How to Price Turf Laying and New Lawn Installation: Prep, Seeding vs Turf Comparison

Quick Answer: Turf laying in a typical UK domestic garden costs £18–£35 per m² supply-and-fit in 2026. A 50 m² lawn typically costs £900–£1,750 fitted, taking a 2-person crew 1–2 days. Turf itself is £4–£8/m² supply (premium fescue/ryegrass turf £8–£14); preparation labour (rotovate, level, rake) £15–£25/m². Seeding is cheaper at £6–£12/m² fitted but takes 12–16 weeks to establish vs 2–3 weeks for turf. No specific Building Regulations apply; SuDS rules apply where the lawn drains to a public sewer. BS 3936-1 covers nursery turf grades.

Summary

A new lawn — either by turf or seeding — is one of the most common landscaping requests on UK domestic refurb projects, especially after extensions, garden room builds, or removal of old paving and patios. The job sounds simple but skilled prep is what determines whether the lawn looks healthy and uniform within months or whether it goes patchy, weedy and uneven.

For a contractor pricing the work, the variables are existing surface (grass, soil, paving, hardcore), levels (new lawns often need re-grading to drain away from the house), edging, and supply quality. A simple 50 m² flat lawn over good topsoil is straightforward; a sloping site that needs grading, drainage, fresh topsoil and edging is significantly more expensive.

The turf-vs-seed decision is largely about timing. Turf gives an instant lawn that's walkable in 2–3 weeks. Seed costs roughly half but takes 3–4 months to establish, with a no-walk period of 8–12 weeks and ongoing weed management. Customers who want lawn for a summer event, paying customers, or have kids/dogs almost always go for turf. Seeding suits patient customers, larger areas, and slopes where turf laying is laborious.

Detailed Guidance

Turf Selection

Standard ryegrass / fescue blend:

• Most common UK turf
• 60% ryegrass, 25% fescue, 15% smooth-stalked meadow grass typical
• Hardwearing, fast-establishing, good year-round colour
• £4–£8/m² supply

RTF (Rhizomatous Tall Fescue) / all-purpose:

• Premium turf with deeper roots
• Better drought tolerance
• Slightly slower-growing, lower mowing frequency
• £8–£14/m² supply

Shade-tolerant turf:

• Higher percentage of fine fescues
• Better for north-facing or under-tree gardens
• Slower-growing, less hardwearing
• £6–£10/m² supply

Wildflower / meadow turf:

• Native flowers + grasses
• For naturalistic gardens, low-maintenance areas
• Slow to establish full bloom (year 2–3)
• £10–£18/m² supply

Site Preparation

The biggest determinant of lawn success:

1. Strip existing surface — old turf, weeds, debris
2. Cultivate to 150 mm depth — rotovator (mechanical) or fork (small areas)
3. Remove stones, roots, debris — anything larger than 25 mm
4. Apply pre-turfing fertiliser — typically 70 g/m²
5. Level and grade — final levels to fall away from house at 1:50 minimum
6. Tread or roll lightly — to consolidate, prevent settlement
7. Final rake to fine tilth — surface like a seedbed

Skipping step 6 (consolidation) is the most common cause of bumpy lawns 6 months later — the soil settles unevenly under foot and shower-head traffic.

Topsoil Quality

Topsoil should meet BS 3882 (Multipurpose grade or Premium):

• pH 5.5–8.0
• Organic matter 3–10%
• Free of stones >25 mm, glass, metal
• Low weed seed content

Cheap "topsoil" from skip-recycling sites is often contaminated — full of brick fragments, roots, weeds, and sometimes hydrocarbons. Spec a BS 3882 graded topsoil from a reputable supplier; the £15–£25/tonne saving on cheap topsoil is dwarfed by the cost of failure.

Drainage Considerations

Lawns on heavy clay or sites with high water table need drainage:

• Land drain trench at the lowest point
• 100 mm perforated pipe in 200 mm wide × 400 mm deep trench, in clean 20 mm aggregate
• Connected to existing soakaway or surface drainage
• Wrapped in geotextile to prevent silt blocking pipe

Without drainage, the lawn becomes muddy or saturated in winter — kids slipping, dogs leaving prints, pooling water.

