Overview

Swift Choice Limited is a well-established linen hire and laundry services provider based in London, with over 10 years of experience in the hospitality sector. The company is a member of the NLG, the UK Housekeepers Association and the TSA, serving a wide customer base including hotels, restaurants, healthcare facilities and leisure operators.

The Challenge

Swift Choice faced operational inefficiencies driven by:

  • Inaccurate chemical dosing, leading to inconsistent wash results
  • Extended cycle times and elevated temperatures required to compensate and maintain wash quality
  • A lack of service and support from the incumbent supplier

These issues resulted in increased energy usage, longer processing times and reduced overall productivity.

The Solution

WSI introduced a tailored solution involving:

  • Installation of reliable, innovative commercial chemical dosing equipment with an online monitoring platform
  • Use of test kits for accurate, measurable control of chemical dosing on laundered textiles and wastewater
  • A review of wash programmes to streamline efficiency and improve wash quality

This enabled:

  • Precise and consistent chemical dosing
  • Optimised wash processes and wash quality
  • Reduced dependence on higher temperatures and longer cycles
Swift Choice's previous dosing setup: rows of mismatched pumps mounted on a wooden batten with tangled tubing
Before: the incumbent supplier’s dosing setup.

After: the WSI dosing and monitoring installation.

The Results

Lower Energy Consumption

Analysis comparing pre- and post-installation data shows gas consumption reduced consistently by ~20% when washing the same volume of textiles, because cycle times are now shorter and run at lower temperatures.

Shorter Cycles and Greater Capacity

87% of wash cycles in use have now been reduced in time by 37%, achieved by removing some prewashes, excessive cycle times and extra rinses.

Across the majority of wash cycles, that reduction saves 367 hours in a month — the equivalent of 881 additional loads processed within the same timeframe, hugely increasing wash capacity.

Improved Wash Quality

  • Significant reduction in rejects and yellowed items
  • Consistently high wash quality
  • Improved operational confidence and reliability

In Their Words

“Wash quality has improved drastically. The results are much better now.”

— Natalia, Laundry Manager

“We’ve noticed everything is much more efficient now.”

— Tharwat, Director

“We’re getting through work much quicker and the wash quality is better.”

— Bassam, Director

The Impact

The implementation of WSI’s dosing and monitoring solution has transformed Swift Choice Limited’s laundry operations. The business has achieved:

  • ~20% reduction in gas consumption
  • 37% shorter cycle times across 87% of wash cycles
  • 367 hours saved each month, equivalent to 881 additional loads
  • Improved wash quality and fewer rejects

Swift Choice now operates more efficiently, more cost-effectively and to higher service standards, reinforcing its position as a leading laundry provider in the London hospitality sector.
