New builds, annexes, garden buildings and plots being split all need a brand-new water supply laid from the boundary — and often a new connection to the main itself.
WaterTrust Approved — every contractor is identity-checked with accreditation and insurance verified before they can quote.
What the work involves
- Trenching or moling a new MDPE supply at the correct depth (750mm)
- Ducting where the route passes under structures or drives
- Installation of the internal stop tap and any boundary boxes
- Coordination with the water company's connection requirements
When you need it
- A new build or conversion needing its first supply
- Splitting one supply into separately-metered feeds
- A garden office, stable block or outbuilding needing water
- Replacing a shared supply with your own dedicated pipe
What a new supply pipe costs in Arundel
A new domestic supply — blue MDPE from the boundary to the property, ducted and insulated to standard — typically lands £800–£2,500 with length and surfaces crossed the main drivers. New connections also carry the water company's own connection and meter charges, quoted separately by them.
Getting it right first time
- Correct depth (750mm–1.35m) and ducting where required
- Barrier pipe through contaminated ground — old industrial land, near fuel tanks — where the rules require a pipe pollution cannot pass through
- Sized to the property — often improving pressure over an old shared supply
- Company notification and inspection before backfill
- Extending over the existing supply? Reroute before the slab goes down — the supply-pipe version of the drain build-over problem
