Find someone to fit water filtration in County Durham, and find out what is actually worth fitting — County Durham has soft water, and that decides most of it.

Northumbrian Water

Water in County Durham

  • County Durham has soft water supplied by Northumbrian Water from Kielder and other upland reservoirs.
  • Softeners have no real market here and limescale is not a domestic issue.
  • The county's former coalfield housing stock is largely pre-1939, and soft plumbosolvent water in older pipework is a more relevant filtration driver than scale.
  • The North Pennines include properties on private supplies requiring disinfection and sediment treatment.
  • Commercial filtration demand centres on hospitality and food production.

You have soft water — there is no limescale problem to fix.

A water softener would be money spent on a problem you do not have, and anyone trying to sell you one here is worth questioning. If you want to improve your water it will be about taste, chlorine or older pipework, not hardness. Soft water is also slightly more inclined to dissolve metals from old plumbing, which is a different reason to filter drinking water.

What to consider in County Durham

Based on soft water, not on what earns us the most.

Under-sink filters

A filter housing plumbed into the cold supply under your kitchen sink, feeding either your existing tap or a separate filter tap. The most popular way to get filtered drinking water in a UK home.

Carbon filters

Activated carbon cartridges that adsorb chlorine, organic compounds and the things that make water taste and smell wrong. The workhorse of domestic filtration.

Inline filters

A sealed cartridge fitted directly into a water line, most often feeding a fridge, an ice maker, a coffee machine or a drinks dispenser.

Shower filters

A compact filter fitted between the shower arm and the head, aimed at chlorine and its effects on skin and hair.

Frequently asked questions

Is the water hard in County Durham?
County Durham is supplied by Northumbrian Water, and the water is typically soft. That means limescale is not a significant problem, and a water softener would be money spent on something you do not have. Check your own postcode for the exact figure.
How much does water filter installation cost in County Durham?
Indicative UK labour runs from around £120 for a straightforward under-sink filter to £400–£900 for a water softener, with commercial work higher. Local rates vary. We do not set installer prices and take no commission — get three quotes and compare what is included, not just the headline figure.
Do I need a WaterSafe-approved plumber in County Durham?
Not for every job, but it helps. WaterSafe-approved plumbers can self-certify work that would otherwise need notifying to your water company in advance, and the register is a genuine competence check you can search free. For anything cutting into the rising main — a softener or a whole-house filter — we would use one.
