The evaluation points

Nineteen factors, three weights. Safety-critical points count ×3, important points ×2, and adjacent services ×1. This is the full rubric behind every score on this site - so you can see exactly how we reach a conclusion, and disagree with it if you want to.

Safety-critical · ×3

The seven factors that decide whether a job is done safely and legally. If a firm can't evidence these, nothing else matters.

Important · ×2

The seven factors that decide how good the experience is - coverage, reputation, experience, surveys, maintenance, waste, communication.

Adjacent · ×1

The five extras that are useful to know about but irrelevant to tree-work quality - lawn care, pest control, garden work, firewood, fencing.

Safety-critical (×3)

NPTC / City & Guilds qualifications

weight ×3

What we look for: Chainsaw and tree-work competence recognised by NPTC / City & Guilds (the industry standard).

Why it matters: Tree work is one of the most dangerous trades in the UK. A qualified operator is the single best predictor of a safe job. Anyone can own a chainsaw; qualifications show assessed competence.

Ask any firm:

  • Ask to see the qualification certificates before work starts.
  • Check they cover climbing and aerial rescue, not just ground chainsaw use.

Public liability insurance

weight ×3

What we look for: Current public liability cover - £5M is a sensible floor for tree work; £10M is better near buildings.

Why it matters: A falling branch or tree can damage a roof, a car or a person. If a firm is uninsured or underinsured, you carry that risk. Ask for the certificate, not a promise.

Ask any firm:

  • Ask for a copy of the current certificate before quoting.
  • Check the policy covers tree work specifically, not just general gardening.

BS3998 working standard

weight ×3

What we look for: Work carried out to BS3998 - the British Standard for tree work.

Why it matters: BS3998 is the accepted benchmark for pruning and tree operations. Firms that cite it signal they understand tree health, wound response and correct cuts - not just "making it smaller".

Ask any firm:

  • Ask whether pruning work follows BS3998.
  • Be wary of firms that only talk about "chopping" or "cutting back" without mentioning tree health.

Site-specific risk assessments (RAMS)

weight ×3

What we look for: A written risk assessment and method statement prepared for your specific site before work begins.

Why it matters: Generic paperwork is cheap. Site-specific RAMS mean the firm has actually thought about your access, your buildings, neighbours, wildlife and weather before they turn up.

Ask any firm:

  • Ask whether you will receive site-specific RAMS before the job.
  • For commercial sites, a firm that cannot produce RAMS on request should be a red flag.

TPO & conservation-area handling

weight ×3

What we look for: Understanding of Tree Preservation Orders and conservation-area rules, including applying to the council for consent.

Why it matters: Cutting a protected tree without consent is a criminal offence with fines up to £20,000 in England. North Yorkshire and York are full of protected trees - this is not an edge case here.

Ask any firm:

  • Ask the firm to check TPO and conservation-area status before they quote.
  • Ask whether they will handle the council application for you.

Emergency response

weight ×3

What we look for: A credible emergency service for storm damage, fallen trees and dangerous branches - ideally with a clear phone process.

Why it matters: After a storm, the firms that answer the phone quickly are the ones that stop the damage. If a firm has no emergency process at all, you are gambling on good weather.

Ask any firm:

  • Ask what happens when you call about a storm-damaged tree - who answers, and how fast?
  • Ask whether emergency work is priced differently before the job, not after.

Free, itemised written quotes

weight ×3

What we look for: A free quote, in writing, itemised enough that you know what you are paying for.

Why it matters: Vague verbal prices drift. A written, itemised quote forces the firm to think the job through and gives you something to hold them to.

Ask any firm:

  • Ask for the quote in writing before any work starts.
  • Ask what happens if the job turns out harder than expected - who eats the difference?

Important (×2)

North Yorkshire coverage

weight ×2

What we look for: Genuine, local coverage of your part of North Yorkshire - not just a listing page claiming it.

Why it matters: A firm with local knowledge understands local tree species, soils, exposure and council rules. It also means shorter emergency response and lower travel costs.

Ask any firm:

  • Ask which towns and villages they actually work in week to week.
  • Ask how far away their nearest crew/operator is based.

