How to Choose a Mortgage Broker

This guide provides general information and is not a substitute for personalised mortgage, tax or legal advice.

Written and reviewed by the Highhouse Money mortgage team · Last reviewed: 25 August 2026

A mortgage is one of the largest financial commitments most people make, and the broker you choose to help arrange it can materially affect the options you see, the advice you receive and how smoothly the process runs. Not all brokers work the same way, so it is worth understanding a few basics before you commit to one.

This guide covers what to check before instructing a broker, the difference between whole-of-market and panel arrangements, and how fee models typically work — so you can ask the right questions and make an informed choice.

Before you choose a broker, check:

They (and any individual advisor) appear on the FCA Financial Services Register with mortgage advice permissions
Whether they are whole-of-market or restricted to a panel of lenders
How they are paid — fee, commission, or a combination — and when any fee is due
Whether they have experience with your type of case, such as self-employment or adverse credit
How they communicate and how quickly they typically respond
What their complaints process is, should something go wrong
Whether they can support you through to completion, not just the initial recommendation

Start with the FCA Register

Before engaging any broker, check the Financial Conduct Authority's Financial Services Register. This confirms whether the firm is authorised to give mortgage advice and, where individual advisors are named, whether they personally hold the relevant permissions. It is a free, quick check and one of the most important steps you can take before sharing personal financial information with anyone.

If a firm or individual cannot be found on the register, or the permissions listed do not cover mortgage advice, treat that as a serious warning sign.

Whole-of-market versus panel brokers

A whole-of-market broker can access products from the full range of lenders operating in the market, or very close to it, giving you the broadest possible comparison. A panel (or tied) broker only offers products from a limited list of lenders it has commercial arrangements with, which can mean missing out on deals available elsewhere.

	Whole-of-market	Panel / tied
Lender access	Most or all of the market	A limited, pre-selected list
Comparison breadth	Wide	Narrower by design
Best for	Most borrowers wanting full choice	May suit specific arrangements, e.g. via a lender or estate agent

Ask any broker directly which category they fall into — the answer should be given plainly.

How broker fees work

There is no single industry-standard fee model. Some brokers charge the client directly, some rely entirely on the commission paid by the lender once a mortgage completes, and some use a combination of both. Neither model is inherently better — what matters is that the arrangement is transparent and you understand it before proceeding.

Highhouse Money is a whole-of-market broker. Where a fee applies to your case, we will confirm the amount clearly in advance, and it is only ever payable on completion of your mortgage — never on application or during the process.

Questions worth asking any broker

Are you whole-of-market, or restricted to a panel of lenders?
How are you paid, and when is any fee due?
Do you have experience with cases like mine?
Will the same person handle my case throughout, or will it be passed between people?
What is your process if my circumstances or the lender's decision change mid-application?
What happens if I don't proceed — are there any costs either way?

What a broker cannot do

No broker, however experienced, can guarantee a lender's decision — lending decisions rest with the lender's own underwriting against its current criteria. A good broker's value lies in matching your circumstances to lenders more likely to say yes, presenting your application clearly, and managing the process, not in overriding a lender's judgement.

If something goes wrong

Any FCA-authorised firm must have a process for handling complaints. If you raise a concern and remain unhappy with the outcome, you have the right to refer the matter to the Financial Ombudsman Service, which can investigate independently. This protection is another reason checking FCA authorisation at the outset matters.

Your home may be repossessed if you do not keep up repayments on your mortgage.

What lenders may assess

Lenders assess your application on its own merits — income, outgoings, credit history, deposit and the property — regardless of which broker submits it
A broker's role is to present your case clearly and match it to suitable lenders, not to influence the lender's underwriting decision

Every lender sets its own criteria, which change regularly. The points above are common themes, not a guarantee of how any individual lender will treat an application.

Frequently asked questions

Do I need a mortgage broker at all?

It is possible to approach lenders directly, but a broker can compare products across some or all of the market, handle the paperwork, and help present your application in the way a particular lender expects. Whether you need one depends on how complex your situation is and how comfortable you are researching the market yourself.

How do I check a broker is properly regulated?

Use the Financial Conduct Authority's Financial Services Register to check the firm and any individual advisor is authorised to give mortgage advice. Search by firm name or reference number and check the permissions listed match mortgage advice, not just an unrelated activity.

What's the difference between whole-of-market and panel brokers?

A whole-of-market broker can recommend from the full range of lenders in the market (or very close to it), while a panel or tied broker only offers products from a limited list of lenders they have arrangements with. Ask any broker directly which category they fall into before proceeding.

How are mortgage brokers usually paid?

Some brokers charge the client a fee, some are paid entirely through commission from the lender once a mortgage completes, and some combine both. There is no single standard model, so it is reasonable to ask upfront exactly how a broker is remunerated for your case.

Does Highhouse Money charge a fee?

Where a fee applies to your case, we will tell you the amount clearly before you proceed, and it is only ever payable on completion of your mortgage — never on application. In some cases no fee applies at all; we will confirm which applies to you upfront.

What should I ask a broker before instructing them?

Useful questions include: are you whole-of-market or restricted to a panel; how are you paid and when; can you help with my specific circumstances (for example, self-employment or adverse credit); and what happens if my application doesn't proceed. Their answers should be clear and given without pressure.

Can a broker guarantee I'll be accepted for a mortgage?

No broker can guarantee lending decisions, because these are made by the lender based on its own criteria and underwriting. A good broker can, however, help match your circumstances to lenders more likely to accept your application and flag issues before you apply.

What if I'm unhappy with the advice or service I received?

A regulated broker must have a complaints process, and if you remain unhappy after raising it with the firm, you can refer the matter to the Financial Ombudsman Service. Checking a firm is FCA-authorised in the first place means this route is available to you if needed.
