Established in 1996. Built around experience.
Technical Electrical Services Ltd (TES) is a family-owned and managed electrical contractor delivering commercial, industrial, air-conditioning, testing, lighting, security, renewable-energy and maintenance solutions across the South East.
More than 30 years in the industry
Since 1996, TES has developed long-term relationships with main contractors, facilities-management companies, commercial property teams, occupiers and organisations operating demanding environments. Our experience ranges from testing and remedial programmes to substantial refurbishment, infrastructure, lighting, security and specialist electrical projects.
We understand that commercial electrical work is about more than installing cables and equipment. Programme, access, isolations, coordination, RAMS, testing, certification, communication and a clean handover all matter.
Our experience includes pharmaceutical and technical environments, warehouses, offices, data-centre infrastructure, public-sector buildings, schools, industrial sites and managed property portfolios.
Practical, professional and commercially focused
TES aims to make electrical work straightforward for the people responsible for a building, project or property portfolio.
Competent delivery
Experienced electricians and project support working to the agreed scope, programme and site requirements.
Clear documentation
Inspection, testing, certification and project information provided as required for safe operation and handover.
Long-term relationships
We value repeat business and aim to become a dependable electrical partner rather than simply a one-off contractor.
A straightforward approach from survey to handover
Understand
Review the building, scope, existing installation, access, programme and constraints before work starts.
Deliver
Coordinate with clients, main contractors and other trades while keeping safety, quality and disruption under control.
Test & hand over
Complete inspection, testing, certification, labelling and relevant handover information so the installation can be operated and maintained.
Where our experience adds value
TES has worked across a broad range of environments where electrical reliability, safe access and coordination are important.
Commercial & Industrial
Offices, warehouses, industrial units, refurbishment projects, distribution systems and lighting upgrades.
Pharmaceutical & Technical
Operational environments where planning, documentation, coordination and careful working practices are essential.
Data & Communications
Power and containment for technical rooms and communications environments, including infrastructure supporting critical systems.
Public Sector & Education
Testing, maintenance, remedial and project work within public buildings and schools.
One experienced contractor across multiple electrical disciplines
Our service covers electrical installation, commercial air-conditioning installation, the electrical supplies and controls for air-conditioning systems, testing, lighting, solar, battery storage, EV charging, security infrastructure, cable management and containment, data infrastructure and maintenance. That means clients can coordinate fewer separate electrical contractors for related works.
Trusted, recognised and professionally accredited
Our accreditations and memberships demonstrate our commitment to competence, safety, quality and professional standards across commercial, industrial and renewable-energy work.
Certification and membership marks are displayed for TES and should be used only while the relevant certification or membership remains current and within its approved scope.
