A practical guide to understanding what United Utilities really wants and how to build a winning response.

Don't think about the testing. Think about trust.

At first glance, this looks like a straightforward engineering service.

But United Utilities isn't just buying emissions testing.

They're buying confidence that their CHP engines, boilers and flare stacks are compliant and reliable.

That's a different mindset entirely.

The framework covers annual, MCERTS-compliant combustion emissions testing and analysis across 9 Anaerobic Digestion facilities in the North West.

But what they're really looking for is a partner who can ensure compliance without causing disruptions.

Understand the framework's purpose

This isn't a single contract to test emissions once or twice.

It's a framework agreement setting the terms for future orders over several years, potentially until 2035.

Winning a place on the framework is your first goal.

Call-off contracts for the actual testing will follow, but they aren’t guaranteed.

You'll need to show why United Utilities should pick you for both the framework and any future work.

Pay attention to what they say

United Utilities is clear about their priorities.

They need MCERTS-compliant testing.

This is non-negotiable.

If I were writing this tender, I'd make sure my submission clearly details how my services meet these standards.

They’ve also mentioned the need for testing on various equipment, including CHP engines, boilers and flare stacks.

I'd ensure my proposal shows flexibility and capability across all these areas.

Think about the people who rely on you

The real users of your service are the engineers and site managers at these facilities.

Their jobs depend on having reliable, compliant equipment.

If I were in their shoes, I'd want to know:

  • Can this supplier conduct tests without disrupting operations?
  • Do they understand the importance of compliance in our processes?
  • Will they communicate findings clearly and promptly?

That’s what I’d focus on.

Show how you'll make their lives easier.

Evidence always beats promises

When I worked in the public sector, I saw lots of big promises.

What set the best submissions apart was evidence.

If you have it, use it.

Consider including:

  • Case studies of similar work
  • Client testimonials
  • MCERTS certification details
  • Performance data from past projects

These will carry more weight than vague assurances.

Remember, consistency is key

This framework runs potentially until 2035.

That's a long time to maintain standards.

I'd be looking for a supplier who can demonstrate a track record of consistent delivery over similar terms.

How do you manage staff turnover, equipment failures or sudden demand spikes?

Show how you'll maintain quality and compliance over the entire framework duration.

A framework isn't a guarantee of work

Winning a spot on the framework is just the start.

Call-offs are where the real work is, but they require you to be seen as the easy choice.

Make sure your pricing is competitive, but also that you're easy to work with.

Reliability and a good track record can make the difference when United Utilities decides who to call on.

Be ready for further competition

Some call-offs may require further competition among framework suppliers.

This means you'll need to respond quickly to mini-competitions.

Ensure your team is prepared to turn these around efficiently.

It’s about being ready to prove, again, why you’re the best choice.

Common mistakes

Avoid submissions that:

  • Ignore the importance of MCERTS compliance
  • Fail to demonstrate flexibility across different equipment types
  • Overlook the need for clear communication with site managers
  • Lack evidence of past performance
  • Don't show a clear plan for maintaining quality over the framework's life
  • Assume work is guaranteed by being on the framework
  • Provide unclear pricing structures
  • Miss deadlines for mini-competitions

My Final Thoughts

United Utilities is looking for more than just a testing service.

They want a partner who can ensure compliance and reliability, without adding to their workload.

This framework is valued at £1,083,333, running initially from 2027 to 2030, with an option to extend to 2035.

The longer term means they'll need to trust their suppliers implicitly.

Quality will likely carry significant weight in the evaluation.

Focus your written submission on showing why you're the most reliable choice for the long haul.

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.
