The NHS advises sterilising all feeding equipment until your baby is 12 months old. The method matters less than the habit — pick the one that fits your kitchen and stick to it.
The three methods
- Electric steam — fastest for daily use; kit stays sterile in the closed unit for up to 24 hours.
- Cold water (Milton) — no power needed, kills bacteria in 15 minutes, kit can stay in solution all day. Unbeatable for travel, camping and grandparents' houses.
- Microwave bags — cheap and quick if you have microwave space.
On prep machines: the NHS method for formula is water at 70°C+ to kill any bacteria in the powder. Prep machines dispense a hot shot then cold water — millions of parents use them; follow the manufacturer's cleaning schedule rigorously and descale on time, because shortcuts are where the risk hides.
Our picks, in detail
Best electric
1.Philips Avent Premium Steam Steriliser with Dryer (SCF293/01)

How we chose
We build every shortlist the same way: we map the whole UK market for the category, weight the specifications that change daily life (not the ones that look good in adverts), cross-reference sustained buyer feedback across multiple retailers, and sanity-check prices across the retailers we link. Retailers cannot pay to appear, and commission never affects rankings. Prices were verified on the "last reviewed" date and will drift — always confirm on the retailer page.
Your questions, answered
How long do I need to sterilise baby bottles?
The NHS recommends sterilising all feeding equipment until your baby is at least 12 months old, alongside washing in hot soapy water (or a dishwasher) first — sterilising is not a substitute for cleaning.
Are formula prep machines safe?
Used exactly as instructed — with regular cleaning, descaling and fresh filters — prep machines dispense a 70°C+ hot shot that meets the NHS temperature guideline for killing bacteria in formula powder. The risk comes from skipped maintenance, not the concept.
Is cold water sterilising as good as steam?
Yes — Milton solution kills bacteria within 15 minutes and items can remain in the solution for 24 hours. It is the method NHS maternity wards have used for decades and needs no electricity.
