New water connections & mains supplies
New mains water connections for domestic, commercial and multi-plot developments — from demand calculations through to metering and temporary supplies.
What this service covers
A new water connection provides a supply from the regional water company's network. It typically involves a water demand calculation, an application, a quotation and design, and connection works including metering.
We coordinate the application and liaison with the regional water company, and manage main extensions or upgrades where the development requires them.

How it works
Six clear stages
Project review
You share the site address, plans, requirements, expected loads, unit numbers and target programme.
Site & capacity assessment
We review the information, identify likely network requirements and confirm any surveys still needed.
Applications & quotations
Applications are prepared and submitted to the relevant network operators, utility companies or contractors.
Option review
We review the available quotations, routes, programmes, responsibilities and commercial considerations with you.
Acceptance & coordination
Once you choose an option, we help coordinate approvals, payments, designs, permits and contractors.
Installation & connection
We track the project through installation, metering, commissioning and connection.
Utility timescales vary according to network capacity, permissions, design complexity, third-party works, road-opening requirements and provider availability. Early engagement is strongly recommended.
Good to know
Common challenges
Where the nearest main lacks capacity or is distant, a main extension may be required. We identify this early.
Fire supplies can change the design; we clarify requirements up front.
We help scope a sensible demand estimate for an accurate quotation.
Jargon, explained
Terminology
- Water demand calculation
- An estimate of the peak water demand your development will place on the network.
- Main extension

FAQs
Water questions
We prepare and submit the application to your regional water company, including the demand calculation, and coordinate the quotation, design and connection works.
Yes — temporary supplies can be arranged for construction, with a transition to permanent supply later.
We coordinate fire supply requirements as part of the design where they apply; specialist design input may be needed.
