Why Chelmsford homes overheat
Essex is one of the warmest, driest corners of the country, and Chelmsford sits in the middle of it. When a heatwave arrives, the city feels it early and holds onto it late.
The housing stock doesn't help, from either end. The Victorian terraces near the centre have solid brick walls that soak up heat all day and release it into your bedroom all evening, long after the sun has gone down. The newer estates across CM1, CM2 and CM3 have the opposite problem: modern homes are built airtight and heavily insulated to keep heat in, which works a treat in January and turns the upstairs into a greenhouse in July. Different houses, same sleepless night.
A properly installed split system sorts both, and because it's a reversible air-to-air heat pump it heats the same room efficiently in winter too. If yours is one of the older terraces, our Victorian homes guide covers the quirks — including checking with the council before an outdoor unit goes on the wall in a conservation area.
Sort the electrics first
Before pricing units, glance at your fuse board. Chelmsford's newer estate homes are usually fine, but plenty of the older terraces are still running on ageing consumer units, and a split system wants safe, modern electrics behind it.
It's rarely a dealbreaker. An electrical condition report (EICR) usually costs a couple of hundred pounds, and if the board does need replacing, that's a routine job a decent installer will flag at survey rather than spring on you later. Our guide on whether your electrics can handle AC walks through it.
What it costs, and where we've got to
As a rough guide, a wall-mounted split for a single room usually comes in somewhere between £1,500 and £3,000 fitted, depending on the unit and how far the pipework has to run. A multi-split covering three or four rooms is more, typically £3,500 to £7,000 — though most families only cool the two or three rooms that actually get hot.
Now the honest bit: we're just opening in Chelmsford, so we don't have active local installers yet. We're vetting and onboarding them now. Leave your details and you'll be first in the queue — as soon as a vetted installer covering your postcode comes on board, we'll match you. No call barrage, no chasing, no obligation.
