How Much Does Lawn Care Cost?

Want to know how much treating a lawn costs in 2026?

The average lawn treatment service cost is around £45 for a one-off treatment.

Usually, lawn care specialists will offer some type of monthly or annual package to their customers, saving you money and guaranteeing them business. Regular treatment is the key to maintaining a luscious lawn.

A simple way to calculate the cost of treating a lawn on a one-off treatment basis is by knowing the average cost per m², which is around £0.21.

The cost of lawn treatment will vary depending on the type of treatment, the size and the condition of your lawn. Before they begin, the gardener will be able to clarify lawn treatments and costs with you.

How can I quickly kill off my lawn to lay a new one?

"The best advice I would give is just to take up the old lawn before laying new. Grass is hard to kill, and guaranteed there will be some that will survive just grow through the new turf, which, if the existing grass isn’t much good, would spoil a new lawn."

My new lawn is patchy with areas where the grass isn't growing. How can I fix it?

"I’d suggest ensuring the ground stays damp, avoid walking over it, and spread the area with grass seed and feed. While the grass is young, cut it regularly, and keep uniform length - but do not cut more than a 1/3 off at a time."

Factors That Impact Lawn Care Costs

Type of Treatment — Some products, such as fungicides, are different from fertilisers and may cost more to apply. Organic products can also be more expensive than standard alternatives.
Lawn Condition — Lawns in worse condition may need more intensive treatment, taking up more time and product and increasing the overall cost.
Lawn Size — Larger areas will require more product and take longer to treat. However, labour costs for bigger lawns may be cheaper per square metre due to the use of more efficient commercial equipment.
Number of Treatments Needed — Some lawns may require multiple treatments to tackle existing problems. If moss, weeds, or compacted soil are present, labour costs will increase accordingly.
Location — Where you are in the UK can affect both product costs and labour rates. Lawn care costs in London and the South East tend to be higher than in rural areas.
Labour Costs — Gardeners and lawn care businesses set their own rates, so prices for lawn treatment services will vary from contractor to contractor.
Who you Hire — Prices will vary based on whether you hire a local independent lawn treatment service or a national lawn care company such as Greensleeves or Green Thumb, which offer structured treatment programmes to treat your garden every month or year.

How do you prep ground for grass seed?

"You should clear the area and remove any large stones, weeds, and other debris. It's easier to fix soil problems before your new lawn is in place. For clay soils, mix in sharp sand to aid drainage and composition."

What's Involved in Treating a Lawn?

With there being multiple types of lawn treatment services, the process will vary depending on the treatments your lawn requires.

Most homeowners choose to hire a professional tradesperson for the best results.

With MyJobQuote, you can request several quotes from local lawn care specialists. It's fast, free, and there is no obligation to go ahead.

Here is a general overview of what to expect when you hire a lawn treatment service:

Before the Job Starts

Lawn Assessment — A professional will inspect your lawn to identify any issues, such as moss, thatch, weeds, or pest damage, and recommend the most appropriate treatments.
Measuring the Lawn — The lawn care specialist will measure the lawn size to calculate how much product is needed and estimate how long the job will take.

During the Job

Spray-on Treatments — Lawn feed, fertilisers, fungicides, and nematodes are applied by being sprayed directly onto the lawn, focusing on specific areas. Nematodes require the lawn to be watered beforehand to aid absorption.
Scarification and Aeration — Specialist equipment is used to break up compacted areas and remove thatch. These methods can become messy, and some clean-up is likely required afterwards.
Topdressing and Overseeding — A layer of compost is spread across the lawn to provide nutrients to the grass roots, before being raked in. New grass seed may also be sown to fill any bare or patchy areas.

After the Job

Aftercare — Some treatments should not be watered in immediately, while others (such as nematodes) require watering straight after application. Always follow your contractor's advice.
Follow-up Visits — Many lawn care specialists will recommend a seasonal programme to maintain results and keep your lawn looking its best throughout the year.

