Heating and Plumbing in a New-Build House
New-build houses come with modern compact systems already fitted, so most of our work here is service, minor fault-finding, or making changes when a homeowner wants something different from the developer's standard specification..

Compact plant, tight cupboards
Combi boilers and mechanical ventilation units are often fitted into small utility cupboards with little slack for retrofitting extra kit later.
Warranty and building control records
New-build heating and hot water systems usually sit under a structural warranty and building control sign-off, both worth checking before any alteration.
Underfloor heating on the ground floor
Many new-builds mix underfloor heating downstairs with radiators upstairs, which means two flow temperatures managed from one manifold.

Tell us what the developer fitted and what you'd like changed, and we'll confirm what's realistic within the existing layout.
Questions we get asked
Can I add a second bathroom later?
Usually possible, but flow rate and boiler output need rechecking rather than just adding a branch pipe.
Why does my underfloor heating feel cooler than radiators?
It runs at a lower flow temperature by design. It's not a fault, though poor manifold balancing can make it feel uneven.
Does servicing affect my new-build warranty?
Missing services can affect manufacturer warranty on the boiler specifically, separate from the NHBC structural warranty.
