Types of Pipes and Materials
Choosing the right type of pipe is crucial for any plumbing installation. We work with a variety of pipe materials, each suited to specific needs and applications:
- Copper Pipes: Known for their durability and reliability, copper pipes are ideal for both hot and cold water supply.
- PEX Pipes: Flexible and resistant to scale and chlorine, PEX pipes are perfect for new construction and repiping projects.
- PVC Pipes: Commonly used for drain, waste, and vent systems, PVC pipes are lightweight and easy to install.
- Galvanised Steel Pipes: Typically used for water supply lines, these pipes are strong but can corrode over time.
- CPVC Pipes: Chlorinated PVC pipes are great for hot water applications, offering a higher temperature resistance than standard PVC.
Wall Types and Installation Techniques
Understanding the type of walls in your home is essential for effective plumbing. Whether you have solid brick walls, cavity walls, or plasterboard walls, our team is equipped to handle all installation challenges.
- Solid Brick Walls: We use masonry drill bits and wall anchors to secure pipes and fixtures, ensuring a sturdy installation.
- Cavity Walls: Special care is taken to avoid bridging the cavity, preventing moisture transfer. We use cavity wall fixings and pipe sleeves to protect the plumbing.
- Plasterboard Walls: Lightweight and common in modern homes, plasterboard walls require careful handling. We use wall studs and noggins to provide additional support for heavy fixtures.
We have five tips for moving homes curated for you.

Building Requirements and Regulations
Compliance with building regulations and planning permission requirements аре non-negotiable. We ensure all plumbing work meets the stringent requirements set by local planning departments in London and Essex.
- Building Regulations Part H: Covers drainage and waste disposal. We ensure all systems are correctly installed and vented, preventing any blockages or leaks.
- Building Regulations Part G: Pertains to sanitation, hot water safety, and water efficiency. Our installations are designed to conserve water and maintain safe temperatures.
- Water Supply (Water Fittings) Regulations 1999: Ensures the prevention of waste, misuse, undue consumption, contamination, or erroneous measurement of water supplied by a water company.

Mario Sumsung25/04/2024Trustindex verifies that the original source of the review is Google. I am a builder and I have used this company in the last 7 or 8years and they never let me down. The prices were decent and the services very professionally done. When we had changes in our or clients' plans, we found the middle ground all time. I will keep using them until they prove me is the time to stop. One downside is that they are not willing to travel everywhere I need them, if it is far, like Melksham. If Costin and his team will read this review, they will remember. You can try them out and see for yourself! Remi Okeshola25/04/2024Trustindex verifies that the original source of the review is Google. Excellent job guys. Very clean professional and timely.

Frequently Asked Questions
What permits are required for a house renovation in London and Essex?
Permits depend on the scope of the renovation. One of the main permits you may need is the planning permission, which can be obtained from your local council. These steps, however, need to be finalised before we start working on your project. Please consult a solicitor, architect or the council to be certain your home renovation can continue without any delays.
Can you check the required water pressure before beginning my renovation?
Absolutely. We can assess and confirm water pressure levels to ensure your upgraded system performs reliably.
Can I upgrade my existing system with new components?
Yes, we can assess compatibility and connect your new, more powerful system to existing installations when appropriate.
Can you reposition the current piping instead of installing new pipes?
In many cases, we can reposition pipes for optimal layout without needing an entirely new system.
Can I provide materials for my plumbing renovation?
We’re happy to work with your materials, provided they meet local standards and project’s specifications.
For tailored advice, reliable service, and transparent costs, contact Lazard to discuss your renovation projects!
“Can’t recommend Lazard enough, they were friendly, courteous and professional throughout. The quotation I think was very fair, they even agreed to fit a new shower we needed within the original price. It’s not exactly fun when your boiler packs up, but they made the replacement a painless process, cannot be faulted in any way.”
