A practical guide for housing associations, facilities managers, local authorities, and anyone responsible for solid fuel appliances across multiple sites.
Search for a chimney sweep in Northamptonshire, Bedfordshire or Milton Keynes and you'll find plenty of options. Some are fully qualified and accredited. Others are not. From the outside, it can be hard to tell the difference — and that's exactly the problem.
This isn't a dig at anyone. It's just a fact that the chimney sweeping industry isn't licensed in the same way as gas or electrical work. Anyone can technically pick up a set of rods and call themselves a chimney sweep. So when you're booking someone to work on your flue — the thing that vents carbon monoxide and keeps your house from burning down — it's worth understanding what the credentials on a company's website actually mean.
Here's what to look for, and what each qualification really tells you.
What Does HETAS Registration Mean?
HETAS stands for Heating Equipment Testing and Approval Scheme. It's the government-recognised body in England, Wales and Scotland for solid fuel heating — wood burners, multifuel stoves, open fires and the flue systems that serve them.
Being HETAS registered isn't just about passing a test once. It means the sweep is assessed against national competency standards, carries appropriate insurance, and keeps their knowledge current. When a HETAS-registered sweep visits your home and issues a certificate, that certificate is recognised by insurers and local authorities.
That last point matters more than most people realise. If you ever need to make a home insurance claim following a chimney fire or a carbon monoxide incident, your insurer may ask whether the chimney was swept and certified by a competent person. A receipt from an unregistered sweep may not be enough. A HETAS certificate is.
RJL Chimneys is HETAS registered. Every chimney sweep we carry out comes with a signed certificate — which you should keep somewhere safe, ideally with your home insurance documents.
What Does NVQ Qualified Mean for a Chimney Sweep?
An NVQ — National Vocational Qualification — is a work-based qualification assessed against real, practical competencies. It's not a classroom exam. It's evidence that someone has been assessed doing the actual job, to a recognised national standard.
For a chimney sweep, an NVQ means the sweep has been formally assessed on things like:
• Correctly identifying flue types, liner conditions and combustion appliances
• Safe working practices including preparation, sweeping and making good
• Identifying defects and explaining findings to homeowners
• Issuing certificates and completing records accurately
It takes time and commitment to achieve. Most people sweeping chimneys without an NVQ are operating on experience alone — which counts for something, but it isn't the same as formal, independently assessed competence. If something goes wrong and qualifications are questioned, an NVQ stands up.
Richard at RJL Chimneys holds an NVQ in chimney sweeping. It's one of the reasons RJL was built the way it was — on proper foundations, not shortcuts.
Trading Standards Approved — and Why That's Rarer Than It Sounds
The Trading Standards approval scheme is one that many people haven't heard of, but it carries real weight. Trading Standards is the local authority body that enforces consumer protection law — it investigates rogue traders, illegal practices and businesses that mislead customers.
Being approved by Trading Standards means RJL Chimneys has been independently vetted. The vetting covers things like:
• Verified qualifications and credentials
• Valid insurance documentation
• Customer feedback and complaint handling
• Compliance with relevant trading standards and consumer law
It's a rigorous process. Not every chimney sweep who applies gets approved. And crucially, it's reviewed — it's not a badge you buy once and keep forever. RJL Chimneys carries Trading Standards approval, which means you can book with confidence knowing someone independent has already done due diligence on the business.
What About Insurance?
RJL Chimneys carries £5 million public liability insurance. That covers damage to your property and injury to people as a result of our work.
Some sweeps operate without adequate cover, or with only basic insurance that may not cover specialist work like flue liner inspections or stove servicing. If something goes wrong and the sweep isn't properly insured, the cost falls on you. It's an uncomfortable truth but a real one.
£5 million isn't an arbitrary number — it's a level that genuinely protects you for most residential scenarios, including if work had to be redone or a structural issue was missed.
Questions Worth Asking Before You Book Any Chimney Sweep
Whether you book RJL Chimneys or someone else, these are worth asking:
• Are you HETAS registered? Can I see your registration number?
• Do you hold an NVQ in chimney engineering?
• Are you Trading Standards approved?
• What level of public liability insurance do you carry?
• Will I receive a signed certificate after the sweep?
Any reputable sweep should be able to answer all of those without hesitation. If you get vague answers or pressure to just 'get it booked in', that's worth paying attention to.
A Final Note on Why This Stuff Matters
Richard started RJL Chimneys in 2020 after years in the corporate sector — and one thing he brought with him was an instinct for doing things properly. Every qualification, every accreditation, every renewal is there for a reason: because the families in Northamptonshire, Bedfordshire, Buckinghamshire and Milton Keynes who invite RJL Chimneys into their homes deserve to know the person working on their fireplace actually knows what they're doing.
Carbon monoxide is invisible. Chimney fires can start in walls you can't see. These aren't scare stories — they're the reason the industry has standards in the first place. Choosing a properly qualified sweep isn't being overly cautious. It's just sensible.
