Frequently Asked Questions

Do you charge for a callout?

Standard callouts within Cork city are included in the quoted job price. Outside the city a €30 callout fee applies and is confirmed before we travel.

How often should a boiler be serviced?

Once a year. Most manufacturer warranties require an annual service by a registered engineer to stay valid.

Are you insured?

Yes — €6.5m public liability cover, and all gas work is carried out by RGI-registered engineers.
