Do London have water filters for drinking water for free at public place

Yes — London does offer free drinking water in many public places. Here are some of the main ways & where to find them:

What exists

1. Public drinking fountains
   The Mayor of London, together with Thames Water, has installed more than 100 drinking water fountains in busy, accessible public spaces. London City Hall+2London City Hall+2
   These are meant for filling bottles and direct drinking. The Guardian+2London City Hall+2

2. Transport network fountains
   On London Overground, there are several free drinking fountains at stations (e.g. Bethnal Green, Chingford, etc.), and more are being added. Transport for London+1

3. Refill London scheme
   Many businesses like cafes, pubs/restaurants are part of the “Refill London” scheme. They allow you to refill your bottle or get free tap water. You can use an app or look for a sticker in windows. Government Business+2lewishamlocal.com+2

4. Filtered water dispensers
   A few places go beyond just fountains: for example, Hammersmith Bus Station has a refilling station that gives chilled, filtered mains water. Hydrachill
   There are also “Virgin Pure Water Stations” (e.g. in Westfield London) which offer free triple-filtered chilled water. westfield.com

What to note / limitations

• The water from fountains/refill stations is generally tap water, which in London is safe to drink. It may not be “filtered” in the sense of advanced purification (depending on the installation). Most fountains are standard public drinking fountains.

• Filtered or chilled fountains are less common. The case at Hammersmith is more of an exception. Hydrachill

• Sometimes fountains might be out of service, especially in winter or for maintenance.
