New Build
New build plumbing & heating in Chelmsford and Essex.
Plumbing and heating for self-builders, building contractors and developers in Chelmsford and across Essex. From system planning and first fix to installation and commissioning, discuss the plumbing and heating scope for your project.
The Work
Overview
Planning a single home or a residential development? Talk to us about the plumbing and heating before first fix, so the installation can be planned around the build.
Start your project
Discuss your new-build project.
Tell us where you are building, how many homes are planned and your current build stage. Include your expected first-fix date and whether you need plumbing, heating or both. If you have drawings or a specification, mention these in your enquiry so we can discuss the next step.
What's Included
Our service expertise.
01
System design
Heat loss calculations, cylinder sizing, distribution layout, designed for the building, not from a template. Planning low-temperature heating? See our air source heat pump installation advice.
02
First fix
Pipework, drainage, vents and chases laid out cleanly before plaster goes on. Tidy is faster downstream.
03
Second fix
Fixtures, boilers, cylinders, valves and controls. Tested as we go, not all at the end.
04
Underfloor heating
Wet UFH manifolds, weather-compensated controls and zoning that actually responds to the building.
05
Unvented cylinders
G3-qualified installation and commissioning, with full paperwork at handover. More on our unvented hot water cylinders page.
06
Gas Safe & compliant
Gas, unvented and water regs, all certified. Benchmark commissioning included.
Our Process
Precise from survey to handover.
01
Design review
We work with your drawings (or draw with you) to lock in system type, cylinder size, zoning and routing before first fix.
02
First fix
Soil, waste, hot, cold, gas and UFH pipework installed and pressure-tested before boarding.
03
Second fix
Suite, boiler, cylinder, controls, valves and brassware. Aesthetically tidy as well as functionally right.
04
Commissioning
Pressure tests, flow rates, benchmark, gas safety records and balance to design spec.
05
Handover
Certificates, schematics and a walkthrough. Everything the homeowner or buyer needs for warranty and resale.
Common Questions
Things people ask us.
Do you take on single new builds as well as developments?
+
Yes, from one-off self-builds and barn conversions through to multi-unit residential developments. Our process scales either way.
Can you handle system design from scratch?
+
Yes. We size the heating and hot water systems to the building, the insulation and how the home will actually be used, not a generic spec.
Are you Gas Safe and compliant with current regulations?
+
Yes. All gas work is Gas Safe registered. Plumbing, heating and unvented cylinders are installed to current Building Regulations and certified accordingly.
Do you carry out underfloor heating?
+
Yes, wet UFH for ground floors, retrofit overlay systems and combined UFH + rads with weather-compensated controls.
What documents do we get at handover?
+
Benchmark commissioning, unvented certificates, gas safety records, system schematics and a workmanship guarantee, everything you'll need at sale or warranty.
When should I contact a plumber for a new build?
+
Get in touch while you are planning the plumbing and heating, ideally before first fix. Include your build stage and expected dates so we can discuss the work required.
What information should I include in my enquiry?
+
Include the site location, number of homes, build stage, expected first-fix date and the plumbing and heating work you need. Let us know whether drawings and a specification are available.

I couldn't be happier with the service I received. Four new radiators installed at a great price, and the entire job completed in just one day. Everything was left clean and tidy and all the radiators were working perfectly before they left. Excellent value for money and clearly takes pride in their work.

We had Plumbers.ESX in for our new build house, amazing standard of work, installing the whole of the heating system and gas works including the underfloor, and all of the bathrooms. Really reliable guys.
