Builders register homes with NHBC before work is started on construction.
The amount of new homes registered in the third quarter of 2018 were 15% higher than the same period last year.
In the private sector 33,520 new homes were registered, up 16% year on-year, while 10,058 were registered in the affordable sector, an increase of 12%.
In London the number of homes has rocketed up 141% to 6,007, compared to 2,492 in the same period last year.
NHBC said the rise is due to a number of large developments being registered by housing associations and by inwards investors focused on the private rental sector.
Yorkshire and Humberside and the South West have also seen a dramatic increase of homes at 39% and 34% respectively.
Focus on innovation
NHBC chief executive Steve Wood said: “The upturn in registrations over recent months is good news for the industry and shows that there remains a strong demand for high quality new homes in many parts of the UK.
“The increase in London is welcome, although it has been boosted by a number of large-scale developments and has to be set against unusually low figures this time last year.
“On a broader front, the industry remains cautious in the short-run until the economic impact of Brexit is clearer.
“Attaining the government’s target of 300,000 new homes by the middle of the next decade will require a real focus on innovation, particularly the use of modern methods of construction, and on building skills and capacity in the workforce onsite, topics many builders are actively grappling with.”
