Rendering Costs UK — What to Charge for Sand & Cement, Silicone and K-Rend in 2026

The Main Render Types and What to Charge

Before you quote a price you need to settle on a system, because the material cost, the number of coats, the drying time and the skill required all change with it. Here are the render types you'll be asked about most often in the UK, with current per-m² rates.

Traditional Sand & Cement Render

Sand and cement is the original, lowest-cost system: a scratch coat and a top coat of cement, sand and lime or plasticiser, usually applied over blockwork or brick. It is durable, well understood and easy to source materials for, but it cracks if mixed or applied badly and it always needs painting — masonry paint is not optional, it's part of the spec. Most cracking call-backs in rendering come from sand and cement jobs where the mix was too strong or the wall moved.

Because the material is cheap, the price is mostly labour. Factor in the painting separately — two coats of breathable masonry paint adds time and material, and customers often forget it's a cost until you spell it out in the quote.

• Sand & cement render only: £40–£70/m²
• Masonry paint (two coats) on top: £8–£15/m² extra

Monocouche (Through-Colour) Render

Monocouche is a one-coat, through-colour render — the colour runs all the way through the material, so it never needs painting and chips don't show a different colour underneath. It's applied by hand or sprayed, ruled flat and then scraped back to a textured finish once it has gone off. Brands like Weber, Parex and K Rend all sell monocouche systems. It's a strong mid-range choice for new extensions and is popular because it's low maintenance.

The material is more expensive than sand and cement, and it's less forgiving — you have a narrow window to scrape it and the weather has to cooperate. But you save the painting stage entirely, which often makes the all-in cost competitive with a painted sand and cement job.

• Monocouche render (supply and apply): £50–£90/m²

Silicone / Thin-Coat Acrylic Render

Thin-coat systems are the premium modern finish. The wall is prepared with a basecoat that has fibreglass reinforcing mesh embedded in it, then a thin (2–3mm) silicone or acrylic topcoat is applied over a primer and trowelled or floated to a uniform grain. Silicone topcoats are breathable, water-repellent, self-cleaning to a degree and come in a huge colour range. This is what most customers picture when they want a "smooth modern render".

It's the most labour- and material-intensive of the standard systems because of the mesh basecoat, primer and topcoat stages — but it gives the best-looking, longest-lasting and lowest-maintenance result, so it commands the highest price. Silicone slightly outperforms acrylic on breathability and dirt resistance, which justifies pricing it at the top of the range.

• Silicone / thin-coat render on mesh basecoat: £55–£100/m²

K-Rend and Scraped Textured Finishes

K Rend is a brand name that has become shorthand for silicone-based, through-colour scraped-texture render. It's applied in two coats and scraped back to an even, slightly granular finish, and like monocouche it doesn't need painting. It's extremely popular in the UK for both new build and re-render work because the finish is robust and the colour is integral. Pricing sits between monocouche and a smooth silicone topcoat depending on the exact spec.

• K-Rend / scraped silicone texture: £55–£95/m²

Pebbledash and Roughcast

Pebbledash (dry dash) is a render coat onto which dry aggregate is thrown while wet; roughcast (wet dash) mixes the aggregate into the render before it's thrown on. Both are traditional, hard-wearing and good at hiding imperfect walls, which is why so much older UK housing stock has them. Demand today is split between matching repairs on existing dashed houses and customers wanting it removed and replaced with a smooth modern finish.

• Pebbledash / roughcast (supply and apply): £45–£75/m²

Lime Render

Lime render is the correct choice for older, solid-wall and listed buildings that need to breathe. Unlike cement, lime is vapour-permeable, so it lets damp move out of the wall rather than trapping it — using cement render on a period property is a classic cause of trapped damp and spalling. Lime work is slower, needs more coats, has to be protected from drying too fast and demands genuine skill, so it sits at the top of the price range. If you're set up for it, heritage and conservation-area work is well paid and far less price-shopped than standard render.

• Lime render (supply and apply): £70–£120/m²

Choosing a Render System

The right system depends on the wall and the customer's budget, not just on what you prefer to apply. A few rules of thumb that keep you out of trouble:

• Period or solid-wall property: specify lime. Cement on a breathable wall traps moisture and you'll get a damp call-back.
• Modern blockwork extension on a budget: sand and cement plus paint, or monocouche if they'd rather avoid repainting.
• Customer wants the modern smooth look and low maintenance: silicone thin-coat on a mesh basecoat is the right answer and the easiest to sell on a sample board.
• Re-render of a dashed or cracked house: K-Rend or silicone, but only after the substrate has been assessed and prepared properly.

Always make the spec explicit in writing. A customer who agreed to "render" without understanding which system can dispute the finish later. Showing a physical sample of the grain and colour at quote stage closes more jobs and prevents arguments at the end.

Preparation — Where Jobs Are Won or Lost

Render is only as good as what's under it. Prep is the part inexperienced quoters forget, and it's where margins evaporate when the job runs over. Build the following into every quote rather than discovering it on day one:

• Hacking off old render: removing failed sand and cement or pebbledash is dirty, slow work and generates a lot of waste. Allow for labour, skip hire and disposal. This alone can add £10–£25/m² to a re-render.
• Substrate assessment: the wall needs to be sound, clean and able to take the new render. Painted, friable or contaminated surfaces need treatment or a key coat first.
• Beads and stops: bell-cast beads, stop beads, corner beads and movement joints are essential for a clean, crack-free finish — never skip them to save a few pounds.
• Reinforcing mesh: thin-coat and EWI systems require fibreglass mesh bedded into the basecoat, and it's good practice over changes of substrate to prevent cracking.
• Background prep: dubbing out hollows, sealing penetrations and protecting windows, doors and the ground all take time that has to be priced.

