What visitors say
Based on recent Google reviewsRetrofit Kensington is a spotlessly clean boutique gym with brand-new equipment, strong free-weights setup, and a solid cardio floor. Reviewers consistently praise the instructors—Raffaele, Kimberly, Claudine, and others—for high-energy classes and skilled personal training. The sauna is available, and the South Kensington location is convenient. The space is smaller than a full-size gym, so equipment range is limited for serious athletes, but for casual lifters, class-goers, and visitors seeking a tidy, well-run facility, it's a solid choice.
Retrofit London is a members-first gym facility located in South Kensington at Petersham House on Harrington Road. The gym combines an industrial aesthetic with modern, state-of-the-art equipment and offers personal training and small group classes in a contemporary setting. Members and day pass holders can work out independently or with a trainer, and the facility provides complimentary Molton Brown toiletries plus an on-site juice bar. Operating hours run from 7am to 10pm Monday through Thursday, 7am to 9pm on Friday, and 8am to 6pm on weekends and bank holidays, with temporary memberships available for those not ready to commit to full membership.