Are different rakes necessary for the lawn, or is there one that's suitable for all maintenance jobs?

"We usually find that a fine, multi-pronged rake does the job. Raking the lawn with this usually allows you to remove all the dead grass and allow new grass to come through.

So although once raked it may look a little bare, it is ultimately for the greater good — which in this instance would be a lush, green space."

Types of Lawn Treatments

Here are a few types of different lawn treatments you can have:

Watering

Perhaps the most obvious treatment, watering your lawn, can solve most simple problems. The average lawn requires one inch of water per week, so be sure to monitor the rainfall alongside your watering levels.

You can do this with a rain gauge, which will help you decide whether to water your lawn or not. One way to know if your lawn needs watering is if footprints are left behind after being walked over.

Fertiliser

Fertiliser is essentially food for your lawn, encouraging it to grow strong and vibrant. Different fertilisers suit different issues and should be applied at different times of the year, so it is important to read the labels carefully.

If your grass has bare patches, use a fertiliser that is high in phosphorus content, as this will encourage root development.
If your grass is extremely dry, use fertiliser that is high in potassium, as this will improve tolerance to disease and drought.
If you want a thick, healthy lawn, use a fertiliser that is rich in nitrogen, encouraging growth and greener grass.

This tends to be the most popular spring lawn treatment.

Aeration and Scarification

Harsh winters and heavy usage can leave a lawn looking flat and tired due to the compacted soil and thatch that forms over the surface. Evidence of this is dead patches of grass, as pathways for water and nutrients are blocked, and the roots become parched.

Methods such as aeration and scarification can help create new pathways for these elements to reach the roots and promote growth and regeneration.

This tends to be the most popular autumn lawn treatment.

Pre-Emergent and Targeted Weed Control

Preventing weeds from growing helps maintain the health of your lawn. Having a thick, healthy lawn is the best and most simple way to achieve this, making it harder for weeds to grow.

If you are concerned that this is not enough for your lawn, you can use pre-emergent herbicides to prevent them before they even begin to appear. However, if weeds have already begun to grow, you can use herbicides to get rid of them.

It is worth considering using natural remedies and weed killers rather than chemical solutions, as they are far better for the health of your grass and the environment in general.

In order to be able to banish weeds from your lawn, you will need to know:

The type of weed you are trying to eliminate
When they grow (to be able to stop them before they start)
How to get rid of them

Vinegar or boiling water may kill individual weeds but can also harm surrounding grass and soil—use with caution, or consider professional weed control.

Pesticide Regulations in the UK

There are multiple laws and regulations surrounding the use of garden pesticides and Plant Protection Products that limit their usage and regulate who is able to purchase and apply them.

Pesticides and PPPs often contain hazardous chemicals which must be stored and applied properly in order to sustain the safety of others. Professionals using certain pesticides must have a qualification in their usage and evidence of appropriate training.

Anyone using pesticides will also have a responsibility to take precautions in accordance with HSE guidelines.

Pesticides intended for amateur/domestic use usually don’t need certification, but products authorised for professional use do. Professionals must follow HSE rules—failure to comply can result in prosecution.

It is recommended to use organic pesticides over chemical ones, which are far more environmentally friendly and pose less risk to the user.

These regulations can be intimidating, and so if you are unsure how best to follow them or do not feel confident with using pesticide products, hiring a professional may be the best option for you.

Checklist: Hiring a Lawn Treatment Service to Treat a Lawn

Here is what to look for when hiring a tradesperson to treat your lawn:

Do they have the correct certification? Any professional lawn service applying pesticides commercially should hold a PA1/PA6 certificate or equivalent.
Are they a member of a recognised trade body or accreditation scheme? Look for BASIS PROMPT registration and LANTRA accreditation, both of which indicate a higher standard of professional competency in lawn care.
Do they have insurance? Public liability insurance protects you in case something goes wrong during your lawn treatment.
Will they provide an itemised quote? Ask for a breakdown of lawn care costs so you know exactly what is included and whether any lawn treatments are priced separately.
Do they have positive reviews? Check their MyJobQuote profile to read feedback from previous lawn treatment customers.
Do they have examples of previous work? Look for lawn treatment photos on their MyJobQuote profile to give you an idea of the results you can expect.

