The 4 Most Common SIC Codes for Limited Company BTL
If your limited company is an SPV designed solely for property investment, the following SIC codes are most appropriate:
68100 – Buying and Selling of Own Real Estate
Covers companies that buy and sell real estate for their own account.
Uses: Suitable for property flipping or trading, but it’s still acceptable for BTL purposes if your activities involve buying properties and holding them for rental income.
68320 – Management of Real Estate on a Fee or Contract Basis
68201 – Renting and Operating of Housing Association Real Estate
Covers companies involved in renting and operating residential real estate.
Uses: Suitable for landlords focusing solely on residential properties, excluding commercial properties.
Tip: Consult with an accountant or property expert to confirm which SIC code best suits your investment strategy.
Why Lenders Prefer SPVs Over Trading Companies
What is an SPV?
An SPV is a limited company established solely for a specific purpose, such as holding and managing rental properties. Unlike trading companies, SPVs have no additional business activities, making them simpler and more transparent for lenders.
Reasons Lenders Prefer SPVs
Simplicity and Transparency
SPVs have a single purpose, making their financial activities straightforward to assess. Trading companies often have multiple revenue streams, complicating financial reviews.
Reduced Risk
Lenders view SPVs as lower risk since they don’t engage in activities unrelated to property investment. Trading companies might face market fluctuations unrelated to the property sector, increasing risk.
Easier Underwriting
SPVs are typically structured with clean financials, focused solely on property income. Trading companies may have complex accounts with varied expenses, making it harder for lenders to evaluate.
Tax and Legal Protections
SPVs ensure separation of property-related liabilities from other trading activities, reducing risk for both lenders and landlords. Trading companies may expose landlords to greater tax and legal challenges.
Example: A trading company running a retail business might struggle to secure a BTL mortgage because its primary activity is unrelated to property investment. By contrast, an SPV focused solely on property rentals signals stability and predictability.
Consequences of Using the Wrong SIC Code
Selecting an inappropriate SIC code or operating a trading company can lead to:
Mortgage Rejections: Lenders may decline applications if the SIC code doesn’t reflect property investment activities.
Higher Interest Rates: Trading companies are perceived as higher risk, which may result in higher mortgage costs.
Regulatory Challenges: Inaccurate SIC codes can lead to compliance issues with Companies House and HMRC.
Tip: If you’ve chosen the wrong SIC code, you can update it through Companies House. Consult an accountant to ensure accuracy.
