    Single Brick Construction Mortgages

    Single brick properties are classed as non-standard construction, but mortgages are available. We find specialist lenders who understand single skin builds.

    What Is Single Brick Construction?

    Single brick (also called single skin) construction means the external walls are built with just one layer of bricks, rather than the standard cavity wall with two layers. This is common in older properties, particularly Victorian and pre-war homes, as well as some outbuildings and extensions. While structurally sound when maintained, many mainstream lenders are cautious about single brick properties due to concerns about damp, insulation, and thermal efficiency.

    • Specialist lenders who accept single brick construction
    • Knowledge of single skin wall mortgage criteria
    • Properties with damp-proofing and insulation improvements considered
    • Both residential and buy-to-let options available

    Your home may be repossessed if you do not keep up repayments on your mortgage.

    Why Are Lenders Cautious?

    Single brick walls lack the cavity (air gap) found in standard construction. This makes them more susceptible to damp penetration and means they offer less thermal insulation. Lenders worry about ongoing maintenance costs and potential structural issues. However, many single brick properties have been successfully improved with internal insulation and damp-proofing.

    Improving Mortgage Prospects

    If your single brick property has been upgraded with internal or external insulation, damp-proof courses, or rendered/weatherproofed externally, your mortgage options improve significantly. Having evidence of these improvements (building regulations certificates, contractor receipts) strengthens your application.

    Survey Requirements

    Lenders typically require a detailed survey for single brick properties, often a Level 3 (full structural) survey. The surveyor will assess the condition of the brickwork, look for signs of damp, and check whether any improvements have been made. A positive survey report opens up more lending options.
