Yes—a mortgage broker can make the mortgage part of buying your first home easier by comparing lenders’ criteria, helping identify options that fit your circumstances, and supporting you with the application. That help can be especially useful if you have a small deposit, are self-employed, have a short employment history or low credit score, or are buying through shared ownership. But a broker cannot guarantee approval, the lowest rate, or an easier property purchase. Whether advice is worthwhile depends on the broker’s lender coverage, service and charges—and on how comfortable you are comparing mortgages and applying directly.
This guide is about buying in the UK. Mortgage regulation, purchase taxes and government schemes differ across the UK and from country to country; check the rules that apply where the property is located.

What does a mortgage broker do?
A mortgage broker is an intermediary between you and mortgage lenders, not the lender itself. Depending on the service, a broker may assess your circumstances, search lenders, explain which criteria may fit, recommend a mortgage and help manage the application and lender contact. A lender’s own adviser, by contrast, generally advises on that lender’s products rather than comparing the wider market.

A broker may compare multiple lenders, but the range can still be limited to a particular panel. A lender’s adviser may know that lender’s products in detail, but will not usually show you mortgages from competitors. Neither route is automatically better for every buyer.

A broker can also help you get an early indication of how much you might be able to borrow before you make offers. GOV.UK recommends getting a decision in principle before viewing properties. It estimates how much a lender may be willing to lend, but it does not commit you to taking that lender’s eventual mortgage. Ask whether the lender uses a soft or hard credit search for this step.
A decision in principle is an estimate, not a formal mortgage offer. The lender will still assess your application and the property before deciding whether to lend. Treat the amount shown as a possible borrowing limit rather than a target: what a lender might offer is not necessarily what fits your household budget.
The lender—not the broker—makes the final lending decision. An adviser can help you find possible matches and submit an application, but cannot promise that a lender will approve it or offer a particular rate. The Financial Conduct Authority (FCA) has noted that a significant fraction of homebuyers use brokers to help find a mortgage that meets their needs rather than purchasing directly from lenders. That describes the role brokers play; it is not a guarantee of a better result.

When might a broker make buying your first home easier?
Advice may be most useful when your finances or purchase are less straightforward, or when you are unsure how to compare mortgage terms. A broker may help you understand which lenders could consider your circumstances, what documents an application needs and how a mortgage’s features affect its cost.
- You have a small deposit. A smaller deposit means borrowing a larger share of the property’s value. That proportion is called the loan-to-value ratio, or LTV. For example, on a £250,000 home, a £25,000 deposit and £225,000 mortgage make the LTV 90%. A larger deposit reduces the amount borrowed and may open access to a wider range of deals or lower rates, but it does not guarantee a particular rate.
- You are self-employed. Lenders may assess self-employed income differently from salaried income and ask for evidence such as tax returns and business accounts. The exact documents required depend on the lender.
- You have only recently changed jobs or have a short employment history. Lenders’ requirements vary, so it can help to understand which criteria might apply before you make an application.
- You have a low credit score or an unusual circumstance. GOV.UK notes that these factors can limit the mortgages available. A broker may help identify lenders whose criteria could be more compatible, but cannot remove the lender’s eligibility checks.
- You are buying through shared ownership. The purchase route can affect what you need to explain and what lenders will consider. MoneyHelper identifies shared ownership as a situation where individual advice may help.
These circumstances do not automatically make a mortgage impossible, and they do not guarantee that a broker will find a suitable product. The useful question is whether the adviser understands the specific issue and can explain which lenders and evidence are relevant. For example, a self-employed buyer should ask what income records the lender is likely to require, rather than assuming every lender uses the same checklist.
Even in these situations, advice is a way to navigate options, not a promise of approval. A lender may still decline an application or offer terms that do not fit your budget.
Should you use a broker or apply directly?
Applying directly may suit a buyer with a straightforward case who is comfortable comparing mortgage illustrations, checking eligibility and handling the application. A broker may suit someone who wants help understanding lender criteria, comparing a range of options or managing paperwork and lender queries. Compare the actual service and costs rather than assuming either route is cheaper or better.

