UK house prices increased by 9.9% in the year to April 2014, up from 8% in the year to April, the ONS has claimed.

It says annual house price inflation in England was 10.4% – greater than Wales (3.3%), Scotland (4.8%) and Northern Ireland (2.6%).

The greatest rise was in London at 18.7% followed by the south-east at 8.9%.

Taking London and the south-east out of the equation, UK house prices increased by 6.3%.

The ONS says that the average London house price in April was £485,000 and in the south-east £320,000.

The figures drove the average UK house price to £260,000. However, removing London and the south-east, the average UK house price was £199,000.

The ONS is one of two official house price surveys and we are constantly told that they and the Land Registry work to two different methods, as if that made both all right. But the point is: they can’t both be right.

The Land Registry put the average house price across Wales and England at £172,069 for May – so there is a gap of nearly £90,000 between what it says and what the ONS says about the average house price.

The BBC was among media organisations reporting the ONS statistics without once referring to the very different Land Registry figures, let alone querying the huge gap.

ONS figures are close to Rightmove and the LSL Academetrics survey but a long way apart not only from Land Registry, but Nationwide and Halifax figures.

So who does the consumer trust? Which set of figures are journalists going to quote? Will the BBC ever mind the gap? And where is the agent going to get the meaningful comparables?

When the Land Registry monthly data is so out of sync with the ONS, surely it is time to shoot one of them.

Your guess is as good as mine. And that’s the problem.
