Terms of Service

AcoustaPLOT Echo is provided by AcoustaPLOT Ltd, a company registered in England and Wales (company number 17389299, registered office 81 Howarth Road, Wimborne, Dorset, BH21 2FG). If our registered office changes, the current address is always shown on the Companies House register. These terms apply whenever you use acoustaplot.com or buy anything through it.

Echo generates an indicative acoustic prediction for a room, using the dimensions and surface information you provide, based on a standard statistical method and IEC 60268-16 for speech clarity. It is a design-stage prediction, not a measured survey and not a certificate of compliance. Where a formal, signed-off figure is required — for planning, building control, or a contractual obligation — that comes from a measured survey to BS EN ISO 3382-2 carried out by a qualified acoustician, not from an Echo report.

Echo's output is only as accurate as the room dimensions and surface information you provide. You're responsible for the accuracy of what you enter; we're responsible for correctly applying the stated method to it.

Prices are shown in the currency you choose. For purchases in GBP, AUD, NZD and EUR, the price shown is the total you pay: local tax (VAT, GST or similar) is already included in it, and nothing is added at checkout. For purchases in USD and CAD, the price shown does not include sales tax or similar taxes. Any tax that applies to your order is calculated at checkout from your location, shown to you as a separate line before you pay, and added to the price shown, so the total you pay will be higher than the price shown where tax applies. Echo is supplied and sold by AcoustaPLOT Ltd. Payments are handled through Stripe Managed Payments, with Sold through Link LLC acting as merchant of record. The merchant of record takes your payment details directly and we never see or store your card number, and works out and remits the tax that applies to your order. AcoustaPLOT Ltd is the author and supplier of the software and reports, and is responsible for them as set out in these terms. AcoustaPLOT Ltd remains responsible for refunds required by law.

For a one-off purchase (an Echo report, or an Echo Studio or Echo Pro one-off for one room), payment is taken when you order. For a subscription, the date we actually take your first payment is later than the date you sign up — see clause 6. Echo Studio's one-off, single-room purchase was briefly not offered between 23 September 2026 and 24 September 2026 — this clause continued to apply throughout to anyone who bought one before or during that gap, and applies to everyone who buys one.

At checkout we ask whether the purchase is for a business or company, or for yourself. If you do not answer, or your answer is unclear, we treat you as a consumer. Your answer does not remove any right you have by law.

An Echo report, a one-off Echo Studio or Echo Pro purchase, a Decision Pack, a Brief Builder and a tool bought for a single project are each digital content: one completed report or analysis for the one room (or room type) you describe, not an ongoing account you keep coming back to edit. Every paid report is checked before it is released to you. Normally this takes minutes. If we hold your report for further checks, we will update you within one working day. If it has not been released within two working days of your payment, we refund you in full automatically. While a report is being held you can cancel your order and be refunded. Before you pay, we ask you to tick a box giving your express consent to us supplying it as soon as it has been released, rather than waiting for the 14-day cancellation period to end, and confirming that you understand you lose your 14-day right to cancel once it has been supplied to you (that is, released to you or downloaded). The box is not pre-ticked, we record what you agreed and when, and we send it back to you in your confirmation email. If you do not tick it, we do not take payment. (Echo Studio's one-off purchase was briefly not sold between 23 and 24 September 2026; this clause governed anyone who bought one before or during that gap, and now applies to everyone again.)

The link to a report you have bought stays available for three years from the date you bought it.

That is the only thing you give up: the no-fault right to change your mind. It does not affect your right to a repair, replacement or refund if what you receive is faulty, not as described, or never delivered — contact us and we'll put it right. Your statutory rights are not affected. If we never supply it, your right to cancel and be refunded in full is unaffected.

Echo Studio and Echo Pro are each licensed per person, not per project or per room. The one-off options (Studio £70, Pro £119) are the exception: each covers one room, once, for the person who buys it. Monthly billing runs on a 3-month minimum term, then continues month-to-month until cancelled; cancelling stops renewal at the end of the billing period you're in. Annual billing (currently offered on Echo Studio) is paid upfront for the year; cancelling stops the next year's renewal but doesn't refund months already paid for within the current year. Reports and analyses already downloaded remain yours regardless of a later cancellation.

What the first payment covers. For Echo Studio: initial three-month minimum: £447, collected on your first payment date (shown to you on the order page before you confirm). This is equivalent to £149 a month. After that initial period, £149 is collected monthly from the date three months after your first payment date until cancelled. (For Echo Pro the figures are £897 and £299: initial three-month minimum: £897, equivalent to £299 a month, then £299 collected monthly until cancelled.) Your access starts when you sign up and nothing is collected until your first payment date, which is 15 days after sign-up. The three-month minimum period starts on your first payment date and ends three months later, and you keep access throughout it. If you cancel during that period in the ordinary way, no further payments are taken after the minimum payment and your access continues to the end of the period, but the minimum payment is not refunded for the rest of it. That does not affect your 14-day right to cancel as a consumer (below), your right to withdraw, or your rights and remedies if the service is faulty or not as described.

