We design Battery Energy Storage Systems (BESS) for all property types, allowing households to store electricity from the grid at cheaper, greener rates.

Low-cost | Easy to Install | Cheaper energy | Reduces fossil fuel usage

What’s the current problem?

UK households are the largest greenhouse gas emitters in Europe.

The British Government has a legal commitment to reach Net Zero emissions by 2050 and cut emissions to 68% of 1990 levels by 2030. OTTO is committed to help reach this.

Our Solution

UK households are the largest greenhouse gas emitters in Europe.

OTTO offers a unique BESS (battery energy storage system) that is inexpensive and easy to install, currently designed specifically for UK homes. It can be installed anywhere in the property without the need for DNO permissions.

OTTO uses machine learning information to optimize charging and discharging, significantly reducing CO” emissions and energy costs for the installed property.

OTTO batteries reduce CO2 emissions and energy costs by over 30%, contributing to the UK’s Net Zero targets and improving energy efficiency in residential properties.

Who are we?

Founder and CEO Darryl Piper had the idea to bring an easily installed and affordable housing energy optimising solution to UK homes back in 2023. Since then, he has gathered investment to bring the idea to reality, with electronics and product design consultancies working to bring a proof-of-concept prototype to fruition. OTTO’s technology is currently patent pending.

Accolades include being shortlisted in Europe’s leading pitch competition for Planet Positive Businesses, The BE100 (part of Blue Earth Summit 2024).

“Our Mission is to empower households with sustainable and economical energy storage solutions to help those with the lowest incomes save on their energy bills..”

We are edging closer to our market ready product and will be beginning the pre-order process in Spring/Early Summer 2025.
