Every rodent control business rests on a small set of chemistry, and that chemistry is under review. It is easy to read that as a threat. Read carefully, it is closer to the opposite: a barrier that keeps rising is a barrier around the business you already run.
What Is Actually Under Review
The Health and Safety Executive ran a public consultation, which closed on 30 September 2025, on renewing the authorisations for the anticoagulant active substances the sector depends on: difenacoum, bromadiolone, brodifacoum, flocoumafen, difethialone and coumatetralyl. The review assesses whether suitable and sufficient alternatives exist, and its outcome is expected to shape rodenticide availability from 2026 onward.
I am not going to tell you how it lands, because nobody credible knows yet, and predicting it would be a disservice. What is safe to say is the trend. Second-generation anticoagulant rodenticides are already restricted to use in and around buildings, with outdoor use not permitted unless connected to a structure. Sale of these products for use in open areas and waste dumps ceased on 4 July 2024, and permitted use ended on 31 December 2024. Access has been getting narrower for two years, and this review is the next tightening, not a reprieve.
Why a Barrier Is Good News for an Owner
Here is the part that matters when you are thinking about a sale. A buyer does not just purchase your contracts; they purchase the difficulty of replacing you. If anyone could set up in your patch next quarter and match your service, your business would be worth a good deal less. Rising regulation is precisely what stops that happening.
The chemistry is harder to access than it was, and it now sits behind competence that is harder to prove. Since 1 January 2026, buying professional-use rodenticides requires proof of competence at the point of sale, and farm assurance no longer counts. Put those together and a compliant, certified, well-run operator is genuinely scarce. Scarcity is what a buyer pays a premium for.
The barrier you find irritating on a Monday morning is the same barrier that protects the business a buyer would be paying for.
None of this is about the specific molecules. It is about the position they put you in. The environmental pressure behind the whole direction of travel is real: CRRU's own stewardship monitoring, cited by its chairman Dr Alan Buckle, still finds that around 80 per cent of barn owls carry residues of one or more second-generation anticoagulants, and the stewardship regime has not met its environmental targets. That is why the rules tighten rather than loosen, and it is why the trend is unlikely to reverse.
What to Do About It Before You Sell
The risk in all of this is not the regulation itself. It is a business whose compliance is invisible or fragile. The work to fix that is modest and worth doing whether you sell this year or in three.
- Keep every technician's certification current, with award dates and CPD scheme membership recorded in one place
- Make sure compliance does not rest on a single person who could leave with you
- Document how your service delivers results without depending on any one product or method
- Keep evidence of your approach to stewardship, so a buyer can see you are on the right side of the trend, not exposed to it
