If you have been quoted wildly different prices for a garden wall, you are not imagining it. The cost per metre depends on height, thickness, foundations and the ground it sits on, which is why two walls of the same length can differ by hundreds of pounds. Here is how we price them as bricklayers working around Aberdare and the Cynon Valley, so you know what a fair quote looks like.
As a broad guide in 2026, a straightforward single-skin brick garden wall around 600mm to 1m high usually works out at roughly £150 to £250 per metre, including new foundations, materials and labour. A double-skin (215mm thick) wall, which you need for anything much above 1m or anything retaining soil, typically runs from about £250 to £450 per metre. Natural stone or a stone-faced wall, common in the Valleys where people want it to match older properties, can push towards £400 to £600 per metre.
These are ranges, not promises. A short run of wall often costs more per metre than a long one, because setting out, digging footings and bringing materials in carries a fixed cost whether you build three metres or thirty. Always ask for a fixed written quote for your specific job rather than relying on a per-metre figure alone.
Height and thickness matter most. Doubling the height of a wall more than doubles the cost, because a taller wall needs a thicker build, deeper footings and often piers every few metres to keep it stable. Brick choice matters too: a basic facing brick might be £450 to £600 per thousand, while handmade or reclaimed bricks to match an older terrace can cost two or three times that.
Ground conditions are the wildcard, and around the Cynon Valley they catch people out. Plenty of gardens here are on a slope, so a level wall may need stepped foundations, and anything holding back earth is a retaining wall, which is a different job entirely: it needs drainage behind it, stronger construction and sometimes engineering input. Access matters as well. If we can get a mixer and materials to the back of the house easily, you pay less than if everything has to be barrowed through a narrow terraced-house passage.
A garden wall is only as good as its footing. For most walls we dig a trench around 300mm to 450mm deep and fill with concrete, deeper on soft or made-up ground. If a quote seems suspiciously cheap, ask what depth of foundation is included, because skipping this is the main reason garden walls lean or crack within a few years, especially with the amount of rain South Wales gets.
Budget for the finishing details too. Coping stones or brick-on-edge tops protect the wall from water getting in and freezing, and they are not always itemised in quotes. Removing an old wall and carting away the rubble typically adds £40 to £80 per metre depending on skip costs and access. If the wall sits on a boundary, talk to your neighbour before work starts; it is cheaper than a dispute afterwards.
Most garden walls in Wales fall under permitted development, so you will not need planning permission if the wall is under 2m, or under 1m where it fronts a road. If your house is listed or in a conservation area, check with Rhondda Cynon Taf council first. Retaining walls over about 1m, or any wall an engineer would worry about, deserve a proper design rather than guesswork.
Time-wise, a typical 10m garden wall takes around three to five working days: a day or so for digging and concreting footings, then the build, then pointing and copings. Weather plays a part, as bricklaying stops in frost and heavy rain, so winter jobs can stretch a little longer.
For a single-skin brick wall about 1m high, expect somewhere in the region of £1,500 to £2,500 including foundations, with double-skin or stone versions costing more. Get an itemised fixed quote, as access and ground conditions shift the price.
Yes, usually by half or more upfront, but a well-built brick wall should last 50 years or longer with almost no maintenance, while a fence typically needs replacing every 10 to 15 years. Over its lifetime a wall often works out the better value.
Sometimes. If the old footing is sound, deep enough and wide enough for the new wall, reusing it can save a good chunk of the cost, but we always expose and check it first rather than assume, as building on a poor footing just moves the problem a few years down the road.
