Why Epsom homes get uncomfortably warm
Epsom's housing is older than the commuter-town label suggests. The centre still has Georgian and Victorian stock — solid brick walls, high ceilings and, in plenty of cases, original single-glazed sashes — and around it sit street after street of large interwar semis with generous gardens. Solid-walled period houses hold on to heat once a warm spell settles in: the brickwork soaks it up over several days and releases it slowly through the night, which is why bedrooms stay stuffy long after the evening cools off. The interwar semis have their own problems — wide south-facing bays that trap sun all afternoon, and the loft conversions many families have added, which tend to be the hottest rooms in the house by some distance.
For most of these homes the practical option is a split system: an outdoor unit paired with one or more indoor units. The same kit works in reverse as heating in winter, because a modern split is an air-to-air heat pump. We won't put prices on this page, because they depend heavily on the individual house — our guide to air conditioning costs in the UK sets out realistic ranges and what pushes them up or down.
Planning and electrics — check these before anyone quotes you
Two things catch Epsom homeowners out. The first is planning. Parts of the older town sit within conservation areas, and some period properties are listed, which affects where — and whether — an outdoor unit can go. Check with Epsom & Ewell Borough Council before anything is fixed to an external wall, and don't let an installer assume it's fine. If you're in a flat or a leasehold house, you'll usually need the freeholder's consent as well.
The second is electrics. Victorian and interwar homes often still have older consumer units that need attention before a new circuit can be added. It's worth understanding before you get quotes — our guide on whether your home's electrics can handle air conditioning explains what an electrician will look for.
Where Coolhouse is honestly up to in Epsom
Straight answer: we don't yet have vetted installers working in Epsom. Our vetted network currently covers St Albans and Harpenden in Hertfordshire, and we're building it out from there. We won't pretend someone can be at your door in KT17, KT18 or KT19 next week, because they can't yet.
What we can do:
- Take your details and tell you plainly where we're up to in Epsom — no chasing sales calls.
- Let you know as soon as we've vetted installers who genuinely cover the area.
- Give you straight guidance on costs, planning and preparation in the meantime, so you're ready to move when we are.
If that's useful, leave your details here and we'll be straight with you.
