A Broker’s Guide to Our Semi-Commercial BTL Lending

The UK property market is always shifting, and as a broker, your ability to guide your clients toward high-performing asset classes is exactly what sets you apart. As the market evolves toward more professional portfolio landlords, your clients are seeking to invest in properties that can offer higher yields and returns through HMOs and MUFBs. 

According to market forecasts, total UK commercial property lending is on a sharp upward trajectory, projected to climb from £90 billion in 2023 to a staggering £118 billion by 2028.

A massive driver of this broader commercial growth is the semi-commercial sector, which is rapidly gaining popularity among seasoned and expanding investors alike. The continuous growth highlights a profound and sustained shift in the industry:

• Sustained Volume Growth: Following a massive year in 2024, where total applications doubled compared to 2023 data, the momentum has surged even further. Applications for semi-commercial properties climbed by another 58% in the first half of 2025 compared to the same period in 2024.
• Increasing Portfolio & Market Share: By the end of 2024, semi-commercial applications accounted for an impressive 24% of all commercial lending activity. This footprint has only solidified, with semi-commercial purchase applications rising by 31% year-on-year as a proportion of all specialist lending applications, proving that the asset class is a permanent fixture of modern portfolio design rather than a passing trend.
• The Dominant Popularity Mix: Within the semi-commercial sector, retail units with residential flats above remain the undisputed favourite, making up 69% of all mixed-use applications (up from 60% previously).

Why are property investors shifting their capital into this specific niche so aggressively? From a strategic standpoint, it boils down to two major structural advantages:

• Dual Income Potential: Investors are highly attracted to the ability to generate two distinct streams of rental income from entirely different types of tenants, all secured under one single title.
• Favourable Tax Treatment: These mixed-use assets frequently enjoy highly advantageous tax treatments, particularly in relation to Stamp Duty Land Tax (SDLT), which drastically improves the entry economics and ongoing profitability for buyers.

Understanding the Asset: What Qualifies as Semi-Commercial?

Now that we see exactly why demand is surging, let’s clearly define what constitutes a semi-commercial property under our lending guidelines.

In basic terms, a semi-commercial property is a mixed-use asset that typically consists of a residential property located directly above a trading business. However, to qualify for our new product range, the property must adhere to several structural and operational rules:

• Independent Operations and Separate Access: The property must possess completely separate access points for both the residential and commercial elements. This structural requirement ensures that both parts of the building can operate independently of each other without shared entryways.
• A Single Freehold Title: Even though the two elements function completely independently, both the commercial space and the residential units must be held on a single freehold title.

The dual nature of the property is also reflected in how the tenancies are managed:

• Residential Tenancies: The residential component of the property is normally let out to tenants utilising a standard Assured Shorthold Tenancy (AST) agreement.
• Commercial Leases: The ground floor or trading business element operates under a traditional commercial lease.
