Sonos sells the Era 100 in the UK for £199 in black or white, both colours in stock on 20 October 2026, with free delivery and a 30-day return. The cabinet measures 182.5 x 120 x 130.5 mm, and inside it three Class-D amplifiers drive two angled tweeters and one midwoofer. The US price is $219, and the UK shop sets its own price for the same speaker.
Setup is where the cost hides. The Era 100 has to join the Sonos app and a Wi-Fi network before Bluetooth does anything, and a new system starts with an account. Wired input and Ethernet each need an adapter, and an S1-era speaker cannot join the same group. One fixed room, with a second speaker as a real possibility, is the case this fits.
Our verdict
Buy the £199 Era 100 for one fixed room that may gain a second speaker. Skip it if Bluetooth from a phone is the only source: setup runs through the app, an account and Wi-Fi first.
- A good fit for
- A kitchen, study or bedroom that stays put, where app control, AirPlay 2 and a later stereo pair or soundbar are the plan.
- We would skip it if
- A room fed only by Bluetooth, an S1-era Sonos system that must keep grouping, or a household that will not keep a Sonos account.
Reasons to consider it
- £199 at Sonos UK in black or white, both in stock, with free delivery and a 30-day return that Sonos pays for.
- A two-year commercial warranty on all Sonos products, wherever bought, separate from the statutory rights a buyer already has.
- Three Class-D amplifiers, two angled tweeters and one midwoofer in a 182.5 x 120 x 130.5 mm cabinet; two units can be bonded as a stereo pair.
- Wi-Fi 6, Bluetooth 5.3 and AirPlay 2, with a 100-240 V supply and a 6 ft power cable in the box.
The compromises
- No sound until the Sonos app, an account and Wi-Fi are in place; Bluetooth comes after that setup, not before it.
- Wired input and Ethernet each need a separate Sonos adapter, and both are disabled when the speaker serves as a surround.
- The Era 100 runs only on the current Sonos app and cannot be grouped with S1-era speakers.
- Sonos publishes no amplifier wattage or Bluetooth codec list, and its two documents give 2.02 kg and 2.2 kg for the same speaker.
What we have not verified: There is no published wattage or Bluetooth codec list, so loudness and aptX or LDAC support remain unknown. The weight conflict between the product page and the product guide has no resolution. The £199 price is a one-day snapshot, and a second speaker for stereo doubles the outlay.

Price checked 20 October 2026. Retailer prices can change.What £199 buys in the UK
£199 buys the Era 100 in black or white, both in stock, with free delivery and a 30-day return that Sonos pays for. The US shop asks $219 for the same two colours. The UK shop asks £199 for the same two colours; the two prices are set separately.
The hardware is the same on both sides of the Atlantic: three Class-D amplifiers, two angled tweeters and one midwoofer in a 182.5 x 120 x 130.5 mm cabinet. Sonos publishes no wattage for any of the three amplifiers, so there is no power figure to compare with a desktop speaker. The box holds the speaker, a 6 ft power cable and a quick start guide.
The account and the app come first
A new Sonos system starts with an account, verified by email, and an iOS or Android device is required to set up a new system or add a product. The Era 100 must be on Wi-Fi before it can be used as a Bluetooth speaker, which means the app and the network come before the first phone-to-speaker session. A laptop alone cannot complete the setup.
The S1 line is the other boundary. The Era 100 runs on the current Sonos app and is not compatible with the S1 Controller, so an older Sonos household ends up with two apps and two groups that cannot play the same audio together. That is a replacement decision, not an addition.
Two years of warranty, thirty days to change your mind
Sonos's UK terms give a two-year commercial warranty on all its products, wherever the product was bought, and say it sits on top of the rights a buyer already has in law. The product page adds a 30-day return: Sonos refunds the purchase price and covers the shipping back, provided the speaker came from Sonos directly and is returned in its packaging.
That is a more generous paper trail than the US one-year warranty, and it is the main reason the UK price is easier to justify than a straight currency conversion suggests. Keep the order email; the return and the warranty both start from the purchase date.
The wired plan needs an adapter
The Era 100 has one USB-C port and no analogue jack. A turntable or CD player needs a Sonos Line-In Adapter, or the Combo Adapter that adds Ethernet as well. A turntable without a built-in phono stage needs a preamp in the chain, which is a second purchase the speaker does not solve.
Line-in and Bluetooth are both disabled when the Era 100 is used as a surround speaker, so the wired plan only works in a room where the speaker plays music on its own. The adapter is small, but it is a separate purchase for anyone with a deck.
When the £199 is the wrong speaker
Skip it if the room will only ever be fed by Bluetooth from a phone. The Era 100 must be set up on Wi-Fi through the app first, so a Bluetooth-only plan buys an account, an app and a network setup for a job a portable does without them. Rule it out as well if an S1-era system has to keep playing in the same group, or if nobody wants to maintain a Sonos account.
A fixed speaker with a streaming app, a turntable or an occasional AirPlay session is the job the £199 covers. A second Era 100 for stereo is another £199, so the pair comes to £398; buy the first one only if that second purchase is plausible.
