An insulation lead is a homeowner enquiry for loft, cavity wall, external wall or floor insulation, generated through advertising rather than bought as raw data. In the UK, exclusive real time insulation leads start from around £22 per lead. This guide covers where insulation leads come from, what a genuine one should contain, why prices vary, and how to check quality before you commit any real volume.
What an insulation lead actually is
An insulation lead is a homeowner who has asked for a quote or survey for insulation work on their property. It should be tied to a specific type of work - loft, cavity wall, external wall, room-in-roof or floor insulation - and should carry enough property detail for you to know whether the job is worth calling first. It is not a name from a database, and it is not someone who was cold-called and agreed to "have someone come round".
Where insulation leads come from
- Own comparison websites, Google Ads, paid social and directories or shared marketplaces are the four places a insulation lead can come from.
- What the homeowner was asked before the enquiry was submitted is what decides its quality.
- That enquiry is the lead you buy.
- Own comparison websites, where a homeowner requests insulation quotes and submits their details.
- Google Ads, where a search for insulation quotes or grant eligibility leads to a form.
- Paid social on Facebook, Instagram and TikTok.
- Directories and shared marketplaces, including grant-focused lead exchanges, where the same enquiry can be sold to several installers.
Insulation advertising has drawn particular regulatory scrutiny in the UK, especially around grant-funded schemes, so it is worth checking that whichever channel your provider uses is run compliantly and does not overstate eligibility or funding.
Exclusive versus shared insulation leads
An exclusive lead is sold once, to you. A shared lead is sold to several installers, usually cheaper per lead, but the homeowner ends up fielding several calls and the surveyor who gets there first, or offers the lowest number on the phone, tends to win the job. Because insulation jobs often involve grant paperwork and eligibility checks, being first to speak to the homeowner matters more than in a straightforward retail purchase.
Real time versus aged leads
A real time insulation lead reaches you within minutes of the enquiry being submitted. An aged lead can be days, weeks or months old, and is typically sold cheaply in bulk. Insulation enquiries linked to grant schemes go stale quickly, because scheme rules and household eligibility can change, so an aged lead risks being called on a scheme that has already moved on or a household that has since found another installer.
What a genuine insulation lead should contain
At minimum, an insulation lead should include:
- Full name and a checked UK phone number
- Property postcode and property type (house, bungalow, flat)
- Insulation type of interest (loft, cavity wall, external wall, floor)
- Whether the property is owner-occupied or a private rental
- Any grant or funding route being asked about, if relevant
- Source and timestamp of the enquiry, with confirmation of consent
What insulation leads cost and why prices vary
UK insulation leads start from around £22 per lead. Price is driven by exclusivity, volume, the type of insulation work, the area, and whether the lead relates to a grant-funded route, which typically requires more qualifying questions to check eligibility before the lead is passed on. Providers may also offer pay-per-appointment for a higher fee, where the enquiry is qualified and a survey booked directly into your diary.
Seasonal demand for insulation leads
Insulation enquiries tend to rise as the weather turns colder, when homeowners notice draughts and high heating bills and start looking for a fix. Demand typically builds through autumn and peaks over winter, before easing off in spring and summer when insulation is less front of mind. Grant-related campaigns can also see spikes tied to scheme announcements or deadlines, such as increased interest as ECO4 approaches its 31 December 2026 close, so it is worth asking a provider how they expect volume to move as that date approaches rather than assuming a flat weekly rate for the rest of the year.
Insulation lead sources compared
| Source | Exclusivity | Speed | Typical price signal | Watch for |
|---|---|---|---|---|
| Own comparison websites | Usually exclusive | Real time | Mid to higher | Confirm the provider owns the site and asks proper eligibility questions |
| Google Ads and paid social, run direct | Exclusive | Real time | Mid to higher | Check how grant eligibility claims are worded in the ads |
| Grant-focused directories and marketplaces | Often shared | Real time to same-day | Lower | Several installers may already have the same enquiry |
| Aged data and bulk lists | Shared, often resold | Delayed | Lowest | Eligibility and consent may be out of date |
How to judge insulation lead quality in the first two weeks
- Contact rate: what share of insulation leads you actually reached.
- Survey booking rate: Did a survey get booked?
- Rejection rate: how many were replaced under the rejection policy.
Track contact rate, survey booking rate and rejection rate. Because insulation often involves grant eligibility, also check what proportion of leads turn out to be genuinely eligible on first contact - a high rate of ineligible leads points to weak qualifying questions upstream. A good provider offers a rejection policy so a wrong number, duplicate or non-genuine enquiry is replaced rather than charged.
Contact rate and follow-up practice
Call every insulation lead within five minutes of it landing where possible, and follow up with a text and email within the hour if the first call is missed. Because scheme rules and household circumstances can change quickly, insulation leads lose value faster than some other home improvement leads, so speed of follow-up matters more here than in most sectors.
Pay per lead, pay per appointment or revenue share
Insulation providers typically offer pay per lead as the entry model, with pay per appointment available at a higher fee for installers who want a survey already qualified and booked into the diary rather than a raw enquiry to chase. Because a meaningful share of insulation work runs through grant-funded routes, some providers also structure pricing around the volume of pre-qualified, eligibility-checked leads rather than a flat per-lead rate, since the qualifying work upfront reduces wasted call time on households that turn out ineligible. Whichever model you choose, agree in writing what counts as a qualifying lead so there is no dispute later about whether an enquiry should have been screened out.
How to switch insulation lead providers without a coverage gap
Run a new provider alongside your existing one for two to four weeks before switching fully, particularly if some of your volume comes from a grant-funded route where eligibility rules can shift. Ask the new provider exactly how they screen for scheme eligibility before a lead is sold, and compare the proportion of genuinely eligible leads against your current provider over the trial period rather than relying on price alone. Keep a clear record of which lead came from which source so a dip in survey bookings can be traced to the right cause.
Red flags when choosing an insulation lead provider
Be cautious of a provider who cannot explain how eligibility is checked before a lead is generated, who will not confirm exclusivity in writing, who has no rejection policy, or whose marketing implies a grant is free money rather than a funded scheme with eligibility criteria. Confirm the provider runs campaigns in line with ASA and ICO rules, since insulation and grant advertising is an area regulators have acted on.
