Terms of Service

Professional EEG lie detection testing services. Please read these terms carefully before booking our services.

Last Updated: July 19, 2026

1. Acceptance of Terms

By booking our services, accessing our website, or engaging with DeceptionDetection.co.uk in any capacity, you agree to be bound by these Terms of Service and all applicable laws and regulations. If you do not agree with any of these terms, you are prohibited from using or accessing our services.

1.1 Legal Agreement

These terms constitute a legally binding agreement between you (the "Client") and DeceptionDetection.co.uk (the "Company", "we", "us", or "our").

1.2 Age Requirements

Our services are available only to individuals aged 18 or over. We do not test anyone under the age of 18 under any circumstances, and both the paying Client and the person being tested must be 18 or over.

2. Service Description

DeceptionDetection.co.uk provides professional truth verification services using EEG (electroencephalography) brain-response testing based on the P300 recognition paradigm.

2.1 Available Services

  • P300 EEG Testing: Brain-response monitoring conducted to a documented, standardised protocol
  • Corporate Investigation Services: Employee screening and fraud investigation (see Section 2.4)
  • Legal Support Services: Written reports and expert commentary that may assist legal matters, subject to the limitations in Section 7.2
  • Private Testing Services: Confidential personal matter investigation
  • Emergency Response Services: Same-day and next-day urgent testing, subject to examiner availability

2.2 Service Standards

All testing is conducted by trained examiners using professional EEG equipment operated to a documented protocol in controlled environments. We maintain the highest standards of professionalism and confidentiality.

2.3 Accuracy Statements

No truth verification method — EEG-based, polygraph, or otherwise — is infallible. Results represent the examiner's professional interpretation of measured physiological responses under the test protocol. They are probabilistic in nature, false positives and false negatives can occur, and results should always be considered alongside other evidence and professional judgment. We make no guarantee as to any particular outcome or level of accuracy in any individual case.

2.4 Corporate & Employer Bookings

Where testing is commissioned by a business in relation to employees, contractors, or job applicants, the commissioning business warrants that: (a) participation by each person tested is genuinely voluntary; (b) it has taken its own legal advice on the use of truth verification testing in an employment context; and (c) it will not treat a refusal to be tested, or any test result, as the sole basis for disciplinary or employment decisions. The Company accepts no liability for employment-related claims arising from the commissioning business's use of our services or results.

3. Booking & Scheduling

3.1 Booking Process

Services must be booked in advance through our official channels:

  • Online booking system at DeceptionDetection.co.uk
  • Telephone booking: +44 161 524 5513
  • Email booking: info@deceptiondetection.co.uk
  • Emergency bookings: +44 161 524 5513 (same-day and next-day, subject to availability)

3.2 Booking Requirements

All bookings require the following information:

  • Full legal name and contact details
  • Preferred testing date and time
  • Service type required (EEG)
  • Testing location preference
  • Brief description of testing purpose
  • Any medical conditions or medications
  • Emergency contact information

3.3 Booking Confirmation

Bookings are confirmed only upon receipt of payment. Confirmation includes testing details, location, and preparation instructions.

3.4 Scheduling Changes

Schedule changes must be requested at least 48 hours before the appointment. Subject to availability and may incur additional charges.

3.5 Arrival Times, Travel Delays & Appointment Window

As a mobile service, our examiner travels to your chosen location, and quoted appointment times are estimated start times rather than guarantees. Please allow up to one to two hours either side of your scheduled time to account for traffic, parking, public transport, or other travel delays. We will keep you updated by phone or text message if we are running behind schedule.

Where a delay is significant and the appointment cannot reasonably proceed on the day, we may need to reschedule. In that event we will offer you the next available date at the earliest opportunity and at no additional cost to you. The remedies that apply where we are unable to attend a scheduled appointment due to travel or transport delays are set out in Section 8.5.

To accommodate travel and client availability, appointments may be scheduled up to 11:00 pm by prior arrangement.

4. Payment Terms

4.1 Service Pricing

  • P300 EEG Testing: from £499; corporate and international packages up to £7,000 as listed on our booking page
  • Emergency Services: Premium rates apply

4.2 Payment Schedule

A booking is not confirmed until payment has been received. Where your appointment date is 48 hours or more after the time of booking, our online booking system offers two options and shows the price of each before you pay:

  • Pay in full at the time of booking. This is the lower price. Nothing further is payable.
  • Pay a deposit at the time of booking, with the balance due 24 hours before your appointment. The total price under this option is £50 higher than the pay-in-full price, and the applicable deposit and balance figures are displayed at checkout before payment is taken.

Where your appointment is less than 48 hours after booking, including same-day, next-day and emergency appointments, payment in full at the time of booking is required and the deposit option is not available.

