From targeted upgrades to full property refurbishments, we plan systems that integrate cleanly with the build and perform long after completion.
We support residential projects at every stage, from early planning through to installation and handover.
Each service below links to a dedicated page with full detail.

BWe install high-efficiency boiler systems designed to suit the property, layout, and level of demand.
Used on refurbishments, upgrades, and new builds where performance, reliability, and proper system planning matter.

We replace boiler systems that are no longer suitable for the property, layout, or level of demand.
Typically used during refurbishments, extensions, and planned upgrades where system performance and compatibility need to be reassessed properly, not swapped like for like.

We plan and install the plumbing systems that support residential bathrooms, from individual en-suites to multi-bathroom properties.
Used on refurbishments and new builds where pressure, flow rates, pipe routing, and coordination with other trades need to be resolved early.

We design and install water-based underfloor heating systems as part of wider residential plumbing and heating schemes.
Typically specified on refurbishments, extensions, and new builds where floor build-ups, zoning, heat output, and coordination with structure and finishes need to be planned properly from the outset.

We design and install complete plumbing systems for residential projects where layout, demand, and future use need to be considered as a whole.
Used on new builds and full refurbishments where pipe routes, plant locations, pressure requirements, and coordination with the wider build need to be resolved before work begins..

We design and install air source heat pump systems where the property, insulation levels, and heat demand support their use properly.
Typically considered on new builds and major refurbishments where system design, heat loss, emitter selection, and wider integration need to be assessed before specification.

We design and install water booster systems for properties where incoming mains pressure or flow is not sufficient for the level of demand.
Typically specified on larger homes, multi-bathroom refurbishments, and high-demand projects where pressure, flow rates, and simultaneous usage need to be resolved as part of the wider plumbing design.

We design and install unvented hot water cylinder systems for residential properties where hot water demand, flow rates, and simultaneous usage need to be supported properly.
Typically specified on refurbishments, extensions, and new builds with multiple bathrooms, where sizing, pressure management, and G3 compliance need to be addressed as part of the overall system design.

We design and install radiator systems that are correctly sized and integrated with the wider heating system to deliver consistent heat output across the property.
Typically used during refurbishments, extensions, and heating upgrades where existing radiators no longer suit the layout, heat demand, or system design.
Every plumbing and heating system we install is designed around long-term reliability, serviceability, and performance, not just what works on installation day.
Material choice, system layout, and installation methods are considered in the context of the wider project, the property’s usage, and how the system will be maintained over time.
In many cases, that leads us to specify traditional copper pipework for its durability, repairability, and proven performance, particularly on larger or more complex installations.
That does not mean one solution fits every project. It means decisions are made deliberately, based on suitability, access, longevity, and how the system will actually be used.
The result is a plumbing and heating system that remains dependable long after the project is complete.

Clients choose Sable Projects because we approach plumbing and heating with the same level of planning, coordination, and accountability expected across the wider build.
Our work is structured around clear scopes, realistic timelines, and systems that are designed properly before installation begins. We coordinate closely with other trades, follow drawings and specifications accurately, and communicate early if something needs to be resolved.
On site, we work cleanly and methodically, respecting the property, the programme, and the people involved. Systems are installed to perform reliably, remain serviceable, and integrate cleanly with the rest of the project without shortcuts or late compromises.
For clients managing complex residential work, that reliability matters.
