5 Best Commercial Cleaning Services in London (2026)

Clean All Crew Ltd is a London property-maintenance company that pairs commercial and office cleaning with commercial kitchen cleaning, carpet cleaning, gutter and pressure washing under one contract. Now in its tenth year, it runs a team that has stayed largely intact since 2015, and staff are CRB and DBS checked, a detail that matters when cleaners have out-of-hours access to a business's premises. Its scope covers everything from a routine office clean to a post-building-works commercial reset.

Perfect Cleaning is a London cleaning company offering carpet cleaning, house cleaning, end-of-tenancy work and office contract cleaning, and it carries the largest review base of any business on this page. Its site lists regular cleaning for commercial and domestic buildings as one of its core lines, alongside spring cleaning and upholstery work, positioning it as a generalist that also does contract office work rather than a specialist commercial-only shop.

West Clean Ltd is a London cleaning company covering both residential and commercial properties, with janitorial service listed alongside house cleaning, carpet cleaning, window cleaning and upholstery work in its service range. Its own site markets it as a multi-purpose cleaner for homes and businesses, and one review describes it turning around a large commercial-scale job, cleaning a four-storey building after nearby construction work, with a five-person team on a next-day basis.

Hoxton Commercial Cleaning is a London company that works exclusively with businesses, listing offices, schools, retail, gyms, restaurants and warehouses as its sectors. It offers contract cleaning, deep cleaning, after-builders cleaning, high-level and hard-floor cleaning, and its own site states it is fully insured and compliant, with an eco-friendly product line. Unlike several names on this list, it does not appear to take on domestic jobs, which shows in a review base built entirely around office and warehouse cleaning.

Dazzle is a commercial and office cleaning company based in Shoreditch, working across sectors from co-working spaces and law firms to embassies, retail and healthcare, with services covering daytime and out-of-hours office cleaning, communal-area cleaning, washroom management and reception support. It runs on a named account-manager model, several reviewers mention a specific contact who checks in regularly, and its site states it pays the Real Living Wage, which reviewers link to staff consistency on site.
