Background

Suzanne lives in a 4-bed semi-detached house in Dublin. Built in 1999, it had a C1 BER when she moved in. That’s a decent starting point but it wasn’t the warm, efficient, low-running-cost home she wanted.

And she knew what she wanted and also what she didn’t want.

Suzanne wanted to add solar panels, replace the windows and bring in a more modern efficient heating system. What she didn’t want was to manage a lot of contractors to get the home energy upgrade works completed to a high standard.

"The bills were just going to be constantly increasing and become shockingly high. So as you get older, of course, you want to protect yourself from all of that."

The Challenge

In order to deliver a more comfortable, cost-effective and energy secure home, more than one energy upgrade would be needed, along with ancillary works.

The property ran on a mains gas boiler, with a solid fuel stove as secondary heating. The older double-glazed windows were letting heat escape. The attic had some insulation, but not enough. And there was no renewable energy of any kind.

That’s a lot of moving parts. Each upgrade usually means a different tradesperson, a different quote, a different grant application and a different set of dates to juggle.

This is further complicated when workmanship quality, warranties and a mountain of paperwork come into play.

The Solution

The solution was Ohk energy’s One Stop Shop service.

Suzanne gained a partner, one point of contact, through her newly simplified, warrantied and entirely managed home energy upgrade journey.

After completing a Home Energy Assessment and discussing Suzanne’s goals, household energy demands, budget, grant availability and more, Ohk energy made detailed and tailored home energy upgrade recommendations. This included:

  • 11kW air-to-water heat pump installation;
  • Solar panel installation (5.85kW system) with battery (8kWh);
  • New, more energy-efficient, windows;
  • Attic insulation;
  • Ancillary works including boiler decommissioning, insulating pipework, heating and solar controls, etc; and
  • Project management, independent follow-up BER, commissioning & handover, and more.

We looked after the grants too. Suzanne filled in her details and our team organised and chased the applications. At the time, the total grant value works out at over €15,000 (use our One Stop Shop Grant Calculator to see the latest grant values).

Speaking about her One Stop Shop experience with Ohk energy, Suzanne notes:

"I didn't have to organise anything...I mean it was marvellous."

The Results

Suzanne has peace of mind. She is now more energy secure, more protected against energy price hikes.

Her bills are lower, her home is warmer.

Additionally, she now has:

  • An improved BER: C1 to A2;
  • A modern, efficient heating system;
  • Less heat escaping her home;
  • Her own independent source of electricity;
  • Up to 8kWh of electricity available during power outages;
  • A substantially reduced carbon footprint;
  • No more gas bills;
  • Workmanship and product warranties; and
  • Ongoing support, if needed.

Speaking about the results, Suzanne said:

"The end result is that the house is toasty and warm all the time. I've fabulous new windows in, everything's insulated and Ohk provided me with that."
