The missing layer
Where connectivity becomes a development risk, we make it deliverable.
Most advisers stop at a desktop report. Most carriers recommend their own network. We combine independent commercial advice with the practical capability to design, procure and deliver the route.
02
Carrier-neutral delivery
New duct and fibre routes designed around the site—not one carrier’s footprint—with Code-enabled delivery capability where the project requires it.

Altnet network economics
Backhaul, transit, colocation and architecture reviews designed to remove recurring cost without trading away resilience or growth capacity.
Explore cost optimisation ↘For data centre developers
Know what is actually there before you commit.
A carrier’s sales map is not a delivery strategy. We establish which networks are genuinely reachable, where their routes run, what is shared beneath the surface and what it will cost to create resilient capacity.
Site & land due diligence
Early-stage screening of proposed sites, nearby network corridors, likely points of presence, access constraints and fibre-delivery risk.
Route & diversity assurance
Validation of common ducts, chambers, bridges, railway crossings, river crossings, carrier dependencies and other shared-risk points.
Carrier RFI / RFP
Structured engagement with Tier 1, regional and specialist networks for dark fibre, wavelength, Ethernet, IP transit and cloud connectivity.
Commercial & delivery strategy
Comparable pricing, construction options, lead-time analysis, contract negotiation and a clear route from investment approval to first light.
Carrier-neutral infrastructure
When the nearest carrier is not near enough.
Where existing networks cannot deliver the right route, price or diversity, we can structure a new shared connection to the site—designed to be open to multiple carriers rather than captive to one.

Design the neutral route
Route selection, duct strategy, fibre count, chambers, entry points, resilience and future expansion.
Secure the delivery path
Wayleaves, highway interfaces, stakeholder coordination, build scope and project-specific regulatory structure.
Build through proven teams
Delivery through Crosskit Limited and an established network of civil, fibre, splicing and testing contractors.
Keep the route open
Ownership, IRU, lease or transfer structures designed around the developer’s capital and operating model.
Independent by design.Advisory, carrier procurement and any proposed Crosskit build are separately scoped and transparently priced.
For altnets & network operators
Take recurring cost out of the network—without weakening it.
A confidential review of backhaul, transit, colocation and network architecture, backed by real carrier-market experience and practical implementation support.
Diagnose→Renegotiate→Replace→Verify savings
Arrange a confidential reviewBackhaul & EAD
On-net alternatives, dark fibre, wavelengths, contract expiry and route substitution.
Transit & interconnect
Commit levels, burst structures, peering, cross-connects and provider mix.
POP & colocation
Estate rationalisation, underused capacity, duplicated sites and data-centre costs.
Architecture & contracts
Commercial complexity, resilience gaps, supplier dependency and growth headroom.
Commercial model
Fixed diagnostic. Agreed implementation scope. Optional success fee linked to verified savings.
That keeps the work focused on measurable outcomes rather than a generic consulting day rate.
How we work
One accountable path from uncertainty to live service.
Discover
Site, power, programme, capacity, resilience and commercial objectives.
Verify
Networks, routes, shared risks, delivery constraints and realistic availability.
Procure
Carrier engagement, comparable bids, negotiation and recommended solution.
Deliver
Design, civils, fibre, testing, handover and operational acceptance.
Optimise
Costs, capacity, supplier performance and future route expansion.
We test the route beneath the product name.
The client’s outcome comes before carrier preference.
Recommendations must survive budgets, incidents and live operations.
We remain useful after the report is approved.
Built from operator experience
Advice shaped by building and running real fibre networks.
Cross Infrastructure is led by Antony Cross, a UK fibre network founder and operator with more than 16 years’ experience spanning network architecture, carrier procurement, civils, HSEQ, service operations and board-level infrastructure strategy.
The proposition brings together direct knowledge of UK backhaul markets, relationships across Tier 1 and regional networks, and an established delivery ecosystem of civil and fibre contractors.
Start early
Bring us in before the carrier shortlist is fixed.
A postcode, site boundary and target capacity are enough to begin an initial conversation.
