Red flags: asbestos contractors without RERA registration

Why the RERA matters in the first place

The RERA (Registro de Empresas con Riesgo por Amianto) is the register of companies authorised to work with asbestos. Real Decreto 847/2026, which replaced Real Decreto 396/2006 at the end of October 2026, keeps the core rule: only RERA-registered companies may demolish or remove asbestos-containing materials, under a plan de trabajo approved by the labour authority of the province where the work is done. In Andalusia the register is kept by the Junta de Andalucía.

So the first question for any offer is not "how much?" but "who will actually remove the asbestos, and under which plan?" Our guide on the RERA register explains the system in more depth.

A transparent note on how we work

Because this post is about red flags, it is fair to say clearly how our own set-up works. Retirada de Uralita Málaga is not registered in the RERA. The asbestos removal is carried out by a RERA-registered company that works as our subcontractor, under its own approved work plan; we coordinate the rest of the demolition and the job as a whole.

That model – a general contractor coordinating, a registered specialist executing the asbestos part – is legitimate and common. What is not legitimate is a contractor who removes asbestos itself without registration, or who uses the word "subcontractor" vaguely without being able to show a registered company and a work plan. The difference is in the paperwork, and you are entitled to see it.

Red flags in the first conversation

Many problems can be spotted before anyone visits the site:

• No mention of RERA, a work plan or protective measures when you say the word "uralita".
• "It's only fibre-cement, it isn't dangerous" – said about old sheets without any analysis.
• "We'll do it this weekend" – an approved work plan and prior notification of the start of works take preparation; instant start dates are a sign that step is being skipped.
• Cash only, no written quote, or a quote that does not separate the asbestos part from the rest.
• Vagueness about who does the work: "a colleague", "our team", without a company name you can check.

Red flags in the method

The way someone proposes to remove the material tells you a great deal:

A legitimate removal is slower and quieter than people expect: fixings out, whole sheets down, wrapped on the spot. That is why the job on our uralita removal page is planned, not improvised.

Red flags in the waste

Waste is where shortcuts save the most money – and cause the most trouble for the owner afterwards. Asbestos cement is hazardous waste 17 06 05* and may not be mixed with other waste (Ley 7/2022, art. 30.1). Watch for:

• Sheets going into the same skip as bricks and tiles.
• Offers to "take it away in the van" with no destination named.
• Material left wrapped on your plot "for later collection" with no date.
• No delivery documents from an authorised manager at the end.

Without those documents you have nothing to show where the asbestos from your property went – not to a buyer, not to the community, not to the town hall. The cleaner route is set out in our guide on asbestos waste disposal in Spain.

Why a suspiciously low price is a warning

An asbestos removal quote has unavoidable components: a registered company, a plan de trabajo, protective equipment, controlled handling, separate transport and delivery to an authorised manager. If an offer is far below the others, one of those components is probably missing. Our sister site explains how to compare demolition quotes line by line, and the same logic applies to asbestos.

Ask every bidder to state in writing which company is RERA-registered, who prepares the work plan and where the waste goes. The answers usually make the price differences understandable.

Red flags when you are not on site

Owners who live abroad are a natural target for shortcuts, simply because nobody is there to see the roof come down. A few signs deserve extra attention in remote jobs:

• Photos arrive only of the finished, empty roof and never of the work in progress.
• The job is "already done" before you have seen any work plan or company name.
• The caretaker or neighbour who opened the gate was asked to stay away "for safety" but no zone was ever marked.
• The invoice lists "removal of old roof" with no reference to asbestos, the registered company or the waste.

The remedy is simple: ask for the documents before the start date, agree on photo updates during the job and keep the waste delivery papers with the property file.

What to ask for before signing

1. The name of the RERA-registered company that will remove the asbestos.
2. Confirmation that it will prepare and file the plan de trabajo for your site.
3. A written method: wetting, removal of fixings, whole sheets, wrapping.
4. The waste route: separate transport and delivery to an authorised manager, with documents for you.
5. What happens afterwards: new roof, temporary cover or demolition of the structure.

In a community of owners, the administrador should keep these documents for the file; our page on asbestos in communities of owners explains why. For the full list of checks, use our asbestos removal contractor checklist.
