UK orders are usually dispatched via EVRI Next Day delivery. Orders received before 12pm on a business day will normally be dispatched the same day. Orders received after 12pm, at weekends or on bank holidays will normally be dispatched on the next business day.

International orders are arranged individually with the customer. We will contact you to agree the most appropriate courier service and delivery option for your location before dispatch.

Delivery times are estimates and may vary depending on the destination and courier service selected. Once an order has been handed to the courier, delays can occasionally occur which are outside Mould Lab's control.

Tracking information will be provided where available.

All of our test kits are supplied with clear, detailed sampling instructions to guide you through the process.

You don't need to wait for your kit to arrive to get started. A link to the relevant instructions is included in your order confirmation email via the large green button, allowing you to review the sampling process and prepare in advance.

A copy of the instructions will also be included with your kit.

If you have any questions or are unsure about any part of the sampling process, please email us at info@mouldlab.co.uk and we'll be happy to assist.

We take care to ensure all test kits are securely packaged before dispatch. However, occasionally damage can occur while an order is in transit.

If your order arrives damaged, please contact us as soon as possible at info@mouldlab.co.uk, including photographs of the packaging and any damaged contents where possible.

We will review the issue and, where necessary, arrange for damaged testing materials or equipment to be replaced so that you are able to complete your test.

For UK orders where Mould Lab has arranged the return shipping, we will provide the appropriate return service for sending your samples to the laboratory.

Once your sample has been handed to the courier, its transportation is undertaken by the courier and delays, loss or damage in transit can occasionally occur outside of our control.

If there is an issue with a shipment arranged by Mould Lab, please contact us and we will liaise with the courier on your behalf and do everything reasonably possible to resolve the issue. Where a sample is confirmed as lost or damaged and cannot be analysed, we will work with you to determine the appropriate next steps, which may include providing replacement sampling materials so that a new sample can be collected.

For international customers, return shipping is arranged by the customer. We are happy to provide guidance and assist with shipping documentation where required, but Mould Lab cannot accept responsibility for loss, damage or delays relating to return shipments arranged independently by the customer.

Once we receive your sample, it will be forwarded to the appropriate laboratory for analysis. Samples sent by Mould Lab to our overseas laboratories are usually shipped via FedEx Express, with delivery typically taking 1–3 business days.

We will do our best to confirm when your sample has been received by Mould Lab and, once the laboratory has confirmed receipt, we will provide you with an estimated date for your results.

Laboratory turnaround times vary depending on the test purchased and begin once the laboratory receives your sample, not when you post your sample back to us.

The estimated turnaround time for each test is also shown on the relevant product page. Please note that turnaround times are estimates and do not include shipping time to the laboratory, weekends, bank/public holidays or unexpected courier or laboratory delays.

Once your results are available, they will be sent to you by email.

Occasionally, a laboratory may be unable to process a sample or may report that a result is inconclusive. This can happen for a number of reasons, including insufficient sample material, an issue with the way the sample was collected or stored, contamination, or a technical issue during analysis.

It is important that the sampling instructions supplied with your test are followed carefully, as Mould Lab cannot accept responsibility where a sample cannot be analysed due to incorrect collection, handling or storage by the customer.

If the laboratory is unable to process your sample, we will contact you to explain the reason provided by the laboratory and advise you on the appropriate next steps.

Where appropriate, this may include arranging replacement sampling materials so that another sample can be collected. Any additional laboratory analysis or shipping costs will depend on the reason the original sample could not be processed and will be discussed with you before proceeding.

If the issue is confirmed to have resulted from a laboratory or Mould Lab error, you will not be charged for the repeat analysis.

We already use the fastest appropriate courier service available to send samples to our laboratories, so unfortunately we are unable to expedite shipping further.

Laboratory turnaround times are set by the individual laboratories and, for most tests, cannot be expedited.

The exception is our ERMI testing, where a 1-business-day laboratory turnaround option is available in addition to the standard service. This option must be selected when purchasing your test.

