THE PROPERTY FILTER TAKE

  • The cost of renovating the UK's vacant property stock has reached £34bn, up 19% year-on-year, according to BuildLoan analysis.

  • Rising renovation costs compound the tax burden facing owners of empty homes. Council tax premiums, lost VAT relief windows, and deferred capital gains all increase the cost of delay.

  • You may wish to review whether your empty property qualifies for reduced-rate VAT on renovation works, and speak to your accountant about the council tax premium applicable in your local authority area.

The cost of renovating the UK's vacant property stock has risen to £34bn, up 19% year-on-year, according to new analysis by BuildLoan. That is a significant number. But for property owners sitting on empty homes, there is a more immediate concern: the tax cost of doing nothing.

The Tax Cost of Holding an Empty Home

Councils in England can now charge an Empty Homes premium on council tax (a surcharge applied to properties vacant for a qualifying period) of up to 300% for long-term empty properties. The threshold and rate vary by local authority, but the direction of travel is clear: holding costs are rising.

For example, on a property with an annual council tax liability of £2,000 (illustrative), a 100% premium doubles that to £4,000. A 300% premium takes it to £8,000 per year. Speak to your accountant about your specific liability and the applicable local premium rate.

VAT (value added tax) on renovation work may also be relevant. Qualifying residential conversions can attract a reduced 5% VAT rate rather than the standard 20%, according to HMRC guidance. That difference matters on a large renovation budget.

What the £34bn Figure Means for Your Position

BuildLoan's analysis suggests renovation costs across the vacant stock have risen sharply, driven in part by labour shortages and material price inflation, according to industry commentary. A 19% year-on-year increase outpaces general inflation by a significant margin.

The number that matters: if your renovation budget has risen by 19% and your holding costs have also increased, the case for delay weakens materially.

SDLT (Stamp Duty Land Tax) implications depend on your ownership structure and whether the property qualifies for any relief. Capital allowances (which reduce your taxable profits on qualifying renovation expenditure) may also be available in certain circumstances, according to HMRC guidance. These are areas where professional advice is essential.

You may wish to review the interaction between renovation timing, VAT relief eligibility, and your overall tax position before committing to a programme of works. Speak to your accountant.
