Babergh: cooling planning decisions

Babergh has issued 39 cooling determinations, on applications that say so in their own wording - 36 approvals against 3 refusals. Enough to describe, not enough to be definitive.

Babergh's record holds 13 more that never reached a determination, whether because they remain live or because the applicant pulled them. Everything below excludes them, so the rate describes determined cases only.

92.3% of the 39 decisions were approvals, a figure covering all development types and 7 householder applications. The refusals behind the remaining share are real rather than rounding.

The scope matters as much as the number. Commercial and mixed-use plant makes up a large share of any council's cooling caseload, so an all-development rate is a weaker guide to a domestic application than its size suggests.

We stop short of a householder-only percentage for Babergh. At 7 decided householder applications the sample is too thin, and a rate drawn from it would read as far more certain than the evidence allows.

The air-to-air heat pump, which heats as well as cools and is the only equipment that can be permitted development on a house, appears in none of Babergh's decided applications by name. Nationally the count is similarly close to zero: this is a category planning departments have barely met.

There is little to choose between the two here: 92.7% of the 55 decided applications mentioning an air-source heat pump were approved by Babergh, a whisker from its cooling-plant record.

These two figures are never added, averaged or read as one. Most air-source schemes heat rather than cool, and an application mentioning both sits in both counts.

The distinction is the whole point: an air-to-air heat pump, which heats as well as cools, can be permitted development on a house, and a cooling-only unit cannot.

Since 2025-05-29, England's permitted-development rules let a house fit an air-to-air heat pump, which heats as well as cools, without a planning application in many cases, within set size, siting and noise limits. A unit that only cools has no equivalent route and needs a full application whatever the property.

That is why the decisions above matter more than they would have before the change. Every cooling-only installation now crosses a planning officer's desk, so the council's posture is not background information, it is the decision.

Flats are the sharpest exception, here as everywhere in England: the permitted-development right for an outdoor unit belongs to the house rather than to a flat within it, so a flat will usually need freeholder or managing-agent consent as well as planning permission.

What those refusals were FOR is a national question at the volume of officer reasoning currently published, not a council-level one, and we do not pretend otherwise. Both findings are set out with their sample sizes: why cooling applications get refused and the conditions councils attach to an approval.

Every council we can publish a figure for is listed on the council index.

Applications are identified from their own description, so every count on these pages means applications mentioning cooling equipment, not every cooling installation in the area. An application that fitted the same kit but described it as external plant is not in these figures, which makes them a floor on activity rather than a census.

Each application is assigned to Babergh through the postcode on the application itself. Of the 52 applications recorded for this authority, 100% carry a location we could resolve; nationally 1738 of 19260 applications could not be tied to a district at all and sit outside every figure on this site rather than being quietly assigned somewhere.

What this page cannot tell you is what will happen at your address. It has no view of your elevation, your neighbours' windows, whether your home sits in a conservation area, or whether it is a listed building - and a neighbour's approval settles none of those. This is indicative guidance drawn from public planning records, not legal advice: confirm the final position with your Local Planning Authority before you install.
