On 7 August 2026, the British Retail Consortium warned that retailers installing air conditioning and other store improvements to cope with extreme heat can face higher business-rate liabilities because the work may increase a property’s rateable value.
The issue is not a separate new “air-conditioning tax”, but the BRC argues that the existing rating system can effectively penalise retailers for investing in their stores.
→ Latest retail impact: UK footfall fell 2.1% year on year in July 2026, while high-street footfall dropped 3.8% as prolonged hot weather discouraged shopping trips.
→ Tax position: qualifying improvements such as adding air conditioning can receive Improvement Relief, but in England the protection against the resulting higher bill generally lasts only 12 months.
Why Is the BRC Calling Retail Cooling Equipment a Tax Penalty?
The dispute centres on how business rates respond when a retailer improves a physical shop.
British Retail Consortium chief executive Helen Dickinson said increasingly extreme temperatures are pushing retailers to invest in measures including air conditioning and more efficient refrigeration. She argued that business rates can then “punish” stores making those investments.
Reporting on the BRC warning also quoted director of business and regulation Tom Ironside explaining that improvements can increase a property’s rateable value and therefore potentially increase its rates liability. That is the basis of the BRC retail cooling equipment tax penalty argument.
It does not mean the Government has introduced a specific tax on air-conditioning units. Instead, the concern is that installing equipment which improves a commercial property can affect the valuation on which business rates are calculated.
The Government’s own Improvement Relief guidance specifically lists adding air conditioning as an example of an improvement that may increase rateable value.
How Can Air Conditioning Increase Business Rates?
Business rates are closely connected to a commercial property’s rateable value.
The Valuation Office Agency assesses rateable values, while local authorities use those valuations alongside the applicable multiplier and reliefs to calculate bills.
Official VOA valuation guidance states that plant and machinery included in a valuation can include air conditioning, heating, CCTV and sprinklers.
So the sequence can work like this:
- A retailer installs new air conditioning.
- The improvement changes the characteristics or value of the premises.
- The VOA determines whether the work increases the property’s rateable value.
- If it does, the higher valuation can eventually feed into the business-rates calculation.
- Any applicable relief may temporarily reduce or delay the additional liability.
Importantly, a higher rateable value does not automatically mean the business-rates bill rises by exactly the same proportion. Multipliers, reliefs and other circumstances also affect the final bill. GOV.UK makes this distinction clear in its guidance on the 2026 business-rates revaluation.
Does Improvement Relief Solve the Problem?
Only temporarily in qualifying cases.
In England, Improvement Relief was introduced from 1 April 2024 to prevent eligible occupiers immediately paying higher rates because of qualifying improvements.
The rules can cover additions such as new heating, air conditioning or CCTV. Eligible businesses generally receive relief from the increase attributable to qualifying works for 12 months from completion. The scheme is currently scheduled to run until 1 April 2029.
That explains the BRC’s objection: the investment may have a useful life of many years, while the protection against the resulting increase in rates lasts only one year.
A Simple Example
Suppose a retailer installs a new cooling system and the VOA certifies that the qualifying work has added £10,000 to the property’s rateable value.
If all Improvement Relief conditions are satisfied, the certified increase can effectively be excluded when calculating the relevant rates liability during the 12-month relief period.
After that period ends, the higher rateable value may feed into the normal rates calculation.
The exact extra cost cannot be determined from the £10,000 figure alone because the applicable multiplier and other reliefs must also be considered.
Why Has the Issue Become More Urgent During the 2026 Heatwaves?
Retailers are facing pressure from both sides: hotter stores may require more investment, while extreme heat can simultaneously reduce customer traffic.
The latest BRC-Sensormatic figures reported for July showed total UK footfall down 2.1% year on year. High streets performed worse, falling 3.8%, while London footfall was down 5.3%. The July retail footfall figures linked the weakness partly to exceptionally hot conditions.
That matters because physical retailers already carry substantial property-related costs. Coverage of the wider pressures facing high-street retailers has highlighted how business rates, energy, wages, rents and weakening footfall can combine across large store estates.
For a retailer deciding whether to spend heavily on air conditioning, the calculation therefore extends beyond the purchase and electricity costs. Management may also have to consider whether the improvement changes the property’s future rates liability.
Is This Rule the Same Across the UK?
No. Business rates are devolved, so retailers should not assume one set of rules applies identically across England, Wales, Scotland and Northern Ireland.
The BRC warning concerns the wider UK retail environment, but the detailed tax treatment depends on where the property is located.
England has the Improvement Relief framework described above. Wales has its own closely related 12-month non-domestic rates Improvement Relief scheme, which can also cover additions such as air conditioning and other rateable plant and machinery.
Scotland operates its own devolved non-domestic rates framework, with valuations undertaken by Scottish Assessors rather than the VOA. Scottish Government guidance on non-domestic rates confirms that its arrangements differ in detail.
Retailers planning significant cooling investments should therefore check the rules applying to the specific property rather than relying on a UK-wide assumption.
Why the BRC’s Warning Matters Beyond Air Conditioning?
The argument touches a bigger question about how the tax system treats investment in bricks-and-mortar businesses.
England introduced new retail, hospitality and leisure multipliers from April 2026, including lower multipliers for qualifying properties with rateable values below £500,000. Yet property improvements can still alter the underlying rateable value on which the system operates.
The concern is particularly sensitive for physical retailers competing with online businesses. This issue has already been examined in coverage of the UK low-value parcel tax reforms and the debate over how tax policy affects domestic high-street retailers.
It also follows other disputes about the 2026 rating system, including concerns around the treatment of hospitality premises discussed in our analysis of the England cafe business-rates changes.
Cooling equipment has therefore become another example in a broader argument: should investment that makes physical premises more useful, resilient or energy-efficient result in a higher property-tax base?
What Happens Next?
The BRC is using the latest heatwave and footfall figures to strengthen its case for further business-rates reform.
There is no confirmed announcement, as of 8 August 2026, that the Government will exempt retail air-conditioning installations from rateable-value assessments or extend Improvement Relief beyond its current framework.
For retailers, the immediate practical step is to assess potential business-rate consequences before committing to major property improvements. That means considering not only installation and running costs, but also whether the work could change the rateable value, whether it qualifies for Improvement Relief and what happens after the relief ends.
The BRC’s warning is therefore best understood not as news of a newly introduced air-conditioning tax, but as a renewed challenge to an existing feature of the business-rates system.
FAQs
Is there a new UK tax on shop air conditioning?
No, there is no separate new tax specifically charged on shop air conditioning. The controversy concerns the existing business-rates system, under which adding air conditioning can increase a property’s rateable value and potentially its future rates bill.
How long does business-rates Improvement Relief last?
Qualifying Improvement Relief generally lasts 12 months from completion of the eligible works in England. After the relief period expires, the increased rateable value may affect the normal business-rates calculation.
Does every air-conditioning installation increase business rates?
Not necessarily. The VOA determines how changes affect an individual property’s rateable value. The final rates bill also depends on the relevant multiplier, other reliefs and the circumstances of the property.
Can retailers challenge their rateable value?
Yes. Businesses in England and Wales can check property information and use the VOA process to report changes or challenge a valuation where appropriate. GOV.UK advises ratepayers to review the information held about their property if they believe a valuation is incorrect.
