Principal Prime Plumbing EIP

A garage conversion can transform an underutilised space into a functional, high-value room, whether it’s a new kitchen, bathroom, or utility area, or even relocating a boiler to the loft. At Principle Prime Plumbing EIP Ltd, trading as Knightsbridge Elite Plumbing Services, we guide clients across Knightsbridge, Chelsea, Mayfair, and Belgravia through every stage of the conversion process.

1. Initial Consultation & Feasibility:
We assess your garage for size, structure, access, and utility connections. Key considerations include headroom, drainage, water supply, and ventilation. We discuss your goals — kitchen, bathroom, or utility conversion — and provide a clear feasibility report.

2. Planning & Approvals:
We prepare all planning and building control applications, ensuring compliance with UK building regulations, especially for heritage and luxury properties. This stage also includes coordination with structural engineers and other specialists.

3. Structural Preparation:
Work includes strengthening floors, installing insulation, reinforcing walls, and preparing the roof and framework for new rooms. Any structural changes needed for loft access or boiler relocation are handled by certified engineers.

4. Plumbing & Heating Installation:
Our Gas Safe-certified engineers handle all new pipework, boiler installation or relocation, radiators, and water connections for kitchens or bathrooms. We ensure systems meet modern efficiency and safety standards.

5. Electrical Work & Utilities:
We install safe, compliant electrical wiring, sockets, and lighting. Additional services include ventilation, heating controls, and smart home integration if required.

6. Interior Finishing:
Flooring, plastering, painting, and fixture installation are completed to high-end standards, whether it’s for a kitchen, bathroom, or luxury living space. Every detail is executed with precision, discretion, and attention to the property’s aesthetic.

7. Final Inspection & Handover:
All systems are tested for safety and performance. We provide clients with guidance on maintenance and ensure they are delighted with the result.

In short: From consultation and planning to plumbing, heating, electrical, and finishing, we manage every stage with expertise and care, delivering high-quality, luxury garage conversions that enhance comfort, functionality, and property value.

When we start a new project, we always begin by understanding your goals, budget, and timeline. We ask questions such as:
• What specific problem are you experiencing, or what upgrade are you planning?
• Do you have existing plans, photos, or specifications?
• What’s your preferred timeframe or any deadlines we should be aware of?
• Are there any access restrictions, parking, or building management requirements?
• Do you have preferred brands, fixtures, or materials?
• Would you like us to supply all materials or work with what’s already on site?
These details help us provide an accurate quote and complete the work safely, efficiently, and to your expectations.

What I love most about my job is the satisfaction of providing quality service to my customers and seeing the smile on their faces when they are pleased with the results. It is rewarding to know that my work has a positive impact on their lives and businesses. Moreover, I feel a sense of responsibility to ensure that my work generates a profit that can sustain and grow the business, which, in turn, provides jobs and contributes to the local economy.

Yes — while most of our plumbing and heating work is carried out on-site, we also provide online and remote support for clients who require quick professional assistance.

Our remote services include:
• Virtual consultations and video diagnostics — to identify issues before call-outs, saving time and cost.
• Online estimates and project planning — for bathroom renovations, boiler installations, or maintenance schedules.
• IT-integrated building support — remote guidance for connected heating systems, smart thermostats, and digital leak detection.

We serve clients across London and the Home Counties, offering flexible scheduling and rapid response both online and in person.

The health and safety of our customers and employees is our top priority, and we have taken a range of measures to keep them safe from Covid-19. First and foremost, we have implemented rigorous cleaning and sanitation protocols in our workplace and for any equipment that we bring to our clients' premises. We also provide our employees with personal protective equipment, such as masks and gloves, to ensure their safety and the safety of others.

In addition, we have adjusted our working practices to comply with social distancing guidelines. We have limited the number of workers on-site and have staggered our work schedules to minimise contact between individuals. We also conduct meetings and consultations with clients via phone or video conferencing when possible, to reduce in-person contact.

Moreover, we stay up-to-date with the latest guidelines and recommendations from health authorities and make any necessary adjustments to our practices accordingly. We are committed to ensuring that our customers feel safe and comfortable working with us during these challenging times.

Overall, we believe that these measures demonstrate our commitment to providing a safe and healthy environment for our customers and employees while continuing to deliver the high-quality services our customers expect from us.
