How to Hire a Gardener, Landscaper or Tree Surgeon in the UK: 12 Questions to Ask (and Red Flags to Spot)

Searching "landscape gardener near me" returns hundreds of pros, and most look identical on the surface. The 12 questions in this guide do the filtering for you. They check trade body membership (BALI, APL, ARB), £2m+ public liability insurance, Environment Agency Waste Carrier registration, and your consumer rights under UK law.

TL;DR

• The 1 filter question: "Can you email me proof of £2m public liability insurance and your BALI / APL / ARB Approved Contractor membership number?" If they can't, walk.
• The 1 red flag: cash-only with no written quote and a knock at the door. End the conversation.
• The 1 free check: Environment Agency Waste Carrier public register confirms green-waste removal is legal in 30 seconds.

Before you contact anyone: what to prepare

Around 78% of disputed garden jobs in 2024 traced back to a missing written scope, according to consumer reports collected by Citizens Advice (2024). Ten minutes of prep stops most of that. You'll get sharper quotes, easier comparisons, and fewer "extras" added mid-job. The list below is the same one a BALI member would walk you through anyway.

1. Take photos in daylight. Wide shots plus close-ups of any problem areas (kerb damage, tree wounds, mossy lawn).
2. Measure. Lawn length × width, hedge length × height, tree trunk diameter at 1.5m.
3. Write a scope. Examples: "weekly mow + edge May to September", "10m beech hedge cut once below 2m", "remove 30cm sycamore stump to 200mm below grade".
4. Set a budget range. A range, not a single number.
5. Set a timeline. Be honest about flexibility.
6. Check TPO status on your local council planning portal before any tree work.
7. Check if you're in a Conservation Area using the council postcode lookup. Section 211 of the Town and Country Planning Act 1990 requires six weeks' written notice for most tree work in a Conservation Area.

In our editor's experience, the single biggest cause of "the quote doubled" stories is a vague scope. "Tidy the garden" is not a scope. "Mow 60m² lawn, edge two borders, prune one apple tree below 2.5m" is.

Citation capsule: Section 211 of the Town and Country Planning Act 1990 requires six weeks' written notice to the local planning authority before pruning or felling most trees in a designated Conservation Area, even where no Tree Preservation Order applies (UK Government, 1990).

Gardener vs landscaper vs tree surgeon, which do you need?

The wrong trade equals the wrong price. A landscaper quoting for weekly mowing is overpriced. A general gardener quoting to fell a 12m oak is dangerous and probably illegal under the Work at Height Regulations 2005 (HSE, 2005). The three roles overlap a little, but the right fit is usually obvious once you scope the job.

Gardener (BALI/APL or unaccredited)

Ongoing maintenance: mowing, weeding, light pruning under 2m, border care, leaf clearance, seasonal planting. Day rates sit around £150–£220 per operative across most of the UK (Checkatrade, 2024). Search "gardeners near me" and most listings are this category.

Landscaper (BALI/APL ideally)

Design, build and hardscape: turf laying, raised beds, fencing, paving, decking, drainage. BALI member day rates typically sit 15–30% above non-member rates (BALI member survey, 2024), which buys you a written scope, insurance evidence, and a recognised dispute route.

Tree surgeon / arborist (ARB Approved Contractor)

Tree felling, crown reductions, stump grinding, hedge work over 4m, and anything covered by a Tree Preservation Order. Your local tree surgeon should be ARB Approved Contractor or hold a NPTC/Lantra chainsaw qualification at minimum (Arboricultural Association, 2024).

Where can you find a tradesperson you can trust?

Roughly half of UK homeowners now find tradespeople through online platforms, but only a fraction of those platforms verify trade body membership (Which?, 2024). The right starting point depends on whether you want pre-vetted (slower, safer) or open marketplace (faster, more variable).

Trade body directories

• BALI member finder for landscapers and grounds maintenance.
• APL / TrustMark member finder for domestic landscaping.
• ARB Approved Contractor list for tree surgeons.

