Thermal imaging roof survey in Belgravia, Greater London
We carry out thermal roof surveys in Belgravia and the rest of Greater London. Surveys run on any day of the week.
- Wet insulation beneath the membrane
- Gaps in loft insulation
- Ceilings that feel colder in places
Checking the roof from ground level
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
Thermal roof surveys for homes and businesses in Belgravia
Thermal imaging is often most useful on flat roofs, from small extensions to large commercial roofs. It can show patterns that point to trapped moisture under the membrane. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we combine the camera with an inspection from the loft where there is safe access. We survey commercial roofs, loft conversions and insulated roof spaces, and the problems we’re asked to look at most are areas losing heat at the eaves and junctions and water getting in at parapets and stacks.
London’s roofs are often hard to see from the street: valley gutters behind parapets, dormers and flat-roofed rear additions. That is where a view from the air or a thermal camera helps, by showing what cannot be reached safely. The weather decides the day: both drones and thermal cameras need the right conditions. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
How fast the report arrives depends on the package: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Why get it checked now?
For buyers, a thermal survey adds detail that a visual inspection cannot give. Hidden problems found before exchange can be raised with the seller or agent. Any roof job in Belgravia means planning around parking, neighbours and access. That’s a good reason to find problems early, while there is time to plan.
All our prices include VAT. Thermal roof survey starts from £400, including VAT. We confirm the price for the job before booking.

Useful tips for Belgravia property owners
Over many surveys, some simple habits stand out as worth the effort:
- Keep the heating on as usual before a heat loss survey
- Move stored items away from the loft hatch
- Check from the ground or a window, never by climbing
- Remember the conditions on the day affect the results
The report explains the conditions on the day and how they affected the images. It helps you judge how firm each finding is.
Have small defects in the covering fixed early. Once water gets under a membrane, it can travel far before it appears inside.

For landlords and managing agents
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait.
Businesses and commercial landlords can book us too, including offices, shops and units. Larger roofs take longer, and they’re priced for the size.
Common roof problems in Belgravia
On big commercial and residential flat roofs, thermal imaging helps owners plan. Patterns can point to wet areas and show which parts look sound, so we know where to take moisture readings.
Problems we come across frequently include:
- Areas losing heat at the eaves and junctions
- Stains that keep coming back
- Wet areas near outlets and upstands
- Possible trapped moisture under a flat roof covering
If you own one of the older houses in the streets near St Peter's Church, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.
Before booking any roof surveyor
- Their drone registration, if they fly one
- What the report includes, and whether it has photos
- Whether the price includes VAT

Drones, thermal imaging and Belgravia roofs
Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Older coverings on steep or tall roofs are hard to judge from below, so close-up aerial photos and thermal images help. The restricted area over Hyde Park, where drone flights need permission from NATS, is about 1 mile from Belgravia. Where the drone is part of the survey, we check whether the address falls inside it before flying.
Apsley House, about 0.4 miles north, is one of the historic houses in the wider area around Belgravia. A drone or thermal survey does not involve any work on the roof, which suits older buildings. If you look after a building such as Holy Trinity CofE Primary School, big roofs are where photos from the air and thermal images show the most at once.
Belgravia is about 1 mile south of City of Westminster, in Greater London. Wherever you are in Belgravia, we can carry out thermal roof surveys at your property, on a weekday, Saturday or Sunday. Belgravia is one of the towns and villages in Greater London where we work for thermal roof surveys.

What we do, step by step
On the day, we start by asking what you’ve noticed and what you want to find out. After that, we look at everything we can see safely, using the ground, windows, the loft and a drone where it applies. The survey typically takes about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. In a London conversion, the way into the roof space is often from a communal landing or the top flat. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Belgravia runs like any other.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- The roof is inspected visually from safe viewpoints.
- We take thermal images of the roof to pick up temperature patterns.
- Any patterns of interest are checked with moisture readings where we can reach them.
- You get a report with thermal images, photographs and our recommendations.
Preparing for the visit
- Let us know about parking near the property
- Keep pets out of the way during the survey
- Buyers: confirm access with the estate agent or seller

Advice
Common questions in Belgravia
Are there drone restrictions around Belgravia?
The answer turns on the exact location and the conditions on the day. The flight restriction zone around London Heliport in Battersea covers Belgravia, or comes right up to its edge. We ask the heliport for permission before flying there, and only fly if it’s given. The restricted area over Hyde Park, where drone flights need permission from NATS, is about 1 mile from Belgravia. We check whether the address falls inside it, and if it does we apply for permission, which isn’t always given. Across London there are restriction zones around Heathrow, London City and London Heliport, plus restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. The flight also waits for calm, dry weather, and the rest of the survey does not depend on the drone.
Is parking a problem for a survey in Belgravia?
It can be, so it helps to let us know about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Which survey includes thermal imaging?
Our Premium Survey, from £400, includes thermal imaging. An in-person consultation and a follow-up 12 months later are included too. Larger commercial roofs are quoted for their size.
How many surveys have you done?
Over 20 years and more than 5,000 surveys.
Can you check my loft insulation with a thermal camera?
The camera can point to heat loss and gaps in insulation. We don’t give energy ratings or heat loss calculations, but the report shows where to look more closely.
Are you structural engineers?
No. We point out what can be seen, such as sagging or deflection, but we are not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
Does this replace a RICS home survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
