Your phone rings on a Tuesday afternoon.
The caller sounds official.
They might claim to be from "the national insulation database" or "the local energy council."
They tell you your loft insulation is out of date.
They claim it might even be dangerous to your health.
They offer a "completely free, no-obligation health check" for your loft.
It sounds like a helpful service for any homeowner.
In reality, it is often the start of a sophisticated scam.
At ComfySeal Ltd, we see the aftermath of these calls far too often.
This guide will help you spot these scammers before they set foot in your home.
The Script: How the Scam Begins
Scammers rely on authority and urgency.
They usually target specific postcodes across the UK.
The caller often uses a script designed to trigger worry.
They might mention that your fibreglass insulation is now "illegal."
Or they claim it causes lung irritation and mold growth.
These are high-pressure tactics used to get a salesperson through your door.
Legitimate professional loft insulation installers do not operate this way.
We do not cold-call homeowners to demand "safety inspections."
If an unsolicited caller tells you your home is a health hazard, hang up.
The "Toxic Insulation" Myth
One of the most common lies involves your current insulation material.
Scammers often claim that old mineral wool or fibreglass is toxic.
They may falsely cite the British Lung Foundation to gain credibility.
They want you to believe your loft is a ticking time bomb.
In truth, mineral wool is a safe, standard material used in millions of homes.
While it can be itchy to handle, it is not a "poison" requiring urgent removal.
These scammers invent a problem so they can sell you an expensive solution.
Usually, that "solution" is overpriced spray foam insulation.

Red Flags: How to Spot a Rogue Surveyor
Knowing the warning signs can save you thousands of pounds.
Watch out for these specific red flags during a phone call:
1. Unsolicited Contact
If you didn't ask for the call, be suspicious.
Legitimate companies rarely cold-call for "surveys."
2. The "Government Representative" Claim
Scammers love to pretend they work for the council or a government scheme.
They might use names that sound official but don't actually exist.
3. High-Pressure Tactics
They will push for a "surveyor" to visit the same day or the next morning.
This prevents you from doing your own research or talking to family.
4. Age-Based Targeting
They often ask if you are over 60 or 70 years old.
They target vulnerable people who might be more trusting of "official" callers.
5. Hidden Identity
They often refuse to provide a physical office address or a website.
If they won't give you a landline number, something is wrong.
The Spray Foam Trap: A Costly Mistake
The goal of the "free survey" is almost always to sell spray foam.
The salesperson will enter your loft and "discover" damp or mold.
They will then offer to spray the underside of your roof with foam.
They claim it is the latest technology for loft insulation UK homes need.
However, improper spray foam can lead to serious structural issues.
It can trap moisture against your roof timbers, leading to "rotting timbers."
Even worse, it can make your home impossible to sell.
Many mortgage lenders will refuse to lend on properties with spray foam.
Removing it can cost double or triple the original installation price.

Why They Want to Get Inside Your Home
Once a "surveyor" is in your loft, they have the upper hand.
They might show you photos of mold or damp on their phone.
But how do you know those photos were taken in your loft?
Some scammers carry spray bottles to create "wet patches" on your wood.
They use these fake problems to justify a £5,000 or £10,000 quote.
They will offer a "special discount" if you sign a contract immediately.
Never sign anything on the day of a survey.
A real professional will provide a written quote and give you time to think.
How to Protect Yourself and Your Community
If you receive one of these calls, you can take control.
Hang up immediately. You do not owe a cold-caller your time.
Do not share personal details. Never confirm your age, address, or bank details.
Report the scam. Contact the Citizens Advice Consumer Service.
You can also report the number to Action Fraud.
Tell your neighbours and elderly relatives about these tactics.
Awareness is the best defence against these predatory companies.
