What the August HomeLet Rental Index tells us about London's changing rental market - and what we're seeing across Shoreditch, the City Fringe and East London
Earlier this year, we were distinctly cautious about some of the rental growth being reported across London. The numbers were showing increases, but what we were seeing on the ground suggested something more complicated. The final run-up to the Renters' Rights Act prompted many landlords with long-standing, below-market tenancies to reset rents, either by agreeing increases with existing tenants or by recovering possession and reletting at prevailing market levels. Those increases were real, but they were not necessarily evidence of a market accelerating under its own steam.
By August, however, we think much of that distortion has now worked its way through the system. That makes this month's HomeLet Rental Index especially interesting because the headline data is beginning to look much more like the market we are actually experiencing.
HomeLet reports that average London rents have reached a new high of £2,238 pcm, up 1.4% in August and 5.1% year-on-year. That takes the capital above its previous October 2025 peak and puts London among the strongest rental regions in the country. The borough picture remains highly varied, with Wandsworth, Camden and the City, and Lewisham and Southwark all recording double-digit annual growth, while Tower Hamlets, Westminster and parts of outer London remain much flatter.
The headline is therefore undeniably positive, but what matters for landlords is not simply that rents are up. It is understanding what is driving those increases, where the market is genuinely strong, and where averages risk masking a very different local reality.
The statistics show one story, but on the ground the summer market feels stronger in a very specific way
August has continued almost exactly where July left off for us at base, with both months delivering record numbers of new tenancies agreed. What is particularly interesting is that those records have not been driven by an overwhelming avalanche of enquiries on every single property. Instead, we are seeing a more efficient market, where the applicants who do enquire tend to be serious, motivated and ready to move quickly when the right home appears.
That matters because raw enquiry volume is not always the best measure of demand. A landlord does not need fifty half-interested applicants. They need the right person, at the right rent, within the right timeframe. Our approach to marketing is deliberately designed around that principle. High-quality photography, accurate descriptions, strong floorplans and considered presentation mean that what applicants see online should closely match what they experience in person. That reduces wasted viewings and increases the likelihood that a genuine enquiry turns into a serious offer.
This summer, that conversion has been extremely strong. The vast majority of our listings are going under offer within seven to ten days, with only the occasional outlier taking longer. As a result, we are carrying some of the lowest summer stock levels we have seen for years. The market is not necessarily frantic in the way it was during the extraordinary post-pandemic period, but it is highly effective, and for landlords that is arguably more valuable.
London's record rent is real, but there is no such thing as one London market
The danger with any London-wide average is that it creates the impression of a single market moving in one direction. In reality, London is a patchwork of hundreds of micro-markets, often with very different conditions operating within a few streets of one another.
The August data illustrates this perfectly. Hackney and Newham are showing strong annual growth, while Tower Hamlets is broadly flat to slightly down. Camden and the City are materially higher, while Westminster has barely moved. That does not mean one area is "good" and another "bad". It means property type, specification, condition, transport access, local supply and tenant profile are all influencing performance in different ways.
Across our own portfolio, we are certainly seeing rents at all-time highs in many locations. Some properties are achieving substantial uplifts, particularly where the home is presented beautifully, priced correctly and supported by a strong management proposition. Others are showing clear signs that the local market has, at least for now, reached an affordability ceiling.
This is why we would strongly caution against taking a London-wide percentage and simply applying it to an individual tenancy. A 5.1% annual increase across the capital does not mean every landlord should expect, or attempt, a 5.1% increase on their own property. The real answer depends on the exact property, the exact location and what the market is telling us at that moment.
Pricing has become one of the most important skills an agent can offer
The ban on accepting offers above the advertised rent has changed the mechanics of pricing far more than many landlords initially appreciated. Previously, there was some room to launch slightly conservatively and allow strong demand to establish the final rental value. That safety net has gone. Today, the asking rent has to work from the outset, which makes the launch decision more important and, in some cases, more delicate.
We are seeing plenty of evidence across the portals of agents getting this wrong. Some properties are being launched too aggressively, apparently in the hope that tenants will negotiate down from an inflated figure. The difficulty with that strategy is that tenants can simply ignore the listing. Once a property has sat on the market for too long, the landlord risks losing momentum, accumulating void costs and eventually making one or more reductions that could have been avoided with more accurate pricing at the start.
Underpricing is equally problematic because there is no longer the same opportunity for the market to bid the rent upwards. The correct figure therefore sits in a much narrower band than before. Finding it requires more than historical comparables. It requires current knowledge of enquiry levels, applicant behaviour, local competition and how similar properties are actually converting.
It also requires understanding what the landlord wants from the process. Some owners are focused on maximum rental income and are comfortable allowing a little more time to test the upper end of the market. Others have tighter financial commitments and would rather secure an excellent tenant quickly than risk a costly void in pursuit of another £50 or £100 per month. Neither strategy is inherently right or wrong. The role of the agent is to understand the client's priorities and price accordingly.
That is where experience adds value. A private landlord managing one or two properties simply cannot have the same live market visibility as an agency handling multiple campaigns at the same time across the same area. Data matters, but so does judgement.
