The UK mortgage market in 2026 is a bit of a mixed bag—and honestly, it’s no surprise people are feeling unsure about what to do next. On one side, there’s talk that things might settle down and rates could even come down slightly. But at the same time, we’ve seen fixed mortgage rates creeping up again recently, and things feel a bit unpredictable.
As an independent mortgage adviser, there’s one question that keeps coming up:
“Should I lock in a rate now, or wait and see if things improve?”
It’s a fair question—and not an easy one to answer.
In this article, I’ll walk you through both sides of the argument, looking at what’s happening in the UK right now and the global factors that are influencing mortgage rates behind the scenes.
Where Are UK Mortgage Rates Right Now?
The Bank of England base rate currently sits at 3.75%, following the Monetary Policy Committee meeting on 30 March 2026.
Mortgage rates, however, do not move in lockstep with the base rate. They are influenced by broader market expectations, particularly swap rates and government bond yields, meaning they can rise even when the base rate is unchanged.
Recent developments illustrate this clearly:
- Fixed mortgage rates have risen sharply in early 2026, with some five-year deals climbing from around 3.75% to over 4.7% within weeks.
- Lenders have withdrawn competitive products quickly, reflecting uncertainty and funding costs.
- A typical borrower re-fixing recently could pay around £100 more per month compared to just weeks earlier.
This volatility highlights a crucial point: timing matters more than ever.
Why Are Mortgage Rates Going Up Again?
Before deciding what to do, it really helps to understand what’s actually driving these changes.
a) Inflation Is Still Hanging Around
Inflation is the main thing that influences interest rates. When it’s high, central banks tend to push rates up to slow spending down.
Even though inflation in the UK has come down from its peak, it’s still higher than target—so there’s ongoing pressure keeping mortgage rates elevated.
b) What’s Happening Globally (Energy & Conflict)
World events play a big part too. Ongoing tensions in places like the Middle East have pushed up oil and gas prices, which feeds into inflation. When inflation expectations rise, lenders often respond by increasing fixed mortgage rates.
c) Bond Markets and Investor Confidence
Mortgage rates aren’t just about the Bank of England—they’re also tied to government bond yields (gilts). When these yields go up (often due to inflation worries or government borrowing), mortgage rates tend to follow, even if the base rate hasn’t changed.
d) Global Interest Rates Matter Too
The UK doesn’t exist in a bubble. What’s happening in the US and other major economies affects the cost of borrowing worldwide. So even if things look stable at home, global uncertainty can still push UK mortgage rates higher.
Why Some People Are Locking in a Rate Now
Given all that uncertainty, it’s no surprise many borrowers are deciding not to wait.
Peace of Mind in a Shaky Market
Fixing your rate now means you know exactly what you’ll be paying each month. When things are unpredictable, that kind of certainty can be really valuable.
Avoiding Sudden Rate Jumps
We’ve already seen how quickly rates can move. Waiting even a few weeks has ended up costing some borrowers more, so locking in now can protect you from short-term spikes.
Lenders Are Moving Quickly
When lenders start pulling deals or changing rates frequently, it’s usually a sign they expect things to get more expensive. Acting sooner rather than later can help you secure a better deal before it disappears.
Easier Budgeting
With the cost of living still a concern, having a fixed monthly payment makes it much easier to plan ahead. This is especially important if you’re a first-time buyer or already stretching your budget.
The Key Risks to Keep in Mind
Whether you decide to fix now or hold off, there are a few risks you can’t ignore.
Timing the Market Is Tough
Even professionals don’t get it right all the time. Trying to perfectly predict where rates are heading is, realistically, a bit of a gamble.
Affordability Could Change
If you wait and rates go up, you might find you can borrow less—or that the deal you wanted is no longer affordable.
Deals Can Disappear Quickly
In a fast-moving market, lenders can pull products with very little notice. Waiting might mean fewer options later.
Refixing Risk
If you go for a shorter fixed deal now, you could be back remortgaging in a couple of years—possibly at a worse time.
A More Balanced Approach
It doesn’t have to be a straight choice between fixing now or waiting it out. A lot of borrowers are taking a more flexible, middle-ground approach:
- Lock in a rate now, but keep the option to switch if better deals come along before completion
- Look at shorter fixed terms (like 2–3 years) so you’re not tied in for too long
- Focus on what feels comfortable for you financially, rather than trying to second-guess the market
So… What Should You Do?
Right now, the UK mortgage market is a bit unpredictable in the short term, even if things might settle down later on. You can however lock in a rate now and as long as the mortgage hasn't completed, if lower rates with that lender becomes available we can switch you to the lower rate.
- If you want certainty and peace of mind, fixing now probably makes sense
- If you’re happy to take a bit of a risk and can afford some flexibility, waiting might pay off—but there are no guarantees