FAQs

What is Revive Lawn Treatment?

Revive Lawn Treatment is a natural soil treatment made from organic materials and perfect for dried-out lawns. Here are the benefits:

Aids water penetration - Revive has a special "wetting agent" that helps hydrate hard-to-wet soil.
Helps essential nutrients "break free" from the soil for absorption - Acting as a "chelating agent", Revive stops iron and zinc from getting locked up in the soil, making them available for plants and roots to absorb to promote healthy grass growth.

What is the best lawn treatment?

The best lawn treatment depends on your lawn issues, but a balanced approach would be to ensure your grass is mown regularly to promote healthy growth and to ward off weed growth, as well as being well-watered.

If you have issues with a patchy lawn, you should overseed and fill in patches with new grass seed, and if you have trouble with your soil, you can consider a lawn treatment like Revive to mitigate moisture issues.

I applied my own lawn treatment, but I have not seen any improvements. Why?

Lawn improvement is not instant, and it can take time to see results - anywhere from 1 to 8 weeks, depending on your treatment.

If you've tried some DIY methods and still haven't seen any difference after a few months, you could consider hiring a gardener to get their specialised advice.

Is it a good idea to treat my own lawn?

If you know the exact problem with your lawn, there are lots of products available to help you treat your own lawn. However, you should make sure you know your exact grass problem before starting new treatments, as improper care can lead to bigger problems.

If you're unsure about your exact lawn issues, contact a professional gardener for their advice.

How frequently should I treat my lawn?

Lawns benefit most for treatments during Spring, Summer and Autumn, but treating your lawn twice a year can be enough to keep your garden healthy. However, it could be necessary to treat lawns more frequently to avoid the presence of pests, specific diseases or weeds.

How can I keep my lawn healthy?

Here are some tips to keep your lawn at optimal health:

Regularly mow your lawn to promote root spread and lessen weed growth, keeping it at around 3 inches high. Make sure you don't cut more than 1/3 of the length off in any mow.
Keep your lawn hydrated by watering it. This is best done in the morning before the sun rises to ensure your lawn absorbs the moisture rather than it being evaporated by the sun.
Fertilise your lawn to help fill in any gaps, and aerate with an aeration tool to help root nutrient absorption.
Remove weeds when you see them, and remove the layer of thatch (around half an inch of dead grass on top of your lawn) to ensure water and nutrients get to the soil and roots.

Is it safe for my children and pets to use the lawn after the treatment?

You should always check your lawn treatment instructions, as there will be different timelines for each product. If you've used a chemical-based lawn treatment, you're likely to need to wait for a longer period than if you've used an organic treatment.

Can I use pesticides to treat my own lawn?

You can use pesticides if they have been designed for domestic use. These pesticides do not require a cerfication to be handled, but it is crucial to follow their instruction and guidelines carefully. Failure to comply with these requirements may result in legal action and even prosecution. Hiring a professional is highly recommended. They have the equipment, the expertise and the knowledge, and you won't have to worry about anything.

What is the difference between organic and chemical pesticides?

Organic pesticides are made from natural substances like minerals or plants and they are generally safer for people and pets. Chemical pesticides are syntethic compounds, stronger than the organic pesticides, and made to last longer. Chemical pesticides pose a significant risk to health and environment due to their toxicity. If you are unsure about which type of pesticides to choose, we suggest to consult a professional gardener or a licensed contractor for advice.

Can I treat a lawn myself?

Some lawn treatments may be easy to DIY, such as scarification, aeration and surface-level treatments. Lawn scarifiers can be purchased for around £30 to £60, aerator forks for £15 to £45, and lawn feed from as little as £4. Pesticides and fungicides can also be purchased for around £30, though it is highly recommended to hire a professional lawn treatment service that is certified to apply them.
