London’s rental market strengthened during the summer, with the latest official figures showing rents rising faster than they were earlier in the year. For landlords, that sounds like an invitation to increase asking prices. But the detail beneath the headline tells a more useful story: demand remains healthy, yet tenants are increasingly price-conscious and rental performance varies considerably between boroughs.
As the autumn lettings season approaches, the best strategy is not simply to ask for the highest possible rent. It is to set the right rent for the individual property, minimise vacancy and select a tenant who is likely to remain.
What the latest figures show
The Office for National Statistics reported on 19 August 2026 that the average London private rent reached £2,317 per month in July. That was 3.0% higher than a year earlier and up from annual growth of 2.2% in June. London rents also increased by 0.6% between June and July, their strongest annual growth rate since October 2025.
Rightmove’s latest Rental Price Tracker paints a similar picture for newly advertised homes. The average advertised London rent reached a record £2,791 per month in the second quarter of 2026, rising 2.0% during the quarter and 2.9% annually.
The two figures measure different parts of the market. ONS data cover rents across the wider stock of private tenancies, while Rightmove focuses on homes newly advertised to let. They should not be treated as competing valuations, but both indicate that rental values in the capital are edging upwards.
London is not one rental market
City-wide averages are useful for identifying direction, but they are not enough to value an individual property.
ONS figures for July show clear variations across areas in which Hampshire Heights operates. Average rents increased by 5.1% in Enfield and 3.6% in Barnet over the year. In Haringey, however, the annual increase was only 1.5%. Brent recorded growth of 2.0%, while rents in Westminster fell by 2.0%.
Even within the same borough, the result will depend on the street, property type, bedroom count, condition, energy efficiency, furnishing and access to transport. For example, the July ONS averages for Haringey ranged from £1,635 for a one-bedroom home to £3,178 for a property with four or more bedrooms.
This is why applying a blanket percentage increase across a portfolio can produce the wrong result. Each property needs its own evidence-based assessment.
Record rents do not mean unlimited tenant competition
Rightmove found that national rental supply was 1% lower than a year earlier in the second quarter of 2026. However, the average available home attracted approximately 10 enquiries, compared with 11 a year earlier and 22 at the peak of competition in 2022.
That is still above the pre-pandemic average of five enquiries per property, so demand remains firm. But tenants generally have more time to compare value than they did during the most pressured period of the market.
A well-presented home at a realistic price can still let quickly. An overpriced property may attract online views but fewer serious applicants, resulting in repeated reductions and avoidable vacancy.
The hidden cost of chasing the last £100
Suppose a property could let promptly at £2,300 per month, but the landlord markets it at £2,400 and waits an additional two weeks for a tenant. The extra £100 would produce £1,200 over a full year, but a two-week vacancy at the lower rent represents roughly £1,060 of lost income.
Once additional council tax, utilities, advertising, cleaning or finance costs are considered, most of the hoped-for increase may have disappeared. A longer delay can leave the landlord worse off altogether.
The calculation should therefore be based on annual net income rather than the headline monthly rent. Sometimes the strongest financial result comes from accepting a little less from a reliable tenant who moves in promptly and is likely to stay.
How landlords can prepare for the autumn market
Use recent local evidence. Compare genuinely similar homes that have let recently, rather than relying on the highest advertised property in the area. Asking prices do not always show the rent ultimately agreed.
Prepare before advertising. Complete repairs, safety checks, cleaning and photography before the property goes live. First impressions influence both viewing levels and the quality of applicants.
Make viewings accessible. Restricted appointment times can slow a letting and reduce competition. Where possible, arrange flexible access and respond quickly to enquiries.
Present the practical benefits. Storage, natural light, outdoor space, energy efficiency, transport links and good management can be more persuasive than decorative wording alone.
Assess the full application. The highest offer is not automatically the strongest tenancy. Affordability, references, intended length of occupation, communication and suitability for the property all matter.
Look after existing tenants. Retaining a responsible tenant can save remarketing costs, void periods and preparation expenses. Any rent discussion should take account of current market evidence and the value of a stable tenancy.
A stronger market still rewards good management
London rents are rising, but the market is more balanced than it was at the height of the post-pandemic shortage. This is positive for professional landlords: well-maintained properties remain in demand, while sensible pricing and responsive management can reduce voids and support long-term returns.
The important question is not simply, “How high can the rent go?” It is, “What price will produce the strongest overall result for this particular property?”
