Should I Use a Mortgage Adviser or Go Direct to a Bank?

If you need a mortgage, you can approach a bank directly or speak to a mortgage adviser who can compare options from a broader range of lenders.

Both routes may be suitable, but they are not the same. The right choice can depend on how straightforward your circumstances are, how much of the market you want to explore and how much support you would like throughout the process.

This guide explains the differences between using a mortgage adviser and going directly to a bank, so you can make an informed decision about what feels right for you.

What is the difference between a mortgage adviser and a bank?

If you approach a bank directly, the bank will normally discuss mortgage products offered by that particular lender. It will assess your application using its own affordability calculations, lending criteria and available products.

A mortgage adviser can assess your circumstances and research suitable options from the range of lenders and products available to them. This may include high street banks, building societies and specialist lenders.

The main difference is therefore the range of options being considered and the support available while choosing and applying for a mortgage.

What happens if I go directly to a bank?

When you approach a bank, it will consider whether you meet its own lending criteria. If you are eligible, it can explain the mortgage products it currently offers and help you apply for one of them.

This route may feel convenient if you already bank there or have found a product you believe suits your circumstances.

However, being an existing customer does not necessarily mean that the bank will offer the most suitable mortgage for you. It also does not guarantee that your application will be accepted.

Different lenders can reach different decisions using the same information because their affordability calculations and lending policies are not identical.

What does a mortgage adviser do?

A mortgage adviser begins by understanding your circumstances, including your income, deposit, regular commitments, credit history, property plans and priorities.

They can then research the lenders and products available through their service and explain which options may be suitable.

A mortgage adviser can also help you:

Understand how much you may be able to borrow
Review the deposit you may need
Compare interest rates, fees and mortgage features
Understand different lenders’ criteria
Prepare the documents required for an application
Apply for an Agreement in Principle
Submit and manage the full mortgage application
Communicate with the lender and other parties involved

The support can continue from the initial conversation through to completion and beyond.

Why does mortgage lender criteria matter?

A mortgage is not assessed using the interest rate alone. Each lender has its own rules about the applicants, income and properties it will accept.

Criteria can vary in areas such as:

Employment and length of service
Self-employed income
Overtime, commission, bonuses and additional income
Credit history
Existing loans and credit commitments
Deposit source
Property type and construction
Maximum mortgage term and age limits

A lender offering an attractive rate may not be suitable if its criteria do not fit your circumstances.

A mortgage adviser can research criteria before submitting an application, helping you avoid approaching a lender that is unlikely to accept the case based on the information available.

Can a mortgage adviser access every mortgage?

Not necessarily. Mortgage advisers can have access to different lender panels and ranges of mortgage products.

Some advisers research a broad range of lenders, while others may work with a more limited panel. Some mortgage products are also only available when applying directly to a lender.

Your adviser should explain the range of mortgages they can consider and whether any limitations apply to their service.

Can a mortgage adviser get me a better interest rate?

A mortgage adviser may have access to intermediary mortgage products that are not available directly to the public. However, some lenders also offer direct-only products that an adviser cannot arrange.

This is why it is important to consider more than the headline interest rate.

The overall cost of a mortgage can also be affected by:

Arrangement or product fees
Valuation fees
Cashback incentives
The length of the initial deal
Early repayment charges
Overpayment allowances
The interest rate that applies after the initial deal ends

The lowest advertised rate is not automatically the most suitable or least expensive option for every borrower.

Does using a mortgage adviser improve my chance of being accepted?

No mortgage adviser can guarantee that an application will be accepted. The final decision always rests with the lender.

However, an adviser can help identify lenders whose criteria appear to suit your circumstances before an application is submitted.

They can also check your documents, explain any potential concerns and present the application clearly and accurately. This can reduce the risk of applying to a lender whose criteria are not suitable for the case.

How much does a mortgage adviser cost?

The cost of mortgage advice varies between firms. An adviser may charge the client a fee, receive a payment from the lender, or receive both.

Any fee should be explained clearly before you agree to proceed, including when it becomes payable and what service it covers.

It is helpful to consider the cost alongside the research, advice, application management and ongoing support being provided.

