How can we help?
Renovation or new equipment can change what your electrical installation needs to support. Discuss your consumer unit and planned changes with CAS so the connections can be assessed together.
Work and considerations
- Consumer unit replacement or extension
- Additional circuits and connections
- Connections for electric cooking
- Provisions for new equipment
Useful for your enquiry
Tell us about the current supply and equipment you want to add. You can share a photograph of the consumer unit after first contact.
Will the whole consumer unit need replacing?
That depends on its condition and the planned changes. The installation needs to be assessed before the work is agreed.
