What Our Clients Say

Client Feedback

If any company uses a large amount of electricity and wants to reduce costs and support the environment, I would recommend a Voltage Optimiser with Powerdown220.

Paul Turnbull, Managing Director Harrison Packaging

We sincerely appreciate the responsiveness and the way that you conduct business. We have recommended your company to others because of our satisfaction with your service.

Graham McKinley, Site Facilities and Service Engineer Kinnerton Confectionery

We are delighted to welcome Powerdown220 into our commercial family, with a deal that will span for the next three years. We have already started to see vast amounts of savings in our energy bills since the installation and look forward to this continuing.

Head of Commercial and Sponsorships Macclesfield FC

I didn't realise beforehand that this would be the biggest project of its kind in the UK, but that fact puts it all into perspective. Powerdown had a really robust plan to deliver over 1100 Mitchell & Butlers sites across the country.

Dale Fenton, Energy Manager Mitchell & Butlers

When I looked into the technology, it was a no-brainer. It offered a quick return on investment with continued savings going forward and completely fitted with our environmental strategy.
