BTL Company Formations Are Falling: Why Smart Landlords Are Pivoting to Serviced Accommodation

For the first time since 2008, the number of new buy-to-let company formations has fallen. According to recent data reported by Mortgage Solutions, the incorporation boom that defined the last decade of UK property investment may have finally peaked. Even more telling, over half of new incorporations are now fresh purchases rather than portfolio transfers, which suggests that existing landlords who wanted to move properties into a company structure have largely already done so.

So where does that leave you if you're a London landlord sitting inside a limited company that was built for traditional buy-to-let? The short answer: it's time to rethink what your company structure is actually for.

The Incorporation Wave Has Crested

Let's rewind briefly. The rush to incorporate started after the Section 24 tax changes were announced in 2015. Mortgage interest relief for individual landlords was gradually stripped away, and incorporating into a limited company became the go-to strategy for protecting yields. Corporation tax allowed landlords to offset mortgage interest in full, and retained profits could be reinvested without an immediate personal tax hit.

It was a sensible move at the time. But now, in late 2026, the landscape looks very different. Corporation tax sits at 25%. Dividend tax rates have crept upward. Extracting profits from a company structure has become more complex and, for many landlords, less rewarding than the spreadsheets originally promised. The landlords who incorporated early captured the biggest advantages. Those arriving late to the party are finding diminishing returns.

The decline in new formations is the market's way of saying: incorporation alone doesn't solve the yield problem anymore.

The Real Issue: Your Company Structure Is Optimised for the Wrong Strategy

Here's what rarely gets discussed. Most landlords who incorporated did so with a traditional assured shorthold tenancy (AST) model in mind. Long-term lets, single tenants or families, monthly rent collected through an agent. The company structure was a tax wrapper, not a business strategy.

But AST yields in London have been under sustained pressure. Rising mortgage costs, tighter regulations, selective licensing, EPC requirements, and the looming Renters' Rights Bill have all eaten into margins. A typical AST in Zone 2 or Zone 3 might yield somewhere between 3.5% and 4.5% gross. After mortgage payments, management fees, maintenance, void periods, and corporation tax, the net return can feel underwhelming.

The company structure itself isn't the problem. The strategy running inside it is.

Serviced Accommodation: The Strategy Your Ltd Company Was Actually Made For

If you already own property through a limited company, you're actually in an excellent position to pivot toward serviced accommodation and corporate lets. This is where the real value of a company structure shows up in 2026.

Serviced accommodation means furnishing your property to a high standard and letting it on a short-term or medium-term basis, typically through platforms like Airbnb, Booking.com, and direct corporate booking channels. Instead of one tenant paying £2,000 per month, you might generate £4,000 to £6,000 per month from the same property through nightly and weekly stays.

Why the Numbers Work Better

London remains one of the strongest short-term rental markets in Europe. Business travel, tourism, relocation stays, and medical tourism all create consistent demand across the calendar year. A well-managed one-bedroom flat in a central London borough can realistically achieve 75% to 85% occupancy at nightly rates that dramatically outperform AST rents.

Within a limited company, the financials become even more attractive. Furnished holiday let or serviced accommodation expenses, including furniture, professional cleaning, platform fees, linen, toiletries, and professional management, are all fully deductible business costs. Your company is genuinely operating as a hospitality business rather than simply holding a rental asset.

What You Need to Know Before Making the Switch

Pivoting to serviced accommodation isn't as simple as listing your property on Airbnb and waiting for bookings. There are several things London landlords need to get right:

Planning permission and the 90-day rule. In most London boroughs, short-term letting is limited to 90 nights per year unless you have planning permission for a change of use. This is a critical detail. However, with proper planning consent or by focusing on stays of 90 nights or longer (corporate lets, relocation stays), you can operate legally year-round.

Mortgage lender consent. Your BTL mortgage lender needs to permit short-term letting. Some lenders already allow it, while others require you to switch to a specialist serviced accommodation mortgage. This is worth checking early in the process.

Setup and furnishing costs. A quality serviced accommodation setup requires investment in furniture, photography, linens, kitchenware, and smart locks. Expect to spend between £3,000 and £8,000 depending on the size and condition of the property. The good news is that these costs are fully deductible within your company.

Ongoing operational demands. This is the big one. Serviced accommodation requires active management: guest communications, check-ins, cleaning turnovers, pricing optimisation, review management, maintenance coordination, and restocking. Done well, it's a genuine hospitality operation. Done badly, it leads to poor reviews, low occupancy, and returns that don't justify the effort.

The Pitfalls to Watch For

The most common mistake landlords make is underestimating the operational intensity. Managing a serviced accommodation property yourself can quickly become a second job. Pricing too high kills occupancy. Pricing too low kills margins. Inconsistent guest experiences lead to mediocre reviews, which tank your listing visibility on platforms.

Another pitfall is ignoring seasonality. While London has strong year-round demand, there are softer months that require strategic pricing and marketing to maintain healthy occupancy. Without dynamic pricing tools and market expertise, many self-managing landlords leave significant revenue on the table.

Why Professional Management Changes Everything

This is where the comparison becomes stark. Running a traditional AST inside your limited company is simple but low-yielding. Running serviced accommodation yourself is high-yielding but operationally demanding. The sweet spot, and the option that more London landlords are choosing every quarter, is professional short-term let management.

At Airhosts, we manage the entire serviced accommodation operation for London landlords. That means professional photography, listing optimisation across all major platforms, dynamic pricing that responds to real-time demand, 24/7 guest communication, cleaning and linen management, maintenance coordination, and monthly owner reporting. You retain ownership and control inside your limited company while we handle everything that makes serviced accommodation actually work.

The result is hands-off income that typically exceeds AST returns by 30% to 80%, depending on the property and location.

Your Company Structure Is an Asset, If You Use It Properly

The decline in BTL company formations is a clear signal. The era of incorporating purely for tax efficiency on traditional lets is winding down. But for landlords who already have a company structure in place, the opportunity isn't behind you. It's simply shifted.

Serviced accommodation and corporate lets represent the highest-yielding, most tax-efficient use of a limited company property portfolio in London today. And with Airhosts managing the operation, you don't need to become a hospitality expert to capture those returns.
