Is an LPG Tank Worth the Cost?

What is an LPG Tank? An LPG Tank is a high-pressure container that compresses gas which is used as fuel. They are mainly used if there are no gas mains where you live, so you need an alternative option to heat up your home.

Having an LPG tank can work out to be a smart investment in the long run. While the upfront installation costs can be significant, many households find that the savings on energy bills soon start to balance things out.

Over time, the reduced need for other, often more expensive, energy sources means the system can more than pay for itself.

If you are unsure whether you want to get an LPG tank or not, you can talk to a professional near you on MyBuilder. Simply post your job, and then someone will be back in touch with advice and guidance.

LPG Tank Average Cost

The average cost of installing an LPG tank can vary widely depending on the size and type of tank you need, the amount of site preparation needed, labour charges, and extra equipment.

On average, the tank itself costs between £700 and £1,500, with above-ground models being cheaper than underground options.

Site preparation can add £200 to £500 for an above-ground base or £500 to £1,000 for underground excavation and drainage.

Hiring a tradesperson for the installation costs about £300 to £500, with an additional £200 to £500 for pipework, valves, and safety fittings to connect the tank safely.

Above-Ground vs Underground LPG Tank Cost

Above-ground and underground LPG tanks both have different benefits. An underground tank can be better as it is hidden on your property, however it is more expensive.

We have broken down the costs of above-ground vs underground tanks here:

Above-ground LPG tanks are generally much cheaper to install. The total expense typically ranges between £1,500 and £2,000, which includes the cost of the tank, base, and essential pipework.

Because they don’t require much groundwork, these tanks are usually cheaper to install, making them a budget-friendly choice in comparison to underground tanks.

Underground LPG tanks require additional considerations and expenses due to excavation and groundwork. These costs usually range from £2,500 to £3,500, accounting for factors such as digging, concrete base construction, and necessary reinstatement of the landscape.

Underground tanks do cost more to install, but they’re tucked out of sight, which could be a big plus if you are looking for a cleaner look in your garden.

Step-by-Step Guide to Installing an LPG Tank

Installing an LPG tank requires careful planning and professional expertise to ensure safety and compliance.

Here are the key steps involved:

Step 1: Site Assessment

A tradesperson will inspect your property to determine the most suitable area for your LPG tank.

Step 2: Site Preparation

If your tank is above ground, a stable and level base, such as concrete or paving, is prepared to securely support the tank. If it’s underground, excavation is carried out to create space for the tank and pipework. This may mean excavation costs.

Step 3: Tank Installation

An above-ground tank is positioned directly onto the prepared base and secured in place. Or, an underground tank is carefully lowered into the excavated space and anchored to prevent movement.

Step 4: Connection to Property

The installer connects the LPG tank to your heating or cooking systems using durable pipework. Safety components such as valves and regulators are added to ensure smooth and secure operation.

Step 5: Safety Testing

The system undergoes thorough testing to check for leaks and verify compliance with UK safety regulations. For underground tanks, this step also includes ensuring proper backfilling and tank stability.

Step 6: Final Inspection

A final inspection is conducted to confirm that the installation is complete, safe, and fully operational. The tank is now ready for use.

FAQs About LPG Tank Installation

How often should an LPG tank be serviced?

LPG tanks should be inspected and serviced annually by a qualified technician to ensure they remain safe and efficient. This includes checking for leaks, testing safety components, and inspecting pipework.

What is the lifespan of an LPG tank?

With proper maintenance, an LPG tank can last 20–30 years. Above-ground tanks are typically less exposed to environmental factors, while underground tanks may require more frequent inspections to address potential water damage.

How can you tell if an underground LPG tank has water exposure?

Signs of water exposure in an underground LPG tank include:

• Visible Corrosion: Rust or damage on external parts of the tank.
• Moisture Near Valves: Presence of water or condensation near access points.
• Inspection Findings: Professional inspections may reveal internal or external water damage.
• Fluctuating Pressure: Inconsistent gas pressure could indicate water infiltration.

Regular inspections are crucial for detecting and addressing water exposure early to maintain the tank's safety and performance.

Can LPG tanks be relocated?

Yes, but relocating an LPG tank requires professional assistance. The process involves disconnecting, safely moving the tank, and reconnecting it at the new location, which may incur additional costs.

Are there alternative tank sizes available?

LPG tanks come in various sizes, ranging from 600 litres for smaller homes to 2,000 litres for larger properties or commercial use. Your installer can help you choose the right size based on your energy consumption.
