Find an Independent Landscape, Garden or Decking Expert Witness
An Independent Garden, Landscaping or Decking Expert Witness provides specialist technical advice where garden construction, landscaping, decking or horticultural work is in dispute.
The experts listed here are experienced landscape professionals with specialist knowledge covering areas such as landscape construction, decking, paving, drainage, garden design, trees, planting and horticulture.
They may be instructed by homeowners, contractors, solicitors or insurers to inspect works, consider alleged defects and provide an independent professional opinion.
Different disputes require different expertise, so it is important to choose an expert whose experience matches the technical issues involved.
What is an Independent Garden Expert Witness?
An Independent Garden Expert Witness is a specialist with knowledge and experience beyond that normally expected of a member of the public.
Their role is to assess matters within their expertise and provide an independent, impartial and evidence-based opinion.
This may involve an independent technical assessment before legal proceedings, or formal expert evidence where required as part of a dispute or court proceedings.
Areas an Expert May Consider
Depending on the nature of the dispute, an independent landscape or garden expert may consider:
- Regulations and standards – whether relevant regulations, standards and recognised industry guidance have been followed.
- Materials – whether materials are suitable for their intended use and have been correctly specified and installed.
- Design – whether the design is appropriate and whether the completed works follow the agreed design or specification.
- Structure – whether the construction build-up, support and structural arrangements appear appropriate, and whether specialist structural advice is required.
- Decking – design, substructure, fixings, ventilation, drainage, movement and installation.
- Paving – sub-base, bedding, bonding, joints, levels, falls, drainage and workmanship.
- Walling and retaining structures – construction, stability, drainage and suitability for the intended purpose.
- Lighting – installation, positioning and potential nuisance or light-spill issues.
- Soils – suitability, preparation, compaction, drainage and growing conditions.
- Lawns – ground preparation, installation, establishment and condition.
- Horticulture – planting, establishment, suitability and plant health.
- Water management – drainage, falls, surface-water movement and flooding.
- Irrigation – suitability, coverage and operation of irrigation systems.
- Boundaries – physical boundary features and their relationship to available plans or title information.
- Workmanship – whether the completed works are consistent with reasonable professional standards and accepted industry practice.
Choosing the Right Expert
Some expert witnesses specialise in particular areas of the garden or landscape, such as decking, paving, landscape construction, horticulture or trees. It is important to choose an expert whose experience matches the technical issues in dispute.
An expert may be instructed by a homeowner, contractor, solicitor, insurer or, in appropriate circumstances, jointly by the parties.
What Type of Expert Advice Might You Need?
The type of assessment or report will depend upon the stage and nature of the dispute. This may include:
- an Independent Expert Opinion or technical assessment;
- a pre-action inspection and report;
- a CPR Part 35 expert report where expert evidence is required for court proceedings;
- a Single Joint Expert report where jointly instructed by the parties;
- further expert input such as Scott Schedules, written questions, experts’ meetings or Joint Statements where required.
An Expert Witness Must Be Independent
An expert witness is not an advocate for the person instructing or paying them.
Their role is to provide an independent, objective and unbiased opinion on matters within their expertise. Where CPR Part 35 applies, their overriding duty is to assist the court.
An expert should also make clear when an issue falls outside their expertise or when there is insufficient evidence to reach a firm conclusion.
When Might You Need an Expert?
Independent expert advice may be useful when there is a technical dispute between a homeowner and contractor about the design, construction, condition or performance of landscaping works.
For example, a homeowner may believe that newly installed paving has been laid incorrectly or that a decking structure is moving excessively. An appropriately experienced expert can inspect the works, identify the defects observed, consider their likely causes and provide an independent opinion on what remedial work may be required.
