A large panel system (LPS) property is a home built with big prefabricated concrete panels, often after the Second World War. These homes helped meet housing needs quickly but are now classed as non-standard construction. Many mortgage lenders treat them differently from traditional brick houses.

What Is a Large Panel System Mortgage
A large panel system mortgage is a home loan designed for buyers of LPS properties. Because the walls and structure are built from large concrete panels joined together, some lenders see higher risks of structural movement or weather damage.
This means extra checks and sometimes stricter loan terms compared with a standard house.
Challenges and Lender Rules
Structural Integrity
Lenders often ask for detailed surveys to show that the panels and joints are safe. A structural engineer or a RICS Level 3 survey is common.
Insurance and Repairs
Home insurance can cost more or need extra documents. If the home has been repaired under an approved scheme, proof such as a PRC repair certificate helps.
Deposit and Loan-to-Value
Many lenders ask for a larger deposit than on a brick house. Loan-to-value (LTV) limits can be lower.
Valuation and Eligibility
Surveyors check if the property can be sold again easily. Only homes that meet these checks are usually accepted.
How To Improve Your Chances of Approval
Choose the right survey: Ask for a full structural or RICS Level 3 report.
- Prepare documents early: Gather repair certificates, building control approvals and planning permissions.
- Save a larger deposit: A bigger deposit can reduce the lender’s risk.
- Show strong credit history: Keep other debts low and make all payments on time.
- Use a specialist broker: A broker familiar with LPS rules can help find suitable lenders and speed up the process.
