Bigger Mortgages Are Coming: What It Means for UK Sellers

By Lisa Hayes · 25 June 2026

Here is the short version, because I know you are busy and probably came here for an answer rather than a lecture. The Bank of England and the Financial Conduct Authority are quietly loosening the rules that decide how big a mortgage a buyer can take out relative to their income, and the key consultation closes on Wednesday 1 July 2026. In plain English, it means more buyers, and especially first-time buyers, could soon borrow more, which is a slow-burn boost to demand at exactly the moment the summer market has gone soft. If you are selling, this is good news on the horizon, but it is not a rescue boat arriving this week.

What has actually changed at the Bank of England?

Let me start with what is real, because the property world is full of headlines that turn out to be nothing. On 1 April 2026 the Bank of England published a consultation paper, snappily titled CP6/26 - High loan to income lending, setting out proposed changes to how the so-called LTI flow limit is applied. The consultation closes on 1 July 2026, and the regulators have set a backstop date of 31 December 2026 for the changes to take effect. So we are not talking about a vague aspiration. We are talking about a rule change with a date on it.

The headline proposal is this: the regulators want to remove the current 15% high-LTI flow limit that applies to each individual lender. According to the Bank of England, lenders should instead "have additional flexibility to determine their individual high LTI lending strategies, in line with their own risk appetite and business models," provided the aggregate flow across the whole market stays consistent with the 15% limit recommended by the Financial Policy Committee.

Read that twice, because the distinction is the whole story. Today, no single lender is supposed to let more than 15% of its new mortgages go to people borrowing more than 4.5 times their income without asking the regulator first. Under the new approach, one lender could choose to do far more than 15% of high-LTI lending, while another does less, as long as the market as a whole lands roughly where the Bank wants it. To keep the total in check, the PRA says it will publish the aggregate high-LTI figure on its website every quarter, and may at times ask individual firms to ease back towards 15%.

It sounds technical, and it is. But the practical effect on a real family trying to buy a real house is simple: the lenders most willing to stretch can now stretch a lot further for the borrowers who qualify.

What is a loan-to-income limit, and why does it even exist?

If your eyes glaze over at "LTI flow limit," you are not alone. So here is the human version.

After the 2008 financial crisis, regulators became understandably nervous about banks lending people enormous mortgages relative to what they earned. Borrow six or seven times your salary, and a small rise in interest rates or a wobble in your income can tip you into trouble fast. So in 2014 the Financial Policy Committee, the part of the Bank of England that watches for risks to the whole financial system, introduced a guardrail: no more than 15% of any lender's new residential mortgages should be at a loan-to-income ratio of 4.5 or above.

Crucially, that 15% cap was never meant to be a limit on you as an individual. It was a limit on the bank's book, designed to stop the entire system loading up on stretched borrowers at the same time. The trouble is that, in practice, it made lenders cautious. Once a bank got close to its 15% allowance, it would pull up the drawbridge on bigger loans, even for perfectly sensible buyers, to avoid breaching the rule. That is the friction the regulators are now trying to remove.

There is also a small-lender carve-out worth knowing about, because it shows the rule is aimed at the big players. The de minimis threshold stays unchanged: it only bites on firms doing more than £150 million of lending or 300 regulated mortgages over the relevant period. Your small regional building society was never the target, and still is not.

How much can buyers actually borrow now?

This is where the rule change meets the real world, and honestly it is where I would focus if I were you. Even before this consultation lands, lenders have been reading the direction of travel and loosening up. The traditional rule of thumb was that you could borrow around 4.5 times your income. That number has been quietly climbing.

Income multiple	Who it tends to apply to	Roughly what it buys a £60k household
4.5x (old default)	Standard affordability, most buyers	~£270,000 mortgage
5.5x (now common)	Mainstream borrowers meeting criteria	~£330,000 mortgage
6.0x - 6.5x	Higher earners, selected professional and first-time-buyer schemes	~£360,000 to £390,000 mortgage

The illustrative figures above are simplified for a household earning £60,000 between them, and every real case depends on credit, deposit, outgoings and the lender's own stress test. But the shape of it is the point. A jump from 4.5x to 5.5x is not loose change. On that same £60,000 income it is roughly £60,000 of extra borrowing capacity, which can be the difference between offering on your house and walking past it.

