About Coastal Mechanical Services
Commercial heating, plumbing and mechanical installation across East Sussex, Surrey and Kent, from a small team with more than 20 years behind it.
Our story
Based in Pevensey
Coastal Mechanical Services Ltd was established in 2021, but the small team of qualified professionals behind it has more than 20 years of experience in heating and plumbing for commercial and industrial companies across Sussex, Surrey, Kent and beyond.
That time bought a working knowledge of which products and brands actually last, and which solutions give a client real value rather than the biggest invoice. We deliver the whole chain: consultancy, design, supply, installation and contract service agreements.
Energy efficiency
The requirement to install efficient systems that protect people and the environment can feel like a financial burden, and with ESG reporting it can no longer be put off. We size and specify against the real load so the upgrade pays for itself rather than simply costing money.
Personalised customer service
A small team means you deal with people who know the job. No matter the size of the project, we work to your precise requirements and keep the communication open from survey through to sign-off.
Gas Safe engineers
Commercial and industrial heating is complex work and you need to know who is doing it. Our engineers carry more than 20 years with commercial boilers and industrial heating systems, and every technician is Gas Safe registered.
