In the UK, an average household throws away 40kg of recyclable plastic every year, including 150 water bottles. As a country, we get through over half a billion plastic water bottles every month. Much of this waste ends up polluting the oceans, with experts predicting there will be more plastic than fish in the sea by 2050. And in case you need any more persuading, there’s also a high eco-cost involved in the processing of bottled water, with a single 1 litre bottle taking 6 litres of water to produce.

All of which makes reusable water bottles a no-brainer.

Whether you fill it up with tap, filtered or even flavoured water, it’s one of the best green investments you can make. It will also save you money in the long (or not so long) term. We each use an average of 3 plastic bottles per week, with bottled water costing 50-80p per 500ml, so the cheapest of the bottles listed below will have paid for itself in around 6 weeks.
