Kitchen deep cleaning - specification
Ask three providers to quote a deep clean without telling them exactly what you want, and you get three different jobs and three incomparable prices. A written specification fixes that - it defines the job so everyone quotes the same thing, and so you actually get what you asked for.
The short answer
A deep clean specification is a written document that defines exactly what you want done: the scope (which areas and equipment), the standard (how thorough, to what benchmark), the frequency (if it is a recurring arrangement), and the evidence required (the reports and certificates). Writing it turns a vague request into a clear, comparable job - so providers quote the same thing on the same basis, and so you have a defined standard to hold the work to. A spec protects you both at quoting and at delivery.
Why a spec matters
The problem a specification solves is vagueness. If you ask for a deep clean without defining it, each provider interprets it their own way - different scope, different thoroughness, different inclusions - and quotes accordingly. The prices come back incomparable, because they are for different jobs, and whatever you accept, you have no defined standard to hold the work to. A vague ask produces a vague result, and disputes about what should have been included tend to follow.
A written specification removes that vagueness by defining the job precisely. It states what you want done, to what standard, so every provider quotes against the same defined scope - making the quotes genuinely comparable - and so the work has a clear benchmark it must meet. It converts a deep clean from an ill-defined service into a specified job with agreed parameters. For anything beyond the simplest one-off, and especially for a recurring arrangement or a multi-site operation, that clarity is worth the effort of writing it down.
Scope and standard
The core of a specification is scope and standard. Scope defines what is to be cleaned - which areas, which equipment, which parts of the system. A good scope is specific: the kitchen areas covered, the equipment items included (and their interiors), the extract system, the refrigeration, the high surfaces, the drains, the hard-to-reach areas. Listing what is in - and, where useful, what is out - leaves no ambiguity about what the job covers, which is exactly what stops the gaps and disputes that vagueness causes.
Standard defines how thoroughly, and to what benchmark. It states the level the clean must achieve - a genuine take-it-back-to-clean reset rather than a light pass - and, where a recognised standard applies, references it: the extract system cleaned to the TR19 Grease standard, for instance, with its defined verification. Specifying the standard means the provider knows what quality is required and you have a benchmark to check the work against. Together, scope and standard say what is done and how well - the two things a vague ask leaves dangerously undefined.
Frequency and evidence
For anything more than a one-off, the specification should define frequency - how often the deep cleaning is to happen. This is where the spec ties into a maintenance schedule: stating the intervals, matched to how the site is used, turns the deep cleaning into a defined, recurring arrangement rather than an occasional call-out. For an extract system, the frequency should reflect the cooking volume and the recognised guidance; for the kitchen generally, it should match the usage. Specifying it makes the recurring commitment clear on both sides.
Evidence is the other essential element, and easy to forget. The spec should state what documentation you require at the end - the reports and certificates, with the detail they must contain, that give you the proof of the clean insurers, fire risk assessors and inspectors need. Specifying the evidence up front ensures you get a proper certificate and report, not a token one, and makes the documentation part of the defined deliverable. A spec that defines scope, standard, frequency and evidence covers what is done, how well, how often, and what you get to prove it.
How to use it
A specification earns its keep at two points. At quoting, you give the same spec to every provider, so they all quote against the identical defined job - which makes the quotes genuinely comparable and stops the cheaper-because-smaller problem, since the scope and standard are fixed. You are comparing price for a defined job, not guessing what each quote includes. That alone is a strong reason to write one before seeking quotes for anything significant.
At delivery, the spec is the benchmark you hold the work to. Because the job was defined - scope, standard, evidence - you can check that what was delivered matches what was specified, and you have a clear basis if it does not. The spec turns delivery from a matter of hoping the provider did a good job into checking the work against an agreed standard. So the specification protects you across the whole process: it makes quotes comparable, it defines the deliverable, and it gives you the benchmark to ensure you actually get what you paid for.
The takeaway
A deep clean specification is a written document defining exactly what you want: the scope (which areas and equipment), the standard (how thorough, to what benchmark), the frequency (for a recurring arrangement), and the evidence required (the reports and certificates). It turns a vague ask - which produces incomparable quotes and an undefined result - into a clear, specified job that everyone quotes on the same basis and that has a benchmark to be held to.
Writing one is worth the effort for anything beyond the simplest one-off, and especially for recurring or multi-site arrangements, because it protects you at both quoting and delivery: comparable quotes for a defined job, and a clear standard to check the work against. Define the job in a specification, and you get the job you defined - rather than whatever each provider chose to interpret from a vague request. The spec is how you take control of what a deep clean actually delivers.

Because a vague ask produces incomparable quotes and an undefined result. A spec defines the job precisely, so providers quote the same thing on the same basis and the work has a clear benchmark to be held to - protecting you at both quoting and delivery.
What is to be cleaned - specifically: the kitchen areas covered, the equipment items and their interiors, the extract system, refrigeration, high surfaces, drains and hard-to-reach areas. Listing what is in, and where useful what is out, leaves no ambiguity about the job.
State the level the clean must achieve - a genuine take-it-back-to-clean reset - and where a recognised standard applies, reference it, such as the extract system cleaned to TR19 Grease with its verification. This gives the provider a required quality and you a benchmark to check.
So you get a proper certificate and report, not a token one. Specifying the documentation you require up front - and the detail it must contain - makes the proof of the clean part of the defined deliverable, which insurers, fire risk assessors and inspectors need.
You give the same spec to every provider, so they all quote against the identical defined job - making the quotes genuinely comparable and stopping the cheaper-because-smaller problem, since the scope and standard are fixed. You compare price for a defined job, not a guess.
We quote and deliver against a clear deep clean specification - scope, standard, frequency and evidence defined - so you get exactly the job you specified, with the proof to show it.
