Our engineers begin by undertaking initial liaisons with the Adopting Party, this gives us an idea of the projects current position and helps us ascertain the scope of required investigation works which will be required, this stage is usually free of charge.


Establish Scope of Works

The investigation work outlined in stage 1 is carried out to discover the extent of required adoption works and to ascertain the fixed fee cost to complete the full project. Our engineers provide a comprehensive adoption solution report with a guaranteed fixed fee cost to reach achieve adoption.

Completion of works

Following the client’s instruction, our engineer’s mange the completion of all required works identified in the Adoption Solution Report. We will then obtain written confirmation of satisfaction from the Adopting Party which confirms the project is acceptable for adoption.



Our team will submit an application to the Adopting Party and obtain formal certification to confirm adoption has taken place, which discharges the clients’ responsibilities and allowing cancellation of the associated bonds.


In order to help our clients avoid a backlog of adoption projects, JLES can be appointed as your ‘specialist contractor’ during the construction phase of the development. Not only can we support your technical team with securing technical approval, executing agreements or liaising with the adopting authority, but we offer ‘fixed cost’ quotations to act as your managing agent and contractor for the estate completion works.
