We called in ABS after receiving a recommendation from a friend. We had a 30 year old boiler that had just stopped heating our property as winter was setting in. ABS came round and installed the new boiler within days of the initial call which we were very grateful for. We weren't oversold a boiler and didn't feel pressured into anything, which is quite a relief nowadays. After the installation and a little maintenance our central heating was better than ever and the change to a combination boiler improved the water pressure immensely. My wife commented that ABS were extremely polite and very considerate about noise and cleaning up after the installation.
We hired ABS to replace our back boiler, which was on it's last legs. Our house is an old Victorian era terrace that last had the heating looked at in the 80's. ABS suggested switching to a storage heater Combi boiler as we planned to convert the loft and wanted a new boiler with some oomph. ABS removed our existing storage and cold water tank in the loft and had the new boiler in without any inconvenience. The heating can cope with the recent cold snaps and we can run a couple of showers with piping hot water at the same time. ABS are highly recommended.
