Render Costs UK — What to Charge for External Wall Rendering in 2026

Render Types and Supply-and-Fit Costs per Square Metre

The single biggest factor in your quote is the render system you're specifying. Each system sits at a different price point and carries a different labour-to-materials ratio. Here are the main systems and their realistic 2026 supply-and-fit rates across the UK, excluding scaffold.

Traditional Sand and Cement Render — £25–£40/m²

The original external render. A three-coat system — scratch coat, float coat, and finish — applied directly to masonry. Materials are cheap: a tonne of sharp sand costs £60–£90 delivered, and a 25 kg bag of Portland cement is around £8–£10. Labour is the main cost driver, and this system requires more time on the wall because you're waiting for each coat to cure before applying the next.

At £25–£40/m², a typical 2-man crew can cover 30–40 m² per day on good brickwork that has been primed and prepared. The lower end of the rate applies to large flat elevations with no reveals or detail; the upper end applies to awkward gables, multi-storey work, or buildings with lots of window and door openings. Traditional cement render needs painting every 5–8 years, which is worth making clear to customers when they are comparing it against premium systems.

Monocouche Render (K-Rend, Weber.pral M) — £40–£60/m²

Monocouche — French for single layer — is a factory-blended through-colour render that goes on in one coat, typically 15–20 mm thick, and is scraped back to aggregate to create a textured finish. The leading brands are K-Rend (Saint-Gobain) and Weber.pral M (Saint-Gobain Weber). Both carry BBA certification and a 25-year system guarantee when installed to specification.

Material cost for K-Rend is around £10–£14 per 25 kg bag, covering roughly 2.5–3 m² at full depth. A typical job uses 1 bag per 2.5 m², so material cost runs at £4–£6/m² for the render alone. The premium over sand-and-cement is accounted for by higher material cost and slightly slower application, but the system saves time on painting — there is none, ever. That is a significant selling point for customers who want a low-maintenance finish. Charge £40–£60/m² supply and fit, depending on complexity.

Silicone Render (K-Rend Silicone K1, Weber Silicone TC) — £50–£75/m²

Silicone thin-coat render is the premium domestic system. Applied at 1.5–2 mm over a base coat and mesh, it is hydrophobic, self-cleaning, highly flexible, and breathable. The two most commonly specified products in the UK are K-Rend Silicone K1 and Weber.rend silicone TC, both available in dozens of through-colours with the option of bespoke tinting.

The price reflects the full system: base coat, fibreglass mesh reinforcement, primer, and silicone topcoat. A 25 kg tub of silicone topcoat covers roughly 20–25 m² and costs £80–£120 depending on supplier and colour. The base coat is an additional £4–£6/m². Labour intensity is higher than monocouche because the mesh and primer stages add time. At £50–£75/m², silicone is your highest-margin domestic system if you are efficient. On a 100 m² house you are looking at £5,000–£7,500 for the render element alone before scaffold.

Silicone render carries a manufacturer guarantee of 20–25 years and requires no painting for the life of the building — that guarantee is a significant differentiator when competing with painters who are quoting re-painting tired pebbledash every few years.

Acrylic Render — £35–£55/m²

Acrylic is a polymer-modified thin-coat finish, typically 1.5–3 mm thick, applied over a base coat. It is more flexible than traditional cement render and offers good colour retention, though it is not as hydrophobic as silicone. It is widely used on EWI (External Wall Insulation) systems as the decorative topcoat. Material cost is slightly below silicone, and application speed is comparable. Charge £35–£55/m² supply and fit for acrylic as a standalone render system on masonry.

Mineral Render — £40–£65/m²

Mineral render sits between monocouche and silicone in terms of performance. It is cement-based but factory-coloured, breathable, and fire-resistant — making it the system of choice for new-build developers and social housing where fire performance certification is required. Weber.min M and K-Rend Mineral are the typical specifications. The finish requires a silicone-based impregnation coat (hydrophobisation) after application to bring it up to a comparable water-resistance to silicone thin-coat. Charge £40–£65/m² supply and fit, noting the hydrophobisation treatment is included.

