Why Essex homes run hot
Essex sits in one of the driest, sunniest corners of the UK, and much of its housing was never designed with hot weather in mind. The older terraces around central Colchester and Southend were built to keep heat in, not let it out. The 1930s semis along the commuter lines through Brentwood and Shenfield often have big south-facing bay windows that turn front rooms into sun traps by mid-afternoon. And the large new-build estates around Chelmsford and Basildon have the opposite problem: they are so well insulated and airtight that once summer heat gets in, it has nowhere to go. Top-floor bedrooms and loft conversions usually suffer worst.
A modern split-system air conditioner earns its keep at both ends of the year. It is a reversible air-to-air heat pump, so the same unit that cools a stuffy bedroom in July can heat it in January, and it does so more efficiently than a plug-in electric heater.
The checks worth doing before you buy
- Prices vary a lot with the property and the number of rooms, so rather than quote a figure that may not match your home, our cost guide explains what an installation involves and what moves the price up or down.
- Older homes — pre-war terraces and 1930s semis especially — sometimes need electrical work before an installer will fit anything. Our guide to whether your electrics can handle air conditioning explains what to check and who to ask.
- If your home is listed or sits in a conservation area — parts of central Colchester, for example — speak to the council before fixing an outdoor unit to the wall. Do not assume it is fine.
- Flats, from the blocks along the Southend seafront to newer apartments in Chelmsford town centre, almost always need the freeholder's consent first.

A straight answer: our vetted installers are currently in Hertfordshire. We have not yet signed installers in Essex that we would put our name behind, and we will not pretend otherwise.
