Underfloor heating pipework laid in a new build property in Essex by Plumbers ESX

New Build

New build plumbing & heating in Essex.

Smart system design, tidy workmanship and full compliance, delivered across Essex. From single self-builds to multi-unit developments, we keep projects running smoothly from first fix to final commissioning.

The Work

Overview

New build plumbing and heating is unforgiving, the wrong layout at first fix is a problem for the next forty years. We get it right the first time.

What's Included

Our service expertise.

01

System design

Heat loss calculations, cylinder sizing, distribution layout, designed for the building, not from a template.

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 registered installation and commissioning, with full paperwork at handover.

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.

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.
