Survey FAQs

How much does a topographical survey cost?

Costs depend on site size and complexity. Small residential plots typically range from around £600–£1,200 + VAT; larger sites can be £1,500–£4,000+. Survey partners provide fixed quotes once scope is clear.

How long does a survey take?

A typical topographical or measured building survey for a single dwelling can be completed on site in one day, with drawings delivered within a few days to a week. Larger or drone surveys may need more processing time.

Do I need a survey before an extension?

Yes, in most cases. A measured building survey gives your architect accurate existing plans, elevations and sections; a topographical survey captures levels and features. 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 rich data quickly.
