Allow us to introduce ourselves
We are LS1 Boiler Installation, a friendly, family-run and ethical boiler and central heating company based in South West London. We started life as Landlord Safety 1st back in 2005, with a focus on boiler servicing and landlord gas safety inspections. As our reputation grew we decided to meet the growing demand and expanded our services to provide full central heating and boiler installations.
In 2007 we relaunched as LS1 Boiler Installation and we are now one of London’s largest boiler and central heating companies. We owe our success to our army of happy customers who continue to spread the word about what a great job we do.
When it comes to boiler installations, we really are the ‘A’ team because it’s what we do day in and day out. It also means we are bang-up-to-date on all the latest innovations and new technology like the fantastic Nest smart control that makes managing your heating and hot water a doddle.
