John

Eastbourne Homeowner
The work undertaken by the engineer and others was excellent and I cannot be better pleased at this time. The items needed for the installation arrived on good time the day before and the actual work itself, to me, was efficient as well as clean and tidy. Thankyou for that.

As an 'all round job'; most satisfactory!

Loggerheads Homeowner
Much easier than expected.
Very pleased with every aspect so far. Everything went to time and was all tidy and cleanly done. Loved the carpet protection!
We are still getting used to controlling things from the computer but works a treat. No doubt winter conditions will be a fairer test.
