Powering Switching Across UK Telecoms
Switching customers between providers is now a legal requirement under Ofcom rules — and getting it right is complex. CSP runs that switching for you. From residential One Touch Switching to business GPL-B compliance, we handle the infrastructure so you stay compliant and win customers.

FAQ
Common Questions
Pick your area to see the most relevant answers.
What is One Touch Switching (OTS)?
One Touch Switching is Ofcom's mandatory process for residential broadband and landline switching. The customer only contacts the provider they're moving to, and everything else is handled for them.
What does "Full Management MAP" mean for us?
We handle the TOTSCo hub connection entirely on your behalf. You don't build or maintain anything.
How long does it take to go live with OTS?
Usually a few weeks instead of months since the infrastructure is already built.
Does CSP handle number porting?
Yes, number porting is fully included in the switching flow.
What if a customer raises a complaint mid-switch?
The system supports pause, cancel, and correction flows with full audit tracking.
Do we need our own Ofcom licence?
You remain the provider of record, but we handle hub integration.
What is GPL-B?
Ofcom's business switching process where the gaining provider manages the switch.
How is business switching different?
It uses CSF instead of the residential OTS flow.
Why is CSP cheaper than building our own system?
You share infrastructure costs instead of building your own hub integration.
When can we start using business switching?
Availability depends on rollout stage — contact us for current timelines.
What's the difference between CSP and CWP?
CSP handles switching. CWP handles wholesale network access trading.
What is the wholesale marketplace?
A platform to list, find, and order network access.
What is BDUK compliance?
Government standards for gigabit broadband rollout funding.
Can we use CSP and CWP together?
Yes — many providers use both for end-to-end operations.
