About Electrical Maintenance


Electrical maintenance is an essential part of any business. Electrical installations, like most things, degrade over time. Switches and sockets can sustain damage, cables, deteriorate and infrastructure/connections can also become loose. Degradation is even more apparent in installations where adverse elements are involved. i.e. corrosive chemicals, construction waste, high usage or poor maintenance on the part of tenants or landlords.


The implications of an unexpected breakdown or failure can be extremely costly, not only with regards to the cost of repair or replacement of your machinery etc., but also the cost of possible downtime to your business. CWE have established themselves as the longest serving electrical contractor in Wolverhampton, we are able to provide service solutions tailored to the client’s needs. Through a planned maintenance programme, CWE can ensure that your installations are fully compliant and up to date with the latest regulations, leaving you to concentrate on your business.


In any environment there is always a risk of component failure and therefore maintenance is a must for most companies. At CWE we provide a 24hours a day, 7days a week, 365days a year emergency callout service.

About Electrical Installation

CWE is an approved commercial electrical contractor with the NICEIC. We only work within the commercial and industrial sectors and are able to offer a full design and build service for the installation of all aspects of electrical distribution and lighting. Our services are carried out by highly qualified electricians and always to BS7671, the current British standards. 


We can install total power solutions for entire buildings, including back-up generation and UPS systems, full power installation utilising service outlets.


We specialise in industrial electrical tasks such as the standardisation of 3 phase wiring making sure your system meets current safety standards or installing inverters to convert a single phase supply into a three phase supply.


About Data Installation


From the installation of a single outlet to a complete network system, upgrading or maintaining your network, CWE are highly experienced in all types of data system wiring installations.


Structured cabling allows the majority of today’s Data networks to be distributed over a single infrastructure. With the arrival of IP Communications, it is more vital now than ever that you have a platform which all of your applications can be built upon. The heart of your IT system is the cabling infrastructure, this is the backbone that holds the whole system together. If the infrastructure is not up to a high standard, data may flow at a slower rate, information may get corrupted or lost and in worst case scenarios, applications will simply not work.


An advantage of using Cat 5 and Cat 6 cabling is its ability to be connected to the phone line. Both Cat 5 and Cat 6 adhere to a much higher quality than that of ordinary telephone cables and offer a much higher quality of signal.


We can design and install bespoke patch panels and data rack cabinets – with all installations tested, commissioned and certified upon completion. Working together with leading manufacturers including; MK, Philips and Newlec, to provide all clients with the best service and products possible.

Instructing CWE to manage your data installations, as well as the electrical installations, will prove both financially and logistically beneficial. Where required, we can work alongside nominated computer or telephone suppliers to ensure a thorough understanding and a professional level of co-operation exists, to enable the installation to proceed to a smooth completion. We will ensure that the installation is completed in budget and on time with minimum disruption.

Data types include:

  • Cat 5E UTP/FTP/STP
  • Cat 6 UTP/STP
  • Cat 7 STP
  • Coax
  • Fibre Optic

Once an access control system is installed, all entry points controlled by the system will automatically lock when the door is closed. Anyone without a PIN or access fob is unable to enter. Various levels of access can be set up allowing all staff to gain access through the main doors but to restrict access to internal areas unless there is a specific need to be there.
