House prices in Havering declined by 0.2 per cent in August despite witnessing a 1.5pc rise over the last 12 months.

The latest data from the Office of National Statistics (ONS) shows that the average property in the area sold for £373,241 – significantly higher than the UK average of £232,797.

The average homeowner in Havering will have seen their property jump in value by around £147,000 in the last five years.

Buyers who made their first step onto the property ladder in Havering in August spent an average of £316,999 – around £125,000 more than it would have cost them five years ago.

The data comes from the House Price Index, which the ONS compiles using house sale information from the Land Registry, and the equivalent bodies in Scotland and Northern Ireland.

Lawrence Bowles, associate director of the research team at estate agents Savills, said the uncertainty over the outcome of Brexit negotiations was fuelling a “tougher lending environment”.

He said: “House price growth in real terms is slowing, and inflation is growing at the rate we’ve been used to over the last few months. Buyers, sellers and lenders are all thinking maybe they should wait until they see the outcome of negotiations.

“Longer term, the issue we expect to see is affordability, as we expect the Bank of England base rate to be back above 2pc by 2021 – closer to historical levels, rather than the ultra-low rates we have seen in recent years.

“That, combined with stricter affordability stress tests, will make it more difficult for households to demonstrate that they are able to afford mortgages.

“But we would expect to see a bounce at some point, between finding out the Brexit outcome and the start of higher interest rates.”

Between July last year and June this year, the most recent 12 months for which sales volume data is available, 3,391 homes were sold in Havering, 6pc fewer than in the previous year.

The highest house prices in the country in July were found in Kensington and Chelsea, London, where properties sold for an average of £1.35 million.
