When it comes to keeping your office hydrated, choosing the right type of water cooler can have a big impact, not only on your team’s health and wellbeing but also on your budget, sustainability efforts, and day-to-day convenience. The debate between mains-fed (also known as plumbed-in) water coolers and bottled water coolers is ongoing, but for many modern businesses, mains-fed options are emerging as the clear winner.

Cost-Effective and Budget Friendly
One of the most compelling reasons to choose a mains-fed cooler is cost-efficiency. Bottled coolers require regular delivery of large plastic bottles, which can be expensive over time, especially in busy offices. Mains-fed units are connected directly to your building’s water supply, meaning unlimited water at a fixed monthly cost.
If you already have a bottled cooler, businesses can save hundreds, if not thousands of pounds a year by switching to a mains-fed water cooler, especially in high-usage environments.
Better for the Environment
If your company is serious about sustainability, then a mains-fed cooler is the eco-friendly option.
A bottled water cooler delivery typically involves 19 litres plastic bottles, which must be stored, handled, and eventually disposed of or recycled. A mains-fed system removes the need for plastics bottles entirely.
Bottled water has to be transported, sometimes long distances, using fuel and contributing to emissions. Mains-fed systems eliminate these journeys, significantly reducing the carbon footprint.
No Lifting or Storing
Bottled water coolers aren’t just inconvenient they can be a manual handling hazard. 19-litre bottles can weigh 20kg when full. Regularly lifting and replacing them poses a real health and safety risk, especially for office staff.
Mains-fed coolers take up less space because there’s no need to stockpile spare and empty bottles. That means a cleaner, tidier environment with less risk of hazards.
Constant Supply of Filtered, Great-Tasting Water
All our mains-fed water coolers come with filters that remove chlorine, odours, sediment, and other impurities. The result? Clean, crisp, great-tasting chilled water straight from your tap.
Whether your team is working through a heatwave or staying hydrated on busy office days, you’ll never run out of water or have to wait for the next delivery.
Final Thoughts: Time to Make the Switch?
Choosing the right water cooler is about more than just hydration it’s about cost savings, environmental responsibility, convenience, and employee wellbeing.