• 15%aggregate high-LTI flow limit the Bank wants to keep
• 4.5x → 5.5xtypical income multiple shift already underway
• 1 July 2026date the consultation closes
• £150msmall-lender exemption threshold (unchanged)

Why does this matter so much for the people most likely to buy your home? Because the buyers who get squeezed hardest by income multiples are the first-time buyers and second-steppers who form the foundation of almost every chain. Free them up to borrow a little more, and the whole chain above them breathes more easily. If you have ever lost a sale because the buyer at the bottom could not quite stretch to the asking price, you already understand the mechanism intuitively.

Why does a mortgage rule change matter if I'm selling, not buying?

It is a fair question, and I hear a version of it most weeks. You are selling, so why should you care what the Bank of England does to borrowers?

Because the price you can achieve is set by what your buyer can afford to pay, and what your buyer can afford to pay is set, more than almost anything else, by how much a bank will lend them. Mortgage availability is the hidden engine under house prices. When borrowing tightens, demand drains out of the market and prices soften, which is roughly the story of the last couple of years. When borrowing loosens, the opposite happens, usually with a lag.

So a rule change that lets buyers borrow more is, in effect, a rule change that gently lifts the ceiling on offers. It does not guarantee a higher price for your specific home. But it widens the pool of people who can credibly bid for it, and a deeper pool of buyers is exactly what you want when you are trying to sell your house quickly and with certainty. If you want a refresher on how today's prices are actually moving, our running guide to UK house prices in 2026 walks through the headline indices in plain English.

The regional picture: a genuinely two-speed market

Here is the part the national headlines tend to flatten. "UK house prices" is a fiction. There is no single market, there are dozens, and right now they are moving in opposite directions. Looser lending will not change that overnight, but it tends to help the more affordable regions most, because that is where income multiples bite hardest relative to prices.

Roughly speaking, according to recent Zoopla data, the more affordable North and the devolved nations are still rising at a decent clip, while large parts of southern England have stalled or slipped:

• North West ~+3.6%
• Scotland ~+3.0%
• Wales ~+2.4%
• UK average +1.5%
• South East ~flat

The figures above are approximate annual changes drawn from recent Zoopla commentary, and they shift month to month, so treat them as a picture rather than a promise. But the direction is consistent across the data providers. The Bank's lending change matters more in places like the North West, the North East, Scotland and Wales, where a modest bump in borrowing power converts directly into more buyers who can clear the asking price, and matters less in prime southern markets where affordability is stretched for reasons no income multiple can fix.

Index	Latest reading	Annual change	What it measures
Rightmove	£376,191 average asking price	-0.5% (asking)	New seller asking prices
Halifax	£298,806 average	+0.5%	Mortgage-approved sale prices
Nationwide	-0.6% month on month	+1.7%	Mortgage-approved sale prices
Zoopla	~£271,900 average	+1.5%	Achieved and agreed prices
ONS / Land Registry	~£271,900 average	+3.8%*	Completed sales (full market)

*That ONS figure of 3.8% looks punchy until you remember the context: the stamp duty thresholds changed in April 2025, which distorts the year-on-year comparison. It is a real number, but it flatters the underlying picture, which is why the survey-based indices are reading much cooler. Always read more than one index before you set your price.

How does this fit the wider 2026 market?

The lending change does not land in a vacuum. It arrives in a market that is, frankly, a bit grumpy. Let me set the scene honestly, because you deserve the full picture, not just the cheerful bits.

On the rates front, the Bank of England held its base rate at 3.75% on 18 June 2026, the fourth hold in a row, with the Monetary Policy Committee voting 7-2 to keep it there. UK inflation was sitting at 2.8%, a touch above target, and the conflict in the Middle East has kept policymakers cautious and borrowing costs higher than they were at the start of the year. The average two-year fixed mortgage rate was around 5.60% and the five-year fix around 5.58% in mid-June, although lenders including Nationwide, NatWest, Barclays, TSB and Santander have been trimming fixed rates back.

On the prices front, Rightmove reported that new seller asking prices fell 0.6% in June to £376,191, the biggest June drop in 14 years, leaving them around 0.5% below a year earlier. June usually brings a small rise, so a fall is telling. The culprits are familiar: a near-record number of homes on the market, buyers who are price-sensitive and spoilt for choice, and demand that was running about 10% lower than a year before. Savills, for what it is worth, expects average prices to end the year down around 2%, with the sharpest falls in the least affordable markets.

