Good electrical work starts with doing things properly.
NOD Electrical Services is a Streatham-based, NAPIT Approved Contractor working with homeowners, landlords, property managers and businesses across South London.
Founded by Nick O'Donnell, the business combines traditional electrical training with practical planning, clear advice and workmanship we stand behind. We explain what work is needed, why it matters and what it involves before getting started.
Meet Nick O'Donnell
My electrical career began with a four-year industrial apprenticeship. I later spent many years in senior commercial roles in the fashion industry before returning to electrical contracting and building NOD Electrical Services.
That combination shapes the way we work today: technical competence matters, but so do communication, attention to detail and respect for the people and properties we work with.
From a small repair to a complex installation, we aim to explain the options clearly and deliver a safe, tidy and considered result.
“The standard of work we deliver should be something I would be happy with in my own home.”Nick O'Donnell · NOD Electrical Services