Under the deposit option the balance must be received before your appointment. If the balance is not settled by the time of your appointment we may treat the booking as cancelled by you and release the slot, and Section 8.8 will apply. We will contact you by text message before that happens.

4.3 Accepted Payment Methods

  • Credit/debit cards (Visa, Mastercard, Amex)
  • Bank transfer
  • Stripe payment link for online payments

Please note: we do not accept cash payments.

4.4 Late Payment

Late payments incur a charge of 2% per month. Services may be suspended for accounts more than 30 days overdue.

5. Testing Locations

5.1 Available Location Options

5.1.1 Client Premises

We can conduct testing at your home, office, or business premises, subject to suitability assessment:

  • Quiet, private room with minimal interruptions
  • Adequate lighting and electrical access
  • Climate-controlled environment (18-24°C)
  • Secure parking for equipment vehicle
  • No additional charge within 25-mile radius of major cities

5.1.2 Business Park Locations

Professional meeting rooms at established business parks:

  • Pre-approved facilities in major UK cities
  • Professional environment with privacy
  • Modern facilities with necessary amenities
  • Convenient parking and accessibility
  • Room hire costs included in service fee

5.1.3 Hotel Conference Facilities

Executive meeting rooms at quality hotels:

  • 4-star and above hotel properties
  • Private conference and meeting rooms
  • Professional business environment
  • Catering facilities available if required
  • Overnight accommodation can be arranged

5.1.4 Coverage & Professional Testing Centers

We provide professional EEG testing with full UK coverage, dedicated international locations, and worldwide bookings available on request.

  • United Kingdom: Full nationwide coverage, including London, Birmingham, Manchester, Edinburgh and Somerset
  • International locations (by prior consultation): Ireland, Switzerland, USA, Canada, Singapore, UAE, and Hong Kong
  • Worldwide: Bookings outside the locations listed above can be arranged on request
  • Purpose-built testing facilities in major UK cities
  • Specially designed testing environments
  • State-of-the-art equipment and facilities
  • Maximum privacy and confidentiality
  • Waiting areas for accompanying persons

5.1.5 Same-Day & Short-Notice Bookings

For same-day, emergency, or short-notice bookings where a dedicated meeting room cannot be pre-arranged, testing may be conducted in a suitable alternative venue such as:

  • A quiet area within a hotel lobby or lounge
  • A hotel guest room booked for daytime use
  • A café or lounge with adequate privacy

Our portable P300 EEG equipment is laptop-based and does not require a dedicated room. While we always aim to secure the most private setting available, clients booking at short notice acknowledge that the testing environment may differ from a pre-booked conference or meeting room. If you require a guaranteed private room, we recommend booking at least 48 hours in advance.

5.2 Location Requirements

All testing locations must meet minimum standards:

  • Private, secure environment
  • Free from interruptions and distractions
  • Adequate space for equipment setup
  • Stable electrical supply
  • Emergency access for medical situations

5.3 Travel and Setup

Our technicians arrive 30-60 minutes before testing for equipment setup and environment preparation. Travel time and setup are included in service pricing within agreed radius.

5.4 Home Visit Staffing & Conduct

Truth verification testing can involve sensitive personal matters, and results are sometimes received in emotionally charged circumstances. For the protection of both our clients and our staff, home visits are normally attended by two members of staff. This is standard safeguarding practice: it ensures the session is professionally witnessed, protects all parties present, and allows testing to proceed safely in private residences.

5.4.1 Zero Tolerance of Abuse

We operate a strict zero-tolerance policy towards violence, threats, intimidation, or verbal abuse directed at our staff by any person present at the testing location. If such conduct occurs, our examiners will withdraw from the property immediately and the test will be terminated. Where appropriate, incidents may be reported to the police. A test terminated for this reason is treated as a completed appointment and no refund, credit, or free rebooking will be provided — see Section 8.6 and our refund policy in Section 8.

5.4.2 Staffing Availability

In the rare event that we are unable to provide two members of staff for a scheduled home visit, we will contact you as early as possible and offer, at no additional cost, either: (a) rescheduling of the home visit to the next mutually convenient date, or (b) an appointment at a suitable professional venue local to you (see Sections 5.1.2 and 5.1.3). If we are unable to offer either alternative within a reasonable period, the appointment will be treated as a company cancellation and the remedies in Section 8.2 will apply. This section does not affect your statutory rights under the Consumer Rights Act 2015.

