About Checkmark Ltd

---

Checkmark is dedicated to helping do it yourself (DIY) installers successfully and legally install their own air-conditioners and heat pumps.

Our service saves you money over a complete install by a contractor, and saves you buying specialist tools, and ensures you can be completely confident in your install.

Checkmark are fully F-gas qualified, meaning we can work on any refrigeration, heat pump or air-conditioning system.

We recognise there are many keen and competent DIY enthusiasts who want to do their own installs, but cannot because of F-gas legislation and the cost of the specialist equipment involved. It is these people that form our core market, although we're happy to take on other work too.

As well as detailing our services, our web-site has a comprehensive information section to aid anyone considering or in the process of installing their own system.

We'd love to hear from you, especially if you have suggestions that could add even more value to our information webpages.
