Our Services:


Fixed Wire Testing is a mandatory requirement for all commercial and industrial premises. All electrical installations suffer damage and deterioration throughout their operational life, which makes these tests essential in confirming the safe operation of the installation.

Often seen as a complex and expensive problem or “dark art” by managers and business owners, CES works to make this essential process straightforward and transparent for its customers and partners.

CES has a structured and unique approach to managing Fixed Wire Testing. Our aim is to proactively give the customer sufficient information to enable them to minimise disruption during testing and remedial maintenance.


A Thermographic Survey enables you to detect electrical faults before the components fail. This is a non-intrusive, proactive and efficient method of supplementing your planned preventative maintenance regime. And because it’s non-intrusive, it’s fast and efficient.

At CES we use the latest industry-leading cameras and software to produce high-precision reports that clearly identify any problems so you can take immediate action without all the added disruption of invasive exploration.

All our Thermographers are trained to ensure that images are interpreted correctly and thoroughly. We provide detailed online reports which highlight any potential defects, enabling the correct investigation and repairs to be carried out.


During the Fixed Wire Testing process, our engineers highlight areas which are not conforming to the IEE Wiring Regulations. These are coded in order of severity and compiled into a comprehensive Electrical Installation Condition Report (EICR).

As an accredited NICEIC Approved Contractor, we are able to carry out the necessary remedial repair works to get your Electrical Installation up to compliance.


Installation testing is only part of the electrical safety compliance requirement. It is essential that remedial work is completed following testing to ensure due diligence.

When electrical safety testing is completed anything recorded as damage, deterioration, defect and or dangerous within the installation will be reported as follows:

  • FI – Further investigation required without delay.
  • Code 1 – Risk of injury. Immediate remedial action required.
  • Code 2 – Potentially dangerous and should be given urgent attention.
  • Code 3 – Improvement recommended.

Any fault reported as FI, Code 1 or 2 must be remedied.

Essential remedial work must be resolved in an appropriate time frame.

All required remedial works identified whilst testing will be detailed within CES reports. Sign off sheets are formally issued to provide closure of defects which also enables traceability to each defect.


It is vital that your Emergency Lighting is reliable and regularly tested and maintained to ensure compliance with BS 5266-1:2011 and the Regulatory Reform (Fire Safety) Order 2005.

Types of Electric Vehicle Charging Point

There are 3 main types of EV Charging Point. Rapid, Fast and Slow.

Rapid or Super Chargers are mainly found at Motorway Services and other public locations where super-fast charging is necessary during a journey. A typical example is Telsa Super Chargers which can charge the vehicle up to 80% in just 20 minutes.

Fast Chargers are the standard for home charging and workplace charging, they can be installed at homes, businesses and other public locations to enable users to charge their vehicles within only few hours, depending on the vehicle and rating of the charging point. The most common fast charger we install is rated at 7kW which will charge most vehicles from 0-100% within 6-8 hours.

Slow chargers (or trickle chargers) are generally only for emergency charging and can take 12 hours or more to charge the vehicle, they tend to be designed to charge form a normal 13A plug socket and are often not designed to be used day in and day out as it can cause overload to the sockets in your house.

What Different EV Charging Plugs/Connectors are Available?

There are two main types of plug that are commonly used: Type 1 & Type 2
Type 2 plugs are the most commonly used and we believe the best option, but the type of plug you use depends which vehicle you have
Both types of plug can charge up to 32 amps but the type 2 plug also allows for 3 phase charging if your installation has this option. This enables faster charging in some situations.
