Why Enfield's interwar homes run hot
Much of the borough went up in one great push between the wars, when the Underground reached Southgate and Oakwood and the fields either side filled with semis. Those houses have real virtues — cavity walls, decent gardens, generous bay windows — but the bays and wide west-facing rears catch a lot of afternoon sun, and the heat rises into the bedrooms and sits there. Add a loft conversion, common across Palmers Green and Winchmore Hill, and the top room is often the warmest in the house. In the Edwardian terraces around the Lakes Estate, and anywhere close to Green Lanes or the A10, there's the extra catch that opening windows at night means traffic noise.
For most of these houses the realistic option is a split system — one indoor unit, one outdoor unit — or a multi-split covering several rooms. What it costs depends on the house itself: how far the pipework has to run, where the outdoor unit can sit, whether access needs scaffolding. Rather than quote a number that might be wrong for your street, our guide to air conditioning costs sets out what installers actually charge and why. Worth knowing: a modern split is a reversible air-to-air heat pump, so it heats in winter as well as cooling in summer — though air-to-air systems sit outside the Boiler Upgrade Scheme, which covers air-to-water heat pumps only.
Conservation areas, flats and older wiring
Enfield has some genuinely protected pockets — parts of Enfield Town around Gentleman's Row, Southgate Green and the Lakes Estate in Palmers Green sit within conservation areas. If you're in or near one, check with the council before fixing an outdoor unit to an external wall rather than assuming either way. Flats and leasehold houses almost always need the freeholder's consent too.
Electrics matter as well. Plenty of interwar homes are still running on consumer units fitted decades ago, and an installer may want that upgraded before adding a dedicated circuit. An electrical condition report — an EICR — tells you exactly where you stand before anyone quotes. Our guide to whether your electrics can handle air conditioning explains what to look for.
Where Coolhouse is up to in Enfield
Straight answer: we're not live in Enfield yet. Our first vetted installers are just over the border in Hertfordshire, so the borough sits right on the edge of where we work, and it's one of the areas we're building towards next. If you leave your details, we won't pretend a quote is coming tomorrow — we'll tell you honestly where we're up to, and match you with a vetted local installer as soon as we have one covering EN and N postcodes. You can start an estimate now so you're first in the queue when we do.