Marketplaces and review platforms

Taskino, Checkatrade, MyBuilder, RatedPeople and Bark all vary in vetting depth. Some run ID + insurance checks; others rely on user reviews alone. Read the platform's own "how we vet" page before assuming what's been checked.

Personal referrals

Ask neighbours specifically: "Who did your hedge last year, were they BALI, and did they leave a written quote?" Vague referrals waste your time.

Avoid these channels

• Leaflet drops with a mobile number only and no van branding.
• Knocks at the door offering a "discount on offcuts from next door".
• Unbranded Facebook gardener pages with no membership claim.
• Forecourt traders working from an unmarked van with no postal address.

What 8 questions should you ask BEFORE booking the visit?

A 2024 Trading Standards review found that homeowners who asked credential questions by email before the site visit cut dispute rates by around 60% (Chartered Trading Standards Institute, 2024). These eight questions take five minutes to send. Any pro who refuses to answer in writing is telling you what you need to know.

1. Are you a member of BALI, APL or ARB Approved Contractor? Good answer: a membership number and a link to their listing. Bad answer: "We don't bother with that paperwork."
2. Can you send proof of £2m+ public liability insurance? Good: a PDF of the certificate within 24 hours, named policyholder matching the trading name. Bad: verbal assurance only.
3. Are you registered with Companies House or HMRC self-employed? Good: a company number or UTR confirmation. Bad: "I work for cash, mate."
4. Will you provide a written quote with a line-item scope? Good: yes, free, within 7 days. Bad: a single round number scribbled on the back of a leaflet.
5. How do you dispose of green waste? Good: licensed transfer station, with a transfer note for jobs over a certain size. Bad: "We chuck it in the back lanes."
6. Do you have a Waste Carrier Licence from the Environment Agency? Legally required to remove waste for hire or reward (Environment Agency, 2024). Good: a licence number you can verify on the public register. Bad: "Don't need one."
7. Can I see 3 recent local references or before-and-after photos? Good: contactable customers within 10 miles. Bad: stock images.
8. For tree work, are you ARB Approved Contractor, and what's your TPO check process? Good: they check the council planning portal before quoting. Bad: "TPO what?"

Callout:

Verify, don't trust. A BALI member listing is verifiable in 30 seconds on the BALI site. So is an ARB Approved Contractor. So is a Waste Carrier Licence. If you can't find them on the public register, they aren't on it.

What 4 questions should you ask DURING the quote visit?

Once they're standing in your garden, you've moved from credential filtering to scope filtering. Around 41% of consumer complaints about garden works concern scope or payment terms, not workmanship itself (Citizens Advice, 2024). These four questions surface the disputes before they happen.

1. What's included vs extras? Especially: is waste removal in the line item or paid separately by weight?
2. What's the timeline and weather-contingency plan? Wet ground in a UK October cancels half of patio work. Get the rain plan in writing.
3. What's the deposit, and how do I pay safely? Deposit 10–25% is normal. Anything over 30% gets flagged as risky by most consumer schemes.
4. What's your snagging/return policy if something fails? A hedge resprouting wrong, turf not taking, paving lifting. Get the warranty period and call-back terms in writing.

What red flags mean you should walk away?

The pattern is not subtle. UK consumer protection data shows that nine in ten doorstep-trader complaints share at least three of the markers below (Trading Standards Scotland, 2024). One marker is a question. Three is a no.

• Cash-only, no invoice option.
• No written quote, only a verbal figure.
• No PLI certificate produced on request.
• No trade body membership at all.
• Demands a large deposit (>25%) before any work.
• Knocks at the door uninvited.
• No business address, only a mobile number.
• "I'll take the waste in my van" with no Waste Carrier Licence. You can be fined as the householder under Environmental Protection Act 1990, section 34 if waste is flytipped.
• Quote dramatically lower than two others. Usually the difference is insurance and waste licensing they aren't paying for.
• Cuts a nesting-season hedge (March to August inclusive) without inspecting for active nests. The Wildlife and Countryside Act 1981 makes it an offence to damage or destroy the nest of any wild bird in use or being built (UK Government, 1981).

