Cladding Installation Costs UK — What to Charge for External Wall Cladding in 2026

Types of External Wall Cladding — Cost Per m² Supply and Fit

All figures below are supply and fit, including basic preparation on a sound substrate. They exclude scaffolding (priced separately), deep substrate repair, and thermal insulation layers unless stated.

Render / Monocouche — £40–£80/m²

Traditional sand and cement render sits at £40–£55/m² for a two-coat system with a smooth or scraped finish. Monocouche (single-coat through-colour render, brands like Weber Pral M or K Rend) runs £55–£80/m² supply and fit. Monocouche commands a premium because it's factory-blended, colour-stable, and faster to apply once you have a trained crew. On a semi-detached with 90m² of external wall, expect a render job to price at £3,600–£7,200 plus scaffold. Key cost drivers: number of coats, bead count (corners, reveals, expansion joints), and whether mesh reinforcement is required over block-to-brick junctions.

Timber Cladding (Featheredge, Larch, Cedar) — £60–£120/m²

Treated featheredge board is the cheapest option at £60–£75/m² fitted, typically used on garden buildings and agricultural work that crosses into domestic extensions. Larch cladding — either sawn or planed — runs £75–£100/m² supply and fit. Western red cedar, which is naturally durable and often left to silver, sits at £90–£120/m². All timber cladding requires a counter-batten and batten system (25mm x 50mm counter-batten, 50mm x 25mm horizontal batten) to create a ventilated cavity — typically adding £8–£12/m² to the installed cost if not already included. Timber cladding is popular in conservation areas and new-build self-builds where it can sit within permitted development, but it demands quality fixings (stainless steel throughout) and correct detailing at base, top, and window reveals to avoid premature failure.

Composite / uPVC Cladding — £50–£100/m²

uPVC cladding boards (shiplap or weatherboard profile) are at the budget end: £50–£65/m² supply and fit. Wood-effect composite boards (PVC-ASA or aluminium composite) typically run £70–£100/m². Both fix directly to a timber batten system without the moisture management concerns of real timber. uPVC is popular on coastal properties and where low maintenance is the primary brief. Margins on uPVC can be squeezed by homeowners pricing materials online, so be specific in your spec — board thickness, manufacturer, and finish — to avoid being compared to inferior products.

Fibre Cement (HardiePlank, Cedral) — £70–£130/m²

James Hardie HardiePlank and Cedral (Eternit) are the dominant UK brands. Both are cement-based boards that are non-combustible, dimensionally stable, and carry a 15–30 year warranty. HardiePlank in a pre-primed smooth finish supply and fit runs £70–£95/m²; factory-coloured Cedral Click or Lap sits at £90–£130/m² depending on colour specification. Fibre cement is increasingly specified on new-build residential and retrofit projects precisely because it sits within the combustible materials restrictions — it's classified as A2-s1, d0 under BS EN 13501-1. Labour is slightly slower than uPVC due to board weight and the need for carbide blades, so factor that into your day rate calculation.

Brick Slip Cladding — £100–£200/m²

Brick slip systems (thin brick veneers bonded or mechanically fixed to a carrier panel) are the premium end of the affordable cladding market. Panel systems like Eurobrick or K-Rend brick slip sit at £100–£140/m² supply and fit. Individual hand-applied slip systems with hand-pointed joints run £140–£200/m² because of the intensive labour. The result is indistinguishable from full-thickness brickwork at a fraction of the structural load — popular on building extensions that need to match existing brick, and on commercial shopfront and residential flat elevations. Corners are the cost trap: pre-formed corner slips add £35–£60 per linear metre and every reveal multiplies corner count.

