Gloucester Plumber and Heating Engineers

Looking for a Gloucester plumbing and heating firm that turns up when they say they will, quotes you a fixed price, and stands behind the work afterwards? That’s what we’ve been doing for over fifteen years.

Priority One Plumbing is based in Churchdown, so we’re rarely more than fifteen minutes from your front door. We’re Gas Safe registered, City & Guilds qualified, OFTEC accredited and Worcester Bosch accredited installers. Our engineers handle everything from a small leak to a full central heating system, across domestic and commercial properties.

Local Knowledge for Gloucester Properties

Gloucester's housing is a real mix and we work across all of it.

The Victorian and Edwardian terraces around Kingsholm, Barton and Tredworth need a different approach to the 1930s semis through Tuffley, Hempsted and Longlevens, or the newer estates at Quedgeley, Hunts Grove and Kingsway.

A few things we look out for in Gloucester properties specifically:

  • Conservation areas: Large parts of central Gloucester sit inside one. External work like an outdoor heat pump unit or a flue relocation sometimes needs planning consent and we’ll flag this early.
  • Older lead and galvanised supply pipes in pre-war terraces: this is worth knowing about because they affect water quality and pressure.
  • Back boilers in some older Cathedral and Kingsholm homes: we can decommission these properly and convert to a modern gas, oil or heat pump setup.
  • Gas pressure variations across the city: bigger combis sometimes need a gas supply upgrade in older terraces with 15mm runs.

Accreditations and What They Mean

Heating and gas work is regulated for good reason, and the wrong qualifications mean the wrong kind of cover when something goes wrong. What we hold:

  • Gas Safe registered. Required by law for any gas work in the UK. Every engineer carries an ID card you can check.
  • OFTEC accredited. Required for oil installations and servicing, which matters for off-grid Gloucestershire properties.
  • City & Guilds qualified. Plumbing and heating qualifications across the team.
  • Worcester Bosch accredited installer. Lets us register the extended manufacturer guarantee, up to twelve years on the Greenstar range.
  • Trust a Trader member. Independently verified reviews from Gloucester customers.
  • Microgeneration Certification Scheme (MSC). This ensures compliance with the UK quality standards for installers of small scale renewable technologies, such as heat pumps.

How we Quote and What we Charge

For small jobs (a leak, a tap, a service) we’ll usually give you a price over the phone and a straight time-and-materials quote when we arrive. For anything bigger we send an engineer out to survey the property properly. No phone-quote nonsense for boiler installs, heat pumps or bathroom refits, because the right price depends on what we actually see.

You’ll get a written quote with the parts, model numbers, scope, controls and warranty length all spelled out. If anything changes mid-job (it sometimes does on older properties), we’ll talk to you before doing the work, not after. No surprise extras when the invoice lands.

Why Gloucester Homeowners Choose Priority One Plumbing

We’re a local firm, not a national chain. The engineer who quotes the job is the engineer who fits it. You get: a proper survey before any non-trivial quote, a fixed price written down,engineers who arrive on time, lay dust sheets down, take boots off, and are polite. We service what we fit and we’ll remind you when annual servicing is due, which keeps the manufacturer guarantee valid.
