Is a New Roof VAT-Free Under the Warm Homes Plan in 2026? (UK)
In most cases no. A full new roof or re-roof carried out for repair, replacement or appearance is normally standard-rated at 20% VAT in 2026. The 0% VAT relief people have heard about applies to specific energy-saving materials (ESMs) — insulation, solar panels, heat pumps and similar — not to the roof covering itself. The Warm Homes Plan is a separate government grant and upgrade programme for insulation and low-carbon heating; it is not a blanket VAT exemption on roofing. Where the two overlap is roof (loft or rafter) insulation, which can qualify for 0% VAT — but tiles, felt, battens and structural timbers on a like-for-like re-roof generally do not. Below we explain exactly what qualifies, what doesn’t, and how to avoid being over-charged — or mis-sold a “VAT-free roof” that isn’t.
Is a new roof VAT-free? The short answer
- A standard re-roof (new tiles, felt, battens, ridge) is not VAT-free — it is normally standard-rated at 20% VAT.
- 0% VAT applies to energy-saving materials (ESMs) — insulation, solar PV, heat pumps — when installed in a residential property, under the relief currently running to 31 March 2027.
- Roof insulation can qualify for 0% VAT — loft or rafter insulation counts as an ESM. The roof covering itself does not.
- The Warm Homes Plan is a grant / upgrade scheme, not a VAT exemption — it helps fund insulation and low-carbon heating, it does not make a whole new roof tax-free.
- Beware of “VAT-free roof” sales claims. If a roofer says your full re-roof is 0% VAT with no energy-saving element, ask them to show which HMRC relief applies — and get it in writing.
The confusion is understandable. The government has heavily promoted the Warm Homes Plan and the extended 0% VAT on energy-saving materials at the same time, and headlines often blur the two. But they are different levers: one is a spending / grant programme, the other is a tax relief on specific products. Neither one turns a like-for-like roof replacement into a zero-VAT job. The practical takeaway: the insulation and low-carbon elements of a roof project may be discounted or 0%-rated, while the structural and weatherproofing elements are usually full VAT. Get the two priced separately on your quote so nothing is over- or under-charged.
Roofing & VAT in 2026 — What Rate Applies to What
This table shows the typical VAT treatment for common roof-related works on an ordinary occupied home. It is general guidance based on HMRC’s energy-saving-materials relief (VAT Notice 708/6) — individual circumstances (new-builds, listed buildings, empty properties, mixed jobs) can change the rate, so always confirm with your installer.
The 0% ESM relief on solar, heat pumps and insulation currently runs to 31 March 2027 in Great Britain, after which it is scheduled to return to the reduced 5% rate unless extended. New-build zero-rating and the empty-home 5% reduced rate are separate reliefs with their own strict conditions — they are not part of the ESM scheme and do not depend on the Warm Homes Plan.
What the Warm Homes Plan Actually Covers
The Warm Homes Plan is the UK government’s flagship home-upgrade programme. Its purpose is to help households cut energy bills and carbon by funding insulation, draught-proofing and low-carbon heating — not to zero-rate roofing. It works through grants and scheme funding (delivered via routes such as the Warm Homes: Local Grant, the Boiler Upgrade Scheme and social-housing funds), typically targeted at eligible or lower-income households. It is best understood as help paying for energy upgrades, which is a different thing from a VAT rate on your roof.
What it typically funds
Loft & cavity/solid-wall insulation, draught-proofing, heat pumps, solar, smart heating controls — the energy-efficiency measures that lower bills. Roof insulation can sit inside this; a new roof covering generally does not.
What it does not do
It does not make a full re-roof VAT-free, and it is not an automatic entitlement — eligibility depends on the specific scheme, your income/benefits, property EPC and location. Always check the live scheme criteria before assuming you qualify.
So can the Warm Homes Plan help with a roof at all? Indirectly, sometimes. If your project includes a qualifying insulation upgrade — for example insulating at loft or rafter level while the roof is open — that insulation element may attract grant support and/or 0% VAT. The tiles, membrane, battens and structural repair that make the roof watertight are a separate, standard-rated building job. The clean way to handle this is to ask your roofer to itemise the insulation measure separately from the re-roof so the correct rate and any grant apply to the right line only.
When Part of Your Roof Job Can Be 0% VAT
Use this as a quick sense-check before you accept any “VAT-free” claim. The more of these that apply, the more likely a portion of your project genuinely qualifies for the 0% energy-saving-materials rate.
Likely 0% (ESM)
The work installs an energy-saving material — loft/rafter insulation, solar PV, a heat pump — in your existing home, by the installer as a single supply of goods and fitting, before the relief window closes (currently 31 Mar 2027).
Usually 20%
The work replaces or repairs the roof covering — new tiles/slates, felt, battens, ridge, flashings, structural timber — for weatherproofing or appearance, with no qualifying energy-saving material involved.
Separate reliefs (not ESM)
Brand-new build (0% zero-rated), a property empty 2+ years (5% reduced), or certain approved-alteration works — each has strict conditions and evidence requirements independent of the Warm Homes Plan.
Get it in writing
If any line is quoted at 0% or 5%, ask the installer to state which HMRC relief applies on the invoice. A legitimate installer will do this happily; a vague “it’s VAT-free” with no basis is a red flag.
