Using a mortgage broker — rather than going direct to a lender — can access better rates, save time, and reduce the risk of rejection. Here’s how the main UK mortgage brokers compare.
Fee-Free vs Fee-Charging: Which Should You Use?
| Type | Cost to you | Best for |
|---|---|---|
| Fee-free, whole-of-market | £0 (broker earns lender commission) | Straightforward purchases, remortgages |
| Fee-charging, whole-of-market | £500–£1,500 | Complex cases, self-employed, bad credit |
| Tied broker | Varies | Usually not recommended — limited panel |
| Bank’s in-house adviser | Free | Only if you want that lender’s products |
For most buyers, a fee-free whole-of-market broker is the right starting point. If your case is complex, the fee charged by a specialist broker is often recovered many times over through a better rate or successful application.

Fee-Free Whole-of-Market Brokers
| Broker | How they work | Best for |
|---|---|---|

Fee-Charging Specialist Brokers
| Broker | Specialism | Typical fee |
|---|---|---|
| John Charcol | Complex cases, large loans, later life | £500–£995 |
| Coreco | Self-employed, London market, complex income | £500–£750 |
| Mortgage Advice Bureau (MAB) | Large national network, high-street style | Varies by adviser |
| SPF Private Finance | High-value properties, HNW clients | Percentage fee |
| The Mortgage Works (via brokers) | Buy-to-let specialist access | Through broker |
For self-employed borrowers, specialist brokers who understand complex income (dividends, retained profits, SIPP income) are significantly more effective than fee-free generalists.
For buy-to-let, using a broker with strong BTL lender relationships is important — stress test calculations vary widely between lenders.
How to Choose a Mortgage Broker
Step 1: Decide fee-free or specialist
Start with fee-free. Only pay a fee if your case is complex (self-employed, adverse credit, large loan, unusual property type).
Step 2: Confirm they’re whole-of-market
Ask directly: “Do you search the whole market?” A tied or panel-restricted broker will miss deals. FCA-authorised whole-of-market brokers are legally required to recommend the best product from their available market — but if that market is 10 lenders rather than 80+, that’s a problem.
Step 3: Verify FCA registration
All mortgage brokers must be authorised by the Financial Conduct Authority. Check the FCA Register before proceeding.
Step 4: Check reviews
| Review platform | What to look for |
|---|---|
| Trustpilot | Volume of reviews, response to complaints |
| Google Reviews | Local/branch-specific detail |
| VouchedFor | IFA and mortgage adviser-specific ratings |
Step 5: Understand how they’re paid
| Payment model | How it works |
|---|---|
| Commission only | Lender pays the broker on completion — you pay nothing |
| Fee + reduced commission | You pay a smaller fee; broker offsets against commission |
| Fee only | Rare; you pay directly, broker returns lender commission to you |
Mortgage Broker vs Going Direct — Cost Example
| Scenario | Direct to lender | Fee-free broker | Specialist broker (with fee) |
|---|---|---|---|
| Rate available | 4.35% | 4.19% | 4.05% |
| On £250,000, 25 years | £1,369/month | £1,345/month | £1,321/month |
| Monthly saving | — | £24 | £48 |
| 5-year saving | — | £1,440 | £2,880 |
| Broker cost | £0 | £0 | £750 |
| Net 5-year saving | — | £1,440 | £2,130 |
These are illustrative figures. Rate differences vary by market conditions and your individual profile.
When a Mortgage Broker Is Most Valuable
| Situation | Why a broker helps |
|---|---|
| First-time buyer | Navigates affordability, schemes, and lender criteria |
| Self-employed | Knows which lenders use net profit vs salary+dividends |
| Bad or thin credit | Prevents multiple hard searches destroying score |
| Unusual property | Ex-LA flat, short lease, non-standard construction — lenders vary |
| Buy-to-let | Stress test rates vary widely; broker finds best fit |
| Large loan (£500k+) | Private bank and specialist deals not available directly |
| Remortgage | Checks the whole market, not just current lender’s retention rate |
