Best Glass Baby Bottles UK: 5 Options Compared

If you have searched for “Avent glass bottles” you already have the instinct that matters: the bottle material is worth thinking about. The research backs it up. Standard polypropylene bottles shed microplastics into warm formula in large numbers, and a glass body is the simplest way to remove that source.

This guide compares the glass baby bottles you can actually buy in the UK right now — Philips Avent, MAM, NUK, Hevea and Tommee Tippee — on the things that decide a purchase: size, teat material, sterilising, and the honest downsides of weight and breakage. For the underlying science, see our companion guide to microplastics in baby bottles.

Why Glass, Briefly

The 2020 Trinity College Dublin study in Nature Food tested ten polypropylene bottles that between them account for 68.8% of the global market. It found they release microplastics at values as high as 16.2 million particles per litre, and that sterilisation and high-temperature water significantly increase the release. Heat was the driver — the hotter the liquid, the more the plastic shed.

Glass sidesteps this entirely. Borosilicate and temperature-resistant glass are inert: they do not shed microplastics no matter how many times you sterilise or reheat. That is the whole case for glass, and it is a strong one. What glass does not fix is the teat (almost always silicone, occasionally natural rubber) and, on most bottles, a polypropylene collar or cap — but those are minor next to a whole heated bottle.

The UK Options Compared

Every bottle below is currently sold through UK retailers. Sizes, teat materials and specifications are taken from each manufacturer’s own listings.

Bottle	Glass type	Sizes (UK)	Teat	Sleeve	Notable
Philips Avent Natural Response Glass	Borosilicate	120ml, 240ml	Silicone, breast-shaped	Not included	Widest retail availability; anti-colic valve
MAM Feel Good Glass	Temperature-resistant	90ml, 170ml, 260ml	Silicone (SkinSoft)	Not included	Slim, minimalist shape
NUK First Choice+ Glass	Borosilicate	120ml, 240ml	Silicone or latex	Not included	Orthodontic teat; see recall note below
Hevea Glass	Borosilicate	150ml, 250ml	Natural rubber, one-piece	Natural rubber, included	Closest to fully plastic-free
Tommee Tippee Natural Start Glass	Borosilicate	150ml, 250ml	Silicone, breast-like	Not included	Self-sterilising design; anti-colic valve

A note on the two glass types: borosilicate (Avent, NUK, Hevea, Tommee Tippee) has very low thermal expansion, so it copes well with the heat cycling of sterilising and warming. MAM describes the Feel Good as temperature-resistant glass rather than borosilicate; it is still made to be sterilised and microwaved, but as a general rule borosilicate tolerates sudden temperature changes best. Whichever you choose, avoid extreme shocks — do not pour boiling water into a fridge-cold bottle.

Bottle by Bottle

Philips Avent Natural Response Glass — the mainstream default

The bottle most “Avent glass” searchers are already half-decided on. The Natural Response glass bottle uses borosilicate glass that is heat and thermal-shock resistant, with a wide, breast-shaped silicone teat and an anti-colic valve that releases milk only when the baby actively drinks. It comes in 120ml and 240ml and is stocked more widely than any other glass bottle in the UK, which matters when you need a replacement at short notice.

Pros: easiest to buy and to find spares for; well-regarded teat; genuine borosilicate. Cons: no sleeve in the box (buy separately); only two sizes.

MAM Feel Good Glass — the design-led pick

MAM’s Feel Good glass bottle pairs temperature-resistant glass with the brand’s SkinSoft silicone teat, in a slim, understated shape that many parents prefer to hold. It comes in three sizes — 90ml, 170ml and 260ml — the widest range here, which suits the tiny newborn feeds where the 90ml earns its place. It can be microwaved, dishwashed and sterilised at high temperature.

Pros: three sizes including a genuine newborn 90ml; widely accepted teat; clean design. Cons: temperature-resistant rather than borosilicate glass; no sleeve included.

NUK First Choice+ Glass — the orthodontic teat

NUK’s glass First Choice+ uses borosilicate glass with the brand’s orthodontic teat — a flatter shape intended to sit comfortably against the palate — available in silicone or latex, plus an anti-colic air system. Sizes are 120ml and 240ml.

One honest caveat: in 2022 the US Consumer Product Safety Commission recalled certain decorated NUK First Choice glass bottles sold on Amazon.com over lead in the exterior decorative paint (not the glass or the milk-contact surfaces). It was a US decoration issue, but if you like NUK, a plain undecorated glass bottle avoids the concern entirely.

Pros: distinctive orthodontic teat; latex option for parents who prefer it. Cons: the 2022 US decoration recall; two sizes only.

Hevea Glass — the closest to fully plastic-free

If your goal is to eliminate synthetic polymers as far as possible, Hevea is the answer. The bottle is 100% borosilicate glass, the teat is a one-piece natural rubber design (cherry-shaped, with the anti-colic valve built into the teat itself), and even the protective sleeve is natural rubber. No silicone, no polypropylene, nothing plastic touches the milk. The wide neck makes scooping formula easy, and it can be boiled, steam-sterilised and dishwashed. Sizes are 150ml and 250ml. UK stockists include Babipur.

Pros: genuinely plastic-free milk path; natural rubber teat and sleeve; one-piece teat is quick to clean. Cons: natural rubber teats wear faster than silicone and are unsuitable if there is a latex allergy in the family; priciest option.

Tommee Tippee Natural Start Glass — the anti-colic all-rounder

Tommee Tippee’s glass line (formerly Closer to Nature, now Natural Start) uses borosilicate glass with a breast-like silicone teat, an anti-colic valve in the teat, and a self-sterilising design, in 150ml and 250ml. It is stocked in supermarkets including Tesco, which makes it easy to top up. Note this is a different product from the plastic Closer to Nature bottle — only the glass line removes the polypropylene body.

Pros: supermarket availability; well-liked anti-colic teat; scratch and stain resistant. Cons: two sizes; sleeve not included.

Who Glass Is — and Isn’t — For

Glass is a strong fit if:

• You are formula feeding, where the bottle is heated and sterilised repeatedly — exactly the conditions the Nature Food study measured.
• Your baby is a newborn or young infant, when they cannot yet hold or hurl the bottle and exposure per kilogram of body weight is highest.
• You want the simplest, most certain way to remove the microplastic-shedding bottle from feeds.

Glass is a harder sell if:

• You have hard floors and butterfingers at 3am — a dropped glass bottle can shatter. A sleeve helps a great deal, but does not make it unbreakable.
• Your baby is self-feeding and throwing bottles, in which case stainless steel is more practical (and still microplastic-free).
• You need the very lightest bottle for travel, where weight adds up across a changing bag.

The weight-and-breakage objection is real and we will not pretend otherwise. But the two mitigations are straightforward: use a sleeve (included with Hevea, sold separately for the rest), and lean on glass hardest in the newborn months, transitioning to stainless steel sippy cups as your baby becomes more mobile. For the wider weaning stage, see our microplastic-free weaning products guide.

The Verdict

• Easiest to buy and live with: Philips Avent Natural Response Glass — everywhere, with spares always in stock.
• Best size range: MAM Feel Good Glass, with a true 90ml for newborn feeds.
• Sleeve included, closest to fully plastic-free: Hevea, with a natural rubber teat and sleeve and nothing plastic touching the milk.

Any of them removes the polypropylene bottle that the research is actually concerned about. Beyond the bottle, the single most effective habit is preparing formula the way the Trinity researchers themselves recommend — mixing it in a non-plastic container and cooling before it touches any plastic. Our baby bottles guide and baby food and formula guide explain that method in full, and our baby items category collects our other verified picks.
