Who We Are
A Family Business Built on Reputation
Prime Degrees Ltd is a family-run plumbing and heating company based in Bishop's Stortford, serving homeowners across Hertfordshire, Essex, and the surrounding areas. With over 20 years of hands-on industry experience behind us, we've built our reputation one job at a time — through quality workmanship, honest pricing, and genuine care for our customers.
Formerly trading as Glister UK, we rebranded to Prime Degrees Ltd to better reflect the premium standard of service we deliver — the same trusted team, the same commitment to quality, with a name that truly represents who we are.
We started because we saw too many homeowners being let down by tradespeople who didn't show up on time, didn't communicate clearly, and didn't take pride in their work. We set out to do things differently — and that commitment to doing things properly has never wavered.
Today, we're proud to be the trusted heating and plumbing partner for homeowners across the region. A significant part of our business comes from word-of-mouth recommendations — which we consider the highest compliment.

Quality Without Compromise
We use only premium materials and products. We don't cut corners — ever. If something isn't right, we fix it.
Honest & Transparent
Clear pricing, honest advice, and no surprises. We tell you exactly what we're going to do and what it will cost.
Respect for Your Home
We treat every home as if it were our own — protecting surfaces, cleaning up thoroughly, and leaving everything better than we found it.
Continuous Improvement
We invest in training, accreditations, and the latest technology to ensure we're always offering the best solutions.
