Most commercial electrical contractors are middlemen — they sell the job, then send a labour-only subcontractor to deliver it. That works for the contractor's overhead, less so for your project. We work differently.
Dan Stevens is the director, the quoting engineer, the installing engineer and the signatory. No handover loss between sales and delivery. The face on site is the face you spoke to on the phone.
