Mid-Term Lets Explained: The Smart Choice for London Property Owners in Winter

When London’s short-let season winds down in September, the question every managed property owner faces is the same: what happens to the asset for the next seven months? The answer, for the best-managed prime London properties, is a mid-term let — and it is more straightforward, more profitable, and more flexible than most owners expect.

Key Takeaways
  • A mid-term let is a furnished tenancy of one to six months, typically to a corporate or relocating professional tenant
  • Mid-term lets are not subject to London’s 90-day short-let cap — they operate under a separate legal framework
  • Winter corporate demand in London is consistent and well-funded — tenants are typically on company relocation or project budgets
  • Monthly returns on mid-term lets typically exceed a comparable long-let by 20–40%, while retaining owner flexibility
  • Curated Property manages the full short-let to mid-term transition seamlessly — no gap in management, no void risk

What Is a Mid-Term Let?

A mid-term let — sometimes called a medium-term let or corporate let — is a furnished residential tenancy lasting between one and six months. It sits between a short-let holiday rental (typically two to fourteen nights) and a standard long-let assured shorthold tenancy (typically twelve months or more). In London’s prime property market, mid-term lets are almost always corporate or professional: the tenant is an executive on a project assignment, a professional relocating to London, a Harley Street patient requiring extended accommodation, or a family between permanent homes.

The legal structure differs from both a holiday let and a standard AST. Mid-term lets are commonly arranged as company lets — where the tenant’s employer signs the agreement rather than the individual — or as short assured tenancies of less than six months. In either case, the owner retains significantly stronger possession rights than under a standard long-let, and the property remains in professional management throughout.

For prime London property owners, the mid-term let is not a compromise or a fallback. Used correctly, it is the second half of a deliberately designed annual strategy that begins with peak-season short letting and transitions seamlessly into winter corporate demand.

“The short-let calendar ends in September. The property’s earning potential doesn’t. Mid-term corporate tenants fill the winter months at rates that make leaving a prime London property empty — or defaulting to a long-let — a decision most owners quickly regret.”

Why Winter Creates the London Short-Let Gap

London’s short-let demand follows a clear seasonal pattern. The peak window runs from late April through September, driven by international leisure tourism, the summer cultural calendar, school holidays and the long evenings that make London an exceptionally attractive destination. During these months, a well-managed prime property commands strong nightly rates with consistent occupancy.

From October, the picture changes. Leisure demand drops sharply. International visitors thin out. And for most London properties, the 90-night annual short-let allowance will have been largely or entirely used during the peak season anyway. The property that was fully occupied at £700 per night in August faces a stark choice in November: accept significantly lower short-let occupancy at reduced rates, pivot to a long-let and lose flexibility, or transition to mid-term corporate management and fill the winter at steady, well-funded monthly rates. The third option — mid-term letting — is consistently the strongest.

The Mid-Term Tenant Profile: Corporate London in Winter

London’s corporate relocation and project market runs year-round, but winter is particularly active. Companies complete financial year-end moves in October and November. International executives arrive for Q4 projects and stay through to the new year. Medical professionals take up Harley Street placements in the autumn. Law firms and investment banks accommodate secondments and client-facing teams in furnished properties close to their offices. These tenants are not browsing Airbnb for a bargain. They are working from company budgets, with accommodation requirements set by their HR or travel departments, and they expect a property that meets a professional standard.

What distinguishes corporate mid-term tenants from both short-let guests and long-let tenants is predictability. They arrive on a confirmed date, leave on a confirmed date, pay on time (often directly through their employer), treat the property professionally, and raise maintenance issues through proper channels. For a Pimlico townhouse or a Chelsea apartment under Curated Property management, the transition from a summer of short-let guests to a winter of corporate mid-term tenants is not a downgrade — it is a different gear of the same well-managed machine.

“Corporate tenants on company-funded stays are among the most straightforward to manage. They arrive with a checklist, leave on time, and treat the property as the asset it is. The reviews they leave are written like business reports — precise, accurate, and almost invariably positive when the property is well managed.”

Mid-Term vs Short-Let vs Long-Let: An Honest Comparison

The right letting strategy depends on timing, property type, and owner objectives. The following comparison is specific to prime central London properties managed to a high standard in the October to April off-peak period.

Letting Type Typical Term Monthly Return (3-bed, prime) Owner Flexibility Regulatory Risk
Short Let (peak, May–Sept) 2–14 nights £8,000–£14,000 Full 90-day cap applies
Mid-Term Let (Oct–Apr) 1–6 months £5,500–£9,000 High No cap
Short Let (off-peak, Oct–Apr) 2–14 nights £3,500–£6,000 (at 60% occupancy) Full 90-day cap may be exhausted
Assured Shorthold Tenancy 12+ months £3,500–£5,500 Low Section 21 abolished

The comparison makes the case plainly. A mid-term let in the October to April window delivers monthly returns that are 20–40% above a comparable long-let, with none of the legal exposure introduced by the Renters’ Reform Act’s abolition of Section 21. And it substantially outperforms off-peak short letting in London, where winter occupancy rates and nightly rates both decline significantly from their summer peaks.