Laying Turf

Turf laying procedure:

1. Receive turf — should arrive same day cut (or within 24 hours), watered, in rolls
2. Lay first row along the longest straight edge — usually a path or boundary
3. Subsequent rows: stagger joints — like brickwork, no continuous joints
4. Cut to fit — sharp half-moon edger or utility knife; minimise cuts
5. Tamp lightly — turf board over each row, tamp into soil contact
6. Water immediately — 25–30 mm within 1 hour of laying
7. Continue watering — daily for week 1, alternate days for weeks 2–4
8. No walk for 2–3 weeks — until rooted in
9. First mow at week 2–3 — high cut (50 mm), gradually reduce

Joint Detail

The most visible flaw on a new lawn is gaps at the joints. Critical:

• Tight butt joints — no gaps when laying
• Don't overlap — turf-on-turf creates ridges
• Top dressing (75/25 sand/peat-free compost mix) brushed into joints after watering helps fill any gaps

Seeding: When and How

If seeding instead of turf:

1. Prep as for turf but to slightly finer surface
2. Seed rate 30–50 g/m² for hardwearing mix
3. Sow by hand or push-along seeder, in two passes (90° to each other) for even coverage
4. Rake lightly — bury seed 5 mm
5. Roll to firm soil-seed contact
6. Water with fine spray — daily until germinated (10–14 days)
7. Don't walk on it for 8–12 weeks
8. First mow at week 6–8 when grass is 75–100 mm — high cut

Seeding is half the cost but adds the customer-friction of a 2–3 month establishment period during which the customer can't use the garden. Set expectations clearly.

Best Season

Turf:

• March–May: Spring planting; grass is actively growing, establishes fast
• September–October: Autumn planting; warm soil + autumn rain ideal
• Avoid: June–August (drought stress), November–February (waterlogged ground, frost)

Seed:

• April–May: Spring seeding; warming soil triggers germination
• September: Autumn seeding; warm soil + autumn rain
• Avoid: Mid-summer (drought) and winter (no growth)

Customers asking for July or December turfing — push back on the timing if at all possible.

After-Care Briefing

Customer expectations vary widely. The brief:

Week 1:

• Daily watering, 25–30 mm
• No walking on the lawn

Weeks 2–4:

• Watering every 2–3 days
• First mow at end of week 2, high cut

Months 2–6:

• Normal watering during dry spells
• Apply lawn feed at 6 weeks
• Spot-treat any patches that didn't take

Year 1:

• Full lawn establishment
• Avoid heavy traffic in first 3 months
• Annual feed spring + autumn

Edging the New Lawn

A defined edge stops the lawn spreading into beds and vice versa:

• Half-moon spade edge — labour-only, creates cut between lawn and bed; needs annual recutting
• Timber edging — pressure-treated 50 × 100 mm
• Aluminium / steel edging — premium, maintenance-free
• Concrete kerb / mowing strip — flush concrete edge that mower wheels can run on

A mowing strip (50–75 mm wide flush concrete edge) is a quality-of-life upgrade for the customer — no more strimming the edge.

Frequently Asked Questions

Why is my lawn patchy after 2 months?

Most likely causes:

1. Inadequate watering in week 1
2. Soil compaction (skipped consolidation step in prep)
3. Wrong turf for the site (e.g. shade-loving turf in full sun)
4. Poor topsoil (compacted, depleted, or contaminated)
5. Root damage from mowing too soon

Always brief the customer on watering — most "failures" are insufficient water in the first 2 weeks.

Can I lay turf in winter?

Generally not advisable. Frozen ground or waterlogged soil prevents turf rooting. Late October cut-off in southern UK; mid-October in Scotland and northern England. Resume in March/April.

Should I roll a new lawn?

Light rolling at laying (and again after watering) helps soil-turf contact. Heavy rolling compacts the soil and damages roots — avoid. A "garden roller" (water-fillable barrel roller) on its lightest setting is fine; commercial agricultural rollers are too heavy.

What about mowing height?

For first mow: 50 mm. Gradually reduce over subsequent weeks to working height of 25–35 mm for most domestic lawns. Going lower (≤25 mm) needs better-quality turf and consistent watering.

Will my new lawn survive a hot summer?

A new spring-planted lawn will need watering through its first summer. By summer 2 (after autumn establishment), it's drought-tolerant. Customers in southern UK with sandy soils may want to specify drought-tolerant RTF turf for long-term resilience.
