Air conditioning in Hackney: what you can install and what the grant covers
Hackney has 35 conservation areas, four in five households in flats, and one of the highest shares of council and ex-council housing in London — which means a lot of storage heaters. That last fact matters more than you'd think: it's exactly what the government's £2,500 air-to-air heat pump grant was created to replace, with a unit that cools in summer too.
See if the £2,500 grant applies to your home — five questions.
Check my eligibilityDo you need planning permission in Hackney?
For houses, usually not: one air-to-air heat pump that heats as well as cools is permitted development in England — under 1.5 m³, meeting the MCS noise standard, and not mounted above ground-floor level on a wall facing the street. Hackney's own guidance points the same way, asking that units sit where they can't be seen from the road.
Cooling-only air conditioning is a different story: it always needs an application, and Hackney's emerging planning guidance takes a dim view of it. The practical takeaway is the same one the grant pushes you towards anyway — choose the unit that heats first and cools second.
Conservation areas in Hackney
De Beauvoir, Stoke Newington, Victoria Park, Clapton Square — 35 in all, plus around 1,300 listed buildings.
Inside a conservation area, street-facing walls and roofs are off-limits without permission, so rear elevations and courtyards are the standard route. Worth knowing: a few Hackney conservation areas — including De Beauvoir — carry extra Article 4 restrictions that remove more permitted development rights than usual, so placement gets checked case by case there. Your installer handles that check.
Flats and leaseholds
Around 81% of Hackney households live in flats, and two in five rent from the council or a housing association.
Flats don't get permitted development rights, so expect a planning application plus freeholder consent — for social tenants that conversation goes through the landlord, and for leaseholders in ex-council blocks, through the council's leasehold team. Renters of any kind: the grant follows the property, so share your checker result with your landlord.
The £2,500 grant in Hackney
More than 14% of Hackney households heat with electricity only — among the highest rates in inner London, concentrated in estate blocks on storage heaters.
The £2,500 air-to-air grant is ring-fenced for precisely these homes: properties replacing direct electric heating. One unit that heats all winter for less than storage heaters cost to run, and cools in July. Your MCS-certified installer applies through Ofgem and knocks £2,500 off the bill.

Check my eligibilityFrequently asked questions
Do I need planning permission for air conditioning in Hackney?
Houses usually don't for an air-to-air heat pump placed out of sight of the road; cooling-only units always need permission. Flats — 81% of Hackney homes — need an application plus freeholder consent.
Can I install air con in a Hackney conservation area?
Usually yes, on a rear elevation or courtyard placement. Note that some areas, like De Beauvoir, have extra Article 4 restrictions, so check before fixing anything to a street-facing wall.
Can flats in Hackney get the £2,500 grant?
Yes, if the flat is replacing direct electric heating — over 14% of Hackney households heat this way, mostly storage heaters in estate blocks. Freeholder consent is needed for the external unit.
Who applies for the grant?
Your MCS-certified installer applies to Ofgem on your behalf and deducts £2,500 from your quote. You never fill in a government form.
