For UK landlords, reports of an autumn dip in tenant activity might be jarring, but a closer look at the latest data reveals that London’s private rental sector is not just surviving, but displaying remarkable resilience.
Despite a seasonal cooling as we approach the winter holidays, the fundamental metrics of the capital’s lettings market, from rental yields to tenant budgets, remain robust. Property investors in the Capital who are currently weighing up the viability of their portfolios can feel fairly confident that London buy-to-let is still a profitable endeavour.
While tenant enquiries have predictably dropped in the final quarter of 2025, the appetite for London property remains strong. However, with the impending Renters’ Rights Bill, is this a sustained forecast for buy-to-let landlords going forwards?
Rental returns remain robust
For the buy-to-let investor, the most critical metric is rental value. For the property investor, this is where the capital is typically a safe bet, and this year it continues to deliver. While there was a modest 3% monthly dip in pricing in October, the broader view paints a much more encouraging picture.
Rents have actually increased by 2% since the previous year across almost all London zones (with the exception of the North). This steady upward trajectory demonstrates the market’s capacity to shield landlord returns even during quieter trading periods.
Renters are currently committing an average of 99% of their stated budgets to secure accommodation. Interestingly, a significant 30% are still exceeding their stated spending limits to secure the right property. This willingness and ability to pay premiums for quality stock underlines the continued strength of the sector in the Capital.
Navigating the Renters’ Rights Act in 2026
With Phase 1 implementation of the Renters’ Rights Act confirmed for May 1, 2026, the window for preparation is narrowing. Smart investors should be using this period to actively restructure their portfolios to align with the new regulations.
Pricing, tenancy structure, and compliance are key areas to discuss with a lettings expert now. As the Abolition of Section 21 (No-Fault Evictions) means you can no longer terminate a tenancy without a specific legal reason. A lettings expert will help you make any necessary alterations to existing contracts, and may be able to make other useful recommendations.
While this is the main bone of contention for some landlords who fear that removing non-paying tenants will become more cumbersome, this change is also likely to lead to a reduction in tenant turnover.
However, the end of fixed term tenancies could have the opposite effect, particularly in areas dominated by fixed-term contracts, such as student HMOs and MUFBs. If you operate in this niche it’s a good idea to have a robust marketing plan and work with a specialist letting agent if you don’t already do so.
Landlords will need to work hard to forecast costs that have the potential to trigger rental price increases, given that only one increase per year will be permitted via the formal Section 13 notice procedure. Again, using an agent to help assess comparable local rents and evidence that any increases are in line with the market.
Strategies to protect profit margins
While the London investment property market has remained robust in 2025, many landlords, particularly those independently operating in the Capital, have exited the market due to the impending Renters’ Rights regulations. But with careful planning, profits should be maintainable, particularly in higher-value areas of the city.
Here are 4 tips for maintaining your current profit margins:
- Tighten tenant referencing criteria. Focus on affordability, long-term rental history, and guarantor backing. Since you cannot easily “test” a tenant with a 6-month break clause anymore, the initial selection is the most critical decision you will make.
- Instead of arbitrary increases, maintain a dossier of comparable local lettings (same size, condition, location). When serving a Section 13 notice for an annual increase, providing this evidence upfront can discourage frivolous tribunal challenges.
- Proactively upgrade the property to a high standard before a new tenant moves in. A premium property attracts premium, stable tenants who are less likely to default. Additionally, require Pet Damage Insurance (which the Act permits you to charge the tenant for) to mitigate risks associated with pets.
- Ensure your Landlord Insurance includes Rent Guarantee & Legal Expenses cover. With the shift to Section 8 evictions, legal costs for regaining possession could rise. Ensure your policy specifically covers the new possession grounds.
