Can the Government Really Build 1.5 Million Homes?

Building 1.5 million homes in England by the end of this Parliament was one of the government's headline pledges — and one of the reasons for the sweeping planning reforms that followed, including the new "grey belt" category of green belt land. Northumberland has its own patch of green belt, running along the southern county boundary around Cramlington and Ponteland to keep those towns separate from Newcastle, so this isn't just a Westminster story. Here's where the numbers actually stand, and what it means if you're buying or selling here.

The target, and how far off it is

The pledge is 1.5 million net additional homes across England between July 2024 and the end of this Parliament — a rate of 300,000 a year, well above anything the country has managed in decades. Progress so far tells its own story: an estimated 342,100 net additional homes were delivered between 9 July 2024 and 15 March 2026, roughly 22.8% of the total target in a period that covers over a third of the Parliament. To close that gap, the government would need to deliver around 367,000 homes a year for the rest of this Parliament — more than double the recent run rate.

What's actually slowing delivery down

The most recent full-year figures are mixed. In the 2025–26 financial year, housing starts in England reached 130,170, up 15% on the year before — a genuine sign of momentum. But completions came in at 143,110, down from 152,040 the previous year and the lowest annual total since 2015–16. Homes started aren't homes finished, and the gap between the two is where the pledge is losing ground. Industry data points to a familiar cause: a structural shortage of skilled trades, with the sector short an estimated 225,000 workers by 2027 and more than seven in ten small building firms reporting a severe shortage of bricklayers, groundworkers and electricians. Forecasters expect that to push build costs up a further 3–5% in 2026 on top of everything already spent. There was a brighter signal in the most recent quarter — dwellings started between January and March 2026 were up 18% on the same quarter a year earlier — but even the government's own trajectory shows it would take over five and a half more years at the current pace to reach 1.5 million.

Grey belt: the reform meant to unlock land

Grey belt is the government's attempt to free up land without touching genuinely valued countryside — a sub-category of green belt covering scrubby, low-quality or previously developed sites, released for development under "golden rules" that set minimum levels of affordable housing. Councils have been set a new combined target of 370,000 homes a year to work towards, with Green Belt reviews identifying grey belt parcels expected to start emerging through 2026. But the policy's own scrutiny has been blunt about what it will actually deliver: a House of Lords Built Environment Committee inquiry concluded the grey belt approach is unlikely to have a significant impact on housebuilding nationally.

For most of Northumberland, the housing supply story isn't about green belt release at all — it's about a brand new Local Plan that's only just begun.

What this means if you're buying or selling in Northumberland

Northumberland's green belt is a narrow band protecting the gap between Cramlington, Ponteland and Darras Hall and the edge of Newcastle — not the kind of large-scale land bank that grey belt reform is really aimed at unlocking. The bigger local lever is Northumberland County Council's new Local Plan, which the council gave formal notice of in April 2026 and ran an initial consultation on through May and June — a process that will take years to translate into allocated sites and planning permissions, let alone completed homes. In practical terms, that means the national supply squeeze isn't closing any time soon, and Northumberland's own pipeline of new land is further behind than the grey belt headlines might suggest. If you're selling, that keeps demand for well-presented existing homes solid rather than diluted by a wave of new stock. If you're buying, it's a reason not to bank on a supply-led shift in your favour arriving on any predictable timeline — the property in front of you today is a safer basis for a decision than a planning pipeline that's still years from bearing fruit.
