LPG Tanks (Types, Safety, Access)

Types of LPG tank

Domestic LPG tanks are typically propane and come in a few common formats. Your choice usually depends on space, aesthetics, ground conditions, and delivery access.

Above-ground LPG tanks

Above-ground tanks are the most common option for homes. They’re installed on a prepared base and are relatively quick to fit. They’re also easier to inspect and maintain because all components are visible.

• Pros: simpler installation, easier servicing, often lower install cost
• Cons: visible in the garden, may need screening (fencing/planting) depending on location

Underground (below-ground) LPG tanks

Below-ground tanks sit in an excavation with only the dome/lid visible at ground level. They’re popular where appearance matters or space is tight, but installation is more involved.

• Pros: discreet, can suit landscaped gardens, less visually intrusive
• Cons: higher install cost, groundworks required, drainage/groundwater considerations

Metered estates / shared systems

Some homes are supplied via a metered LPG network (often on estates or park homes) where a central tank feeds multiple properties. Your switching options and contract structure can differ from single-home bulk tanks.

Common tank sizes and how to choose

Tank size is normally matched to your annual usage and how frequently you want deliveries. A larger tank can reduce how often a tanker needs to visit, but siting and space matter.

• Smaller households or cooking-only setups may suit a smaller tank or cylinders.
• Typical family homes using LPG for central heating often need a mid-sized bulk tank.
• Larger properties or high hot-water demand may benefit from a larger tank to avoid frequent top-ups.

Your supplier will usually recommend a size after reviewing property details, appliance load, and estimated annual consumption.

LPG tank safety: what homeowners should know

LPG tanks are designed with multiple safety systems and are subject to strict standards. The biggest safety factors for homeowners are correct siting, keeping the area clear, and allowing inspections.

Keep the tank area clear

• Don’t store combustibles near the tank (timber, fuel, sheds, waste bins).
• Keep shrubs and hedges trimmed so valves and labels remain visible.
• Don’t box in the tank or create enclosed spaces around it.

Ventilation and gas behaviour

LPG is heavier than air. If there’s ever a leak, gas can collect in low areas (pits, drains, basements). That’s why siting, ventilation and sensible landscaping around the tank are important.

Inspections and maintenance

Suppliers typically carry out periodic safety checks and may require access for inspection, maintenance, or component replacement. If anything looks damaged (pipework, regulators, protective covers), report it rather than attempting DIY repairs.

Access requirements: deliveries, tanker reach, and practical siting

A well-sited LPG tank isn’t just about where it looks best—it must also be deliverable and serviceable. Delivery tankers use hoses to fill your tank, so the supplier will assess:

Tanker access to your property

• Road/drive width and turning space (especially for narrow lanes)
• Weight limits, soft verges, steep gradients, or tight bends
• Overhead clearance (trees, cables, low arches)
• Winter access (ice, mud, restricted farm tracks)

Hose distance and safe filling position

The tanker must be able to park in a safe place and run a hose to the tank. Long hose runs can be limiting, and access can be affected by gates, walls, planting, or changes in levels.

Ongoing access for inspections

Even if delivery works, you also need safe access for periodic inspections and maintenance. Avoid siting tanks behind locked structures or in areas that become blocked by garden changes over time.

Where can an LPG tank be installed?

Tank location is assessed against safety separation distances and practical access. The supplier will normally carry out a site survey and confirm an approved position.

• Above-ground tanks are often placed on a stable base with clear space around them.
• Below-ground tanks need suitable ground conditions and careful planning for drainage and groundwater.
• Boundaries and buildings may limit where a tank can go, depending on required clearances.

If you’re planning landscaping, decking, fencing, or a new outbuilding, consider the tank location first so you don’t accidentally compromise safety distances or block delivery access later.

Do you need planning permission for an LPG tank?

Many domestic installations are handled as part of a supplier’s normal installation process, but requirements can vary depending on property type, conservation areas, listed buildings, and how the tank is sited. Your installer/supplier should advise if anything additional is needed.

Homeowner checklist for LPG tank safety and access

• Keep the tank area tidy and free from stored items.
• Maintain clear access for delivery and inspection.
• Trim vegetation and don’t enclose the tank.
• Don’t alter pipework, valves, or regulators yourself.
• Before building decking/fences/sheds, check you won’t block access or reduce clearances.
• Know who your supplier is and how to contact them in an emergency.

FAQs

Is an underground LPG tank safer than an above-ground tank?

Both can be safe when installed correctly. The key factor is correct siting, clearances, and compliance with supplier guidance. Underground tanks are more discreet, while above-ground tanks are easier to inspect visually.

Can I move my LPG tank?

Tank relocation should be handled by the supplier or an approved specialist. Moving a tank can involve new groundworks, pipework, and safety checks—don’t attempt this as a DIY job.

What happens if my driveway is too narrow for a tanker?

Suppliers will assess access during a site survey. If access is difficult, they may recommend an alternative tank position, a different delivery approach, or advise whether the property is suitable for bulk LPG.
