Thermographic Survey in Peterborough

Our thermographic survey captures a full infrared assessment of your Peterborough property. Using FLIR thermal imaging cameras, our inspectors measure radiated heat across every accessible surface - walls, ceilings, floors, windows, doors, and roof spaces - producing a report that maps thermal anomalies to precise locations within the building.

Insulation failure is one of the most common findings in Peterborough's older housing stock. In solid brick properties built before the 1940s, which are widespread in the PE1 city centre and the Westgate and Millfield areas, there is no cavity to fill with insulation. Our thermal cameras show exactly how heat is escaping through these walls by measuring the temperature drop across the masonry. In cavity wall properties from the post-war period, we identify sections where insulation has slumped or is missing entirely.

Damp is another primary focus. Cold surfaces within a wall or floor appear in a distinct thermal signature compared to dry areas, allowing our inspectors to trace the path of water ingress from the point of entry to where it pools. This is particularly relevant for Peterborough properties near the River Nene, where ground moisture levels are elevated, and in basement conversions or ground-floor extensions throughout the city.

Our survey also captures electrical hot spots in distribution boards, wiring routes, and sockets. Overloaded circuits and failing connections generate heat that appears clearly under infrared imaging. We record these findings and include them in your report alongside thermal images and recommended remedial action.

Peterborough sits on the Oxford Clay Formation and Kellaways Formation, a geology characterised by high clay content and alluvial deposits from the Fenland edge. Clay-rich ground is rated moderate to high for shrink-swell risk by the British Geological Survey, meaning that during dry summers it contracts and during wet winters it expands. This ground movement stresses the foundations of older properties, particularly Victorian and Edwardian terraces in PE1 and PE2, leading to cracking at wall junctions and around window and door openings.

Cracking in external brickwork creates pathways for rainwater to enter the wall structure. Thermographic imaging detects the resulting cold, damp patches behind the internal plaster that are invisible from a visual inspection. Our inspectors use damp meter readings alongside thermal imaging to confirm the presence of moisture within the wall, not just at the surface. This combination provides a more reliable diagnosis than either technique in isolation.

Subsidence movement also creates gaps at the junctions between walls and floors, and between walls and roofs. These cold bridges allow warm air from the interior to escape rapidly, appearing as dark areas in thermal images during a heated survey. Our report quantifies the extent of heat loss at each junction and notes where the cause may be structural movement rather than insulation failure, helping you decide whether specialist structural investigation is warranted alongside remediation.

With 95.3% of Peterborough property sales in 2025 involving established properties rather than new builds, the majority of buyers are purchasing homes with older heating systems, limited or absent cavity wall insulation, and roof spaces that may have insufficient loft insulation. These factors drive up energy costs and reduce EPC ratings. Our thermal survey provides a precise diagnosis of where the worst heat loss is occurring before you invest in insulation or a new heating system.

Solid wall properties - widespread in the Victorian and Edwardian streets of central Peterborough and in parts of Millfield, Woodston, and Fletton - cannot benefit from cavity wall insulation. The choice is between external wall insulation, which changes the appearance of the property, or internal wall insulation, which reduces floor area. Our thermal survey maps the actual heat loss across each wall face, allowing you to prioritise which walls most urgently need treatment and assess the likely payback period for the work.

Loft insulation is one of the highest-impact improvements in Peterborough's semi-detached and detached housing stock. Our thermal imaging of the ceiling plane shows where insulation is absent, compressed, or has slipped away from the eaves - all common in properties where insulation was installed in the 1980s or 1990s and has since degraded. We identify these gaps precisely so that installers know exactly where to target their work, rather than relaying the entire loft unnecessarily.

Peterborough city centre contains several conservation areas and a concentration of listed buildings, particularly around the Cathedral and the older streets of central PE1. Listed building consent and conservation area restrictions mean that external wall insulation and replacement windows are frequently prohibited, leaving buyers with limited options for improving the thermal performance of these properties. A thermographic survey is therefore particularly valuable for listed building buyers, as it defines the extent of heat loss from within the existing fabric before any works are planned.

In listed properties, our thermographic survey identifies opportunities for internal draught-proofing at sash windows, secondary glazing installations, and targeted internal insulation at the worst-performing wall sections - all interventions that can proceed without external consent. The thermal report provides the evidence base for discussions with the local planning authority if any internal works require listed building consent, demonstrating the thermal improvement achievable from each proposed intervention.

Cathedral-area properties and those within Peterborough's conservation areas often feature original features including timber sash windows, solid brick external walls, and suspended timber ground floors. Each of these elements is a significant source of heat loss and damp risk. Our inspectors assess each element systematically, recording thermal images at every window and door junction, across floor boards where access allows, and along the full perimeter of the ground floor where rising damp from clay soils is most likely to occur.
