How Much Does K-Rend Cost? 2026 UK Price Guide

How much does K-Rend cost in the UK?

Let’s start with the figure you came for. As an indicative 2026 guide, K-Rend is commonly priced at indicative £45–£80 per square metre fitted, with most straightforward jobs landing in the middle of that band. Translate that to whole properties and you get the ranges below. They assume a sound wall and standard access; the next sections explain what moves a quote up or down.

indicative Ballpark ranges to help you budget, not fixed prices. They include scaffolding and a sound substrate but exclude hacking off old render where that’s needed. For the wider picture across every finish, see our cost to render a house guide.

It’s worth saying plainly: a quote noticeably below these ranges usually has something missing — no scaffolding, no mesh, thin preparation, or an inexperienced crew — and a quote well above them isn’t automatically better. The value is in what’s specified, which is exactly what we’ll help you read.

What a K-Rend quote should include

The word “render the house” can hide a multitude of differences, which is why two quotes for the “same” job can be thousands apart. A complete, like-for-like K-Rend quote should set out each of these as a line you can see:

Scaffolding for safe access to every elevation; surface preparation (cleaning, or hacking off and disposing of old render); beads at corners, stops and sills; the base coat with reinforcing mesh bedded in; a primer; the through-coloured topcoat in your chosen finish; making good around fixtures and reveals; and clearing and cleaning on completion. If you can’t see scaffolding and mesh on a quote, ask — they are not optional, and leaving them out is the easiest way to make a number look cheap.

It also helps to know what a quote shouldn’t leave vague. “Prep as required” or “render to all walls” with no detail is a warning sign — it leaves the contractor free to interpret the scope later, usually in their favour. A good quote names the system and range being used, states the finish and colour, and is explicit about what happens if the substrate is worse than expected once any old render is off. Getting that contingency agreed in writing up front is what stops a mid-job “extra” turning into a dispute.

What affects the price most

If you understand the handful of factors below, you’ll understand almost every difference between quotes.

The condition of the existing wall is the single biggest swing. Rendering over a sound surface is quick; if old, blown render has to be hacked off, bagged and skipped first, that’s days of extra labour and disposal — commonly £1,000–£4,000 on its own. Scaffolding, access and storeys come next: a detached bungalow you can walk around is far cheaper to scaffold than a three-storey townhouse or a terrace with no rear access. The finish matters too — a dry-dash finish uses more material and time than a scraped one. So does the amount of detailing around bay windows, sills, porches and decorative features, each of which slows the work. Finally, regional labour rates are real: the same job costs more in London and the South East than in much of the North.

Our companion guide on how render is priced per m² shows how these stack up so you can sanity-check a quote line by line.

One factor worth understanding is the substrate type itself. A sound, even brick or blockwork wall is the ideal base and prices keenly. An existing render in good condition can often be rendered over, but if it’s hollow or failing it has to come off. Pebbledash is case-by-case — sometimes a sound base, sometimes a removal job. And non-standard construction — timber frame, system-build or previously-insulated walls — needs a specific specification and can’t be priced like ordinary masonry. A surveyor identifying your wall type accurately is the difference between a quote that holds and one that balloons mid-job.

How finish and colour affect the cost

Two choices within the render itself nudge the price, though neither dominates. The finish is the bigger of the two: a scraped texture — the smooth, even look on most modern homes — is the standard and the most economical, while a dry-dash (roughcast) finish typically adds in the region of 10–20% because it uses more material and takes longer to apply well. If you’re torn between the looks, our guide to textured versus smooth render weighs them up beyond just cost.

Colour has far less impact. A shade from the standard palette usually costs nothing extra, whereas a bespoke colour match to a specific reference may carry a small materials premium and need ordering in. It’s worth choosing your colour early so a non-standard shade can be priced and sourced up front rather than becoming a surprise — our K-Rend colours guide covers how to pick one you won’t regret.

New render vs rendering over what's there

Whether your wall keeps its existing surface makes a big difference to the bill. Rendering over a sound substrate — clean, stable brick or an existing surface in good order — is the cheaper route, because there’s no removal. Hacking off and starting again is dearer but sometimes unavoidable: if the current render is blown, cracked or poorly bonded, applying a new system over it just buries the problem and it will fail again. A good surveyor will tap and inspect the wall and tell you honestly which situation you’re in. If you have pebbledash, it may be possible to render over it when it’s sound, or it may need removing — the right answer depends entirely on its condition.

