Electricity is the one trade where cutting corners can quietly cost you your house or worse, so a good electrician is not a luxury but a safety net. The trouble is that the difference between a tidy, certificated job and a dangerous bodge is invisible until something goes wrong, which is exactly why the opinion of the people who have used a firm already is worth so much.
With that in mind we have gathered the electricians and electrical contractors working across Portsmouth who hold a real stack of customer reviews, and ranked them on their Google scores and the number of people behind those scores. One yardstick was applied to all of them, with the reviews pulling the most weight, and we have flagged what each firm does best, from the quick domestic call-out to the full rewire or the landlord safety certificate. One housekeeping note before the list, for anything notifiable, always check a firm is registered with a scheme such as NICEIC or NAPIT.
On money, electricians usually price by the job once they have seen it. A call-out with the first hour tends to sit around sixty to ninety pounds, an electrical safety report for a house often lands between a hundred and fifty and two hundred and fifty, and a new fuse board commonly runs from roughly four hundred and fifty upwards. Take the numbers as a steer, the ranking as our opinion rather than gospel, and the list in descending order with our favourite up first.
1. MBS Electrical Services
MBS Electrical Services takes top spot with a flawless 5.0 drawn from getting on for forty reviews, the strongest blend of score and volume in the city. Working out of the Eastern Avenue side of the city, it is the sort of firm whose name gets passed from one happy household to the next, which is how an electrician builds a book that good.
It handles the full domestic and small-commercial range, from extra sockets and lighting to consumer-unit changes, fault-finding and full rewires, with the safety certification that a job done right demands. “Turned up on time, clean job, fair price, and he explained everything as he went,” is the kind of review that keeps recurring. People single out the tidiness and the clear communication, the two things that separate a tradesperson you call back from one you do not. Pricing is quoted to the work, and the only thing to note is that a firm this well thought of is worth booking rather than leaving to the last minute.
Why it earns the call
- The best blend here, a 5.0 from nearly 40 reviews;
- a full domestic and small-commercial service;
- praised for tidy work and clear explanations;
- proper certification on notifiable jobs.
A point or two to check
- Popular, so book ahead for non-urgent work;
- confirm the scheme registration for notifiable jobs.
The standout on the numbers, and a safe first call for almost any job.
2. CPC Electrical and Mechanical
CPC Electrical and Mechanical, based towards London Road, holds a perfect 5.0 across more than thirty reviews, which places it right at the sharp end of the field. As the name hints, it pairs electrical work with the mechanical side, so it is a natural call where the two overlap.
That breadth is the draw, a contractor comfortable with the bigger or more involved job as well as the everyday domestic work, which suits a renovation or a commercial space as much as a house. Reviewers point to professionalism and reliability, a firm that does what it says when it says it. Charges are quoted to the job, in the usual local shape. The slightly smaller book than the very top name is the only caveat, and as ever it is worth confirming the registration for any notifiable work.
Why it earns the call
- A perfect 5.0 from more than 30 reviews;
- electrical and mechanical under one roof;
- at home with bigger and commercial jobs;
- praised for professionalism and reliability.
A point or two to check
- A smaller book than the leader;
- confirm scheme registration for notifiable work.
The pick where an electrical job runs into the mechanical.
3. Jon Taylor Electrical Services
From the Cosham side of the city, Jon Taylor Electrical Services carries a perfect 5.0 from close to thirty reviews. A named-tradesperson firm of this kind trades on a personal reputation, and an unbroken set of top ratings tells you that reputation is in good order.
The appeal is the reassurance of a single, accountable electrician who sees a job through, handling the usual run of domestic work, repairs, lighting and safety checks with evident care. Reviewers describe a trustworthy, no-fuss service and fair dealing, the sort of firm people are relieved to have found. Fees follow the local norm, quoted to the work. The book is a touch smaller than the biggest names, so a glance at the recent reviews is sensible, but the consistency is not in question.
