Why Choose Us for New Build Plumbing and Heating?
Complete Plumbing and Heating for New Build Homes
System Design and Planning
Every project starts with detailed planning. We design full plumbing and heating layouts for single homes and multi unit developments, including load calculations, cylinder positioning, pipework routes and boiler or heat pump requirements. As Gas Safe and OFTEC registered engineers, our designs follow current regulations and are fully aligned with modern heating control systems.
First Fix Plumbing and Heating
We install all internal pipework for hot and cold water, heating circuits, waste runs and system layouts. Pipe routes are planned for easy access, clean lines and long-term reliability. All work meets building regulations and manufacturer standards.
Boilers, Cylinders and Heating Systems
We install efficient boilers, unvented cylinders, heating manifolds and modern control systems tailored to the home. Whether the project uses gas, oil or renewable heating, all installations are handled by qualified Gas Safe and OFTEC registered engineers.
Site Preparation and Coordination
Before first fix begins, we work with builders and site managers to coordinate timelines, access and installation requirements. This stage ensures correct placement of services, ventilation, plant areas and future access points, helping the build run smoothly from the start.
Second Fix Installation
When the property is ready, we fit sanitaryware, radiators, taps, showers, valves, heating controls and all finishing components. Our team work cleanly and precisely to leave each property with a high-quality, professionally finished result.
Testing, Commissioning and Final Sign-off
Every system is carefully tested, balanced and commissioned to meet building regulations and provide reliable performance from day one. We complete all required documentation and ensure everything is fully ready for handover.

Can’t recommend Plumbers.ESX more… fabulous new bathroom after a complete rip out. They were flexible and supportive when we encountered a few hiccups. So pleased with the result and finish, they will be busy as I have passed on their number to everyone I know!

Connor replaced our old boiler and we couldn’t be happier with the overall service and experience that they provided! Made the process painless and the new boiler works perfectly. Would highly recommend and would definitely use again for other plumbing services.

Frequently Asked Questions
What does new build plumbing and heating include?
It covers full system design, pipework installation, hot and cold water distribution, heating circuits, waste runs, boilers or cylinders, controls, testing and commissioning, all completed to current UK building regulations.
When does plumbing and heating work start on a new build?
It begins during the first fix stage once the property structure is in place. This is when all internal pipework, heating circuits and waste runs are installed before walls and floors are finished.
What is the difference between first fix and second fix in a new build?
First fix is all the hidden pipework. Second fix involves fitting radiators, taps, showers, sanitaryware, valves and modern heating controls once the rooms are ready for finishing.
Do you design the plumbing and heating system for the build?
Yes. System design includes boiler or heat pump requirements, cylinder sizing, load calculations, pipework routing and control layout to ensure compliance, efficiency and long-term reliability.
Are new build plumbing systems more efficient than older ones?
Yes. New systems must meet current UK standards, with better insulation, modern boilers or cylinders, efficient pumps and advanced heating controls that help reduce energy usage.
Who signs off the plumbing and heating work on a new build?
A qualified engineer completes the testing, balancing and commissioning, ensuring everything meets building regulations. Documentation is provided for the builder or homeowner at handover.
Do new builds need an unvented cylinder or a combi boiler?
It depends on the property size, number of bathrooms, water demand and design preferences. Unvented cylinders suit high-demand homes, while combis work well for smaller properties. A design assessment determines the right option.
What heating controls are used in modern new builds?
Most new builds use programmable thermostats, smart controls, zoning, weather compensation or load compensation to improve efficiency and meet regulatory requirements.
Can underfloor heating be included in a new build?
Yes. Underfloor heating is commonly installed during first fix and integrates with boilers, cylinders or heat pumps. It provides even heat distribution and works well in modern insulated homes.
Are you qualified to install gas, oil or renewable heating in new builds?
Yes. All installations are completed by qualified, Gas Safe and OFTEC registered engineers who work to current regulations and modern heating control standards.