Metal Cladding (Zinc, Aluminium) — £120–£250/m²

Standing seam zinc is the prestige option: £180–£250/m² supply and fit, driven by material cost (zinc sheet at £60–£90/m² alone), specialist labour, and the need for a continuous substrate board. Pre-weathered zinc (Anthra Zinc, RHEINZINK graphite-grey) adds a further premium. Aluminium composite panels (ACM) in cassette or rainscreen systems run £120–£180/m² — though post-Grenfell procurement on buildings above 11m now requires A1 or A2-rated ACM specifically (see fire safety section below). For domestic extensions and small commercial projects under 11m, standard powder-coated aluminium panels remain a practical mid-range option. Always price metal cladding on a per-project basis after a site survey — the substrate, structural fixings, and corner/junction details vary significantly.

Typical Project Sizes

Before you can price per m², you need to establish the actual clad area. Most homeowners underestimate it. Use these as your starting benchmarks:

• Semi-detached (3-bed): 80–100m² clad area — typically front, gable, and rear elevations minus window and door openings. Allow 90m² as a working average.
• 3-bed detached: 120–150m² clad area. Four elevations with larger floor plate — allow 135m² as a working average.
• Single-storey extension: 30–60m² depending on footprint and whether side returns are included.
• Commercial unit / light industrial bay: 200–500m² — moves into a different pricing bracket with volume discounts on materials.

Always measure on site before quoting. Elevations with bay windows, conservatories, or complex rooflines can add 15–20% to your measured area versus a basic box calculation. Photograph every elevation and note existing substrate type (brick, block, timber frame, ICF) on your survey sheet.

What Drives the Cost Up

The m² rate is only the start. These are the variables that cause quotes to diverge by 30–50% on otherwise identical properties:

Substrate Condition

Spalling brick, blown render patches, or damp ingress all need addressing before cladding goes on. Substrate preparation — hack off, rebond, repoint — typically adds £8–£25/m² to your quote depending on severity. Always include a substrate report as part of your survey findings and price it as a provisional sum if condition is unknown until stripping begins.

Battening and Rainscreen Cavity

Timber and most board cladding systems require a ventilated rainscreen cavity — typically 25mm minimum. Counter-batten and batten systems in treated softwood add £10–£18/m² to your installed cost. On timber frame buildings with a breather membrane, you may also need to strip and replace damaged membrane before battening — add £5–£10/m² for membrane replacement.

Thermal Insulation Layer

If the project spec includes a thermal upgrade — EPS, mineral wool slab, or PIR board between the substrate and cladding — this typically adds £25–£55/m² for the insulation board and mechanical fixings, on top of the cladding cost. A full EWI (External Wall Insulation) system with render finish sits at £100–£180/m² all-in (see EWI section below).

Corners, Reveals, and Junctions

Corners and window reveals are where cladding labour time stacks up fast. Budget 2–3x the m² rate for linear metres of corner detail depending on system. A property with eight window openings, a door canopy, and four external corners can add 25–35% to your raw m² labour cost. Specify junction trims, starter beads, and movement joints in your quote — they protect your margin and give the client a clear scope.

Scaffolding — The Biggest Variable After Materials

Scaffolding is consistently the cost item that surprises homeowners and catches out contractors who forget to include it clearly. UK scaffold hire for a standard domestic property in 2026 typically runs:

• Small terraced / semi (single elevation, 2 storeys): £800–£1,200 erected, hired for 2 weeks, struck.
• Full semi-detached (3 elevations, 2 storeys): £1,400–£2,000.
• 3-bed detached (4 elevations, 2 storeys): £1,800–£2,500.
• Extended hire (beyond 2 weeks): £80–£150/week additional hire charge.

Always get scaffold pricing from your regular scaffolder before quoting, not from a standard rate card — tight access, overhead cables, and soft ground can all push costs up. Quote scaffold as a clearly separated line item so that clients understand it is a fixed overhead and not inflated as part of your margin.

If you are doing multiple elevation jobs, explore whether a full perimeter scaffold (more expensive up front) saves re-erection costs across multiple phases — on a detached property it often does.

