Lighting Upgrade Planning
When This Calculator Is Useful
The calculator is useful for shops, workshops, offices, kitchens, halls, outside lighting and any area where older halogen or fluorescent lighting is used for several hours a day.
It does not decide whether a fitting is suitable or whether extra wiring is needed. That still needs proper electrical assessment before installation.

Frequently Asked Questions
Straight answers before you book electrical work.
Is the LED lighting calculator a quote?
No. It is a running cost estimate only. The cost to install or replace lighting depends on the fittings, wiring, access and testing required.
What electricity price should I enter?
Use the pence per kWh figure from your current electricity tariff or bill. The default is only a starting point.
Can LED lights reduce electricity use?
Often yes. Savings depend on the wattage difference, number of fittings and how many hours the lights are used.
