BTL Is Dead, Says Rathbones: Why Smart London Landlords Are Switching to Serviced Accommodation

A Wealth Management Giant Just Called Time on Buy-to-Let

When Rathbones, one of the UK's most respected wealth managers, publicly declares that buy-to-let investment is "no longer viable," it's worth paying attention. Their analysis, reported by The Negotiator, paints a sobering picture: despite UK gross yields hitting 6.9%, the reality for most London landlords is far less rosy once you factor in mortgage costs, Section 24 tax changes, regulatory burdens, and falling property values.

London flat values have dropped by roughly £19,000 on average, and many landlords who purchased after 2015 are now sitting on assets they can't sell without crystallising a painful loss. It's a brutal squeeze from both sides: yields that don't cover costs and capital values moving in the wrong direction.

But here's the thing. Selling at a loss isn't the only option. There's a proven operational model that can transform underperforming London stock into a genuinely high-yielding asset, and it doesn't require you to offload a single property.

The 6.9% Yield Headline Is a Mirage

Let's be honest about what that 6.9% gross yield figure actually means for London landlords. Gross yield is a number that looks great on paper and crumbles the moment you start subtracting real-world costs.

Once you account for mortgage interest (which you can no longer fully offset against tax), maintenance, void periods, letting agent fees, insurance, and the ever-growing compliance burden, many London BTL properties are delivering net yields of 2% to 3%. Some are even running at a loss.

The Rathbones analysis essentially confirms what thousands of London landlords already feel in their bank accounts: traditional BTL, especially in the capital, has become an exercise in subsidising tenants' housing while watching your equity erode.

So what's the alternative?

Serviced Accommodation: The Operational Model That Changes the Maths

Serviced accommodation (SA) is a strategy where your property is let on a short-term or mid-term basis to corporate travellers, relocating professionals, insurance placements, and project-based workers. Think of it as running a boutique hospitality business from your existing property.

Instead of locking into a single AST at £2,000 per month, the same one-bedroom flat in zones 1 to 3 can generate £3,500 to £5,500 per month when operated as a serviced apartment for corporate and mid-term guests.

Here's why the numbers work so differently.

Higher Nightly and Weekly Rates

Corporate clients and relocating professionals expect a furnished, well-maintained space with hotel-like amenities. They're also willing to pay a premium for flexibility, location, and quality. A well-positioned London flat can command £120 to £250 per night, or £1,800 to £3,500 per week on mid-term bookings.

Reduced Void Risk Through Diversified Demand

With traditional BTL, a single tenant departure can mean weeks or months of zero income. Serviced accommodation draws from multiple demand pools: corporate travel, insurance relocation, medical stays, film and TV production crews, and international professionals. When one segment softens, others typically pick up the slack.

Favourable Tax Treatment

This is a big one. Because serviced accommodation is classified as a trading business rather than a passive investment, it can qualify for more favourable tax treatment, including the ability to offset all costs against income. For higher-rate taxpayers crushed by Section 24, this is transformative.

What Landlords Need to Know Before Making the Switch

Serviced accommodation isn't a magic wand. It's a legitimate business that requires proper execution, and going in without understanding the details can lead to disappointing results.

Lease and Mortgage Compliance

Your mortgage lender needs to consent to short-term letting, and if your property is leasehold, the terms of the lease may restrict or prohibit stays under a certain length. Always check these before committing. Many lenders now offer specific consent for serviced accommodation, but it's not automatic.

The 90-Day Rule in London

Properties in Greater London are subject to a 90-day cap on short-term lets (under 90 consecutive nights) per calendar year, unless you obtain planning permission for a change of use. However, and this is crucial, bookings of 90 nights or longer are classified as mid-term lets and fall outside this restriction entirely. Corporate relocations and project-based stays frequently run for three to six months, making this a natural fit.

Operational Demands

Guest communications, cleaning turnovers, linen management, pricing optimisation, listing management, maintenance coordination: it's a lot. This is where most DIY operators hit a wall. The returns are there, but only if the operation runs smoothly. A single bad review or a pricing miscalculation during peak season can cost hundreds, even thousands, in lost revenue.

Furnishing and Setup Costs

You'll need to invest in quality furnishing, professional photography, and potentially some light refurbishment to meet the expectations of corporate guests. Budget £3,000 to £8,000 for a full setup on a typical London one or two-bedroom flat. The good news is that this investment typically pays for itself within the first two to three months of operation.

DIY vs. Professionally Managed: Where the Real Returns Live

Some landlords try to manage serviced accommodation themselves. And in theory, it's possible. In practice, the operational complexity is significant. You're essentially running a small hospitality business, and the gap between a well-managed SA operation and an amateur one shows up directly in revenue.

Professionally managed properties consistently outperform self-managed ones by 20% to 40% in net income. That's not a marketing claim. It comes down to dynamic pricing algorithms, optimised listing placement across multiple platforms, consistent five-star guest experiences, and the operational infrastructure to handle turnovers, maintenance, and guest issues without missing a beat.

This is exactly what Airhosts was built to do. As a London-based short-term let management company, Airhosts handles every aspect of the operation: from listing creation and pricing strategy to guest management, cleaning, and compliance. The landlord's role becomes genuinely passive while the property generates returns that make traditional BTL look like a savings account from the 1990s.

The Clearest Path Forward for London Landlords in 2026

Rathbones is right. The golden age of traditional buy-to-let is over. But that doesn't mean your London property has become a liability. It means the strategy needs to change.

Rather than selling at post-2015 lows and locking in a loss, repositioning your asset into professionally managed serviced accommodation lets you hold the property through the current downturn, generate significantly higher monthly income, and benefit from any future capital appreciation without the pain of today's depressed market.

London's corporate travel market is robust and growing. Companies are actively seeking serviced apartments as cost-effective, flexible alternatives to hotels. Insurance firms need temporary housing for displaced tenants. International professionals relocating to London want furnished, well-located apartments. The demand is there. The question is whether your property is positioned to capture it.
