How Much Does a Lie Detector Test at Home Cost?

    From £799 for a single issue examination and from £1199 for a couples test, all inclusive. That is the whole answer, and the rest of this page explains what all inclusive actually means, why the soonest visits cost more, and how to read the cheaper numbers you will see elsewhere.

    What the price includes

    One figure covers the visit end to end. Before you pay a penny, the booking page shows every available time for your exact postcode with its exact price attached. That number includes:

    The examiner travelling to your address, anywhere in coverage

    The pre-test interview and question formulation

    The examination itself on computerised instrumentation

    The full written report with your recorded charts, within 24 hours

    No call-out fee, no mileage, no report sold separately, no balance collected on the day. Payment in full online is what confirms the visit instantly, and Klarna pay-in-3 is available at checkout.

    Why the soonest visits cost more

    The soonest visits cost more because the diary bends around one address at short notice, while dates further ahead settle to the base price. The difference is never a surprise: it is already inside the price printed on each time before you choose it, so an urgent Tuesday simply shows a different number from a leisurely Friday, and both are final.

    How to read a cheap “from” price

    Some providers advertise home testing from figures several hundred pounds below ours. Read the small print before comparing, because a low headline has a habit of growing on its way to your door.

    The pattern is consistent across the industry. A non-refundable deposit of £125 to £150 is taken first, often before a date is even confirmed, and stays gone if the arrangement falls through. Travel to your location is then charged on top, priced per visit once they know where you are. Short notice attracts its own surcharge, quoted after enquiry rather than shown up front. Sometimes the written report is an extra line again. By the time the examiner is at your table, the from price is a memory.

    None of this is illegal; it is simply a pricing style, and it relies on you being too far into the process to turn back. Our answer to it is structural rather than rhetorical: the price on the slot is the price, every component included, shown before any money changes hands. If you are comparing us against a cheaper number, the only fair comparison is that final figure against ours.

    The honest cheaper option

    If you can travel easily, our own office network is the legitimate saving: six offices across the South, Wales and London running the identical examination for less, with the same instant booking. The home visit premium buys the travel, the exclusivity of the diary and the privacy of your own front room. When those matter, it is money well spent; when they do not, take the office and keep the difference.

    Cost questions, answered

    How much does a lie detector test at home cost in the UK?

    With us, from £799 for a single issue examination and from £1199 for a couples test, all inclusive of travel, the examination and the full written report with charts. The exact price of every available visit time is shown before you book, and nothing is added afterwards.

    Why do same-day and next-day visits cost more?

    Because urgency has a real cost: the diary is rearranged around one address at short notice. Prices vary with how soon the visit is, the exact price of every available time is shown before you choose it, and dates further ahead settle to the base price.

    Are there any extra charges, travel fees or call-out costs?

    No. The figure attached to the time you pick is the whole figure: travel anywhere in our coverage, the pre-test interview, the examination and the written report with the recorded charts. The only optional extra is expert witness testimony for legal proceedings, quoted separately if you ever need it.

    Is a cheaper office test available?

    Yes. Our network runs six offices across the South, Wales and London, and the same examination costs less at any of them because nobody has to travel to you. If getting to an office is easy, it is the sensible choice. The home visit exists for every situation where it is not.
