Branded render system

K Rend Cost per m² and by House Size

Plan a K Rend project without confusing one brand with one fixed build-up, finish or all-in square-metre rate.

Direct answer

Current UK observations place general house rendering around £30–£80 per m², while Checkatrade uses about £72.50 per m² as a current silicone-render benchmark and about £10,000 for three walls of an average semi-detached house. K Rend is a brand with different systems, so the quote must name the exact product build-up and state whether preparation, mesh, scaffold, waste and VAT are included.

K Rend-style project cost calculator

Start with the measured 100m² example, then change the area, generic system, wall condition, access and region. The result is free before contact details. Monocouche and silicone are planning categories, not verified prices for a particular K Rend product or complete manufacturer specification.

Use net facing-wall area after measuring the elevations and deducting substantial openings.

  • Evidence reviewed 14 September 2026; the source register distinguishes render-system rates from access allowances.
  • Confirm removal, repairs, beads, scaffold, waste, insulation, paint and VAT in the written quote.
  • Planning and building-control requirements depend on the property and scope.
This uses the unchanged general render model, not a local quote, product recommendation or K Rend approval. The scaffold allowance and condition adjustment do not establish the cost of stripping, repairs, insulation, decoration or VAT. Confirm a compatible named system and written inclusions with the installer.

What changes the result?

A useful calculation starts with the physical scope and the written commercial terms. These are the factors to make explicit:

  • Exact K Rend system and finish
  • Measured elevation area and openings
  • Existing render removal and substrate repairs
  • Base coat, reinforcement, beads and primer
  • Scaffold, protection, waste and VAT

Use one scope for every quote

Give each business the same information and ask it to resolve the same boundaries. That makes the totals more comparable and exposes work left as an allowance or exclusion.

  1. Ask for the exact manufacturer specification
  2. Compare measured net and gross areas
  3. Separate substrate repairs and access
  4. Require colour, texture and sample approval

Use the headline rate as a planning check

MyBuilder's current national house-rendering observation is roughly £30–£80 per m². Checkatrade's current K Rend guidance points to its £72.50 per m² silicone-render benchmark and an approximately £10,000 three-wall semi-detached example.

Those figures do not prove that two quotes include the same wall preparation, access or branded system. Use the calculator's monocouche scenario as a starting point, then replace every assumption with the contractor's measured scope.

K Rend is not one generic material

The brand covers different cement-based, silicone and thin-coat products with product-specific backgrounds, base coats, reinforcement, primers, application depths and finishes. Ask the installer to identify the exact named components and confirm they form one compatible specification.

For example, the manufacturer's Silicone K1 page gives different consumption for application to 7-newton block and over a base coat. Silicone TC 15 is a ready-mixed thin-coat product: its roughly 10m² per 25kg bucket describes the finish, not a complete installed wall system. These products and coverage figures are not interchangeable.

Do not accept a quote that uses ‘K Rend’ only as a colour or marketing label. The written scope should describe the substrate assessment, removal, repairs, beads, mesh locations, base preparation and final texture. The calculator does not select an appropriate product or installation specification.

Normalize the full exterior project

Record every elevation, extension, gable, parapet, reveal, plinth, sill, pipe and awkward boundary. State how openings are measured and whether protection, scaffold, waste, making good and VAT are in the total.

Planning Portal's external-wall guidance relates to England and highlights circumstances where permission may be needed, including protected areas and listed buildings. Check with the relevant local authority before work; this estimate does not determine planning permission, building-control compliance or a wall's suitability for rendering.

Measured K Rend-style budget examples

These examples reproduce the existing calculator's model arithmetic, not new K Rend quotations or local market averages. The underlying rates and adjustments were reviewed on 14 September 2026; this page's sources were rechecked on 4 October. Measure the net area of the elevations rather than using the home's floor area or bedroom count.

  • 50m², generic monocouche, sound walls, typical regional band and ground-level or already-provided access: £2,500–£4,000 (50 × £50–£80 per m²).
  • 100m² with the same assumptions: £5,000–£8,000. There is no extra scaffold allowance in this example; that does not mean all real projects need no scaffold.
  • The opening 100m² example uses patchy walls (a modeled 1.18× adjustment) and full-house access (£1,000–£4,000 allowance): £6,900–£13,440. This does not price a survey, stripping every wall or major substrate repairs.

Turn a price check into one rendering project brief

Change the area, generic render system, condition, access and region above, then calculate your budget. The result is free before contact details. Copy or print the project brief, or choose the optional quote request to carry your measurements and estimate forward without entering them again.

Add the proposed K Rend product, colour, finish, elevations, existing wall condition and useful photos or notes to the quote request. We check postcode and service availability before matching; a nearby installer, manufacturer approval and a fixed number of quotes are not guaranteed. No brand partnership is implied.

Questions people ask

How much does K Rend cost per square metre?

Current UK planning evidence places general rendering around £30–£80 per m², while Checkatrade uses about £72.50 per m² as a silicone-render benchmark. Exact K Rend system, preparation, scaffold and region determine the quote.

How much is K Rend for a semi-detached house?

Checkatrade currently uses about £10,000 for three walls of an average semi as a silicone-render comparison. Measured wall area, access, substrate condition and named system are more reliable than property type alone.

Is scaffolding included in K Rend prices?

Not consistently. Require scaffold or other access to be explicitly included or separately priced for every elevation.

Can K Rend go over existing render?

Only after the existing background has been assessed as suitable for the specified system. Loose, cracked, painted or damp surfaces can require removal, repair or a different preparation.

How much is 100m² of K Rend?

The generic monocouche model gives £5,000–£8,000 for 100m² of sound walls in the typical regional band with ground-level or already-provided access. With patchy walls and the full-house scaffold allowance, it gives £6,900–£13,440. Neither result is a product-specific K Rend quotation; name the complete system and confirm every inclusion.

Is a K Rend bag or bucket price the installed cost?

No. Product coverage depends on the named finish and background. A finish-only purchase does not include a complete base-coat system, primer, reinforcement, labour, wall repairs, access or other project costs.

Can I request K Rend quotes near me?

After calculating a free estimate, you can carry your brief into an optional rendering quote request with your postcode and proposed product details. We check coverage and suitability before matching; nearby availability, manufacturer approval and a guaranteed number of quotes are not promised.
