Why Choose British Manufactured GRP Water Tanks?

British approved GRP tanks have several advantages over the competition.

For starters, they’re manufactured according to stringent UK British standards. The British Standards Institute was the first of its kind worldwide. It has continuously upgraded and refined its criteria to become one of the most trusted approval certifications on an international scale.

These criteria, namely BSI/ISO9001 and WRAS approval, are important when considering a new water storage tank supplier. This is especially true in the case of potable water storage tanks.

When buying from a local supplier, traceability is key concerning the origin of materials and goods. It’s important to research the sustainability and ethics of manufacturers’ production methods beforehand.

One of the major benefits of buying from a local supplier is shorter lead times and convenient access to backup service and support. Our team at Nicholson Plastics is always on hand to answer questions and offer assistance.

Once the tank’s installed, a local company has experts on hand to conduct all the necessary inspections. They can also sign off any required documentation to ensure it complies with regulations.

UK manufacturers offer backup and after-sales service throughout the UK. Local company representatives are available for support and site visits. Supporting UK manufacturing has a wealth of benefits to the consumer but also makes economic and practical sense by ensuring ongoing prosperity for the British economy.

Finding a Reputable GRP Water Tank Supplier 

Choosing a reputable and reliable supplier is your first priority when it comes to water tanks. Always purchase tanks from certified manufacturers in compliance with all local and national regulations. Have your tank put in by a company whose installation teams are certified, trained, and experienced.

Advantages of Choosing GRP Over Alternative Materials


GRP VS Concrete & Steel

GRP (glass-reinforced plastic) otherwise known as fibreglass, has several advantages over other materials used to manufacture water tanks. It outperforms materials like steel and concrete in every test and offers a series of lasting benefits, including:

Lightweight, Strong and Durable

GRP’s is a lightweight material when compared to steel or concrete. GRP tanks suit a variety of installations due to their lightweight capabilities and weather-resistant properties. GRP water tanks are installed all over the world and perform even in the harshest of environments.

A high glass to resin ratio ensures superior durability and strength without the drawback of excessive weight. Steel relies on weight to achieve strength. Aluminium, while lightweight, offers low strength capabilities. GRP outperforms competitor materials for strength and durability making it a cost-effective solution for all industry sectors.

Corrosion-Resistant and Cost-Effective

All metals corrode over time unless subjected to costly anti-rust treatments. GRP’s weather-resistant and rust-free by nature, which means fewer maintenance costs and long useful life.

A GRP water tank can last for up to 25 years without any additional care.

Due to its lightweight properties, GRP material is cheaper to transport. It rarely requires heavy lifting equipment to on/offload. It’s easily manoeuvrable which reduces installation costs significantly.

Convenient Designs/moulding

GRP’s easy to work with, so manufacturers can assist with a wide range of solutions for industrial, agricultural, and residential applications.

This flexibility makes it easier to find a cold water tank to meet the necessary design and capacity criteria for numerous projects.
