Silicone Render Cost: A Full UK Breakdown for 2026

What does silicone render cost?

Here’s the figure most people come for, given as an honest, indicative range for 2026: silicone render typically costs around £45–£80 per square metre fitted, with a typical 3-bed semi commonly landing somewhere around £5,000–£10,000 all-in. That’s a wide band on purpose, because the real number for your home depends heavily on the specific wall and access — two similar-looking houses can attract genuinely different quotes for sound reasons.

Treat these numbers as a sense-check to plan around, not a price you can hold anyone to. The purpose of this guide is to show you what sits behind the range so you can understand your own quotes rather than just react to them. We’ll break the cost down per square metre and by house size, then work through every variable that moves it — and finish with how to read competing quotes properly. If you want the brand-specific angle, our K-Rend cost guide covers the premium-brand version of the same picture.

Silicone render cost per square metre

The square metre is the building block of every render quote, so it’s worth understanding. As an indicative figure, fitted silicone render runs about £45–£80/m², covering labour, materials, the base coat, mesh, primer and topcoat — though not always scaffolding, which is sometimes quoted separately. Where a job lands in that band depends mostly on the wall’s condition and the access, which we come to shortly.

Silicone render cost by house size

Most homeowners think in whole-house terms, so here are indicative all-in ranges by property type. These assume a reasonably sound wall and normal access; remove old render or add tricky access and you move toward the top of each range or beyond.

indicative A terrace is cheaper partly because neighbours shelter the side walls, leaving less area to render; a detached house has four exposed elevations and more scaffolding. For the whole-market view across render types see our cost to render a house guide.

What affects the price

This is the part that explains why quotes differ, and it’s rarely the render. The biggest factor by far is the condition of the existing wall: rendering over a sound surface is straightforward, but if old, failing render has to be hacked off first, that’s extra labour, waste disposal and time. After that come scaffolding and access, the finish (dry-dash uses more material than a scraped finish), the amount of detailing around bays, sills and features, and plain regional labour rates, which vary noticeably across the UK.

Notice what’s not top of that list: the brand of render. The difference between a premium branded silicone and a quality generic one is usually a modest slice of the total, dwarfed by the wall, the access and the labour. So when one quote is hundreds or thousands more than another, the productive question is which of these variables explains it — not whether someone is using a fancier bag of render. The next few sections take the big ones in turn.

The big variable: removing old render and prep

If there’s one line that swings a silicone render quote, it’s whether the old surface stays or goes. Hacking off failing render is messy, labour-intensive work that can add roughly £1,000–£4,000 to a job depending on the house, plus waste disposal. It’s also sometimes unavoidable: applying fresh render over a loose, hollow or unsound surface just means the new finish fails with the old one underneath it.

This is why two identical-looking houses can be quoted very differently — one may have a sound wall ready to take render, the other a layer of dying pebbledash that has to come off first. It’s also why a quote that’s notably cheaper is worth questioning: make sure it isn’t simply assuming no preparation that the wall actually needs. Good preparation is invisible in the finished job but decisive for how long it lasts, so it’s the wrong place to save money. A proper survey is what determines whether hack-off is needed.

Scaffolding and access costs

Render is applied at height across whole elevations, so scaffolding is almost always required and it’s a real cost in its own right — sometimes quoted within the per-m² rate, sometimes as a separate line. The amount needed depends on the height and footprint of the house and how easy it is to access: a detached house with four storeys-worth of elevations and awkward boundaries needs far more than a simple bungalow.

Access complications push it further. Restricted side access, conservatories or extensions to scaffold around, sloping ground, or being on a busy road that needs pavement licences all add to the bill. None of this is the renderer padding the quote — it’s the genuine cost of getting safe, legal access to your walls. When comparing quotes, one of the first things to check is whether scaffolding is included or extra, because a per-m² rate that excludes it can look cheaper while ending up dearer.

The labour-versus-materials split

A common surprise for homeowners is how the money actually divides. On most silicone render jobs, labour is the larger share of the bill, with the render materials a smaller slice than people assume. Rendering is skilled, time-consuming work — preparation, base coat, bedding the mesh, curing time, primer, then the finish — and that craftsmanship, plus the scaffolding time, is where much of the cost sits.

