The 24.5p figure is only an example so the form is ready to try. Replace it with the unit rate on your own tariff. Standing charges are not included.
Nameplate watts are often higher than the power a device actually draws. For a true figure, use a measured load. This is not a quote for supply or for an installation.
These tools are quick guides for a ballpark figure. They are not certified design or test software, and a result on this page is not a design, a certificate, or a substitute for the current edition of BS 7671. Check the working and cross-reference it before you apply it to a real installation. Thanet Electrical Ltd does not accept liability for loss or cost arising from reliance on these figures, except where the law does not allow that liability to be excluded, including death or personal injury caused by negligence.
