Is my garden landscaping quote fair? What UK homeowners should expect

Garden landscaping quotes vary more than almost any other domestic trade. Two quotes for "the same garden" can land £15,000 apart because one includes a porcelain patio over a 150mm MOT Type 1 sub-base and the other prices concrete slabs on a bed of sharp sand. Both are technically landscaping. They are not the same job.

This guide is a checklist for telling them apart. For ranges by scope, start with the garden landscaping cost guide. For the general method, see how to compare builder quotes.

Typical price, so you have a benchmark#

In 2026, UK garden landscaping ranges by scope. A small refresh is roughly £1,200 to £2,500. A mid-sized project (patio plus fencing, turf, or planting) runs £2,500 to £10,000. A full redesign typically sits at £10,000 to £12,500, and larger or premium projects with retaining walls, drainage works, lighting, or a garden room go £12,500 to £20,000 and above. A patio supplied and laid is typically £100 to £150 per m² for standard work.

If your quote sits well outside the band for your scope, that is the first question to raise. The answer is often "this is hard landscaping only, no planting", or "the sub-base is heavier because the site is clay", both of which are useful answers.

The materials gap#

Landscaping has one of the widest material price ranges of any trade. The same area of patio can vary by 5x in materials alone, before any labour:

• Paving: concrete slabs are roughly £20 to £35 per m². Indian sandstone is £35 to £65. Porcelain is £55 to £100. Granite and Yorkstone are £80 to £150 and above. A 30m² patio is £600 in concrete or £4,500 in porcelain before laying.
• Fencing: feather-edge on softwood posts is £30 to £45 per metre installed. Closeboard on concrete posts with gravel boards is £50 to £80. Composite is £100 to £180.
• Turf: standard cultivated turf is £4 to £7 per m² supplied. Specialist blends (shade-tolerant, fine fescue) sit at £10 and above.
• Decking: pressure-treated softwood is £30 to £60 per m² in materials. Composite is £80 to £150.

A line that reads "patio, £3,500" with no material is not a price. It is a placeholder. The same goes for "fence, £1,200" with no panel type, post material, or height.

What a fair landscaping quote should itemise#

A reasonable landscaping quote breaks the price into at least these lines, with a number against each:

• Site clearance: removal of turf, slabs, old fencing, vegetation, debris. Skip cost or grab-lorry hire stated.
• Excavation and groundworks: depth in millimetres, area in m², spoil volume in tonnes or cubic metres. Critical on sloping or clay sites.
• Sub-base: material (usually MOT Type 1), depth (75 to 150mm for patios, 100 to 200mm for driveways), and whether it is compacted in layers.
• Edge restraints: kerbs, haunching, or concrete edging, with materials.
• Hard landscaping: paving spec (brand, type, finish, thickness, m²), fence panels (brand, height, material, linear metres), decking (composite brand or timber grade, m²).
• Bedding and jointing: mortar bed thickness for paving, jointing method (resin compound, brush-in sand, wet mortar pointing).
• Drainage: surface-water falls, linear drains, soakaways. Required by Building Regs Part H on most new hard surfaces where water cannot soak away naturally.
• Soft landscaping: turfing area, topsoil depth (typically 100 to 150mm for new lawns), planting schedule with plant names and pot sizes.
• Sundries: weed membrane, mortar, sand, jointing compound, fixings.
• Labour: day rate or fixed price, broken out by stage where useful.

A lump sum "Landscape rear garden, £14,000" with no sub-base depth, no paving spec, and no fence material is the most common pattern worth pushing back on. For the general format, see how to read a builder's quote.

What is typically excluded#

Items that often quietly fall outside the headline price:

• Tree work: felling, stump grinding, root barriers. Usually a separate arboriculturist quote.
• Garden electrical: lighting circuits, outdoor sockets, EV-ready cabling. Part P-notifiable and needs a registered electrician.
• Outdoor water: garden taps, irrigation hookups, hose bib relocation. Often left as "by others".
• Planning permission and Building Regs: boundary fences over 2m, garden buildings outside permitted-development limits, raising ground levels near a boundary, work affecting protected trees. Some need permission, some need Building Regs sign-off.
• Mains drainage connection: where surface water cannot soak away on site, connecting to a foul or surface-water sewer can add £1,000 to £3,000.
• Skip permits: needed if the skip sits on a public road, typically £30 to £100 per week from the council.
• Imported topsoil: poor existing soil can need an extra 50 to 150mm of imported topsoil, adding £500 to £1,500 on an average garden.

For the broader pattern, see hidden costs in builder quotes.

Red flags specific to landscaping#

• No sub-base depth or material. A patio laid on a thin sand bed without a properly compacted MOT Type 1 sub-base will lift, crack, or pond water within two winters. If the depth in mm is not on the quote, it is not being priced.
• Paving material absent. "30m² patio, £4,500" tells you nothing without the slab spec. The same area is £600 in materials at the low end and £4,500 at the high end.
• Hard surface over 5m² with no drainage detail. Building Regs Part H applies to most new hard surfaces. A flat patio with no fall stated and no soakaway is being designed badly, and the water will go somewhere it shouldn't.
• Fence over 2m with no planning note. Boundary fences over 2m generally need permission (1m next to a highway). A quote that does not flag this leaves the homeowner exposed if the council asks for it to come down.
• Garden building close to a boundary, with no permitted-development check. Outbuildings over 2.5m in eaves height, or within 2m of a boundary at over 2.5m total height, trip permitted-development limits. Worth flagging.
• Garden lighting or sockets with no electrician named. New outdoor circuits are Part P-notifiable. The electrician's qualifications should be on the quote.
• Excavation priced as a single lump on a sloping or clay site. Spoil volume drives skip and grab-lorry cost. A flat number with no tonnage or cubic metres is the line that overruns most often.

Before you sign#

1. Is hard landscaping itemised by material, area, and thickness?
2. Is the sub-base depth and material on the quote?
3. Are fencing panels and posts specified by material and height?
4. Is drainage in scope, or excluded in writing?
5. Is any electrical work allocated to a Part P-registered electrician?
6. Are planning permissions flagged for fence heights, garden buildings, or boundary changes?
7. Is the total in the typical band for your scope and region?

If three or more are unclear, the quote is not ready to compare against another. Get the missing items in writing before deciding.

The shortcut#

Working through this by hand means knowing material rates per m², sub-base specifications, fence and decking grades, and what triggers Part P or planning.
