Mortgage Rates Are Rising Again: Should You Fix, Remortgage or Wait in 2026?

Mortgage rates are suddenly one of the biggest conversations in UK property again.

The Bank of England has raised Bank Rate to 4%, mortgage pricing has been moving upwards, and homeowners are rushing to investigate new deals.

In October alone, residential remortgage searches were 37% higher than a year earlier, while mortgage approvals for purchases continued to weaken.

For anyone approaching the end of a fixed-rate mortgage, the question is becoming urgent:

Should you fix now, wait for rates to fall, or reconsider your plans altogether?

Why Are Mortgage Rates Rising Again?

The Bank of England increased Bank Rate from 3.75% to 4% in November as inflationary pressures returned.

Mortgage lenders do not simply price fixed-rate deals directly from Bank Rate. They also look at financial-market expectations for where interest rates may be heading.

That means mortgage rates can start moving before the Bank itself changes rates.

The result is that borrowers who expected cheaper mortgages during 2026 are having to reassess their plans.

For landlords, the pressure is even greater. Average fixed buy-to-let mortgage rates had already reached around 5.79% at the start of October, according to Which?.

Why So Many People Are Remortgaging

The mortgage market is increasingly being driven by existing homeowners rather than people purchasing new properties.

More than 820,000 residential remortgage searches were recorded during October on Twenty7tec’s platform.

By comparison, house-purchase activity remains much more subdued.

This makes sense.

Someone already owning a home may have little choice about dealing with their mortgage when a fixed term ends.

A potential buyer, however, can wait.

That difference could continue to shape the housing market through the end of 2026 and into 2027.

Should You Fix Your Mortgage Now?

There is no universal answer.

But one principle is important:

Do not base a major financial decision entirely on the hope that rates will fall.

If a mortgage payment at today’s rate is affordable and gives you certainty, fixing can provide protection from further increases.

Waiting may work if rates eventually fall, but there is also a risk that they move higher.

Homeowners approaching the end of a deal should normally start investigating their options several months beforehand rather than allowing the mortgage to automatically move onto a potentially expensive standard variable rate.

What Does This Mean if You Are Thinking of Moving?

Higher mortgage rates change the move-or-improve calculation considerably.

Imagine you already have a £300,000 mortgage but need a larger house.

Moving could mean increasing that borrowing substantially while also paying:

• Stamp Duty
• Estate-agent fees
• Legal fees
• Surveys
• Removal costs
• Mortgage arrangement fees
• Repairs and improvements to the new home

Before moving, calculate the whole cost, not simply the difference between the two property prices.

Then compare that with what £50,000, £75,000 or £100,000 invested into your existing home could achieve.

A loft conversion, extension or internal redesign might solve the problem without requiring you to take on a significantly larger mortgage.

Is This Becoming a Buyers’ Market?

Potentially.

Higher mortgage costs are limiting what buyers can afford, while recent data shows house-purchase activity weakening.

That gives buyers more negotiating power.

A property advertised for £350,000 is worth only what someone is prepared and able to pay for it.

In a slower market, sellers who genuinely need to move may become increasingly willing to negotiate.

For cash buyers or purchasers with substantial deposits, this could create opportunities.

What About Property Investors?

The investment market is becoming particularly interesting.

October data showed buy-to-let purchase mortgage searches around 25% lower than a year earlier, while remortgage searches were slightly higher.

In simple terms, many landlords appear to be concentrating on refinancing existing property rather than buying more.

That is understandable.

Investors are dealing with:

• Higher borrowing costs
• Increased taxation
• Regulation
• Maintenance costs
• More demanding affordability calculations

But fewer investors buying can also create opportunity for those who still have capital available.

The Investment Strategy Is Changing

Traditional buy-to-let increasingly needs to produce a meaningful yield from day one.

Buying an expensive property producing a low rental return and relying mainly on future house-price growth is much harder to justify when financing is expensive.

The more interesting opportunities may increasingly be:

• Properties needing refurbishment
• Below-market purchases
• Mixed-use buildings
• Commercial property with flats above
• Properties with development potential
• Strong regional rental locations
• Assets where EPC or layout improvements increase value

The objective is increasingly to create value rather than simply wait for value to appear.

Could Landlord Sales Create Buying Opportunities?

This is something worth watching closely.

The Budget has already increased future tax pressure on personally held rental property.

Combine that with higher mortgage rates and some landlords may decide that certain properties are no longer worth keeping.

If more landlord properties reach the market, buyers could potentially acquire homes that have not been available for many years.

For investors, the key will be distinguishing between a genuinely discounted opportunity and a property being sold because the economics simply no longer work.

Five Questions to Ask Before Taking a New Mortgage

Before committing, ask yourself:

1. Can I comfortably afford the payment if rates stay high?

2. Am I buying the right property rather than simply the maximum I can borrow?

3. What happens when the fixed period ends?

4. Could improving my existing property be cheaper than moving?

5. If this is an investment, does the rent comfortably cover finance and other costs?

Those questions matter more today than chasing the lowest headline rate.

Final Thoughts

The mortgage market has changed remarkably quickly.

Remortgage activity is increasing, purchase activity is weaker and landlords are becoming more cautious.

That sounds negative.

But slower markets can also reward people who are prepared.

Homeowners may discover that improving their existing property makes more financial sense than taking on a much larger mortgage.

Buyers may gain greater negotiating power.

And investors with the right funding may find opportunities as other landlords retreat.

The key question in today’s property market is therefore no longer simply:

“Can I borrow the money?”

It is:

“Does borrowing this money create enough value to justify the cost?”

That is the calculation every homeowner, buyer and investor should be making as we head towards 2027.
