Had our lnstallation done last week ? After having a telephone call my husband agreed to a visit. Jon Wilson came to see us ,very impressed with the sales side very professional,not ***** at all ,explained everything ,took a few photos . Fitters came a few day later very clean and tidy removed a few items from the loft and did the job . Left after a few hours all was clean and tidy .very impressed with the result so far and hoping for a little saving on our heating. Thankyou
