An independent network design authority.
Chroma Networks exists because the hardest telecoms estates deserve design work that survives contact with assurance, contractors and time. The practice was built inside rail, metro and mission-critical London telecoms, where a drawing either constructs cleanly or costs a possession.
We are a design authority, not a body shop. Every engagement is led by a senior design authority who remains accountable from survey to as-built, and every number in the pack is one we will defend at sign-off.
Behind that lead sits a vetted network of associate specialists across survey, civils, transmission, IP and geospatial data. Teams are assembled to fit the assignment, and every associate works to the same design rules, review gates and documentation standards, so the pack reads as one practice.
The practice also writes software. The same design rules we apply by hand are encoded into IQGeo, QGIS and bespoke tooling, so quality is repeatable rather than heroic.
One accountable authority per engagement.
Delivery scales through the associate network. Accountability never does.
Chroma Networks is an independent optical and transmission network design consultancy for rail, metro and mission-critical urban telecoms. We carry designs from survey through IHLD, HLD and LLD to as-built, pairing DWDM, OTN and SDH transport engineering with expert IQGeo and QGIS tooling and design-rule automation. The practice draws on 25 years across LU Connect, the Elizabeth line and TfL Connected London. Our packs are buildable as drawn, our advice is vendor-neutral, and our Connected London LLD packs were approved first time.
Credentials the work stands on.
The full register of licences, standards and certifications, and what each one protects for a client, is on the standards and compliance page.
Four ways to engage.
Design authority
Owner-side or integrator-side authority for transmission and fibre design, with assurance-ready documentation.
Detailed design
Survey to as-built delivery of LLD packs, splice packs, BoMs and SLDs that construct as drawn.
Assurance & audit
Independent review of designs, margins and data quality before they reach an assurance panel or a contractor.
Tooling & automation
IQGeo and QGIS configuration, rules engines and data QA pipelines built for your design office.
Bring us in at survey, not at rework.
A 30-minute technical call to pressure-test route, reach and margins before anything is committed to civils.
