Why Choose ENWCML?
Reduce Costs, Enhance Efficiency
What is PFC?
Power Factor Correction (PFC) aims to improve power factor, and therefore power quality. It reduces the load on the electrical distribution system, increases energy efficiency and reduces electricity costs. It also decreases the likelihood of instability and failure of equipment. Power factor correction is obtained via the connection of capacitors which produce reactive energy in opposition to the energy absorbed by loads such as motors, locally close to the load. This improves the power factor from the point where the reactive power source is connected, preventing the unnecessary circulation of
current in the network.
An electrical network operating at unity Power Factor represents a system at 100% efficiency. Anything less than unity means that extra power is required to achieve the actual task at hand. Power Factor Correction (PFC) is the term given to a technology that is used to restore Power Factor to as close to unity as possible and is normally achieved by the installation of capacitors (occasionally inductors) to the electrical network.
Reactive power charges can be eliminated to provide instant savings for the energy consumer. Power Factor Correction equipment should be serviced at least once per year to ensure that the capacitors within are still producing 100%. This ensures that you maintain those reactive power charge savings.
Annual Servicing – Protects Investment & Savings
To ensure you continually make the potential savings on reactive power and availability charges, it is essential that any installed power factor correction equipment is serviced at least once every year.
Capacitors can deteriorate over time; the dielectric inside breaks down based on the number of occasions they are switched, the amount of time they are in operation and the number of external events they’re subjected to. It is therefore essential to consistently check the health of your PFC equipment, enabling it to continue to operate at an efficient power factor (>0.95) – the point at which charges will start to
be captured on your electricity bills.
PFC servicing can be added to your existing COMA, spreading the cost over the term of the contract and removing the management overhead of scheduling, as we will tie this into our inspection regime for the site.
Power factor basics principles:
Poor power factor (for example, less than 95%) results in more current being required for the same amount of work. PFC corrects this aims to achieve unity power, saving energy for your site.

In-depth inspection of your property’s electrical systems and installation
Electrical Inspection Condition Report (EICR)
ENWCML can include your EICR as part of your COMA agreement, where we are already providing LV Maintenance services. Embedding these services, takes away any worries about site compliance and you can spread the cost of the service over the term of the agreement.
Please contact our team for a survey and initial estimate.
What is EICR?
An electrical inspection condition report (EICR) is an in-depth inspection of your property’s electrical systems and installation. The report assesses the competency of your electrics by three different categories:
How do you know if you need an EICR?
Over time, electrical installations will deteriorate with wear and age. This can potentially become a risk if they are not regularly checked; improperly insulated wiring can lead to dangerous electrical shorts while faulty wiring and appliances can cause electrical fires. So, whether you’re a business owner, landlord or homeowner, it’s important you carry out regular checks on the condition of the electrics in your property. The IET Wiring Regulations BS 7671, which sets the standard for electrical installations in the UK, recommends the following:
What is the aim of an electrical installation condition report?
The five main aims of an electrical installation condition report are:
- 1
Record the results of the inspection and testing to make sure the electrical installation is safe to be used until the next inspection (following any work needed to make it safe)
- 2
Find any damage and wear and tear that might affect safety, and report it
- 3
Find any parts of the electrical installation that do not meet the IET Wiring Regulations
- 4
Help find anything that may cause electric shocks and high temperatures
- 5
Provide an important record of the installation at the time of the inspection, and for inspection testing in the future.

Thermal Imaging
Thermal window installation to new or existing LV panels. We can install new LV panels with Infrared windows to allow non-intrusive thermal imaging surveys at any site. Equally, where possible, we can retrofit a solution to an existing panel

Thermal Imaging
Thermal Imaging is an annual component of our LV Maintenance service, and allows our engineers to identify temperature anomalies that may indicate a loose, over-tightened or corroded connection, or damaged/ under sized wires for the loads they are under.
The way we conduct thermal imaging is changing from 2023. Read below to find out about the new changes we have introduced for our LV maintenance customers, and what your options are for thermal imaging moving forward.
A new, safer thermal imaging approach from 2023
We recognise that thermal imaging is an excellent and cost-effective way of finding potential problem areas before they cause a fault and is often required be insurance companies.
Following a number of HSE notifications of injury and damage caused by thermal imaging when carried out live by the removal of panel covers (See HSE Article), ENWCML will no longer carry out thermal imaging this way, and has now rolled out a new approach that better protects the safety of our engineers and the equipment they are imaging.
Whilst we explore other options below, our preferred thermal imaging solution is the installation of thermal windows, because of their effectiveness and reliability, and the significantly improved safety they afford.

At Half The Cost
Thermal Window Installation
As such ENWCML have worked with a UK panel manufacture, creating a new design of thermal window (also known as an Infrared Window or IR Window), which can be installed to the majority of LV panels.
This initiative is driven by safety improvements and the window is a proven method of conducting safe imaging, installed to the front, back and side of panels at connection points and key areas.
ENWCML have invested in this product to ensure affordability for our customers and, compared to generic thermal windows, the ENWCML product will typically be installed at half the cost of comparable market leading alternatives.
Your Options for Thermal Imaging
Thermal window installation
As noted above, thermal windows are an effective, reliable, and safety-first improvement for thermal imaging, and the option we would like to encourage moving forward. We would like to offer both our existing customers, and new customers, an onsite survey of your LV panel, and provide a quotation to install thermal windows at a convenient time.
Exterior thermal imaging only
We can continue to conduct the thermal imaging to the exterior of the LV panel, utilising a method to calculate the perceived heat within the panel. All customers without thermal windows will automatically be moved to this option for the safety of your equipment and our engineers. However, this is a less accurate method of measurement as individual hotspots are not isolated within the measured data.
Power isolation
If there is no IR window in place, we can conduct the survey for thermal imaging only once the power is isolated to the panel. Our engineers will then remove the panel covers to complete the works in safety. This option will provide reliable measurements, but will result in downtime for all future testing at the site as we can no longer remove panels on live switchgear following the HSE guidelines.
