What to Include in a Belgian Renovation Quote

A useful renovation quote lets the customer understand what will be delivered, how the price is built and which decisions can still change it. It also gives the site team a workable starting point after acceptance. Avoid vague bundles such as “complete bathroom” when materials, quantities, preparation or finishing can be described separately.

Identify both parties and the project

Use the contractor's legal name, address, enterprise and VAT details, plus reliable contact information. Identify the customer and the exact work location; the billing address may be different. Give the quote a unique reference, issue date and validity period so that everyone knows which version is being discussed.

Briefly describe the existing situation and the requested outcome. A drawing, measurement sheet or photo set can be attached and referenced by date. This prevents a later attachment from silently changing the scope.

Divide the work into understandable sections

Structure the quote in the same order that the project will be prepared and executed. Depending on the renovation, sections might cover protection, demolition, disposal, structural preparation, technical installations, finishes and handover. For each relevant line, state:

• what is supplied and installed;
• the quantity, unit and unit price where appropriate;
• the chosen material or a clearly defined allowance;
• preparation and finishing included in the price;
• work explicitly excluded or assigned to another party.

The aim is not to create the longest document. It is to make boundaries visible where customers and contractors could reasonably understand the same phrase differently.

Explain price, VAT and payment stages

Show the subtotal, the VAT treatment used and the total. Do not select a reduced VAT rate merely because the project is a renovation; verify the current conditions and evidence for the actual building, customer and work. The FPS Finance VAT guidance is the primary starting point, while an accountant should review an unusual case.

Link payment stages to observable milestones, such as ordering a defined material package or completing a named phase. State payment terms, the process for an advance invoice and what happens when customer decisions delay the next stage.

Record assumptions and customer choices

Renovation work often contains unknowns behind walls, floors or ceilings. List the assumptions used to price the work and describe how concealed conditions will be handled. If a fixture or finish has not been chosen, state the allowance and the deadline for the decision. Record who measures, who requests permits and who coordinates third parties.

Avoid promising a fixed completion date when essential choices or access dates are still open. A proposed start window and estimated duration can be clearer, with the dependencies written beside them.

Define changes before work begins

The quote should explain that additional or changed work is described and priced before execution, except where an immediate safety measure is necessary. Use a written change reference connected to the original quote. It should show the requested change, price effect, planning effect and customer approval.

This process protects both sides: the customer sees the consequence before deciding, and the contractor does not have to reconstruct verbal instructions at final invoicing.

Make acceptance unambiguous

Provide a clear acceptance method with the quote reference, version, total and date. Keep the accepted document and attachments together. After acceptance, create the project from that approved scope rather than from memory or a sales note.

Belgian economic authorities provide additional guidance on transparency in renovation and shell-construction contracts. Use the current FPS Economy renovation guidelines as a review source and obtain professional advice for contract clauses specific to the project.