Think about the work you want help with. Are you mainly looking for someone to identify lenders that may consider your circumstances, explain trade-offs between products, or help keep the application moving? Or are you comfortable doing those tasks yourself and contacting lenders? A broker’s value depends in part on the answer. The advice may reduce the amount of comparison and paperwork you handle, but there is no established amount of time or money every first-time buyer saves by using one.
| What to compare | Questions to ask |
|---|---|
| Lender and product coverage | Which lenders and specialist products are included? Are any lenders or direct-only mortgages excluded? |
| Fit with your circumstances | Does the adviser understand your income, deposit, credit history, property and purchase route? |
| Total cost | What will the broker charge, what lender fees apply, and what will the mortgage cost over time? |
| Application support | Who will help gather documents, answer queries and communicate with the lender? |
| Advice and accountability | Is this regulated mortgage advice, and what complaint route applies if the recommendation is unsuitable? |
“Whole of market” should not be taken to mean every mortgage is available through a broker. Some products are available only by applying directly to a lender, and a broker may exclude some lenders or products. Ask for the coverage and exclusions in plain language, especially if you plan to compare a broker’s recommendation with a direct application.
If you compare a broker’s recommendation with a direct offer, compare the same things on both sides: the initial rate, rate type, fees, repayment amount, total cost, and any overpayment or early-repayment terms. Also check whether the recommendation depends on an assumption about your income or deposit that needs to be confirmed. A lower headline rate alone does not establish which option costs less overall.
Using a broker is common, but popularity is not proof of a better outcome. The Financial Conduct Authority’s 2025 consultation paper CP25/11 reports that around 90% of first-time buyers and around 78% of home movers purchased via a broker in 2023, based on FCA analysis of regulatory Product Sales Data. Those figures describe how people bought; they do not show that using a broker caused better rates, faster purchases or higher approval chances.

A broker may charge you, receive commission from a lender, or use both payment methods. Possible buyer fees include flat, hourly or percentage-based charges; there is no single fee arrangement that applies to every firm. “Free” advice may mean the adviser receives lender commission rather than charging you directly, so ask how the service is paid for before proceeding.
Get clear answers to these questions:
- Will I pay a fee, and how much is it?
- Does the broker also receive commission from the lender?
- When does any fee become due?
- Is a fee refundable if my purchase does not complete?
- Will any fee be added to the mortgage?
Ask for the payment terms before you agree to proceed, not just once a mortgage has been recommended. If the adviser charges a fee as well as receiving lender commission, ask how both payments work. A clear explanation lets you compare the cost of the service with applying directly, without assuming that a no-upfront-fee option has no cost to anyone.
There is no universal refund rule established for a purchase that falls through, so ask the broker to explain its own terms before agreeing. If you add a fee to the mortgage, you borrow that amount and pay interest on it while it remains outstanding. Deferring payment in this way does not make the fee cost-free; compare the total borrowing cost.

How should you compare mortgage recommendations?
Do not choose on the headline interest rate alone. A mortgage illustration sets out details that help you compare the product with your budget and plans, including fees, the total cost over the term, the rate type and APRC, repayments, possible rate changes, overpayments and penalties.
Read the illustration alongside the broker’s explanation. Check whether the initial rate is fixed or variable, what happens when it ends, and whether fees or early-repayment charges change the overall value. Consider the monthly payment you can manage, not just the largest amount a lender might offer. Ask the adviser to explain any feature or cost you do not understand, and request a comparison that makes the trade-offs clear.
Look at the full terms, not just the payment at the start. The illustration can help you see how fees affect the total cost over the term, what happens if the rate changes, whether you can make overpayments, and whether penalties apply. These details matter if your plans or finances change. Ask the adviser to explain the consequences of a feature you are unsure about before you decide.
A recommendation can only be assessed against the products and lenders considered. Ask what alternatives were included, whether direct-only deals fall outside the search, and why the recommended option fits your circumstances. A broker may help you compare, but neither an adviser’s recommendation nor the advertised rate is a guarantee of the final terms a lender will approve.
What should you check before choosing a UK mortgage adviser?
Check the firm on the FCA Register before relying on its advice. MoneyHelper says regulated mortgage advice should come with a mortgage illustration and usually a suitability report. These documents give you a way to review what was recommended and why.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Confirm the firm’s status. Search for the adviser or firm on the FCA Register and make sure the details match the business you are dealing with.
- Ask about the market covered. Find out which lenders and products the broker can consider, and what may be excluded.
- Get the payment terms. Confirm fees, lender commission, when charges become due, refund terms and whether a fee could be added to the loan.
- Explain your circumstances fully. Be upfront about income, deposit, credit history and the property or purchase route. Ask what documents the lender is likely to need; requirements vary.
- Read the paperwork. Check the mortgage illustration’s rate, APRC, fees, total cost, repayment details, overpayment terms and penalties. Review the suitability report when provided.
- Keep your own budget in view. A lender’s willingness to lend does not determine what monthly payment is comfortable for your household.
It is reasonable to ask the adviser to explain a recommendation in practical terms: which lenders were considered, why the selected product may fit, what it costs, and what the important limitations are. If you do not understand a fee, condition or repayment feature, ask before proceeding. Keep copies of the illustration, suitability report and fee terms so you can refer back to what was discussed.
MoneyHelper says that if you receive regulated advice and later believe a mortgage was unsuitable, you can complain; if necessary, you may take the complaint to the Financial Ombudsman Service. Without advice, you carry full responsibility for choosing the mortgage. This makes it important to understand which service you are receiving, rather than assuming that every person who helps with an application has made a recommendation for you.

