As an official Octopus Trusted Partner, we don’t just install systems — we design complete heating solutions tailored to your property.
Depending on your home, we may recommend:
Not every home is the same — and your heating system shouldn’t be either.
Start by telling our friendly team a few simple details surrounding your home. We'll provide a rough estimate and explain what type of system we recommend for your property and why.
One of our heat pump specialists will carry out a detailed home survey to assess insulation, radiators and heating requirements. We'll then design a Cosy heat pump tailored specifically for your property - no pressure just clear honest advice.
Once you're happy to go ahead, our experienced installation team will fit your new Cosy heat pump - usually within a couple of weeks. We handle everything from set up, commissioning and hand over ensuring your home is warm, efficient and ready to enjoy for years to come.
From first quote to final install, we focus on honest advice, expert workmanship, and long-term value — powered by the latest technology and a commitment to exceptional customer care.
The Octopus Cosy Heat Pump is a next-generation air source heat pump designed specifically for UK homes.
It’s compact, extremely quiet, and built to deliver reliable heating and hot water while keeping running costs low — especially when paired with the Octopus Cosy tariff.
As an approved Cosy installer and trusted Octopus partner, OHMS Renewables ensures every system is correctly designed, installed, and optimised for maximum efficiency and savings.
The Cosy tariff provides three discounted off-peak windows every day:
04:00 – 07:00
13:00 – 16:00
22:00 – 00:00
That’s 8 hours of cheaper electricity, typically around 50% below the standard day rate.
The peak period runs from 16:00 – 19:00, where electricity costs are higher, while all other hours sit at the standard rate.
A properly configured Cosy Heat Pump can automatically prioritise heating and hot water during cheaper periods.

Yes — and this is one of the most powerful setups available.
You can:
OHMS specialises in designing fully integrated solar, battery, and heat pump systems for maximum savings.
Electricity used between 16:00 – 19:00 is billed at the higher peak rate.
However, a properly configured Cosy Heat Pump can pre-heat your home and hot water before peak hours, reducing the need to run during expensive periods.
This is where professional commissioning makes a major difference.
Cosy is a variable tariff, meaning prices can change with the energy market.
However:
Smart scheduling still provides strong savings
