Milton tablets or an electric steam steriliser for a small kitchen?

What does NHS actually list — tablets or a steam unit?

The NHS sterilising pages name methods, not shop SKUs: boiling, steam sterilising (electric or microwave), and cold-water sterilising solution. Milton tablets (or fluid) are a branded way to make that cold-water solution. An electric steam steriliser is one way to do the steam method. Both sit on the NHS list. Neither is written as the one you must buy.

NCT describes cold-water products as tablets, concentrated liquid, or a ready-made solution, and steam as a microwave box or a mains unit. For a small kitchen the useful split is footprint and power, not a ranking of brands.

How do I use Milton-type tablets the NHS way?

Wash and rinse first — the same as for boiling or steam. Best Start in Life then gives the cold-water steps.

  1. Make up the solution from the pack Follow the tablet or fluid label for how much water. Milton’s own UK page currently says 1 tablet in 5 litres of cold water. That dilution is the maker’s instruction, not an NHS recipe.
  2. Submerge with no air bubbles NHS: make sure no air is trapped in bottles or teats. Keep everything under the solution with the floating cover, plunger or submerger.
  3. Leave at least 30 minutes NHS: leave feeding equipment in the solution for at least 30 minutes. Milton’s current product copy says 15 minutes for its own solution. The NHS floor on the national pages is 30 minutes.
  4. Change the solution every 24 hours NHS and Milton both say to renew the solution every 24 hours. Items can stay in the solution until you need them.
  5. Rinse with cooled boiled water When you make up a feed, NHS says: if you used a cold-water steriliser, shake off excess solution or rinse the bottle and teat with cooled boiled water from the kettle (not tap water).

This page does not treat a shop price for a tub of tablets as a fact. Running cost is ‘tablets or fluid plus cold water’, which you can compare with a unit’s electricity and the worktop it occupies.

Which takes less worktop in a small kitchen?

Hob alternativeNot neededNot needed — boiling in a pan is the third NHS method if you want neither
NHS timings checked 10 September 2026 on the sterilising baby bottles page, Best Start in Life sterilising page, and making-up-formula rinse line. No tablet or unit prices — those change by shop and are not official rates.

A microwave steam box is also on the NHS steam line and may stack away after use, but it needs an empty microwave and the maker’s water measure. It is not a tablet method and not a UV box.

When do tablets fit a small kitchen better than a steam unit?

  • Cupboard space, no spare socket. A watertight box with a cover that holds bottles under the water matches the NHS floating-cover rule and does not need to stay plugged in.
  • Night feeds. You can lift one bottle from the solution, rinse with cooled boiled water, and leave the rest soaking. Steam units are a batch: run a cycle, then follow the maker on how long the closed lid ‘counts’.
  • Travel or a second room. Tablets and a lidded container move; a mains steam unit does not.
  • You already boil on the hob. You do not have to add either product. Boiling is already an NHS method.

Pick steam instead if you want a dry cycle with no chemical solution and you have a permanent square of worktop. Follow that unit’s instructions — NHS does not publish one steam runtime for every model.

In shortIn short: for a small kitchen, NHS cold-water tablets are the worktop-light option — 30 minutes submerged, new solution every 24 hours, rinse with cooled boiled water. An electric steam unit is the other listed method if you have the socket and the square. Neither is a required buy if you are willing to boil.

Questions parents ask

Is a Milton tablet the same as the NHS cold-water method?
It is one branded way to make the NHS cold-water sterilising solution. NHS timing is at least 30 minutes under the solution, no trapped air, a floating cover, and a fresh solution every 24 hours. Milton’s own UK instructions currently say 15 minutes for its solution — follow the pack for dilution, and use the NHS 30-minute floor on the national pages.
Do I have to buy Milton’s branded tub?
NHS asks for a floating cover or plunger so everything stays under the solution. That can be the branded box or another clean, watertight container with a cover that holds bottles down. The method is the solution and the submersion, not the logo on the lid.
Do I rinse with tap water after tablets?
NHS making-up-formula steps say to shake off excess solution or rinse with cooled boiled water from the kettle, not tap water. NCT also says to rinse with cool boiled water after cold-water sterilising.
Which is cheaper, tablets or an electric unit?
This page does not publish a tablet price or a unit price as a fact — those figures move by retailer. Compare ‘tablets or fluid plus water, no socket’ with ‘upfront unit plus electricity plus a permanent worktop square’, then check today’s shelf price yourself.
