Your Rights When a Guaranteed Pest Treatment Fails

When a guaranteed pest treatment fails, your rights come from consumer law, not only from the trader's own promise. Every consumer service contract requires the work to be performed with reasonable care and skill. Where it was not, you have a right to have the service performed again at no extra cost, and to a price reduction if that repeat is not delivered.

What can you do if a pest treatment does not work?

You can require the work to be done again, free of charge. Every consumer contract for a service carries an implied term that the trader will perform the service with reasonable care and skill. Where that term is breached, the consumer has a right to repeat performance, meaning the trader must perform the service again at its own cost. The order is the point: repeat performance comes first, money second.

What counts as a failed treatment rather than a normal outcome?

A treatment has failed when the work was done without reasonable care and skill, not simply when pests are still present after the first visit. Several UK treatments are designed as multi-visit protocols. A bed bug or flea insecticide programme normally runs as two or three applications 10–14 days apart, because residual products kill nymphs as eggs and pupae hatch rather than killing the eggs. Live insects between booked visits are the protocol working.

Two situations get mistaken for a failure, and each carries its own answer:

• An incomplete treatment cycle. Visits are still to run, so the service has not finished being performed. Attend the booked follow-up, and log sightings by date meanwhile.
• A re-infestation from a new source. Mice return through a gap never surveyed, bed bugs arrive in luggage, rats move in from next door or a broken drain. A new route is new work, and new work is a new contract.

What does work done without reasonable care and skill look like?

Work done without reasonable care and skill is a genuine failure: the wrong room was treated, a loft named at booking was never inspected, no follow-up was offered when the method requires one, or a product was applied in a way its label does not permit.

The CRRU UK Code of Best Practice restricts permanent rodent baiting, so a professional who removes bait points when a programme ends is following stewardship rules rather than abandoning the job. The scope agreed at booking decides whether careless work or a new entry route is to blame, and a trader's own guarantee is a separate promise sitting on top of that scope.

What is repeat performance, and when can you insist on it?

Repeat performance is the trader redoing the service until it matches what was agreed, at no cost to you. The trader must bear any necessary costs, including labour, materials and travel, and must carry the repeat out within a reasonable time and without significant inconvenience to the consumer. You cannot be charged a second callout fee for it.

You can insist on repeat performance once the agreed service has been delivered and has not worked because of the way it was performed: the booked visits are complete, the stated follow-up window has passed, and the same pest is still active in the same place.

How quickly does the repeat visit have to happen?

A reasonable time for the repeat visit is measured against how quickly the trader attends work it is being paid for, so the speed it advertises to new customers sets the benchmark. 247 Pest Control states that same-day attendance is available across London and responds to emergency enquiries 24/7, while noting that attendance time cannot be identical for every call. That inspection is what turns an urgent call into a plan: the species named, the treatment chosen, and the earliest date it can happen. A trader who turns out to new enquiries at that speed has little ground for treating a repeat visit as something that can wait weeks.

When can you ask for money back instead?

You can ask for money back where repeat performance is impossible, or where the trader has not provided it within a reasonable time and without significant inconvenience to you. The remedy is then a price reduction of an appropriate amount, which can run to the full amount paid.

Two things make repeat performance impossible rather than merely late. Either the pest problem has been resolved another way, so there is nothing left to treat, or the trader refuses to return, stops responding, or ceases trading. A price reduction is measured against what you paid, so the quotation matters. 247 Pest Control publishes rat and mice control from £214 and bed bug control from £234 for straightforward domestic treatments, and names pest type, property size, infestation level, visits needed, treatment method, access and urgency as the variables that move a figure.

What should you do first, in order?

Recontact the company in writing before doing anything else. The sequence matters when a guaranteed pest treatment fails, because each step either resolves the problem or builds the record the next step needs.

1. Write, do not just ring. Email or use the company's contact form, so the date of your complaint is fixed in writing.
2. State what was found and when. Give the species, the room, the dates of each sighting and the date of the original treatment. Dated evidence separates a failed treatment from a re-infestation.
3. Ask for repeat performance by name. Ask, in those words, for the service to be performed again at no additional cost, so the trader is answering the remedy you are entitled to rather than a general complaint.
4. Keep the treatment record and the photographs. The technician's report, the products used, the invoice and dated photographs are the evidence base for a later claim.
5. Let the stated follow-up cycle finish. If the method involves further visits, allow them; a complaint made mid-cycle is usually answered by the next booked visit.
6. Set a deadline, then escalate. Give a date in writing by which you expect the revisit. If it passes, claim a price reduction instead, and say what you paid in the same message.

Where do you escalate to?

Escalate to the trader's own complaints procedure first, then to a trade body, then to Citizens Advice and Trading Standards, and to the courts last. Traders are entitled to a chance to put things right first.

• The trader's own complaints route. Ask for the complaints procedure in writing and for a named point of contact, and keep the reply.
• A trade body's complaints procedure. Members of the British Pest Control Association (BPCA) are audited and bound by its Codes of Best Practice and its complaints process, and membership can be checked on the association's own member register before booking.
• Citizens Advice and Trading Standards. The Citizens Advice consumer service records the complaint and refers matters to Trading Standards, which acts on unfair trading practices rather than awarding compensation.
• The small claims track. In England and Wales, the small claims track normally handles money claims up to £10,000. Bring the invoice, the written complaint, any reply and the dated evidence.

FAQs

Can I get a full refund if a pest treatment did not work?

A full refund is possible but not automatic. Where a service was not performed with reasonable care and skill, you have a right to a price reduction of an appropriate amount, and that can be the whole price where nothing of value was delivered. It applies where repeat performance is impossible, or has not been provided within a reasonable time.

How long is a reasonable time for a repeat pest control visit?

No fixed period is set, so a reasonable time is judged against the pest and the method. A wasp nest revisit is a matter of days, a bed bug re-treatment fits the normal 10–14 day insecticide cycle, and a rodent programme is judged over four to six weeks of monitoring. Put your expected date in writing.

Does a company guarantee replace my statutory rights?

No. A guarantee sits on top of your consumer rights rather than displacing them. The duty to perform a service with reasonable care and skill applies whether or not a guarantee was offered, and an expired guarantee does not remove your right to repeat performance or to a price reduction where the work was done badly.

Can I cancel a pest control booking made over the phone?

Yes. A consumer who agrees a service contract at a distance or away from the trader's premises has 14 days to cancel. If you asked for the work to start inside that period, you can be charged for what has already been supplied, and the right to cancel ends once the service has been fully performed at your express request.

Does hiring a British Pest Control Association member change my remedies?

Your remedies are identical either way, because the same consumer rules apply to every trader. What British Pest Control Association (BPCA) membership adds is an external complaints procedure, audited membership, the association's Codes of Best Practice, and a member register you can check before booking.
