Great website. Very quick delivery. A very positive description.
Great product, great service. What more can I say.
My heating programmer went U/S AFTER 10 years, that replaced after original installed 36 years ago. My heating engineer tried his suppliers that it could not be obtained but took about 3weeks to tell him. Said would need latest programmer with additional wiring. Could be costly. My electrician man located correct replacement, Delivered to door in 48hrs. Job done same day. House warm again. EXCELLENT SERVICE. SUGGEST USE WITH CONFIDENCE