EWI (External Wall Insulation with Render Finish) — £80–£150/m²

EWI is a full system: rigid insulation boards (typically EPS or mineral wool) are mechanically fixed and adhesively bonded to the substrate, followed by a base coat with reinforcing mesh, primer, and a render finish — usually silicone or acrylic. The insulation element means material cost is substantially higher: 100 mm EPS board alone runs at £6–£12/m² supply; mineral wool at £10–£18/m². Labour time roughly doubles versus a straight render job because of the fixing, tracking, and corner bead work.

EWI is frequently funded partly through government retrofit schemes (ECO4) where the property owner qualifies, which can help you sell the project. Charge £80–£150/m² supply and fit depending on insulation thickness, system specification, and the condition of the existing substrate. Large straight-sided new-build blocks come in at the lower end; older housing with projecting features comes in at the upper end.

Cost Per Job: What Whole-House Rendering Actually Costs

Square metre rates only tell part of the story. When customers ask "how much to render my house?" they want a figure. Here are realistic total job costs for two common property types, excluding scaffolding, based on 2026 UK rates.

Small Semi-Detached (Approximately 60 m² of Wall)

A typical 1930s or 1950s semi-detached with two storeys and a simple rear extension will have around 55–65 m² of wall once windows and doors are deducted. Using 60 m² as the working figure:

• Traditional sand and cement: £1,500–£2,400 render, £800–£1,600 scaffold = £2,300–£4,000 total
• Monocouche (K-Rend / Weber): £2,400–£3,600 render, £800–£1,600 scaffold = £3,200–£5,200 total
• Silicone thin-coat (full system): £3,000–£4,500 render, £800–£1,600 scaffold = £3,800–£6,100 total

If pebbledash removal is required first, add £900–£1,500 for the hack-off on 60 m².

Large Detached (Approximately 150 m² of Wall)

A four-bedroom detached house with a garage, porch, and bay window will typically have 130–170 m² of renderable wall. Using 150 m²:

• Traditional sand and cement: £3,750–£6,000 render, £1,500–£2,500 scaffold = £5,250–£8,500 total
• Monocouche: £6,000–£9,000 render, £1,500–£2,500 scaffold = £7,500–£11,500 total
• Silicone thin-coat (full system): £7,500–£11,250 render, £1,500–£2,500 scaffold = £9,000–£13,750 total

These are supply-and-fit figures including prep, materials, and labour. VAT at 20% applies to all residential rendering unless the property qualifies for reduced-rate VAT under the energy-saving materials rules — which applies to EWI but not standard render.

Labour Rates: What Renderers Charge Per Day

A skilled renderer in the UK currently charges £180–£280 per day as a day rate. The range reflects geography (London and South East at the top, Wales and North East at the lower end), experience, and whether the individual is CSCS-carded and system-trained (K-Rend and Weber run their own applicator training programmes, and trained applicators command the upper end of the scale).

Domestic render jobs almost always run as a 2-man crew: one lead renderer and a labourer or second renderer. The labourer mixes, carries, and preps; the renderer applies. A 2-man crew costs £320–£520 per day inclusive of both operatives. On a monocouche job with good access, a 2-man crew should achieve 30–45 m² per day. On a silicone system with base coat, mesh, primer, and topcoat as separate operations, expect 20–30 m² of completed wall per day.

As a contractor, your all-in day rate (including employer NI, holiday pay, and vehicle costs if operatives are employed) will be higher than the bare day rate — factor 1.25–1.4x the nominal day rate when costing employed labour.

Why Silicone and Monocouche Cost More — and Why Customers Should Pay It

The most common objection to a premium render quotation is the price difference versus painting pebbledash or applying a standard cement finish. Here is the case for the higher specification, expressed in terms a homeowner understands.

