Cold Calling Case Study

Overview

Hey everyone  My name’s Sone, also known as Tamy, and I’m the Operations Director here at Piman, part of a the Pearl Lemon Group.

In this case study, I’ll walk you through a high-volume cold calling campaign we ran for LUN Energy, a UK-based business in the renewable energy sector. The campaign targeted energy assessors and energy surveyors with the goal of booking 4-5 appointments per week.

By the end of the two-month campaign, we delivered:

  • 53 booked appointments
  • 3,890 calls made
  • Weekly hit targets
  • Improved objection handling through real-time feedback loops
  • Consistent communication via email and WhatsApp

This write-up covers how we structured the outreach, tracked performance, and used continuous feedback to optimise results over the duration of the project.

The Objective: Appointment Setting for Energy Assessors

LUN Energy needed a scalable way to contact and book appointments with:

  • Energy assessors
  • Energy surveyors
  • Relevant decision-makers in the energy performance certification process

The aim was to connect them with individuals who could benefit from the client’s services and to do so consistently every week.

Campaign Goals

Campaign Goals

The target was simple but demanding:

4-5 booked appointments per week

Given the niche audience and the nature of cold calling, this required:

  • Volume
  • Accurate targeting
  • Script refinement
  • Strong objection handling
  • Tight communication

And that’s exactly what we built into the campaign.

Final Results: 53 Appointments in 60 Days

By the end of the campaign, the team delivered:

53 qualified appointments

Which averages: ~4–5 per week exactly on target.

We tracked everything inside weekly performance sheets, including:

  • Booked appointments
  • People who requested a call later
  • Objections and reasons for “no” responses
  • Pickup rates
  • Script effectiveness

These insights allowed us to adapt our approach weekly.

Final Results
Call Volume & Engagement

Call Volume & Engagement

Total calls made: 3,890

This included:

  • No answers
  • Invalid numbers
  • Busy signals
  • Follow-up attempts
  • Successful conversations leading to bookings

Not every all results in a pickup but volume drives results, especially in cold calling.

Weekly Reporting & Feedback Loops

Every week we provided LUN Energy with:

  • A full weekly report documenting performance
  • A list of booked appointments
  • A breakdown of objections
  • Insights on messaging improvements

These reports helped us understand:

  • Why prospects said yes
  • Why others said no
  • Which objections were recurring
  • How to refine scripts to increase conversions

This ultimately improved:

  • Objection handling
  • Call transitions
  • Appointment quality

Communication

Communication: Email + WhatsApp

We maintained communication through:

  • Email (main communication + appointment confirmations)
  • Every appointment was emailed to the client immediately.
  • WhatsApp (quick updates & clarifications)

Used for:

  • Fast responses
  • Scheduling adjustments
  • Quick questions
  • Real-time updates

This hybrid communication ensured the client was always in the loop.

Strategy Adjustments Based on Objections

Throughout the campaign, we refined:

  • The script
  • The pitch angle
  • Tonality
  • Objection responses
  • Follow-up timing

By analysing the “no” responses every week, we strengthened the messaging based on real conversations not assumptions.

This is one of the reasons the campaign maintained consistent performance for two straight months.

Lessons Learned

  • Consistency beats everything in cold calling
  • Feedback loops improve conversion rate quickly
  • Objections provide strategic direction
  • Decision-makers in the energy sector respond best to concise, factual pitches
  • Multi-channel communication improves campaign flow
  • Volume + discipline = results
