How a renovation quote is structured

A good quote answers three questions without you having to ask: exactly what will be done, how it's measured and billed, and what's explicitly excluded. If any of these are missing, it's worth asking before you commit rather than being surprised mid-project.

That means a clear breakdown into separate line items — preparation, materials, execution, disposal where relevant — rather than one lump figure with no detail. The more detailed the line items, the easier it is to compare one quote against another, and the clearer it is what you're actually paying for.

Different units apply depending on the type of work, and the unit chosen has a direct effect on how precisely a line item can be calculated. Wall surfaces are usually measured in square metres (m²), edges and trims like skirting boards in running metres, individual elements such as doors or radiators in pieces, and work with unclear or variable scope — for example repairing unknown damage — in hours.

For clearly defined, easily assessed work, a lump-sum price is often agreed: a fixed amount for the whole job, regardless of the actual hours spent. This gives you budget certainty, but it depends on the walls having been realistically assessed at the site visit. What matters is that the unit fits the type of work: a lump sum for a wall with an unknown surface condition is riskier than billing based on actual effort.

Covering, masking, small repairs and priming should appear as their own line item in the quote, not be silently bundled into the painting cost. That way you can see how much of the cost is actually the visible finishing work and how much is the preparation that determines its quality.

A separate preparation line item also makes it clear what happens if extra work is needed — for example if masking reveals that far more repair work is required than was originally visible.

The quote should state which material will be used — for example dispersion, silicate or latex paint, or the type of skimming compound for plastering work — and whether the number of coats is specified. Two top coats are often necessary with a colour change or on an absorbent surface; if only one coat is priced in, the result can end up uneven.

If you want a specific colour or brand, that should also be part of the quote, since it can affect material cost and sourcing.

How accessible the site is directly affects the workload, even though it has nothing to do with the actual wall area. Which floor, whether there's a lift, the distance from parking to the flat, and whether the flat stays occupied or is empty all affect transport time and workflow.

Work outside normal hours — for example evenings or weekends so a business can keep running — should also be reflected in the quote where it applies. A quote that doesn't account for these conditions, because they weren't mentioned at the site visit, often needs to be revised later.

A realistic schedule with a start and end date, and stages for larger projects, is part of a complete quote. For multi-day or multi-week jobs, it's common for payments to be staged: a deposit on confirmation of the order, sometimes a partial payment tied to a defined stage of progress, and a final payment after joint sign-off.

What happens if extra work comes up during execution — for example if unexpected damage appears behind old wallpaper — should also be addressed. Good practice means discussing the extra work before it's carried out, ideally in writing, rather than having it appear for the first time on the final invoice.
