This is us

We’re powered by passion, guided by purpose, and driven to make a real difference for people and our planet.

Who we are

Energy’s changing. So are we. At Sero, we’re transforming the future of energy, one green upgrade at a time. No Jargon. No fossil fuel fluff. No one left behind. It’s power with purpose, so you can enjoy a home that’s cheaper to run and kinder to the planet.

Sero started in 2017 from a kitchen table in Newport, South Wales, with one simple goal: to help make homes better for people and the planet. Today, we still believe every home upgraded helps shape a greener, fairer future. We partner with some of the UK’s largest social housing landlords to upgrade homes with smart green technology, including solar panels and a battery, so it runs more efficiently and costs less to power. You don’t need to be an expert in energy. We’ve got that covered.

Based in Cardiff and proud to be a certified BCorp, (which means we’re doing good stuff your nan (and ours) would approve of!). We bring together smart ideas, expert knowledge, and great service to make Net Zero homes possible for everyone.

Net Zero homes, simply and affordably

👆🏼 Thats our mission. We’re here to make Net Zero happen across the housing sector at scale. It’s not just about green technology, it’s about people, experience, and how we pay for it. If it’s not simple and affordable for both landlords and residents, it just won’t work. We believe getting through the front door, in person and in the numbers is the key to unlocking Net Zero for everyone.

 

Our non-negotiables

At Sero, our values (our non-negotiables!) are more than just words; they guide everything we do, from technology decisions to doorstep chats.

People first: Putting people first, always.
Integrity: Doing the right thing, not the easy thing.
Innovation: Solving tomorrow’s problems, today.
Committed: We get the job done well.
Sustainability: Dream green and raise the bar.

Meet our team

Fuchsia Wildgoose

Zero Carbon Project Coordinator

Fuchsia’s happy place would either be wandering around Westonbirt Arboretum in the Spring, or watching live music surrounded by my friends 😊

Katie Wiliams

Creative Lead

Katie loves nothing better than trekking up the Sugar Loaf mountain with the family to indulge in the breathtaking views of the Monmouthshire valley… (also nothing to do with the vineyard conveniently placed at the foot of the mountain!)

Mick Ashley

Program Manager

Mick loves being in the great outdoors, whether it’s out on the hills in the lake district, dressed in spandex and exploring on the road bike or pottering in the garden, he is happy! The addition of a cold cider and his wife make it all the more better!

Tiago Ferreira

Product Owner

Tiago is happiest when he puts on a dinner jacket and joins Orchestras around Wales and England on stage playing the clarinet. When not performing, you’ll most likely find him dancing salsa in Latin parties!

Lizzy Wood

Marketing Manager

When Lizzy isn’t being kept busy by her son, you’ll find her cold water dipping in the sea, at the gym, or visiting her place of calm – New Quay, in West Wales.

Simon Morris

Manual Test Engineer

Attending the UKGamesExpo with his daughter, where he plays non-traditional board games and role playing game systems he has not experienced before. Especially loves those that he can bring back to play at home with his family and friends or bring to his local gaming group (as well as stories from the expo).

Rhys Thomas

Business Development Manager

Rhys loves nothing more than going home to help out on his family farm, it’s only 15 minutes from where he lives now but is definitely his favourite place. After that it would be Italy, especially the Amalfi Coast, simply stunning even if their roads are terrifying.

David Easton

Product Manager / Owner

Dave connects business and tech, helping teams focus on what matters and deliver value quickly. With 20+ years across the tech industry, science, media and more, he’s a true all-rounder.

Tom WoodWard

Project Manager

Tom is easy to please: he is happiest adventuring around by foot or bicycle whenever and wherever he can. Bonus points awarded when accompanied by sun, trees or at least one dog.

Amy Hewett

Executive Support Manager

If you’re looking for Amy, chances are she’s somewhere outdoors – wind in her hair, salt on her skin, and a big smile on her face. Whether she’s halfway up a mountain, lost in a forest trail, or stretched out on a beach, she’s in her element when surrounded by nature.
She’s got a deep love for good food, great wine, and even better company. Amy’s all about good vibes, great food, and the kind of laughter that makes your cheeks hurt.

