Planning & Development
What survey do I need for planning permission?
Most planning applications need an up-to-date topographical survey of the site and often a measured building survey of any existing structures you plan to alter. Boundary surveys may be required where works are close to the property line.

Yes, in most cases. A measured building survey gives your architect accurate floor plans, elevations and sections; a topographical survey captures levels and features in the garden. Together they reduce design risk.

When should I use a drone survey?
Drone surveys are ideal for large or inaccessible sites, roof inspections, progress monitoring and volume calculations. They often cost less than traditional surveys for big areas and deliver orthophotos, contours and 3D models.

Utility surveys locate and map buried services (electric, gas, water, telecoms, drainage) before excavation. They reduce the risk of service strikes and support CDM and design. Often combined with topographical surveys.
