Terms of service
Last updated: 16 September 2026
These terms apply when you use MyBuildAlly, whether you use the free check, the free cost estimator, or pay for a report. Please read them. If you do not agree with them, do not use the service.
1. Who we are
MyBuildAlly is a trading name of My Build Ally Ltd. Registered in England and Wales, company number 17019427. Our correspondence address is 71-75 Shelton Street, London WC2H 9JQ, United Kingdom. You can contact us at [email protected]. In these terms, “we” and “us” means My Build Ally Ltd, and “you” means the person using the service.
2. The service
MyBuildAlly provides:
- The free check. You upload a builder's quote as a PDF, photo or document, and we read it and show you a verdict: a summary of what the quote leaves out, how its total sits against a modelled cost range for the job and region, and the number of findings. Your first project is checked free, with no account and no card: one free check per account once you are signed in, and one per browser session when you are not.
- The £10 unlock. One payment of £10 unlocks one project. It includes the full report on every quote on that project (scope gaps, regulation points, contract details and the questions to ask your builder), the report as a PDF, a letter you can send your builder, and, where the project holds more than one quote, the comparison between them. Up to six quotes can be added to a project, and adding them is free.
- The comparison. Where a project holds more than one quote, the unlocked report sets them side by side: what each one covers and leaves out, and, where we can cost the missing work, what each would come to for the same job.
- The estimator. A free cost estimator that gives a modelled cost range for a project you describe, by type, size, specification and region.
How each part works, and what it does not do, is set out on how the check works.
3. Automated analysis, not professional advice
The analysis is automated
The reading of your document, the findings and the written summaries are produced by automated systems (Claude language models together with deterministic checks written by us). They are not reviewed by a person before you see them. An automated reading can misread a figure, miss an item, or flag something that does not apply to your job. We word findings to how sure we are: a flat statement where the rule is certain, “looks” or “appears” where it is not, and a question for your builder where we are unsure. The fixed checks enforce that grading; a finding the model wrote can overstate, which is one reason to confirm it with your builder.
What the output is not
The report, the verdict, the comparison and the estimate are not a survey, a valuation, a quantity surveyor's report, legal advice, financial advice or a building control decision. The price benchmark is a modelled range built from published cost guides, not a set of real quotes for your property. Only a building control body can decide whether work complies with the Building Regulations.
Which rules we analyse
The regulations we analyse are England's unless a finding says otherwise. Wales, Scotland and Northern Ireland have their own building standards, and a finding may not apply to a property outside England.
Confirm before you act
Always confirm a finding with your builder before you act on it, and, where it matters to the money or the safety of the work, with a suitable professional such as an architect, a structural engineer, a quantity surveyor or your building control body. The service is a second opinion on the document in front of you. It does not replace those people, and it does not visit your property.
4. Paying for a report
The price. The unlock costs £10, including VAT where it applies, paid once per project. There is no subscription and no further charge for adding quotes to that project. Payment is taken by Stripe; we never see your card details.
Immediate delivery. The report is digital content, and we deliver it as soon as your payment completes. By paying, you ask us to start delivery straight away and you acknowledge that, once delivery has started, you lose the 14-day right to cancel that the Consumer Contracts Regulations 2013 would otherwise give you for a purchase made online.
Our seven-day refund promise. If the report is not useful to you, email [email protected] within seven days of paying and we will refund the £10 in full. You do not have to give a reason and there is no form to fill in; telling us the email address you paid with, or sending the project link, helps us find the payment quickly. Refunds go back to the card you paid with.
Your statutory rights. The refund promise is in addition to your rights under the Consumer Rights Act 2015, which requires digital content to be of satisfactory quality, fit for purpose and as described, and a service to be carried out with reasonable care and skill. Nothing in these terms reduces those rights.
5. Your responsibilities and acceptable use
When you use MyBuildAlly, you agree to:
- •Upload only documents you have the right to share with us
- •Give accurate details about your project, so the check is measured against the right job
- •Contribute accurate figures if you share what you paid
- •Use the service for your own project, not to resell the analysis or to run a business on it without our written agreement
- •Keep your account details to yourself, and tell us if you think someone else has used them
You must not:
- Scrape, harvest or bulk-download content or data from the service
- Upload anything unlawful, or anything that is not a genuine document for your own project
- Try to get around the free-check limit, the rate limits or the payment step
- Interfere with the service or try to gain access to another person's project
We may suspend or close access for anyone who breaks these rules. If we do, any report already paid for stays available to you unless the payment itself was fraudulent.
6. Our content and your uploads
Your documents stay yours. You keep all rights in the quotes and other documents you upload. You give us permission to store them, read them with automated systems, and show the results to you, and to keep them so you can reopen your report later. On request we delete your projects and the documents behind them from our storage, as our privacy policy describes.
Anonymised data. We keep anonymised figures from the quotes checked here (the job type, the size, the totals and the postcode district, never your name, address or the document itself) and use them to test and improve the price model, as the privacy policy describes.
Our content. The site, the checklists, the model, the report layouts and the MyBuildAlly name belong to us or our licensors. You may use the reports you have paid for for your own project, including sharing them with your family, your builder or an adviser. You may not republish or sell them.
7. Liability
We provide the service with reasonable care and skill, as the Consumer Rights Act 2015 requires, and we will put right a report that does not meet that standard or refund it.
Beyond that, we are not liable for decisions you take on the analysis: whether to accept a quote, which builder to appoint, what to pay, or whether to seek professional advice. The analysis is automated, it can be wrong, and section 3 tells you to confirm it before you act on it. We are not liable for loss that was not foreseeable when you bought the report, or for business losses, because the service is for homeowners and their own projects.
Nothing in these terms excludes or limits liability that cannot lawfully be excluded or limited, including liability for death or personal injury caused by negligence, for fraud, or under your statutory rights as a consumer.
8. Changes to these terms
We may update these terms from time to time, for example when the product or the law changes. We will post the new terms on this page and change the date at the top. A change does not affect a report you have already paid for. If you keep using the service after a change, the new terms apply to that use.
9. Governing law
These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction over any dispute about them. If you live in Scotland or Northern Ireland, you can also bring a claim in your own courts, and nothing here takes away the protection of the consumer law of the place where you live.
