A lush, healthy lawn is the centrepiece of the British garden, providing a space for relaxation, play, and kerb appeal. However, years of moss invasion, perenni...
Whether you are dealing with a stubborn infestation of dandelions and clover or your grass has been decimated by leatherjackets, a professional gardener can transform your garden. This guide covers everything from the initial site preparation to the final roll of the turf, ensuring you understand the costs and processes involved in achieving a bowling-green finish.
What Does the Work Involve?
- Site Assessment: Measuring the area, testing soil pH, identifying weed species, and checking for drainage issues or underground services.
- Weed Eradication: Applying professional-grade systemic herbicides to kill deep-rooted perennial weeds like docks, thistles, and couch grass.
- Turf Removal: Using a mechanical turf cutter to strip away the old, weed-infested grass layer at a consistent depth.
- Ground Preparation: Rotavating the soil to alleviate compaction and incorporating organic matter or sharp sand to improve structure.
- Levelling and Raking: Creating a fine "tilth" and ensuring the surface is perfectly level to prevent puddles and "scalping" when mowing.
- Installation: Laying high-quality, weed-free cultivated turf in a brickwork pattern or sowing premium grass seed tailored to your garden’s light levels.
- Finishing Touches: Firming the surface with a light roller, trimming edges for a crisp finish, and providing initial heavy irrigation.
- Waste Disposal: Removing all green waste and old turf from the site via a licensed waste carrier.
Typical Costs
Lawn replacement costs are primarily driven by the size of the area, the quality of the turf chosen, and the ease of access for machinery. Prices in 2025/26 reflect the rising costs of fuel and high-grade topsoil.
| Item | Low £ | High £ | Notes |
|---|---|---|---|
| Labour (per day, per person) | £250 | £450 | Higher rates in London and the South East. |
| Turf (per m²) | £5 | £12 | Standard rye-mix vs. premium ornamental turf. |
| Topsoil (per 850kg bulk bag) | £90 | £140 | Includes delivery; price varies by grade. |
| Machinery Hire (Turf cutter/Rotavator) | £80 | £150 | Daily hire rates including fuel. |
| Waste Disposal (Skip or Grab) | £180 | £350 | Old turf is heavy and expensive to tip. |
| Professional Weed Treatment | £60 | £150 | Depending on chemicals used and area size. |
Most UK homeowners should budget between £18 and £30 per square metre for a complete "strip and relay" service. Small gardens often have a higher price per metre due to fixed costs like delivery and machinery hire.
How Long Does It Take?
- Small Lawn (up to 50m²): Typically completed in 1 day by a two-person team.
- Medium Lawn (50m² – 100m²): Usually takes 1.5 to 2 days, allowing time for thorough ground prep.
- Large Lawn (100m²+): 3 days or more, often requiring larger machinery like mini-diggers.
- Seeding: Faster to "install" than turf but requires 4–8 weeks of growth before it is usable.
DIY or Professional?
While laying turf looks straightforward, the physical demand is significant. A single roll of turf weighs up to 20kg, and a medium garden may require several tonnes of topsoil to be moved by hand. Professionals have access to commercial-grade turf cutters that ensure a level finish—something nearly impossible to achieve with a spade.
Professional gardeners often hold NPTC PA1/PA6 spray certificates, allowing them to use stronger, more effective weed killers than those available to the general public in garden centres.
If you choose the DIY route, ensure you do not underestimate the waste disposal; old turf is incredibly heavy and can quickly exceed the weight limit of a standard domestic skip. For a flat, long-lasting result, professional levelling is usually worth the investment.
Choosing the Right Tradesperson
- Check Qualifications: Look for NPTC (LANTRA) pesticide application certificates if they are handling chemicals.
- Insurance: Ensure they have Public Liability Insurance (minimum £1 million) to cover any damage to your property or neighbours.
- Portfolio: Ask for photos of previous lawn replacements, ideally showing the lawn 6 months after installation.
- Red Flags: Be wary of anyone offering to lay turf directly over old grass or someone who doesn't mention soil preparation.
Questions to ask:
- What type of turf do you recommend for my garden's light and usage levels?
- Is the cost of waste removal and skip hire included in the quote?
- How long do I need to stay off the new lawn, and what is the watering schedule?
- Do you provide a guarantee if the turf fails to take despite proper watering?
UK Regulations
- Waste Carrier Licence: Any gardener taking waste away from your property must be registered with the Environment Agency as a licensed waste carrier.
- Pesticide Regulations: The use of professional herbicides is governed by the Control of Pesticides Regulations (COPR). Only qualified individuals should apply these.
- British Standards: Quality topsoil should comply with BS 3882:2015 to ensure it is free from contaminants and fit for purpose.
- Hosepipe Bans: Check with your local water authority; newly laid turf is often exempt from hosepipe bans for the first 28 days, but you may need to notify them.
Common Problems
- Sunken Patches: Caused by poor soil compaction or leaving air pockets under the turf. Professional rolling prevents this.
- Yellowing Turf: Usually a sign of underwatering or the turf being left on the pallet too long before laying (heat stress).
- Weed Return: If perennial roots aren't removed or treated with systemic killer, they will grow straight through the new turf within weeks.
- Gaps Between Rolls: Occurs when turf shrinks because it wasn't butted together tightly enough or has dried out.
- Drainage Issues: Laying turf on heavy clay without adding grit or sand can lead to a waterlogged, mossy lawn by the following winter.
Frequently Asked Questions
When is the best time of year to replace a lawn?
Spring (March to May) and Autumn (September to October) are the ideal windows. The soil is warm, and there is usually enough rainfall to help the roots establish without the scorching heat of summer or the dormancy of winter.
Can I walk on my new turf straight away?
No. You should avoid walking on new turf for at least 2 to 3 weeks. Heavy use or allowing pets on it too early can cause indentations and prevent the delicate root system from knitting into the soil.
Is it better to use turf or grass seed?
Turf gives an "instant" lawn and can be used much sooner. Seed is significantly cheaper and offers more variety (e.g., specific shade-tolerant mixes), but it takes months to establish and is highly vulnerable to birds and weeds during the germination phase.
How often should I water my new lawn?
For the first two weeks, you must water every day unless there is heavy rain. In hot weather, you may need to water twice daily. Ensure the water soaks through the turf into the soil beneath—check by gently lifting a corner of a roll.
Will the weed treatment kill my flower borders?
Professional gardeners use "selective" herbicides or apply treatments carefully on calm days to avoid "drift." If they are doing a total kill before stripping the lawn, they will usually use a shield or spray hood to protect your prize plants.
When can I first mow my new lawn?
Wait until the grass is about 2-3 inches high and the roots are firmly attached (test by gently tugging the grass). Set your mower to its highest setting for the first few cuts; never remove more than one-third of the grass blade at once.
