How to Quote a Rendering Job: UK Pricing Guide

Rendering is a skilled, material-heavy trade where the quote can make or break the job. The surface you see is only part of it: the substrate, the preparation, the render system and, above all, the scaffold all drive the cost, and a quote that misses any of them eats your margin fast. This guide walks through how to quote a rendering job in the UK properly, so you price the whole job and win it at a figure that actually pays.

It is written for UK rendering contractors who want to quote accurately and protect their profit.

Step 1: Survey the Substrate and the Building

Rendering quotes depend heavily on what you are rendering onto and how you reach it, so a proper survey is essential.

• Substrate. Brick, block, existing render or insulation each behave differently and suit different render systems.
• Condition. Cracks, blown areas, damp or a failing old render all mean repair or removal before you start.
• Access and height. Anything above ground floor needs scaffold, which is one of the biggest costs on the job.
• Area and detail. Windows, doors, features and awkward junctions all add cutting, beading and time.

Step 2: Measure the Area

Measure the wall area in square metres, deducting large openings such as windows and doors, and note the running length for beads and stop ends. On a whole house, work elevation by elevation so nothing is missed, and add an allowance for waste and for the extra material a textured or thicker system uses.

Step 3: Choose the Render System and Understand the Cost Drivers

• Traditional sand and cement is cheaper in material but labour-intensive and usually painted afterwards.
• Monocouche is a through-coloured one-coat system that is quicker to finish but dearer in material.
• Thin-coat and silicone systems need a base and mesh and skilled application, and are priced accordingly.
• Number of coats, texture and colour all change the time and material.

Step 4: Price the Preparation

Preparation is where thin render quotes lose money. Price hacking off and removing failed render, repairing the substrate, fitting beads, angle stops and mesh where needed, and any primer or basecoat. On a re-render, the removal and making good can be as big a job as the rendering itself, so cost it as a distinct, honest line rather than absorbing it.

Step 5: Scaffold Is a Major Cost

For anything above working height, scaffold or a tower is essential and a real, significant cost. Decide and state clearly whether you are supplying it or the client is, and price the hire period realistically, because render needs time to be applied and to cure. Underestimating scaffold is one of the fastest ways to turn a profitable render job into a loss.

Step 6: Set Your Labour Rate

Rendering labour is usually priced per square metre or on a gang day rate, and it varies with the system, the number of coats and the amount of detail. Traditional render and heavily detailed elevations take longer than a plain monocouche wall. Difficult access, prep and weather all affect it too. Treat any published figure as a starting point: the system, the substrate and your local market set the real price, and figures exclude VAT.

Step 7: Price the Materials with a Markup

• Render in the chosen system, plus wastage.
• Beads, mesh, angle stops and stop ends.
• Primer or basecoat where the system needs it.
• Sand and cement for a traditional render.
• Consumables and any protection and clean-up.

Add a sensible markup for sourcing, collection and handling, and be clear about who supplies what.

Sample Quote Breakdown: Rendering a Rear Elevation

• Scaffold hire for the elevation: fixed price, or excluded and noted if by others
• Hack off and remove failed render, make good: labour and disposal
• Apply chosen render system to the measured area, including beads: labour and materials with wastage
• Total, with VAT shown separately if you are registered

Common Rendering Quoting Mistakes

• Underestimating or forgetting the scaffold cost.
• Absorbing the removal of old render and making good.
• Choosing a render system that does not suit the substrate.
• Leaving out beads, mesh and primer from the materials figure.
• Quoting a single price with no breakdown, so the client only compares on number.

Present a Quote That Wins the Job

Rendering is a big, visible spend for a homeowner, and they compare quotes carefully. A clear, itemised proposal showing scaffold, preparation, the render system and terms tells the customer you understand the whole job and reassures them the price is fair. That clarity often wins the work over a cheaper, vaguer quote.