Turnaround times begin when the laboratory receives your sample and do not include shipping time, weekends or bank/public holidays.

If you have a particular deadline, please contact us before ordering and we can advise whether the expected timescale is likely to meet your requirements.

Yes, we can send most of our test kits internationally.

International shipping is arranged individually, as courier options, costs and delivery times vary depending on the destination and the test being ordered. We will discuss the available options with you and agree the most appropriate courier service before your order is processed.

The agreed shipping cost will be added to your invoice. Where applicable, VAT can be removed for eligible international customers. International orders arranged in this way will need to be paid by bank transfer.

Please note that return shipping of samples to Mould Lab or the laboratory is the responsibility of the customer, as we are unable to arrange courier collections outside of the UK. We will, however, provide guidance and assist with the necessary shipping or customs paperwork where required.

Customers are responsible for any import duties, taxes or other charges that may be applied by their destination country.

If you are ordering from outside the UK, please contact us and we will be happy to help arrange the most suitable shipping option.

Absolutely. We offer a range of different tests depending on what you are trying to investigate, so we understand that choosing the right one can sometimes feel confusing.

Our Test Finder Questionnaire asks you a few simple questions about your property, concerns and what you are hoping to find out, and will recommend the most appropriate testing options for your situation.

If you're still unsure after completing the questionnaire, please email us at info@mouldlab.co.uk and we'll be happy to help.

Yes. We understand that laboratory reports can sometimes feel overwhelming or difficult to interpret, so we provide information and guidance to help you understand your results and what the findings may mean.

For many of our environmental and body tests, the laboratory also provides an overview alongside your results to help explain the findings and give additional context to the results reported.

For additional educational guidance relating to mould and the indoor environment, you can also access Jeff Charlton AI through Talking Mould. Jeff AI draws on Jeff Charlton’s extensive knowledge and experience in water damage, mould and biological contamination, together with a wide range of scientific and professional resources, and can help you explore questions about your environmental results, concerns and potential next steps.

Please remember that Mould Lab provides laboratory testing services, information and educational guidance. We cannot provide medical advice, interpret results as a medical diagnosis or diagnose health conditions. If you have concerns about your health, or wish to understand how your body or environmental test results may relate to symptoms or a medical condition, you should discuss these with an appropriately qualified medical professional.

If your environmental results suggest that further investigation of your property may be appropriate, we can also explain the types of professional investigation available to help you decide on your next steps.

Yes. We believe it is important to be completely transparent about our relationship with Building Forensics. Mould Lab and Building Forensics are sister companies, with family connections between the businesses.

Where test results indicate that further professional investigation of a property may be appropriate, we may recommend Building Forensics. This recommendation is based on the extensive qualifications, training, knowledge and experience of Jeff Charlton, Building Forensics’ lead environmental hygienist, together with the company’s specialist experience in investigating water damage, damp, mould, indoor air quality and other building-related environmental issues.

Our connection with Building Forensics does not affect your laboratory results, which are produced by the relevant independent laboratory.

You are also under no obligation to use Building Forensics. You are welcome to appoint any suitably qualified independent professional of your choice to carry out further investigation or remediation.

Our aim is to help you understand the options available and make an informed decision about what, if anything, you wish to do next.

No. Our tests can provide valuable information about your indoor environment or specific markers measured in a body sample, but they cannot determine on their own whether mould or another environmental exposure is causing particular symptoms or a medical condition.

Our environmental tests can identify and quantify moulds, mycotoxins and other environmental contaminants, depending on the test selected. Our body tests measure the specific mycotoxins, antibodies, metabolites or other markers included within the chosen laboratory analysis.

These results can provide useful information and may help you and your healthcare professional build a clearer picture, but they do not constitute a medical diagnosis or establish a direct link between an environmental finding and your symptoms.

If you are experiencing symptoms or would like your results interpreted in the context of your health, we recommend discussing them with an appropriately qualified healthcare professional.

Mould Lab is always happy to help with questions about the testing process, laboratory report and the environmental aspects of your results, but we cannot provide medical advice or diagnosis.
