Writing Case Studies That Win Contracts

Case studies are where SMEs win or lose tenders. A good case study proves you can deliver. A weak one makes you look inexperienced - even if you've been in business 20 years. This guide shows you how to write case studies that evaluators actually want to read.

Struggle to write about your own work? Many tradespeople are brilliant at the job but modest about selling themselves. MyBidTeam transforms your project notes into compelling case studies.

Why Case Studies Are Worth 30%+ of Your Score

Here's how evaluators think:

Claims are cheap. Anyone can say "we deliver quality work"
Evidence is expensive. Only companies who've actually done it can prove it
Risk reduction. Evaluators are scared of picking a supplier who fails

A strong case study does three things:

Proves capability - You've done similar work before
Demonstrates approach - Shows HOW you work, not just THAT you work
Reduces perceived risk - Makes the evaluator confident in choosing you

Evaluator insight: When I'm evaluating tenders, I'm asking one question: "Will this company deliver what they promise?" A specific case study with names, numbers, and outcomes answers that question. Vague statements don't.

The 6-Part Case Study Structure

Every case study should answer these six questions. Miss any of them and you leave marks on the table.

WHO was the client?

Client name, sector, location. If confidential, describe the type: "A 400-pupil primary school in Leicestershire"

WHAT did you do?

Scope of work, contract type, contract value, duration. Be specific: "Full rewire of 3-storey Victorian building, £47,000, 8 weeks"

WHAT made it challenging?

The constraint, complexity, or difficulty. This shows you can handle problems: "Building remained occupied throughout, requiring out-of-hours work"

HOW did you solve it?

Your approach, innovation, extra mile. Named people help: "Project Manager Sarah coordinated with building users daily"

WHAT was the result?

Measurable outcomes. Numbers beat adjectives: "Completed 3 days early, zero defects, 15% energy saving documented"

CAN we contact them?

Reference availability. "Reference available on request" or named contact. Always ask permission first.

How to Capture Case Studies (Conversation Method)

Most tradespeople hate writing about themselves. "We just did the job" isn't false modesty - it's how you work. But evaluators need the story.

Here's a simple conversation you can have with yourself or a colleague after each significant job:

10-Minute Case Study Capture

Question 1: The basics

Who was the client? What was the job? Roughly what value? When?

Question 2: What made it tricky?

Was there anything that made this harder than normal? Tight deadline? Access issues? Occupied building? Technical complexity?

Question 3: How did you handle it?

What did you actually do to solve that? Weekend working? Extra coordination? Specialist equipment?

Question 4: What was the outcome?

Did you finish on time? Any defects? Did they give feedback? Any numbers - savings, speed, satisfaction?

Question 5: Would they recommend us?

Can we use them as a reference? Who should we contact?

Record the answers in any format - notes app, voice memo, even a text message to yourself. You can polish it later.

Pro tip: Capture case studies within 2 weeks of completion. Details fade fast. A 10-minute capture while it's fresh beats a 2-hour struggle to remember months later.

Before/After: Raw Notes to 5/5 Case Study

Here's how to transform rough capture notes into a winning case study.

Raw Capture Notes

Client: Westfield Primary School
Job: Replaced full heating system over summer holiday
Value: £38k
When: July-Aug 2024
Tricky: 6-week deadline, asbestos in old pipes, school needed access for summer club
Solution: Worked weekends, brought in licensed asbestos contractor, coordinated around summer club times
Result: Finished 3 days early, no disruption to summer club, 15% energy saving
Reference: Yes - contact Sarah Williams (Business Manager)

Transformed Case Study (Scores 5/5)

"Client & Contract: Westfield Primary School, Leicestershire. Full heating system replacement including boiler, pipework, and radiators across 12 classrooms, 2 halls, and administration areas. Contract value: £38,000. Duration: 6 weeks (July-August 2024).

Challenge: This project required completion within a strict 6-week summer window while the school's popular summer club continued to operate, serving 80+ children daily. During strip-out, we discovered asbestos-containing material in the original pipework - not identified in the pre-contract survey.

Our Approach: Project Manager Dave Mitchell coordinated daily with the Summer Club Manager to schedule noisy works around activity times. We deployed weekend working (4 Saturdays) to recover time lost to asbestos remediation. Our licensed asbestos removal partner (ACE Environmental) mobilised within 72 hours of discovery, completing removal in 5 days.

