Summary
A kitchen splashback is the cheapest single upgrade that visually finishes the kitchen — and it's also the most variable in price across the trade. The customer sees "a bit of glass behind the cooker" and assumes it's a half-day job. The supplier sees a templated tempered-glass panel with edge polishing, two socket cutouts, two-part silicone fix, and a £900 invoice. Both are usually right; what varies is the material, the spec, and the trade's experience pricing it.
This article splits the market into four common splashback types — coloured glass, tile, stainless steel, and solid surface/stone — and gives the cost logic for each. Glass and stone are templated and supplied to site; tile and stainless steel are usually cut and fitted on site. The labour profile differs accordingly: glass is fast to fit but slow to procure; tile is the opposite.
Two regulatory points drive the technical specification: Approved Document J's requirements on materials around heat-generating appliances, and the appliance manufacturer's installation manual (which usually specifies minimum clearances to combustible surfaces, especially for gas). A glass splashback rated for cooker use is fine; a sheet of acrylic or unrated MDF panel is not.

Detailed Guidance
Compliance: What Sits Behind the Hob
Approved Document J sets the requirements for surrounding surfaces near combustion appliances, and the appliance manufacturer's installation manual sets specific minimum clearances. For a gas hob:
- Typical minimum clearance from hob top to underside of wall units: 760mm
- Adjacent combustible material (wall units, cabinetry): minimum side clearance per manual (usually 50–75mm)
- Splashback material directly behind hob: must be non-combustible OR meet the manufacturer's specified material requirements
For most splashback materials (glass, ceramic tile, stainless steel, stone, solid surface) the answer is "compliant". For materials such as acrylic, vinyl wall panel, or unrated MDF cladding marketed as "splashback panel", the answer is "not compliant" — these can melt, deform, or ignite from sustained hob heat. Refuse to fit these directly behind a hob even if the customer asks.
Glass Splashbacks
The most popular premium splashback in modern UK kitchens. Tempered (toughened) safety glass per BS EN 12150, 6mm minimum thickness, with a back-painted colour layer (the colour is on the rear face, viewed through the glass). Modern manufacturers offer paint-matched RAL/Pantone colours, plus printed designs.
Process:
- Site survey: measure the wall area, identify all socket/switch positions, hob position, ventilation cutouts
- Customer signs off the design (colour, layout, cutout schedule, any features such as polished edges)
- Template (digital or paper) sent to factory
- Factory cuts to size, water-jets cutouts, paints back, tempers (sequence varies by manufacturer)
- Delivery to site (7–14 days)
- Fit: clean substrate, dry-fit, apply two-part epoxy or specialist silicone in dots/strips on the rear, position glass, hold with timber wedges for 24 hours
- Edge silicone at all joints (mould-resistant)
Typical pricing:
- Single 600 × 750mm hob-back panel, one colour, one socket cutout: £250–£400 supply, £350–£600 total
- 3-metre run, two cutouts: £600–£1,000 supply, £800–£1,400 total
- Printed/photographic glass: 50–100% more
Common errors:
- Templating against an unfinished wall (lath plaster, missing socket boxes); the panel arrives and the wall has moved
- Specifying a cutout in the wrong position (socket relocated post-template)
- Pressing too hard on the glass when bedding; cracks appear days later
- Using ordinary silicone instead of glass-safe (some standard silicones lift paint off the back of glass over months)
Tile Splashbacks
The traditional UK splashback. Costs vary by tile (metro tiles £20/m² up to natural stone £150+/m²), but the labour scales with tile size — small mosaics and detailed patterns take 3–4× the time of large-format tiles.
Process:
- Substrate check: plasterboard, plaster, or existing tile. Plasterboard requires PVA primer + flexible tile adhesive
- Set out: identify cut points (ideally not in the middle of the visible area)
- Adhesive: cement-based to BS EN 12004, flexible for plasterboard
- Cut: wet diamond saw on site; dust extraction if internal
- Grout: cement or epoxy per spec; sponge clean before grout fully cures
- Silicone perimeter: mould-resistant; never grout the worktop/wall joint (it cracks with movement)
Pricing logic:
- Tile per m²: £20–£200 supply (huge range)
- Labour per m²: £80–£180 (large format low end; mosaic, hexagonal, detailed pattern high end)
- Adhesive, grout, sealant: £15–£40 per m²
- Setup/strip: £80–£150 per job
- Cutouts handled in labour
A 3m² metro tile splashback might be £350–£600 supply and fit; the same area in a marble herringbone could be £800–£1,400.
Stainless Steel
A practical choice in busy kitchens and rental units — heat-tolerant, easy to clean, no joints to fail.
