What Every Professional Trade Quotation in the UK Must Include

A well-constructed quotation does more than state a price. It defines the scope of work, establishes the legal basis of the contract, protects the contractor against scope creep and unrealistic client expectations, and demonstrates the professionalism that differentiates a credible business from a handwritten note pushed through the letterbox. In the UK, several legal requirements govern what must appear on business documents, and omitting them can undermine the enforceability of the quote as a contract and raise questions with HMRC.

Your Business Identity and Contact Details

Every quotation must clearly identify the business issuing it. For sole traders, this means your full name (or the name under which you are registered with HMRC), your trading name if you use one, your business address, and contact details including telephone and email. For limited companies, the requirements are more specific and are set out in the Companies Act 2006: you must show the full registered company name exactly as it appears at Companies House, your company registration number, the jurisdiction of registration (England and Wales, or Scotland, or Northern Ireland), and the registered office address — which may be different from your trading address. Failing to include the registered name and number on business documents is a criminal offence under the Companies Act, though in practice enforcement is primarily through civil liability rather than prosecution. The registered office address must be in the same country as the company's jurisdiction and cannot simply be a PO Box without a physical address.

VAT Registration Details

If your business is registered for VAT, every quotation and invoice you issue for taxable supplies must include your VAT registration number in the format GB followed by nine digits. This requirement applies even if you are issuing a quote rather than an invoice, since clients who are VAT registered will want to verify your VAT number before entering into a contract with you. Your quote should also indicate the applicable VAT rate for the work being quoted — standard (20 per cent), reduced (5 per cent), or zero — and show the net amount, VAT amount, and gross amount separately. For construction work where the Domestic Reverse Charge applies, the quote should indicate that VAT will be accounted for under DRC by the customer, so the client understands that no VAT will appear on your invoice. Including VAT information accurately at the quotation stage prevents disputes later when the invoice arrives and the client questions why the amount differs from their expectation.

CIS Registration Reference

For contractors working under the Construction Industry Scheme, including your UTR (Unique Taxpayer Reference) on quotations and invoices for construction services is important for the smooth operation of CIS between you and your clients. Main contractors need your UTR to verify you with HMRC before making their first payment and to correctly identify you in their monthly CIS returns. Although there is no absolute legal requirement to display your UTR on a quotation (as opposed to an invoice or deduction statement), including it demonstrates that you are properly registered under CIS and reduces the administrative friction for your client. For subcontractors with gross payment status, noting "Gross Payment Status" on your quotation signals that the client does not need to deduct CIS from your payment, which is useful information at the contracting stage.

Scope of Work and Inclusions/Exclusions

The body of the quotation should describe the scope of work clearly enough that a reasonable person reading it would understand exactly what is included and, ideally, what is explicitly excluded. Vague descriptions such as "bathroom renovation" invite disputes about whether replastering the walls, supplying tiles, or disposing of waste were part of the contract. Specific descriptions — "supply and fit one thermostatic shower enclosure model XYZ, including connection to existing hot and cold supplies and installation of new waste to existing soil stack; excludes floor tiles and plastering" — leave far less room for misunderstanding. Including explicit exclusions is as important as defining inclusions, since clients often assume that everything connected to the job is within scope unless told otherwise. Variation procedures — what happens if the scope changes and how the additional cost will be calculated and agreed — should also be addressed in the quotation or accompanying terms.

Quote Validity Period

Every quotation should state a validity period — typically twenty-eight or thirty days — after which the quoted price may be revised. This protects the contractor against accepting a job months after quoting at prices that no longer reflect material costs or labour rates. Without a stated validity period, a quotation could potentially be accepted at any time, and courts have generally held that an offer without a stated duration remains open for a reasonable time, which is subjective and unpredictable. The validity period should be stated clearly: "This quotation is valid for 30 days from the date above." For work where material costs are particularly volatile — copper for plumbing, steel for structural work — a shorter validity period or a materials price fluctuation clause may be appropriate.

Payment Terms and Conditions

Payment terms should be stated on every quotation, not just on the invoice. Clients who accept a quote without seeing the payment terms and then object to them when the invoice arrives create unnecessary disputes. Standard terms for UK trade contractors typically include a deposit requirement (commonly 10 to 30 per cent for smaller jobs, or a structured milestone schedule for larger ones), the payment method accepted (BACS, card, cash), the due date for payment after invoice (commonly fourteen or thirty days), and a statement that statutory interest will accrue on overdue amounts under the Late Payment of Commercial Debts Act 1998. For limited company clients, it is worth checking Companies House records before accepting a large contract to verify that the client company is in good standing and not in administration or subject to a winding-up petition.
