Alliance Cleaning | Commercial Cleaning in London & The UK

Welcome to Alliance Cleaning

Your cleaning partner for the long term

Alliance Cleaning was founded in 1998 with a clear goal: to raise the bar in commercial cleaning.

What started as a family business serving London and the home counties has grown into one of the UK’s leading contract cleaning companies, serving corporate offices, healthcare facilities, retail spaces, and specialist environments from our base in Hertford, Hertfordshire.

Our approach is straightforward.

Our contract managers look after fewer sites than the industry average, giving your workspace genuine attention. One-hour response times and mobile support teams mean problems are solved before they affect your business.

And our ISO 9001, 14001, and 45001 certifications give you verified quality, safety, and environmental standards.

What makes Alliance different?

We built our business around three principles that guide every client relationship.

View Our Pillars

We Set the Standard

Our contract managers look after fewer sites than the industry average.

Fewer contracts per manager means more focus, more care, and better outcomes for your workspace.

Standards are maintained through structured training, clear processes, and regular audits.

We Stay Proactive

One-hour response times. Mobile support teams ready to deploy.

A client portal giving you real-time access to contract data, audit reports, and service records.

We solve problems early so you never have to chase.

We Care at Every Level

People, places, and the planet are at the heart of our business.

We invest in our teams through the Alliance Pathway development programme, use sustainable cleaning products, and volunteer through our Alliance Giving Back initiative.

In 2025, we pledged 300 volunteer hours to community causes.
