Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
This guide compares stated features rather than the listings' plaque-removal claims. Battery life is stated on three of the six listings (Oral-B iO2, Novalun, OasiSmile), and a warranty term on three (Philips Sonicare 3100, Oral-B iO2, Novalun).
Our Take
The Philips Sonicare 3100 HX3675/13 dual pack is the default pick: two handles with a pressure sensor, a 2-minute SmarTimer and a 2 year manufacturer warranty on the listing. For a single brush with a stated battery life and the same warranty term, choose the Oral-B iO2 (up to 4 weeks per charge, travel case); for app guidance and four modes, the Philips Sonicare DiamondClean Smart 9400.
