Service quality complaints: documenting the agreement

A service-quality complaint should compare what was promised with how the service was performed. A disappointing outcome does not necessarily establish a lack of reasonable care and skill; an express promise of a result may require separate assessment. ^[1]

Identify the agreed scope

Collect the booking, proposal, specification and statements relied on before purchase. Distinguish advice, an attempted repair and a guaranteed deliverable. Record any customer instructions or missing information that affected performance.

Describe concrete shortcomings rather than relying on a rating or general dissatisfaction. For example, identify omitted tasks, incorrect measurements or a missed contractual milestone.

Request a remedy tied to the failure

Explain whether repeat performance would resolve the problem and whether it remains practical. Keep evidence of extra expenditure claimed as a consequence. Do not add unrelated losses simply to strengthen the complaint's negotiating position.

Salesperson promises may help establish the agreement. Professional service complaints can involve a separate regulator or ombudsman route. Ask the provider to answer the defined points and retain its response, including any proposed correction that would require further payment or acceptance of new terms.

Describe the service the provider undertook Start with the task the provider agreed to perform and the purpose communicated when booking. A diagnostic appointment, an attempted repair and a promise to deliver a finished result are different commitments. Preserve the wording used in the proposal or conversation. If the provider explained that an outcome could not be guaranteed, retain that qualification alongside any more definite promise. The complaint should address the service actually commissioned rather than a result the customer hoped for but never discussed with the trader.

Identify the agreed inputs and responsibilities. A provider may need measurements, access, documents or instructions from the customer before the task can be completed. Record what was supplied and when, including any warning that information was incomplete. If the trader proceeded despite an identified gap, preserve that decision too. This gives an adviser a balanced account of performance and avoids attributing every shortcoming to one side before the effect of the customer's instructions or the provider's professional judgement has been examined.

Compare actions with a concrete service standard Describe the observed failure in a form that can be investigated. For a cleaning service, identify the agreed areas left untreated; for a measurement service, compare the recorded dimensions with a reliable check; for document preparation, identify the omitted agreed item. A poor online rating or general complaint about attitude may reveal dissatisfaction without establishing deficient performance. Where the service involves professional judgement, distinguish a result that was disappointing from an identifiable failure in the process or standard of work required.

Business Companion's services guidance distinguishes reasonable care and skill from an automatic guarantee of a desired outcome. It also addresses information about the service that the consumer took into account and the role of agreed price and timing. Use those distinctions to identify what the trader is asked to answer. If the complaint depends on a specific assurance, show when it was made and how it affected the booking or a later service decision. Preserve the actual wording instead of upgrading a tentative estimate into an unconditional promise. ^[1]

Consider whether the service can still be corrected Explain what satisfactory repeat performance would involve and whether it remains practically possible. A task with a continuing purpose may be capable of correction, while work tied to a past event can raise a different question. Identify the remaining usefulness of the service and the inconvenience of repeating it. Ask the provider to explain its proposed correction, including timing and any requested payment. A meaningful proposal should address the alleged failure rather than simply offer the same incomplete service again under a new booking reference.

The statutory service remedies can include repeat performance or a price reduction in the circumstances described by the guidance. A price reduction is not automatically the full amount paid, and other claimed losses need their own basis and evidence. Keep a calculation separating the service price from additional expenditure said to result from the failure. If another provider is consulted, ask for an itemised explanation of the work required. This helps distinguish correction of the original task from an expanded service the customer has decided to buy afterwards. ^[1]

Request an answer to each disputed point Write the complaint around a small number of identifiable issues, each linked to the agreement and evidence. State the result sought and explain why it would address the problem. If the provider says the work met the required standard, ask it to identify the relevant records or method. Where an independent view may assist, consider the precise question and proportionate cost. Avoid asking an assessor merely to confirm dissatisfaction; their contribution should help resolve the actual disagreement about scope, performance or the proposed remedy.

Retain the provider's response and assess any offer in full, including conditions that settle other issues or require new charges. Record what has been corrected and what remains unresolved. If escalation becomes necessary, identify the appropriate complaint or dispute route for that service and provide the focused evidence pack. Keep any regulatory concern distinct from a request for a personal refund or compensation. A useful complaint explains the contracted task, the demonstrated shortcoming and the remedy sought without assuming that every disappointing experience has the same legal answer.
