Wiltech Acoustics — now proudly part of Rehlko (formerly Kohler Energy) — is entering an exciting phase of growth and investment. Now integrated into Rehlko’s global energy-resilience group, Wiltech continues to build on its reputation as a leading UK specialist in acoustic canopies, generator enclosures, and industrial noise-control engineering.
Based in Loughborough, our manufacturing facility handles everything in-house — from raw material processing to welding, fabrication, painting, and full assembly of bespoke acoustic units. Joining Wiltech now means becoming part of a strengthened, well-funded and expanding organisation, with new opportunities created through the Rehlko transition.
