How Buyers Score Social Value in Public Sector Tenders

“I believe public procurement shouldn’t be complicated. Every guide I write explains the process in plain English so you can bid with confidence.”
Hi, I'm Kim. If you're new to public procurement, don't worry, this guide will walk you through everything you need to know in plain English.
One of the biggest misconceptions about social value is that buyers simply award marks to the organisation making the biggest promises.
In reality, that's not how public procurement works at all.
Evaluators don't score bids based on who sounds the most impressive. They score them against published evaluation criteria, using the information you've actually included in your response.
That means a modest but well-evidenced commitment can often achieve a higher score than an ambitious promise with little detail behind it.
In this guide, I'll explain how social value is typically evaluated and what buyers are looking for when they assess your response.
Every Tender Has Its Own Evaluation Criteria
Although every procurement is different, most public sector tenders follow the same principle.
The buyer tells you what they're looking for.
Your job is to demonstrate how you'll deliver it.
The evaluation criteria may ask you to explain:
- the social value you'll deliver
- how those commitments relate to the contract
- how they'll benefit the local community
- how you'll measure success
- how you'll report progress throughout the contract
The better your response addresses those questions, the stronger your score is likely to be.
Buyers Score What You Write
This is one of the most important things to understand.
Evaluators can only award marks for the information you've included in your tender.
They can't assume you'll recruit locally simply because you're a local business.
They can't assume you support apprenticeships because you've mentioned training elsewhere.
If something matters, explain it.
Don't rely on the evaluator joining the dots.
Relevance Matters
One of the first things buyers consider is whether your commitments are relevant to the contract.
Imagine you're bidding for grounds maintenance.
A commitment to reduce fuel consumption through better route planning is clearly linked to the service.
A commitment to sponsor a sports club on the other side of the country may be worthwhile, but it's much harder for the evaluator to connect it to the contract.
The strongest responses show a clear relationship between the work you're delivering and the wider benefits you'll create.
Evidence Builds Confidence
Imagine these two responses.
Response A
"We are committed to supporting local employment."
Response B
"On our current contracts, 82% of our workforce lives within 15 miles of the sites they support. For this contract, we'll advertise all vacancies locally and aim to recruit at least two employees from within the borough during the first year."
Which response would give you greater confidence?
Buyers think the same way.
Evidence demonstrates that your commitments are realistic because you've already delivered similar initiatives elsewhere.
Measurable Commitments Score Better
Most buyers want commitments they can monitor during the life of the contract.
For example:
Instead of saying:
We'll reduce waste.
Explain:
- how you'll reduce it
- by how much
- how you'll measure it
- how often you'll report progress
Specific, measurable commitments are easier to evaluate and easier to manage once the contract begins.
Delivery Is Just as Important as the Promise
A good social value response doesn't stop at describing what you'll do.
Buyers also want to know how you'll deliver it.
Ask yourself:
- Who is responsible?
- When will it happen?
- How will progress be monitored?
- What happens if targets aren't being achieved?
The more confidence you give the evaluator in your delivery plan, the stronger your response becomes.
Quality Beats Quantity
Many suppliers think they need a long list of commitments.
That's rarely true.
Five meaningful commitments that are relevant, measurable and supported by evidence will usually score better than twenty vague promises.
Don't try to impress the buyer with volume.
Impress them with credibility.
Think Like an Evaluator
Whenever you're writing a response, imagine you're sitting on the evaluation panel.
Ask yourself:
If two suppliers made the same promise...
Why would I score one higher?
Usually the answer is because one supplier has:
- provided evidence
- explained delivery
- demonstrated measurement
- linked the commitment to the contract
- shown how the buyer will benefit
That's exactly what you should aim to include.
Don't Ignore the Scoring Guidance
Many tenders include descriptors explaining what each score means.
For example:
A high score might describe a response that is:
- comprehensive
- well evidenced
- fully addresses the requirement
- provides added value
- demonstrates low delivery risk
A lower score may refer to responses that:
- only partially answer the question
- provide limited evidence
- contain generic statements
- fail to explain delivery
Read these descriptors carefully before you begin writing.
They often tell you exactly what the evaluator needs to see.
Social Value Doesn't End When You Win
Winning the contract isn't the end of the story.
Many buyers expect suppliers to report on their social value commitments throughout the contract.
That means your promises become part of your contract management.
Before making a commitment, ask yourself:
Can we actually deliver this?
Can we evidence it?
Can we report on it?
If the answer is yes, it's probably a strong commitment.
A Quick Checklist Before You Submit
Before submitting your social value response, ask yourself:
- Does every commitment relate to this contract?
- Have I explained why each commitment matters?
- Have I included evidence wherever possible?
- Are my commitments measurable?
- Have I explained how they'll be delivered?
- Could an evaluator easily justify awarding high marks?
If the answer is yes, you're giving yourself the best possible chance of achieving a strong score.
My Final Thoughts
One of the most valuable lessons I've learned from public procurement is this:
Buyers don't award marks for good intentions.
They award marks for clear, relevant, evidence-based responses that give them confidence you can deliver what you've promised.
When writing your next social value response, don't focus on sounding impressive.
Focus on making it easy for the evaluator to understand exactly what you'll do, how you'll do it and how you'll demonstrate success.
The easier you make their job, the easier it becomes for them to award you marks.
Thanks for reading.
I hope this guide has made public procurement a little easier to understand.
