Grade One

We are one of the largest cleaning companies in Kent and have over 20 years' experience in our core business. As well as a formidable presence in the rest of the South East, we are also one of just a few companies that fully understand the challenges of working in London, particularly in the City for global corporate clients. We are also very strong in the education and local authority sectors, having provided services for many public bodies across the region. Whilst we have robust technology to help manage contracts and work rigidly to ISO and OHSAS standards, we are still flexible and can provide a tailored service package to suit your specific requirements.

We have a great deal of experience serving some of the biggest construction companies in the UK and the reason we continue to enjoy the business is because we understand the market. With a challenging mix of safety, flexibility, security, cost and quality, post construction cleaning is a specialist skill and one at which we excel. By working closely with the construction management from an early stage in their programme, we can implement our site teams well in advance of the requirement and even schedule and deliver multi-phase contracts to the expected hour, let alone day or week, if required.

Established in 1995 by Chairman, Jim Corrigan, Grade One have built and maintained a reputation for providing quality, professional and cost effective cleaning and support services in the South East and City of London. As a family operated business based in Kent, with a team of dedicated staff, we have the capability to provide a full range of support services including, daily cleaning, window cleaning, washroom services and additional specialised services as part of a simple, managed package to create clean environments to suit the individual needs of your business.