Process:
- Template: measure on site, including cutouts and edge details
- Fabricate: cut to size, deburred edges, brushed or polished finish
- Fit: epoxy adhesive or screw-fix into pre-drilled holes (screws through grommets, capped)
- Silicone perimeter
Hidden costs: stainless does mark with cutlery scratches and water spots; brushed finish hides this better than polished. Recommend a single sheet rather than panels with visible joints. Magnetic stainless (grade 430) is available cheaper but scratches more obviously than grade 304.
Solid Surface / Stone
Specified where the customer wants the splashback to match the worktop (e.g. continuous Corian or quartz from worktop to underside of wall units). This is templated and fitted by the worktop specialist, usually as part of the same visit.
Material cost is the same per m² as the matching worktop; install labour is lower because the substrate is straightforward (vertical wall, no cutouts where possible, joins to the worktop directly). The premium is mostly material.
Substrate Preparation
The substrate determines what works:
- Fresh plaster — Must be fully dry (3–6 weeks for skim plaster) before glass, mist coat first; tiles can go on sooner with flexible adhesive
- Existing tile — Glass can go directly over (cleaned, primed); new tiles can go over old with appropriate primer + flexible adhesive (adds significant weight)
- Plasterboard — All materials acceptable with appropriate adhesive
- Render — Glass OK with appropriate primer; tile OK with cement adhesive
- Painted plaster — Always check adhesion; strip if peeling; cross-hatch test before glass fit
Skipping substrate prep is the most common source of failures 3–12 months post-install: glass falls off; tiles drum-sound and crack; sockets pull away from the wall.
Worked Example: Hob-Area Glass + Subway Tile Wall
Job: Modern kitchen with painted toughened-glass back-of-hob panel (single 900 × 700mm, two cutouts for cooker hood control and socket), and the rest of the back wall (3.6m × 600mm) tiled with white metro tiles in stack-bond layout.
| Item | Cost |
|---|---|
| Toughened glass panel (custom colour, polished edges, 2 cutouts) | £380 |
| Metro tiles (3 boxes white gloss 100×200mm, 90 tiles incl. waste) | £75 |
| Tile adhesive + grout + sealant | £55 |
| Silicone, primer, fixings | £25 |
| Materials subtotal | £535 |
| Glass templating visit | £100 |
| Glass fit (incl. wedging, 24hr return) | £180 |
| Tile labour (2.2m² × £120/m²) | £264 |
| Substrate prep | £80 |
| Setup, clean, hand-over | £80 |
| Labour subtotal | £704 |
| Subtotal | £1,239 |
| Markup 20% | £248 |
| Net price | £1,487 |
| VAT 20% (if registered) | £297 |
| Customer price (VAT-reg) | £1,784 |
A typical customer perception is "splashback is £400–£600" — but they're thinking of one component (the glass or the tile) and not the whole job. Itemising the quote stops the inevitable "why is it so much" conversation before it starts.
Frequently Asked Questions
Can I use acrylic splashback panels behind a gas hob?
No. Acrylic and similar polymer-based splashback panels do not meet Approved Document J requirements for non-combustible material near a gas hob, and the hob manufacturer's installation manual typically prohibits them. Use them away from the hob (e.g. behind a microwave on a non-cooking wall) only.
What thickness of glass do I need for a splashback?
6mm tempered (toughened) is the standard for splashbacks. 4mm is too thin for cantilevered cuts around sockets; 10mm is over-spec and increases material cost without benefit. The glass must be tempered (BS EN 12150) — annealed glass is unsafe in a kitchen and will not survive thermal cycling near a hob.
How long after plaster can I fit a glass splashback?
3–6 weeks for fresh skim plaster (the colour change from grey to pink indicates initial drying but not full cure; full moisture release takes weeks). Apply a mist coat (50:50 emulsion/water) before fitting glass — the glass back-paint can react to alkaline plaster and the panel will lift over time without it.
Can I tile over existing tiles?
Yes, with substrate prep (sand, clean, prime), flexible adhesive, and a check that the wall behind the existing tiles can take the additional weight (plasterboard with old tiles can rip out under the second layer's weight if the original fixings were marginal). For glass, fitting over existing tile is straightforward and often the simplest solution where stripping old tiles would damage the wall.
Who is responsible for ensuring socket positions match the cutouts?
The fitter takes responsibility for confirming socket positions before templating, and the customer signs off on the cutout schedule. Once the glass is cut and delivered, a socket relocation costs the customer the price of a new panel (£250–£500+). Be explicit at template time: "if you want to move the socket, tell me now, not after delivery."
