We found them prompt efficient and competitive with their quote. We took their recommendation of a bigger boiler and the lid has allowed us to extend our system over the past 5 years.
Their service team are very capable and worked in very dirty tight spaces without complaint. Unlike a gas installer, they didn’t break anything or interfere with our other trades.
We have had no issues and changing our thermostat to a remote Nest thermostat was no issue.
We can’t recommend them highly enough. Happy to provide this reference from a happy and long standing customer.
