Do I need a mortgage broker?

Quick answer

Most UK first-time buyers should use a broker.Not because mortgages are impossible without one — they aren’t — but because a whole-of-market broker can see the full lender market, match you to the lender most likely to accept you, find broker-only rates the public can’t see, and handle the paperwork.

Going direct can be fine if your case is clean and simple — a permanent job, two years of stable income, a healthy deposit, a standard property, and a bank with a strong existing-customer offer. Outside of that, the upside of a broker usually outweighs the fee (if any).

When a mortgage broker is genuinely worth it

Five situations where a broker meaningfully improves the outcome for most UK first-time buyers.

• Your situation is anything other than "standard"

  Self-employed, contract work, freelance, recent job change, gifted deposit, family loan, non-standard property (ex-council, above-shop, listed, unusual construction), small adverse credit history — any of these significantly cuts the number of lenders that will accept you, and brokers know who they are.

• You're stretching affordability

  If the amount you need to borrow is at or near the limit of what lenders will offer, different lenders use different income-multiple rules. A broker can find the one that maxes out for your specific profile, often £20,000–£40,000 above what the first bank you call would offer.

• You're a first-time buyer and unsure what's realistic

  An Agreement in Principle from a broker comes with a frank conversation about what you can realistically afford, what you'd qualify for, and what to fix first. Banks rarely give you that overview — they just tell you whether you fit their box or not.

• You're chasing the best rate

  Whole-of-market brokers see broker-only products that don't appear on price comparison sites or bank websites. Sometimes the difference is small; sometimes it's 0.3–0.5% lower, which on a £200K mortgage is roughly £30–£50/month cheaper.

• You don't have time to chase lenders yourself

  Researching, applying, chasing valuation, dealing with paperwork — the whole mortgage process eats time. A broker absorbs most of it. The fee (if any) often pays for itself in saved hours alone.

When going direct is fine

A broker isn’t always the better route. Three situations where going direct works well.

• You have a strong, simple application

  Permanent PAYE job with two years of stable income, clean credit history, 15–25% deposit, buying a standard freehold property well within your affordability — most major banks will lend to you on near-identical terms. Direct works fine.

• Your bank has a strong existing-customer offer

  Some banks offer materially better rates to existing customers with a long account history. If yours does, comparing it against broker-found products is worth the 30 minutes; if the bank wins, going direct is straightforward.

• You're remortgaging on the same property

  Switching products with your existing lender (a "product transfer") is usually paperwork-only — no new valuation, no full underwriting, no fees. A broker can help but the upside is smaller than on a purchase.

Even in these cases, a 30-minute conversation with a whole-of-market broker costs nothing (most are fee-free for an initial chat) and tells you whether the bank’s offer is genuinely competitive.

Whole-of-market vs restricted vs tied

Not all “brokers” have access to the same lenders. Three categories worth understanding before the first conversation.

Always ask outright before committing: “Are you whole-of-market, restricted, or tied?” Honest brokers answer plainly. Vague answers are a signal.

How brokers get paid

Four common fee structures. Get a written breakdown of both broker fee AND lender commission before instructing anyone.

• Fee-free

  Broker is paid only by the lender's commission (typically 0.3–0.4% of the loan). You pay nothing. Common for vanilla cases. Always confirm the broker is whole-of-market regardless of fee model — fee-free doesn't mean restricted.

• Fixed fee

  Usually £300–£600, sometimes refundable if the mortgage doesn't complete. Fair for moderate-complexity cases. Worth checking what's included — some firms charge separately for AIPs, ports, or re-applications.

• Percentage fee

  Usually 0.3–1% of the loan. £600–£2,000+ on a typical first-time buyer mortgage. Worth it for genuinely complex cases (heavy adverse credit, complex income, non-standard property) where the broker's work is substantial. Less defensible on a clean PAYE application.

• Fee + commission

  Broker charges you AND collects commission from the lender. Should mean cheaper fee for you because the lender side covers part of the cost. Ask for a written breakdown of both numbers.

Worked example: same buyer, three routes

Illustrative comparison for a fictional first-time buyer with a £40,000 income and a £15,000 deposit looking at a £230,000 property. Real outcomes vary widely; use the figures as shape-of-the-difference, not as a quote.

Illustrative only. Actual rates depend on the day, the lender, your credit profile and the specific product. The point isn’t the exact numbers — it’s that the borrowing ceiling and the rate can both move materially with the route you choose.

Questions to ask before instructing a broker

Nine questions worth asking on the first call. Honest, useful brokers welcome them; reluctant or evasive answers are useful signals.

• ?Are you whole-of-market, restricted, or tied to one lender?
• ?How are you paid — fee, commission, or both?
• ?If you charge a fee, is it refundable if the mortgage doesn't complete?
• ?Are there any extra charges for AIPs, second applications, or ports?
• ?What's your typical first-time buyer client and what lenders do you most often recommend?
• ?What's the realistic borrowing figure for someone with my exact profile?
• ?Have you actually placed a mortgage with my preferred lender in the last 3 months?
• ?What's the worst-case timeline from initial conversation to mortgage offer?
• ?Are you registered with the FCA? (Always confirm yes and check the FCA register yourself.)