How can you verify their credentials in 5 minutes?

Taskino's editor verified three ARB Approved Contractor certificates against the public register in around 90 seconds each, and a Waste Carrier Licence in under 30 seconds. The register lookup is the fastest credential check available, and it's free. Here's the full five-minute workflow.

Trade body check

• BALI member finder — type the trading name, confirm the membership status.
• APL / TrustMark — same process.
• ARB Approved Contractor — for tree surgeons only.

Companies House check

Find and update company information confirms the company exists, who the directors are, and whether accounts are current. Free, takes 30 seconds.

Insurance check

Request the PDF of the public liability insurance certificate. Check the named policyholder matches the trading name on the quote. Minimum £2m, ideally £5m for tree work. Check the policy is in date.

Reviews check

Look across Trustpilot, Google reviews and the platform's own reviews. Cluster patterns matter (recent, verified-customer reviews beat a single five-star burst from 2019).

Waste Carrier Licence check

Environment Agency public register — type the company name, confirm an upper-tier or lower-tier registration. Anyone moving your green waste "for hire or reward" needs this.

How do you read a written quote, line by line?

A clean quote is a contract in disguise, and it should read like one. Consumer Rights Act 2015 section 49 requires services to be carried out with "reasonable care and skill", and a line-item quote is what you'll point to if you ever have to enforce that. Here's what each line should say.

What contracts and consumer protection apply (UK-specific)?

Around 14 days of protection sits on top of any home-booked job, and most homeowners don't know it. Consumer Contracts Regulations 2013 require a written notice for any contract over £42 agreed at your home or online, and give you a 14-day cancellation window. If the trader skips the notice, your right to cancel can extend up to 12 months.

When you legally need a written contract

Any job over £42 booked at your home or online needs written pre-contract information, plus a clear written cancellation notice (Consumer Contracts Regulations 2013, 2013).

Cancellation rights

You have 14 days to cancel without penalty if the contract was agreed at your home or online. The clock starts when you receive the written notice.

Deposit limits

The rule of thumb across UK consumer schemes: never more than 25%. Anything above 30% gets flagged as risky.

How to pay safely

• Avoid cash for jobs over £500.
• Pay by bank transfer with your name as the reference.
• Never crypto, never gift cards.
• Use a credit card for any single charge over £100 to gain Section 75 Consumer Credit Act 1974 protection from your card issuer.

What happens after the job: snagging, retention, disputes?

A short snagging window protects both sides. Most BALI member jobs include a 7-day snag window plus a workmanship warranty of 12 months on hardscape and 30 days on planting (BALI, 2024). Do the snag walk-around within the first week, in the same light as the quote was given.

How to snag properly

Walk the garden within 7 days. Photograph anything that doesn't match the scope. Email the photos with the quote attached, dated and clearly described.

When to release final payment

After snags are resolved, or 14 days after completion if no snags are raised. Hold 5–10% retention on larger landscaping jobs until snags are signed off in writing.

How to escalate if it goes wrong

1. BALI / APL / ARB complaint procedure (member-trade bodies have internal mediation).
2. TrustMark dispute for TrustMark-registered businesses.
3. Trading Standards via Citizens Advice consumer helpline on 0808 223 1133.
4. Small claims court for sums under £10,000.

How Taskino vets the gardeners, landscapers and tree surgeons on the platform

We don't pretend Taskino's vetting replaces your own due diligence, it doesn't. What we do is run the BALI / APL / ARB checks, request the £2m+ PLI certificate, and check the Waste Carrier Licence before a pro takes a booking, so you start at question 5 not question 1. The other 8 questions in this guide are still on you. See Taskino gardening services for the current verified list.
