A tool for UK battery & solar installers

Turn your website into the reason people call you first.

Embed a live battery-savings calculator on your site in two minutes. Visitors see what a battery could actually save them — then contact you, not a lead broker.

Cheap half-hours Peak half-hours

Your calculator. Your leads. Your brand.

You already tell customers a battery can pay for itself. This gives them a number, on your site, before they've even called you.

Drop in one line of code

A single script tag and a <div> on any page — WordPress, Squarespace, a hand-built site, doesn't matter.

Branded to you

Your company name, phone number and accent colour. No mention of us anywhere on the widget.

Enquiries go straight to you

The "get a quote" button calls or emails you directly. We never see or resell the enquiry.

Prices that stay accurate

Pulls today's real Octopus Agile rates automatically, so the estimate isn't stuck on the day you installed it.

Captures the quiet browsers

Not everyone calls straight away. "Email me this" turns a visitor who isn't ready to talk yet into a named lead in your inbox.

No setup hassle

One monthly fee covers everything. No hidden charges, no license keys, no learning curve.

See it as your customer would

This is the same widget, running live, on a mock installer page. Try dragging the sliders.

Battery storage without the guesswork

Bright Spark Electrical has fitted battery systems across Greater Manchester since 2014. Not sure if it's worth it for your home? Try the calculator.

This demo pulls real Octopus Agile prices live from Octopus's public API when it loads successfully — that's the "Using today's live Agile prices" badge you'll see appear. The "Email me this estimate" button posts to /api/lead; on a deployed copy with an email provider configured, that lands straight in the installer's inbox.
