We pulled 131 UK plumber adverts from Find a Job (the DWP's official UK board), filtered them to genuine plumbing roles, and counted what employers actually ask for. This is the third trades vertical in the series, after electricians and HGV drivers, and it has a clear surprise at the top.
The surprise: the UK plumber market is not primarily about installation. It is about maintenance, service and repairs. Most plumber CVs lead with the installs they have done, but the adverts are weighted heavily towards keeping existing systems running. If your CV leads with the wrong kind of work, you are answering a smaller question than the market is asking.
The headline: maintenance and service beat installation
Maintenance appears in 76% of adverts, service in 71%, repairs in 57%. Installation, the thing most plumber CVs lead with, appears in 54%. The reactive and ongoing work is the bigger market.
This does not mean installation experience is worthless. It means that if you have maintenance, service or repair experience, it should come first, because that is what most employers are screening for.
The top 10 things UK plumber employers actually ask for
Ranked by frequency across 131 real adverts.
Top keywords in UK plumber adverts
| Keyword | % of adverts |
|---|---|
| Maintenance | 76% |
| Service / servicing | 71% |
| Repairs | 57% |
| Installation | 54% |
| Health and safety | 51% |
| Heating | 50% |
| Commercial | 43% |
| Driving licence | 38% |
| Qualified | 37% |
| Domestic | 37% |
1. Maintenance, 76%
Three-quarters of adverts mention maintenance. If you have done planned preventative maintenance (PPM) or reactive maintenance, name which. “Reactive and planned maintenance across commercial sites” tells the recruiter more than “experienced plumber”.
2. Service and servicing, 71%
Seven in ten adverts mention service work. Boiler servicing, system servicing, scheduled service rounds. If you do service work, name the equipment and the cadence. Service experience is a major filter, especially for facilities and contract roles.
3. Repairs, 57%
Reactive repairs and breakdowns. If you have done callout and fault-response work, surface it. “First-time-fix on domestic breakdowns” is the kind of phrasing that lands, because employers care about whether you can diagnose and fix on the first visit.
4. Installation, 54%
Still more than half of adverts, so it matters, just less than most plumber CVs assume. Name the kind of installation. First fix and second fix, bathroom installs, commercial pipework. Be specific about the setting.
5. Health and safety, 51%
Use the exact wording. “Health and safety” is a direct match in half of adverts. If you hold a CSCS card, mention it. If you have done any required training (working at height, asbestos awareness, manual handling), name it.
6. Heating, 50%
Half of plumber adverts involve heating work. If you do heating as well as plumbing, say so explicitly, and if you hold Gas Safe or ACS, that belongs in line 1 of your summary. If you are water-only, be clear about your scope so the employer knows what they are getting.
7. Commercial, 43%
Commercial work (offices, retail, healthcare estates, schools) is the largest single setting type, edging out domestic. If you have commercial or facilities experience, lead with the setting. “NHS estates”, “commercial facilities maintenance”, “school contract work”. Specific beats generic.
8. Driving licence, 38%
More than a third of adverts require a UK driving licence because most service and maintenance roles involve travelling between jobs. State it plainly. If you have your own van or a clean licence, mention that too.
9. Qualified, 37%
A general term but a real screen. Adverts using “qualified plumber” are filtering out improvers and mates. If you are qualified (NVQ Level 2 or 3 plus experience), put it in the first line so the recruiter does not have to dig.
10. Domestic, 37%
Domestic work is roughly level with the qualified screen. If your experience is domestic, target the domestic and service roles directly and name the setting. Do not apply for commercial-only roles with a purely domestic CV unless you are explicit about wanting to cross over.
The signals that quietly separate you from the pile
Six signals that do not make the top 10 but appear often enough to matter where they apply.
- NVQ Level 2, 24%. More common as a stated requirement than Level 3. If you hold it, name it. Many maintenance roles accept Level 2 plus experience.
- Legionella awareness, 23%. A real differentiator in commercial, facilities and social housing roles. If you have the certificate or have done risk assessment work, surface it.
- NVQ Level 3, 19%. The full qualification. Name the number if you hold it, not just “qualified”.
- Social housing, 18%. A large and stable employer segment. If you have done void work or tenanted repairs, name it directly.