EWI — External Wall Insulation Combined System (£100–£180/m² All-In)

A full EWI system — insulation board mechanically fixed and adhesive-bonded to the external wall, mesh-reinforced basecoat, and a render or brick slip finish coat — sits at £100–£180/m² for the complete installed system. The range reflects:

• EPS (expanded polystyrene) with render finish: £100–£130/m²
• Mineral wool slab with render finish: £120–£155/m² (mineral wool is non-combustible — important for taller buildings)
• EPS or mineral wool with brick slip finish: £145–£180/m²

EWI work on a standard semi (90m²) therefore runs from £9,000 to £16,200 supply and fit, plus scaffold. These are substantial projects with high material handling requirements and a real skill premium.

ECO4 and Great British Insulation Scheme Funding

If your client is in a lower EPC-rated property (D, E, F, or G rated) and meets the household income or benefits criteria, external wall insulation can be fully or partially funded under ECO4 (Energy Company Obligation 4) or the Great British Insulation Scheme (GBIS). As an EWI contractor, you can work with energy companies as an approved installer — check the Ofgem TrustMark and PAS 2030/2035 certification requirements before tendering for funded work. Funded EWI jobs are higher administration but generate larger project values and a repeatable referral pipeline.

Planning Considerations

Most external cladding on a domestic property falls within permitted development — you can change the material and colour of external walls without planning consent, provided the property is not in a designated area. However, the following situations require full planning permission:

• Conservation areas: Any change to the external appearance of a dwelling requires consent. This includes render over brick, timber cladding panels, or a change of colour. Article 4 Directions in many conservation areas explicitly remove PD rights for cladding.
• Listed buildings: Listed building consent is required for all external alterations. The type of cladding, fixing method, and detailing will all be scrutinised. Historic England guidance applies.
• National Parks and AONBs: PD rights are more restricted — check with the relevant authority before starting work.
• Flats and apartments: External works to flats require planning consent even outside designated areas.

Advise clients to check permitted development status with their local planning authority before work starts. Pre-application enquiries cost £30–£150 depending on the council and give a definitive answer quickly. If you are regularly working in conservation areas, build a relationship with one or two planning consultants who can advise on applications — it differentiates your offering from contractors who skip this step.

Fire Safety Regulations — What Cladding Contractors Must Know Post-Grenfell

The 2017 Grenfell Tower fire fundamentally changed the regulatory landscape for external wall systems in the UK. Key regulations that affect your cladding work:

The 11m Threshold

The Building Regulations (Amendment) (England) Regulations 2018 — commonly known as the combustible materials ban — prohibits the use of combustible materials in the external walls of buildings over 11m in height (roughly 4 storeys). This applies to all buildings with a storey at height above 11m, including residential dwellings, hotels, and student accommodation. For affected buildings, only materials achieving A1 or A2-s1, d0 classification under BS EN 13501-1 can be used in the cladding system — this includes insulation, boards, fixings, and breather membranes.

ACM Cladding and BR 135

Aluminium composite material (ACM) panels with a polyethylene core — the type used at Grenfell — are now prohibited on all residential buildings above 11m. If you are tendering for refurbishment work on existing buildings, check whether the existing cladding is ACM and what category it falls under (Category 1 = PE core, Category 2 = FR/limited combustibility core, Category 3 = non-combustible core). Only Category 3 ACM is compliant on affected buildings. BR 135 (BRE Fire Performance of External Thermal Insulation for Walls of Multistorey Buildings) sets out the testing methodology for external wall systems — any system used on a higher-risk building must be tested to this standard.

Domestic Extensions and Low-Rise Work

For the vast majority of domestic cladding work — single-storey extensions, 2–3 storey houses — the combustible materials ban does not directly apply (buildings are under 11m). However, standard building regulations still require that external walls contribute to adequate fire spread resistance. Part B (Fire Safety) of the Building Regulations requires that external wall surfaces achieve a minimum of Class C-s3, d2 rating (or better) where the wall is less than 1m from a boundary. For walls within 1m of a boundary, Class B or better is required. Discuss this with building control when submitting your building notice or full plans application.

EWS1 Forms and Mortgage Impact

If you are working on blocks of flats, be aware that lenders now require an EWS1 (External Wall System) form before issuing a mortgage. Completing EWI or cladding work without documented compliance can create problems for flat owners trying to sell. Always retain your system test evidence, installation records, and product data sheets — they will be needed if an EWS1 assessment is ever carried out on the building.

