The electrician calculator for your website
Your customer puts together a new consumer unit, an EV charger or a lighting and socket plan, and sees an estimate right away. You get an enquiry with everything in it: what they want, what comes with it and where it goes.

This is a demo company’s calculator. You set your own services and prices.
What your customer configures
- A new consumer unit: old one out, 8 to 24 circuits, single or three phase, RCBO per circuit
- Extra circuits, with the cooking circuit question for induction
- An EV charger: smart or basic, wall or post, cable and groundwork
- A lighting and socket plan per floor and for the garden, with smoke alarms
- No price until the customer chooses, then a range: an estimate, not a quote
- In your own colours and logo, and the enquiry lands in your dashboard
