Our Block Salt For Water Softeners Products
What is Block Salt For Water Softeners?
Block salt for water softeners comes in solid rectangular blocks rather than loose granules or tablets. Each pack contains two 4kg blocks (8kg total) designed to slot directly into the salt cabinet of your water softener. As your softener operates, the blocks dissolve gradually, regenerating the resin beads that strip hardness minerals — calcium and magnesium — from your water supply.
Block salt is used exclusively in block-fed water softener systems such as Harvey Crown, Harvey TwinTec, Harvey miniMAX, and all Kinetico block-fed models. If you’re unsure whether your softener takes block salt or tablet salt, check your softener’s manual or give us a call on 01276 28815 — we’re happy to advise.
Harvey Block Salt vs Kinetico Block Salt — What’s the Difference?
Both Harvey block salt and Kinetico block salt are 2x4kg packs of 99.9% pure salt and perform identically in terms of water softening. The difference is purely branding — Harvey block salt is the recommended salt for Harvey water softener systems, while Kinetico block salt is the recommended salt for Kinetico systems. In practice, block salt from either brand will work in any block-fed water softener, but we stock both so you can order the brand your system recommends.
Block Salt For Water Softeners Prices & Multi-Buy Discounts
We offer competitive block salt prices with discounts for larger orders — the more you order, the lower the price per pack. This makes it well worth stocking up, especially as block salt stores easily and has an indefinite shelf life.
Harvey block salt starts from £5.50 per pack on multi-buy orders. Kinetico block salt starts from £6.25 per pack. See each product page for the full pricing breakdown.
Buying in bulk is the easiest way to get the cheapest block salt prices while ensuring you never run out. Many of our customers order 10–20 packs at a time and store them in their garage or utility room.
Why Surrey Homes Need Block Salt For Water Softeners
Surrey has some of the hardest water in England — the chalk and limestone geology of the North Downs means water picks up high levels of calcium and magnesium before it reaches your tap. Hard water causes limescale buildup in kettles, boilers, washing machines and pipes, reducing appliance efficiency and lifespan.
A block salt water softener removes these minerals continuously, protecting your home. But it only works if it’s kept topped up with the right salt — which is where regular block salt delivery makes life easy.

Frequently Asked Questions
How often do I need to replace block salt? Most households replace their block salt every 2–4 weeks. Surrey’s very hard water means your softener works harder, so you may find you’re closer to every 2 weeks. Checking monthly is a good habit to avoid running dry.
Can I use block salt in any water softener? No — block salt is only compatible with block-fed water softener systems such as Harvey and Kinetico models. If your softener uses a brine tank it will need tablet salt or granular salt instead. Not sure which yours uses? Call us and we’ll help.
What’s the difference between block salt and tablet salt? Block salt comes in solid 4kg blocks and is loaded directly into the salt cabinet of block-fed softeners. Tablet salt is smaller compressed pellets used in metered or timer-based softeners with a brine tank.
Is block salt the cheapest way to soften water? Block salt is very cost-effective, especially when bought in bulk. Our multi-buy prices make it significantly cheaper per pack than buying individually from retailers, and free local delivery means no extra costs on top.
Do you deliver block salt near me? If you’re within 15 miles of Camberley we deliver for free. Use our postcode checker to confirm, or call 01276 28815.
Can I buy Harvey block salt cheaper than from Harvey directly? Yes — as an independent local supplier we’re not tied to manufacturer retail pricing. Our Harvey block salt starts from £5.50 per pack on multi-buy orders, which is typically cheaper than buying direct or from general retailers.
