What to look for
- NEA Vector Operator Licence. Professional pest control should be carried out by an NEA licensed company. Ask for the registration number.
- Certifications. BCA and bizSAFE certification show the company meets construction and workplace-safety standards, which matters for commercial and larger jobs.
- Source treatment, not cover-up. Mould returns when the moisture behind it is ignored; pests return when the harbourage and food source remain. A good company treats the cause, not just the stain or the insect you can see.
- Written warranty. A warranty on eligible treatments shows the company stands behind its work. For bed bugs, look for unlimited re-treatment; for mould, a coverage period matched to the scope.
- Track record and reviews. A consistent rating across a meaningful number of Google reviews, plus any independent recognition such as media features.
- Transparent pricing. Clear, itemised pricing with no hidden charges.
- Safety. Family and pet safe methods, with low-chemical or heat-based options where suitable.
Mould removal: what a good company does differently
Mould is a moisture problem, not just a stain. The right company uses moisture meters and inspection to find the cause, removes the mould with proper biocide rather than painting over it, applies anti-mould protection where suitable, and backs eligible work with a warranty. Painting over mould without treating the moisture is the most common reason it returns.
Pest control: what a good company does differently
Effective pest control targets the whole life cycle and the harbourage, not just the pests you can see. For bed bugs, whole-room heat treatment combined with residual protection reaches eggs, nymphs and adults in one visit. For recurring commercial needs, look for scheduled service with monitoring and audit-ready documentation. NEA licensing and HACCP-safe options matter for F&B and sensitive sites.
