RICS Level 3 Building Survey in SE15

The SE15 postcode encompasses some of South London's most characterful but potentially problematic housing stock. Properties here range from grand Victorian terraces in conservation areas to purpose-built flats and modern new-build apartments. Each type brings its own set of potential issues that our surveyors are trained to identify. Victorian and Edwardian properties, which form a significant portion of the housing stock, often have solid brickwork construction but can suffer from aging timber elements, previous unspecified alterations, and the effects of decades of wear.

The local geology in SE15 presents specific challenges that our inspectors always consider. The area sits on clay soil, which is prone to shrink-swell movement depending on moisture levels. This ground movement can lead to subsidence, particularly where trees or large shrubs are planted near properties. We've seen properties on roads like Kirkwood Road in Nunhead with historic subsidence claims related to root-induced clay shrinkage. Our surveyors examine the external environment for signs of this type of movement, including cracking patterns, uneven floors, and doors that stick or don't close properly.

Many properties in SE15 have been converted into flats over the years, and these conversions often have shared structural elements that require careful assessment. The quality of conversion work varies considerably, and our Level 3 survey examines the condition of shared walls, floors between levels, and any structural modifications that have been made. For properties in conversion flats, understanding the condition of the whole building is just as important as examining your own unit.

SE15 also contains numerous listed buildings, predominantly Grade II, with the former Pioneer Health Centre in St Mary's Road holding Grade II* status. Our surveyors understand the additional considerations that come with listed properties, including identifying where previous owners may have carried out unapproved modifications that could affect your ability to obtain listed building consent for future works.

• Flat conversions and shared structures
• Clay soil and subsidence risk
• Electrical and plumbing age
• Roof condition and age
• Damp and timber decay

While SE15 has seen significant new development in recent years, including schemes like Bermondsey Heights on Ilderton Road and Ledbury Way on Commercial Way, new-build properties still benefit from a professional survey. At these developments, you might think that a building is in perfect condition, but our experience shows that even new construction can have defects that are not immediately visible. Developers like Barratt London and Higgins Homes build to different specifications, and independent inspection provides you with confidence in your investment.

New-build apartments in SE15 range from the more affordable options at developments like Burcher Gale Grove, where one-bedroom apartments start from around £285,000, through to premium developments like Rye Parkside near Peckham Rye Park, where prices reach £850,000 for larger units. Regardless of price point, our Level 3 survey can identify any construction defects, issues with sound insulation between flats, and problems with windows, doors, or mechanical systems that may not be apparent during a viewing.

For those purchasing off-plan, a survey before completion gives you leverage to request corrections from the developer. Even for completed new builds, we check items like balcony integrity, window installation quality, and the effectiveness of waterproofing in bathrooms and kitchens. The 10-year building warranty that comes with new developments provides protection, but identifying issues early often means simpler resolutions.

At Rye Parkside, where completion is estimated for March 2026, we can conduct a snagging inspection to identify any finishing issues before you move in. This is particularly valuable for new-build apartments where small defects like poorly sealed windows or uneven finishes can lead to bigger problems down the line.

While SE15 has a very low immediate flood risk from rivers and groundwater, with no current flood warnings in place, the London Borough of Southwark's preliminary flood risk assessment identifies surface water flooding as a concern for areas like Peckham. During heavy rainfall, certain areas can experience surface water pooling, and our surveyors note any indications of previous flooding or water damage during their inspection. Research indicates that an estimated 33,220 residential properties in the London Borough of Southwark could be at risk of surface water flooding during a 1 in 200 annual chance rainfall event.

The geology of SE15 presents another important consideration. The clay soil that underlies much of the area is reactive to moisture changes, expanding when wet and contracting during dry periods. This shrink-swell behaviour can cause ground movement that affects foundations, particularly where trees are planted close to buildings. Our surveyors examine the external grounds for signs of this type of movement, including cracking to external walls, gaps around window frames, and evidence of previous foundation movement. Understanding these ground conditions is essential for any property purchase in SE15, particularly for older buildings that may have shallower foundations than modern standards require.

The permeable substrate underlying large areas of SE15 also contributes to groundwater flooding risk. Properties in lower-lying parts of the area may be more susceptible to groundwater issues, particularly in areas with high water tables. Our surveyors will check for signs of past groundwater problems, including damp proof course failures, salt staining on walls, and deteriorated skirting boards.
