Infrared thermal imaging to detect heat loss and hidden defects








Our thermal imaging specialists carry out detailed infrared surveys across Bognor Regis, from Steyne and Waterloo Square to North Bersted, Aldwick and Shripney Road. We detect heat loss that sits behind plaster, around window reveals, at roof junctions and through parts of the envelope that look normal in daylight. The camera does not guess, it records surface temperature patterns to 0.1C accuracy, which helps us show where energy is escaping and where moisture may be hiding.
Bognor Regis has a wide spread of housing, from Victorian seaside properties and Regency-styled terraces near the old town to 1920s and 1930s homes in Aldwick and Aldwick Bay, plus newer plots at Bersted and Pagham. That mix matters, because solid masonry walls, early cavity walls and modern timber frame details all lose heat in different ways. A thermal survey gives a practical read on comfort, bills and insulation performance, which is useful in a coastal town where wind, rain and salt air can put extra pressure on the building fabric.

A thermal scan shows far more than a patch of cold wall. It can highlight missing loft insulation, collapsed cavity wall fill, cold bridging at junctions, draughts around doors and windows, and moisture patterns that point to hidden damp. Our surveyors also look for underfloor heating faults and electrical hotspots where the surface temperature does not match the rest of the room or elevation.
Around the Steyne and Waterloo Square Conservation Area, older masonry details often hide leaks at roof level and around replacement joinery. In North Bersted and Felpham, post-war semis can show patchy insulation or gaps left behind after later alterations. The infrared image gives a clear starting point, then we explain what is likely to be insulation loss, what may be a moisture issue, and what needs a closer check.

Bognor Regis has a housing mix that rewards a closer look. The town centre includes Victorian seaside homes and Regency-styled terraces, while Aldwick and Aldwick Bay hold many grand 1920s and 1930s properties. Those older houses were built before modern insulation standards became routine, so solid walls, timber floors and uninsulated roof spaces can lose heat quickly, especially along exposed coastal elevations near the promenade and the Railway Station conservation area.
Newer places tell a different story. Nursery Fields in Bersted has planning permission for 225 new homes, with 70% private and 5% self-build, while New Barn Lane in Bersted delivered 90 new houses and bungalows that are now occupied. Even modern homes can show thermal weak spots around service penetrations, dormers and roof-wall junctions, so our infrared surveys still add value. London Clay Formation beneath parts of the town, together with sands, silts and gravels in the historic core, also makes it sensible to watch for movement cracks and the air leakage that often follows them.
Thermal imaging turns wasted energy into something you can see. Typical findings show around 25% of heat escaping through the roof, 35% through walls and 15% through windows, which makes the case for loft top-ups, cavity work and better glazing seals much easier to understand. That picture helps homeowners in places like Aldwick Road, Upper Bognor Road and Shripney Road focus on the parts of the home that are doing the most damage to comfort.
Our report links each hotspot to a sensible next step, such as topping up loft insulation, improving airtightness, sealing junctions or reviewing a suspect damp area. For a property near the Bognor Regis Railway Station conservation area, a small defect around a bay window or roofline can have a bigger effect than expected. The point is not just to show the cold patch, but to show where the building is losing useful heat and where money is slipping out with it.

Start with a quick quote through our booking form. We confirm access, property type and the best time to survey.
Thermal contrast is strongest from October to March. We look for at least a 10C difference between inside and outside.
The heating should be on for at least 2 hours before the survey so the structure reaches a stable temperature pattern.
Our surveyors carry out external and internal infrared scans, checking walls, roofs, floors, windows, doors and service penetrations.
We compare temperature variations, discard false readings from reflections or recent sun, then annotate the key findings.
You get a clear report with thermal images, notes on likely causes and practical recommendations for the next step.
Thermal images use a colour scale, usually from cold blues through greens to hot reds and whites. Cold areas often point to missing insulation, draughts or wet materials, while warmer bands can show heat building up behind a defect or around electrical equipment. The picture is only useful when it is read in context, so our surveyors compare the image with the room layout, the weather conditions and the construction type before drawing a conclusion.
False readings can appear after bright sun, on reflective surfaces or on south-facing walls that have warmed up during the day, which is common on properties close to the seafront in Bognor Regis. Glazed doors, shiny metal trim and recent rain can also alter the surface reading. That is why we annotate each image and explain why a mark is likely to be an insulation gap, a moisture path or just a surface effect that does not need repair.
Victorian terraces around Steyne and Waterloo Square often show single-glazed windows, weak loft insulation and cold bridging at chimney breasts. In older solid-wall homes, the heat loss pattern can be broad and obvious, because there is no cavity to retain warmth in the first place. Our infrared camera picks up those losses fast, then the report explains whether the issue sits in the roof, the wall build-up or the junction between the two.
Aldwick and Aldwick Bay bring a different set of findings, usually tied to 1920s and 1930s construction, later alterations and patchy retrofit work. In North Bersted and Felpham, we often see cavity insulation that has moved, settled or been installed unevenly, which leaves cold stripes in external walls. Homes near Shripney Road or the Tesco superstore area can also show signs of moisture stress after surface water flooding, so the thermal pattern needs to be read alongside the local exposure and any sign of staining.

A thermal imaging survey can detect heat loss, missing or collapsed insulation, draughts, cold bridging, hidden damp and some electrical hotspots. It can also show where a floor, roof or wall is performing differently from the rest of the building. Our surveyors then explain which findings are likely to be worth fixing first.
Our thermal imaging surveys in Bognor Regis start from £300. The final cost depends on the size of the property, access, and whether the home needs a full external and internal scan. Larger homes in Aldwick or older properties near the town centre can take longer to assess, so the quote may move up from the starting price.
October to March is the best window, because the colder weather gives stronger thermal contrast between indoors and outdoors. We also need at least a 10C difference to read the building fabric properly. Heating should be on for at least 2 hours before the survey, which helps the images show genuine heat loss rather than a cold-start effect.
Most surveys take 1-2 hours, depending on the size and layout of the property. A flat near Bognor Regis Railway Station will usually be quicker than a larger detached house in Aldwick Bay or a long terrace in the town centre. The analysis and report preparation happen after the visit.
Yes, it can help identify patterns linked to damp, moisture ingress and condensation. The camera shows temperature differences, so a wet patch often appears differently from dry surrounding material. Our surveyors still interpret the image carefully, because some cold areas are caused by insulation gaps rather than water.
We ask for the heating to be on for at least 2 hours before the appointment and for windows to be closed. Curtains, furniture or stored items that block walls and ceilings can hide useful detail, so it helps to clear those areas where possible. Access to loft hatches, external walls and problem rooms makes the survey faster and more useful.
No, it sits alongside a building survey rather than replacing it. Thermal imaging is brilliant for finding heat loss and moisture patterns, while a RICS Level 2 or Level 3 survey checks the wider condition of the home. For a property in one of Bognor Regis’s conservation areas, both reports can work well together.
Thermal imaging surveys in Bognor Regis start from £300, which makes them a practical addition to a pre-purchase check or an energy-efficiency review. The price covers external and internal infrared scans, image analysis and an annotated report that explains the findings in plain language. For homes near Steyne and Waterloo Square, or a larger house in Aldwick Bay, the time needed on site can be longer, so size and layout have a direct effect on the final quote.
Our thermal imaging specialists look for the clearest weather window before booking the visit, because the quality of the result depends on contrast as much as on the camera. A home in the old town, a flat by the station, and a new build in Bersted will all need a slightly different approach. The report then points to sensible upgrades, from loft insulation and draft sealing to a fuller follow-up survey where the thermal pattern suggests a deeper building issue.