This matters for two reasons. First, it’s why trying to save money by specifying a cheaper bag of render barely moves the total — you’re shaving a small input, not the big one. Second, it explains why a suspiciously cheap quote should worry you: if the labour-heavy parts are being priced low, something is usually being rushed or skipped, and those are the hidden layers that determine whether the render lasts. Paying a fair rate for skilled labour is the best value in the whole job.

Does the render brand affect the cost?

A little, but less than you’d think. A premium brand such as K-Rend typically sits toward the upper end of the silicone price band, while a quality generic silicone from another reputable manufacturer can come in slightly lower on materials. But because materials are a minority of the total and the brand premium is a fraction of that, the difference to the final bill is usually modest — a few per cent, not the headline.

So if you’re trying to control cost, the brand is a minor lever compared with the wall, the access and the labour. What you’re really paying the premium for with a big-name brand is recognition, a wide installer network and a manufacturer guarantee — we weigh that up in K-Rend vs silicone render. The practical takeaway: choose a quality system and a good installer, and don’t expect switching brands to transform the price.

Does the finish affect the cost?

Yes, modestly. The fine scraped texture — the smooth, even look on most modern rendered homes — is the standard and usually the baseline price. A dry-dash (roughcast) finish, where aggregate is thrown into the surface, uses more material and a different technique, so it can add a little to the cost. The colour you choose generally doesn’t change the price, since the render is through-coloured either way — though very dark shades occasionally carry a small premium.

The finish is more a decision about looks and upkeep than about budget, and the cost difference between scraped and dry-dash is rarely the deciding factor. If you’re weighing the two, our guide to textured versus smooth render covers the trade-offs in appearance and maintenance. For most homeowners the finish is chosen on style, with cost a minor consideration rather than a driver.

Hidden costs to watch for

The gap between quotes often hides in what’s not stated. Make sure each quote clearly includes the things a proper job needs: a quality base coat, full reinforcing mesh, primer, and beads at corners and edges — these aren’t optional extras, they’re part of a sound system. Check too whether scaffolding, removal of old render, and making good afterwards (cleaning up, reinstating anything moved) are in the price or billed separately.

Two more to confirm: VAT, since a quote that excludes it will be 20% higher than it looks, and any repairs to the wall uncovered once work starts. A transparent quote spells all of this out; a vague one leaves room for the bill to climb. When a quote looks cheap, it’s usually because one or more of these has been left out — so the cheapest headline figure and the cheapest finished job are often not the same thing.

Cheaper alternatives — and false economies

If silicone render stretches the budget, there are genuinely cheaper render systems worth knowing about. Monocouche render is also through-coloured and often a little cheaper, though generally less water-repellent. Cement-and-sand render is cheaper still, but it isn’t through-coloured, so it brings ongoing maintenance. Each is a legitimate option where it suits the wall and the budget — the point is to choose a cheaper system deliberately, not to cut corners within a silicone job.

The false economies are the ones to avoid. Skimping the base coat or mesh to lower a silicone quote stores up cracking that costs far more to put right than was saved. And the cheapest headline quote frequently turns out dearest once the omissions surface. The honest rule: if you need to spend less, step down to a cheaper render type with eyes open — don’t buy a silicone job that’s been quietly hollowed out to hit a price.

How to read and compare quotes

The single most useful skill here is comparing like with like. Before judging on price, line the quotes up and check they cover the same scope: the same wall area, the same preparation (including any hack-off), scaffolding in or out, the same system (base coat, mesh, primer, finish), and VAT treated the same way. A quote that’s cheaper because it quietly excludes scaffolding or assumes no preparation isn’t really cheaper — it’s answering a different question.

Once they’re on equal terms, price becomes meaningful, and you can weigh it against the things that don’t show on the invoice: the installer’s track record, the workmanship guarantee, and how clearly they’ve specified the hidden layers. Our checklist on choosing a rendering contractor and our guide to render guarantees cover that side. The aim is to pick the best value, which is rarely the lowest number and never the highest by default.

Budgeting and final thoughts

To plan sensibly, take the indicative range for your house type, lean toward the upper end if you suspect old render needs removing or access is awkward, and add a contingency for anything the survey uncovers once work starts — older walls in particular can hold surprises. Build in scaffolding and VAT from the outset so the real figure isn’t a shock, and remember the cost is buying you a finish you’ll live with for 20 to 30 years, not a short-term fix.

Above all, resist the pull of the cheapest quote for its own sake. The best value in rendering is a complete, properly specified job done by a skilled installer at a fair price — because that’s the one that lasts and doesn’t come back to cost you again.
