Ratings say it all.
When had boiler problem contacted Emma and between us quickly resolved it (was just low water pressure common at this time of year);
Only one minor thing was that at end of week (which was glorious weather wise) tried to put heating on a wet and damp night for 1 hour, but thermostat kept switching itself back to 7deg after about 5 minutes each time.
Not sure why, but would have been issue in colder weather!
But overall, just what I needed and all I wanted
