How to Price Rendering in the UK
Rendering is one of the more technical exterior trades — and one where poor pricing destroys margin fast. Whether you're quoting sand and cement, monocouche, silicone or a full EWI system, this guide covers how to measure, price and profit from every job.
The render market in the UK
Demand for rendering is steady and growing. Domestic renovation drives most of the residential work, but EWI (External Wall Insulation) grants — particularly under the ECO4 scheme — have opened up a significant social housing pipeline. New build specification work is also strong in regions where silicone and monocouche finishes are replacing traditional sand and cement as the default external finish. The shift away from painted pebbledash and textured coatings towards clean monocouche and silicone renders means customers are increasingly willing to pay premium prices for a quality finish — but only if you can demonstrate the difference.
Types of render and material costs
Sand and cement is the cheapest system to specify — materials run £8–12/m² — but it requires a skilled finisher and is slower to apply. Monocouche systems (K-Rend, Weber One Coat, Parex) cost £18–28/m² in materials but are faster to apply and self-coloured, which eliminates the painting cost. Silicone thin coat renders run £20–30/m² in materials and deliver a premium, self-cleaning finish that justifies higher customer-facing prices. EWI board plus render system costs £60–120/m² in total materials depending on board thickness, mesh spec and top coat choice — always get a materials schedule from your distributor before quoting.
How to measure and price render jobs
Measure wall area in m² and deduct openings. The standard rule is to deduct 50% of each opening area (doors, windows) — this accounts for the reveal work that replaces the flat area saving. Charge per m² inclusive of both materials and labour; never give a day rate to customers for render work. Experienced renderers working on monocouche should achieve 15–25m² per day depending on the substrate, access and weather. Sand and cement scratch coat plus float and set runs slower — budget 10–18m² per man per day. Price your per-m² rate to reflect the system: silicone thin coat over existing render is faster than a full sand and cement base coat build-up, and your price should reflect that.
Prep, primer and access costs
Prep and access are where renderers lose money. Dubbing out hollow areas, hacking off existing render, or patching cracks should be priced separately at £30–60/m² — never bundle it into your per-m² rate and hope for the best. Primer adds £3–6/m² and should always appear as a separate line item on your quote. Scaffold for a standard residential job runs £400–900 depending on height and length; always get a scaffold quote before finalising your tender and pass the full cost through on the quote. MEWP (cherry picker) hire runs £200–400/day and is often a better option for smaller areas or awkward elevations. Itemising these costs separately protects your render rate from being squeezed and makes the quote easier for the customer to understand.
EWI systems pricing
Full EWI installed — insulation board, mesh reinforcement, base coat and top coat — runs £120–180/m² for supply and fit. PAS2030 certification is required if you want to work on ECO scheme-funded projects, and it opens up significant social housing and retrofit contract pipelines. Measure EWI carefully: adding 100mm of board to an elevation changes reveal depths, window sill projections and soffit details, all of which require additional materials and time. Always specify window sill extensions, reveal infills and expanded reveals as separate line items — these small details add up to meaningful money on a full-house EWI job and are easy to miss in a per-m² headline rate.
Running a render business profitably
Target 40–50% gross margin across labour and materials combined. The biggest margin killers are underquoting prep work, not charging for access, and quoting per-day to customers who then expect more output than the job allows. Always quote per m² — it's cleaner, it's industry standard, and it protects you when productivity is affected by weather or a difficult substrate. Trade2Base's AI quoting tools help renderers calculate m² areas quickly, add access cost line items automatically, and track margin per job so you know exactly where you're making money.
