The two-year mortgage puzzle: when to lock in before 2027
If you've been putting off a difficult conversation with your lender, 2027 might be the year it catches up with you. More than 2.3 million UK households are sitting on fixed-rate mortgages that expire next year, and when they do, many will face a sharp increase in monthly payments.
The timing is awkward. Property experts at Savills expect house prices to fall by 1.5% in 2027 itself, squeezed by mortgage rates that are unlikely to drop meaningfully until 2028 or beyond. That's the knock-on effect of prolonged geopolitical tension keeping interest rates higher than they would otherwise be, creating a peculiar squeeze for homeowners caught in the middle.
What's happening to mortgage rates right now
The Bank of England's base rate sits at 3.75%, but that's not what matters for most homeowners. What matters is what lenders charge for new fixed-rate deals. Today's average two-year fixed mortgage costs 6.58%, while a five-year fix averages 5.13%. That gap tells you something important: the market is betting rates won't fall quickly.
UK house prices haven't moved much recently either. Annual growth stands at just 0.9%, with the average property valued at £273,037. That sluggish pace is partly because potential buyers are sitting on their hands, uncertain whether to commit when they fear prices might dip further or when their own mortgage renewal looms.
The real impact of the 2.3 million renewal wall
Those 2.3 million households are facing something previous buyers didn't have to wrestle with. Many locked in sub-2% rates during the pandemic when borrowing was cheap. When their two or five-year deals end, they'll refinance at rates roughly double what they've been paying. For a typical household, that could mean hundreds of pounds extra each month.
The crunch point is psychological as much as financial. Someone who locked in at 1.5% might have budgeted carefully for a 2% increase when they signed up. A jump to 6% feels like a betrayal. Collectively, millions of these refinancing households will pull back spending elsewhere, creating ripples through the broader economy.
That's exactly why Savills expects downward pressure on prices through 2027. It's not because homes are suddenly worth less in any intrinsic sense. It's because fewer people have the appetite to buy when they're worried about their own mortgage costs, and some might feel forced to sell if they can't afford the new rate.
Should you act now or wait it out
The decision facing homeowners is whether to refinance early, before their current deal expires, or wait and hope rates fall. There's no universally correct answer, but the maths are worth checking.
If your fixed rate ends in 2027 and current deals are offering 6.5%, you could lock in now and pay a small early repayment charge to your current lender. That guarantees your rate for another two or five years and removes uncertainty from your budget. The downside: if rates genuinely do fall from 2028 onwards as Savills predicts, you'll regret locking in at today's prices.
Alternatively, you could wait until mid-to-late 2027 and hope the market has shifted. The risk is obvious: if it hasn't, you'll be forced to accept whatever rates are available at that moment. There's also a real possibility your lender won't accept your renewal application or will charge more because interest rate uncertainty increases their own risk.
A recovery pattern to watch
Savills expects house price growth to accelerate in the second half of 2028, reaching 3.5% for the full year. That recovery would be driven partly by first-time buyers returning to the market as affordability improves. The government's Your First Home scheme is part of that picture, making it slightly easier for younger buyers to scrape together deposits.
Over the next five years to 2031, property values are forecast to climb by 15.8% on average, equivalent to roughly £56,500 per home. That's assuming the geopolitical situation stabilises and the Bank of England feels comfortable cutting rates in line with inflation trends.
Northern England, Wales and Scotland are tipped for the strongest growth in percentage terms, reflecting their relative affordability compared to the South East.
What you can do now
If your mortgage renews in 2027, don't bury your head. Request an indicative rate from your lender or a mortgage broker six months in advance. Knowing your likely costs helps you plan. If the early repayment charge on your current deal is small relative to the rate saving, refinancing sooner might be worth it.
For those selling in 2026 or early 2027, accept that buyer appetite will be dampened by rate anxiety. Price realistically and be ready to move quickly when the right offer arrives.
And if you're thinking about buying, the pattern suggests waiting until late 2027 or 2028 might work in your favour, both on purchase prices and on your own mortgage options. The market will be quieter, but that's often when the best deals emerge.
