Frequently Asked Questions in Maidstone

How does hard water affect wet heating systems in Maidstone offices?

Hard water rapidly deposits limescale on critical heat exchangers, destroying boiler efficiency. We utilise targeted chemical dosing and magnetic filtration to keep your waterways perfectly clear.

What are the emergency CP12 requirements for Maidstone corporate parks?

All commercial premises must maintain an annual CP12 certificate issued by a Gas Safe engineer. We provide comprehensive on-site inspections to quickly resolve faults and issue your paperwork instantly.