John Lloyd

Technical Lead: Energy Services

Caffè della Seggiovia in Sauze d’Oulx. John’s favourite bar in his favourite village, tucked away in the Italian Alps. Where they bring you free home cooked Italian food & snacks while you have a few drinks, invariably under bright blue skies surrounded by the snowy mountains.

Jason Casati

Software Developer

Jason loves when he’s at home fixing broken hardware with endless amount of open browser tabs and a cup of tea/coffee attached to his hand.

Kris Ablett

Head of People & Customer in People & Customer

Kris’ favourite places are the kitchen and the dining table and would gladly spend his life simply moving between the two only venturing outside to light a barbecue.

Sal Lehal

FP&A Manager

Sal’s happiest outdoors, exploring with family, fur-babies included. When the kids are elsewhere, you’ll find him somewhere with good food, great company, and an Aperol Spritz in hand.

Andy Sutton

Co Founder & Chief Innovation Officer

Andy likes to be amongst nature or great design (preferable both), whether DIYing, walking, swimming or cycling, though in all instances he’ll want it to be in the sunshine and ending up in a good pub. Or three.

Nathan Chiverton

Senior Software Engineer

Nathan is happiest when spending time with friends, whether that is at the pub, a local gig or a trip away. When he isn’t spending time with friends, he loves listening to music & adding to his ever growing collection of records.

Chris Burton

Lead Software Engineer

Chris is happiest at home, usually deep into a new TV series or tinkering with the latest bit of tech, especially if it makes music. He’s a big fan of good food, cold beer, and catching live music whenever he can.

Liz Cochlin

CTO

Liz is at her happiest when pottering around at home with her husband, son, and pets. She loves the buzz of holidays and music festivals, but nothing beats that first diet coke back on the sofa afterwards. Outside of work, you’ll find her stretching out in a yoga class, getting lost in a good book, or whizzing around Cardiff Bay on roller skates (gracefulness optional).”

Ollie Hanson

Project Co-ordinator

Ollie’s happy place is anywhere he can move, whether that’s hitting the gym, going for a run, or scaling a bouldering wall just for fun. When he needs some downtime, you’ll find him watching films or gaming. When he’s not chasing endorphins or epic storylines, Ollie’s dreaming of adventure in Canada’s wild landscapes.

Hannah Thompson

Customer Experience Specialist

Han’s happiest when she is traveling in Buster, the family camper van. From the breath taking scenic roads of Snowdonia to the gravel tracks of forgotten beaches and undiscovered picnic spots. Getting lost is always bonus adventure!

Craig Walters

Customer Experience Manager

Craig’s happiest when life’s simple, spending time with his wife, children, and Cavapoo Frank. Whether it’s cheering on his kids’ latest interests or planning the next family outing, Craig’s all about making memories together.

Tania LaGambina

Senior Data Scientist

Tania’s happiest when she’s travelling, trying incredible food, and snapping far too many photos along the way. Her favourite place of all? Tokyo, especially on a peaceful early morning, wandering the suburbs on a Conbini coffee run.

Julien Caudron

Julien’s favourite place is the Belgian rural countryside. His parents inherited an old family building, and he spent a big part of his childhood holidays renovating the house, taking care of the garden and enjoying walks in the surroundings.

Josh Skyrme

Systems Engineer

Josh loves spending time with his partner and daughter whether that be chilling at home or adventures out in the sun.

Emma Williams

CCO

Emma’s happiest with a good book, a chilled glass of Sauvignon, and an M&S Jaffa Cake (or two). A proud Welsh speaker, mum of two, and Schnauzer dog-mum, she spends most of her time juggling family life and taxi duties. When Emma gets the chance to slow down, you’ll find her in West Wales, where the pace is gentler and the Wi-Fi just patchy enough for some peace and quiet.

Ellie Karamouzis-Jones

Project Co-ordinator

Ellie is a complete Disney fanatic which has only become more of an obsession since having her little girl. She enjoys cooking and hiking around Wales with her lovely walking group, Walking Wanderers. Ellie is most happiest cosied on the sofa with her family, a hot chocolate and good film!

