Infrared thermal imaging to detect heat loss and hidden defects








Our thermal imaging specialists carry out detailed infrared surveys across Shoreham, including homes in the TN14 area where older brickwork, later extensions and mixed insulation histories can hide cold spots. We detect temperature differences that the eye cannot see, then turn those readings into clear findings you can act on. An infrared camera measures surface temperature variations to 0.1C accuracy, so we can pick out heat escaping through weak points in the building fabric. The result is a practical report that shows where comfort is being lost and where energy is being wasted.
Shoreham sits within the wider Sevenoaks area, where conservation area properties and period homes often sit alongside later builds. That mix matters, because a Georgian, Victorian or Edwardian house behaves very differently from a post-war semi or a newer flat. Higher energy bills usually start with small defects, such as air leakage, thin loft insulation or a cold bridge at a wall junction. Our thermal surveys show those faults early, before they turn into larger repair bills or persistent draughts.

Our infrared scans reveal heat loss through walls, roofs, floors and windows, plus the small gaps that often cause the biggest discomfort. We pick up missing or disturbed cavity wall insulation, cold bridging at junctions, air leakage around doors and windows, and thermal patterns linked to damp or moisture ingress. The same camera can also flag underfloor heating faults and electrical hotspots, which helps us separate normal heat movement from a real defect. In a Shoreham property, those clues often point straight to the part of the building that needs attention.
Thermal imaging is non-invasive and non-destructive, so we do not need to lift floors or open walls to find a problem. The survey works best when the inside and outside temperatures differ by at least 10C, which is why October to March usually gives the sharpest results. We also ask for the heating to be on for at least 2 hours before the appointment, because a warm building makes hidden defects easier to read. That extra contrast helps our surveyors build a cleaner, more accurate picture of the home.

Shoreham's conservation area and the wider Sevenoaks housing stock include Georgian, Victorian and Edwardian homes with solid brick walls, plus later properties that have been altered over time. Solid wall construction behaves differently from cavity wall construction, because heat moves through the fabric more readily and cold bridges show up more clearly at junctions. Older roofs often carry patchy insulation too, especially where a loft has been upgraded in stages rather than as one planned project. Our surveyors use thermal imaging to show which parts of the building are losing heat first, so the next repair can be targeted rather than guessed.
Homedata.co.uk records show Kent logged 21,000 property sales in the previous 12 months, a drop of 13.6% or 4,000 transactions, with 497 new-build sales making up 2.4% of the total. That split matters for thermal analysis, because terraces, semis, detached homes and flats each lose heat in different ways. Kent's sales mix between April 2025 and March 2026 was Terraced at 32.4%, Semi-Detached at 28.8%, Detached at 22.4% and Flat at 16.3%, according to homedata.co.uk. In a place like Shoreham, that variety means one survey format has to read solid brick, modern cavity wall, and converted space with equal care.
The price backdrop adds another layer. Homedata.co.uk places the South East average house price at £385,000 with a +1.8% year-on-year change, while the UK average sits at £284,000 with a +2.0% change as of April 2026. Home.co.uk shows Kent's average asking price at £444,598 with 0.0% movement, and the UK average asking price at £452,249 in May 2026. In that context, a thermal defect that quietly wastes energy can have a real effect on monthly costs, comfort and the appeal of the home.
Thermal imaging turns hidden heat loss into something visible and measurable. A warm roofline, a bright patch around a lintel, or a cold stripe at a wall junction tells us where the building fabric is underperforming. In many homes, around 25% of heat is lost through the roof, 35% through walls and 15% through windows, so the camera often points us straight to the biggest opportunities first. That is useful because it helps a homeowner focus on the measures that can reduce wasted energy fastest.
Our report links each thermal finding to a practical fix, such as topping up loft insulation, sealing air leaks, correcting cavity fill issues or improving glazing performance. We do not promise a one-size payback period, because the return depends on the size of the defect, the property type and the cost of the repair. We do show which upgrades are likely to have the most impact, so the next step is based on evidence rather than guesswork. That approach works especially well in Shoreham, where older fabrics often need a staged upgrade plan rather than a single dramatic intervention.

