Remortgage Searches Surge 40%: What It Means for Sellers

By Lisa Hayes · 7 October 2026

Mortgage searches jumped 23% in September to 1,912,458, according to Twenty7tec data reported by The Intermediary, and the biggest driver was homeowners remortgaging rather than buyers moving. Residential remortgage searches hit 860,951, up 40% on August and 44% on a year ago. If you are thinking of selling, that tells you something uncomfortable and useful: a lot of your neighbours have decided to stay put and fix their borrowing instead.

That is the real story behind the headline. Everyone loves a "market springs back to life" line, and a 23% monthly rise in searches certainly looks like one. Dig into it, though, and the lift is coming mostly from people protecting what they already own, not people taking a punt on a new home. I will explain why that matters, what it does to your sale, and when a remortgage is a smarter move than putting up a For Sale sign.

What did the September mortgage search figures actually show?

The data comes from Twenty7tec, a company that supplies software used by mortgage advisers, and was reported by The Intermediary on 6 October. Across September, advisers ran 1,912,458 mortgage searches. That is 23% higher than August and 15% higher than September 2025. On its face, that is a healthy bounce after a quiet summer.

The residential remortgage segment was the star. There were 860,951 residential remortgage searches in the month, a 40% rise on August and a 44% rise on a year earlier. Residential activity as a whole grew 22% month on month and 19% year on year.

Nathan Reilly, chief customer officer at Twenty7tec, summed it up: "Remortgaging is doing a huge amount of the work. Searches increased 40% in a month and are 44% higher than this time last year." He added that "when we see growth on that scale, it tells us that existing homeowners reviewing their borrowing are increasingly important to adviser workloads."

A caveat, because I do not want to claim more than the source says. A mortgage search is an adviser looking at the market on behalf of a client. It is not a completed mortgage, and it is certainly not a house sale. Searches are a signal of intent and activity, not of transactions. They tell us what people are thinking about. They do not tell us what they have done.

Why are so many homeowners remortgaging right now?

The Intermediary report ties the surge to pricing uncertainty. The Bank of England held Bank Rate at 3.75% in September, but three Monetary Policy Committee members voted for an increase. That split vote spooked lenders. Several major lenders raised their fixed mortgage rates, with some rises reaching 0.3%.

If you hold a deal that is about to end, that is a simple piece of arithmetic. Rates may go up, so you look now and lock in something before they do. That is what people do when they sense the direction of travel is against them. I covered the vote in more detail in our piece on Bank Rate being held at 3.75% with three votes for a rise, and the rates picture has not got friendlier since. Our look at mortgage rates hitting 6% sets out where fixed rates have got to.

There is a second reason, and it is a quieter one. After a summer when many people sat on their hands, there is a backlog of homeowners whose deals are ending and who have been putting the decision off. Autumn is when the diary pushes them. Reilly's remark about "existing homeowners reviewing their borrowing" fits that. This is people tidying up the fixed costs they can control in a market where they cannot control much else.

Is a remortgage surge good or bad news for the housing market?

Honestly, it is a bit of both. Good news: it suggests households are engaging with the market and advisers are busy. Bad news: it is a sign that people are choosing to stay in their existing homes rather than move. Every homeowner who locks in a new deal on the house they already own is, for now, a person who is not listing it.

That matters because a healthy housing market needs both sides. It needs sellers to list and buyers to buy, and chains are only as strong as the willingness of everyone in them to move. A remortgage boom is a sign of caution. When people feel confident, they move. When they feel nervous, they fix.

What does it mean for the number of homes on the market?

Here I will pull in the other data we have, because the remortgage figure does not stand alone. Zoopla's September House Price Index, published on 1 October, reports that the number of homes for sale is up 5% on a year ago while sales agreed are down 9%. So even with remortgagers staying put, there is no shortage of properties competing for the buyers who are active.

Put the two together and you get a market with plenty of stock, cautious buyers and a big slice of homeowners opting out of the moving game for now. That is not a recipe for bidding wars. It is a recipe for patient buyers who know they have choice.

One thing worth flagging: different sources measure mortgage rates differently. Zoopla's 5.2% is its estimate of a typical rate paid. The 6% figure in the headlines refers to average advertised five-year fixed rates reported by Moneyfacts. They are not the same thing, and I would rather you know that than assume one of us has got it wrong.

How are house prices holding up?

Prices are flat to slightly firmer, depending on whose index you read. Zoopla puts annual growth at 0.8% and the average UK home at £273,000, and its executive director Richard Donnell expects only about 0.5% growth by the end of the year. Lloyds, which publishes the index formerly known as the Halifax House Price Index, reported on 7 September that the average house price was £298,468 in August, down 0.2% on the month and 0.4% on the year, the first annual fall since November 2023.

Those numbers look contradictory at first glance. They are not. They use different data and methods, and when you are dealing with changes of a few tenths of a percent, the answer you get depends on how you count. The fair reading is that prices are going sideways. No collapse, no surge. A market in a holding pattern.

