The contract terms that protect you on a cleaning job

The terms that pin down, in writing before the work starts, what you are getting and who is responsible: scope, standard, access, proof, insurance and price. Scope - exactly what will be cleaned: the whole system (canopy, filters, ductwork and fan), not just the visible parts. Standard - the standard the work will meet: cleaning to TR19 Grease. Access - how the ductwork will be reached, and who provides and pays for any added access panels. Proof/deliverables - what evidence you get: an internal-inspection report, before-and-after photographs of the ductwork, and a certificate. Insurance and competence - the contractor's public liability insurance and relevant accreditation/competence. Price and extras - a clear price, what it includes and excludes, and how any extras are quoted and agreed. Getting these agreed in writing protects you from a partial job, disputes, surprise extras, and having no comeback if something goes wrong - turning a vague booking into a clear, enforceable agreement. So the protective terms are scope, standard, access, proof, insurance and price, in writing. This is general commentary, not legal advice.

Because a vague verbal booking relies on assumptions and leaves you exposed - to a partial job, disputes, extras, and no comeback. If you book on a loose agreement ('clean the extraction, here's the price') without pinning down the details, you rely on assumptions that can leave you short: you might assume the whole system will be cleaned but get only the canopy (the common partial-job problem); you might assume a standard, proof or price that were never agreed; and if the work is inadequate or there is a dispute or problem, you have little to fall back on (no clear agreement about what was promised). So a verbal agreement exposes you to getting less than expected, disputes with nothing in writing to settle them, unexpected extras, and no comeback if it goes wrong. Clear written terms fix this by pinning down exactly what you are getting and who is responsible - so there is no ambiguity, no assumption, and a clear basis if anything goes wrong. So a verbal agreement is not enough because it leaves you relying on assumptions with no protection; written terms protect you. So get it in writing, not just verbal. This is general commentary, not legal advice.

Because pinning down the scope (the whole system) protects you from the commonest problem - a partial job that leaves the ductwork uncleaned. For an extraction clean, the scope should be the whole system: the canopy, filters, ductwork throughout, and fan. Stating this in the contract protects you from the partial-job problem (getting only the canopy cleaned, the ductwork left grease-laden) - because if the agreed scope is the whole system, a canopy-only job is a breach of the agreement, not just a disappointment you have no recourse for. Without the scope pinned down, a contractor might do only the visible parts (cheaper for them) and you would have little basis to object (you did not specify the whole system). So the scope term ensures you get the whole system, in writing, with the contractor committed to it - protecting you from the ductwork being left undone. This is one of the most important protective terms, given that the partial-job/canopy-only problem is exactly what leaves kitchens with a hidden fire risk and compliance gap. So the scope should be in the contract to guarantee the whole system is cleaned. This is general commentary, not legal advice.

An internal-inspection report, before-and-after photographs of the ductwork, and a certificate (to TR19 Grease) - the evidence that the whole system was genuinely cleaned. Because extract ductwork is hidden, its cleaning is otherwise unverifiable - so the contract should specify the proof you will receive: a report documenting what was inspected and cleaned and the condition found; before-and-after photographs of the ductwork internals (visual proof the hidden ductwork was reached and cleaned); and a certificate certifying the clean to the TR19 Grease standard. Requiring these as deliverables ensures you get the proof that the whole system (including the hidden ductwork) was genuinely cleaned - which you need for verification, your fire risk assessment, and insurance. Without the proof specified, a contractor might do the work but not provide the evidence (leaving you unable to demonstrate it) - or the lack of proof might hide that the ductwork was not actually done. So the contract should require the report, before-and-after photographs, and certificate as proof. So require internal-inspection report, before-and-after photographs, and a certificate. This is general commentary, not legal advice.

Yes - confirm the contractor's public liability insurance (and their competence/accreditation) before the work, so you are covered if something goes wrong and assured they can do the job properly. Public liability insurance covers damage or injury the work might cause (to your premises, or a person) - so confirming the contractor has adequate cover protects you if something goes wrong during the job. And confirming their competence and accreditation (that they are competent to clean to the standard - relevant accreditation, experience) assures you they can do the job properly, not just cheaply. So checking insurance and competence protects you against the risks of the work (damage, accidents - covered by their insurance) and against an incompetent contractor (who might do a poor or unsafe job). This is part of vetting a contractor before engaging them, and worth confirming (seeing evidence of the insurance and accreditation) rather than assuming. So yes - check the contractor's public liability insurance and competence before the work, as part of protecting yourself. So confirm their insurance and competence. This is general commentary; see checking a contractor's insurance and accreditation.

Yes - willingness to put clear terms in writing is a sign of a good, honest contractor, while reluctance to pin them down is a warning sign. A competent, honest contractor doing the whole job to standard, with proper insurance and a clear price, has nothing to hide and every reason to confirm it in writing - so a good contractor will be happy to agree clear terms (scope, standard, access, proof, insurance, price). Reluctance to pin these down, by contrast, is a warning sign: it may indicate they do not intend to do the whole job (avoiding a scope commitment), cannot meet the standard or provide the proof, lack proper insurance, or want to keep the price vague for later extras. So the willingness to agree clear written terms is itself a useful test of a contractor's trustworthiness - a good one welcomes it, a dubious one avoids it. So insisting on clear terms both protects you on the job and helps you identify a trustworthy contractor. So yes - a contractor's willingness to agree clear terms is a good sign (and reluctance a warning). This is general commentary.
