Are London Office Rents in 2026 Going Up or Down?

If you are trying to understand London office rents in 2026, the answer is not quite as simple as “up” or “down”.

At the very top end of the market, rents are high. Very high. Really high, in some cases.

If you are in private equity, a major financial business, or one of the big players looking for the very best new office space in the very best building, then the rent you pay may be eye-watering. But for some of these occupiers, rent does not seem to be the main concern. They want a particular building, in a particular location, with a particular image, and they will often pay whatever is necessary to get it.

For most companies, however, rent is not a badge of honour. It is a major overhead. It needs to be as low as possible for the type of space that actually works for the business.

And that is where the market becomes much more interesting.

Why London office rents in 2026 are telling two different stories

There are really two office markets running alongside each other.

The first is the prime market. This is the market for the newest, smartest, best-located buildings. The kind of space that helps attract staff, impress clients, support ESG targets and make the board feel that, yes, this is exactly where the business should be.

That market is still strong, and in some cases landlords are getting very high rents.

The second market is everything else. Good offices, perfectly decent offices, slightly older offices, fitted offices, offices in less fashionable locations, offices where the landlord would very much like the space let rather than sitting empty.

That market is much more of an open book for occupiers.

Hybrid working has changed the amount of space many businesses need. Some companies are taking less space. Some are delaying decisions. Some are still trying to work out what the office is actually for now.

Lower demand for space means:

• More space to let
• More choice for occupiers
• More pressure on landlords to be flexible

It is not complicated. Although, naturally, everyone in property will try to make it sound complicated.

Why the headline rent is only part of the story

When people ask whether London office rents in 2026 are going up or down, they are usually thinking about the rent per square foot.

That matters, of course. But it is not the whole picture.

A landlord may not want to reduce the headline rent. In fact, many landlords will fight quite hard to protect it, because once a lower rent has been agreed it can affect other deals, valuations and future expectations.

So instead of cutting the rent, they may offer something else.

That could include:

• A longer rent-free period
• A contribution towards the fit-out
• Works to improve the space
• More flexible lease terms
• A break clause
• A package that lowers the real cost of taking the office

This is why two deals with the same headline rent can be completely different in reality.

One may be expensive. The other may be a very good deal. The important question is not just “what is the rent?” The better question is “what is the total cost of occupying this office over the whole lease?”

That is where the real negotiation sits.

Are landlords becoming more flexible again?

Yes, in many cases they are.

Not because they have suddenly become generous souls. Let’s not get carried away.

Landlords will always try to hold out for the best rent and the best terms they can get. That is their job. If they think they can get more from another occupier, they will wait. If they believe their building is special, they will price it accordingly.

But if a space has been available for a while, if there are similar options nearby, or if the landlord knows the market is not exactly queueing round the block, there is usually a conversation to be had.

And sometimes a very useful conversation.

The flexibility may not always be obvious at the start. The first offer is rarely the best offer. The asking rent is rarely the full story. And the landlord’s opening position is not a sacred text.

The occupier who knows the market properly is in a much stronger position.

Why actual deal evidence matters for London office rents in 2026

This is the bit that really counts.

If you know the accurate details of rental deals that have ACTUALLY been done in the market, you can negotiate an office lease in a completely different way.

You need to know:

• What rent was agreed
• How long the rent-free period was
• Whether the landlord paid towards the fit-out
• Whether there was a break clause
• What other incentives were included
• How long the space had been empty
• What competing options were available

That kind of information is extremely powerful.

Without it, you are guessing. With it, you can challenge the rent, question the incentive package, compare options properly and avoid being impressed by a deal that only looks good on the surface.

This is especially important because London office rents in 2026 are not moving evenly across the board. Some landlords have the upper hand. Some do not. Some buildings are genuinely in demand. Some are simply being presented as if they are.

There is a difference.

What should occupiers do now?

The first thing is not to panic.

The second thing is not to believe every headline.

If you want the very best new space in the most in-demand part of London, then yes, you should expect the rent to be high. Possibly very high. Possibly “are you absolutely sure?” high.

But if you are like most businesses, and you want good office space at the best overall cost, there are still opportunities.

A sensible approach is to:

• Be open-minded about location
• Compare buildings properly
• Look at fitted options as well as traditional leases
• Ask what incentives are available
• Think about the full cost, not just the rent
• Never assume the landlord’s first proposal is the final deal

The market still rewards occupiers who know what they are doing.

Final thought

So, are London office rents in 2026 going up or down?

For the very best space, they are often still going up.

For much of the wider market, the answer is more useful than that. Landlords are still flexible, deals can still be negotiated, and occupiers who understand the real market can often achieve far better terms than the asking rent suggests.

There are no obvious signs that this window is closing.

For most companies, the opportunity is not about finding the cheapest office in London. It is about finding the right office, understanding what has actually been agreed elsewhere, and negotiating the full deal properly.

That is where the savings are.
