A plumber is the number you want saved before you need it, because the moment you do need one there is usually water somewhere it should not be and very little time to shop around. A burst pipe at eleven at night is no moment to be reading reviews, so it pays to know in advance which of the city’s plumbers are the ones locals actually trust.
For this list we looked at the plumbers and plumbing-and-heating firms serving Portsmouth that carry a real body of customer feedback, and we went on the Google ratings and review counts rather than the vans and the leaflets. The firms were judged against one set of criteria, the reviews carrying the most, and we noted what each is strongest at, since the one-man local you want for a dripping tap is not always the firm you want for a full heating install.
A note on cost, because plumbing is charged by time rather than a fixed menu. A call-out with the first hour often lands somewhere around sixty to ninety pounds, with further time nearer forty to sixty an hour, and emergency or out-of-hours work costs more, while a boiler service runs roughly eighty to a hundred and twenty.
For anything involving gas or a boiler, always check the plumber is Gas Safe registered. Treat every figure as a guide, ask for a quote up front, and read the order as an editorial view rather than a recommendation. The list runs strongest first, starting at the top.
1. Prestige Plumbers
No plumber in the city carries a book like Prestige Plumbers, a 4.9 across more than five hundred reviews, which is in a different league from everyone else here on sheer weight of feedback. A near-perfect average held over a tally that size is the single strongest signal on this list, since it is simply not possible to keep five hundred customers that happy without doing the job right, time after time.
It operates as a full plumbing and heating outfit rather than a one-man band, covering the everyday repairs, bathrooms and installations as well as heating work, with emergency call-outs when something goes wrong. Reviewers return to prompt, tidy work and fair, clearly explained pricing, the two things that turn a one-off job into a saved number.
Charges follow the usual local pattern, a call-out and first hour in the sixty to ninety pound band with further time by the hour, quoted to the job. The only thing to weigh is that a firm this busy is best booked ahead for anything that is not an emergency.
Why it’s rated
- By far the deepest book here, a 4.9 from 500-plus reviews;
- a full plumbing and heating firm, not a sideline;
- praised for prompt, tidy work and clear pricing;
- emergency call-outs when something goes wrong.
Worth bearing in mind
- A larger outfit, so less of a single-person personal touch;
- in demand, so book ahead for non-urgent jobs.
The standout on the numbers, and the safe first call for almost any job.
2. M1K Plumbing & Heating Services
For a flawless score on a genuinely useful book, M1K Plumbing &, Heating is the one to beat, a perfect 5.0 from more than sixty reviews. That combination, an unbroken run of five-star ratings across a real spread of customers, marks it out as one of the most consistently praised firms in the city.
As the name says it pairs plumbing with heating, so it handles the boiler and radiator side as well as the taps and leaks, which makes it a strong single call when a job crosses from water into warmth. Reviewers rate the reliability and the sense of a job done properly rather than patched, and for heating or gas work that reassurance matters.
Pricing sits in the standard local range, quoted to the work, with the usual call-out and hourly shape. The smaller book than Prestige is the only real caveat, and as with any gas work it is worth confirming the Gas Safe registration when you book.
Why it’s rated
- A perfect 5.0 across more than 60 reviews;
- plumbing and heating under one roof;
- strong for boilers, radiators and gas work;
- praised for reliable, done-properly jobs.
Worth bearing in mind
- A smaller book than the biggest name here;
- confirm the Gas Safe registration for gas jobs.
The top pick when the job runs from plumbing into heating.
3. Pompey Plumb Ltd
Pompey Plumb wears its colours on its sleeve, a proudly local independent that holds a strong 4.8 from more than sixty reviews. It is the sort of genuine city plumber that builds its name one satisfied street at a time, and the rating reflects a steady record across the everyday jobs most households actually call about.
The appeal is exactly that local, independent feel, a plumber who knows the area and turns up to do the repairs, leaks and small installations that make up most of the work,without the overheads of a big firm. Reviewers tend to value the friendly, no-nonsense service and a fair price for an honest job.
Charges track the usual local shape, quoted to the work. The 4.8 sits just a fraction below the perfect-scoring names, more a reflection of the ordinary spread any busy plumber picks up than any real failing, so it remains a dependable local choice.
Why it’s rated
- A strong 4.8 from more than 60 reviews;
- a proudly local, independent Portsmouth plumber;
- solid on everyday repairs, leaks and small installs;
- a friendly, no-nonsense reputation.
Worth bearing in mind
- A rating just below the perfect-scoring firms;
- a smaller independent, so check availability for bigger jobs.
The pick for a genuine local independent for the everyday jobs.
4. Portsmouth Plumbers
Portsmouth Plumbers holds a perfect 5.0 from a smaller book of around thirty reviews, and every one of them points the same way, which for a plumber is about the best early sign there is. The simple, does-what-it-says name belies a firm that reviewers clearly rate for getting the job done.
It covers the general run of plumbing, from repairs and leaks to bathrooms and the urgent jobs that cannot wait, which makes it a sensible call for the common household problems. A perfect score on a growing book suggests a firm that is building its reputation the right way, and a smaller operation often brings a more personal service.
The caveat is simply the depth of the book, since there is less history to lean on than with the established names, so it is worth a look at the most recent reviews for the specific job. Pricing follows the local norm, quoted to the work.
Why it’s rated
- A perfect 5.0 from its reviewers;
- general plumbing, repairs and urgent jobs;
- a growing book built the right way;
- the personal feel of a smaller firm.
Worth bearing in mind
- A smaller review book than the leaders;
- check recent reviews for your particular job.
