What we do
About Checkmark’s service for DIY installers of air-con and heat pumps.
Booking Checkmark
Checkmark helps you, as a competent ‘DIY-er’, to achieve a safe, legal and responsible install of an air source heat pump or air conditioner in your home, garden office, workshop or elsewhere.
We do this by connecting, testing, commissioning and certifying a system you have prepared.
This approach helps you:
- Stay legal, because Checkmark carries out all regulated F-gas work.
- Avoid buying specialist install equipment.
- Ensure the system is fully pressure and leak tested.
- Save money compared to a complete system installed by a company.
- As a proud DIYer, achieve the quality of work you demand.
Before you book Checkmark
- Read the information pages of this web-site and elsewhere to make sure a DIY led install is for you.
- Read about what we do during a typical install.
- Check the process, a flowchart which explains how it works.
- Refer to the Pre-book Checklist.
When you’re ready, please get in touch using the booking page. We can then arrange a free, no obligation chat - we find a WhatsApp or FaceTime video call works well.
Other work

It is against the law to work with F gas if you do not have the correct qualifications. You could receive a civil penalty for breaking the law.Checkmark is fully qualified in F-gas handling. We provide a professional commissioning service. You do the preparation and physical mounting of the equipment but must not touch the refrigerant or F-gas connections.
