Tap water in Edinburgh is supplied by Scottish Water, the publicly owned utility for the whole of Scotland. Edinburgh's water is drawn largely from upland reservoirs — the Glencorse system in the Pentland Hills and the Talla and Megget reservoirs in the Scottish Borders. These are peat and granite catchments rather than chalk or limestone, which is why the water is so soft.
Yes. Edinburgh tap water meets every standard set for drinking water in the UK. Lead, nitrate, bacteria and disinfection by-products are all comfortably within legal limits, and Scottish Water has no active PFAS enforcement notice. Water quality is regulated by the Drinking Water Quality Regulator for Scotland (DWQR). The figures on this page come from Scottish Water's 2025 reporting.
Edinburgh has very soft water. The main Glencorse supply, which covers most of the city, measures around 30 mg/l CaCO₃. Across all of Edinburgh's supply zones the range runs from roughly 15 mg/l (Marchbank) up to about 68 mg/l (Castle Moffat), so every part of the city sits in the soft or very soft band. This figure comes from the Scottish Water Water Hardness Data 2024 dataset.
For context, hardness below 60 mg/l is very soft, 60–120 is soft, 120–180 is slightly hard, 180–250 is moderately hard, 250–310 is hard, and above 310 mg/l is very hard. Much of southern and eastern England exceeds 250 mg/l, so Edinburgh's water is dramatically softer than London's or Cambridge's. In practice that means almost no limescale in your kettle, and no need for a water softener. Compare your own area on the UK hard water map.
No. Scottish Water does not add fluoride to tap water anywhere in Scotland, and Edinburgh is no exception. The only fluoride present is naturally occurring, measured at about 0.12 mg/l across the city's zones. That is far below the 1.5 mg/l legal limit and well under the roughly 1 mg/l target used by the artificial fluoridation schemes that operate in parts of England.
Chlorine in the main Glencorse supply averages around 0.1 mg/l, which is low. A small residual of chlorine is added to keep water safe as it travels through the pipe network — this is standard across the UK. If you notice a faint chlorine taste or smell, leaving an open jug of water in the fridge for an hour lets most of it disperse, as will a simple carbon filter jug.
Water leaving Scottish Water's treatment works contains essentially no lead — average readings across Edinburgh's zones are below 1 µg/l, against a legal limit of 10 µg/l (due to tighten to 5 µg/l in 2036). Where lead does appear in tap water, it comes from old lead pipes and plumbing inside individual properties, not from the public mains. Homes built before 1970 are the most likely to still have some lead pipework. You can check the likelihood for your own address with the lead pipe risk checker, and read more in our guide to lead pipes in UK homes.
For safety, no — Edinburgh tap water is safe to drink straight from the tap. Because the water is so soft, there is also no limescale reason to treat it, so a water softener would be pointless here. Some people still prefer a carbon filter jug purely to soften the taste of chlorine. If you want to remove the widest possible range of trace substances, a reverse osmosis system does that, though it is more than most Edinburgh households need.
