The Winner’s Story…

Having won numerous awards, we wanted to share our 50-year story with you…
…To understand the winner’s story, we must first go back to where it all began…


Dennis used steam in his process to grow Chrysanthemums

Our founder

Dennis Baldwin became a well-established chrysanthemum and tomato grower. The entrepreneur ran his own successful business from the young age of 17.

Based on 3 sites around Yorkshire, Dennis used steam boilers to heat his 3 acres of glasshouses.

He came from a long line of engineers and with that inherent talent, he decided to design and install his own heating and boiler systems. Soon after, other horticultural businesses were recognising his flair for producing high-quality steam boilers and the demand for his products rose.

Dennis Baldwin & Sons was Byworth’s original name when the company was first established

Our founding

With two sons more interested in engineering than growing, Dennis took the brave decision (aged 42) to make a career change. He sold his successful horticultural company to finance a land investment to set up a factory. This was when Dennis Baldwin & Sons boiler manufacturers were first established; later to be known as Byworth Boilers. They supplied steam boilers, not only to growers but to other industries as well.
Dennis’ sons, Peter and Richard had joined the business, along with their mother, Dorothy.


The framework to the fitting shop extension can be seen to the left of the factory. The right of the building was erected in 1975.

Early growth and funding

After just two years in business, the company erected a portal frame building and purchased a mobile cabin to use as an office.

They were working all over the UK, installing glasshouse heating systems and boilers for sterilisation.

In 1972, the company purchased their first new Bedford Arctic and low loader trailer and erected a new 5-tonne overhead crane in their yard. Remarkably, the foundations for the crane tracks were dug by hand.

In ’73 they were buying boiler shells from a local Huddersfield business and finishing them in their workshop in Keighley. Later, they went on to buy a 2-pass dry back boiler design from long established company, Coltman’s, so Byworth began producing their own boiler shells in Keighley, West Yorkshire.

1974 saw the company buying their first semi-auto sub arc welding and ex-shipyard 12” rollers. They extended the workshop again and installed a 10-tonne crane among other machinery. The workforce was extended with several platers and coded welders.

In 1975, they fabricated and erected the first half of their boiler shop, but due to a period of political unrest in the UK, clients were cancelling their orders and Byworth Boilers were close to shutting down.

Finally, work began to pick up again in 1976 and the family business was back to their familiar ways of investing – with a new roof for the boilershop and a 20-tonne crane.

Their boiler range was beginning to increase.

In 1977 the business had initiated relationships in the Middle East, in particular, Libya, and so ‘Baldwin Overseas’ was created with overseas agents to look after export operations.

A further extension was added to the fitting shop in 1979, and a second 10-tonne crane added to their assets.

By 1986 consumer’s preference was moving from traditional coal-fired to oil and gas-fired boilers.

Continued investment, increased markets and extended product ranges

The beginning of the 80s saw Byworth’s first 3 pass wetback boilers designed and produced. All were coal-fired.

New equipment had been purchased and installed for producing the coal stokers and increasingly, more boilers were being exported.

In 1982 they acquired an extra 1-acre plot of land and in ‘83 the third extension to the fitting shop was completed.

From 1984-85 Byworth purchased their first new set 1” capacity plate rollers, allowing them to produce high-pressure boilers; along with a new 50-tonne capacity overhead crane and 2 more submerged arc welding machines with rotators and turntables.

By 1986, Byworth’s export markets included Egypt, China, Sri Lanka, Cyprus and Ireland, to name a few. The boiler range was continuing to expand due to a shift in market trend, where the consumer’s preference was moving from traditional coal-fired to oil and gas-fired boilers.

During 1987, they fabricated and erected a 150-foot extension to the boilershop to create extra floor space required for handling larger boilers.

Transforming the service offering

Peter Baldwin, who had developed his engineering skills from a young age, was beginning to show he followed his father’s entrepreneurial footsteps.

Peter transformed the family business to include a new element of their product and service offering; subsequently, delivering a new customer experience…

…In 1988, Peter had attended a site where its steam boiler had experienced an unexpected breakdown. This was where he had a sudden moment of inspiration. – Why couldn’t a boiler business offer their customers an immediate service whereby they could hire boilers? And that began the concept of installing a fully packaged boiler-house into an articulated trailer, complete with fuel tank and all other ancillaries – all ready to be mobilised and to be offered out to customers on a hire basis.

Now, if a customer had a sudden breakdown or required extra production capacity, there was a solution.

Later that year, the first ever mobile steam boiler was built and hired out to a Timber merchant. Byworth Boilers’ success had grown to establish a subsidiary company – known as Byworth Transportable Boiler Hire.

Within two years, its hire fleet had increased to an extended 10 boiler range.

Meanwhile, production at Byworth Boilers hit a staggering 100 boilers for the very first time.


Proud moment for the company – installation of four boilers at The Royal Albert Hall, London in 1992

The nineties

In 1991, the company was awarded the prestigious Royal Albert Hall contract for 4 new steam boilers.

A couple of years later, in 1993, Dennis Baldwin retired, and Peter took over as Managing Director.

Moving into the digital revolution, the first computer systems were installed in 1994.

