Energy Cold Calling: LUN Energy's 53 Appointments

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.

Campaign Snapshot

Client: LUN Energy
Industry: Renewable Energy / Energy Assessment
Service: Cold Calling + Appointment Setting
Duration: ~60 days
Goal: Book 4-5 qualified appointments per week

Final Results-

53 appointments booked
3,890 total calls made
Consistent weekly target achievement
Weekly reporting + objection-handling improvements
Email + WhatsApp communication for faster decision-making

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

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

The account reports 53 booked appointments over roughly sixty days. That is approximately 6.2 appointments per seven calendar days across the full period; the weekly target was 4–5. The aggregate does not prove that every individual week met its target.

Weekly reporting tracked appointments, calls and feedback. Exact active calling days and a week-by-week breakdown are needed for a working-week average.

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: 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

LUN Energy’s UK campaign reports 53 booked appointments from 3,890 calls over roughly sixty days.

Results and measurement

Calls are dial attempts rather than necessarily unique prospects. The appointments are not confirmed energy contracts; closed-sales conversion is not documented.

Source: Pearl Lemon’s published campaign account. The figures are reported results, not an independently audited dataset.

How to evaluate an energy appointment-setting campaign

53 bookings ÷ 3,890 dial attempts is approximately 1.36%, or 73.4 attempts per booking. This is a calculated ratio using the published totals, not a conversion rate from unique people contacted.

Does the campaign establish a cost per customer?

No. Campaign fees, meeting attendance, contracts won and contract values are not supplied. To assess a comparable energy campaign, record those stages separately and distinguish first dials from follow-ups.

What should count as a suitable appointment?

Agree the relevant assessor or surveyor role, business fit and meeting purpose before outreach begins. A prospect accepting a time slot does not establish a completed energy assessment.
