Specialist Certification

G3 Unvented Hot Water Systems

Unvented hot water cylinders (such as Megaflo or Telford) must be installed by a G3 certified engineer to comply with Building Regulations. Siroos holds the G3 qualification and can carry out both installation and the required building regulation notification.

This service is increasingly sought after as more homeowners upgrade from traditional vented tanks for better water pressure and efficiency.

G3 Building Regulation notification included
All cylinder brands supplied and installed
Safety valve, expansion vessel, and controls
Full commissioning and handover

Why G3 Certification Matters

Unvented cylinders operate at mains pressure and must be installed correctly. An uncertified installation is illegal, dangerous, and will invalidate your home insurance.

Many plumbers are not G3 qualified — always check before hiring. Siroos is fully certified and registered.

Did you know? Building Regulations Part G requires formal notification to the local authority. We handle this entirely on your behalf.
