Most building work is standard-rated, but construction VAT has important exceptions. The right rate depends on the exact supply, property/building use, timing and conditions—not simply whether the work is “construction”, residential or for a homeowner.
Use an evidence-first sequence
- Define exactly what is being supplied: labour, materials, design, repair, conversion or construction work.
- Identify the building/property and its relevant use at the time of the supply.
- Check whether a specific zero/reduced-rate rule and every condition can be evidenced.
- Keep certificates, plans, customer statements and supporting correspondence where current HMRC guidance requires them.
- Record the decision basis with the quote/invoice; revisit it if scope or facts change.
HMRC's Notice 708 describes circumstances in which qualifying new buildings, conversions, alterations for disabled people or other specified work may receive different treatment. A domestic address alone is not enough evidence. If the supply is mixed or the facts are unclear, seek VAT advice before issuing the invoice.
Common errors
- Applying a reduced/zero rate because the customer expects it.
- Reusing the rate from an earlier job with different facts.
- Treating a certificate or a verbal assurance as sufficient without checking its relevance.
- Mixing the domestic reverse-charge decision with the VAT rate decision.
