What does a Mortgage Broker actually do?
Buying a home is exciting, but it can feel overwhelming — especially when you’re navigating the mortgage market. I’m Harvey Sandhu, your local mortgage adviser, and in this guide I’ll explain exactly what a mortgage broker actually does in a simple, practical way
If you just want the short answer, here it is. Most people use a mortgage broker to:
- Work out what they can realistically afford (not just what a calculator says)
- Find lenders most likely to approve them
- Avoid delays, refusals, and expensive mistakes
- Have someone manage the process from start to finish.
No obligation. No jargon. I’ll tell you early if something isn’t possible

How a Mortgage Broker Works for You
What does a mortgage broker do? My job is simple: help you make confident decisions and secure the right mortgage for your life, not just the right rate for today.
Buying a home is exciting, but it can also feel overwhelming. A mortgage is a huge financial commitment, and getting it wrong can be costly and stressful.
Here’s precisely how I work with every client:
How a mortgage broker assesses your financial & personal situation
Every mortgage starts with a detailed conversation. Not just numbers on a screen — it’s about your plans, your budget, your future.
During our initial conversation, we’ll talk about:
your income, savings, and current credit commitments
how long you plan to stay in the property
your job prospects, lifestyle, and future plans
Answers to the above questions will tell me how much flexibility you want in your mortgage, the type of mortgage you need, and how long it will last.
This is also known as a Confidential Fact Find, a tool for gathering all the answers lenders need to assess you properly.
How mortgage brokers calculate what you can afford to borrow (affordability explained)
Most of my clients always start by asking:
“How much can I borrow?”
But the more important question should be:
“How much can I comfortably afford?”
Now, regarding affordability, every lender has its own affordability model, and it’s based on the type of business they want.
Some love certain types of income; others don’t.
Some lend more to professionals, while others are stricter if you’re self-employed or on a visa.
So, I take your income, monthly commitments, and living costs… then run everything through multiple lenders’ affordability calculators to identify which lenders support your goals.
This helps us decide:
which lender could offer you the maximum mortgage amount
what the mortgage term could be
It’s a practical, real-world view of your affordability — not guesswork.
Mortgage costs explained: fees, charges & what to expect (UK buyers)
A critical point when it comes to mortgage rates: it’s not just about the mortgage rate. There are several additional costs that buyers often miss, and they play a part in the overall cost of the mortgage. Mortgage fees explained.
My job is to explain each one clearly so there are no surprises.
Below is a list of some typical fees that you could pay.
Mortgage product fees (sometimes called lender arrangement fees)
Mortgage product fees — often called lender arrangement fees — can range from £0 to £2,500+ depending on the lender and product.
You normally have two choices:
Pay the fee upfront:
- Avoids paying interest on it
Add the fee to your mortgage
- Reduces upfront cost but interest is charged on the fee for the full term, making it more expensive overall.
Some of the lowest rates come with high fees; some no-fee mortgages have higher rates.
I calculate the true cost over the full product period so you can see which option genuinely works out better.
Lender valuation fee (mandatory for the lender)
A lender valuation checks whether the property is suitable security for the loan.
Cost: £0 – £800 depending on the lender and value of the property
Many lenders now offer free valuations (up to a maximum property value).
This is not a structural inspection.
Private survey fees (optional, for your protection)
If you want a deeper understanding of the property’s condition, you can commission your own survey, also known as a RICS Property Survey.
Homebuyer Report: £350 – £900
Full Structural Survey: £600 – £1,500+
A private survey can reveal issues a basic lender valuation won’t identify, such as:
damp
movement
roof condition
timber decay
plumbing & electrical issues
Surveys are optional, but I always recommend them for older or unusual properties.
How mortgage brokers verify your documents (what lenders need)
Lenders require evidence for everything in your application. I guide you through exactly what’s needed:
payslips (employed)
tax calculations & tax overviews (self-employed)
bank statements showing income & expenditure
proof of deposit
identity checks
Missing or incorrect documents can delay processing and even result in declines (especially missing details of outstanding debts).
I make sure everything is accurate, complete, and packaged correctly.

