The new rules — is the increase even valid?
- Once in any 12 months. A second rise inside a year isn’t valid, full stop.
- Form 4A or nothing. Since 1 May 2026 (when tenancies became periodic under the Renters’ Rights Act), the statutory notice is the only way to raise rent — rent-review clauses in old contracts no longer operate, and a text, email or letter demanding more money is not a valid increase.
- At least 2 months’ notice before the new rent starts, and the start date must align with a rent period.
- Notice invalid on any of these counts? Keep paying the current rent — you don’t owe the new figure.
Also now illegal
Rental bidding — properties must be advertised at a price and landlords/agents
cannot accept offers above it. And
rent in advance is capped at one month, payable only after the tenancy is signed. “Offer your best rent” and “six months upfront” demands belong to the past — if you meet them, that’s a complaint to
your council’s private-renting team.
Challenging the figure — free, and de-risked
- Gather market evidence — screenshots of 3–5 genuinely similar local listings, plus photos of anything that drags your property below them (damp, ancient kitchen, no parking). (Doing a bigger area check? Our rent checker pulls local data.)
- Apply to the First-tier Tribunal (Property Chamber) before the date the new rent would start. It’s free and you don’t need a lawyer.
- The tribunal sets what the property would fairly rent for on the open market. Under the new Act it cannot set a rent higher than the landlord proposed and cannot backdate the increase to before the hearing — the two old deterrents are gone.
- Until it’s decided, you keep paying the existing rent.
And you’re protected
A rent rise is
not an eviction notice — and with
Section 21 abolished, a landlord can’t simply evict you for challenging. Retaliatory eviction routes are closed; possession now needs a real legal ground.

Got a Form 4A? Diary the start date — your free tribunal challenge must be in before it. Tonight: screenshot 3–5 comparable listings.
Got a rent demand that isn’t a Form 4A with 2 months’ notice? It’s not valid — keep paying the current rent and reply in writing saying so.
