My landlord is raising the rent: can they do that?

The message arrives: at renewal, the rent goes up. A percentage that sounds like a lot, with no more explanation than “that’s the market now”.

And you’re left with two questions at once: can they? and what do I do? They aren’t the same, and the second matters more than it looks.

First: not all increases are the same

There are three different situations and people mix them up:

A review inside the existing tenancy. The agreement is still running and a scheduled increase falls due. Here what governs is what your tenancy says, and any statutory limit that applies to it. It’s the most bounded of the three: there’s a mechanism, and it doesn’t depend on anyone’s mood.

Renewal. The fixed term ends and a new agreement is on the table. The room for manoeuvre is different, and depends on what protection your tenancy type gives you at that point.

A new tenancy. There’s no increase: there’s a new price, subject to whatever rules apply where you live.

Before arguing about anything, work out which of the three you’re in. Almost all the confusion comes from answering the wrong question.

Where the answer is

In two places, in this order:

1. Your tenancy agreement. Look for the rent review clause. It usually says how and when the rent can change. If it says something specific, that’s the first thing that governs.

2. The housing law in force where you live, on the date of your renewal. Here’s the trap: the rules on rent increases and notice have changed repeatedly in recent years in several jurisdictions, and what applied two years ago may not apply now. Any answer you find — in a forum, an article, an AI — may be describing a rule that’s been replaced, with total confidence.

So if the figure is high or the date is recent, check the date of what you’re reading. It’s the most expensive mistake and the easiest to make.

The questions that get you out of doubt

They work whether you’re asking an AI or a housing advice service:

• “Am I in a scheduled review, at renewal, or being offered a new tenancy?”
• “What exactly does the rent review clause in my agreement say?”
• “What limit or notice requirement applies to an increase on my renewal date?”
• “Does any local scheme or cap apply where my property is?”
• “If I don’t accept, what can the landlord do and with how much notice?”

The last one is the one almost nobody asks and the one that changes the conversation. Knowing what happens if you say no is what lets you answer without fear.

Careful with what an AI tells you

This is a textbook case for distrusting a single answer. We put it to several AIs with a specific case — a 12% increase at renewal — and they said contradictory things: some that the landlord couldn’t, another that they could.

None of them was lying. The answer depends on the date, the agreement and the area, and each one quietly assumed a different scenario.

That’s the value of seeing several at once: when they disagree, you know your case has no automatic answer and that you need to pin down the details. With only one you’d have kept whichever you happened to get, convinced.

We do it like this: several AIs answer separately and a fixed judge tells you where they agree, where they don’t, and with how much confidence. On a subject like this, low confidence isn’t a flaw in the answer — it is the answer.

And what you won’t find here

If this ends in a formal notice, a tribunal or a negotiation that decides where you live next year, this stops being information and becomes legal advice. That comes from a solicitor or a housing advice service, which in many places is free.

Our own jury doesn’t rule on binding legal matters: it refers. Not out of timidity — because the right answer depends on documents only someone holding them can assess.

What you do take from here is arriving at that conversation knowing which of the three situations you’re in, with the five questions ready. That isn’t nothing: it’s the difference between negotiating and accepting.