Dave implemented a zoned heating strategy, commissioning the main hall system first to provide backup warming for Summer Club activities during the cooler final week of August.

Result: Project completed 3 working days ahead of schedule. Zero disruption to Summer Club operations - 100% attendance maintained throughout. The new A-rated condensing boiler and TRV-controlled radiators have delivered documented 15% energy saving compared to the previous year (verified by school's utility bills).

The school subsequently commissioned us for bathroom refurbishment works (£12,000, completed January 2025).

Reference: Sarah Williams, Business Manager, Westfield Primary School. Contact details available on request."

Notice what changed:

Numbers added: 12 classrooms, 80+ children, 72 hours, 4 Saturdays, 15%
Names added: Dave Mitchell, ACE Environmental, Sarah Williams
Problem-solving shown: Not just "worked weekends" but WHY and HOW
Outcome quantified: 15% energy saving with source (utility bills)
Repeat business mentioned: Strongest evidence of satisfaction

Case Study Template

**Client & Contract:** [Client name], [Location]. [Brief description of work scope]. Contract value: £[amount]. Duration: [timeline]. **Challenge:** [Describe what made this project difficult. Tight deadline? Technical complexity? Occupied building? Access constraints? Budget pressure?] **Our Approach:** [Named person, e.g., "Project Manager Jane Smith"] [specific action taken]. We [what you did differently or additionally]. [If relevant: specific coordination, weekend working, specialist partners, innovative solutions]. **Result:** [Measurable outcome 1, e.g., "Completed 2 days ahead of schedule"]. [Measurable outcome 2, e.g., "Zero defects at handover"]. [Measurable outcome 3, e.g., "Client satisfaction score 9.5/10"]. [If applicable: repeat business, extended contract, referrals]. **Reference:** [Name], [Role], [Organisation]. Contact details available on request.

Word Count Guidance

Adjust based on the tender's word limit:

Limit	Approach
100-150 words	Client, scope, challenge, result only. One sentence each.
200-300 words	Full structure, concise. One paragraph per section.
400-500 words	Full structure with detailed approach and multiple outcomes.
No limit stated	Aim for 300-400 words. Concise beats long.

7 Case Study Mistakes That Lose Marks

1. Wrong relevance

A £500k hospital build doesn't prove you can do £30k school cleaning. Match scale and type.

2. Too old

Most tenders ask for examples from the last 3-5 years. A 2018 project looks dated in 2026.

3. No challenge

"We did the work to spec" shows nothing. What was DIFFICULT? How did you handle it?

4. No numbers

"The project was successful" vs "Completed 3 days early with zero defects" - which scores higher?

5. No names

"Our team delivered" vs "Project Manager Sarah Thompson coordinated..." - specifics win.

6. Can't verify

"A major council" isn't verifiable. Name them (with permission) or provide enough detail to be credible.

7. Wrong length

50 words for a 500-word question = wasted opportunity. 1000 words for a 200-word limit = may be truncated.

Building a Case Study Library

As you accumulate case studies, tag them so you can quickly find the right one for each tender:

Tag Category	Example Values
Sector	Education, Healthcare, Housing, Local Authority, Emergency Services
Work Type	Installation, Maintenance, Refurbishment, Emergency, Planned
Value Band	Under £25k, £25-50k, £50-100k, £100k+
Setting	Occupied building, Live environment, Sensitive site
Challenges	Tight deadline, Coordination, Technical complexity, Access constraints
Outcomes	On time, Under budget, Client satisfaction, Energy saving, Repeat work

When a tender asks for "experience delivering maintenance services in occupied educational buildings" - you can instantly find your tagged case studies that match Education + Maintenance + Occupied Building.

Quick Reference: Case Study Checklist

Before using any case study in a tender, verify:

☐ Relevant to this tender (similar scale, sector, work type)
☐ Recent enough (typically last 3-5 years)
☐ Client named or clearly described
☐ Contract value stated
☐ Challenge/difficulty included
☐ YOUR approach explained (not just "we did it")
☐ Named person(s) involved
☐ Measurable outcomes (numbers, timescales)
☐ Reference available
☐ Within word limit