So the picture is a soft, oversupplied, buyer's market, cooled by stubborn mortgage rates, in which a meaningful loosening of lending rules is arriving like a slow tide turning. That combination is genuinely interesting. It is not a boom, but it is the first clear policy lever in a while pointed in sellers' favour.

The history: how did we get here?

It helps to see the arc, because it tells you whether this is a blip or a trend. The 15% high-LTI cap was born in 2014, in the long shadow of the financial crisis, when the worry was too much lending, not too little. For a decade it sat in the background doing its job quietly.

Then the ground shifted. By 2024 and 2025 the bigger worry had flipped: not reckless lending, but a generation of would-be buyers locked out of the market by a brutal combination of high prices, high rates and cautious affordability tests. In July 2025 the Financial Policy Committee formally recommended that the PRA and FCA change how the LTI limit is applied, to give lenders more room. CP6/26, published in April 2026, is the regulators turning that recommendation into actual rules. Alongside it, the FCA has been running a wider mortgage rule review, signalling that lenders already have flexibility within existing rules and need not apply rigid stress tests that block genuinely affordable loans.

Put the two together and you get a clear regulatory mood: after years of "computer says no," the dial is being turned, carefully, back towards "yes." That is the context every seller should file away.

What does it mean if you're selling right now?

Time for the honest balance sheet. I am not going to pretend this is all upside, because you would rightly stop trusting me. Here is the good and the awkward, side by side.

The trap I see sellers fall into is treating a hopeful headline as permission to hold out for a number the market will not pay today. Looser lending may help your buyer next spring. It does not help the buyer standing in your hallway this Saturday, who can still see the twelve other homes for sale on your street. Price for the market you are in, not the one you are hoping for.

What should I do now? A seller's action plan

Enough theory. Here is what I would actually do if this were my home on the market.

• Price to the data, not to the dream. Pull at least two or three indices and a couple of honest local agent appraisals, then position slightly ahead of the competition rather than the top of it. In an oversupplied market, the home that looks like fair value sells; the one chasing last year's peak gathers dust. Start with a realistic house valuation.
• Understand your true net figure. The headline offer is not what lands in your account. Run the numbers on fees, legals and timing so you can compare routes properly using our cost of selling guide.
• Check your buyer's mortgage, not just their enthusiasm. In a market where affordability is the binding constraint, a buyer with a firm agreement in principle at a sensible multiple is worth more than a higher bidder who is stretching. Ask the question early.
• Weigh certainty against the last few percent. If your priority is a guaranteed, chain-free completion to a deadline, a cash house buyer trades a slice of price for speed and security. Whether that trade is worth it depends entirely on your situation, and our guide on whether cash house buyers are a good idea lays out the honest pros and cons.
• Compare your routes before you commit. Open-market sale, assisted sale, auction and a direct cash sale all suit different goals. Line them up side by side on our compare options page before you sign anything.

What's the outlook for the rest of 2026?

If you want my read, and remember this is informed opinion rather than a crystal ball, here is roughly how I expect the next few months to play out. The summer stays soft. High supply and choosy buyers keep a lid on prices, and the holiday season does its usual job of slowing everything down. Sellers who price keenly keep selling; sellers who cling to ambitious numbers keep reducing.

Underneath that, two slow tailwinds keep building. Fixed mortgage rates drift lower as lenders compete and as markets price in eventual base-rate cuts, with the next decision due on 30 July 2026. And the lending rules loosen, first through the income multiples banks are already offering, then through the formal LTI changes due to be implemented by the end of the year. Neither is a fireworks display. Both are real, and both point the same way: towards buyers being able to borrow a bit more by the time the autumn market gets going.

My honest summary? The back half of 2026 looks better for sellers than the front half, but the improvement is a gentle slope, not a step change. The sellers who do best will be the ones who meet the market where it is now and let the tailwinds do their quiet work, rather than waiting on the sidelines for a boom that the data simply does not support.

The bottom line for homeowners

A dry-sounding consultation closing on 1 July is, underneath the jargon, one of the more meaningful pieces of good news sellers have had in a while. The Bank of England is loosening the rope on how much buyers can borrow, lenders have already started lending bigger multiples, and falling fixed rates are helping from the other side. None of it rescues an over-priced listing this week. All of it, together, makes the next twelve months a little friendlier to anyone trying to sell.
