Our heat pump guarantee

Once you book your installation, we take care of everything else, including the electrical work, so our service is as stress-free for you as possible. We can also carry out all maintenance work and upgrade your existing heat pump.
We won’t leave a mess
Installing a heat pump does require making a certain amount of mess, but you won’t be left to clear it up afterwards. Before we start work, we place drop cloths on your floor coverings to ensure no damage occurs. We also move your furniture out of harm’s way and replace it when we’ve finished. When the job’s complete, we vacuum up any dust and debris, too.
You always know what’s happening
We know how frustrating it is to not know what’s going on if there’s a delay with your installation. If we are held up for any reason we’ll call and let you know exactly what’s happening so you can go about your day with the minimum of hassle and disruption.
