Frequently asked questions
Is the free estimate really free?
Yes. No signup, no email, no card: enter your project and the full trade-by-trade breakdown is there on screen. You can save it as a PDF too, without an account.
Is the first quote check really free?
Yes, and no card is needed. Signed in, you get one free check on your account. Anonymously, you get one free check per browser session. After that a project is £10, paid once.
What do I get for £10?
The comparison between the quotes on your project: every quote on the same basis, what each one leaves out, where the scope differs, the regulation traps, and the questions to ask each builder before you sign. That is how you see which quote is genuinely cheaper. You also get the full report, the PDF and the letter to send your builder. One payment covers the whole project.
Do I need a subscription?
No. £10 is a one-off payment per project, and the comparison is part of it rather than an add-on. Pay again only when you have a new project to analyse.
How is this different from other cost calculators?
Most calculators give a single number. MyBuildAlly breaks costs down by up to 14 trades, adjusts for your exact region, compares procurement routes, and puts your actual builder quotes on the same basis so you can see what each one leaves out.
How many quotes can I upload per project?
Up to six, and uploading them is free. Six is the most a comparison can read clearly. Reading what each quote says costs nothing; £10 unlocks the comparison between them and the full report.
Do you sell my data to builders?
No. We don't sell leads, share your details with contractors, or monetise your data in any way.
