Utility Connections (Water, Gas, Electric)

Safe, certified connections to mains water, gas and power.

New builds and major renovations need safe, compliant connections to mains water, gas and electricity. Each utility has its own regulations and approved installers — water work must be WRAS-compliant, gas work must be carried out by Gas Safe registered engineers, and electrical work must follow BS 7671 (IET Wiring Regulations). Damage during excavation is one of the most common causes of utility incidents.

Common Damage

1. Water Supply Damage

  • Pipe leaks or bursts from freezing, corrosion or pressure
  • Low pressure from blockages or leaks
  • Contamination from backflow or damaged mains

2. Gas Supply Damage

  • Gas leaks from joint failures or corroded pipes
  • Damage from excavation works without surveys
  • Smell of gas, hissing sounds or dead vegetation near pipes

3. Electrical Supply Damage

  • Cable wear, insulation failure or rodent damage
  • Overloaded circuits and short circuits
  • Water damage to wiring or distribution boards

4. Excavation Strikes

  • Hitting unmapped underground services
  • Causing leaks, outages or serious injury
  • Always requires utility mapping before digging

Repairs

minor Repairs

  • Tighten connections and replace washers
  • Repair small water leaks with clamps or sleeves
  • Replace damaged sockets, switches and faceplates

moderate Repairs

  • Replace short sections of corroded pipework
  • Install backflow prevention devices
  • Upgrade fuse boards and earthing/bonding

major Repairs

  • Full replacement of supply pipework (PVC/PEX)
  • Gas leak isolation, replacement and pressure testing
  • Re-wire affected circuits and re-certify (EICR)

New Installation

When Replacement Is Needed

  • New build, extension or change of use
  • Existing supply is undersized or non-compliant
  • Upgrading to smart meters or higher capacity
  • Connecting outbuildings or annexes

Installation Steps

  1. Survey & Apply for Supply

    • Locate existing services with utility mapping
    • Apply to water, gas and DNO providers for new connections
    • Agree connection points and meter positions
  2. Water Connection

    • Connect to public mains via licensed provider
    • Install stop valve, water meter and internal pipework
    • Pressure test and ensure WRAS compliance
  3. Gas Connection

    • Gas Safe registered engineer connects to mains
    • Install meter, regulator and internal pipework
    • Tightness test and certify before commissioning
  4. Electrical Connection

    • DNO installs cut-out and meter
    • Install consumer unit and circuits to BS 7671
    • Test, inspect and issue Electrical Installation Certificate
