The UK Cleaning Industry Is Booming — But Buyer Beware

Did you know the UK commercial cleaning industry is now valued at over £55 billion, making it one of the largest service sectors in the country? It employs over 700,000 people and serves virtually every type of business, from GP surgeries to data centres.

But size doesn't equal quality — and in a fragmented market, standards vary enormously.

The Accreditation Landscape

The cleaning industry has several professional bodies and accreditation schemes:

  • BICSc (British Institute of Cleaning Science) — the leading professional body, offering training and certification for operatives and managers
  • ISO 9001 — quality management accreditation relevant to cleaning contractors
  • Safe Contractor / CHAS — health and safety pre-qualification schemes
  • Living Wage Foundation — employers committed to paying above the minimum wage

Only a minority of UK cleaning companies hold meaningful accreditations. Many operate with no external oversight whatsoever.

What the Data Shows

Industry surveys consistently find:

  • Over 60% of businesses have changed cleaning provider in the last 3 years
  • The most common reason is quality dropping after the initial contract period
  • Price is the primary selection criterion for 70%+ of buyers — often to their detriment

The Real Cost of Going Cheap

A low-cost cleaning contract often means:

  • Operatives paid minimum wage with high turnover
  • Minimal training and supervision
  • No investment in equipment or eco-certified products
  • Quality that deteriorates after the first few months

How to Choose the Right Provider

  1. Ask for proof of BICSc training or equivalent
  2. Check for public liability insurance (minimum £5m)
  3. Request references from similar-sized businesses
  4. Understand exactly what hours and tasks are included
  5. Ask how quality is monitored ongoing — not just at the start
