The UK Government has confirmed it will not introduce rent controls, housing minister Matthew Pennycook told Parliament (PropertyWire, 17 April 2026), widening a policy divide with the Green Party just ahead of May's local elections.

What Pennycook Said and What It Means

Pennycook was direct: "The Government does not support the introduction of rent controls, which we believe could make life more difficult for renters." He cited evidence from Sweden, Germany, San Francisco and the recent Scottish experience to back the position. His conclusion was pointed - rent controls "typically benefit settled and better-off tenants more than those looking for a home or needing to move."

The Scottish experiment is the one to understand here. Scotland introduced rent cap legislation in 2022 and has since seen landlords exit the market at pace, reducing supply in the cities - Edinburgh and Glasgow particularly - where tenants need it most. The UK Government's position is that restricting rent levels discourages new supply entering the market, which makes the shortage worse over time.

For landlords, the immediate takeaway is that Westminster is not moving on this. But the story does not end at Westminster.

The Local Authority Angle Every HMO Landlord Should Watch

The Green Party's proposal is the one that matters at council level. Led by Zack Polanski, the Greens have made rent controls a central campaign issue and are specifically pushing to give local authorities powers to introduce their own caps. That means a council-by-council approach, not a national one.

That is significant for HMO (house in multiple occupation) landlords because room-by-room rents sit inside the broader rental market. A local cap would apply to HMO room rates just as it would to whole-property lets. The council requires what the council requires - and the rules vary wildly between authorities already on licensing, Article 4 directions (planning restrictions on converting properties to HMOs), and fee structures. Adding rent cap powers to that patchwork makes the picture more complex.

Rental price growth has stagnated for the first time since 2017 (PropertyWire, 17 April 2026), which may ease some political pressure around caps. Meanwhile, buy-to-let (BTL) lending has risen 18%, with remortgaging activity dominating the sector (PropertyWire, 17 April 2026). That suggests existing landlords are staying put rather than selling. But the political backdrop is shifting, particularly in urban councils where the Greens have real presence.

There is also internal Labour pressure. Dan Carden MP urged ministers to "look again at the evidence and start to consult" - meaning the Government's position, while firm today, is not unanimous within the governing party.

Kurt Mueller, Director of Corporate Affairs at Grainger, Britain's largest listed private landlord, backed the Government's stance, calling it "common sense" (Housing Today, via PropertyWire, April 2026).

What to Do Before May

Check your council's political composition. May's local elections could shift control in areas where the Greens are competitive. If your HMO sits in a marginal council, it is worth understanding what a local cap scenario would mean for your room rate strategy. You may wish to speak to your letting agent about current room rate data in your specific local authority area.

National rent controls are off the table for now. Local authority caps, under a different political configuration, are not.
