- Damp Survey
Professional Heat Loss Survey
Energy bills only ever tell you that a property is losing heat, never where. A Heat Loss Survey answers that question properly. Fitzgerald Surveying Services carries out independent heat loss surveys for homeowners and landlords across South East England, using infrared thermal imaging to show exactly where a property’s fabric is failing to hold onto warmth, so any money spent on insulation or energy efficiency work goes where it will actually make a difference.
- Independent, qualified surveyors carrying out heat loss inspections, members of RICS, RPSA, CIOB and FODCS.
- 5-star rated from 67 Google reviews.
- Clear heat loss reports with practical, prioritised findings.

- About Heat Loss Survey
What Is a Heat Loss Survey?
A Heat Loss Survey, sometimes searched for as a home heating survey or simply a heating survey, uses the same infrared technology as a general thermal imaging inspection, but with one specific focus: showing where a building is losing heat, and how badly. An Energy Performance Certificate gives a property a modelled rating based on standard assumptions about its age and construction. This is not that. It is a physical, on-site inspection of the actual property in front of us.
That difference matters. Instead of an estimated rating on paper, you get a visual record of where heat is genuinely escaping, whether that is through the loft, around a window frame, at a wall junction, or through gaps left in cavity insulation years ago.
Our surveyors carry out the inspection during conditions that give the clearest results, generally when there is a decent temperature difference between inside and outside. The thermal images are then read against the property’s age and construction, since a 1930s solid-brick semi and a modern timber-frame home lose heat in genuinely different ways.

- Heat Loss Findings
What a Heat Loss Survey Can Detect
A home heat loss survey looks at a building as a whole, so what it uncovers depends entirely on how that particular property was built and how it has aged since. Because a thermal heat loss survey relies on the same underlying infrared technology throughout, most findings fall into one of the following categories.
Missing or Failing Insulation
Loft and cavity wall insulation can settle, slump, or simply have been installed with gaps in the first place. Thermal imaging shows this as an uneven pattern across a wall or ceiling, rather than the even coverage properly fitted insulation should give.
- Evidence of settled, slumped or missing insulation
- Uneven coverage patterns across walls and ceilings
- Findings relevant to loft and cavity wall upgrades
Cold Bridging
Heat tends to escape fastest at junctions. Where a wall meets a window frame, around a chimney breast, or at the edge of an extension: these are the points a thermal image picks up clearly, and they are often the easiest wins for improving comfort without a major project.
- Evidence of cold bridging at structural junctions
- Identification of extension and chimney breast heat loss
- Findings that support targeted, low-cost improvements
Draughts Around Doors, Windows and Loft Hatches
Cool air movement around an opening leaves its own distinct pattern on a thermal image. It is not always obvious from standing in the room, but it shows up plainly on screen, which is what makes it worth checking before assuming a whole wall needs attention.
- Evidence of draughts around doors, windows and hatches
- Areas identified for targeted draught-proofing
- Findings that avoid unnecessary, larger-scale work

- Why Choose Us
Why Choose Our Heat Loss Survey Experts
Local knowledge only means something when it sits alongside genuine technical expertise. We bring both: an understanding of how different types of South East England property hold and lose heat, and infrared training carried out to a recognised industry standard. A heat loss survey is not itself a RICS-accredited survey type. Every inspection at Fitzgerald Surveying Services is still carried out by a qualified, professionally accountable surveyor working to recognised standards.
Independent Perspective
We do not sell or install insulation, and we have no referral arrangements with contractors who do. As an independent heat loss survey UK provider, we tell you what is actually happening in your property, not what would suit a follow-on sale.
Findings You Can Act On
A heat loss survey is only useful if it leads somewhere. Where relevant, our findings connect naturally with a Home Energy Plan or a Retrofit Assessment, helping you prioritise upgrades by cost and impact rather than guesswork.
Building-Focused Assessments
Different construction types hold and lose heat in different ways. Knowing whether a property is solid-brick Victorian, cavity-wall 1930s or modern timber-frame lets our surveyors read a thermal image accurately, not in isolation.
Clear and Structured Reporting
Findings are set out in a straightforward format, making the report easy to review and refer back to afterwards.

- Our Process
From Booking to Heat Loss Report in 4 Clear Steps
Whether the concern is a consistently cold room, a rising energy bill, or planning ahead for insulation work, our process runs from initial enquiry through to a finished report, without unnecessary delay.
STEP 1
Discuss Your Requirements
We begin by discussing the property and the reason for the enquiry, whether that is a cold room, a high energy bill, or planning ahead for retrofit work.
STEP 2
Arrange a Suitable Inspection Date
We then arrange a convenient time, factoring in the conditions that heat loss imaging genuinely needs to work well.
STEP 3
Heat Loss Inspection
Our surveyor scans the property's external walls, roof and openings using an infrared camera, recording the conditions at the time so the results can be read accurately.
STEP 4
Receive Your Heat Loss Report
Your report follows shortly after, delivered digitally with thermal images, plain explanations and prioritised next steps included.
- FAQ
Heat Loss Survey Questions, Answered
A cold room raises different questions to a high energy bill, but property owners across South East England tend to ask us much the same things before booking a heat loss survey.
A Heat Loss Survey, sometimes called a house heat loss survey, uses thermal imaging to show where a property is losing heat, covering areas such as insulation gaps, cold bridging and draughts, so you know exactly where energy efficiency improvements will have the most impact.
An Energy Performance Certificate gives a modelled rating based on standard assumptions about a property's age and construction. A Heat Loss Survey is a physical, on-site inspection that shows exactly where a specific property is genuinely losing heat, which an EPC cannot do.
They use the same underlying technology, but a Heat Loss Survey is specifically focused on energy performance and retrofit planning, while a general thermal imaging survey can also be used to investigate damp or other suspected defects.
Yes. Accurate results depend on a reasonable temperature difference between inside and outside, generally at least ten degrees Celsius, held fairly steadily for the twenty-four hours beforehand. Surfaces need to be dry and shaded from direct sunlight for several hours prior to inspection, which is why most domestic surveys are booked for cooler months, early mornings or evenings rather than the middle of a sunny afternoon.
It is not compulsory, but it means any money spent on insulation or retrofit work is targeted at the areas that genuinely need it, rather than assumed based on the property's age alone.
Yes. It helps landlords understand a property's genuine thermal performance and plan energy efficiency upgrades sensibly, rather than reacting to tenant complaints or high bills after the fact.
Heat loss survey cost depends on the size of the property and the scope of the inspection required, whether you are asking about heat loss survey cost UK-wide or a thermal heat loss survey cost specifically. Contact us for a no-obligation quote based on your specific circumstances.
You receive a detailed report explaining the findings, along with prioritised recommendations arising from the survey.
