We always get asked this question and the simple answer is no. Your natural gas installer can upgrade your home to gas within one day. The team arrive in the morning, lay down protection mats where they are working and get the hoover out before they leave in the evening. The installers will remove your bulky oil tank and free up space in your hot press by removing your water tank. More space – no mess, no hassle, and no worries

Normally one day. Most of the installers on our gas safe registered list can complete a natural gas install within one working day. Of course every home is different so your installer will advise you on the works to be carried out and subsequent timeframes.

Every home is different so the total install cost will vary. However, we have calculated an average upgrade cost of around £2,200. That’s only £62 per month (over three years) with our 0% finance offer.

Our current offers are: £150 Cashback or 0% finance. This offer runs out on 14 th Dec ’18. T&C’s apply.

We often use a moling technique to connect your new meter box (on the side of your house) to our mains gas in the street. To do this we need to create small openings in the ground to connect the mains pipe to your new gas box. This procedure can normally be done very quickly, with minimal digging. Your energy advisor will fully explain this procedure before the works commence so you are at complete ease.
