PFC Testing
Professional PFC Testing Across the UK
Electrical Testing UK carries out power factor correction (PFC) assessments for commercial and industrial operators to identify inefficient electrical usage and its impact on cost and capacity.
Our engineers measure power factor under load, assess the financial impact, and recommend correction equipment where improvements will reduce costs and improve supply efficiency.
How Our Service Works
Power Factor Measurement
We measure actual power factor under real operating load conditions to provide accurate baseline data.
Financial Impact Analysis
We calculate the cost impact of poor power factor on energy use and demand charges to show the financial case for correction.
Correction Equipment Specification
Where needed, we specify the correct type and rating of power factor correction equipment for your installation and load profile.
Supply and Installation
We supply, install, and commission power factor correction equipment, verifying performance against the original baseline.
Ongoing Monitoring Available
We offer post-installation monitoring to ensure power factor remains at the target level.
PFC Testing for Commercial and Industrial Sites
Power factor correction assessments identify inefficient electrical usage in industrial and commercial sites and determine whether correction will reduce costs or increase available capacity.
- Manufacturing and industrial sites: Measure power factor at supply and load points, analyse operational conditions, and specify correctly sized correction equipment for inductive loads
- Commercial premises: Assess offices, retail, hotels, and similar buildings to determine whether correction will reduce demand charges and improve efficiency
- Equipment supply and installation: Provide and install automatic correction panels that maintain target power factor, with commissioning and verification by qualified engineers
- Load expansion planning: Assess whether improving power factor can free supply capacity for new equipment, EV charging, or HVAC without a costly supply upgrade
PFC Testing: FAQs
How is power factor measured under operational conditions?
We install monitoring equipment at the incoming supply to measure power factor, active, reactive, and apparent power over at least seven days to capture full load variation.
How are results analysed and correction equipment specified?
Monitoring data is used to assess reactive demand and power factor trends, calculate financial impact, and specify correctly rated correction equipment to achieve the target performance.
How is correction equipment installed and commissioned?
Equipment is installed at the main distribution board or load points by qualified engineers to BS 7671, then commissioned and tested to confirm performance and achieved savings.
Why Organisations Choose Our PFC Testing
- Measurement before recommendation: We measure actual power factor first and only recommend correction where data supports it
- Honest financial analysis: Savings are calculated using your real tariff, metering, and load profile, not estimates
- End-to-end service: We assess, specify, supply, install, and commission under one contract with a single point of contact
- Qualified in-house engineers: All work is carried out by NICEIC-qualified engineers, with no subcontracting and full accountability
