"We don't just offer jobs; we offer careers," says The Energy Saving Trust. "Addressing the climate emergency makes working for us meaningful and rewarding."

And it's not just vocation attracting staff to the Trust – an organisation that's seen its headcount increase by more than 120% to almost 450 since 2020 – it's the engaging and supportive culture.

The London-based organisation empowers millions of householders every year to make better energy choices, works with governments to deliver energy programmes and supports businesses to become more energy efficient.

So, it's no surprise that it offers incentives to its staff to do their bit. They can choose where they work, reducing their carbon footprint. There's also the option of an interest-free loan of up to £10,000 to put towards something that saves energy or reduces emissions.

Employees can lease an electric car through a salary sacrifice scheme or take advantage of a cycle hire scheme, so they don't have to buy a bike and equipment themselves.

And it supports the wellbeing of its team, with a £300 yearly allowance – £25 a month – to put towards something that will benefit their mental or physical health, from gym membership to meditation apps.

And the 'star of the month' award encourages the 'feel good' in work as well as out. Every month, staff are given 10 stars to award colleagues demonstrating the values. The person with the most stars gets a £25 prize.
