Heating in DorsetLocal knowledge matters
From the Lizard to Lyme Regis, sunny Salcombe to the wilds of Dartmoor, the bumpiest farm tracks to the narrowest cobbled streets: our surveyors and engineers have spent years working in the communities we serve.
That means we understand your home, the weather it stands up to, and what it takes to heat it properly.

Built for our climate
The South West has its own climate. High humidity, salt air and frequent damp mean a cheap radiator bought elsewhere simply won’t last.
Every radTherm radiator contains a patented heat-retention core, fully sealed against coastal moisture, with outdoor-grade powder coating to resist salt air.

Cornwall is our home county and where our journey began. From the far west at Penzance and the Lizard to Launceston on the Tamar, we cover the length of it every week: granite cottages, slate-roofed farmhouses, holiday lets and modern estates.
From Plymouth’s streets to isolated Dartmoor farmhouses, Exeter’s terraces to the thatched cottages of the East Devon coast, no two Devon installs are the same. Rural homes with no mains gas are where electric heating makes most sense.
Taunton, Bridgwater and Yeovil, the Levels, and out to Exmoor. Many Somerset villages are off the gas grid, which makes modern electric heating a practical choice.
Market towns, the Jurassic Coast and rural villages, many still heated by oil. We’re used to Dorset’s older stone-built homes, where a careful, tidy install matters.
What our customers say
Real customers, named, from across the region.
“Adam the plumber and Shaun and Steve the electricians were very polite and good fun. They left the place like they hadn’t been in. The bungalow now has warmth when we want it, and my bills have also dropped.”
Rob Harris Cornwall · radiators and Sunamp“We were pleasantly surprised that we didn’t need as many radiators as we thought. Yet still had enough to heat all the rooms exactly as we wanted.”
Louisa Chanter Tavistock, Devon“When everything was finished, our flat was left as if no work had taken place. We are absolutely delighted.”

The quickest way is to call us on 01209 714600 or send us an email. We cover Cornwall, Devon, Somerset and Dorset. If you’re just outside, it’s still worth asking: if we can’t help, we’ll put you in touch with a carefully selected installer near you.
No hidden travel surcharges anywhere we cover on the mainland South West. Your written quotation covers the radiators, the installation and any extra work we’ve agreed, and if anything about your location affects the job we’ll tell you before the survey.
It depends on the time of year. In winter it can take a week or two; in quieter months we can often visit within a few days. Call us and we’ll give you the next available dates.