Labour Rates for Cladding Work

UK cladding and render fitter day rates in 2026:

A 2-man render or cladding crew can cover 60–100m² per day on straightforward open elevations with a monocouche or board product. That rate drops to 30–50m² when working around lots of windows, corners, and reveals. Use the lower figure when pricing — you'll rarely lose time on open elevations, but complex junctions always take longer than expected.

How to Structure a Cladding Quote

A professional cladding quote does three things: it gives the client a clear price, it protects you from scope creep, and it justifies your rate. Structure it like this:

1. Survey visit and substrate report — Charge for this separately (£150–£300) or build it into a paid pre-contract service. Document the substrate type on each elevation, photograph any defects, note access constraints and nearest scaffold drop point.
2. Measured m² area by elevation — Break down the quote by north, south, east, west elevation. Include a deduction schedule for window and door openings. This protects you if any elevation is removed from scope later.
3. Materials specification — Name the manufacturer, product code, and colour reference. A quote that says "render finish" loses to one that says "Weber Pral M in Cornish Cream, 15mm two-coat system with 6mm grey mesh reinforcement over all movement joints." The specificity wins trust.
4. Scaffold — included or separate — Be explicit. If you are arranging scaffold, include it as a named line item with the scaffolding company name. If the client is arranging their own scaffold, state the access requirement clearly. Never leave this ambiguous.
5. Provisional sums for substrate repair — If you cannot fully assess substrate condition from a visual survey, include a provisional sum (typically £500–£1,500) and specify the trigger conditions that would draw on it. This is far better than a variation claim mid-project.
6. Exclusions — List what is not included: UPVC window replacements, soffit and fascia replacement, any electrical works, planning applications. Clients assume a lot is in scope if you do not explicitly exclude it.

Send the quote as a PDF with your company logo, registration number, and insurance details. A cladding project at £8,000–£25,000 is a significant domestic purchase — the professionalism of your quote document directly affects your win rate.

Profit Margin on Cladding Materials

A 15–25% margin on materials is the standard expectation for cladding and render work. On a £6,000 materials job, that is £900–£1,500 of gross margin from the materials element alone, on top of your labour rate. Do not undercut this to win work — cladding materials require significant handling, storage, and sometimes wastage that is not reflected in the net trade price.

On EWI and larger render systems, you may be able to negotiate 30–35% trade discount from merchants on high-volume orders. Protect that margin — it is the reward for your buying power and your account management with the merchant.

Be particularly careful on metal cladding projects where material costs are high. A zinc or aluminium panel order at £15,000 trade is not the same risk profile as £1,500 of uPVC boards. Stage your payment terms to match your material expenditure: ask for a deposit to cover materials before ordering, with the balance on practical completion.

Know Which Marketing Channels Win Your Cladding Enquiries

Cladding jobs — particularly EWI, brick slip, and metal cladding — sit at the high-value end of the residential and light commercial market. A single clad elevation on a detached house might be a £12,000–£22,000 project. At that value, knowing where the enquiry came from is not optional — it determines where you invest your marketing budget.

Most cladding contractors find their best leads come from one of three sources: Google Search (homeowners researching render or cladding types), Checkatrade or Rated People (homeowners looking for local approved contractors), or direct referrals from architects, builders, and previous clients. The trouble is, without proper attribution tracking, you assume the sources that feel busy are the ones that convert — and often you are wrong. A contractor spending £300/month on Checkatrade and £200/month on Google Ads may find that 80% of their completed cladding jobs came from a handful of referrals they never recorded properly.

Trade2Base tracks every inbound enquiry — from phone call to website form to WhatsApp message — and attributes it to the source: Google Ads, Checkatrade, Google Business Profile, referral, or direct. For high-value cladding work, this lets you double down on the channels that bring projects at the margin you want, and stop paying for the ones that bring price-shoppers and tire-kickers.
