Electrical Contractors for Commercial Projects & Air Conditioning
TES delivers electrical installation, testing, lighting, containment, security, renewable-energy and maintenance services for commercial and industrial properties across Hertfordshire, Bedfordshire, Buckinghamshire, London and the wider South East.
From electrical infrastructure to ongoing maintenance
We work with building owners, main contractors, facilities-management companies and occupiers to deliver electrical works in live commercial environments. Our experience covers offices, warehouses, pharmaceutical facilities, data environments, public-sector buildings, education sites and industrial premises.
Projects can involve a distribution-board or lighting upgrade, a refurbishment programme, a new electrical installation, specialist security infrastructure or ongoing planned and reactive maintenance. TES can provide one point of contact across multiple electrical disciplines.
Commercial electrical work with the practical details covered
Good commercial electrical work is about coordination as much as installation. TES considers access, shutdowns, sequencing, containment routes, segregation, testing, certification and handover as part of the project rather than an afterthought.
Project coordination
Work with clients, main contractors, FM teams and other trades to coordinate electrical activities around the programme.
Live environments
Plan isolations and access carefully where offices, warehouses, pharmaceutical premises or other buildings remain operational.
Handover
Inspection, testing, certification, labelling and relevant project information to support the building after completion.
