Winter is prime time for boiler installations—but if you've been relying on the same tired lead sources for years, you're likely overpaying for enquiries that never convert.
The key to growing your heating business this winter is to focus on qualified boiler replacement leads—homeowners who are actively looking for a new boiler and ready to act fast.
In this guide, we'll break down where to find high-quality leads, how to qualify them before quoting, and why installers using local property data are winning more boiler jobs in 2025.
🔍 What Are Boiler Replacement Leads?
Boiler replacement leads refer to homeowners (or landlords) looking to replace an old, faulty, or inefficient boiler. The best leads typically fall into one of these categories:
- Their existing boiler has broken down
- Their heating bills have spiked due to inefficiency
- They want to replace a back boiler or electric system
- They are renovating and upgrading systems
- They are eligible for ECO4 support or GBIS measures
These are urgent or high-intent prospects—very different from cold leads filling in a generic "quote" form online.
❌ The Problem With Most Boiler Lead Providers
Many lead gen companies promise "exclusive" or "qualified" boiler leads—but in reality, you often get:
- ❌ Leads shared with 3–5 other installers
- ❌ Price-shoppers who ghost after quoting
- ❌ Homeowners who aren't ready to buy
- ❌ Expensive pay-per-lead charges with no ROI
Platforms like Checkatrade, Rated People, or Bark are often saturated and unpredictable. They may work for some, but many heating engineers report poor return on investment—especially in competitive areas.
✅ What Makes a Boiler Replacement Lead High-Quality?
Before you buy or chase a lead, check if it ticks these boxes:
| Criteria | Why It Matters |
|---|---|
| ✅ Homeowner or landlord | They're legally allowed to authorise the job |
| ✅ Property built pre-2005 | Likely has older or inefficient system |
| ✅ EPC rating of D or below | May qualify for ECO4 or want better efficiency |
| ✅ No recent boiler upgrade (last 10 yrs) | Indicates replacement is likely |
| ✅ Winter season urgency | People don't want to wait |
If you're relying on anonymous internet leads, you'll never get this kind of insight upfront.
🏡 Smarter Lead Generation Using EPC & Property Data
Instead of buying generic boiler leads, some installers now use home data platforms that identify properties likely to need a boiler replacement.
Tools like HomeBuyerLeads let you:
- 🎯 Target recently sold homes (owners often upgrade boilers post-move)
- 🏘️ Filter by EPC rating (D, E, F, G = low efficiency)
- 🔍 Spot homes using electric heating or with outdated systems
- 📍 Focus on postcodes with high retrofit potential
This gives you boiler-ready leads—without relying on cold enquiry forms or lead resellers.
Note: While this doesn't confirm personal eligibility for schemes like ECO4, it helps you narrow your focus to homes that are statistically more likely to be interested in boiler upgrades.
💰 How Boiler Installers Are Turning Data into Booked Jobs
Here's how smart installers are generating high-converting boiler replacement leads using local data:
1. Identify High-Need Homes
Use EPC and property data to:
- Find properties with poor insulation or outdated heating
- Target households recently sold or rented
- Avoid homes with new condensing boilers already installed
2. Send Targeted Outreach
Whether it's direct mail, postcards, or leaflet drops—focus on:
- Local credibility ("We're working in your street")
- Energy cost savings ("Cut your heating bills before Christmas")
- Funding options ("You may qualify for boiler support under ECO4")
3. Offer Scheme Advice Without the Sales Pitch
Homeowners are more likely to book if they trust you're there to help—not just sell.
Include free eligibility checks, EPC reviews, or referrals to a retrofit coordinator if relevant.
📈 ECO4 and GBIS: Extra Opportunity This Winter
With ECO4 and GBIS still active in 2025, boiler replacements are part of the wider conversation on home efficiency.
While ECO4 now rarely funds a straight boiler swap, many households are still eligible for:
- First-time central heating installs
- Heating controls upgrades
- Electric-to-gas conversions (with insulation)
And with GBIS expanding to support low-cost heating measures, installers offering thermostatic radiator valves (TRVs) or smart thermostats can bundle these into small profitable jobs that open the door to future boiler upgrades.
🧠 Final Word: Stop Chasing Leads. Start Targeting the Right Homes.
This winter, there's no shortage of homes with broken, outdated, or inefficient boilers.
But the difference between a booked job and a wasted quote is lead quality.
By targeting homes based on EPC data, recent ownership, and system age, you'll reach people before they start shopping around—and without competing on price.
Want to See How Many Boiler-Ready Homes Are Near You?
Platforms like HomeBuyerLeads let you filter properties by EPC band, heating type, sale status, and postcode—so you can focus your ad spend and outreach where it counts.
You're not buying boiler leads. You're building a system that puts you in front of the right homes first.
