When mortgage rates rise, it can feel like a major financial change.
For UK homeowners, first-time buyers and buy-to-let landlords, rising mortgage rates can affect monthly payments, affordability, remortgage options and long-term financial planning.
Whether you have a fixed rate mortgage, a variable rate mortgage, a residential mortgage or a buy-to-let mortgage, understanding how rising rates work can help you make better decisions.
This guide explains what happens if mortgage rates rise in the UK, how different mortgage types are affected, and what steps you can take to manage the impact.
Understanding Mortgage Rates in the UK
Mortgage rates are the interest rates charged on the money you borrow to buy a property.
The rate you pay affects how much your monthly mortgage payment will be. A higher mortgage rate usually means higher monthly repayments, while a lower rate can make borrowing more affordable.
Mortgage rates in the UK can be:
- Fixed rates: Your interest rate stays the same for a set period, often 2, 3 or 5 years.
- Variable rates: Your interest rate can change during the mortgage term.
- Tracker rates: Your rate usually follows the Bank of England base rate.
- Standard variable rates: Your lender’s own variable rate, which can move up or down.
Mortgage rates can also vary depending on whether the mortgage is:
- A residential mortgage for your own home
- A buy-to-let mortgage for a rental property
- A fixed rate mortgage
- A variable rate mortgage
Why Do Mortgage Rates Rise?
Mortgage rates often rise because of changes in the Bank of England base rate.
The Bank of England may increase the base rate to help control inflation and support economic stability. When inflation is high, interest rates may rise to reduce spending and borrowing.
When the base rate rises, it can become more expensive for lenders to borrow money. As a result, lenders may increase the mortgage rates they offer to customers.
However, not all mortgages are affected in the same way.
A fixed rate mortgage may not change immediately, while a variable rate mortgage may increase more quickly.
How Rising Mortgage Rates Affect Your Mortgage
Rising mortgage rates can affect people differently depending on their mortgage type, lender, loan amount and remaining mortgage term.
Here is a simple overview.
| Mortgage Type | What Happens if Rates Rise? | Main Risk |
|---|---|---|
| Fixed rate mortgage | Payments usually stay the same until the fixed deal ends | Payments may increase when you remortgage |
| Variable rate mortgage | Payments can increase during the mortgage term | Monthly costs may rise quickly |
| Tracker mortgage | Rate usually rises if the Bank of England base rate rises | Payments can change directly with the base rate |
| Buy-to-let mortgage | Mortgage costs may rise, reducing rental profit | Landlord income may be squeezed |
| Standard variable rate mortgage | Payments may increase if the lender raises its SVR | Usually less predictable and often more expensive |
Fixed Rate Mortgages: Temporary Protection
If you have a fixed rate mortgage, your monthly repayments usually stay the same until your fixed term ends.
This means that if mortgage rates rise while you are still within your fixed deal, your payments should not increase immediately.
Real-Life Example
Sarah locked in a 2.5% fixed rate mortgage for five years.
During that time, mortgage rates rose to 4%.
Because Sarah was on a fixed rate deal, her monthly payments stayed the same for those five years. This gave her peace of mind and helped her keep a steady household budget.
Key Point
Rising mortgage rates do not usually affect you straight away if you are on a fixed rate mortgage.
However, when your fixed term ends, you may need to remortgage or move onto your lender’s standard variable rate. If rates are higher at that time, your monthly repayments could increase.
Variable Rate Mortgages: Payments Could Increase
With a variable rate mortgage, your interest rate can change during the mortgage term.
This usually means your monthly mortgage payments can go up or down depending on market conditions, lender decisions or movements in the Bank of England base rate.
If mortgage rates rise, your monthly repayments may also rise.
Real-Life Example
John took a variable rate mortgage when the Bank of England base rate was 0.25%.
Later, the base rate increased to 1.25%.
As rates went up, John’s mortgage payments also increased, costing him an extra £150 per month.
Key Point
Variable rate mortgages can offer flexibility, but they also carry more uncertainty.
If rates rise, your mortgage payments may increase quickly. This makes budgeting carefully very important.
Buy-to-Let Mortgages: A Different Impact
Rising mortgage rates can also affect buy-to-let landlords.
Buy-to-let mortgages often have higher rates than residential mortgages. When mortgage rates rise, landlords may face higher monthly mortgage payments, which can reduce rental profits.
This is especially important for landlords with variable rate buy-to-let mortgages or landlords coming to the end of a fixed rate deal.
