Unvented Cylinder Installation in Camberley
Mains-pressure hot water on every tap, no more loft tanks, and the airing cupboard reclaimed — that's what an unvented cylinder gets you in Camberley. We're G3 qualified (the specific certification for unvented systems, distinct from Gas Safe) and fit Megaflo, Telford and Joule cylinders weekly across GU15. The switch typically takes 2 days and includes the safety commissioning and Building Regulations notification.
Why this matters in Camberley (GU15)
Bigger Camberley homes — particularly large family detached around Heatherside — often outgrow a combi's hot water flow when a second bathroom or en-suite goes in. An unvented cylinder is usually the right answer at that point: strong flow to two showers running simultaneously, no drop-off, no tank in the loft.

Unvented cylinder installation FAQs for Camberley
What size unvented cylinder do I need in Camberley?+
Rule of thumb: 45L per person plus 50L for the bath. A 3-bed large family detached around Heatherside with 2 bathrooms typically needs 180-210L; a 4-5 bed home with 3 bathrooms needs 250-300L. We size at survey based on your actual usage, not a formula.
Do I need a system boiler with an unvented cylinder in Camberley?+
Almost always yes — a system boiler and unvented cylinder are the standard modern pairing. A combi + unvented cylinder is unusual and rarely worth the complexity. If you're on a combi and upgrading to unvented, budget for a boiler swap too.
How much does an unvented cylinder install cost in Camberley?+
Cylinder-only replacement (existing unvented): £1,895-£2,495. Vented-to-unvented conversion including loft tank removal: £2,495-£3,195. Full system boiler + unvented + rad upgrades: £6,500-£9,500.
Where does the discharge pipe run for a Camberley unvented cylinder?+
To a safe outside location — usually the side of the house or into an internal drain via a tundish. Compliant with G3 and building regulations. We plan the route at survey and confirm with Surrey Heath Borough Council where required.
Which brand of unvented cylinder do you fit in Camberley?+
Megaflo Eco (Heatrae Sadia) for most installs — proven, well-supported, easy to service. Telford Tempest for stainless-steel-preferred customers, and Joule for solar-thermal-ready installs. All come with 25-year cylinder warranties.
