Your property brief
Power-Factor Correction
Relevant billing charges, poor power factor or changed electrical loads can justify investigation. Establish the actual measurements and tariff basis. Power-factor correction is not a universal energy-saving device and should not be sold from the electricity bill total alone.

What the service can include
The brief covers load information, electrical measurements, existing correction equipment and the proposed response. It identifies switching, protection, location and maintenance requirements. Harmonic conditions and equipment compatibility need consideration before a capacitor arrangement is selected.
We provide every service in our catalogue, including the individual services within each trade, for all sectors and locations listed on this website. Tell us what your property needs so we can agree the work, access and timing.
What to consider
Power factor describes the relationship between useful power and apparent demand. Correction can change reactive demand, but it does not automatically reduce the useful energy a process needs. Harmonics and changing loads can affect selection and require a suitable engineering assessment.
A closer look at the property brief.
The work starts with the property.Before we visit
Provide the property supply and billing information and ownership of the electrical installation. Identify shared loads and access to distribution equipment. Agree who can authorise surveys and any shutdown.
How we help
We establish the reason for correction and assess the installation. Findings define whether work is justified and what arrangement is suitable. Handover records equipment, operating checks and maintenance requirements, with the commercial assumptions retained.
What affects cost and timing
Measurement scope, correction duty, harmonic conditions and installation access affect cost. Electrical alterations and maintenance may be separate. Compare the expected tariff effect with the complete project rather than assume a generic saving.
Property and sector applications
Managing agents need responsibilities and approvals connected to the correct owner. Residential blocks need communal and individual areas distinguished. Retail and hospitality need work coordinated with customers and occupiers. Our complete service and project offering supports all sectors, with scope suited to the property and the people using it.
Local coverage
We cover Northumberland, Tyne and Wear, County Durham and Tees Valley, including Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees and Middlesbrough. View all locations.
For several properties, provide separate access and occupancy information. A remote owner can nominate a local representative while retaining a clear route for approving the work.
Frequently asked questions
Does correction always reduce energy consumption?
No. Its principal purpose concerns reactive demand and power factor, not every form of electricity use.
Can capacitors be added without measurement?
The load and power-quality conditions need assessment before selection.
Should existing correction equipment be maintained?
Yes. Include it in the appropriate equipment-care arrangements rather than assume it remains effective indefinitely.
Can correction be installed for one tenant?
Establish the supply boundary, ownership and measured requirement before defining the work.
