In the London lettings market, it’s not just how much landlords charge that matters, but when they list. Tenant demand, supply dynamics, and market behaviour shift throughout the year, and these cycles can push rents higher or lower depending on timing.
Understanding these seasonal rhythms helps landlords set competitive rents, reduce voids, and capture demand peaks.
Drivers of the summer lettings rush
The late summer period, roughly July through early September, is the busiest window for new tenancies in London. Several factors combine to create this seasonal surge in demand:
University and student cycles: Many students secure accommodation around the start of term, with searches intensifying in July and August.
Corporate relocations: Businesses often align relocations and graduate intakes with the academic calendar, bringing an influx of new renters in late summer.
Family moves: Families tend to relocate during school holidays to minimise disruption. This increases demand for family homes across London suburbs and commuter areas.
Tenancy expiries: Many tenancies naturally turn over in summer, which means more properties become available just as demand peaks, creating tighter competition among tenants.
Momentum and competition: High tenant activity drives urgency and competition. Landlords often achieve stronger rents in this period, as applicants move quickly to secure homes before September.
Evidence of seasonal rent patterns
Market data supports what many landlords already know anecdotally: summer is the peak letting season.
Rightmove’s Q1 2025 Rental Price Tracker reported that the average asking rent for new lets in London reached £2,712 pcm – up 0.5 % that quarter and continuing a multi-year upward trend.
Zoopla’s June 2025 Rental Market Report showed UK average rents rising to £1,301 pcm in July 2025, up from £1,287 in April – illustrating how rents often climb through spring and summer before stabilising later in the year.
Zoopla data also showed that rental supply rose by 17 % in the 12 months to April 2025, suggesting growing stock may start to moderate seasonal peaks in coming years.
These figures illustrate consistent summer strength in rental demand, even as broader affordability pressures begin to temper growth rates.
The shape of the annual rent cycle
Although precise month-by-month data for London is limited, the market typically follows this seasonal rhythm:
Based on observed trends and internal market analysis, rents in summer can often be 5–10 % higher than winter levels — though this varies by property type and location.
What this means for landlords
Seasonal demand is one of the most practical factors landlords can use to improve returns. Timing matters. Here’s how to take advantage:
Plan tenancy cycles carefully
Aim for contract renewals or new listings to coincide with July–August, when tenant competition is strongest.Price dynamically
In peak season, slightly higher asking rents are often achievable. In winter, a small price adjustment or added flexibility can help avoid voids.Minimise downtime
Use the summer window to pre-let upcoming vacancies. Forward-letting agreements can help keep income consistent.Monitor supply and demand
Local market shifts can temper seasonal effects. Keeping an eye on listing volumes and enquiry levels can guide realistic pricing.Maintain flexibility in off-peak months
In quieter periods, consider short-term lets or early renewals to bridge gaps until the next high-demand season.
Looking ahead
While the summer lettings surge remains a defining feature of the London market, we’re seeing gradual moderation as affordability pressures and increasing supply reshape dynamics. Nonetheless, the pattern remains clear: timing a tenancy start or renewal around late summer continues to offer the strongest chance of securing higher rents and shorter void periods.
At Letio, we help landlords plan around these cycles, using data, local knowledge, and transparent pricing to make every let as efficient as possible.