Between 1995 and 1996, Thwaites yard was purchased, a result of the continuous expansion of the Hire fleet and extended range of new boilers.

A service division was established in the late 90’s with the new Hire Boiler service building erected in 1999.

In 2007, Ian Roberts was awarded the Derek Ezra Prize by the Combustion Engineering Association for his R&D work on behalf of Byworth.

Research and Development – Technological Advancement

Unfortunately, the beginning of this decade marked a very sad event in Byworth’s history; Dennis Baldwin passed away in 2002, aged 76.

We celebrate our founder and our business today in 2018, in Byworth’s 50th year in business.

Back to the story…

Byworth began to look at remote monitoring in 2002 (well ahead of its time) but knew the technology was not yet developed to the point they would want to bring it to the boiler market.

Instead, looking to increase production by 50%, they invested and erected a fitting shop at their Thwaites yard.

In 2003, Byworth purchased and installed their first CNC Plasma, installed a CNC drill and upgraded their plant rollers.

Peter’s son, Rob Baldwin, joined the company, aged 18, as an apprentice boilermaker.

In 2004, Helen Baldwin was appointed Finance and Marketing Director. Having already been with the company for 8 years, Helen had successfully implemented stock, costing, financial and management information systems giving Byworth a sound foundation for future growth.

Ground-breaking efficiency enhancements

During 2004, Byworth embarked on a very important venture with Leeds University. The partnership, which spanned over 2 years, was initiated when Byworth recognised that there had been limited progress in recent years with regard to improving the efficiency of shell boilers.

Fossil fuels, at that time, were seen to be a finite resource and their emissions to be a danger to health and the environment; so it was clear that these shortcomings should be addressed.

Shortly after, Byworth found Ian Roberts, who was to be their research and development engineer. A programme was devised to investigate the performance of shell and tube boilers, with the objective of improving boiler efficiency, therefore, reducing fuel consumption.

Subsequently, Ian went on to work for them as a consultant which enabled the R&D to continue and Ian is still an integral part of Byworth’s R&D today.

In 2007, Dr Ian Roberts was awarded the Derek Ezra Prize by the Combustion Engineering Association for his R&D work on behalf of Byworth.

The award was in recognition of his findings which included the discovery of X-ID tubes. These tubes existed in the American market and upon researching their efficiency-enhancing capabilities, Byworth and Ian were convinced of their value. In 2005, Byworth began to use this patented technology in our steam boilers. The boiler range that encompasses the X-ID tubes is the Yorkshireman2; we remain the only company in the UK that is authorised to use this technology.

Byworth’s other activities in this decade included the introduction of Boiler Operator Accreditation Scheme (BOAS) training and the opening of a second office in Stourbridge in 2005. Dr Ian Roberts frequently acts on behalf of Byworth as a training consultant for our range of boiler operator courses.


A testament to its unique value, Byworth’s intelligent control system, Unity, won a Queen’s Award for Enterprise in Innovation in 2016.

The last decade

In 2010, Byworth employed Rob Baldwin as Production Director. The company remained under the control of the Board which comprised of the Baldwin family.

At Byworth, we’ve always recognised that buying a boiler is a long-term investment, so it is important that it is as efficient as possible and extremely easy to maintain in order to maximise the investment and product lifecycle. Moving on through 50 years of innovation from those original Dennis Baldwin designs, Byworth has always pushed to be at the forefront of technology. So, we turned our attention to looking at improvements in boiler-house control and management to support our new and existing customers.

Our latest innovative equipment, Unity, is Byworth’s revolutionary boiler control system, which harnesses the power of digital technology to transform the industrial boiler industry. Unity began development in Spring 2013 and by Autumn 2013, the first system had been sold. A testament to its unique value, Unity won a Queen’s Award for Enterprise in Innovation in 2016.

A solution for any industry using process steam and hot water, Unity makes it easy to understand what is going on with their energy and operations. The system employs the Internet of Things (IoT) and advanced data analytics to systematically change boiler-related operations and services. Its value is in its capability to significantly reduce cost, improve product and service performance and provide better value to Byworth customers.

Encompassing a range of smart data, predictive tools, and engineering proficiency to obtain additional insight, the results will help customers reduce fuel usage, increase operational efficiency and significantly reduce any potential downtime. Delivering a step-change in boiler servicing, Unity helps improve response time, as well as enhancing onsite efficiency.

All of its attributes support a vision of providing efficient heat solutions with each partner.

In January 2016, Gavin Hindle joined the Board of Directors as Projects Director, Gavin had also worked for the company prior to his Directorship.

In 2017, plans were passed to double the size of the boiler shop and add another 50-tonne crane; a decision driven by the need for extra capacity due to increased product demand.

Where does the name Byworth come from?

The company, proud if its Northern base, began to use the name “Byworth Boilers” as its everyday trading name; “Byworth” being derived from the motto “by worth” in the Keighley Coat of Arms. This has a dual meaning – firstly, being judged by our ‘worth’ and secondly, being located by the River Worth which flows through the town.

Furthermore, part of the emblem shows a circle with blue wavy lines which represents water and refers to the situation of Keighley being in a well-watered valley; the streams of which flow through the town and used to supply the early factories with water-power before the steam engine came into general use.
