Major renovations raise a lot of questions — costs, timelines, contractors, temporary facilities. One that often gets overlooked until the dust settles is what happens to your council tax. There are really two separate questions, and the answers are very different: what you pay while the property is empty and being worked on, and whether your band changes permanently afterwards.
If you're a homeowner planning a significant refurb, or a landlord turning a rental around between tenancies, the first of those can cost you more than you'd expect — so it's worth understanding before the work starts, not after.
What you pay while the property is empty during works
The common assumption is that an empty property mid-renovation gets a council tax discount. For most people, in most areas, that is no longer true.
Since councils were given control over empty-property discounts, the great majority have removed them. An empty, unfurnished home today usually attracts the full council tax charge — often from the day it falls empty, or after only a very short grace period. Do not budget on the basis of a discount you may not get.
The "major repairs" exception — and why a normal renovation won't qualify. There is a statutory exception for properties that genuinely need major repair work or structural alterations to make them habitable. Where it applies, it typically runs for up to 12 months. But the bar is high and specific: it is meant for uninhabitable or structurally unsound properties, not ordinary improvement work. Replacing windows or doors, refitting a kitchen or bathroom, plasterboarding, rewiring, replumbing and decorating do not count. A standard kitchen renovation, however extensive, will not usually qualify.
Even where relief applies, it's usually only from the premium. Being excepted from an empty-homes premium does not mean you pay nothing — in most cases the full standard council tax charge is still due. (In rare cases a property that is genuinely derelict and incapable of occupation can be removed from the council tax list altogether by the Valuation Office Agency, but that is a high bar — confirm with your council and the VOA.)
The real sting: the empty-homes premium. If a property stays empty and unfurnished beyond a set period, councils can add an empty-homes premium on top of the full charge. This is where a slow or stalled renovation catches people out:
- The power has existed since 2013, and the maximum charges were extended in later legislation.
- From 1 April 2025, many councils in England apply the premium after the property has been empty for just one year — reduced from the previous two years.
- The premium escalates with time: commonly up to 100% extra (double your normal bill) once the trigger period passes, rising to around 200% after five years and 300% after ten years empty, where a council applies it.
So a renovation that overruns — or a rental left empty too long between tenancies — can quietly move you from paying the full charge to paying double. The exact trigger period and rates vary by council, so confirm your own authority's policy.
What to do. Contact your council before works begin, not after. Ask specifically about: the charge for an empty, unfurnished property; whether any major-repairs exception could apply to your project; and the date from which an empty-homes premium would kick in for your area. Get the answer in writing. Landlords especially: a void period plus a refurb is exactly the window in which a premium starts to bite.
(Rules differ in Scotland and Wales, which run their own empty-property and second-homes premium regimes — check locally if your property is there.)
Does renovation affect your council tax band permanently?
This is where many people misunderstand how banding works.
Council tax bands in England and Scotland are based on what a property would have sold for in April 1991 (Wales uses April 2003 values) — not current market value, and not the value after your renovation. In most cases, even significant improvements will not automatically trigger a rebanding.
The Valuation Office Agency (VOA) can reassess a property's band when it is sold, when a material change is made (such as an extension that adds floor area), or when someone makes a formal challenge. Importantly, an improvement like an extension does not change your band straight away — it is noted but generally only takes effect when the property is next sold. So renovating and staying put usually won't move your band, and simply replacing a kitchen — even a high-specification one — is very unlikely to trigger a rebanding.
There is, however, an important flip side. If your property was banded incorrectly back in 1991 — for example, valued cheaply because it was in poor condition at the time — it may have been in the wrong band all along. A property assessed cheaply in 1991 and improved since may now be correctly banded, or it may still be sitting in too low (or too high) a band.
The only way to know is to check. TaxBandCheck is a free tool that lets you check your current council tax band and compare it against similar properties nearby. For landlords managing several properties, the portfolio checker lets you run up to 50 postcodes at once to spot anomalies across a portfolio.
What about a temporary kitchen during the renovation?
A full kitchen renovation — in a family home or a rental — typically takes two to six weeks, and longer for bespoke or high-specification installations. During that time, a functional cooking and welfare space matters, and it also helps keep the project moving (and the property from sitting empty longer than it needs to).
Temporary kitchen units are available to hire across the UK, from compact domestic pods that sit on a driveway or in a garden, through to full commercial-grade catering facilities for larger projects. They're particularly common on:
- HMO refurbishments where tenants need to remain in occupation during phased works
- Large residential renovations where the family can't easily relocate
- Commercial kitchen remodels where trading continuity matters

A checklist for landlords and homeowners before major works
- Contact your council to confirm the empty-property charge, any major-repairs exception, and the date an empty-homes premium would start for your area.
- Check your current council tax band to see whether you're already overpaying — before you spend money on improvements.
- Notify your insurer before works begin — most policies have specific requirements for unoccupied properties.
- Plan temporary facilities if the kitchen will be out of use for more than a week or two, and use the hire checklist on delivery day.
- Keep records — dated photos and receipts support your position if a band challenge or an insurance claim arises later.
FAQ
Do I get a council tax discount while renovating? Usually not. Most councils have removed discounts for empty, unfurnished properties, so the full charge typically applies. A statutory exception exists for properties needing major repairs or structural work to make them habitable, but it does not cover routine work like a kitchen or bathroom refit, rewiring or decorating. Always confirm your council's current policy.
Can a long renovation increase my council tax? Yes. If the property stays empty and unfurnished past your council's trigger period — from 1 April 2025 often just one year in England — an empty-homes premium can be added on top of the full charge, up to double the bill, rising further the longer it stays empty.
Does a new kitchen raise my council tax band? No. Replacing a kitchen won't trigger a rebanding. Bands are based on 1991 values (2003 in Wales), and improvements like extensions generally only affect the band when the property is next sold.
I'm a landlord with a void between tenancies — am I at risk of a premium? Potentially. Empty, unfurnished void periods count towards the empty-homes trigger, and a refurbishment void is exactly when a premium can start. Check your council's trigger period and any exceptions, and keep void periods as short as you can.
Make the project stack up
Major renovations are one of the biggest financial decisions a property owner makes. Getting the basics right — including the often-overlooked question of what you pay in council tax during the works, and whether your band is even correct — is part of making sure the project adds up from start to finish.
