Rend Master Ltd, Common Questions
Is Rend Master Ltd SEAI-registered?

Contact Rend Master Ltd directly using the phone number on this page. Nothing goes through us, there is no booking fee, and your details are not passed to anyone else or sold on.
What areas does Rend Master Ltd cover?
Rend Master Ltd is based in Mayo and takes work across the county, including Castlebar, Westport, Ballina, Claremorris, Knock, Belmullet, Crossmolina and Swinford. Most installers cover their whole county rather than one town, so it is worth confirming your own address when you call.
Does my home in Mayo qualify for a grant?
A home built and occupied before 2021 usually qualifies. Housing across Mayo varies a lot, so the survey decides rather than the county. A registered installer confirms eligibility during a free survey before anything is committed.
Do I need to use an installer based in Mayo?
No. SEAI registration is national rather than county by county, so a contractor listed under a neighbouring county can quote for your home and handle the grant the same way. Getting two or three quotes is the only reliable way to see what the work should cost.
Does Rend Master Ltd only do heat pump installation?
On the SEAI register they are listed for heat pump installation. They may well do other work, but heat pump installation is the measure their registration covers, so it is the one they can process a grant for.