Real-Life Example
Emily is a buy-to-let landlord with a variable rate mortgage.
When mortgage rates increased, her monthly mortgage payments rose by £200.
This reduced her rental profit, so she reviewed her rental income, property expenses and mortgage options to help maintain profitability.
Key Point
Rising mortgage rates can squeeze rental income and reduce profit for landlords.
Buy-to-let landlords should plan ahead, review their mortgage deal regularly and consider how higher interest rates could affect their rental business.
Fixed Rate vs Variable Rate During Rising Mortgage Rates
Choosing between a fixed rate mortgage and a variable rate mortgage depends on your personal circumstances, budget and attitude to risk.
| Feature | Fixed Rate Mortgage | Variable Rate Mortgage |
|---|---|---|
| Monthly payments | Usually stay the same during the fixed term | Can go up or down |
| Budgeting | Easier to plan | Less predictable |
| Impact of rising rates | Delayed until fixed term ends | May be affected sooner |
| Flexibility | May have early repayment charges | May offer more flexibility |
| Best suited for | People who want payment stability | People comfortable with payment changes |
What Should You Do if Mortgage Rates Rise?
If mortgage rates rise, there are practical steps you can take to manage the impact.
1. Review Your Mortgage Deal
If your fixed rate mortgage is coming to an end, it is wise to start reviewing your options early.
You may want to consider:
- Remortgaging to a new deal
- Fixing your mortgage rate again
- Comparing rates from different lenders
- Checking your current lender’s product transfer options
- Reviewing whether your current mortgage still suits your circumstances
Starting early can give you more time to understand your options before your current deal ends.
2. Budget for Higher Payments
If you are on a variable rate mortgage or your fixed rate deal is ending soon, it is sensible to prepare for higher monthly payments.
You can do this by:
- Reviewing your monthly budget
- Checking how much your payment could increase
- Building an emergency savings cushion
- Reducing unnecessary monthly spending where possible
- Planning ahead before your mortgage deal ends
Even a small increase in mortgage rates can make a noticeable difference to monthly repayments.
3. Speak to a Mortgage Broker or Financial Adviser
Mortgage products can be complex, especially when interest rates are changing.
A mortgage broker can help you understand your options based on your income, credit profile, property type, deposit, mortgage balance and long-term plans.
This can be especially helpful if you have:
- A buy-to-let mortgage
- A variable rate mortgage
- A fixed rate mortgage ending soon
- Credit issues
- Self-employed income
- Changing affordability
- Multiple properties
Professional mortgage advice can help you make a more informed decision.
4. Consider Overpayment Options
Some mortgages allow overpayments without penalty, usually up to a certain limit each year.
If your budget allows, overpaying your mortgage can help reduce the amount you owe and may reduce future interest costs.
Before making overpayments, check:
- Whether your lender allows overpayments
- How much you can overpay without charges
- Whether early repayment charges apply
- Whether overpaying is suitable for your wider financial situation
Overpayments are not suitable for everyone, but they can be useful for some borrowers who want to reduce their mortgage balance faster.
Should You Fix or Go Variable?
Choosing between a fixed rate mortgage and a variable rate mortgage depends on your personal situation.
A fixed rate mortgage offers stability because your monthly payments stay the same during the fixed period. This can help with budgeting and provide peace of mind.
A variable rate mortgage may offer a lower rate at first, but it comes with uncertainty. If rates rise, your monthly repayments could increase.
When mortgage rates are rising, many borrowers prefer the security of a fixed rate mortgage. However, the right choice depends on your circumstances, risk tolerance and financial goals.
Quick Checklist: What to Review if Mortgage Rates Rise
Before making a decision, review the following:
- What type of mortgage do you currently have?
- When does your fixed rate deal end?
- Are you currently on a variable rate or standard variable rate?
- Could your monthly payments increase?
- Can your budget handle higher repayments?
- Are there better remortgage deals available?
- Would fixing your rate give you more stability?
- Do you need specialist advice for buy-to-let or affordability?
Final Thoughts: Rising Rates Are Manageable
Rising mortgage rates can increase monthly mortgage payments, affect affordability and reduce profits for buy-to-let landlords.
However, being informed and prepared can make the situation easier to manage.
Whether you have a fixed rate mortgage, variable rate mortgage, residential mortgage or buy-to-let mortgage, knowing your options and planning ahead can make a real difference.