What first-home costs should you budget for besides the mortgage?
A broker can help with the mortgage, but buying a home also involves one-off purchase costs and ongoing expenses. MoneyHelper lists survey fees, solicitor or conveyancer costs, mortgage fees, insurance and tax. GOV.UK also highlights searches, moving costs, repairs or improvements, and—where relevant—leasehold service charges or ground rent.
Stamp duty and related purchase taxes depend on where the property is in the UK and on your eligibility. Check the current rules for the property’s location rather than relying on a general estimate. Include these costs when deciding what deposit and monthly repayment you can realistically afford; money needed for fees or repairs is not available for the deposit.
Recommended Free Tools
Separate costs due around completion from costs you will keep paying after moving in. A survey, legal work, searches and moving costs are tied to the purchase, while insurance, repairs and any leasehold service charges or ground rent can continue afterwards. The precise costs vary by property and purchase, so leave room in the budget for expenses beyond the deposit and mortgage payment.
When discussing affordability, ask the adviser to distinguish the lender’s borrowing estimate from your household budget. Consider the mortgage payment alongside bills, insurance, maintenance and any applicable leasehold charges. The mortgage is a major part of the purchase, but a recommendation cannot account for every future expense unless you bring those costs into the conversation.

If you are unsure about eligibility or have a less straightforward application, speak with a UK-regulated adviser and compare the service, coverage and payment terms before agreeing. If your case is straightforward and you are comfortable comparing illustrations and managing paperwork, compare applying directly as well—while remembering that some broker searches may not include direct-only mortgages.
Either way, start with a realistic full-purchase budget, understand the likely borrowing range before making offers, and read the mortgage illustration carefully before committing. A broker can reduce research and application friction; the lender still decides whether to lend, and the final choice should fit your finances as well as the property.

Does speaking to a mortgage broker affect my credit score?
A conversation with a broker is not itself the same as a lender credit search. If you request a decision in principle, ask the lender whether it will use a soft or hard search, because the approach can differ.

Can a broker guarantee that I will get a mortgage?
No. A broker can help identify lenders whose criteria may fit and assist with an application, but only the lender decides whether to approve it and on what terms.
Can I use a broker and still contact lenders myself?
You can compare routes, but tell the broker if you are also approaching lenders directly so you can understand what each application covers. Ask whether a proposed mortgage is available only through the lender and how any broker fee applies if you proceed elsewhere.
What documents might a first-time buyer need for a mortgage application?
Requirements vary by lender and by how you earn. Self-employed buyers should be prepared for requests such as tax returns and business accounts, and should ask the adviser which evidence applies to their specific application.
Does “whole of market” mean a broker searches every mortgage?
Not necessarily. A broker may use a lender panel or exclude some products, and some mortgages are available only by applying directly to the lender. Ask which lenders and products are covered before relying on a comparison.
Is mortgage advice free if the broker does not charge me?
The broker may receive commission from a lender, or may use another payment arrangement. Ask whether you will pay a fee, whether the broker also receives commission, when any fee is due, and whether it can be added to the mortgage.
What does a mortgage illustration tell me?
It helps you compare the rate and rate type, APRC, fees, total cost over the term, repayment details, possible rate changes, overpayment terms and penalties. Read it against your budget, not just the headline rate.
Can I complain if I think the mortgage recommendation was unsuitable?
MoneyHelper says a buyer who receives regulated advice can complain if a mortgage later proves unsuitable, including to the Financial Ombudsman Service if needed. Check that you are receiving regulated advice, rather than only help with an application.

A mortgage broker can make the mortgage process more manageable by helping you compare lender criteria, understand product terms and handle an application—especially if your circumstances are less straightforward. But coverage and charges vary, direct-only deals may be missed, and only the lender can approve a mortgage. Check the adviser’s FCA status, payment model and lender range, compare the full mortgage cost, and budget for the costs of buying and owning the home before deciding whether advice is right for you.
