How Costwise makes money
Costwise is free to use. We earn in four ways, and only when you choose to act: a fee if you use a quote partner we introduce you to; occasional affiliate commission on marked links; the price of our optional Renovation Project Pack if you buy it; and a subscription to My Home if you choose one after its free trial. None of them ever changes the prices or advice you see.
Installer quotes (lead generation)
We no longer run a quote form of our own, so we never collect or pass on your details. On 43 guides, the 10 cost calculators for the same jobs, and the driveway costs page, the form on the page belongs to Leads Do Work and you fill in theirs; on the other pages that offer quotes, the button links to Bark and you fill in theirs. If that leads to a job, they may pay us a fee for the introduction. You are never charged, and we never hold your information at any point.
Affiliate links
On a few pages we link to suppliers: a fixed online price for a new boiler, and building materials from Materials Market on our materials calculators and a few do-it-yourself guides. If you buy through one of those links we may earn a commission, at no extra cost to you. Those links are marked, and they never affect our price guides, our quantities or which option we suggest.
Our Renovation Project Pack
We sell the Renovation Project Pack, a £19 set of templates for running a renovation, sold through Whop, which processes the payment. It contains no guide prices, and nothing on this site is written or priced to sell it: every guide, calculator and free download stays free whether or not you buy it.
My Home subscriptions
My Home is our paid notebook for planning and recording work on your home. It is free for 30 days with no card needed, then £4.99 a month or £39 a year if you choose to subscribe, and it never becomes a paid subscription on its own. Payments are processed by Stripe, and My Home has its own terms and privacy notice. It holds no guide prices, and nothing on this site is written or priced to sell it: the guides and calculators stay free and work without an account. Some calculators offer to save your estimate to My Home, beside the quote buttons, never instead of them.
What we do not do
We do not take payment to change a price, rank a supplier higher, or write a fake review. Our figures are independent. Read how we price for the detail.
