Homeowners whose tradespeople leave materials on their property and couples whose wedding receptions are disrupted by pests may have clearer rights than they realise, consumer lawyer Dean Dunham told readers in a recent advice column.

Dunham set out the conditions that must be met before a landowner can legally treat building materials left on their property as abandoned and explain when a venue’s failure to prevent a wasp infestation can amount to a breach of contract under consumer protection law.

On materials left by tradespeople, Dunham said the legal test is abandonment: the owner of the goods must have intentionally and voluntarily relinquished their rights to them. Abandonment is not automatic, he warned. To establish it, a homeowner should be able to show that the bricklayer or supplier failed to complete the job, ignored repeated collection requests and left the materials on site for a significant period. In practice, the lawyer said, three months is “generally long enough” to suggest abandonment but stressed that clear evidence of the owner’s lack of intention to reclaim the items is required.

Dunham advised homeowners to document the situation thoroughly. That includes taking dated photographs and preparing a detailed inventory of the items left on the property. The homeowner should then contact the tradesperson in writing, enclosing the inventory and giving a clear deadline — typically between 14 and 28 days — for collection before the materials are disposed of or sold. The letter can also warn of storage charges if the materials are not removed, which may prompt a response, he said. If the owner still does not respond after those steps, the homeowner would generally be within their rights to sell or dispose of the materials.

On weddings, Dunham told a reader whose reception was overrun by wasps that the starting point is the contract with the venue. Any specific contractual terms about the condition of the premises or agreed services should be checked first. If the contract does not address the problem directly, the Consumer Rights Act 2015 still applies. The Act requires that services be performed with reasonable care and skill, which Dunham said includes providing a venue in a suitable condition for a wedding reception.

He said a severe wasp infestation that disrupts speeches, interferes with food service and causes distress to guests will often amount to a failure to provide the contracted service with reasonable care and skill. If the venue could have reasonably anticipated or mitigated the risk — for example by using pest control measures — its failure to do so can strengthen a claim under the Act.

Remedies for a breach can include a partial refund or a price reduction to reflect the diminished enjoyment of the event. Compensation may also be available for measurable losses and for distress and inconvenience, depending on the circumstances, Dunham said. Couples seeking redress should keep evidence such as photographs, witness statements from guests and any correspondence with the venue.

Both sets of advice underline a common theme: record-keeping and clear written communication are central to enforcing consumer rights. For homeowners dealing with abandoned building materials, written notices that set out inventories, deadlines and potential storage charges create a paper trail that supports a later decision to dispose or sell. For couples, written contracts and contemporaneous evidence of disruption help establish whether a venue failed to meet its legal obligations.

Disputes that cannot be resolved through direct negotiation or an agreed refund may be pursued through consumer complaints procedures or, if necessary, in the small claims court. Dunham noted that remedies and the best route to them will depend on the facts of each case, including the terms of any contract and the quality of the evidence retained by the consumer.

The guidance serves as a reminder for consumers to check contracts carefully, document problems promptly and use written notices when seeking to enforce their rights. Tradespeople and venue operators who anticipate and address potential issues proactively — from collecting left materials to arranging pest control — can reduce the risk of disputes and possible compensation claims.
