Why Newham homes overheat
Newham has seen a huge amount of new building over the last couple of decades. Stratford around the Olympic Park, Canning Town and the Royal Docks are full of apartment blocks that didn't exist a generation ago, and they're usually well insulated and airtight — great in January, less great in July. Many flats are single-aspect, so there's no way to pull air through, and big glazing facing the afternoon sun can leave living rooms and bedrooms uncomfortable for weeks. If you've spent a summer high up in a newer Stratford or Canning Town block, you'll know exactly what we mean.
The older end of the borough is different. East Ham, Plaistow, Forest Gate and Manor Park are mostly Victorian and Edwardian terraces — often cooler downstairs, but back bedrooms and loft conversions can be stifling by evening.
On cost, we're not going to put a number here and pretend it applies to your home. Flats vary a lot: where the outdoor unit can go, how far the pipework has to run and what the freeholder allows all move the price. Our cost guide walks through what actually drives a quote. It's also worth knowing that a modern split system doubles as an air-to-air heat pump, so the same unit can heat the room in winter.
Freeholders, planning and older wiring
Because so much of Newham lives in flats, the first hurdle is usually legal rather than technical: leaseholders almost always need the freeholder's consent before an outdoor unit goes on a balcony or external wall. Get that agreed in writing before anyone books a survey. Parts of the borough sit in conservation areas too, so if yours does, check with the council before fixing anything to the outside of the building rather than assuming it's fine.
In the older terraces, wiring is the thing to look at. Some still run on ageing consumer units that need attention before air conditioning can be added safely — a straightforward thing for an electrician to assess, and our guide on whether your electrics can handle air conditioning explains what to look for.
Where Coolhouse is up to in Newham
Straight answer: our vetted installers are currently in Hertfordshire, and we haven't yet signed anyone in Newham. We're building our East London network now, and we'd rather say that plainly than promise a quote we can't deliver this week.
If you're in Stratford, East Ham, Canning Town or anywhere else in the borough, leave your details and we'll tell you honestly where we're up to — then match you with a vetted local installer as soon as one comes on board. Early interest also tells us where to recruit first, so it genuinely helps.
