Marble pricing is quoted a dozen different ways, which makes comparing quotes genuinely difficult. The stone itself is often less than half of what you pay, and the rest sits in fabrication, edge detail, cut-outs and fitting. Here is how the numbers actually break down for a London kitchen, and where the money tends to go.
For a supplied and fitted marble worktop in London, most kitchens land somewhere between £450 and £1,200 per square metre including fabrication and installation. A modest run of Carrara in a galley kitchen might come in around £2,500 to £4,000 all in. A larger kitchen with an island, a wide book-matched slab and mitred edges can pass £10,000 without anything unusual happening.
The spread is mostly slab choice. Bianco Carrara is the entry point because it is quarried in volume and the blocks are consistent. Calacatta, Statuario and Arabescato cost more per slab because the yield is lower and the veining is the point. Anything sold as a feature slab, where you are buying a specific piece for its pattern, is priced as a one-off.
Fabrication is skilled work and it is charged as such. A 20mm slab given a 40mm or 60mm mitred edge means cutting, bonding and polishing a return so the joint disappears, and that can add £80 to £150 per linear metre over a simple pencil round. Undermount sink cut-outs with polished internal edges, drainer grooves, hob cut-outs and tap holes are each priced individually, typically £80 to £250 depending on complexity.
Templating is a separate visit before anything is cut. A templater takes a digital profile of your units so the stone follows the real walls rather than the drawings, which in older London properties is rarely square. Expect that visit to be included in a proper quote, but check, because a few suppliers list it separately.
Access matters more in London than anywhere else. A slab is heavy and rigid, and getting one into a second-floor flat with a tight staircase or a lift that will not take the length can mean extra hands, a scaffold lift, or splitting the piece with a visible joint. Parking suspensions in controlled zones and congestion or ULEZ charges also find their way into the price, fairly or otherwise.
Quartz sits at a similar or slightly lower price point and is non-porous, so it does not etch. Sintered stone such as Dekton or Neolith costs more to fabricate because it is harder on tooling. Granite is usually cheaper than premium marble but the look is different.
The real cost question with marble is not the invoice, it is maintenance. Marble is calcium carbonate, so lemon juice, vinegar, wine and descaler will etch the polished surface into a dull mark. Sealing reduces staining but does not stop etching, and no sealant sold will. A honed finish disguises etching far better than a polished one, which is why we often steer clients towards honed for a working family kitchen.
If dull patches near the sink would bother you, budget for professional repolishing every few years, roughly £200 to £500 for a section, or choose a different material. Neither answer is wrong, but knowing your own tolerance before you commit saves a lot of regret.
Quotes vary wildly because they include different things. Ask every supplier to itemise, then compare like for like rather than the headline figure.
One more thing worth asking: whether you can view and reserve the actual slab. Marble varies block to block, and two slabs of the same named stone can look quite different. Most London stone yards in and around Park Royal and Hayes will let you walk the racks and tag the one you want.
Occasionally, but most fabricators charge more to work with client-supplied stone because they carry no warranty on breakage or hidden flaws. If a slab cracks during fabrication, you absorb the loss rather than the supplier.
Remnants can cut the slab cost by 30% to 50% and work well for small runs, a utility room or a vanity top. They rarely suit a full kitchen because you cannot guarantee matching veining across pieces.
Online figures usually quote bare slab cost per square metre before fabrication, edge work, cut-outs, delivery and fitting, and often before VAT. Once those are added, a realistic fitted price is commonly double the headline number.
