The short answer
The written scope should state who is responsible for confirming isolation or disconnection of electricity, gas, water, telecoms and any other relevant services. Services can be concealed, still live or shared with neighbouring properties. Clear written responsibility prevents unsafe assumptions and avoids delays once work is due to start.
Why it matters
Live services in a demolition or strip-out area are a safety risk and a programme risk. Utility providers have their own processes and lead times. Identifying service responsibilities at the quotation stage — rather than on the day work is due to start — allows the programme to be planned around confirmed isolation.
Information that may be needed
Service drawings, meter information, utility correspondence and records of confirmed isolation may be relevant. Where services are shared with neighbouring properties, the position should be confirmed with the relevant provider before work begins.
What can affect the scope
The property type, work area, retained services, utility-provider process and programme can affect what is required. Some disconnections require the provider to attend site; others can be confirmed by the client or a competent specialist.
When specialist input may be needed
A utility provider, competent electrician, gas safe registered engineer or other qualified specialist may be required depending on the service. Some disconnections can only be carried out by the network operator.
