Drone surveys for heritage buildings
Non-invasive aerial surveys protecting and documenting listed buildings, scheduled monuments, churches, cathedrals and historic structures — entirely without scaffolding or physical contact.
Short answer
Image Surveys Limited (CAA Operator ID GBR-OP-K3GKP2JCP5DJ) works with heritage property owners, conservation architects, local authorities, charities and trusts who need detailed, non-invasive surveys of listed buildings and historic structures across the North West. Surveys support Historic England and NLHF grant applications, conservation management plans and ongoing stewardship of irreplaceable buildings.
Drone surveys are ideal for heritage work because they are entirely non-contact — no scaffolding, no drilling, no fixings, and no physical contact with the historic fabric whatsoever. Towers, parapets, nave roofs and high-level masonry that are inaccessible without specialist access equipment can be surveyed in a single visit. Leaf-off capture between November and March gives the cleanest record of stonework and roof structure.
Who we work with
- Listed building owners and trustees
- Conservation architects and surveyors
- Historic England grant applicants
- National Lottery Heritage Fund applicants
- Churches, cathedrals and ecclesiastical property owners
- Local authorities and conservation officers
- Museums, heritage trusts and amenity societies
Problems we solve
- Inspecting roofs, towers, parapets and high-level masonry on listed buildings without scaffolding or any contact with the historic fabric
- Producing condition reports and photographic records to support Historic England and NLHF grant bids
- Recording historic structures before, during and after conservation works
- Identifying moisture ingress, vegetation growth and stone deterioration at height
- Creating accurate measured surveys and 3D models of complex historic structures for conservation architects
- Monitoring structural movement and deterioration over time without disturbing the building fabric
Case study
Cheshire
Grade I Listed Church Survey for Heritage Fund Bid
A charitable trust managing a Grade I listed church required a detailed condition report and photogrammetric record as part of a £1.2 million National Lottery Heritage Fund application. The building's tower and nave roof were inaccessible without specialist access equipment — but physical contact with the historic fabric was not permissible.
Frequently asked questions
Can drone surveys be used on Grade I or Grade II listed buildings?
Yes. Drone surveys are particularly suited to listed buildings precisely because they are non-invasive — no physical contact, no fixings, no scaffolding. Many listed building consent conditions specifically prohibit physical contact with historic fabric; drone survey is often the only practical method of inspection at height.
Will Historic England or the NLHF accept drone survey evidence?
Yes. We have produced condition records and photogrammetric evidence that have been accepted by the NLHF as part of formal grant applications. We produce all records to a standard appropriate for submission to statutory bodies and funding organisations.
What is the best time of year to survey a historic building?
Leaf-off conditions between November and March give the clearest record of stonework, roof structure, parapets and towers, as vegetation does not obscure elevations. We can survey year-round, but recommend leaf-off timing where the survey will form part of a formal condition record or grant submission.
