Getting started
You supply and fit.
We bring the booking together.
Customers choose a boiler and date. Cosy Boiler matches them with an approved business that can supply the package and take the job.
Set up your offer
Choose your boilers, installed prices, extras and coverage. Publish the dates your team can honour once your checks and payment setup are complete.
Take care of the job
Confirmed bookings appear in your workspace. Arrange supply and delivery, fit the boiler and add the required paperwork.
From booking to servicing

Before you join
The important
details.
Who can join?
Gas Safe registered installation businesses with engineers qualified for the boiler work offered. We check the business, engineers, insurance and supporting evidence before enabling gas-work bookings. The app guides you through what to provide.
How are jobs allocated?
We match the selected boiler, postcode and date with approved businesses that can supply the package and have capacity. The lowest qualifying total installed price is selected, with a stable tie-breaker. A booking is confirmed after payment; work isn’t guaranteed.
Who supplies the boiler and takes payment?
Your business is the seller. You supply the agreed boiler and extras, arrange delivery and complete the installation. The customer sees your business before payment. Live payment onboarding will be completed before trading opens.
What does it cost to work with Cosy Boiler?
We’ll confirm commission, payment responsibilities and payout terms before you take live bookings. Those commercial terms aren’t published yet. Paid jobs are not currently enabled.
Can I change my prices and availability?
Manage your packages, work areas and future capacity in the app. Confirmed bookings retain their agreed prices and terms, and capacity changes cannot remove already-booked jobs.
What happens if a credential expires?
The app highlights credentials that need renewing. Affected availability is paused until the required checks are complete. Existing jobs remain visible and require review; they aren’t silently cancelled or moved to another seller.