Traditional sand and cement render needs decorating every 5–8 years to maintain appearance and weatherproofing. A 150 m² house costs £1,200–£2,500 to paint externally, meaning the homeowner spends £6,000–£12,500 on painting alone over a 25-year period — on top of the original render cost. Silicone and monocouche require no painting for their lifetime. Over 25 years, the premium specification is typically cheaper in whole-life terms even before accounting for the improved weatherproofing and the manufacturer guarantee.

Silicone render is hydrophobic — water beads and runs off rather than being absorbed — which significantly reduces the risk of frost damage, algae growth, and efflorescence. The 20–25 year system guarantees offered by K-Rend and Weber are backed by BBA certification, which is increasingly required by mortgage lenders and insurers.

As a contractor, quoting the premium system with a clear whole-life cost explanation improves your close rate on higher-value jobs and protects your reputation — silicone render that is installed correctly does not fail, whereas cheap sand-and-cement render on a poorly prepared substrate will crack and delaminate within a few years and come back to bite you.

Preparation Costs: What Goes in Before the Render

Preparation is where many rendering quotes fall short. A quote that covers render supply and fit but ignores hacking off, substrate repair, and priming will blow your margin the moment you start work. Price every element separately.

Pebbledash and Old Render Removal — £15–£25/m²

Hacking off old pebbledash or failed render is physically demanding, time-consuming work. The rate of £15–£25/m² reflects hand removal; mechanical removal (SDS hammer chisels, wide chisels) is faster but generates large quantities of waste that must be bagged and skipped. Allow for skip hire — a 6-yard skip costs £250–£400 in most of England. If the property is in a conservation area or listed, check whether removal of original render requires consent before pricing.

Substrate Repair and Priming

After hack-off, the substrate will need inspection. Damaged or friable mortar joints need raking out and repointing. Spalled bricks need cutting out and replacing. Stained or contaminated areas need treatment. Budget £500–£1,500 on a typical semi-detached for substrate repairs depending on condition; significantly more on older properties with lime mortar joints.

Priming is not optional on most premium render systems — K-Rend, Weber, and EWI all require a system primer applied to the clean substrate before the render. K-Rend Primer K101 covers around 5–6 m² per litre. Allow £100–£250 for primer on a 60 m² semi.

Bead and Mesh

Stop beads, angle beads, movement beads, and window sill trims are essential for a neat, durable finish. Material cost for beads on a whole house typically runs £150–£400 depending on the amount of openings and the number of movement joints required. On EWI systems, fibreglass mesh is embedded in the base coat at 160–165 g/m² — allow £0.80–£1.50/m² for mesh material.

Scaffolding: What to Allow and How to Quote It

Scaffolding is the line item that most homeowners push back on — and the one that is non-negotiable for anything above a single-storey extension. In 2026, scaffolding costs in the UK are:

• Single-storey elevation (up to 3 m): £400–£700 erected, standing for up to 2 weeks
• Two-storey house (up to 6.5 m): £800–£1,500 for a typical 4-elevation wrap
• Three-storey or large detached: £1,500–£2,500 or more
• Additional hire beyond 2 weeks: £80–£200 per week depending on size

Always obtain a firm quote from your scaffolding contractor before you submit your render quote — do not use an allowance. Scaffold costs vary significantly with access, proximity to a road, whether the property has a shared boundary, and whether birdcage scaffold is needed around projecting elements like bay windows.

Include scaffolding as a named line on your quote rather than burying it in a total. Customers who see a transparent breakdown are less likely to challenge individual items; an opaque lump sum invites negotiation on everything.

Planning Permission and Building Regulations

External rendering does not usually require planning permission in England and Wales. It is treated as a change of material to the external finish and falls within permitted development rights, provided the dwelling is not in a designated area and the new finish is not of a type that would materially affect the appearance of the building in a way that requires consent under local planning conditions.