6. Client Preparation

6.1 Pre-Test Requirements

To ensure accurate results, clients must:

  • Get adequate sleep (minimum 6 hours) before testing
  • Avoid alcohol for 24 hours before testing
  • Avoid recreational drugs for 72 hours before testing
  • Eat a light meal 2-3 hours before testing
  • Arrive 15 minutes early for check-in
  • Bring valid photo identification
  • Wear comfortable, loose-fitting clothing

6.2 Medical Disclosures

Clients must disclose:

  • All current medications and supplements
  • Medical conditions affecting heart rate or blood pressure
  • Neurological conditions or brain injuries
  • Mental health conditions or treatments
  • Pregnancy status
  • Recent illnesses or infections

6.3 Contraindications

Testing may not be suitable for individuals with:

  • Severe cardiovascular conditions
  • Uncontrolled epilepsy or seizure disorders
  • Severe mental health conditions
  • Active substance abuse
  • Cognitive impairments affecting comprehension

Health & Safety

Testing will be postponed if the client appears unwell, intoxicated, or unable to provide informed consent. Your safety is our priority.

6.4 Consent of the Person Being Tested

The person being tested is often not the person who booked and paid for the service. Regardless of who pays, testing will only proceed with the free, informed consent of the person being tested, given in person before the test begins. The test subject may decline to be tested, or withdraw at any point during the session, without giving a reason. Our examiners will not test anyone who appears to have been pressured, coerced, or misled into attending.

Where a test does not proceed, or is stopped, because the test subject declines or withdraws consent, this is not a cancellation by the Company. The appointment will be treated as delivered and the booking remains non-refundable under Section 8.1, as our costs of scheduling, travel, and attendance have already been incurred.

7. Service Limitations

7.1 Accuracy Limitations

No truth verification method is infallible:

  • Results reflect measured physiological responses interpreted under a standardised protocol, not a direct reading of truth or lies
  • Results may be affected by medical conditions, medication, fatigue, or the conduct of the person tested
  • False positives and false negatives can occur
  • Results should be considered alongside other evidence
  • No specific accuracy rate is guaranteed for any individual test

7.2 Legal Limitations

Our services are subject to legal restrictions:

  • Cannot be used to compel self-incrimination
  • Court admissibility varies by jurisdiction
  • Not accepted by all legal systems
  • Professional legal advice recommended
  • Results may not be definitive legal proof

7.3 Scope Limitations

Our services are limited to:

  • Specific factual questions only
  • Recent events (within 2 years for best accuracy)
  • Questions the subject can clearly understand
  • Matters within the subject's direct knowledge
  • Non-medical diagnostic purposes

7.4 What We Cannot Do

  • Predict future behavior or intentions
  • Diagnose medical or psychological conditions
  • Test anyone under the age of 18
  • Guarantee specific legal outcomes
  • Override other forms of evidence

7.5 Results: Status and Delivery

Results are normally delivered to the Client as a written report or certificate within 2 hours of the test, unless otherwise agreed. Results constitute the examiner's professional opinion based on the physiological data recorded during the session. They are not a determination of fact, a finding of guilt or innocence, or a legal judgment, and must not be represented as such. Verbal indications given on the day, if any, are provisional and are superseded by the written report.

7.6 Use of Results by Clients

Results are provided for the Client's private and personal purposes. The Client is solely responsible for any decision made, action taken, or statement published on the basis of a result. We strongly advise against publishing or broadcasting test results or characterisations of another person's result (including on social media). The Company accepts no liability for any loss, claim, or dispute — including defamation claims — arising from the Client's use, disclosure, or publication of results.

8. Cancellation & Refund Policy

8.1 Client Cancellations

Except as set out in Sections 8.2, 8.5 and 8.7, and subject to your statutory rights, bookings are non-refundable once confirmed and payment has been processed. When you book, we immediately begin incurring real costs on your behalf — examiner scheduling, travel arrangements, venue hire, and where necessary hotel accommodation — which is why cancellations at short notice cannot be refunded. By completing a booking you acknowledge and accept that:

  • Cancellations and no-shows: No refund is issued for cancellations (including same-day and day-before cancellations), changes of mind, or failure to attend
  • Rescheduling: Subject to availability and at our sole discretion (see Section 8.3)
  • Termination for conduct: A test terminated due to abusive, threatening, or violent behaviour is treated as a completed appointment with no refund or credit (see Sections 5.4 and 8.6)
  • Subject withdrawal: A test that does not proceed because the person being tested declines or withdraws consent is treated as delivered (see Section 6.4)
  • Deposit bookings: Where a booking was made on the deposit option in Section 4.2, cancellation and unpaid balances are dealt with in Section 8.8

Important: Cancellation & Refund Policy

Once a booking is confirmed, refunds are only available where these terms or your statutory rights provide for one (see Sections 8.2, 8.5 and 8.7). Refunds are not available for cancellations at short notice, no-shows, dissatisfaction with results, or changes in personal circumstances. By proceeding with payment you confirm that you have read and accept this policy, and that the charge to your card is authorised by you. If you have any concern about a payment, please contact us first — we keep full records of every booking, acknowledgment, and communication, and we respond to all payment disputes with that evidence.

