A Complete Guide to the Different Types of Mortgage in the UK

This guide talks about all of the these categories and other kinds of house loans. It also talks about how to pay back the loan and how to get the best rate. We also explore how lenders view borrowers and what factors are most important when choosing between the different types of mortgage and types of mortgage home loans available today. 

Types of Repayment Structures: How the Loan Will Be Paid Back 

Before you compare mortgage lenders or rates, you should know how the mortgage is paid back. The two types of home loans below, capital repayment and interest-only, change the balance over time. 

Capital Repayment Mortgage (Repayment) 

A capital repayment mortgage is the most common way for people in the UK to pay back a loan. Every month, you pay both the interest and a part of the balance that is still owed. The capital balance (the amount you owe) gets lower and lower each month, until it reaches zero. 

Why this is the most common way for people to borrow money for their homes: 

• At the end of the term, you own the property completely. 

• The debt goes down over time, so there is less risk in the long run. 

• This is a good option for people with steady incomes who plan to stay in their homes for a long time. 

Things to think about:  

• Monthly payments are higher than interest-only payments. 

• Not as easy for borrowers who don’t have a steady job. 

Many homebuyers, especially first-time buyers and families, prefer capital repayment mortgages for their simplicity and security. With each monthly payment, both interest and principal decrease, steadily moving you closer to full ownership and offering peace of mind. 

Interest-Only Mortgage 

An interest-only mortgage means that the monthly payments only pay off the interest accrued. At the end of the mortgage term, you must use a planned repayment strategy to pay off the full amount of the original mortgage balance.

Some common ways to pay back are: 

• Portfolios of investments 

• Lump sums for pensions 

• Selling the property 

• Profits from business or assets are some common ways to pay back 

Good for: 

• Some landlords who rent out their properties 

• Professionals with high incomes and well-organised financial plans 

• People who take out loans and think they will get a lot of money back in the future

Main risks: 

• If the way you chose to pay back your loan doesn’t work, you might have to sell or refinance. 

• There aren’t as many mortgage lenders who offer high loan-to-value interest-only loans. 

If you’ve got a clear plan for repaying the loan, an interest-only mortgage can work. You only pay the interest each month, so your payments stay low, but the debt itself doesn’t shrink. You’ll need a solid strategy – savings, investments, or selling the property — to clear the balance at the end. 

Many buy-to-let landlords still use interest-only mortgages to maximise monthly returns. It keeps costs down and cash flow strong, but it only works if you understand the numbers and stick to your plan. 

Different Types of Mortgages based on how they structure interest rates 

The next step after picking a repayment plan is to figure out how to set your interest rate. Some types of home loans offer more flexibility, protection and predictability than others. 

Fixed Rate Mortgage (Fixed Mortgage Loan) 

When you get a fixed-rate mortgage, your interest rate stays the same for a set number of years, which is usually 2, 3, 5, or 10 years. During the whole fixed period, your monthly payments stay the same

Pros: 

• Payments that stay the same every month. 

• Protection if interest rates increase. 

• Good for keeping your budget stable. 

Cons: 

• You might have to pay Early Repayment Charges (ERCs) during the fixed term if you wish to move or end the mortgage early. 

• Unless you refinance, most mortgages go back to the lender’s Standard Variable Rate (SVR) when the fixed period ends. SVR rates are normally very expensive as several interest points above any normal fixed or tracker rates. 

People who value certainty pick fixed-rate mortgages. You lock in one rate, one payment, for a set period – two, five, maybe even ten years which is becoming increasingly popular. It doesn’t move, no matter what the market does. 

Fixed mortgage loans suit people who want stability and don’t like risk. You pay the same every month, you can plan ahead, and rising interest rates won’t touch you. It’s simple, steady and predictable – which is exactly why many borrowers choose to fix. 

Tracker Rate Mortgage (Rate Tracker or Tracker Mortgage) 

A Tracker Rate Mortgage (also called a Rate Tracker or Tracker Mortgage) is based on the Bank of England’s “Base Rate” plus a set margin. Payments go up or down with the base rate. Some homeowners refer to this type of mortgage as a tracker mortgage or a rate tracker mortgage. 

Pros: 

• Payments might go down if interest rates go down. 

• Some tracker products offer more flexible to exit than fixed rate loans do. 

