Q3 2026 rental market update: attracting reliable tenants in south west London
London’s rental market entered the third quarter of 2026 with high rents, slower price growth and continued competition for well-presented homes. The Office for National Statistics reported that the average London private rent reached £2,302 per month in June 2026, up 2.2% annually. London remained the most expensive English region but recorded the country’s slowest rental inflation. Across the UK, the average private rent was £1,388, 3.3% higher than a year earlier.
Zoopla's June 2026 rental report measures new lettings rather than the full stock of rented homes. It found that London was the only region where rental demand increased during the four weeks to 31 May, rising by 6%. Rental supply remained 20% to 30% below pre-pandemic levels across every region. For south west London landlords, demand remains supportive, but affordability limits how far asking rents can rise.
What the figures mean locally
Tenants in Putney, Earlsfield, Balham and surrounding areas compare listings carefully. An unrealistic asking rent can increase the time a property remains empty, while an accurate figure can generate stronger applications and reduce void periods.

Price correctly under the new advertising rules
Since 1 May 2026, written rental advertisements must include a specific asking rent. A landlord or agent cannot encourage or accept an offer above that figure. Our guide to the ban on rental bidding wars explains how the rule affects advertising and applicant negotiations. The broader reforms are covered in what the Renters' Rights Act means for Wandsworth landlords.
The initial valuation is therefore more important. Review comparable agreed rents, not only advertised prices, and consider the property’s size, condition, energy efficiency, furnishings, outdoor space and proximity to transport.
Attract tenants who are likely to stay
Reliable tenants are not identified by income alone. Apply referencing criteria consistently and avoid discrimination against applicants because they have children or receive benefits. Verify income and employment where appropriate, obtain previous-landlord references with consent and use a transparent affordability assessment.
Before a tenancy starts, landlords in England must complete Right to Rent checks for every adult who will use the property as their main home. Checks may use acceptable original documents, a registered Digital Verification Service or the Home Office online service where the applicant provides a share code.
Complete repairs before marketing, respond promptly to enquiries and give accurate information about bills and property condition. Tenants can now request permission to keep a pet, and landlords must consider each request rather than relying on a blanket refusal. The new pet rules for renters in Putney explains when refusal may still be reasonable.
Energy performance is also becoming more important. Domestic private rented homes are expected to reach EPC C or an equivalent standard by 1 October 2030 unless a valid exemption applies. Our guide to getting your buy-to-let ready for EPC C outlines sensible preparations.
