Alpha Decking Ltd

Composite Decking and Composite Fencing
Limited Residential Product Warranty (UK)

1. Registration Requirement (Manufacturer’s Warranty Only)

To benefit from this Limited Residential Product Warranty, you must register your Product(s) within 45 days of delivery by completing the warranty registration form on our website at alphadecking.co.uk, including submission of requested information and photographs of the installed Product(s).

Failure to register within this period means you will not be eligible to make a claim under this manufacturer’s warranty.

Failure to register does not affect your statutory rights under the Consumer Rights Act 2015.

2. Warranty Coverage

Alpha Decking Ltd (“Alpha Decking”) warrants to the original purchaser (“Purchaser”) that, for the applicable warranty period stated at the time of purchase, when used in a residential application and under normal use and service conditions, Alpha composite decking and fencing products (“Product(s)”) shall:

  • be free from material defects in workmanship and materials; and
  • not split, splinter, rot, or suffer structural damage caused by termites or fungal decay.

This warranty applies only to the Product(s) and does not include screws, clips, fixings, posts, subframes, or other ancillary accessories.

3. Residential vs Commercial Use

A residential application means installation at an individual private residence.

Any installation not meeting this definition shall be deemed a commercial application and is not covered by this residential warranty unless otherwise stated in writing by Alpha Decking.

4. Coastal Installation Limitation

All published warranty durations apply only to Product(s) installed at locations more than five (5) miles inland from the UK mainland coastline.

For Product(s) installed at locations within five (5) miles of the UK mainland coastline, the applicable warranty duration shall be reduced by 50%, and any replacement or refund shall be calculated on that adjusted warranty period.

This limitation reflects increased exposure to salt air, wind, and environmental conditions typical of coastal locations.

This limitation does not affect your statutory rights under the Consumer Rights Act 2015.

5. Warranty Remedy and Pro-Rata Schedule

If a defect covered by this Product Warranty is confirmed, Alpha Decking’s liability shall be limited, at its sole discretion, to either:

  • the replacement of the affected Product(s); or
  • a refund or credit equivalent to the remaining pro-rata value of the Product(s) at the time of the claim.

Warranty coverage is provided on a pro-rata basis, meaning the level of coverage reduces progressively over the applicable warranty period. A greater proportion of the warranty value applies during the earlier years, with the remaining value reducing over time, in accordance with the pro-rata schedule published by Alpha Decking for the relevant Product and warranty duration.

The pro-rata schedule is calculated by reference to the time elapsed since the original date of purchase and determines the maximum value of any approved claim.

Where Product(s) are installed within five (5) miles of the UK mainland coastline, the applicable warranty period shall be reduced by 50% for the purposes of calculating the pro-rata entitlement.

Labour, removal, reinstallation, haulage, delivery, and any associated or consequential costs are not covered under this warranty.

6. Non-Transferability

This warranty is non-transferable and applies only to the original purchaser who registers the warranty.

7. Exclusions

This warranty does not cover defects, failures, or damage arising from or attributable to:

  • Improper installation or failure to follow Alpha Decking installation guidelines, including but not limited to incorrect joist spacing, expansion gaps, fixing methods, heights, handling, or storage.
  • Fence installations exceeding a maximum height of 203cm without trellis or 213cm where trellis is used. This exclusion applies to affected sections and any failures reasonably attributable to excessive height or wind loading.
  • Use outside normal service conditions or contrary to applicable building regulations or Alpha Decking recommendations.
  • Movement, distortion, collapse, subsidence, or settling of the ground or supporting structure.
  • Acts of God or force majeure events, including flooding, storms, lightning, earthquakes, or other extreme weather events.
  • Wind damage, including uplift, displacement, or failure caused by:
    – wind gusts exceeding Gale Force 9 for fence heights above 183cm; or
    – wind gusts exceeding Gale Force 10 for fence heights up to 183cm.
  • Environmental conditions beyond Alpha Decking’s control, including pollution, mould, mildew, algae, salt exposure, or coastal atmospheric conditions.
  • Normal weathering, including colour fade, chalking, staining, or surface marking.
  • Variations or changes in colour or appearance, whether between boards or over time.
  • Improper handling, misuse, abuse, neglect, impact damage, or unauthorised modification.
  • Products not paid for in full.
  • Ordinary wear and tear.
  • Damage caused by accessories or third-party products not supplied by Alpha Decking.