The Curated Property Hybrid Model: How the Year Works

Curated Property designs every property’s annual programme around a single principle: the right letting model for the right season. For prime London properties, this means a structured two-phase year that is planned in advance, transitions without void periods, and is managed entirely by the Curated Property team.

May – September: Peak Short-Let The full 90-night allowance is deployed across the highest-demand months. Dynamic pricing via Wheelhouse captures maximum nightly rates. Leisure and international guests. Consistent occupancy. The property earns at its peak potential.
October – April: Mid-Term Corporate The property transitions to corporate mid-term management. Vetted professional tenants on one- to six-month agreements. Steady monthly income, no void risk, no 90-day constraint. The property earns through winter without compromise.

The transition between phases is managed entirely by Curated Property. Owners are not required to find tenants, negotiate agreements, arrange handovers, or manage the property between lets. The move from short-let to mid-term — and back again the following May — is seamless, planned, and invisible to the owner beyond the monthly reports they receive.

What Curated Property Manages on Your Behalf

Mid-term property management requires a different operational approach from short-let management, and a very different one from long-let management. The tenancy is longer than a short-let, so periodic check-ins and mid-term maintenance reviews matter. It is shorter than a long-let, so the property must be maintained to a standard ready for immediate re-letting at the end of the term. Curated Property manages every aspect of this from its Pimlico base.

Mid-Term Lets and the Renters’ Reform Act

The Renters’ Reform Act’s abolition of Section 21 ‘no fault’ evictions applies to assured shorthold tenancies — the standard long-let agreement that most residential landlords have historically used. Company lets and short assured tenancies of less than six months operate under different rules, and do not carry the same possession risk. For owners who previously relied on Section 21 to regain possession of their properties, mid-term letting via a company let or short assured tenancy structure is one of the legally cleanest routes to maintaining flexibility.

This is not legal advice, and Curated Property recommends that owners take independent legal guidance on their specific circumstances. What we can confirm from our own managed portfolio is that the mid-term letting model — structured correctly and managed professionally — has become an increasingly attractive alternative to the standard long-let for owners who want strong returns, full flexibility, and no Section 21 anxiety.

We provide honest projections, based on your specific property and location, of what a hybrid short-let and mid-term programme could realistically deliver.

Frequently Asked Questions

What is a mid-term let in London?
A mid-term let is a furnished residential tenancy lasting between one and six months, typically to a corporate or professional tenant. It sits between a short-let holiday rental (days to weeks) and a standard long-let assured shorthold tenancy (12 months or more). In London, mid-term lets are commonly structured as company lets — where the tenant’s employer signs the agreement — or as short assured tenancies below six months.
How long is a mid-term let in London?
Most mid-term lets in London run for one to six months. The most common durations are one month (for project-based corporate stays), three months (for seasonal or secondment placements) and six months (for executives on longer assignments or families between permanent homes). Curated Property tailors the tenancy length to the property’s annual programme, ensuring the property is available to return to short-let management for the following peak season.
Do mid-term lets count towards the 90-day short-let rule in London?
No. London’s 90-night annual cap on short-term lettings applies to holiday-style rentals where individual stays are less than 90 consecutive nights and the property is not the host’s primary residence. Mid-term lets of one month or more, structured as company lets or short assured tenancies, are not classified as short-term holiday lets and do not count towards the 90-night allowance. Curated Property structures all lettings to comply fully with applicable regulations.
How much does a mid-term let earn in London?
Monthly returns on mid-term lets for prime central London properties typically range from £3,800 to £18,000 per month, depending on property size, location and specification. A three-bedroom property in Pimlico or Kensington typically achieves £4,500–£7,500/month on a mid-term let. The same property on a standard long-let AST would typically achieve £3,500–£5,000/month. Mid-term lets consistently outperform long-lets by 20–40% while retaining owner flexibility.
Is a mid-term let affected by the Renters’ Reform Act?
The Renters’ Reform Act’s abolition of Section 21 applies to assured shorthold tenancies. Company lets and short assured tenancies of less than six months operate under a different legal framework and are not directly affected by Section 21 abolition in the same way. For owners concerned about possession rights under a standard AST, mid-term letting via a correctly structured agreement is one of the legally cleaner alternatives. Curated Property recommends independent legal advice on individual circumstances.
How does Curated Property manage the transition from short let to mid-term let?
Curated Property plans the transition from short-let to mid-term well in advance — typically by August for an October handover. The final short-let guest departs, the property undergoes a professional clean and inventory, and the first corporate mid-term tenant moves in without a void period. The process is managed entirely by Curated Property. Owners receive a monthly report and are not required to be involved in the transition at any stage.

Keep your property earning. All year.
