South West Heating Services has been part of the South West since 2019, serving homes from Bristol to Penzance.
Our Managing Director, Andrew Custer, started in the heating industry after leaving the Royal Navy. What began as a one-person operation has grown into a team of 13 regional engineers and 5 office staff, completing over 13,000 repairs annually.


We've been in business long enough to know what matters most: putting the customer first, every single time. That's the principle we've built our reputation on, and it's why our customers keep coming back.
In 2019, we refocused the business on what we do best. The results spoke for themselves — within 12 months, we were delivering more projects, serving more customers, and building stronger relationships than ever before.
Today, that same focus drives everything we do: a team that answers the phone, shows up on time, and gets the job done properly - no matter what.
In an industry where standards vary, we're the ones you can rely on.
We're a team of 13 regional engineers supported by 5 office staff who coordinate jobs, manage schedules, and ensure smooth service delivery.
Our high admin-to-engineer ratio isn't common in this industry, but it's how we maintain service levels that one-man bands can't match. When you call, someone answers. When we book a job, we show up.

Over 20 years, Andrew has grown the business and overcome challenges, always prioritising doing right by customers.
Andrew's reputation in the industry: "I don't take any nonsense. I fight my corner. But I always do what's morally right."


Domestic & General's TEQ Award is presented annually based purely on customer feedback across all their contractors nationwide.
We were runner-up in 2024 (and twice before under our previous company) recognition we're proud of, especially as a larger-volume contractor competing against smaller, owner-operated companies.
It's validation that doing things properly - answering calls, showing up, completing work to high standards - creates customers who recommend us.
This focused geographic approach means:
We're close enough to be responsive but large enough to answer the phone at 10pm on a Saturday.
