On a care home development, the difference between zero-rating and 20% is often the difference between a scheme working and a scheme not working. The operator makes exempt welfare supplies and cannot recover the VAT, so it lands as an absolute cost. Whether the relief is available at all can turn on a single piece of paper — and on whether that piece of paper was needed in the first place.

The question in the title is the one that causes most of the trouble. A certificate is not a formality to be issued as a matter of course, nor is it something every qualifying building requires. Issuing one where it is not needed, failing to issue one where it is, or issuing one that turns out to be wrong all carry consequences — and they fall on different parties.

Two Reliefs, One Certificate Requirement

Zero-rating for the construction of new buildings sits in Schedule 8, Group 5 of VATA 1994. Two categories matter here:

  • Buildings designed as dwellings — zero-rating applies automatically where the statutory conditions are met. No certificate is required.
  • Buildings intended for use solely for a relevant residential purpose (RRP) — zero-rating applies only if the customer issues the contractor with a certificate confirming the intended use. No certificate, no zero-rating.

So the real question is not “do we need a certificate?” in the abstract. It is: which relief are we relying on? Establish that first, and the certificate question answers itself.

Dwelling or Relevant Residential Purpose?

For a conventional care home — bedrooms with shared dining, lounge and care facilities, with personal care provided throughout — the answer is RRP. The units are not self-contained dwellings, and a certificate is required.

The difficulty arises with extra-care housing, assisted living and retirement villages, where accommodation is often built as genuinely self-contained flats with their own kitchen and bathroom, sold or let on long leases, with care available but not integral to occupation. Those may well be dwellings, in which case zero-rating applies without a certificate.

To qualify as a dwelling, the statutory conditions require that the dwelling consists of self-contained living accommodation, that there is no internal access to any other dwelling, that planning consent has been granted and the construction accords with it, and — the condition most often fatal — that separate use or disposal of the dwelling is not prohibited by planning permission or any similar provision.

That last condition defeats a great many extra-care schemes. Planning consents on this type of development frequently tie occupation to people over a certain age, or to those assessed as needing care, or restrict disposal other than in conjunction with the wider scheme. Where the consent prohibits separate use or disposal, dwelling treatment is lost, and the analysis falls back to whether the building qualifies as RRP instead.

Read the planning consent and the section 106 agreement before deciding. This is not a question that can be answered from the architect’s drawings.

What Counts as a Relevant Residential Purpose

The RRP definition covers, among other things, a home or institution providing residential accommodation with personal care for people in need of it by reason of old age, disablement, or past or present dependence on alcohol or drugs, or past or present mental disorder. It also covers children’s homes, hospices, student and armed forces accommodation, and any institution that is the sole or main residence of at least 90% of its residents.

The definition expressly excludes use as a hospital, prison or similar institution, or as a hotel, inn or similar establishment. Care homes providing nursing generally remain within RRP rather than being excluded as hospitals, but the boundary is a genuine risk area for facilities with a strong clinical character, and it deserves thought rather than assumption on specialist schemes.

The Certificate Itself

Several points matter in practice:

  • The certificate is issued by the customer — the person to whom the supply is made — not by the contractor. The contractor relies on it; it does not produce it.
  • It must be given to the contractor before the supply is zero-rated. A certificate produced after the event, once HMRC has raised a query, is not the same thing.
  • It certifies intended use. The test is applied at the time of supply, on the basis of what the building is genuinely intended to be used for.
  • The form of certificate is set out in VAT Notice 708. Use it rather than improvising wording.

Sub-Contractors Cannot Zero-Rate

This is the single most commonly missed point on RRP schemes, and it produces irrecoverable VAT with dispiriting regularity.

Zero-rating under this relief applies to services supplied to the person who intends to use the building for the qualifying purpose. A main contractor supplying the developer or operator can zero-rate against a valid certificate. A sub-contractor supplies the main contractor, not the end user — so the sub-contractor’s supply does not qualify, and must be standard-rated at 20%.

Where the main contractor is fully taxable this is merely a cash-flow point, since it recovers that VAT and zero-rates its own onward supply. But it must be priced and funded correctly, and sub-contractors who zero-rate in error — often because they have been shown the certificate and assume it applies to them — will be assessed. The certificate belongs to one supply in the chain only.

Note also that the construction industry domestic reverse charge does not apply to zero-rated supplies, so the two regimes interact along the same contractual chain and need to be mapped together.

The “Solely” Requirement

The building must be intended for use solely for the relevant residential purpose. Strictly applied, any non-qualifying use defeats the relief entirely.

In practice HMRC accepts a de minimis allowance, treating the condition as met where non-qualifying use is no more than 5%. That accommodates incidental use — a small office, a visitor facility — but it will not cover a genuinely mixed development. Where a scheme combines a care home with, say, a commercial gym, a day centre open to the public, or retail space, the relief needs to be considered building by building and apportioned appropriately.

Conversions

New build is not the only route. Where an existing non-residential building is converted into a care home, different provisions apply:

  • The reduced rate of 5% is available for a special residential conversion — broadly, converting premises into a building intended for use for a relevant residential purpose.
  • Zero-rating on conversion is narrower and is generally available on the first grant of a major interest by the person converting, rather than on the construction services themselves.

The distinction between conversion, alteration, extension and enlargement also matters, and has generated a good deal of litigation. Works that appear to be an extension of an existing building may in substance be the construction of a new one — and vice versa. On a marginal scheme, this is worth resolving before contracts are let.

Change of Use Within Ten Years

Zero-rating obtained on the strength of a certificate is not permanent. Where, within ten years of completion, the building ceases to be used for the qualifying purpose — through a change of use, or a disposal — a self-supply charge arises, clawing back a proportion of the VAT that was relieved.

This is a live risk on care schemes, which change hands, get repurposed, or fall out of RRP use when a service model changes. It needs to be flagged in the sale documentation and diarised, because the liability sits with the person whose use changes and can surface long after the original advisers have gone.

The Penalty for an Incorrect Certificate

Because the contractor zero-rates on the strength of the customer’s certificate, the legislation places the risk on the person who issued it. Where a certificate is issued incorrectly, the person issuing it can be liable to a penalty equal to the VAT that was undercharged.

That is a meaningful exposure on an eight-figure development, and it is the reason a certificate should never be signed as a routine piece of project administration. It is a statement about intended use, made by the person best placed to know, and relied on by a third party who will otherwise carry the assessment.

A Practical Checklist

  • Decide first whether you are relying on dwelling or RRP treatment — only the latter needs a certificate
  • Read the planning consent for any prohibition on separate use or disposal before assuming dwelling status
  • Confirm the intended use falls within the RRP definition, and is not caught by the hospital or hotel exclusions
  • Issue the certificate before the supply, in the form set out in Notice 708, and keep the supporting reasoning
  • Map the contractual chain: only the supply to the certificate holder can be zero-rated — sub-contractors charge 20%
  • Check non-qualifying use against the 5% allowance, and apportion genuinely mixed schemes
  • On conversions, test whether 5% reduced rating applies rather than zero-rating
  • Diarise the ten-year change of use period and address it in any sale or restructuring

Care home developments involve large sums, an operator who usually cannot recover VAT, and a relief that depends on documents produced at the right moment by the right party. The analysis is best done before contracts are signed and certificates issued: once a sub-contractor has zero-rated incorrectly, or a certificate has been given for a building that does not qualify, the options narrow considerably. Our wider work in this area is set out under welfare and social services.
