Average review rating A Trusted Local Name In Edinburgh
Culbertson Renewables Ltd is a trusted heating and renewable energy specialist based in Portobello, Edinburgh. Our engineers bring over 20 years of experience in the trade, from traditional plumbing and heating through to the renewable technologies now reshaping how Scottish homes are heated.
Today our engineers install and maintain everything from gas boilers and bathrooms to air source heat pumps, solar panels, battery storage, underfloor heating and district heat networks. Whether it is a single radiator or a heat network serving an entire development, the same accredited team sees the job through.
Greener Heating, Without The Jargon
At the heart of what we do is a simple idea: combine cutting-edge renewable energy expertise with outstanding customer service. Lower bills and lower carbon should not come with a confusing sales process.
So we explain the options in plain English, tell you honestly what will and will not work for your property, and put it in writing before anyone lifts a tool. That approach is why so much of our work comes from repeat customers and recommendations across Edinburgh and the Lothians.