- Fault finding, 18%. Strong signal for service and breakdown roles. Name the systems you diagnose on.
- Unvented G3, 11%. Niche but high-value. If you hold the unvented hot water (G3) qualification, it opens roles that general plumbing experience cannot.
What plumber adverts barely mention
- Soft skills. Communication appears in 34%, reliability in 13%. Worth a passing mention but not worth leading with. The trade competency is the screen.
- Bathroom fitting specifically. Only 11%. A common CV lead that does not match how often employers actually ask for it. Fold it into installation experience rather than headlining it.
- Drainage. 12%. Useful if you do it, but a specialism rather than a core screen for general plumbing roles.
The UK plumber market runs on keeping things working, not just fitting new things. Lead with maintenance, service and repairs. Name your qualifications by number. Put the driving licence in plain sight. The installs come after, not before.
Before and after
A qualified plumber with commercial maintenance experience had this summary.
“Hard-working and reliable plumber with experience in bathroom installations and general plumbing. Strong attention to detail and a great team player. Looking for a new role with a good company.”
Tailored against a real advert using the patterns from 131 real adverts.
“Qualified plumber, NVQ Level 3, Legionella awareness, full UK driving licence. 7 years across commercial maintenance, service and reactive repairs on healthcare estates and social housing. First-time-fix focus on breakdowns. Own van and tools.”
Same plumber, same experience. The vague version led with bathroom installs (54% of the market) and buried the maintenance and service experience the other 76% and 71% of adverts actually want. The tailored version puts the in-demand work first and names every screening signal in two lines.
Frequently asked
Should I lead my plumber CV with installation or maintenance experience?+
Lead with maintenance and service if you have it. We read 131 UK plumber adverts and maintenance appears in 76%, service in 71%, and repairs in 57%. Installation only appears in 54%. The market is weighted towards maintenance and service work, so a CV that leads with "experienced in bathroom installations" is answering a smaller question than the market is asking. Name your maintenance, service and repair experience first.
Do I need NVQ Level 3 to be a plumber, or is Level 2 enough?+
It depends on the role. NVQ Level 2 appears in 24% of UK plumber adverts and Level 3 in 19%, so Level 2 opens more doors than you might expect. Many maintenance and service roles accept Level 2 plus experience. If you hold Level 3 it is worth naming because it signals the full qualification, but do not assume Level 2 locks you out. Put whichever you hold on line 1 of your summary.
How important is a driving licence on a plumber CV?+
Important. A full UK driving licence appears in 38% of UK plumber adverts as a requirement, because most maintenance, service and callout roles involve travelling between jobs. If you hold one, state it plainly in your summary. If you have a company van or your own van, mention that too. It removes a question the recruiter would otherwise have to ask.
Should I mention Gas Safe or heating qualifications if I am a water-only plumber?+
Only mention Gas Safe if you hold it, and never imply it if you do not. Heating appears in 50% of plumber adverts and many combine plumbing with heating work. If you are water-only, that is fine, but be explicit so the employer knows your scope. If you do hold Gas Safe or ACS qualifications, those are high-value and belong in line 1, because they widen the roles you can take significantly.
What should a plumber CV say about Legionella and water regulations?+
Name them if you have the training. Legionella awareness appears in 23% of UK plumber adverts, particularly in commercial, facilities and social housing roles. WRAS and water regulations knowledge is also valued. If you have done Legionella risk assessment work or hold the awareness certificate, surface it. It is a differentiator in maintenance and facilities roles where water hygiene compliance matters.
Is commercial or domestic plumbing experience more in demand?+
Commercial edges it. Commercial appears in 43% of UK plumber adverts versus domestic in 37%, with a chunk of facilities and social housing work on top. If you have commercial or facilities maintenance experience, name the setting types (offices, healthcare estates, schools, social housing). If you are domestic, target the domestic and service roles directly. Either way, name the setting because employers screen for the kind of environment you are used to.
The next time you write your plumber CV
Read the advert's first three lines. If it says maintenance, service or repairs, your summary should say the same words back before it mentions a single installation. The qualification and driving licence go on line 1. Specific settings beat generic claims every time.