8.2 Company Cancellations

If we must cancel due to:

  • Equipment failure: Full credit and priority rebooking at no additional cost
  • Examiner illness or staffing shortfall: Reschedule to the next mutually convenient date, or an appointment at a suitable professional venue local to you, at no additional cost (see Section 5.4.2)
  • Force majeure: Full credit held on account and priority rebooking once the event has passed
  • Safety concerns identified by us prior to testing (e.g. unsuitable premises): Full credit and explanation provided. This does not apply where a test is terminated due to the conduct of the client or persons present — see Section 8.6
  • Travel or transport delays: handled under Section 8.5 below

Where we offer a reasonable alternative appointment date or venue under this section and the offer is declined, the booking will be treated as a client cancellation under Section 8.1 and no refund or credit will be due. This section does not affect your statutory rights under the Consumer Rights Act 2015.

8.3 Rescheduling

Rescheduling requests must be made at least 48 hours in advance. One free reschedule per booking; subsequent changes incur £50 administration fee.

8.4 Refund Policy

Refunds are available only as set out in these terms: where we cancel and cannot offer a reasonable alternative (Section 8.2), where we miss two appointments through travel delays (Section 8.5), or where the statutory cooling-off period applies (Section 8.7). In all other cases sales are final once a booking has been confirmed and payment processed. Nothing in this section affects your statutory rights under the Consumer Rights Act 2015.

8.5 Travel Delays & Missed Appointments

Because our examiner travels to your location, appointments can occasionally be affected by travel or transport delays outside our reasonable control. Where this happens, the following remedies apply to that booking:

  • First missed appointment: If we are unable to attend your scheduled appointment due to a travel or transport delay, you will not be charged again and we will offer you the next available date at the earliest opportunity, at no additional cost.
  • Second missed appointment: If we are subsequently unable to attend the rescheduled appointment for the same booking due to a further travel or transport delay, you will be entitled to a full refund of all payments made for that booking.

This section applies only to appointments missed by us as a result of travel or transport delays and does not affect your statutory rights under the Consumer Rights Act 2015.

8.6 Termination for Abusive or Threatening Conduct

As set out in Section 5.4, we operate a zero-tolerance policy towards violence, threats, intimidation, or abuse directed at our staff. If our examiners terminate a test and withdraw from a location for this reason:

  • The appointment is treated as completed and delivered in full
  • No refund, credit, or free rebooking will be provided
  • Any partial results obtained before termination may, at our discretion, not be released
  • We reserve the right to decline future bookings from the individuals involved
  • Serious incidents may be reported to the police

Our staff attend your property in a professional capacity to deliver a service you have requested. This policy exists to keep them safe and applies to the conduct of everyone present at the testing location, not only the person being tested.

8.7 Online Bookings & Your 14-Day Cooling-Off Right

Bookings made online or by telephone are distance contracts under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, which normally give consumers 14 days from the date of booking to cancel.

Appointments 14 or more days after booking: If your appointment date is 14 days or more after the date you book, you may cancel within 14 days of booking for a full refund, provided the appointment has not yet taken place and we have not, at your request, already incurred non-recoverable costs specific to your booking (such as flights for international appointments, which will be deducted). After the 14-day period ends, Section 8.1 applies and the booking is non-refundable.

Appointments within 14 days of booking (including same-day and next-day): By choosing an appointment date within 14 days of booking, you expressly request that we begin performing the service within the cooling-off period. Performance begins immediately upon confirmation — scheduling the examiner, arranging travel and, where required, accommodation and venue hire. You acknowledge that once the service has been performed (your appointment date has been attended or held for you), the right to cancel is lost, and that if you cancel before the appointment, we are entitled to retain payment reflecting the costs incurred and the work done, which for short-notice bookings will typically be the full booking fee.

This section is intended to reflect, not restrict, your statutory rights.

8.8 Deposit Bookings & Unpaid Balances

Where you have booked under the deposit option in Section 4.2, the following applies in addition to the rest of this Section 8.

  • The deposit secures the appointment. On receipt of the deposit we schedule the examiner and begin arranging travel and, where required, accommodation and venue hire for your date.
  • Balance due 24 hours before. We send a secure payment link by text message and email. The balance may also be taken from the card used for the deposit, which you authorise at checkout for that purpose.
  • If the balance is not paid we may cancel the appointment and release the slot. The deposit is then treated as a client cancellation under Section 8.1 and is retained to the extent of the costs we have already incurred and the work already done for your booking.
  • If you cancel a deposit booking the deposit is retained on the same basis. Any balance already paid, over and above those costs, is refunded.
  • Rescheduling is available under Section 8.3 and carries the deposit across to the new date.

Nothing in this section removes the cooling-off right described in Section 8.7, or your statutory rights under the Consumer Rights Act 2015. Where a deposit booking is cancelled within a period in which those rights apply, we will retain no more than the amount those rights permit.
