Client Testimonial

I want to thank Assertio and most particularly Marcello, who has been so helpful and professional in our Covent Garden shop and also in our newly open location in Bluewater. I rarely met someone so dedicated to his job and to his clients. He even thought about wishing me my birthday… This is a true sales man with extremely rare work ethic and you are very lucky to have such a valuable member working with you. – Emeline Denis – Office Co-ordinator – Rabeanco –

Cafes, Bars, Pubs and Restaurants

Catering facilities are notoriously difficult to keep clean, but our specialist cleaning services will have your premises looking like new in no time.

Commercial Kitchens

Maintaining cleanliness in commercial kitchens is an essential factor in food hygiene and healthy and safety. Our stringent cleaning processes ensure that all of those hard-to-reach places are dealt with on a regular basis.

Domestic Homes

Are you often simply too tired to start dusting and vacuum cleaning after a long day at work? Well, you don’t have to; just give us a call, and we’ll have your house looking like a palace in no time.

Food Processing Plants

The legal regulations surrounding food processing plants can leave some businesses vulnerable to closure from food safety professionals, but our detailed cleaning services will keep your premises on the right side of the law.


The recent outbreaks of dangerous bacterial infections mean keeping hospitals clean and sanitary is hugely important. Our use of detailed cleaning processes and the latest cleaning chemicals reduces potentially harmful bacteria to minimal levels. 


We understand that even the smallest amount of contaminants in a laboratory can affect the results of research projects and scientific tests. We use proven cleaning methods that keep these areas clean whilst minimising the disruption to operations.


Offices are notorious environments for the build up of potentially harmful bacteria that puts your workers at risk of illness. We have perfected the art of maintaining high levels of cleanliness in offices whilst allowing business operations to continue unaffected.

Public and Private Transport

Our cleaning operatives are experienced in the cleaning of buses, taxis and a wide range of transport options. We use a range of specialist cleaning methods and chemicals that are specifically designed for vehicles. 

Retail Establishments

Whether it’s a small shop or a department store, our skilled cleaning operatives know exactly what it takes to create inviting shopping environments for your customers. 


Any building that houses hundreds of children is susceptible to grime, litter and bacteria, but our tried and tested cleaning procedures are designed to maintain a sanitary environment in which young minds can develop to their full potential. 

Specialised Cleaning Services

There are times when certain circumstances call for a very specialised cleaning service, and that’s why we have perfected a range of procedures and chemical combinations for that purpose. The cleaning of upholstery, mattresses, carpets and awnings is something people can find rather difficult with standard cleaning products, but we employ the latest techniques and chemicals to get these items looking like new in no time. We are also here to tackle the urban blight of graffiti. Graffiti is obstructive and unsightly, and it can affect your business if it is left on your premises for too long.

Happy Cleaners, Happy Customers

At Assertio Services, we pride ourselves on keeping our team of skilled and professional cleaners happy. To us, the satisfaction of our employees is insurmountable. We know that as long as our cleaners are pleased with their jobs they will continue to work hard for you. We respect our employees and their passion for doing their jobs well.

We are always looking for those who are determined to provide their absolute best to our customers. If you are interested in joining our outstanding team, telephone us at 084 4800 6806. You may also email us with your resume and availability at