When you're actually charged. We take your payment details when you sign up, but we do not take a payment then. Your first payment is taken 15 days after you sign up — we show you the exact date on the order page before you confirm. We will email you a reminder about seven days before your first payment is taken, giving the payment date, the amount and how to cancel. For annual plans we also email you a reminder 15 days before each renewal. At sign-up we show you the payment date, the amount and how to cancel before you confirm. If you want to cancel before your first payment is taken, you can do so at any time in those 15 days and nothing will be charged. You can cancel in your account under Billing and subscription, or on our cancellation page.

Your 14-day right to cancel a subscription. Separately from the contractual terms above, if you are a consumer you have a statutory right to cancel a new subscription within 14 days of taking it out, for any reason. That right is not affected by the 3-month minimum term. Because we don't take your first payment until day 15, cancelling within that 14-day window ordinarily means nothing has been charged yet. Echo Studio and Echo Pro are services, and when you take one out we ask you to confirm that you expressly ask us to start the service during the 14-day period. Because we take nothing until day 15, if you cancel within those 14 days you pay nothing, and we do not ask you for a payment for the service you used in that time. Starting the service does not end your right to cancel within the 14 days, and it does not affect your rights if something is wrong with the service. After the 14 days, cancellation works as set out above (the minimum term, then the end of the billing period). To cancel, use the cancellation page, or email echo-support@acoustaplot.com saying you want to cancel — a sentence is enough, and you do not have to explain why. This right is in addition to any rights you have if something is wrong with the service.

Don't use Echo to generate reports for rooms you don't have the right to measure and describe, misrepresent a report as a measured survey when presenting it to a third party, or attempt to resell access to the service itself.

Each Studio or Pro subscription is licensed to one named person, who can run as many rooms as they need for their own professional work. A one-off Studio or Pro purchase covers one room, once, for the buyer. You must not share your login or licence with anyone else, resell it, or use automated scripts or tools to run rooms in bulk.

A report you've paid for is yours to use, share and present as you need to. The underlying software, the absorption-coefficient database, the methodology implementation and AcoustaPLOT branding remain our property throughout, and are not published.

That does not leave you unable to have our work checked. If a report is being relied on in a dispute, an appeal, or a decision somebody else has to sign off, contact us quoting the report reference and we will go through it with you or with an acoustician you appoint, and confirm in writing whether the figures reproduce from the room description and finishes stated in the report. The absorption-coefficient database and the methodology implementation are not released. Where demonstrated compliance is required, the appropriate check is a measured survey to BS EN ISO 3382-2 by a competent acoustician.

Echo reports are provided as an indicative design-stage prediction. For business customers, to the fullest extent permitted by law, we exclude liability for decisions made in reliance on a report in place of a measured survey where one was genuinely required.

Business customers. You deal with us on the basis that reports inform professional judgement rather than replace a measured survey, and that our total liability to a business customer, in aggregate, is limited to the amount you paid us for the order the claim relates to. Any such limit is subject to the reasonableness test in the Unfair Contract Terms Act 1977.

Consumers. If you are buying as a consumer, we do not cap our liability to you by reference to the price of a report. If we break these terms or fail to use reasonable care and skill, we are responsible for loss or damage you suffer that was a foreseeable result. If a report is faulty, not as described, or never delivered, you are entitled to a repair, replacement or refund, and we will put it right. Nothing here limits your rights under the Consumer Rights Act 2015. If you live outside the United Kingdom, nothing in these terms limits any right you have under the consumer law of your own country either. Where that law gives you more than these terms do, it is your law that applies, not these terms.

Third parties. A report is prepared for the person who ordered it. Nobody else acquires a right to rely on it, or to claim against us in respect of it, unless we have agreed that in writing and a reliance limit has been set in that agreement.

Nothing in these terms excludes liability that cannot lawfully be excluded, including for death, personal injury caused by negligence, or fraud.

We may update these terms from time to time; the version in force is the one published here at the time of your order.

These terms are governed by the law of England and Wales, without prejudice to any mandatory consumer protections that apply in your own country of residence.

If you are a consumer, you may bring proceedings either in the courts of England and Wales or in the courts of the country where you live, and we will bring any proceedings against you only in the courts of the country where you live. If you are a business customer, the courts of England and Wales have exclusive jurisdiction.