Scaffolding — Often the Biggest Single Line

On anything above single storey you legally need safe access under the Working at Height Regulations 2005, and for rendering a whole house that almost always means full scaffolding rather than towers. Scaffolding is frequently the single biggest cost on a render job after labour, and underestimating it is the fastest way to turn a profitable quote into a loss.

• Scaffolding for a 2-storey terraced (one or two elevations): £600–£1,200
• Scaffolding for a 2-storey semi (wrapping the rendered elevations): £900–£1,800
• Scaffolding for a 2-storey detached (full wrap): £1,500–£3,500+

Always get a quote from your scaffold supplier before you price, or use a conservative known day rate. Quote scaffolding as a separate line so the customer sees it's a real third-party cost — that also stops you being undercut by anyone working off ladders who shouldn't be. Render also needs the scaffold up for longer than other trades because of drying and curing time, so confirm the hire period covers your full programme plus weather contingency.

EWI Render — The Premium Option

External wall insulation (EWI) bonds and mechanically fixes insulation boards (EPS, mineral wool or phenolic) to the wall, then renders over them with a meshed basecoat and a silicone or acrylic topcoat. It upgrades the thermal performance of solid-wall and poorly insulated homes while giving them a fresh rendered finish, so you're selling energy savings as well as looks. It's the highest-value rendering work most contractors will quote.

It's also the most technical: board fixing, careful detailing at reveals, sills and the DPC line, and getting the render system right over insulation all matter for both performance and warranty. Many EWI systems must be installed by approved applicators to keep the manufacturer guarantee valid.

• EWI with insulation and rendered finish: £100–£180/m²

Painting and Ongoing Maintenance

Through-colour systems — monocouche, K-Rend and silicone topcoats — are sold partly on the fact they never need repainting. Sand and cement always needs masonry paint, and that paint needs renewing every 8–12 years, which is a genuine lifetime cost worth raising with the customer when they're weighing systems. Silicone topcoats have a degree of self-cleaning and dirt resistance, but in shaded or north-facing spots even these can pick up algae over time and benefit from an occasional soft wash. Make the maintenance story part of your sales pitch — it justifies the higher upfront price of the through-colour and silicone systems.

What Affects the Quote

Two render jobs of the same square metreage can differ by thousands of pounds. The main drivers to check before you commit a price:

• Height and access: scaffolding cost, setup and the slower pace of working at height. The biggest swing on most quotes.
• Number of storeys and elevations: more wall and more scaffold. Confirm exactly which elevations are in scope.
• Surface condition: sound bare blockwork is cheap to render; hacking off failed render and repairing the substrate is not.
• Render type: sand and cement at one end, EWI and lime at the other — easily a 3–4x difference per m².
• Colour and finish: bespoke or dark colours and fine smooth finishes cost more in material and labour than a standard grain.
• Weather and drying: render can't be applied in frost, heavy rain or strong sun, so the season affects how long the scaffold stays up and how much weather risk you carry.

Materials and Labour Split

On a sand and cement job, material is a small fraction of the price and labour dominates. As you move up to monocouche, K-Rend and silicone, the material share rises because the systems are proprietary — beads, primer, mesh, basecoat and topcoat all add up — but labour still typically makes up the larger part. On EWI the insulation boards, adhesive and fixings push materials to a much bigger share of the total. A rough working split for a standard silicone or monocouche job is around 60–70% labour and 30–40% materials before scaffolding, which is quoted separately. Knowing your split per system lets you flex a price without going below cost.

How to Quote Profitably and Cover Weather Delays

Render is more exposed to the weather than almost any other trade, and weather delays are the main reason render jobs lose money — the scaffold sits idle, the crew is stood down, and a wash-out can ruin a part-finished elevation. Protect yourself:

• Quote scaffolding with a realistic hire period that includes weather contingency, not the best-case programme.
• State in your terms that the start date and duration are weather-dependent, and that render won't be applied in frost, heavy rain or extreme heat.
• Build a contingency margin into seasonal work — autumn and winter jobs carry far more risk than a settled summer week.
• Price prep and disposal as their own line items so the customer sees the value and you don't absorb hacking-off costs you didn't expect.
• Stage payments against milestones (scaffold up, basecoat complete, finish complete) so your cash flow isn't exposed if the job stretches across bad weather.

It also pays to know which jobs and which marketing actually bring in profitable work. Tracking each enquiry through to a paid, completed job in Trade2Base shows you which render types and which lead sources make you the most money — so you can lean into the work that pays and stop chasing the work that doesn't.

Whole-House Examples

Customers rarely think in per-m² rates — they want to know what their house will cost. As a guide, a typical render area is roughly 80–120m² for a terraced house, 120–180m² for a 3-bed semi and 180–280m² for a detached, before you add scaffolding. That puts a re-rendered 3-bed semi in silicone at roughly £4,000–£10,000+ once prep and access are included, with cheaper sand and cement at the lower end and EWI well above it.
