Brick Slip Costs UK — What to Charge for Supplying and Fitting Brick Slips in 2026

What Are Brick Slips and Where Are They Used?

A brick slip is a thin slice of brick — typically 15–25mm thick — bonded to a wall to give the appearance of a full brick course without the weight, depth or foundations of conventional brickwork. Because they are essentially a tile, they can be applied to almost any sound, flat substrate, indoors or out.

The most common applications you'll be asked to quote are:

• Interior feature walls: living rooms, hallways, chimney breasts and media walls where a brick or exposed-industrial look is wanted.
• Exterior facades: cladding to extensions, garden rooms and full elevations on timber-frame or block-built properties.
• EWI and render systems: slips fitted over external wall insulation so an insulated property keeps a brick appearance rather than a flat render finish.
• Fireplaces and chimney breasts: reclaimed or weathered slips for a period look around a stove or open fire.
• Kitchen splashbacks and bars: small-area feature work that often commands a premium per m² because of the cutting and detailing involved.

Because the same product covers everything from a 2m² splashback to a full house elevation, pricing varies enormously. The job type, access and amount of detailing matter far more than the raw cost of the slips.

Types of Brick Slip and What They Cost to Buy

The slip itself is only part of your material cost — you also need corner pieces, adhesive and pointing mortar. But the type of slip sets the base price and influences how long the job takes, so it's where quoting starts.

Clay / Kiln-Fired Slips

Cut or extruded from real fired clay, these are the most authentic option and the standard choice for exterior work because they are frost-resistant and colour-stable. They are sold by the m² or in box quantities, and a huge range of colours and textures is available to match almost any existing brickwork.

• Standard clay slips: £35–£65/m² supply
• Premium / handmade / blend-matched ranges: £60–£90/m² supply

Concrete / Cast Slips

Concrete slips are cast from a cement mix rather than fired clay. They are usually the cheapest option and can be a good fit for budget-conscious interior work or where a specific moulded texture is wanted. Quality varies — cheaper concrete slips can look uniform and "cast" up close, so they suit feature walls more than full elevations.

• Concrete slips: £30–£50/m² supply

Reclaimed Slips

Cut from genuine reclaimed bricks, these give an instant weathered, period character that new slips struggle to replicate. They are popular for fireplaces, barn conversions and heritage extensions. Expect more variation in size and thickness, which slows fitting and increases waste — build that into your labour estimate.

• Reclaimed slips: £45–£80/m² supply (and rising for sought-after stocks)

Flexible / Brick-Effect Slips

Flexible slips are made from a polymer-modified material that bends around curves and is very light. They are quick to fit and forgiving on uneven substrates, but they are not real brick and won't convince at close range or on a primary elevation. They suit curved features, interior accent areas and quick-turnaround commercial fit-outs.

• Flexible / brick-effect slips: £25–£45/m² supply

Corner Pieces (L-Shaped Returns)

Wherever the slip wraps around an external corner — a window reveal, a door opening, the corner of an elevation — you need an L-shaped corner piece so the joint looks like a real brick return rather than two slips butted together. Corners are sold individually or by the linear metre and are significantly dearer than flat slips. A job with lots of openings can have a corner bill that rivals the flat-slip cost.

• Clay corner pieces: £3–£6 each (roughly £40–£70 per linear metre)

Adhesive, Pointing and Sundries

Two consumables make a real difference to your material cost and are easy to forget when quoting from the slip price alone:

• Adhesive: a flexible, weatherproof, cementitious tile/slip adhesive (often a rapid-set or frost-resistant grade for exterior work). Budget around £5–£10/m² in adhesive depending on substrate flatness and the notch size needed.
• Pointing / jointing mortar: a dry mortar gun-pointed or slurry-pointed into the joints, available in a range of colours to match the bond. Budget around £5–£12/m².
• Primer, mesh, beads and fixings: on EWI and some board substrates you also need a primer or a mechanically-fixed mesh/lath system, which can add £8–£20/m².

Add it up and the total material cost for a straightforward clay-slip job often lands around £45–£90/m² once adhesive and pointing are included — before any labour. Pricing off the bare slip cost is the single most common way installers lose money on these jobs.

The Fitting Process

Knowing the sequence helps you estimate labour honestly. A typical brick slip installation runs through three stages.

1. Substrate Preparation

The wall must be sound, flat and able to carry the weight. Plaster may need to come off back to a stable background, blockwork may need priming, and EWI requires its proprietary base coat and mesh. Out-of-true walls have to be made good or the slips will telegraph every hump and hollow. Prep is where unexpected time gets eaten — survey the substrate before you price.

2. Adhesive / Mechanical Fixing

Slips are bedded into a notched adhesive, usually working off a set-out line and spacers (or a setting-out batten) to keep courses level and joints consistent. On taller exterior elevations a mechanical fixing system — a rail or mesh that the slips key into — may be specified for added safety and to satisfy warranty or building-control requirements. Corners go on first so the returns line through with the field courses.

3. Pointing / Grouting

Once the adhesive has cured, the joints are pointed — either gun-applied and tooled, or slurry-pointed and brushed back. The pointing finish (flush, bucket-handle, recessed, weather-struck) changes both the look and the labour time. A deep recessed joint with a struck finish takes noticeably longer than a flush slurry point and should be priced accordingly.

