Short answer
Severn Trent supplies Nailsworth with hard water, at about 283 mg/l. That is more than twice the figure for Stroud town centre. Nearly half the homes here date from before 1965. On steep plots, drains, soil pipes and outside taps need extra thought.

How hard is Nailsworth water?
Hard. Nailsworth is in the Severn Trent supply zone ZGL07, which Severn Trent calls Stroud South. The checker gives 19.8 degrees Clark, about 283 mg/l of calcium carbonate.
The supply mixes surface water and groundwater, treated at works in Gloucestershire. Stroud town centre, a few miles north, gets much softer water.
This matters if you move between the two. A kettle or a boiler that was fine in Stroud will scale up much faster here.
What does hard water mean for a new boiler here?
At about 283 mg/l, Nailsworth is above the 200 mg/l line in Approved Document L. The plumber should treat the feed water to the hot water side of a combi boiler, or to a water heater.
In a vented system with a cylinder, scale forms on the coil and the immersion heater. Ask how the plumber will protect both.
A water softener protects the whole house. Give Severn Trent notice before you fit one.
Do Nailsworth cottages have lead pipes?
Some may. In the Nailsworth area, 29.5 per cent of homes on the Council Tax list date from before 1919. Almost half, 46.8 per cent, date from before 1965.
Severn Trent took 7 lead samples in zone ZGL07 in the year to August 2026. The highest was 1.2 micrograms a litre, against a limit of 10. Your own pipes are a separate matter.
On a hillside, the supply pipe can run a long way from the road. The owner is responsible for it from the outside stop valve to the house.
Do the conservation areas affect outside pipework?
Yes. Nailsworth has its own conservation area, and Dunkirk Mills and Watledge is a separate one. In both, a new soil and vent pipe on a wall that faces a road needs planning permission.
The town centre is just outside the Cotswolds National Landscape, but higher ground near it may be inside. Check the map for your address.
Questions
Is Nailsworth water the same as Stroud water?
No. Severn Trent puts Nailsworth in zone ZGL07, at 19.8 degrees Clark. Stroud town centre is in zone ZGL21, at 8.6 degrees Clark.
Do I need to tell Severn Trent about an outside tap?
A tap alone does not appear on the regulation 5 list. A garden watering system that is not worked by hand does, so give notice for that.
Which villages do Nailsworth plumbers cover?
Many also work in Horsley, Woodchester, Amberley and Minchinhampton. Check each firm in the listings for its stated area.
