Frequently asked questions
How will I receive my files?
Once your payment goes through, Etsy emails you a download link, and the files stay in your Etsy account under Purchases. You get one ZIP file. Extract it to a folder on a computer and open READ-ME.txt first.
What software do I need?
Microsoft Excel or Google Sheets for the workbooks, and a PDF reader that can fill in and save forms. The workbooks were tested in both and contain no macros. Use a computer: a phone screen is too small to work in them. In Google Sheets, upload the file to Google Drive, open it and choose File > Save as Google Sheets.
Where do the prices come from?
From the Costwise cost guides I publish at costwiseuk.co.uk. Each line in the Plan sheet names the guide it comes from and the month its prices were last reviewed. They are guide prices, not quotes, and they do not update themselves once you have downloaded the file. A builder who has seen your home will price the real job.
Do the prices allow for where I live?
Yes, by region. Choose London; South East and South West; Midlands and East (the UK average); or North, Scotland and Wales, and every priced line adjusts. These are the same regional factors the Costwise website uses. They are not specific to your town.
Is this a building contract or professional advice?
No. It is an organising tool for your own project records: your plan, quotes, changes, payments, deliveries and handover. It does not include technical design, a building contract or professional certification, and it cannot guarantee savings, dates or the quality of the work.
Can I use it for more than one project?
Yes, for your own projects. Save a fresh copy of the project organiser for each one and keep the original file as a backup. The files are for personal use: please do not resell or share them.
Can I get a refund?
Yes. You can cancel within 14 days of buying for a full refund, even after downloading the files, and you do not need to give a reason. Message the shop on Etsy, or email contact@costwiseuk.co.uk with your Etsy order number.
Does it work for projects outside the UK?
The prices are UK prices in pounds, so the Plan sheet is only useful for UK projects. The tracking sheets, forms and email templates work anywhere, but permissions and legal requirements depend on where you live.
