Why Radlett homes get hot
Radlett's housing runs large: substantial detached family homes on generous plots, many of them extended over the years with loft conversions and glazed kitchen additions. Big houses bring big summer problems — bedrooms under the roof that hold their heat long into the night, a home office that faces the sun all afternoon, and open-plan rear extensions that behave like greenhouses in July. If you work from home rather than commuting from Radlett station, you will already know exactly which room becomes unusable by mid-afternoon.
One genuine advantage here: the gardens. Radlett plots tend to be big, so finding a discreet spot for an outdoor unit — down a side return, or tucked behind planting at the rear — is usually far easier than on tighter streets elsewhere. On price, we would rather not pluck a figure out of the air for a page like this; what an installation costs depends on the number of rooms, the pipe runs and the state of your electrics. Our cost guide walks through what actually drives the price. One thing worth knowing: a modern split system is a reversible air-to-air heat pump, so it heats as well as cools — but government heat pump grants generally cover air-to-water systems only, so check the current rules rather than budgeting for a subsidy.
Planning and electrics in WD7
Before fixing any external unit, check whether your property sits in a conservation area or is listed — a quick call to Hertsmere Borough Council settles it. Don't assume either way: checking costs nothing, and undoing an installation costs plenty.
Electrics matter too. A house that has been extended two or three times doesn't always have a consumer unit that kept pace, and it is far better to find that out before an installer quotes than on the day they arrive. An EICR (Electrical Installation Condition Report) from a qualified electrician tells you where you stand. There's more in our guide to whether your home's electrics can handle air conditioning. And if you're in a flat, you'll need your freeholder's consent for anything fixed to the outside of the building.
Where Coolhouse is up to in Radlett
A straight answer: our vetted installers currently work in St Albans and Harpenden, a few miles up the road. We haven't yet vetted anyone for Radlett itself, and we won't pretend otherwise or promise a fast quote we can't stand behind. We're building our Radlett network now. If you register your interest, we'll tell you honestly where we've got to — and you'll be the first to know when we have installers here we'd trust in our own homes.