There are exceptions: if the property is a listed building, any change to the external finish requires listed building consent regardless of the render type. If the property is in a conservation area, Article 4 directions in many local authorities remove permitted development rights for changes to external materials, requiring a householder application. Always advise the customer to check with their local planning authority before you start on listed or conservation area buildings — this protects you as well as the customer.

EWI systems that increase the thickness of the external wall by more than 100 mm close to a boundary may require planning permission. EWI also affects the thermal performance of the building and, where it is installed as part of a project to improve compliance with Part L of the Building Regulations, Building Control notification may be required. This is most likely to arise on new build or major refurbishment projects rather than domestic re-rendering.

What Goes in a Render Quote: A Full Breakdown

A professional rendering quote should itemise every cost element so the customer understands what they are paying for and you have a clear record of what you priced. The key sections are:

• Area measurement: Total gross wall area measured at each elevation, with deductions for windows and doors stated separately. Show the net rendereable area in m².
• Preparation: Hack-off (if applicable), substrate repair, priming — quoted separately per m² or as a fixed sum with scope defined.
• Materials: Render system specified by brand and product (e.g. K-Rend Silicone K1 in Limestone, 1.5 mm texture), quantity in bags or kg, unit rate.
• Labour: Number of operatives, estimated duration in days, day rate or fixed price for the render application stage.
• Beads and fixings: Angle beads, stop beads, movement beads, mesh (if applicable).
• Scaffolding: Contractor name, fixed price for erect-and-dismantle, weekly hire rate if the job extends beyond the quoted standing period.
• Skip hire: If hack-off is included, state skip size and anticipated number of loads.
• VAT: State the rate applied (standard 20% for most residential render work).
• Total: Ex-VAT subtotal and inclusive total clearly shown.

Include a specification note describing the system, the number of coats, the substrate requirements, and any warranty or guarantee that applies. This becomes part of the contract and protects you if a customer later claims the finish is not what they expected.

Quoting Tips for Rendering Contractors

Measure at Height, Not from the Ground

The most common measuring mistake is using a single height figure for the whole elevation. A two-storey house is not simply 5 m high at every point — gables continue to the ridge, and bay windows have returns. Where possible, measure each section separately and confirm your total against the scaffold board count once the scaffold is up. A 10% error on a 150 m² job at £60/m² is £900 off your margin before you have started.

Deduct Windows and Doors Consistently

Standard practice is to deduct openings over 0.5 m². Do not deduct openings under 0.5 m² — the labour to render around reveals often exceeds the saving from the reduced area. Apply your deduction consistently and state your methodology on the quote. Most render contractors measure gross area and apply a 10–15% deduction for openings on a typical house rather than measuring every opening individually — this is acceptable practice but works against you on buildings with large glazing areas. Measure individually on glazed extensions and commercial elevations.

Allow for Reveals, Soffits, and Detailing

Window and door reveals, soffits to flat-roof extensions, render bands, quoins, and string courses all take disproportionate time relative to their area. If a job has extensive detailing, add a fixed sum to cover the additional time rather than trying to capture it in the m² rate. A property with twelve windows, two bay windows, and a rendered parapet wall is not the same job as a flat-sided industrial unit at the same m² count.

Price the System, Not Just the Product

Both K-Rend and Weber offer free CPD-accredited training for applicators, and trained applicators can apply for system guarantees that are backed by the manufacturer. If you are quoting a premium system, make clear that you are a trained applicator (if you are) and that the guarantee is available subject to registration. This differentiates your quote from a competitor quoting a similar finish without the system knowledge and is often the reason a premium quote wins over a cheaper alternative.

Build in a Risk Allowance on Strip and Prep

Prep is where rendering jobs lose money. You do not know the full condition of the substrate until you have hacked off the existing render. If the brickwork is spalled, if there are salt deposits, if the original render was bonded directly to friable masonry, the prep scope expands significantly. Quote a clear scope for prep and include a change-control clause that allows you to price additional work if the substrate condition is worse than anticipated. This is standard practice on commercial contracts and is increasingly accepted on domestic work.
