Established in 1983, we clean hundreds of offices in London every day. Our clients range from large international organisations to micro-companies – and many of them have been with us for years.

There’s a quick way to do things and there’s the best way. We do things the best way. And by using advanced, eco-friendly cleaning methods we are often able to save you time and money, as well as producing superior results.

We aim to reduce the amount of time you spend managing your cleaning contract by training our staff to use their initiative. We’ll deal with unexpected situations as they arise, and act swiftly and efficiently to resolve issues.

We’ve been cleaning spaces like yours in London since 1983

That’s more than 30 years experience. From the biggest to the smallest, inside and out, we clean every workplace to the same high standard.

Office Cleaning

Daily office cleaning is the foundation on which our business is built, and we believe in nothing short of perfection.

IT and office Equipment Cleaning

From computers to water coolers; if it’s got a plug on it we’ll clean it for you – correctly and carefully.

Window Cleaning

City grime quickly builds up on windows, spoiling the view both inside and out.

Post Build / Refurbishment Clean

When you’ve had the builders in, things can get a little topsy-turvy. Deep Kleen will make it ‘business as usual’ in no time.

Carpet Cleaning

Regular cleaning with the Texatherm™ system keeps your carpets the way you want them to be – immaculate.

Blind Cleaning

High-tech ultrasonic treatment makes cleaning blinds a breeze – and breathes fresh air into your workplace.

Upholstery Cleaning

Don’t deter visitors with grubby reception furniture; let our trained technicians work their Deep Kleen magic.

Green Cleaning Company

We see it as essential that all office-cleaning processes and materials are as eco-friendly as possible.

"Our company has used Deep Kleen Services for over 10 years now and would not hesitate in recommending their services.  As a working office it is not ideal to have cleaners in during the day, so Deep Kleen are trusted with the responsibility of opening the building in the early hours so that all cleaning is undertaken before the working day starts.  In addition to the routine cleaning, Deep Kleen take care of all our extra cleaning requirements, such as carpet cleaning, window cleaning and jet washing the outside of the building, all carried out professionally at very competitive prices."  - Trevor Hamshere
