A practical guide to understanding what the buyer really wants and how to build a winning response.

The real focus isn't just window cleaning

When I look at this tender, the biggest insight isn't just about cleaning windows.

It's about maintaining the image and operational efficiency of Nottingham Trent University's campuses.

Yes, you'll be cleaning windows across multiple locations, including City Campus, Confetti College, Clifton and Brackenhurst.

But remember, you're also responsible for internal partitions and external signage.

It's not just about the glass — it's about what the glass represents.

Think about the university environment

Universities like Nottingham Trent are vibrant places.

They're home to students, staff and frequent visitors.

What does that mean for your submission?

It means your cleaning service must be unobtrusive yet effective.

Imagine students trying to concentrate while a window cleaner is at work.

Or a visitor's first impression of the university marred by streaky windows.

The stakes are higher than just cleaning.

Don't just promise — prove it

One thing I noticed when I worked in the public sector was that bidders often made promises without backing them up.

Evidence always beats promises.

I'd include:

  • Testimonials from similar educational environments
  • Case studies showcasing consistent service delivery
  • KPIs from past contracts showing low complaint levels
  • Evidence of staff training specific to educational settings

Pay attention to what they say

The University Estates department has made it clear this is about more than routine cleaning.

Scheduled and unscheduled cleans are both required.

This means flexibility is key.

It's not just about sticking to a schedule but being ready to respond to ad-hoc requests.

That tells me they're looking for a partner, not just a service provider.

Managing consistency across campuses

This might sound daunting.

But consistency in service delivery is crucial, especially when dealing with multi-site contracts.

I'd be thinking about:

  • How you'll ensure consistent standards across all locations
  • The systems you have in place for quality control and audits
  • Your approach to managing and training teams across different sites

The importance of a reliable team

Your team is your biggest asset.

The university will want to know you have reliable, well-trained staff.

Staffing is critical.

Not equipment.

Not chemicals.

If I were writing this tender, I'd focus on how I recruit, train and retain my team.

Think about how you add value

Every contract creates work for the client.

The best contractors reduce that workload.

How can you make life easier for the university?

Consider:

  • How you communicate with the Estates department
  • How you report and handle issues quickly
  • How you manage any potential disruptions to university life

One thing I'd keep reminding myself

This isn't about getting onto a list.

It's about being the university's trusted partner in maintaining its image and functionality.

Every answer in your submission should reflect that.

Would your approach stand up to scrutiny?

Would it satisfy the needs of a bustling university environment?

Common mistakes

Avoid submissions that:

  • Focus solely on price without demonstrating value
  • Lack evidence of past performance in similar settings
  • Ignore the importance of flexibility for unscheduled requests
  • Fail to address how you manage consistency across multiple sites
  • Overlook the significance of reliable, trained staff
  • Provide generic responses not tailored to the university's needs
  • Miss the importance of effective communication and issue resolution

My Final Thoughts

Nottingham Trent University isn't just buying window cleaning.

They're securing a partner to help maintain their reputation and operational efficiency.

With a contract value of £500,000 over two years, extendable to 2029, quality is key.

The university is looking for a service that delivers real value, not just the lowest cost.

That's what the 70% quality weighting means for your written submission.

Thanks for reading.

I hope this guide has helped make public procurement feel a little less daunting. If it has, then it's done its job.
