Why summer is the best time to get a heat pump installed

There’s something very British about remembering your heating when you can see your own breath indoors. Every year without fail, the first cold snap hits and suddenly everyone wants their heat pump installed or serviced. The phones go crazy, the diaries fill up, and if you’re left crossing your fingers that your old boiler will hold on a little longer. 

If this sounds familiar to you, read on. Summer is genuinely the best time to get a heat pump installation, repaired or serviced, and most people are sleeping on it. 

Why summer installs just make sense

The good news is there are plenty of reasons to get it sorted now, and none of them involve waiting until the winter months. Let’s walk through them.

Skip the queue

Installers are especially busy in the autumn and winter. Everyone wants their heating sorted as the cold weather arrives, which means longer waiting times, less flexibility on dates, and engineers who are stretched thin. 

Book in summer, and you’re much more likely to get a slot that suits you. The job can be done on your timeline, your installer has time to talk you through everything properly, and you get a thorough handover so you can understand your system before you need it. 

Groundwork is easier

If you’re going for a ground source heat pump, the ground conditions in summer make a real difference. Dry, firm ground is much easier to dig through and work with than waterlogged, heavy or frozen soil in autumn. It’s quicker, cleaner, and generally a smoother job all round. 

Even for air source installs, dry weather and longer daylight hours make outdoor work easier for the engineers. 

A gentle introduction to running costs

Your first months as a heat pump owner will be in the summer, when the system isn’t working as hard as it would in the colder months. It’ll likely just be ticking over to keep your hot water topped up. Your bills will be lower, which means you can slowly adapt to a new way of heating your home without being thrown straight into peak winter demand. 

This also gives you time to iron out any teething issues. If something needs a small adjustment after installation, it is much easier to get an engineer out in summer when diaries are quieter. You can get everything working exactly as it should before you actually need it.

Ditch the old boiler on your own terms

Swapping out a boiler is a big change for your home. Do it in summer, and you’re making that decision calmly, without a cold house making the situation feel urgent. You’ll be in control of the timing, and if things don’t go to plan, you won’t be struggling with chilly nights when you need your heating the most. 

Your heat pump can cool your home too

As heat pump tech advances, more models are emerging that can cool home as well as heat it. They do this by working in reverse, extracting warm air from inside your home and pushing it outside. It is a great option for people who want to keep cool in summer without the cost of a full air conditioning system.

By installing in summer, you can put this to the test straight away and keep things comfortable on those sticky August nights.

Make sure to ask your installer whether cooling is an option for the system they are recommending.

Ready to beat the rush?

All in all, summer is by far the smartest time to get a heat pump installed. The diaries are quieter, there are no stock shortages or October panics, and you get months to settle into your new system before the winter arrives.
