SEM Facilities provide commercial gas and commercial heating installations, maintenance and periodic service to a wide variety of properties under the aegis of Mitie.


The DFS Furniture chain’s branch in Aylesford, north west Maidstone, Kent, had a gas heating system installed before realising that there was no gas supply in the locality. The gas supplier would happily have obliged, but installation of a new gas main would have come in at the princely sum of £100,000.

Mitie rely on SEM facilities and trust our judgement, hence handing the problem over to us to solve.


Our recommendation was to suggest the installation of LPG (Liquefied Petroleum Gas) cylinders able to adequately supply the branch. The system is far more flexible and widely used these days, and the equipment installation and ongoing costs save a king’s ransom in the process.

We recommended Flogas to supply the products as they are a leading provider of alternative energy solutions to domestic and commercial customers across the UK, and have been for more than 30 years. What’s more they have the largest nationwide LPG delivery network in the UK and the gas itself is competitively priced. They describe themselves as being such a reliable LPG gas supplier, “you’d never know you were off the grid”.
