Understanding the Differences Between Short-Term, Mid-Term, and Corporate Lets for London Landlords

London’s rental market is unique and complex. Many landlords make the mistake of treating all non-Assured Shorthold Tenancy (AST) lets as the same. This misunderstanding can lead to costly errors, regulatory issues, and missed opportunities. Short-term, mid-term, and corporate lets each serve different tenant needs, come with distinct risks, and face different rules—especially in London.

This post explains these three letting models clearly, helping landlords choose the right approach and avoid pitfalls in one of the world’s most challenging rental markets.

Why London’s Rental Market Demands Clarity

London is not like other UK cities when it comes to renting property. It has:

• A 90-day limit on short-term lets without planning permission

• Borough councils that closely monitor letting activity

• Dense residential areas where neighbours are sensitive to frequent guest turnover

• High professional mobility, creating demand for various rental durations

  
  

Using the wrong letting model or misunderstanding which one applies can expose landlords to fines, legal challenges, and tenant disputes. It can also affect profitability and property maintenance.

Short-Term Letting: Holiday and Visitor Use

What It Is

Short-term lets usually last less than 30 days. They cater to visitors and tourists who want a temporary place to stay. Bookings often happen through platforms like Airbnb or Booking.com, with frequent guest turnover.

Where It Works

• Prime tourist areas such as Westminster, Kensington, and Camden

• Properties near event venues or major transport hubs

• Flats or houses with features attractive to short stays (e.g., fully furnished, central location)

  
  

Regulatory Considerations

London restricts short-term lets to 90 nights per calendar year without planning permission. This rule aims to protect long-term housing supply and reduce disruption in residential communities.

Risk Profile

• High operational demands due to frequent cleaning and guest management

• Increased risk of neighbour complaints about noise or security

• Strict compliance needed to avoid fines or enforcement action

  
  

Short-term letting can be profitable but requires careful management and adherence to local rules.

Mid-Term Letting: Stays Between 30 and 90 Days

What It Is

Mid-term lets cover stays from one month up to three months. These are longer than typical holiday lets but shorter than standard tenancy agreements. Pricing may be nightly or weekly.

Typical Guests

• Contractors working on short projects

• Professionals relocating temporarily

• People between homes or waiting for permanent accommodation

  
  

Why Landlords Use Mid-Term Lets

• Lower tenant turnover compared to short-term lets

• Reduced wear and tear on the property

• More predictable income streams

• Less neighbour disruption

  
  

Mid-term lets fill a gap between tourist rentals and long-term housing, offering flexibility for both landlords and tenants.

Corporate and Professional Residence Letting: Long-Term Stays Over 90 Days

What It Is

Corporate lets usually last 90 days or more. Tenants use the property as their main residence during this time. Pricing is often monthly, with invoicing tailored for companies or professionals.

Typical Guests

• Relocated employees on fixed-term contracts

• Professionals on secondments

• Executives needing furnished accommodation

  
  

Benefits for Landlords

• Stable, longer-term income

• Lower tenant turnover and maintenance costs

• Clear legal framework under AST or company agreements

  
  

Corporate lets require properties to meet higher standards of comfort and furnishing, but they offer reliable returns and fewer regulatory headaches.

Choosing the Right Model for Your London Property

Landlords should assess their property location, target tenant group, and willingness to manage operational demands. For example:

• A flat near the West End might suit short-term lets during peak tourist seasons but must respect the 90-night limit.

• A property near business districts like Canary Wharf may attract mid-term lets for contractors or project workers.

• Larger, well-furnished apartments in zones with many corporate offices can be ideal for professional residence lets.

  
  

Understanding these differences helps landlords avoid fines, reduce tenant disputes, and maximize rental income.

Practical Tips for London Landlords

• Check local borough rules before listing your property for short-term lets.

• Keep detailed records of guest stays to ensure compliance with the 90-night limit.

• Consider professional management if you choose short-term letting to handle cleaning and guest communication.

• Screen tenants carefully for mid-term and corporate lets to ensure they fit the property and lease terms.

• Invest in quality furnishings and maintenance to attract corporate tenants who expect comfort and reliability.

  
  

Final Thoughts

London’s rental market demands clear understanding of letting models. Short-term, mid-term, and corporate lets serve different tenant needs and come with distinct risks and regulations. Landlords who know these differences can protect their investments, comply with local laws, and tap into the right tenant markets.
