When you say Swindon, you usually think about industrial estates and industrial revolution but there is much more than that to Swindon. Yes, it emerged as one of the few Industrial Revolution powerhouses of the South West England during the 1840s mainly thanks to Isambard Kingdom Brunel who set up a railway company in the town. Other industries followed and this is how it acquired its industrial reputation.

Soon after the industrial boom, an interesting social experiment took place in Swindon that formed the basis of the NHS as we know it today – employees of the railway works were required to make a small contribution entitling them and their families to unlimited healthcare. This scheme was really successful and very few industrial areas up North had an alternative.

Historically, development of this area of Wiltshire was based on barter trade making Swindon one of the most important market towns in the South. However, there’s much more to Swindon than just the industry or markets.

The convenient transport links has made sure the town is diverse both in its business and cultural opportunities. If you look at it on the map it feels like it’s in the middle of nowhere, however, it’s only 35 miles from Bristol and just 70 miles from London. Part of the vision is to improve the rail links to the Capital and cut down travel times to just 45 minutes. This convenience has meant that the area has developed and grown significantly during the last century. It grew from just a couple of tens of thousands people at the turn of the 19/20th century to the prediction of breaking the barrier of 200,000 people by 2025.

Us as boiler installers are mainly interested in the town’s expansion plans, new builds and redevelopment projects. The situation is really looking on the up as Swindon enjoys low unemployment rates. There is around 110,000 jobs in Swindon – a number that is predicted to rise to 116,000 by 2020 so the area is bracing itself for an exponential growth.

The town is mainly expanding towards the North with new suburbs appearing and growing constantly. Back in 2016 there were 95,000 households in Swindon. Now, the number has risen to almost 100,000 households. That’s 5,000 new homes built in a space of 3 years. All these properties have had a need for a new boiler and that’s not including the new generation combi boilers replaced in existing properties to meet the town’s green credential vision.

There is more to come as the Council is looking to develop various brownfield sites that it owns in and around Swindon – such as Oakfield and Wichelstowe. More than 3,000 new homes have been planned to be built in those areas.


Although Swindon is an industrial place, at the same time it is working hard on its green vision. Part of its eco reputation is down to the world-famous Self Build centre that is a landmark building and a hub for everything related to self-build and eco architecture. Majority of the people going down the self-build route, will probably choose an alternative to gas boiler. Such as heat pump, biomass burner or even solar cells.

Although, the average 1560 hours of sunshine it gets per year is not remarkable, Swindon is still better positioned than most places towards the North, so it should be good enough to make sense installing solar cells. Even though it may not provide the entire amount of energy required to power your home in Swindon. Although green heating technology has enjoyed a real boost in efficiency, we find that many self-build homeowners choose gas boiler installation in Swindon as a backup plan so they have a reliable heat source if the green tech fails to provide enough energy.

This is a very good approach as it still keeps you on the grid with an option to save a lot of money on your gas bills. Boiler installers in Wiltshire predict that the number of households owning more than one heating source will increase during the next few years. This is good news for companies like Glow Green as we know that there is going to be plenty of new boiler installations required in the area.