A strong, well-rated option for the common household jobs.
5. RMWS Plumbing & Heating
RMWS Plumbing &, Heating is another of the perfect-scoring firms, a 5.0 from around thirty reviews, covering both the plumbing and the heating side. The flawless rating across a decent early book marks it as a firm reviewers are genuinely pleased with, and the plumbing-and-heating remit gives it a useful breadth.
That breadth is the draw, since it can take on the boiler and radiator work as well as the standard plumbing, which saves lining up two different trades for a job that spans both. Reviewers point to tidy, well-finished work, the mark of a firm that cares how a job looks when it leaves.
As with the other smaller names the book is not yet as deep as the leaders, so it rewards a quick read of recent feedback, and the usual Gas Safe check applies for any gas work. Charges sit in the standard local range, quoted to the job.
Why it’s rated
- A perfect 5.0 across around 30 reviews;
- plumbing and heating in one firm;
- praised for tidy, well-finished work;
- handy when a job spans water and heating.
Worth bearing in mind
- A book still building towards the leaders’;
- confirm Gas Safe registration for gas jobs.
The one for tidy plumbing-and-heating work from a well-rated firm.
6. Dv Plumbing and Gas Services
Dv Plumbing and Gas Services holds a perfect 5.0 from around twenty-five reviews, and the name points to its real strength, the gas side of the trade alongside the plumbing. For anyone with a boiler or gas appliance to sort as well as the pipework, a firm that does both is a genuine convenience.
The gas-and-plumbing combination is the selling point, since gas work demands the right registration and a firm set up to handle it, and pairing that with general plumbing means one call for jobs that would otherwise need two trades.
Reviewers rate the professional, careful approach, which is exactly what you want around a gas supply. The review book is on the smaller side, so it is worth reading the recent ones, and as always with gas it is sensible to confirm the Gas Safe registration directly. Pricing follows the usual local shape, quoted to the work.
Why it’s rated
- A perfect 5.0 from around 25 reviews;
- gas work as well as general plumbing;
- a convenient single call for boiler and pipe jobs;
- a professional, careful approach.
Worth bearing in mind
- A smaller book, so read the recent reviews;
- confirm the Gas Safe registration for any gas work.
The pick when the job is as much gas and boiler as it is plumbing.
7. Honest Plumber Portsmouth
Rounding off the list, Honest Plumber Portsmouth puts its whole pitch in its name, and it backs it with a 4.9 from a smaller book of around seventeen reviews. Transparency is the thing people most want and least expect from a tradesperson, so a firm that leans into it and holds a near-perfect rating is worth a place here.
The appeal is straightforward, a plumber that trades on clear pricing and no surprises, which for the many people who have been stung by a vague bill is exactly the reassurance they are after. Reviewers value the upfront approach and the sense of being dealt with fairly.
The obvious caveat is the smallest review book on the list, so there is the least history to go on, and it is the sort of firm to get a clear written quote from at the outset, which fits its own promise anyway. Charges sit in the usual local range, quoted to the job.
Why it’s rated
- A 4.9 from its reviewers;
- a pitch built on clear, upfront pricing;
- valued for no surprises on the bill;
- a fair, transparent approach.
Worth bearing in mind
- The smallest review book on the list;
- get a clear written quote at the outset.
The option for anyone who wants pricing spelled out before the work starts.
Each plumber, by mark out of ten
The seven firms compared
| # | Plumber | Best for | Google rating | Typical charge | Score (out of 10) | % (out of 100) |

| 2 | M1K Plumbing & Heating | Plumbing + heating | 5.0 (66) | Quoted by the job | 9.2 | 92% |
| 3 | Pompey Plumb Ltd | Local everyday jobs | 4.8 (63) | Quoted by the job | 9.0 | 90% |
| 4 | Portsmouth Plumbers | General + urgent | 5.0 (33) | ~£60-90 call-out | 8.8 | 88% |
| 5 | RMWS Plumbing & Heating | Plumbing + heating | 5.0 (32) | Quoted by the job | 8.6 | 86% |
| 6 | Dv Plumbing and Gas Services | Gas and boilers | 5.0 (25) | Quoted by the job | 8.4 | 84% |

What the ratings quietly show
“Turned up when he said, fixed it, fair price,” reads one review, and that unglamorous reliability is what a near-perfect score across hundreds of jobs is really made of.
The first thing the numbers show is the gulf in review counts. Prestige Plumbers sits on more than five hundred, while most of the field counts theirs in the dozens. A perfect five from thirty customers is a fine sign, but a 4.9 from five hundred is a track record.
The second is how the field splits by specialism. The strongest names pair plumbing with heating or gas, which matters because so many household problems cross that line. Lower down, the perfect-scoring smaller firms are the ones to watch as their books fill, and for an everyday job almost any name here will serve you well.
How the marks were worked out
Every plumber picked up a mark out of ten. The reviews and a firm’s standing did the most, a little over a third, with the quality and reliability of the work a quarter, value and open pricing fifteen per cent, consistency another fifteen, and how quickly a firm responds the rest.
The figures are the public Google ratings logged in late October 2026, lined up against one another rather than drawn from a job we commissioned. Since plumbing is charged by time, we used the going local rates rather than a single invented price, broadly a call-out and first hour from around sixty to ninety pounds.
Ratings and charges both drift, and for any gas or boiler work the Gas Safe register is the check that matters most, so read this as a snapshot and get a quote before the work begins. A home throws up more than the odd leak, so our pick of the best car garages and a guide to moving across the city are worth a look when the next job lands.
