Tommee Tippee Perfect Prep Review Is a £75 Formula Machine Actually Worth It?
A full review of the Tommee Tippee Perfect Prep Day & Night — covering how it works, whether it is safe according to NHS guidance, the ongoing filter cost, and the honest answer on whether it justifies its price for formula-feeding families.
The Tommee Tippee Perfect Prep is the fastest and most convenient way to make a formula bottle in the UK — a 2-minute bottle at the correct temperature, at any hour, without waiting for a kettle to cool. For formula-feeding families in the newborn stage, when every feed matters and every minute of sleep is precious, this convenience is significant. The honest limiting factor is the ongoing filter cost (approximately £60–£80 per year) and the machine’s correct relationship to NHS formula preparation guidelines, which requires understanding. It is not a product for every formula-feeding family, but for those who formula feed exclusively from birth — it earns its place.

② How It Works — The Two-Shot System
The Perfect Prep uses a two-stage process to produce a ready-to-feed bottle at body temperature in approximately 2 minutes. Understanding the system is important for both safe use and for assessing whether it meets NHS preparation standards.
③ Is It NHS-Safe?
This is the question most parents ask and most reviews handle poorly. The answer is: yes, when used correctly — with one important caveat to understand.
The NHS and WHO recommend preparing formula with water at 70°C or above to kill any bacteria present in the formula powder. The Perfect Prep’s hot shot reaches this temperature threshold for the initial powder-dissolving step. Independent testing by Which? and subsequent review by Tommee Tippee confirmed the hot shot temperature is sufficient to kill the relevant bacteria (Cronobacter sakazakii and Salmonella) that can be present in formula powder.
The caveat: safety depends on the user following the correct sequence — adding formula to the hot shot before the cool water top-up, not the other way around. The machine dispenses the hot shot first by design, but the user must add powder at that stage. Parents who add powder after the cool water top-up (bypassing the hot-shot sterilisation step) are not using the machine safely. Tommee Tippee’s instructions are clear on this sequence — but the risk of user error is worth noting.
④ The Ongoing Filter Cost
The Perfect Prep’s activated carbon filter removes chlorine and impurities from the tap water used for the cool-water top-up. Tommee Tippee recommends replacing the filter every 3 months or after 150 uses — whichever comes first. For a family making 7–8 bottles per day in the early weeks, 150 uses is reached in approximately 3 weeks rather than 3 months. The filter cost is therefore significantly higher for exclusively formula-feeding families in the newborn period than the quarterly replacement schedule implies.
At £15–£20 per filter and approximately 17 filters in the first year (based on 7 feeds per day), the annual filter cost is approximately £255–£340 for a family exclusively formula-feeding from birth. This is the most significant hidden cost of the Perfect Prep and the figure most often missing from purchasing decisions. Combined with the machine price of £75, the first-year total is approximately £330–£415.
⑤ Night Feeds — The Real-World Test
The Perfect Prep’s strongest argument is night feeds. A hungry newborn at 3am while sleep-deprived presents a specific challenge: measuring formula powder accurately, using water at the correct temperature from a flask or kettle that must be allowed to cool, and waiting for the bottle to reach the right temperature. The Perfect Prep compresses this into pressing two buttons and waiting 2 minutes, in a dimmed night mode that does not wake your partner.
The day-and-night model reviewed here has a specific night mode — reduced display brightness and quieter pump operation — that makes bedside use genuinely practical. Parents who keep the machine on the bedroom floor or a bedside table report that night feeds with the Perfect Prep are significantly less disruptive than the flask-and-kettle alternative. This is the use case where the £75 purchase price is most clearly justified.
⑥ vs Making Formula Manually
The NHS manual method: boil a full kettle, allow to cool for no more than 30 minutes (to 70°C or above), measure powder, add to water, cool to body temperature under cold running water. Total time from start to feed: approximately 10–15 minutes if a fresh kettle is used, or 2–3 minutes if a pre-cooled flask is prepared in advance.
The flask method (boiling the kettle, filling a vacuum flask with 70°C+ water before bed, using it for night feeds) is the most common manual workaround. It reduces night-feed preparation time to approximately 2–3 minutes and costs nothing beyond the flask. The Perfect Prep’s advantage over the flask method is freshness (flask water should not be stored for more than 2 hours at feed temperature), consistency (no guessing how hot the flask water still is), and the elimination of the cooling step.
For families who are comfortable with the flask method and confident in the temperature management, the Perfect Prep’s convenience advantage narrows significantly. For families who find the flask method anxiety-provoking or error-prone in a sleep-deprived state — the Perfect Prep removes the uncertainty.
Worth buying if you exclusively formula feed and night feeds are a priority. Factor in the filter cost before deciding.
The Perfect Prep earns its 8.7 for delivering exactly what it promises: a correctly-prepared, correctly-temperatured formula bottle in 2 minutes, at any hour, without thermometers or cooling steps. For exclusively formula-feeding families navigating the newborn stage, this convenience is genuinely valuable and the £75 machine cost is easily justified by the quality-of-life improvement to night feeds alone.
The filter cost is the calculation every family needs to do before buying. If you use branded filters at 150-use intervals with 7 feeds per day, the first-year cost is approximately £415 including the machine. Third-party compatible filters reduce this to approximately £175. Factor in your feeding frequency, filter source and comfort with third-party parts before committing.