Typical Fitted Prices UK 2026

Most installers quote brick slips as a fitted rate per m² (supply and fit) and add access and corner detailing separately. As a guide for 2026:

• Interior feature wall, good flat substrate: £70–£110/m² fitted
• Exterior elevation, standard access: £90–£140/m² fitted
• EWI overclad or complex / high-detail work: £120–£180+/m² fitted

Labour on a feature wall typically runs £40–£70/m² on top of materials; exterior and EWI work carries more because of access, weatherproofing detail and the mechanical-fixing element. Small jobs (a splashback or a single chimney breast) should carry a minimum day-rate charge — the set-up, cutting and pointing don't scale down neatly, so a 2m² splashback can still be a full day's work.

Worked Example: Interior Feature Wall

A living-room chimney breast and return, 6m² of clay slips with two external corners, fitted onto a freshly skimmed and primed wall.

• Clay slips, 6m² at £50/m²: £300
• Corner pieces (approx 5 linear metres at £55/m): £275
• Adhesive + pointing mortar: £90
• Labour (approx 2 days, set-out, fit, point): £500–£700

Total in the region of £1,165–£1,365, which works out around £195–£230/m² on a small area — a good illustration of why per-m² rates rise sharply on tiny, detail-heavy jobs. Quote a small feature wall as a package, not a bare rate, or you'll undercharge.

Worked Example: Exterior Elevation

A two-storey rear extension elevation, 40m² of clay slips over a primed and meshed blockwork wall, with scaffold access and window/door reveals.

• Clay slips, 40m² at £50/m²: £2,000
• Corner pieces around reveals (approx 30 linear metres at £55/m): £1,650
• Adhesive, pointing, primer/mesh: £900
• Labour (fit and point, 40m²): £2,200–£3,200
• Scaffolding: £800–£1,500

Total in the region of £7,550–£9,250, or roughly £190–£230/m² all-in once scaffold and corners are included. Note how much of the cost sits in corners and access rather than the field slips — that's the pattern on almost every exterior job with openings.

What Drives the Cost Up

Two jobs of the same m² can differ by 50% or more on price. The main cost drivers are:

• Area: larger continuous areas are more efficient per m²; small or fiddly areas carry a minimum-charge premium.
• Corners and openings: every external corner needs a corner piece and careful setting-out. A wall full of windows costs far more than a blank elevation of the same size.
• Height, access and scaffolding: ground-floor work off a hop-up is cheap; two-storey elevations need scaffold, which adds £800–£2,500 and slows the job.
• Substrate condition: a flat, sound, primed wall fits fast. An uneven, damp or unsuitable substrate needs making good first, adding both time and risk.
• Pointing finish: a recessed or weather-struck joint takes longer to tool than a flush slurry point — price the finish, not just the slips.
• Slip type: reclaimed and variable-size slips fit slower and waste more than uniform machine-cut clay.

Quoting Tips — What to Check Before You Price

Brick slip quotes go wrong when the installer prices off a customer's photo rather than a proper survey. Before you commit a price, check the following:

• Substrate type and condition: plaster, blockwork, board or EWI all need different prep and adhesive — confirm what you're fixing to.
• Flatness: hold a straight edge to the wall. Hollows and bows add making-good time and can ruin the finished look if ignored.
• Number of corners and openings: count them. Corner pieces and reveal detailing are often the biggest single cost on a job.
• Access: single or two-storey, scaffold or hop-up, and whether you can get materials to the wall easily.
• Exterior exposure: for outside work, confirm frost-resistant slips and weatherproof adhesive, and check any building-control or warranty requirement for mechanical fixing.
• Pointing colour and finish: agree these up front and note them in the quote — changing the joint finish after fitting is expensive.

Include a short set-out and material note with your quote. Even a one-page summary — substrate, slip type, corner count, pointing finish, access method — lifts your quote above competitors who just send a number, and protects you when the customer later asks why the corners cost so much.

Frequently Asked Questions

How long do brick slips last?

Properly fitted clay slips on a sound substrate last as long as conventional brickwork — decades — because the slip is real fired clay. The weak points are the adhesive bond and the pointing, so frost-resistant materials and good substrate prep matter most on exterior work. Concrete and flexible slips have a shorter realistic life and are better suited to interiors.

Are brick slips suitable for exterior walls?

Yes, provided you use frost-resistant clay slips, a weatherproof flexible adhesive, and the correct substrate or EWI base coat. On taller elevations check whether a mechanical fixing system is required by the manufacturer's warranty or building control. Avoid concrete and flexible slips for primary exterior elevations.

Can I fit brick slips over external wall insulation?

Yes — this is one of the fastest-growing uses. The slips are fixed to the EWI system's base coat and reinforcing mesh, often with a mechanically-fixed rail or mesh for slips on taller walls. Always follow the EWI manufacturer's specification, as fixing slips to the wrong base coat can void the system warranty.

Why are brick slips priced per m² but small jobs cost so much more?

Set-out, cutting, corner detailing and pointing don't scale down. A 2m² splashback still needs a setting-out line, neat cuts and tooled joints, so the per-m² rate on a tiny job can be double or triple a large elevation. Always apply a minimum charge to small areas.

Do I need corner pieces?

Anywhere the slip turns an external corner — reveals, openings, the corner of an elevation — yes. L-shaped corner pieces make the return read like a real brick rather than two slips butted together, and they're often the biggest single line on a detail-heavy quote, so count them carefully.
