Free Energy Savings – Google Ads Case Study

Client Overview

Client: Free Energy Savings
Industry: Boiler Grants 

Free Energy Savings connects eligible UK households with ECO4-approved installers to access free boiler grants. The model depends on delivering high-quality, eligibility-filtered leads that can progress quickly to installation, not just pass an initial eligibility check.

The Challenge

The ECO4 boiler grants market has several built-in challenges:

  • High demand but poor lead quality if traffic is not filtered correctly

  • Strict eligibility requirements around benefits, EPC ratings, and boiler type

  • Installer frustration caused by unqualified or slow-moving leads

  • Google Ads costs rising when campaigns prioritise volume over installability

The objective was not to generate cheap leads, but to build a reliable pipeline of install-ready opportunities.

The Goal

Use Google Ads to generate boiler-grant specific leads that met ECO4 eligibility criteria and could progress efficiently through approval and installation.

Success was measured on:

  • Cost per lead

  • Eligibility rate

Installer acceptance and feedback

The Strategy

The campaign was designed around eligibility-first intent, not scale.

Key elements of the approach included:

  • High-intent Google Ads keywords only
    (e.g. free boiler grant, ECO4 boiler scheme, government boiler grant)

  • Tight geographic targeting across eligible UK regions

  • A dedicated boiler grants landing page

  • Strong pre-qualification built into the enquiry form, including:

    • Benefit status

    • Property type

    • Boiler type, with a focus on non-condensing systems

    • EPC-related indicators

  • Clear, compliance-safe messaging aligned with ECO4 guidance

  • Continuous optimisation prioritising lead quality over volume

This campaign was optimised for:

  • Eligibility alignment

  • Installer acceptance

  • Install-ready outcomes

  • Quick-turnaround benefit-led applications, where benefit status can be rapidly verified via the DWP

Reliable ECO4 FLEX areas, focusing on councils and managing agents with fast approval times, while deliberately avoiding slow or inconsistent FLEX authorities

The Results (60 Day Period)

  • 62 boiler grant leads generated

  • Average cost per lead: £44

  • 72% of leads assessed as ECO4-eligible

  • 100% of eligible leads passed directly to installers

This resulted in:

44 install-ready opportunities delivered to installers in 60 days

Lead Quality & Installer Feedback

Installer feedback consistently highlighted the quality and installability of the leads, including:

  • Properties with low EPC ratings

  • Non-condensing boilers suitable for replacement

  • Occupants either:

    • On qualifying benefits, or

    • Suffering from eligible health conditions under ECO4 guidelines

This significantly reduced:

  • Time spent disqualifying leads

  • Installer drop-off

  • Wasted marketing spend

What We Deliberately Avoided

To protect lead quality and installer outcomes, several intentional exclusions were built into the campaign.

We deliberately avoided:

  • Low-intent or research-only traffic
    Searches that attract curiosity rather than applications were excluded to reduce time-wasting enquiries.

  • Unreliable ECO4 FLEX areas
    Councils and managing agents with slow or inconsistent approval processes were avoided, as long delays often make otherwise eligible leads commercially unviable.

  • FLEX-led applications with extended turnaround times
    Instead, we prioritised benefit-led eligibility where DWP verification enables faster qualification and progression to install.

Broad targeting without eligibility signals
Traffic was filtered using benefit, property, and boiler indicators before leads entered the system.

Why This Worked

Most ECO4 Google Ads campaigns fail because they optimise for:

  • Cheapest clicks

  • Maximum lead volume

This campaign was optimised for:

  • Eligibility alignment

  • Approval speed

  • Installer outcomes

By aligning keyword selection, landing pages, geographic targeting, and qualification logic around real-world ECO4 execution, Free Energy Savings built a predictable and scalable pipeline of install-ready opportunities.
