What is the Five-Year Housing Land Supply — and why it matters to landowners

The short version

Every English local planning authority (LPA) is required to demonstrate, at any given point, that it has identified enough deliverable housing sites to meet five years of its housing requirement. This is the Five-Year Housing Land Supply — or 5-YHLS.

When an LPA cannot show that five-year supply, paragraph 11(d) of the National Planning Policy Framework kicks in — the so-called tilted balance. In practice, this dramatically tips planning appeals in favour of housing development, even on sites outside the settlement boundary.

Why this matters if you own land

If the council near your land drops below 5-YHLS, three things become true at once:

• Sites that would have been refused a year ago can suddenly be approved on appeal.
• Land outside settlement boundaries gains value almost overnight.
• Land promoters compete to secure agreements with landowners in the area.

This is the single most powerful planning lever in the English system — and it changes the conversation about your land entirely.

What we do at Upsurge

We actively track 5-YHLS positions across more than 25 English LPAs. When a council slips below 5 years, we engage with landowners in the affected area — promoting their sites on appeal, at our cost, using the tilted-balance argument.

Action for landowners

If you own land in a council whose 5-YHLS is under question — speak to us. Even if your land has been refused before, the planning calculus may now be entirely different.
