Meet the father and daughter in power for 64 years – keeping London’s lights on
A father and daughter duo have been helping to keep London’s lights on for a combined 64 years - crediting their long service to the “loyalty and pride” they both feel for UK Power Networks.
Sarah Day, customer services manager for central London, started her career in power 17 years ago after walking into the Falconwood office as an engineering assistant at 20 years old.
She’s since progressed through the company and now leads a team of ten people as customer services manager in the Covent Garden office, looking after some of the most important stakeholders in the capital and country.
But she was no stranger to the world of power as she was following in her dad Terry’s footsteps into the industry.
London Power Network legend, Terry Day has clocked up 47 years at UK Power Networks and predecessor companies, including the London Electricity Board, where he started as storekeeper at the Sydenham depot in 1978 at the age of 22.
Now working as field staff supervisor in the Brixton office, his years of experience and expertise are guiding the new generation of power workers that keep the city’s lights on safely and reliably.
Over the years, he moved through a variety of roles and locations, first to Bexleyheath as a supervisor, then in 1988 to Brixton as stores manager, where he looked after all the London stores and Brimsdown plant stores. He also spent time working in Maidstone, Kent and Bury St Edmunds, Suffolk.
After 30 years in logistics, Terry decided it was time for a new challenge and took up a position as performance team leader and field staff supervisor, returning to Brixton where he’s been ever since. Looking back on 47 years at UK Power Networks, Terry says the reason he’s stayed so long is job fulfilment and the people he’s worked with.
He said: “You are only as good as your team and across my career, I have met some great people that have supported me, some of whom are now directors. For me, UK Power Networks is part of my career, but the last 15 years have been the best part. The rewards are brilliant, and it may sound corny but I’m sure Basil, the CEO, sees us all as one big family.”
Terry encouraged his daughter Sarah to join UK Power Networks, knowing it’s a great place to work. He’s proud of her progress from engineering assistant to customer services manager, and says, “I was so proud when she got the job and even prouder now, she is a manager. It makes me proud when I hear all staff from field staff to senior managers and directors speak highly of her.”
Their paths cross quite often at work, and Terry admits, “If it’s serious, it’s ‘Hi Terry’ or ‘Hi Sarah’. If it’s not serious, it’s ‘Hi Dad/Sarah’. We work for the same department, so we cross paths quite a lot.”
Working at the same company has become a bit of a family joke. “We can be a bit boring at the dinner table because we always drift into discussions about what’s going on at work,” he says.
After leaving sixth form, Sarah knew she wanted to work in an office. Her dad Terry, who was already at UK Power Networks, told her about an office administrator job in East London. She worked there for two years until he mentioned an opening at Falconwood as an engineering assistant. “I never thought that I would end up working at the same company as my dad. I just knew that I wanted to go to work and earn money,” she said.
On her first day at Falconwood, Sarah said “I was so nervous, but I was very lucky as the engineering assistant role was a new role at that office and I was able to make it my own.
“I can’t say that I got any special treatment and I didn’t expect to, I wanted to make a good impression and prove I got the job on my own merit. Nine months in, I helped coordinate the response to a huge high-voltage fault, and I really enjoyed that as I got to meet lots of people in the business and see how everyone worked together.”
In 2014, Sarah moved to the Covent Garden office in central London to help set up a new department focused on customer service in the area. “As it was a new office, there wasn’t anyone for me to take over from so again I was able to make the job my own.” She trained new team members and, in 2018, became customer services manager, a role made permanent in 2019. “We have made some positive changes in Central London, and I absolutely love my job and my team.” She added.
Seventeen years on, Sarah’s biggest motivators have been the impact of the projects and the people she works with. “Knowing the difference that this makes to our staff and our customers gives me a great sense of pride.”
Her professional development has gone from strength to strength, completing her City and Guilds and Chartered Management Institute Level 5, through the company’s Supported Studies programme and internal Leadership Academy, saying “I have gained a great sense of confidence in the role I do now my job lets me empathise with customers and provide that support and empathy in their time of need and I’ve made friends for life.”
“Dad and I often cross paths at work. He will phone me when he needs a favour and likewise. We both manage teams of people. Me, office staff and him, field staff so we do cross paths all the time, which is actually really nice.”
“Working at the same company is great, lots of people that I meet know my dad or some people that meet him say… oh I know your daughter. We don’t really make jokes about it, but we always ‘talk shop’ when I go to his house even though we don’t mean to.”
Sarah added: “Together, our combined 64 years reflects not only a family legacy but also the commitment, loyalty and pride we both feel in being part of this organisation.”
UK Power Networks has over 350 members of staff who have completed more than 40 years of service – dubbed the 40+ Club, which includes Terry.
