For a long time, London's rental market had a fairly simple reputation: put a decent property online at the right time and somebody would want it.
That isn't a strategy we'd be comfortable relying on now.
The rental market has changed, but not simply because of rents or supply. The rules around renting have changed too, and renters themselves have become much more informed about what they're looking for.
For landlords, that makes the quality of the decision increasingly important.
The asking price now really is the asking price
One of the most visible changes introduced on 1 May 2026 concerns rental bidding.
A rental advertisement must state a specific asking rent, and landlords and agents cannot encourage or accept an offer above that advertised amount.
That changes the conversation around pricing.
Putting a property on the market at an artificially low figure in the hope of generating competition is no longer an option.
The advertised rent needs to make sense from the beginning.
That means looking properly at the property itself, its condition, location, comparable homes and the people likely to rent it.
Rent increases need more thought as well
There is another reason why getting the starting position right matters.
Under the current system, rent generally cannot be increased during the first year of a new tenancy. After that, increases are limited to once a year and landlords must use the prescribed Form 4A process, giving at least two months' notice. A tenant can challenge an increase they believe exceeds the open-market rent at the First-tier Tribunal.
That doesn't mean landlords should automatically push the initial rent as high as possible.
Quite the opposite.
An ambitious rent that leaves a property empty for weeks can quickly become more expensive than a sensible rent that attracts the right tenant.
Renters are assessing management too
There's something else happening that isn't written into legislation.
People are getting better at researching properties.
Before arranging a viewing, a renter can look at the street, transport links, nearby shops, journey times and other properties available at a similar price.
During the viewing, the questions can be just as revealing.
Who manages the property?
How are repairs reported?
How quickly are problems normally dealt with?
What's included?
What happens if circumstances change?
A landlord might think they're letting four walls and a roof.
From the renter's side, they're choosing an experience they're going to live with every day.
Regulation is becoming part of property performance
This is perhaps the biggest shift.
Compliance used to be treated by some landlords as something sitting somewhere in the paperwork folder.
That's becoming increasingly difficult.
Since May, assured short hold tenancies have largely moved into the assured periodic system, Section 21 has gone for new notices, and the rules surrounding possession, rent, pets and rental discrimination have changed.
More changes are coming.
The government's implementation roadmap says the Private Rented Sector Database is due to begin a regional rollout from late 2026, with registration ultimately becoming mandatory for private landlords.
Good record-keeping therefore isn't just administration.
It's becoming part of running the property properly.
What wins now?
Probably the same things that should always have mattered.
A property that's priced sensibly.
A home that's ready when somebody moves in.
Clear paperwork.
Responsive maintenance.
Realistic expectations on both sides.
And somebody actually paying attention to what's changing.
London property will always move quickly.
But sometimes the smartest thing a landlord can do is stop trying to move faster than everybody else and make sure they're moving properly.
