How much does a Reverse Osmosis system cost?

A fully installed home RO system usually costs between £600 and £1,000 depending on the model and number of filtration stages. It’s a one-off installation with only annual filter changes needed and far more cost-effective than buying bottled water every week.

How long does it take to install?

Most systems are fitted in 1–2 hours. We’ll install everything neatly under your kitchen sink and make sure the new tap looks clean and discreet. No mess.

Will it remove all the bad stuff from my water?

Reverse osmosis removes the vast majority of known contaminants. It’s used in medical, commercial and domestic settings for this exact reason. If you want maximum protection, it’s the gold standard.

Does it remove healthy minerals too?

Yes - the process is so thorough it strips most minerals out. Some people prefer this; others choose a remineralisation filter, which we can supply if you want to add calcium and magnesium back in.

Is it safe to drink every day?

Absolutely. RO water is safe for daily drinking, cooking, and even for your pets. It’s clean, clear and better for your kettle too - no more limescale build-up.

How often do I need to change the filters?

Most systems require annual filter changes, which we can handle for you as part of a regular maintenance check or one-off visit.

What Is a Reverse Osmosis Water Filter?

A high-performance way to purify your drinking water.

Reverse osmosis is a process that uses pressure and a semi-permeable membrane to remove unwanted particles from your water. It’s one of the most effective ways to filter tap water at home - used everywhere from restaurants and hospitals to family kitchens.

A typical system includes multiple filters to remove sediment, chlorine, bacteria, heavy metals, and chemicals, followed by a final membrane stage that removes even microscopic contaminants.

That means it can help get rid of:

Chlorine and chemical residues
Lead, mercury, arsenic and other metals
PFAS (the so-called ‘forever chemicals’)
Pesticides and fertiliser run-off
Microplastics and sediment
Bad odours and unpleasant tastes

You’ll notice the difference instantly - especially when it comes to drinking water, tea and coffee, or cooking.
