Pros

Good mission and purpose. Flexible working. Talented and supportive colleagues at the mid and junior levels.

Cons

OVO was never perfect and a level of change was expected with a new CTO. But what we are seeing now is not positive change, it is destructive. The CTO leads with aggression, control and exclusion. He shouts, swears in public meetings, and uses phrases like “Get it done!” or “This is a must!” which only create fear. There is no collaboration, no bringing people on the journey. He has brought in a large number of expensive consultants, many with no understanding of OVO, the energy industry, or how the company operates. They apply a cookie-cutter approach and add very little value. Some are flown in from the US at a moment’s notice, burning through huge amounts of budget, even while the rest of the company is under heavy cost pressure. Worse still, several of these consultants are embedded in the tech leadership team itself. They are now driving decisions, despite having no context, no connection to the people, and no real clue about the business. Their input is full of corporate jargon and generic slides, which only adds to the disconnect between leadership and the rest of the organisation. The culture has shifted dramatically, from one of trust and autonomy to fear and control. People are scared to speak up. Town halls are staged. Feedback is ignored. The People team is complicit, more focused on pushing people out than addressing what is really happening.

Pros

Really caring, competent staff on the ground level that actually care about OVOs customers.

Cons

CTO needs to go. Backhanded deals with suppliers, tech wide emails that have to be removed from the system, shouting at colleagues in meetings. I understand it's scary to stand up to a bully but by not doing this the wider Leadership team are condoning this behaviour. If this continues, I can't see OVO surviving unless they move everything offshore.

Let this be a warning to anyone hiring Guy Duncan in future

Pros

Benefits and community were always great, but thanks to the CTO and his suck—up cronies there’s no chance of OVO regaining a Top UK Employer accolade again any time soon.

Cons

How do you go from a too uk employer to the gutter in less than a year? Read on. Since joining as CTO, presumably as a joke parting gift by Raman Bhatia on his way out the door, Guy Duncan has destroyed all credibility, trust, craft, respect, humanity and psychological safety in the tech and product community. I can hardly find the words to describe just how bad things have got so quickly at the hands of a wanton narcissist with zero skill, expertise or empathy. You can claim to justify huge layoffs as a cost cutting measure, but they don’t even say that. They’re forcing out all skilled management in place of over-stretched general support managers on a laughably low salary. They’re sitting back and watching most other skilled individuals with a shred of self respect happily walk out the door than stick around for more foulmouthed tirades from the notorious Guy Duncan. A VP is wheeled out to present a future vision of the new structure, but can’t explain it, can’t justify it, can’t add any credibility to it and dodges all questions that have a hint of challenge. I’m surprised she didn’t just delegate it to one of the many consultants she’s helped to bring in from her former employer. OVO is burning through money on contracts and hires of the CTOs friends and investments, where flying to and from the US and Eastern Europe and hosting 5* offsite, but there’s no promotions or training budgets for normal people for over a year because there’s “nothing left in the budget”. A certain director/c-level has managed to get more wistleblowing reports against him in a couple of years than anyone else ever has at OVO, but instead of being sanctioned or dismissed, he gets promoted by the CTO as reward for sucking up and throwing his own teams under the bus. It’s sickening. The leadership team should be ashamed and I hope their future potential employers look back on these reviews and save themselves a train wreck.
