We come round and give you an honest calculation of what will bring you the most. Free and with no obligation.
Where it goes wrong
Why does everything take so long, and why does nobody call back?
That's the most common complaint in this industry. Months of waiting for an installation. A breakdown nobody comes out for. And too many companies talking you into something expensive that saves you a hundred euros up front and costs you a hundred and fifty more down the line.
That's why BKA was founded.

FAQ
Frequently asked questions
Nothing. The survey at your home is free and comes with no obligation. We look at what's going on and do the honest maths on the spot.
That depends on your house, your usage and what we install. With a hybrid heat pump it quickly adds up, especially in winter. During the free home survey we calculate it using your figures, not an average.
Honest answer: it differs per house and per system. That's why we don't work with standard prices on a website, but calculate it at your home. You get a clear quote with no small print.
After the survey you'll know exactly where you stand, including the timeline. We tell you honestly when we can do it, and we keep our appointments.
Because you get savings that actually materialise. We call back, we come round, we do it right first time, and you have one point of contact for your entire installation.
