Before you buy.
What exactly do I get?
Full how-to access to every phase of the kitchen extension tree — planning, permissions, groundwork, structure, specification, first fix, second fix and completion — plus the cross-cutting tools and materials guides. You can browse the structure for free; the Access Pass unlocks the detailed guidance.
How long does access last?
24 months from purchase — long enough to cover a typical extension from first planning sketch to final sign-off, with room to spare if the build runs long.
Is this a subscription?
No. It is a single one-time payment. There is nothing to cancel and no recurring charge.
Does the price include VAT?
Yes. The price shown is the all-in price you pay, with UK VAT included. Octasoft Ltd is VAT registered (GB 936 2753 06) and your Stripe receipt is a valid VAT receipt.
I've never managed a build before — is this for me?
Yes, that's exactly who it's for. This is about project-managing your extension and your trades, not doing the building yourself. It walks you through the sequence, what to check at each stage, and the questions to ask builders and building control, assuming no prior experience.
Can I get a refund?
Because this is digital content with immediate access, you agree at checkout to start straight away and waive the standard 14-day cancellation right. Your statutory rights for faulty or misdescribed digital content are unaffected. See our terms.
Stop guessing what comes next
A kitchen extension runs into the thousands. For £99, a sequenced guide that keeps the order straight and helps you sidestep costly mistakes is a small part of the picture.