Presentation and resident experience are becoming part of the financial equation
Another thing that the headline rental data cannot capture is the extent to which presentation and service influence performance. We are seeing a very clear relationship between homes that are presented to a high standard and homes that generate the strongest levels of interest.
That does not just mean nice photography. It means the property itself being well maintained, clean, properly prepared and genuinely matching the marketing. Tenants are increasingly sophisticated and will quickly identify a gap between what was advertised and what they find at the viewing.
The agent's reputation matters too. Residents are spending a very substantial proportion of their income on housing, so they are increasingly interested in who will actually be managing their home. Reviews, communication standards and the experiences of previous tenants all contribute to the decision.
That is important for landlords because the agency relationship no longer sits neatly outside the property's value proposition. The quality of the agent can influence how attractive a tenancy feels to an applicant. In our experience, treating residents well and protecting landlord returns are not competing objectives. They are closely linked.
A well-managed property tends to retain better residents, generate fewer disputes, maintain its condition more effectively and perform more consistently over time. That has always been our philosophy at base, and the current market is making that connection increasingly obvious.
Tenants are still searching earlier, and that changes the marketing calendar
One of the most interesting behavioural shifts we have tracked throughout 2026 now feels firmly established. Historically, most London tenants began actively searching around four to six weeks before they intended to move. Today, we are routinely seeing applicants begin that process two to three months in advance.
Periodic tenancies have changed the way people plan. Tenants are no longer necessarily waiting until the final few weeks before making decisions. Instead, many are researching the market earlier, identifying what they want and timing their notice once they feel confident about their next move. The intention is often to minimise overlap while avoiding the pressure of a last-minute search.
The market itself has not disappeared or shifted seasons entirely. August and September remain incredibly important because London still has a huge student, graduate and young professional population moving around traditional academic and employment cycles. What has changed is the search window, and that means landlords and agents need to think differently about when a property should be brought to market.
The old assumption that there is little point advertising until four or five weeks before availability is becoming increasingly outdated. In many cases, the audience is already looking well before then.
The landlord market is changing just as quickly as the tenant market
Perhaps the biggest change we are experiencing at base is not on the tenant side at all. It is the number and type of landlords approaching us.
We have already taken on more new landlords in 2026 than in any full year since base launched, and two clear profiles are emerging. The first group is made up of experienced self-managing landlords who have simply reached the conclusion that the regulatory and technical burden is now too great to justify the risk. These are not landlords who have suddenly lost interest in their properties. Many have managed successfully for years. What has changed is the complexity of the environment around them.
As enforcement becomes more active and penalties more substantial, the economics of professional management start to look very different. Saving a management fee feels less compelling when weighed against the cost of inadvertently falling foul of a compliance requirement.
The second group is particularly interesting. These landlords generally understand compliance reasonably well already, but they are placing much greater value on the quality of care an agent provides. In many cases, the property is a former home rather than a faceless investment asset, so there is a strong emotional connection to how it is looked after.
Increasingly, these landlords are also paying close attention to how prospective agents treat tenants. They are reading reviews, looking at resident feedback and considering whether the agency's values align with their own. They understand that a poorly treated resident can quickly become a management problem, whereas a well-supported one is far more likely to look after the property, communicate constructively and stay longer.
We think that is a very healthy development for the sector. For too long, the industry has encouraged the idea that landlords and tenants sit on opposite sides of a transaction. In reality, the best outcomes usually come when both are treated fairly and professionally.
So, is London's rental market booming?
We would not use that word, but it is unquestionably performing strongly. The new HomeLet record of £2,238 pcm now feels much more reflective of genuine market conditions than some of the increases we saw earlier in the year, when RRA-driven tenancy resets were still feeding through the data.
Our own experience supports that view. July and August have both produced record numbers of new tenancies for base, most properties are moving to under offer within seven to ten days, and our available summer stock is unusually low.
What this is not, however, is a market where landlords can simply name their price. Tenants are informed, selective and increasingly organised. Pricing mistakes are punished quickly. Presentation matters, service matters and the reputation of the agent matters more than it once did.
For the best properties, presented properly, marketed intelligently and supported by excellent management, London remains an exceptionally strong rental market. For mediocre stock, unrealistic pricing or poor service, a 5.1% London-wide increase offers very little protection.
That is the real story behind this month's numbers.
What we'll be watching next
September has historically been one of the defining months of the London lettings year, so we will be watching closely to see whether the strong activity of July and August continues into autumn. We are particularly interested in whether the earlier tenant search cycle becomes permanently embedded, how the divergence between individual East London micro-markets develops and whether affordability starts to place a firmer ceiling on rental growth after this summer's record highs.
We will also be watching landlord behaviour. The number of owners approaching us for professional management suggests the Renters' Rights Act is not simply changing tenancy structures. It is changing what landlords expect from their agents and what they are prepared to pay for in terms of advice, compliance, resident care and risk management.
That may ultimately prove more important than whether the London average moves another one or two percentage points next month.
The statistics show one story, but on the ground the detail explains it. Right now, that detail tells us London's rental market is strong, but increasingly unforgiving of getting the fundamentals wrong.
