LDSA (London District Surveyors' Association)
The LDSA provides the Local Authority Building Control (LABC) service for all Greater and Central London Boroughs. Our teams of surveyors and support staff are based at each of the 32 local authorities across London and the City of London Corporation.
We are employed by clients, architects, contractors and developers to provide the building control service for domestic, commercial and residential schemes across London. As a network of building control surveyors we can also introduce you to our LABC colleagues in each of our 12 regions. (View LDSA regional contacts.)
We are the only public sector building control provider in London and are chosen to work on the most prestigious schemes in the capital covering all sectors: education; retail; healthcare; offices; residential; industrial and public sector. (View our case studies for the Olympic Stadium and the Atlas Building.)
We also take care of our local builders and architects who are working on the homes of the residents who live in our boroughs. Our close links with the Federation of Master Builders, our affiliation to the LABC partner Authority Scheme and LABC’s unique Registered Construction Details mean that when homeowners work with us they can be assured of the best possible service.