If you want the regional detail, Zoopla's data shows a clear north-south split. The North West is up 3.1% and Scotland 2.6%, while London is down 1.0% and the South East down 0.7%. I walked through that in our look at house price growth halving to 0.8%, and it is worth having in your head when you read any national headline. Your street matters more than the average.

Should you remortgage or sell?

This is the question the news raises, and the honest answer is that it depends on why you are thinking about moving in the first place. Let me take it in two halves.

When remortgaging makes more sense

If you like where you live, your circumstances are stable and the only reason you are looking at selling is that your mortgage deal is ending and the new rate frightens you, then remortgaging is probably the right call. Selling and buying involves stamp duty, agents' fees, legal costs and removal costs, and a new mortgage on a new purchase would probably be at the same higher rates anyway. Moving to dodge a rate is expensive and rarely works.

In that case, do what the 860,951 are doing: talk to a whole-of-market adviser, look at your options early, and lock in a deal before further lender increases. Most lenders let you secure a rate months ahead of your current deal ending, so there is rarely a reason to wait until the last minute.

When selling is the better route

If you have a reason to move that has nothing to do with rates, such as a job, a family change, a probate situation, a relationship ending or simply outgrowing the property, then a remortgage is just a way of putting off the decision. The market is slow, but it is not closed. Buyers who can get finance are still buying, and Zoopla says sellers achieving quick sales are doing so by pricing "realistically".

If you are in a hurry, or your property is the sort that struggles on the open market, a cash buyer can offer a faster and more certain route, typically completing in weeks rather than months. You will usually accept less than a full open-market price in exchange for certainty and speed, which is a trade only you can judge. Our how it works page explains how the process runs, and you can compare your options without committing to anything.

What does a remortgage rush mean for people who are selling?

There are three practical consequences for sellers, and none of them is dramatic.

First, you have less competition from other sellers than you might expect. If many would-be movers have decided to fix and wait, fewer homes come to market in the coming months. That is a small plus, though not one that overcomes the 5% rise in homes for sale that Zoopla is already reporting.

Second, you still face the same buyer problem. Buyers need mortgages, and mortgages cost more than they did. Zoopla says the typical mortgage rate has risen from about 4% at the start of the year to 5.2%, adding around £1,800 a year, or £150 a month, for a typical buyer. That caps what buyers can bid. It is one reason Zoopla describes them as "more selective" and "cautious".

Third, advisers are busy. If remortgages are taking up a lot of adviser time, as Reilly suggests, purchase buyers may find it harder to get quick appointments and quick decisions. I would not read too much into this on the numbers we have, because the source does not say it, but it is something to watch if your buyer seems to be stalling at the mortgage stage. Ask early how their application is progressing.

What should sellers do now?

• Price on evidence. Use recent sold prices for similar homes near you, not asking prices. Our free valuation tool is a quick way to get a first view.
• Ask about the buyer's finances before you accept an offer. A buyer with a mortgage in principle and a clear adviser is worth more than a slightly higher offer from someone who has not started.
• Keep your own mortgage in order. If your deal is ending while your home is on the market, ask your lender or adviser about portable products and early rate reservations so you are not exposed to a jump in your monthly payments.
• Check early repayment charges. If you are mid-deal and thinking of selling, find out what leaving costs, and whether the deal can be ported to a new home.
• Plan a longer timeline in slower regions. Zoopla's data shows London homes have only about a 30% chance of selling within three months, against around 75% in Scotland.
• Have a plan B. If your sale drags, know your alternatives, from a price reduction to a fast-sale route. Our sell house fast guide sets out what is available.

What is the outlook?

Do not expect a sudden recovery. Zoopla's Richard Donnell says borrowing costs are likely to stay high and expects house prices to rise by only around 0.5% by the end of the year, with buying power staying subdued. He still sees close to 1.1 million homes selling in 2026.

A remortgage surge does not change that outlook. If anything, it reinforces it. People are choosing to protect their existing position rather than to bet on a new one. That is rational behaviour in an uncertain market, and it is the same logic a seller should apply: do what makes your own finances safer, and be wary of anyone who tells you it is either the perfect time to sell or the worst.

The wider rate picture is the thing to watch. The Bank of England's next decisions and any further lender repricing will shape whether remortgaging stays this busy or whether it fades as people settle into new deals. Neither I nor anyone else can promise which way that goes, and I would treat anyone who does with suspicion.

The bottom line

The September mortgage figures look like a market waking up, and in a way they are. But the waking is mostly homeowners reviewing the deals they already have, not a rush of new movers. For sellers, that means plenty of competition for cautious buyers, and a need to price sensibly and move with eyes open.

If you are weighing up whether to stay or go, and want to see what a quick sale could look like in practice, you can start a free valuation and compare offers. There is no obligation, and it may simply confirm that fixing and staying put is the better move for you. Either answer is a good one if it is made with the facts.
