Should I use a mortgage broker?

This guide is written from an adviser-introduction perspective: use it to understand the issues to raise during a callback, not as a personalised recommendation.
For most UK borrowers, a broker is worth it — particularly if your case is anything other than vanilla employed with a clean credit file.
What a broker actually does
- Reviews your finances and explains realistic options.
- Compares lender criteria, not just headline rates.
- Gets an Agreement in Principle from the right lender.
- Packages your application and chases the lender.
- Handles queries from underwriting.
Whole-of-market vs panel
A whole-of-market broker can recommend from any UK lender. A panel-only broker is restricted to a list. For complex cases, whole-of-market matters.
How brokers are paid
- Lender commission — paid by the lender, doesn’t come off your loan.
- Client fee — flat fee (typically £300–£999) or a percentage.
- Both — most common model.
When to skip the broker
If you’re doing a simple product transfer with your existing lender and the rate is acceptable, you can usually do it online in 15 minutes.

Frequently asked questions
Does using a mortgage broker guarantee approval? +
No. A broker can help assess suitable lenders and package an application, but approval remains subject to lender criteria, affordability, credit checks, and valuation.
Do mortgage brokers charge fees? +
Some brokers charge a client fee, some are paid by the lender, and some use both methods. Any adviser fee should be explained before you decide whether to proceed.
