual saving after all of those charges.

This is another situation where a broker's value should be measurable. Compare the recommendation with the product transfer offered by your current lender and any suitable direct mortgages you can find yourself. If the broker's option is cheaper after every cost has been included, you have a clearer financial reason for using it.

What documents will a mortgage application involve?

A mortgage lender will normally need evidence that supports the income, expenditure and identity information in your application. The precise documents depend on your circumstances, but bank statements, payslips or other income evidence, proof of deposit and identification are common parts of the process. A self-employed applicant may need different evidence from somebody receiving a regular salary.

A broker can help you understand what a particular lender expects before the application is submitted. That can save time where documents need to be obtained from an accountant, employer or another source, but the borrower remains responsible for supplying accurate information. Don't alter or omit information simply because you think it will make the application easier.

It is also worth preparing financially before you begin applying. Avoid taking on unnecessary new borrowing where possible and check your credit reports for errors before a lender starts assessing you. The fewer surprises you discover halfway through the application, the easier it is to decide which lender and mortgage route genuinely fits your position.

What should you ask a mortgage broker before agreeing to use them?

The most useful questions focus on cost, coverage and what you will actually receive for the money. Ask how the broker is paid, whether you owe a fee if the purchase falls through, which lenders they can access and whether their search excludes any significant direct-only products. You should also know when any fee becomes payable and whether it will be refunded if the mortgage doesn't complete.

Ask what happens after the application is submitted too. Some services remain involved until completion and may monitor rates, while others provide a more limited service. If you are paying several hundred pounds, knowing exactly where the broker's work begins and ends makes it much easier to judge the value.

The initial conversation is often free, but don't assume that it is. MoneyHelper recommends comparing different firms and says most mortgage advisers don't charge for the first conversation, while advising borrowers to confirm this before speaking to them. That gives you an opportunity to compare service and fees before choosing one.

So, can using a mortgage broker actually save you money?

Yes, a mortgage broker can save you money if they find a suitable mortgage whose overall cost beats the alternatives available to you, or if their knowledge helps you avoid an expensive or unsuitable borrowing decision. They can also save time by narrowing lender options and managing parts of the application. Neither benefit means every borrower should automatically use one.

Going directly to a lender can still be the cheaper route if you qualify for a strong direct deal, particularly where the alternative involves a substantial broker fee. The sensible test is to compare the broker's recommendation against direct alternatives using the same mortgage amount and expected deal period. Include interest, product fees, broker fees, early repayment charges and any other relevant costs before deciding.

For a financial commitment this large, a little duplication at the comparison stage is worthwhile. Check the broker, check a couple of direct options and read the mortgage illustration rather than accepting the first attractive rate you are shown. The goal isn't to prove that brokers or banks are cheaper as a group, it is to find the route that costs less and suits your own circumstances.

Frequently asked questions

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

Either route can work out cheaper. A broker may find a more suitable mortgage across several lenders, while going direct can avoid a broker fee and may give you access to deals that the broker cannot offer.

How much does a mortgage broker cost in the UK?

Some mortgage brokers charge no customer fee because they receive commission from the lender, while others charge a fixed fee, hourly rate or percentage of the mortgage. Ask for the full cost and how the broker will be paid before agreeing to use them.

Does a whole of market mortgage broker compare every mortgage?

Not necessarily. MoneyHelper says whole of market brokers can offer a wider range of products, but they may not cover everything, so ask exactly which lenders and mortgages are included in their search.

Can a mortgage broker help if I am self-employed?

A broker can be useful where your income or circumstances do not fit a typical salaried application because different lenders use different criteria. The broker still cannot guarantee acceptance, and you will need to provide the evidence requested by the lender.

Do mortgage brokers affect your credit score?

Speaking to a broker does not itself damage your credit score. Mortgage applications and some agreements in principle can involve credit searches, so ask whether a lender will carry out a soft or hard search before proceeding.

How do I check if a UK mortgage broker is regulated?

Use the FCA Firm Checker or Financial Services Register before taking regulated mortgage advice. Mortgage brokers carrying out regulated activities must be FCA-authorised or operate as an appointed representative of a firm with the relevant permissions.

Should I use a mortgage broker when remortgaging?

It can be worth comparing a broker's options with a product transfer from your existing lender and deals available directly elsewhere. Include broker fees, mortgage fees and any early repayment charges before deciding.
