About Us


Sham Singh


Our founder, Sham Singh, set up the company in 2007 after seven years as a Gas Engineer. From humble beginnings, we’ve grown organically and remain a family business. Today, our tradespeople have over 60 years of combined experience. Our expertise and technical know-how mean you can rely on us to get things right.

At CRS Gas & Heating, we’ve been loyally serving Leicester’s Stoneygate, Knighton and Clarendon Park communities for over a decade. We specialise in servicing, repairing and installing domestic gas appliances. We also provide Smart home installations.

We’re proud to be different.

When you commission us to work on your project, you don’t just hire a plumber or gas engineer. You tap into a network of respected academics, industry professionals and specialist tradespeople.

So, shall we get to know each other? Let us introduce ourselves and tell you a little more about what makes us #different


We work and recruit locally. Many of our customers have been with us for years. Most of our new business comes from existing customers recommending us to people they know. Quite simply, we can’t afford to get things wrong. That’s why our attention to detail is second to none and why we go out of our way to make sure you’re entirely happy with our work. Meanwhile, through our mentorship programme, we’re giving back to the community, guiding and inspiring Leicester’s next generation of trade professionals.


Our academic partnerships mean that you benefit from the latest research and technical innovations. Our team members are constantly looking into new ways to do things, staying ahead to ensure you get the best possible service. We use PartsArena, the industry leading web-based parts identification tool. It is the leading source of approved boiler manuals and parts data for the UK. We can see live stock availability, meaning we can get your boiler fixed fast.


We invest in secure web-based software that will keep you up-to-date with the progress of your project. Your details are securely kept online, so you don’t have to worry about losing your certificates, quotes or invoices. Paying is easy too – just follow the link on your invoice to pay securely online and get a receipt straight away. And if you need to get in touch with us directly, you can contact one our friendly team by phone, text or email.