Does the K-Rend brand cost more?

People often assume the K-Rend name carries a big premium. In practice the difference is modest and usually swamped by the labour and access costs that dominate any render job. A good-quality generic silicone render from another reputable manufacturer may shave a little off the materials, but it won’t transform the total, because most of what you’re paying for is skilled time on scaffolding. The honest takeaway is that your installer and specification move the price — and the quality — far more than the brand does. We compare the two directly in K-Rend vs silicone render.

How K-Rend cost compares to other renders

K-Rend doesn’t sit in a vacuum, and seeing it next to the alternatives helps you judge whether it’s the right spend. As a rough, indicative guide for a like-for-like job:

indicative Ranges overlap heavily because the property, not the product, drives most of the cost. The headline lesson is that cement render looks cheapest until you add years of repainting, while through-coloured systems cost more up front and then largely look after themselves. The full picture is in cost to render a house.

The extra costs people forget

The headline render price isn’t always the whole story, and a careful homeowner budgets for the extras. Hacking off old render and repairing the substrate beneath it can be the largest of these, and you often can’t know the full extent until the old surface is off. Awkward access — over conservatories, extensions or into tight alleys — can add scaffolding cost. Removing and refitting items such as downpipes, satellite dishes, alarm boxes and outside lights, plus making good afterwards, takes time. And remember that quotes from VAT-registered firms include VAT while a smaller trader’s might not — check, so you’re comparing like with like. None of these are reasons to worry; they’re reasons to ask for an itemised quote.

Is K-Rend worth the cost?

For the right home, the value case is straightforward. Because K-Rend is through-coloured it never needs repainting, so unlike the painted cement render it replaced there’s no recurring decorating bill every few years. It can lift kerb appeal dramatically, modernising tired or mismatched brickwork, and a well-applied system lasts 20–30 years with little more than an occasional wash. Whether that translates into resale value depends on your property and market — we look at the evidence in does rendering add value. The key is that the spend only pays off if the work is done properly; a cheap, poorly-applied job is the one way to lose money on render.

The whole-life cost a quote won't show you

A render quote is a single number for a single moment, but the real cost of a finish plays out over decades — and that’s where K-Rend earns its premium back. The painted cement render it replaced needs repainting roughly every five to ten years, and each repaint means paint, labour and scaffolding all over again. Across a 25-year span that recurring bill can quietly add up to more than the original render cost.

A through-coloured system sidesteps that cycle. There’s no repainting, and ongoing upkeep is usually limited to an occasional wash to lift surface algae or grime — a modest, infrequent cost rather than a standing one. When you’re comparing a cheaper finish against K-Rend, it’s worth mentally adding those future maintenance rounds to the cheaper option before deciding which is actually the lower spend over the time you’ll own the home.

What's a normal payment structure?

Knowing what’s customary protects you from the rare contractor who isn’t. For a job of this size, it’s normal to pay a modest deposit to secure the booking and cover initial materials, then stage payments as the work progresses — for example once scaffolding is up and preparation is done — with the balance on satisfactory completion. What you should be wary of is any request for a large upfront sum before work begins, or pressure to pay the full amount in cash before you’ve seen the finished result. A reputable specialist will set the payment terms out clearly in writing alongside the specification, and will be comfortable explaining them. If a deal hinges on a big cash payment today, treat that as a reason to pause, not to rush.

How to get an accurate quote

A reliable price comes from a survey, not a phone estimate. Any quote given without someone seeing the wall is a guess, because the wall is the variable. Aim to get two or three written quotes, each with an itemised specification, so you’re comparing the same scope. Ask each contractor what’s included, what’s excluded, what happens if the substrate is worse than expected once the old render is off, and what guarantee is offered. Our checklist on choosing a rendering contractor sets out the questions worth asking.

How to save money without cutting corners

Two more levers are worth knowing. First, do the whole house at once rather than one elevation at a time — you only pay to erect scaffolding once, and a single colour batch guarantees a consistent finish across every wall. Phasing the job almost always costs more in total. Second, be ready to decide: having your colour chosen, access sorted and any fixtures you want removed dealt with before the crew arrives keeps the job moving and avoids costly standing time. Efficiency on your side is a genuine, no-compromise saving.
