Make Your Project Energy Efficient — and VAT Efficient
VAT on Energy Saving Materials
The installation of energy saving materials (ESMs) such as insulation, solar panels, heat pumps, and other sustainable technologies can now qualify for zero-rated VAT in many cases. This relief represents a significant opportunity for homeowners, developers, and contractors — but the rules are intricate, and getting them wrong can lead to expensive corrections later.
At Landmark PT, we help clients secure the maximum VAT relief available by analysing each project in detail — ensuring the works, contracts, and invoices are structured correctly from the outset.
Why It Matters
The government’s expansion of VAT relief for energy saving materials has made energy efficiency one of the most active areas in the construction sector.
However, the qualifying conditions depend on several key factors:
The type of materials and systems being installed.
Whether the works are supply-only or supply-and-installation.
The type and use of the property — private, charitable, or mixed-use.
The way contracts and invoices are structured.
These details determine whether the correct VAT rate is 0%, 5%, or 20%, and they are often misunderstood on site. Our role is to make sure the VAT treatment reflects the true nature of the works — correctly, confidently, and compliantly.
