Two-Year or Five-Year Fixed? How to Choose When Rates Keep Moving

Another Thursday, another hold. The Bank of England kept base rate at 3.75% on 16 September – the fifth hold in a row – but don't let that fool you into thinking mortgage pricing has settled down. It hasn't. Swap rates have been climbing all month, several lenders have repriced more than once, and the average two-year fix now sits at 5.77%, with five-year deals close behind at 5.83%. If your current deal is ending in the next few months, or you're buying for the first time, you're probably wrestling with the same question nearly every client has put to me this week: two years or five?

Why a Steady Base Rate Doesn't Mean Steady Mortgage Rates

Headline figures can be misleading. Inflation rose to 3.1% in August, driven in large part by the ongoing conflict in the Middle East pushing up energy and fuel costs, and the MPC's vote was closer than the "held" headline suggests – three of the nine members actually wanted to raise rates to 4%. Markets read that split as a signal that further increases haven't been ruled out, and lenders price their fixed deals off where they expect rates to be over the life of the product, not just where they sit today. That's the real reason fixed rates have kept creeping up, in some cases more than once this month, even while base rate stood still.

The Case for a Two-Year Fix

A shorter fix buys you flexibility. If you think today's rate rise is a temporary reaction to the energy shock, and that inflation will cool back toward the Bank's 2% target once things settle, a two-year deal lets you come back to the market sooner and potentially remortgage onto something cheaper in 2028. It also suits anyone who expects a change in circumstances soon – a house move, a change of income, or paying off a chunk of the mortgage.

The downside is obvious: you're gambling that things will look better in two years, not worse. If rates are still elevated, or higher, when your deal ends, you'll be back through the whole process again, with another set of fees and another stress test.

The Case for a Five-Year Fix

A longer fix buys you certainty. You lock in a monthly payment and don't have to think about the mortgage market again until 2031, whatever the Bank does between now and then. For anyone who finds remortgaging stressful, or whose budget has no room for a payment shock, that peace of mind is worth something in its own right.

The trade-off is flexibility. Early repayment charges on five-year fixes are usually steeper, so if you need to move home, sell up, or switch products before the term ends, it can be an expensive change of mind. And if rates do fall back over the next couple of years, you won't benefit until the fix ends.

There's no universally right answer here. It depends on your numbers and your appetite for uncertainty, which is exactly why this isn't a decision to make from a rate comparison table alone.

Five Questions I Ask Before Recommending Either

1. Where realistically do you see yourself in five years – same house, bigger family, possible move?
2. How would an extra £150–£200 a month hit your budget if rates were higher at renewal?
3. Is there a real chance you'll need to break the deal early, for a move or otherwise?
4. What's the actual rate gap between the two-year and five-year options on the table? Sometimes it's 0.4%, sometimes it's barely noticeable.
5. What does the early repayment charge look like on each, in pounds, not just percentages?

What I'm Telling Clients This Week

With the next MPC decision not due until 5 November, and no clear steer on which way things go from here, I'm not telling anyone to panic into a five-year fix out of fear, or into a two-year fix out of hope. I'm telling them to look at the actual rate gap in front of them. When a five-year deal costs only a fraction more than a two-year one, the certainty is usually worth paying for. When the gap is wide, a shorter fix with a plan to review in good time can make more sense, provided your budget can stand a rise at renewal.

What I won't do is let a client choose blind. Run the numbers against your real monthly budget, not just the headline rate, and get whole-of-market advice rather than taking whatever your current lender offers you first. That's true in a calm market. It matters even more in one that's moving as much as this one.

If your deal is coming up for renewal, or you're weighing this decision for the first time, get in touch and we'll go through the actual figures together.

Kindest regards