What support can a mortgage adviser provide?

Applying for a mortgage involves more than completing a form. Questions, document requests and unexpected issues can arise throughout the purchase or remortgage process.

A mortgage adviser can help by:

Explaining what the lender requires
Helping you prepare the application
Responding to questions from the lender or underwriter
Monitoring the application’s progress
Liaising with the estate agent, solicitor and surveyor where appropriate
Explaining the mortgage offer
Remaining available until completion

This can be particularly valuable if you are a first-time buyer, have a less straightforward income structure or simply want someone to guide you through each stage.

When might going directly to a bank be suitable?

Approaching a bank directly may suit someone who:

Already knows which lender and product they want
Has straightforward income and circumstances
Is comfortable researching mortgage options independently
Understands the lender’s criteria and application process
Is happy to manage the application without an adviser

It is still important to understand that the bank will normally discuss its own products rather than compare options from across the wider mortgage market.

When might a mortgage adviser be helpful?

Using a mortgage adviser may be particularly helpful if:

You are buying your first home
You are unsure how much you can borrow
Your income includes overtime, commission, bonuses or multiple jobs
You are self-employed
You have experienced previous credit difficulties
Your deposit is being gifted
You are buying an unusual property
You have been declined by a lender
You want help comparing different mortgage types and lenders
You would like support throughout the application and house-buying process

You do not need to wait until you have found a property before speaking to an adviser. An early conversation can help you understand your budget and prepare before you begin viewing homes.

Is mortgage advice regulated?

Mortgage advice should be provided by an appropriately authorised firm or an appointed representative of an authorised firm.

You can check a firm or adviser on the Financial Conduct Authority register.

Using a regulated mortgage adviser also means that certain standards and complaint procedures apply to the advice you receive.

How Cariad Mortgage Solutions can help

At Cariad Mortgage Solutions, we take a holistic approach to mortgage advice. We believe in putting people first and products last, looking beyond the mortgage itself to understand you, your circumstances and what you are hoping to achieve.

We will support you throughout the whole journey, from understanding what may be possible to collecting the keys to your new home.

We take the time to understand your income, deposit, existing commitments, credit history and future plans. We can then research suitable options from a broad range of lenders and explain the interest rates, fees, criteria and features in plain English.

Our support does not stop once you receive an Agreement in Principle. We can guide you during the house-hunting process, help you understand your property budget and support you when you are ready to make an offer.

Where appropriate, we can speak with the estate agent to help confirm your financial position and assist with the process of putting your offer forward.

Once your offer has been accepted, we can help you arrange a solicitor and surveyor. We will prepare and submit your mortgage application, deal with the lender and respond to questions from the underwriter.

We can also liaise with the estate agent, solicitor, surveyor and the other professionals involved, helping everyone remain informed as the purchase progresses.

We will remain by your side through the mortgage offer, exchange and completion. Our support continues beyond completion too, so you will still have a point of contact if you have questions or need help reviewing your mortgage in the future.

We are based at 142 Walter Road in Swansea and offer face-to-face, telephone and Microsoft Teams appointments to clients across South Wales and the UK.

There is no pressure, no jargon and no silly questions. We want you to feel informed, supported and confident, with someone in your corner throughout the journey.

Frequently asked questions

Is it better to use a mortgage adviser or a bank?

Neither option is automatically right for everyone. A bank will normally discuss its own mortgage products, while an adviser may be able to compare suitable options from a broader range of lenders. Your circumstances, confidence and preferred level of support can help determine which route suits you.

Can I speak to a mortgage adviser before viewing properties?

Yes. Speaking to an adviser early can help you understand how much you may be able to borrow, the deposit required and what documents you will need, giving you a clearer budget before you start making offers.

Does my own bank always offer the best deal?

Not necessarily. While banking with a lender might feel convenient, its affordability limits, criteria or product rates may not be the most suitable available for your specific circumstances.

Can a mortgage adviser help if I have already been declined?

Yes. A decline from one lender does not mean all lenders will say no. An adviser can assess the reasons behind the decision and look for lenders whose criteria are a better fit for your financial situation.