• Usually transparent – you always know exactly how your rate is calculated (Base Rate + margin). 

Cons: 

• Payments could go up quickly if the base rate goes up. 

• Some deals have a “collar” that keeps the rate from going below a certain level. 

• Less predictable – budgeting can be harder when your payments change with the market. 

If you’re comfortable with the idea that your monthly payments might rise or fall with the Bank of England’s base rate, a tracker mortgage could make real sense. It’s simple and transparent – your rate is the base rate plus a fixed margin, nothing hidden, nothing unexpected. When the base rate moves, your mortgage moves with it. 

Tracker mortgages appeal to people who like to see the rules clearly. You always know what’s driving your payments, and there’s no guessing what the lender might do next. It’s a good fit if you’re financially steady enough to handle some movement in your monthly costs and believe rates will hold or drift down. 

If you’d rather stay open to market changes than be tied to a fixed deal, a tracker gives you that freedom – with the understanding that flexibility comes with a bit of risk. 

Standard Variable Rate Mortgage (SVR) 

The Standard Variable Rate – or SVR – is what most mortgages move onto when the initial deal ends. Every lender sets their own rate, and it can change at any time. It’s not directly linked to the Bank of England’s base rate, though lenders often adjust it when the base rate moves. 

Pros:

• You’re free to leave anytime – no early repayment charges, no tie-ins.
• Useful as a short-term stop while you decide on your next mortgage deal.

Cons:

• Usually much higher than new fixed or tracker deals.
• The lender can change the rate whenever they choose, often without notice.
• Staying on SVR for too long almost always costs more than it should.

Most people don’t stay on the SVR for long. It’s a holding pattern, not a strategy. If you’ve slipped onto one, it’s usually time to remortgage – otherwise, you’re just paying more than you need to. 

Discounted Variable Rate Mortgage 

A discounted variable rate mortgage gives you a cut on the lender’s Standard Variable Rate (SVR) for a set time – usually two or three years. You’re paying the SVR, just with a discount. When the discount ends, the loan reverts to the full SVR. 

Pros:

• Lower starting payments make it cheaper at the beginning.
• If the lender drops their SVR, your rate drops too.
• Good for short-term buyers or anyone planning to remortgage soon.

Cons:

• Your payments rise if the lender increases their SVR.
• When the discount ends, your rate jumps — often by a lot.
• Discounts look attractive, but they’re only as good as the lender’s underlying rate.

A discounted mortgage can work if you want a cheaper entry point and can handle some risk. It’s not for comfort – it’s for people who watch the market and are ready to move when the deal runs out. 

Adjustable Rate Mortgage (ARM) 

An adjustable rate mortgage starts low, then moves. You get a fixed rate for a few years, then it shifts with the market. When rates go up, so do your payments. When they drop, you pay less. Simple as that. 

Pros:

• Cheaper at the start – that’s the hook.
• Good if you’ll sell or remortgage before the rate changes.
• Can save money short term if the market stays calm.

Cons:

• When the rate adjusts, your payments can jump overnight.
• Hard to plan ahead – you don’t know what you’ll owe later.
• If you stay too long, the low start gets wiped out by higher costs.

An adjustable rate home loan is for people who think in the short term – investors, movers, anyone not planning to sit still. It’s a gamble: low now, unknown later. 

Offset Mortgages 

An offset mortgage links your savings to your mortgage account. Your savings balance lowers the amount of the mortgage that you have to pay interest on, which lowers your interest costs. 

If you owe £180,000 and have £20,000 in linked savings, you only have to pay interest on £160,000.

Pros:

• Lowers interest costs without having to put money in a safe place.
• Can shorten the length of the mortgage.
• Very useful for people who pay a lot of taxes or work for themselves.

Cons:

• To work, it needs a steady savings balance.
• The interest rates on some fixed or tracker products may be a little higher than normal.

People who keep savings, run their own business, or hold cash in reserve often find offset mortgages extremely useful. Instead of earning small amounts of interest on your savings, you use that money to reduce the balance of your mortgage. You only pay interest on the difference. 

It gives your savings real purpose – every pound sitting in your offset account cuts down the interest you owe and can shorten the life of your loan. You can still access your money whenever you need it, but while it’s there, it works for you. 

Offset mortgages suit people who manage their finances closely and like flexibility. They’re especially useful for self-employed borrowers, landlords, and expats with income or savings in different accounts – anyone who wants their cash to pull double duty instead of sitting idle. 