How mortgage brokers find the right mortgage (true cost, not just headline rate)
I have access to more than 60 lenders, each offering over 40 products. This means there are thousands of different mortgage options available at any time.
Fortunately, I use advanced sourcing software that allows me to input your mortgage needs, identify the best product fit, and calculate the actual cost over your selected fixed period.
A low headline rate doesn’t always mean the cheapest option.
So, I compare the real cost once you include:
product fees
valuation fees
redemption fees
any applicable early-repayment charges
Two “5-year fixed” products can differ by thousands over the same period.
I show you:
which deals are genuinely cheapest over the full term
which products match your plans
which lenders are most likely to approve your case
The software does the calculations. My job is to review the results and match you with the right solution.
Not sure where to start?
Whether you’re buying your first home, moving, remortgaging, or dealing with more complex circumstances, a simple conversation can help clarify your options.
How brokers check lender criteria
The best mortgage rate in the world is irrelevant if the lender won’t approve your application.
All mortgage lenders have different criteria. Some are strict about:
how long you’ve been in your job
whether you are still in a probationary period
types of income (bonus, overtime, commission)
credit history
source of deposit
your employment type or visa category
I filter out lenders who won’t accept your circumstances, focus on those who will, and then package your application clearly and professionally — increasing the likelihood of approval.
How a mortgage broker handles your entire application (start to finish)
Mortgage applications involve a mountain of forms and communication with lenders, solicitors, and sometimes employers. Small mistakes can lead to big delays — or even losing the home.
I take care of the entire process, including:
completing the application
checking that all requested documents have been provided
communicating with lender underwriters
managing lender queries
giving you regular updates
You stay informed throughout the entire process. Visit 10 steps to buying a property for a look at the full process.
Mortgage funds are released, the purchase completes, and you receive your keys. Happy days!
What a mortgage broker does after your mortgage completes (ongoing support)
My support doesn’t stop when you move in. Mortgage products end, markets change, and life moves on.
I contact all clients 4–6 months before their product ends to:
review your circumstances financially & personally
review the market
compare new options
prevent you from falling onto a high standard variable rate
I stay with you throughout your mortgage journey — not just until completion.
Why using a mortgage broker helps you get the right mortgage
A good mortgage broker does far more than find the best rate.
I help you:
understand what you can safely afford
choose the right product based on true cost
meet lender criteria
navigate legal and valuation stages
avoid costly mistakes
stay supported long after completion
My goal is to make the mortgage journey clear, calm, and properly structured — so you can focus on the excitement of getting your new home.

Frequently Asked Questions About Mortgage Brokers
Is it worth using a mortgage broker in the UK?
Yes — for 99% of clients, using a mortgage broker is absolutely worth it.
A broker can access lenders and products not available directly to the public, compare thousands of options in one go, and identify lenders who will actually accept your application.
Brokers also help avoid declines, delays and costly mistakes — especially if you’re self-employed, on a visa, have complex income, or are buying your first home.
Do mortgage brokers get better rates than banks?
Often, yes. Many specialist lenders do not deal with the public directly and work only through brokers. These lenders sometimes offer lower rates, more flexible criteria, or lower overall product costs than high-street banks.
Even with high-street lenders, brokers may access broker-exclusive products that you would not see online or in a branch.
How do mortgage brokers get paid in the UK?
Most brokers receive a commission from the lender once your mortgage completes.
Some brokers may also charge a broker fee, depending on the complexity of your case.
At Berks & Bucks Finance, all fees are explained clearly upfront, and nothing is charged without your full understanding and agreement.
Is it better to go to a mortgage broker or straight to the bank?
Banks only offer their own products. A broker looks at many lenders and matches you with the one that:
- approves your circumstances
- offers the right product
- provides the best true cost over the full term
A good broker also manages documents, packaging, underwriting queries, and communication — something banks will not support you with.
Do I Need a Mortgage Broker or Should I Go Straight to the Bank?
Do mortgage brokers work with bad credit?
Yes — many specialist lenders are explicitly designed for clients with:
- missed payments
- CCJs
- Defaults
- IVAs
- low credit score
- thin credit history
- historic credit issues
And some of these lenders usually only work through brokers, not directly with the public.
I regularly deal with Bad credit Mortgages
Can a mortgage broker help if I’m self-employed or on a visa?
Absolutely 100 %. Self-employed income, contractor income, and visa-based applications often fall outside normal high-street criteria.
I regularly help clients with Skilled Worker, spousal, business, and other residency categories secure the right lender — even when high-street banks say no.
How long does a mortgage application take with a broker?
Typical timelines:
- Decision in Principle (DIP): 20 minutes
- Full application: 24 hours
- Valuation: 2–7 days
- Mortgage offer: 1–3 weeks, depending on the lender
A broker manages the entire process to minimise delays and keep the application moving.
Do mortgage brokers charge more than going direct?
No. Using a Mortgage broker does not make your mortgage more expensive. In many cases, using a broker saves you money because we compare:
- true cost
- product fees
- flexibility
- lender criteria
and help you avoid unsuitable products or hidden charges.
Will a mortgage broker do all the paperwork for me?
Yes — that’s a big part of the service.
I complete the full application, package your documents, speak with underwriters, check lender requirements, and manage everything through to offer and completion.
Can I ask my broker questions after completion?
Absolutely. My service continues long after you move in. I contact you 4–6 months before your deal ends to review your options and keep you off expensive variable rates.
