At Heritage Living Group, we design and build high-performance SIPs buildings that are made to last. Whether your project is a garden studio, luxury lodge, sports facility, annexe or residential lodge, our guarantees reflect the quality of materials, engineering and craftsmanship that go into every Heritage building.
Our approach is simple: build properly, specify premium systems, and stand behind them.
All Heritage buildings are constructed using Structural Insulated Panels (SIPs) to form the walls, floors and roof structure.
Every building benefits from a 25-year structural guarantee covering the structural integrity of the SIPs system when installed and maintained in accordance with our specifications.
We specify high-performance roof systems designed for long-term weather protection and durability.
Up to 50-year manufacturer-backed guarantee on approved roof membranes and systems
Installed strictly in line with manufacturer guidance
Warranty passed directly to the client in full
Where ground screws are specified, buildings are supported on engineered ground screw foundation systems designed for long-term structural stability.
25-year manufacturer-backed guarantee on the ground screw system
Suitable for a wide range of ground conditions
Minimal ground disturbance and fully engineered load performance
This guarantee applies to the ground screw system itself and is passed on to the client in full, subject to manufacturer terms and correct installation.
We use a wide range of premium, manufacturer-approved external finishes and systems. Warranty periods vary by product type and manufacturer.
All external cladding is covered by manufacturer warranties, which are passed directly to the client. These may include:
Natural timbers (e.g. Larch, Cedar, Thermowood)
Modified timbers (e.g. Accoya®, Abodo®)
Composite and engineered boards (e.g. Millboard®)
Metal and standing seam systems
Specific warranty lengths are confirmed at specification stage and included in your project documentation.
Approved UK manufacturers supply all aluminium and uPVC windows and doors.
Manufacturer warranties apply to frames, finishes and glazed units
Sliding, bi-fold and entrance door systems included
Warranties are passed on in full to the client
Many internal components are supplied with their own manufacturer’s warranties, which are passed on in full where applicable. These may include:
Heating systems and controls
Electrical components and lighting
Kitchens, appliances and worktops
Bathroom fittings and sanitaryware
Flooring systems
Warranty periods vary by product and manufacturer.
Every Heritage building is supplied with a detailed aftercare and maintenance guide.
Correct maintenance:
Preserves appearance and performance
Protects manufacturer warranties
Maximises the long-term lifespan of your building
Where a defect arises:
The client must notify Heritage Living Group in writing as soon as the defect becomes apparent
The defect must be proven to result from faulty design, materials or workmanship
The aftercare guide must have been followed
Manufacturer warranties apply to third-party supplied products and are passed on in full
Where applicable, we will repair or replace defective items at our discretion, or refund the value of the faulty component where appropriate.
Your Heritage building is designed as a long-term asset, not a short-term structure. Our guarantees reflect the confidence we have in our design process, materials and construction standards — across every division of the Heritage Living Group.
