Using a mortgage broker isn’t compulsory, but for most buyers in the UK it’s one of the smarter decisions you can make. A broker searches the market for you, handles the paperwork, and can access deals that aren’t available directly to consumers. The question is how to find a good one.
Do you actually need a mortgage broker?
You can go directly to a lender — bank or building society — and apply for a mortgage without a broker. If you have a straightforward situation (standard employment, good credit history, buying a simple residential property), going direct is a perfectly reasonable option.
But brokers add real value when: your situation is more complex (self-employed, newly employed, variable income, credit blips), you want to compare a wide range of deals quickly, you want someone to handle the application process on your behalf, or you’re not sure which type of mortgage is right for you.
The mortgage market in the UK has thousands of products across dozens of lenders. A good broker cuts through that and finds what’s right for your specific situation.
Whole-of-market vs restricted
The first thing to check is whether a broker is “whole of market” or restricted to a panel of lenders. Whole-of-market means they can compare deals from all lenders (or very nearly). A restricted broker can only recommend products from their approved panel, which may not include the best deal for you.
Always ask: “Are you whole of market?” A good broker will tell you clearly.
How do they charge?
There are two main models. Fee-based brokers charge you a flat fee — typically £300–£750 — usually payable on completion. Commission-based brokers are paid by the lender when you complete, at no direct cost to you. Some brokers charge both.
Neither model is inherently better, but you should know which applies before you start. Fee-based brokers have an incentive to find the best deal for you; commission-based brokers have an incentive to recommend deals with higher commission. In practice most brokers are professional and regulated regardless, but it’s worth understanding the dynamic. Broker fees are just one part of the full cost of buying.
What qualifications should they have?
In the UK, all mortgage advisers must be qualified to at least CeMAP (Certificate in Mortgage Advice and Practice) level and be authorised by the Financial Conduct Authority (FCA). You can check any broker’s FCA registration on the Financial Services Register at register.fca.org.uk. Don’t skip this step.
Questions to ask before you commit
Before you agree to work with a broker, ask them: Are you whole of market? How do you charge, and when? How do you communicate — will I have a named contact? What’s your typical timeline from application to offer? Do you have experience with situations like mine?
A broker who can’t answer these questions clearly is a broker to avoid.
Red flags to watch for
Be wary of brokers who push you to decide quickly, who are vague about their fees, who can’t explain the mortgage products they’re recommending in plain English, or who seem more interested in upselling insurance products than finding you the right mortgage. Also avoid brokers who don’t carry out a proper fact-find — assessing your income, outgoings, credit history, and plans for the property — before making any recommendation.
Online brokers vs local advisers
Online-first brokers (large national services) are typically faster, often cheaper, and have good technology for tracking your application. Local independent advisers can offer more personal service and may have better knowledge of specific lenders’ quirks and underwriting criteria. Both can be excellent. The right choice depends on how much hand-holding you want and how complicated your situation is.
What to expect from the process
A good broker will start with a fact-find (around 30–60 minutes), then come back to you with a recommendation and a reason why it’s the right deal for your circumstances. They’ll then handle the application, liaise with the lender’s underwriting team, and keep you updated at each stage. Once you have an agreement in principle, the journey from initial conversation to formal mortgage offer typically takes 2–6 weeks depending on the lender.
Common questions
Do I need a mortgage broker to buy a house in the UK?
No, you can apply direct to a lender. But brokers add real value if your situation is complex (self-employed, variable income, credit blips), or if you want someone to compare the full market and handle the application for you.
What does 'whole of market' mean for a mortgage broker?
A whole-of-market broker can compare deals from all (or nearly all) lenders. A restricted broker is limited to a panel, which may not include the best deal for your situation. Always ask 'Are you whole of market?' before you start.
How do mortgage brokers charge?
Either a flat fee (typically £300–£750, usually payable on completion) or commission paid by the lender with no direct cost to you. Some charge both. Ask before you start so you understand the model.
