Free quote in one working day. [Get a Quote →](/quote) The 0% rate isn't a discount — it's the absence of VAT on the supply and installation of energy-saving materials. On a typical installation that's £1,200–£1,800 saved versus the standard 20% rate. After March 2027, the rate is uncertain. ## What the rate covers The zero rate applies to the supply and installation of energy-saving materials (ESMs) on residential premises. For solar specifically, this covers: - Solar PV panels - Battery storage systems - Inverters (as part of a solar installation) - Associated equipment and installation labour Both the products and the installation labour are zero-rated — so the full installed cost attracts. Domestic only The 0% rate applies to domestic properties. Commercial solar installations remain at 20% standard rate VAT, which VAT-registered businesses reclaim as input VAT. ## How much the 0% rate saves you System price At (now) At 5% (old rate) At 20% (standard) Saving vs 5% Saving vs 20% £5,999 £5,999 £6,299 £7,199 £300 £1,200 £6,999 £6,999 £7,349 £8,399 £350 £1,400 £9,000 £9,000 £9,450 £10,800 £450 £1,800 The saving vs the old 5% rate is £300–£450 — meaningful but not dramatic. The saving vs standard 20% is £1,200–£1,800 — more significant. ## What happens after March 2027? The current legislation (Finance Act 2022) sets the 0% rate until 31 March 2027. After that date, the rate reverts — and that reversion depends on a future government decision: - Option A: the government extends the 0% rate beyond March 2027 — a strong possibility given energy security and net-zero policy commitments. - Option B: the rate reverts to the previous 5% reduced rate — a modest increase. - Option C: the rate reverts to 20% standard rate — unlikely for domestic solar given policy direction, but technically possible. The most likely outcome is an extension or a reversion to 5%. A full reversion to 20% would be a significant policy reversal and is not currently signalled by any mainstream party. But the 0% rate is a current legislative fact; the rate after March 2027 is uncertain. A real, not manufactured, deadline The March 2027 deadline is a genuine reason to act sooner rather than later. The 0% rate currently saves you hundreds of pounds, and locking that in by installing before the deadline is straightforward financial logic. ### Lock in the 0% rate Get a fixed-price quote from a renewable energy engineer — no sales pressure. [Get a quote](/quote) [View fixed-price packages](/services/solar) ## The wider picture: why now is a good time - Panel and battery prices have stabilised after years of decline — further significant falls are unlikely near-term - Smart tariffs and the Levelise Hub are more capable than ever — the same hardware installed today performs better financially than three years ago - Electricity prices remain elevated — the payback on solar at current rates is significantly better than at pre-2021 prices - Warm Homes Plan funding is in its early delivery phase — grant funding is more accessible now than it may be once demand increases ## Does the VAT saving apply to the Levelise Hub and battery storage? Yes — the Levelise Hub is part of the solar installation package and attracts the same 0% rate. All components Alliant supplies as part of a domestic solar and battery installation are zero-rated under the current legislation. Battery storage installed alongside solar attracts. Battery storage installed as a standalone measure (not alongside solar) may attract 5% rather than 0% depending on the specific circumstances. We can advise when you enquire. ## Frequently asked questions ### Is the rate guaranteed until March 2027? The 0% rate is in primary legislation (Finance Act 2022) until 31 March 2027. It would require an Act of Parliament to change it before that date — which is not being proposed by any party. ### Do I need to do anything special to get the rate? No. The 0% rate applies automatically to domestic solar installations by any VAT-registered installer. Our package prices (£5,999, £6,999, £9,000) are already the zero-rated prices — there's no VAT to add. ### What about commercial solar — does 0% apply? No. The 0% rate applies to domestic properties only. Commercial solar installations attract 20% standard rate VAT, which VAT-registered businesses reclaim as input VAT in the normal way.
