Great Job, by great Professional.
After my initial enquiry, JCS sparks replied. Jon from JCS answered all my questions and turned up on time, checked and repaired all my storage heaters. He even explained the principles of storage heaters to my tenant. He did a brilliant job, his fees are very reasonable and I can recommend him 100%.Verified reviewerJob location: NN16RRab G9.67 Electrician
