Derry Bold - White Thermostatic Radiator Valve & Installation Kit Straight 15mm

Bring the key radiator finishing components together in one kit

The Derry Bold White radiator installation kit brings together a thermostatic radiator valve, matching lockshield and coordinated finishing accessories in one purchase. It gives you room-by-room temperature control while helping you complete the visible radiator connection without sourcing each part separately.

Why choose this radiator installation kit?

• Reduce unnecessary heating once the room is comfortable: The TRV automatically adjusts hot-water flow through this radiator as the surrounding room temperature changes.
• Avoid sourcing a separate lockshield: The TRV and matching lockshield are included together, giving you both valve positions as one coordinated set.
• Give the exposed pipework a cleaner finish: A matching pair of pipe covers conceals the visible section of pipe around the radiator connection for a tidier finished installation.
• Help the radiator heat properly after installation: With a bleed valve included, the radiator can be vented when needed to support effective hot-water circulation.
• Finish the remaining radiator port neatly: The matching blanking plug closes the unused radiator connection as part of the same coordinated set.
• Choose a fitting designed around your pipework: Straight valves are appropriate where the pipe route meets the radiator connection without needing a turn.
• Keep the visible installation coordinated: The modern valve shape keeps the radiator connection looking clean and contemporary. The White colour with a gloss finish gives the visible parts of the kit a consistent appearance.
• Choose a valve set backed beyond installation: The included 3 years guarantee adds confidence when choosing a valve set for ongoing everyday use.