Reviews & reputation

weight ×2

What we look for: Verifiable, recent reviews - ideally with volume - on Google or Checkatrade, or named customer quotes.

Why it matters: Reviews are the closest thing to word of mouth at scale. Volume matters: 5.0 from 7 reviews is not the same as 5.0 from 300.

Ask any firm:

  • Ask for the firm's Google profile link, not just "we have great reviews".
  • Read how they respond to any negative reviews - that tells you a lot.

Experience depth

weight ×2

What we look for: Years in business and the range of work done - dangerous removals, conservation areas, commercial sites.

Why it matters: Experience shows up in judgement: knowing when a tree can be saved, when it must come down, and how to rig it down without damaging your garden.

Ask any firm:

  • Ask about the hardest or most awkward job they have done recently.
  • Ask whether they have worked on commercial or estate sites.

Tree surveys & reports (BS5837)

weight ×2

What we look for: Ability to provide tree surveys and reports for planning, mortgage, insurance or safety purposes (BS5837).

Why it matters: If you are buying, selling, building or simply managing a large tree, a proper survey with a written report is worth having. Few local firms offer it.

Ask any firm:

  • Ask whether they provide written tree reports and BS5837 surveys.
  • Ask what a report includes and who stands behind it.

Scheduled maintenance plans

weight ×2

What we look for: Ongoing, scheduled tree and hedge care - not just one-off jobs.

Why it matters: Trees grow every year; problems get more expensive the longer they are ignored. A firm that offers scheduled visits is thinking long-term about your property.

Ask any firm:

  • Ask whether they offer regular visits and what they cost.
  • Ask whether you can pause or cancel without penalty.

Waste removal & tidy finish

weight ×2

What we look for: Branches, timber and chippings removed - and a registered waste carrier if waste leaves your site.

Why it matters: "We'll sort the waste" is a promise; a registered waste carrier is a legal obligation. Tidy finish is the difference between a job that feels done and one that does not.

Ask any firm:

  • Ask whether the price includes removing all waste.
  • Ask whether they are registered waste carriers (check the Environment Agency register).

Straight advice & communication

weight ×2

What we look for: Honest advice - including when work is not needed - and clear communication from quote to completion.

Why it matters: A good tree surgeon should sometimes talk you out of work. If every visit ends with a bigger quote, that is a sales pitch, not advice.

Ask any firm:

  • Ask what they would do if they thought a tree did not need work.
  • Ask who does the work - the person you spoke to, or a subcontractor.

Adjacent services (×1)

Lawn care

weight ×1

What we look for: Whether the firm offers lawn care or turf services alongside tree work.

Why it matters: Useful if you want one contractor for everything, but lawn care is a different trade from tree surgery. For tree work itself it is irrelevant.

Ask any firm:

  • If you need lawn care, check the firm is competent at it - or hire a specialist.

Pest control

weight ×1

What we look for: Whether the firm offers pest control services.

Why it matters: Pest control is a licensed, separate trade. Firms that list it alongside tree surgery are generalists. That is fine - but it says nothing about tree-work quality.

Ask any firm:

  • Check pest control is separately licensed and insured if you plan to use it.

Small garden & general maintenance

weight ×1

What we look for: Whether the firm takes on small garden jobs and general maintenance.

Why it matters: Convenient if you need a one-stop shop. But general garden work is not tree surgery - and the best tree specialists usually do not chase it.

Ask any firm:

  • If you need garden maintenance too, weigh up one contractor vs a tree specialist plus a gardener.

Firewood supply

weight ×1

What we look for: Whether the firm sells firewood from removals.

Why it matters: A nice side benefit if you have a wood burner, but irrelevant to the quality of tree work.

Ask any firm:

  • Ask about seasoning and moisture content if you buy firewood from a tree firm.

Fencing & landscaping

weight ×1

What we look for: Whether the firm also does fencing or landscaping.

Why it matters: Valuable if your project combines tree work and fencing. Otherwise it is a different trade with different skills.

Ask any firm:

  • Check fencing work is separately quoted and warranted if you combine it with tree work.
