Moderately hard
Severn Trent Water
Water in Nottingham
- Nottingham is supplied by Severn Trent and sits towards the harder end of that company's very wide range, generally in moderately hard to hard territory.
- Much of the local supply comes from Sherwood Sandstone aquifers, which pick up more mineral content than the upland reservoir sources supplying the western part of Severn Trent's area.
- This puts Nottingham in the band where the softener-versus-inhibitor question is genuinely open, rather than obviously settled either way — which is the most useful thing to know before spending anything.
- Because Severn Trent's area spans soft to very hard, a Nottingham household's water differs materially from a Birmingham household's despite the same supplier and the same region.
- Local installers routinely work across both moderately hard Nottingham and softer parts of Derbyshire, so they tend to be comfortable with both product routes.
Your water is moderately hard — worth protecting the boiler, not much more.
Scale will build up slowly on heated surfaces. A scale inhibitor on the boiler is proportionate and inexpensive, and some manufacturers start asking for one around this level. A softener is still difficult to justify on cost. Test your own tap before deciding — at this level the exact figure matters.