Capped Rate Mortgage (Capped Mortgage Loan) 

A capped-rate mortgage is a variable mortgage with a built-in limit on how high your interest rate can go. The rate moves with the lender’s standard variable rate (SVR), but it can never rise above a set ceiling — the cap. 

If rates fall, your payments drop. If rates rise, you’re protected. It’s that simple. 

Pros:

• Fixed maximum rate – providing peace of mind for your worst-case scenario.
• If interest rates drop, you will still benefit.
• Flexibility compared to a fixed-rate mortgage.

Cons:

• The starting interest rate is usually higher than tracker or discounted mortgages.
• The cap might still be well above your current rate.
• Early Repayment Charges (ERCs) may apply if you switch or repay early.

A capped-rate mortgage suits people who don’t want to be locked into a fixed deal but still want a safety net if rates start climbing. The rate moves with the market, but there’s a ceiling – a cap – that it can’t go above. 

That cap is your line of defence. You get the freedom to benefit if rates fall, and the protection to stop things from getting out of hand if they rise. It’s a middle-ground choice for people who want flexibility without taking on the full risk of a tracker or variable deal. 

Capped mortgages work well for borrowers who like to stay in control but don’t want nasty surprises. 

Flexible Mortgage (Flexible Mortgage Loan)

A flexible mortgage lets you adjust repayments to suit your finances. You can overpay, underpay, or pause payments if allowed, and some lenders let you withdraw previous overpayments when needed. 

Pros:

• Save interest by overpaying
• Reduce or pause payments during financial challenges
• Access funds from earlier overpayments
• Useful for people with variable income

Cons:

• Interest rates may be higher
• Flexibility could encourage withdrawing repaid amounts
• Not all lenders offer full flexibility

Flexible mortgages are built for people whose income doesn’t always follow a straight line – freelancers, business owners, contractors, or anyone who wants more control over how they repay. You can overpay when money’s good, underpay when it’s tight, or even take a short payment break if your lender allows it. 

It’s a mortgage that bends with real life. Your payments move around your cash flow instead of the other way around. Over time, those extra payments can cut years off your term and save you serious interest. 

A flexible mortgage works for people who like to stay hands-on with their money. It gives freedom, but it demands discipline – because with that control comes responsibility. It’s the right choice if you want room to move without losing sight of the bigger financial picture. 

Buy to Let Mortgage (Buy to Let Mortgage Loan) 

A Buy to Let mortgage is for one thing – buying property to rent out. It’s not about a home for you. It’s about income, yield, and long-term growth. 

The lender looks at the rent the property can bring in, not just your salary. If the numbers work, the deal works. It’s that simple. 

BTL mortgages suit UK landlords expanding portfolios, expats holding property back home and foreign nationals who want a solid UK asset. 

Pros:

• Rent covers the mortgage and can create real profit.
• You own a physical, long-term investment that can rise in value.
• Property is something you can control — a real asset, not a line on a screen.
• A smart way for expats or overseas buyers to keep money in the UK market.

Cons:

• Lenders want bigger deposits – usually 25% or more for the best deals.
• Rates are higher than standard residential deals.
• You’ll face voids, repairs, tenants and tax.
• Tax and lending rules change often, especially for overseas owners.

Buy to Let only works if you treat it like a business. You’re not just buying property – you’re managing an investment. The numbers have to stack up: rent, costs, maintenance, tax, and time. 

Keep cash aside for the gaps – the empty months, the repairs, the things that never go to plan. Think long-term, not quick profit. Property grows in value slowly, but it rewards patience and discipline. 

For landlords, expats, and foreign nationals, Buy to Let is one of the clearest routes to owning income-producing UK property. But it’s not for the casual investor. It’s steady work – and the people who stay sharp, plan ahead, and run it properly are the ones who make it pay. 

Mortgage Categories Based on Purpose (Residential and Buy-to-Let) 

• Mortgages for First-Time Buyers

• Remortgaging

• Home Mover Mortgages

• Buy-to-Let Mortgages

• Self Employed Mortgages

Things to think about when choosing a type of mortgage 

There are many different types of mortgage loans – the mortgage with the lowest interest rate isn’t always the best kind. Think about the costs, valuations, ERCs and how flexible you can be in the long term.
