LONDON — Lower mortgage rates are sparking an uptick in the U.K. housing market, with home sales last month rising at the fastest pace since the post-lockdown boom, data showed.

Agreed home sales rose by 25% year-on-year in the four weeks to Sept. 22, marking the sharpest increase since the spring of 2021, when the market rebounded from the first Covid-19 lockdown, according to research published Thursday by property portal Zoopla.

Home buyer inquiries also increased by 26% annually over the same period, the data shows.

Shares of U.K. homebuilders Taylor Wimpey and Barratt Developments both rose 1.4% following the data release.

It comes as house prices ticked up at their fastest pace in almost two years in September, according to Nationwide, rising 3.2% year-on-year from 2.4% in August, when lenders began slashing borrowing costs in response to the Bank of England’s first interest rate cut in over four years.

Mortgages rates have now fallen to an average of 4.57% for a five-year fixed term, down from 5.53% last year, according to the latest data compiled by property portal Rightmove. Some rates for such products have dipped to 3.7%, well below the BoE’s 5% key rate.

“Lower mortgage rates are delivering a much-needed confidence boost to homeowners, many of whom have sat on the sidelines over the past two years,” said Richard Donnell, executive director at Zoopla, said in the report.

Mortgage approvals rose in August to the highest level in two years in years, the Bank of England said Monday.

Market watchers are now awaiting the BOE’s Nov. 7 meeting for further movement on borrowing costs, with Governor Andrew Bailey telling the Guardian Thursday that the Bank could be a “bit more aggressive” on rate cuts if inflation data continued to be good.

More such stock has been coming to the market, as landlords look to sell their buy-to-let properties ahead of anticipated tax hikes in the Labour government’s upcoming Oct 30. Autumn budget.

Donnell said that was likely to keep price growth in check over the coming months, as more owners of second properties come to the market.

“Speculation over possible tax changes in the Budget and the impact of previous tax changes are continuing to add to the growth in the number of homes for sale. We remain in a buyers market and greater choice of homes for sale will keep house price inflation in check into 2025,” he noted.

Finance Minister Rachel Reeves has suggested that she will likely have to raise taxes after discovering a £22 billion ($29 billion) “black hole” in the public finances.

Having ruled out changes to income tax, National Insurance social security payments and value-added tax (a sales levy), increases to capital gains tax and inheritance tax — both of which impact property sales — remain on the table.

Meanwhile, possible changes to the country’s controversial non-dom tax status is also spurring seller activity at the top end of the market, as ultra-wealthy U.K. residents weigh moves to other lower tax locations.