8. Claim Notification

Claims should be notified to Alpha Decking as soon as reasonably practicable after the Purchaser becomes aware of the issue and, where possible, within seven (7) working days.

Failure to notify within seven (7) working days does not automatically invalidate a claim. However, where a delay materially prejudices Alpha Decking’s ability to investigate or assess the claim, Alpha Decking reserves the right to decline the claim or limit the remedy available.

9. Claim Information Required

Claims must include:

  • Purchaser’s full name and email address
  • Proof of purchase
  • Description of the defect
  • Date of installation
  • Date the issue was first identified
  • Installation address
  • Installer details (if applicable)
  • Photographs of the defect
  • Photographs of the installation
  • Photographs of the Product(s) in situ

Alpha Decking reserves the right to request additional information.

10. Inspection, Determination and Limitation of Remedies

Where reasonably necessary, Alpha Decking reserves the right to appoint a suitably qualified representative to inspect the Product(s) and assess the alleged defect.

Any determination made shall be final for the purposes of this Product Warranty only and shall not affect the Purchaser’s statutory rights.

Where an inspection is required and the claim is found to be valid, reasonable inspection costs will be refunded. Where a claim is found to be invalid, Alpha Decking reserves the right, where permitted by law, to recover reasonable inspection costs where such costs have been reasonably incurred.

If Alpha Decking determines that a claim is valid, Alpha Decking’s sole obligation under this Product Warranty shall be, at its discretion, either:

  • to replace the defective Product(s); or
  • to provide a refund or credit equal to the applicable pro-rata value of the Product(s).

This Product Warranty covers replacement material only. Alpha Decking shall not be responsible for costs relating to removal, installation, reinstallation, labour, delivery, haulage, or associated expenses.

The remedies set out in this Product Warranty constitute the exclusive remedies available under this Product Warranty.

11. Limitation of Liability

To the maximum extent permitted by law, Alpha Decking shall not be liable for any indirect, incidental, or consequential losses, including loss of profits, loss of use, loss of business, or loss of goodwill.

Nothing in this Product Warranty shall exclude or limit liability where it would be unlawful to do so, including liability under the Consumer Rights Act 2015.

Alpha Decking’s total liability under this Product Warranty shall not exceed the value of the replacement Product(s) or the applicable pro-rata refund.

12. Statutory Rights

This warranty is in addition to, and does not affect, your legal rights under the Consumer Rights Act 2015 or any other applicable UK legislation.

13. Severability

If any provision of this Product Warranty is found to be invalid, illegal, or unenforceable, the remaining provisions shall remain in full force and effect.

14. Amendments

This Product Warranty may only be amended by a written document issued or signed by Alpha Decking Ltd.

15. Entire Agreement, Installation Responsibility and Guidance

No person or entity is authorised by Alpha Decking to make any statement, representation, or warranty regarding the Product(s) other than those expressly set out in this Product Warranty, and Alpha Decking shall not be bound by any such statements or representations.

Alpha Decking installation guides and technical information are provided for general guidance only and may not cover every possible installation scenario. Each installation is unique, and the selection of installation methods, workmanship, and the performance of the installed Product(s) are the sole responsibility of the installer.

Alpha Decking recommends that designs, structural considerations, and installations be reviewed by appropriately qualified professionals where required, and that all installations comply with applicable building regulations, planning requirements, and permissions.

Where the Purchaser or installer is unsure of best practice, suitably qualified personnel should be engaged to ensure safe and compliant installation.

Nothing in this Product Warranty shall exclude or limit the Purchaser’s statutory rights under the Consumer Rights Act 2015 or any other applicable UK legislation.