Matt Elliott

Retrofit Co-ordinator

Rafia Nadeem

Andrew Wong

Senior Software Engineer

Andrew enjoys spending quality time with his family, engaging in the sport of basketball, and pursuing his intellectual curiosity by delving into the fields of technology and science.

Julie Andrews

Customer Care Advisor

An adventurer at heart, Julie is happiest while on holiday with her friends, be it at a nerdy convention somewhere in the UK or a new place around the world she has never visited before. Throw in some tasty food places and perhaps a rum or two and it’s smooth sailing from there!

Matt Burton

CFO

Matt loves a BBQ, especially on a warm sunny day with a cold beer. Walking his two dogs or watching his sons play rugby is often where you will find him on the weekends. Matt’s other passion is of course Disney & Lego.

Natalie Jopling

Retrofit Co-ordinator

Natalie loves visiting beautiful locations around the world (her favorite so far being Bali), learning about the variety of different cultures, whilst watching the sunset on a beach with a cocktail in hand.

Keiron Lloyd

Senior Operations Manager

Keiron is happiest whilst in the Sea, be that dipping his toe during a beach walk with his partner or whilst Scuba Diving in the warmer months (which is ironic given his allergy to Fish).

Dan Murray

System Engineer

Dans favourite place is anywhere with his partner, whether that’s chilling watching Netflix or out having adventures and travelling together.

Kane Dunning

Project Manager

Kane’s happy place is anywhere his family and friends are, especially if there’s food, laughter, and someone else doing the dishes. But his happiest place? That’s the golf course, where the perfect shot is just one swing away. When he’s off the fairway, Kane’s all about making legendary memories with his wife, son, and daughter.

Lee Fisher

Technical Manager

Lee is happiest when relaxing at home with his son and Border Terrier dog. In his spare time Lee is a keen musician and loves all live music. Whether it’s a busker, open mic night or following his ageing 00’s Indie heroes….. If there’s a guitar, and a pint, he’ll be there.

Annie Craze

Project Manager

You can usually find Annie enjoying live music in one of Bristol’s many venues, deep in a book, or climbing hills with her two small dogs and her partner who get dragged along for the ride!

Alex Weaterton

Financial Controller

James Williams

Co-founder and Chief Executive Officer

James is happiest when exploring the Welsh forestry, pure escapism, get as far away from civilisation as possible and be surrounded by the amazing natural environment we have. Usually accompanied by small people carrying sticks.

Jim McArdell

Head of Projects

Jim loves to be in, next to or just generally within sight of the sea be that surfing the waves, walking on the beach or spending time with the family.

Antonia Cosgrove

Senior Customer Care Advisor

Often one to take the road less travelled, Toni is a curious adventurer in love with exploring new places and discovering hidden gems. Be it a city stroll down a quirky lane, or finding herself getting lost in a book.

Melissa Jones

HR Manager

Melissa’s happiest after a busy day, curled up on the sofa with a good TV series and her husband or having  a quiet drink at the local pub. When she’s not chasing after her daughter, she’s discovering a new love for kettlebells at the gym, and loving the challenge!

Hannah Rowland-Jones

Project Manager

Hannah is happiest with saltwater skin and sun on her shoulders. A lover of travel, good food and scuba diving. These days, she finds balance between adventure and home – soaking up newlywed life with her husband and their two cats – her little crew of comfort and chaos.

Abbie Morgan

Billing Operations Lead

Abbie can be found most weekends dancing to a band in one of our local music venues or in a festival field with all her friends doing the same thing. Add in a pint of Guinness and it would be perfection.

Anne-Marie Ratcliffe

Key Account Manager

Anne-Marie’s favourite place is the Arctic. With each dropping degree in temperature, she gets a degree more alive (though this has only been tested to about 20 so there are probably limits…)

Rabz Jabbar

Commercial Development Co-ordinator

Rabz is found happiest when she’s at her favorite place – the Cotswolds (Bourton-on-the-Water), soaking up the landscape and charming views of the stone village. Rabz will often go there in attempt to paint the scenery – albeit failing quite badly, her defense – art is subjective!