Start with a quick quote through our thermal survey booking page. We confirm the property type, access points and any areas you want us to focus on.
We schedule the visit for the best available conditions, ideally between October and March, when thermal contrast is strongest.
Keep the heating on for at least 2 hours before the appointment. That gives our surveyors a stable temperature baseline to read.
Our thermal imaging specialists carry out infrared scans inside and outside the home, looking at roofs, walls, windows, floors and junctions.
We review each image, rule out false readings where possible and annotate the problem areas so the findings are easy to follow.
You receive a report with thermal images, explanations and recommendations, usually focused on the fixes that can cut heat loss and improve comfort first.
Thermal images are read by colour, not by guesswork. Cold areas usually show as blue, purple or darker tones, while warmer areas move towards red, orange or white, depending on the camera palette. A cold streak across a ceiling edge can point to missing loft insulation, while a bright patch around a radiator pipe may be showing heat escaping through a gap. Our surveyors explain each image in plain English, so you can see what the colour change means and why it matters.
Temperature difference matters as much as colour. A faint pattern may be normal, while a sharper boundary can suggest a clear defect in the fabric or a localised air leak. Reflections, direct sunlight and solar gain can distort readings, which is why we avoid poor survey conditions whenever possible and look at the building as a whole, not one image in isolation. Where a reading looks uncertain, we flag it carefully and explain what extra check would help confirm it.
Each report includes annotated images and a short explanation beside every finding, so there is no need to decode the picture yourself. We often compare one side of the home with another, or a similar room with a colder room, because patterns become easier to trust when they are viewed in context. That is useful in older Shoreham homes with solid brick walls, mixed upgrades and later alterations, since the building may have several different heat-loss behaviours in one property. The result is a report that shows you where the problem sits, how serious it is and what to do next.
Our surveyors often see the same patterns in Shoreham's older homes and in the wider Sevenoaks conservation area. Period properties with solid brick walls can show pronounced cold bridging at window reveals, floor edges and internal junctions, especially where insulation has been added in parts rather than throughout. We also find lofts with thin or uneven insulation, which creates clear heat loss tracks across the ceiling line. In homes that have been altered over the years, the newer section can behave very differently from the original structure.
Single glazing, ageing sealed units and draughty rooflights often show up as strong cold spots on the image. We also find blocked or poorly installed cavity insulation in some later properties, plus uninsulated pipework or underfloor heating zones that are not performing as intended. Shoreham homes inside a conservation area can have tighter limits on external changes, so spotting the internal fabric issue first is especially useful. That gives homeowners a clearer route to repairs that respect the building while still cutting heat loss.

The sharpest survey results usually come from October to March, with at least 10C difference between indoors and outdoors. Keep the heating on for at least 2 hours before we arrive, close windows and avoid using extract fans just before the scan. The full visit usually takes 1-2 hours depending on property size, and that gives us enough time to inspect the main heat-loss routes without rushing the images.
Our thermal imaging specialists can detect heat loss through walls, roofs, floors and windows, plus missing insulation, air leakage, cold bridging and thermal patterns linked to damp or moisture ingress. We also look for underfloor heating faults and electrical hotspots where the surface temperature pattern suggests a problem. The survey is non-invasive, so we can identify hidden issues without opening up the building fabric.
Our thermal imaging surveys in Shoreham start from £300. The final price depends on property size, layout and how much internal and external scanning is needed. The report includes annotated thermal images and practical recommendations, so you know what each hotspot means.
October to March usually gives the best conditions because the temperature difference between inside and outside is easier to create. We look for at least 10C difference, which gives the infrared camera more contrast to work with. That does not mean summer surveys are impossible, but the image quality is often less clear.
Most surveys take 1-2 hours, depending on property size and access. A larger home or a building with several levels may take longer because we need to scan the key surfaces carefully. After the visit, we analyse the images and prepare the report.
Thermal imaging can highlight patterns that point to damp, moisture ingress or condensation, but it does not replace a moisture meter or a full diagnosis where active damp is suspected. Cold patches, evaporation patterns and localised temperature changes often help us narrow down the source. We then explain whether the image suggests a leak, a cold bridge or another cause.
Yes, a little preparation helps the images read properly. Keep the heating on for at least 2 hours before the appointment, close external doors and windows, and avoid running fans or opening vents right before we arrive. Clear access to loft hatches, boiler cupboards and any areas you want us to inspect.
We review the thermal images, annotate the key defects and explain the likely cause of each issue. You receive a report that shows where heat is escaping and which repairs are likely to make the biggest difference first. That makes it easier to plan insulation, sealing or repair work with less wasted spend.

Our thermal imaging surveys in Shoreham start from £300, and that price suits homeowners who want a targeted view of heat loss without opening up the building fabric. The visit includes external and internal infrared scans, image analysis and an annotated report that explains the defects in plain language. We use the findings to separate general heat loss from specific issues such as missing insulation, air leakage or cold bridging. That keeps the next decision focused on the right repair rather than a broad guess.
Costs can move up if the property is larger, split over several floors or harder to access, because we need extra time to scan the main thermal paths properly. Accuracy also depends on the survey conditions, so the best results come when the home has been heated for at least 2 hours and the temperature difference is at least 10C. If the building is still carrying strong solar gain, the image may need careful interpretation or a later revisit. We always prefer the clearest reading possible, because a good thermal report should be useful the first time you open it.
For Shoreham homes in the conservation area, the value often sits in the detail. A solid wall showing cold bridging at a reveal, or a roofline showing uneven insulation coverage, gives a direct route to improvement. That is the kind of evidence that helps homeowners plan energy-saving work with more confidence. It also makes it easier to prioritise the repairs that will improve comfort, reduce draughts and lower wasted heat.
