What our customers say

“CSM provided us with a detailed proposal for a new boiler and a heating system upgrade using the most appropriate components currently on the market. The work was completed within two weeks of their first visit and the standard of workmanship was peerless. Connor and Callum were well-organised, tidy and very neat, explaining the system changes and upgrades to us at every stage. No missed appointments, no mess, no demands for upfront payments. CSM are very straightforward and knowledgeable about all types of heating systems, highly recommended. Five out of five stars. ”