Why it earns the call
- A perfect 5.0 from close to 30 reviews;
- a single, accountable named electrician;
- trusted for domestic work and safety checks;
- a no-fuss, fair reputation.
A point or two to check
- A smaller book than the top names;
- a solo firm, so check availability.
The choice for a trusted, one-name electrician on the Cosham side.
4. Mayo Electrical Contractors
Mayo Electrical Contractors holds a strong 4.9 from around thirty reviews, a well-established contractor with a broad base of satisfied customers across the north of the city. A near-perfect score on a book that size marks a firm with a genuine, settled track record.
Its strength is exactly that established, contractor feel, a firm set up for the fuller job, from rewires and board changes to larger installations, as well as the smaller domestic calls. Reviewers rate the competence and the sense of a job done properly and to standard. Pricing sits in the usual local range, quoted to the work. The 4.9 is a whisker below the perfect scorers, more the ordinary spread of a busy book than any real mark against it.
Why it earns the call
- A strong 4.9 from around 30 reviews;
- an established contractor for bigger jobs;
- good for rewires and board changes;
- praised for proper, to-standard work.
A point or two to check
- A fraction below the perfect scorers;
- confirm the quote for a larger installation.
The pick for a larger installation or a full rewire.
5. E-Lec Solutions
E-Lec Solutions, working from the Devonshire Avenue part of Southsea, holds a 4.9 from more than twenty-five reviews. It is a dependable all-round electrical firm that has built a steady, loyal following on the everyday work most homes and small businesses actually need.
The draw is its versatility, a firm as happy with a landlord safety certificate or an appliance test as with a lighting upgrade or a fault to chase down, which makes it a sensible single call for a mixed bag of jobs. Reviewers value the responsiveness and the straight talking. Charges are quoted to the work, in the usual range. As with the other mid-sized books it rewards a read of the recent reviews, but it is a reliable, versatile choice.
Why it earns the call
- A 4.9 from more than 25 reviews;
- versatile across domestic and small commercial;
- handy for safety certificates and testing;
- praised for responsiveness and straight talking.
A point or two to check
- A mid-sized book, so read the recent reviews;
- confirm scope for a larger project.
The versatile pick for a mixed bag of electrical jobs.
6. Coastal Electrical Installations
Coastal Electrical Installations, on the Cosham High Street side, holds a perfect 5.0 from around twenty reviews. The name points to its leaning, the installation side of the trade, and the flawless rating marks a firm its customers are genuinely pleased with.
The strength is that installation focus, a firm at home fitting out and wiring up rather than just patching, which suits a new kitchen, an extension or a lighting scheme. Reviewers point to neat, well-finished work and a professional approach from quote to completion. Fees follow the local pattern, quoted to the job. The review book is on the smaller side, so recent feedback is worth a look, but for installation work it is a strong, well-rated option.
Why it earns the call
- A perfect 5.0 from around 20 reviews;
- a clear leaning towards installation work;
- praised for neat, well-finished jobs;
- professional from quote to completion.
A point or two to check
- A smaller book than the leaders;
- best for installation rather than a quick fix.
The one for installation work and a tidy finish.
7. CDM Electrical and Fire
CDM Electrical and Fire holds a perfect 5.0 from around twenty reviews, and the name tells you its edge, the fire-safety side alongside the electrical work. For a landlord or a business that needs alarms and emergency systems as well as the wiring, a firm that does both is a real convenience.
The fire-and-electrical combination is the selling point, since fire-safety work demands its own know-how, and pairing it with general electrical means one call for jobs that would otherwise need two trades. Reviewers rate the thorough, safety-first approach, which is exactly what you want where alarms and escape lighting are concerned. Pricing is quoted to the work. The book is smaller than the biggest names, so recent reviews are worth a read, and it is worth confirming the relevant certification for fire systems.
Why it earns the call
- A perfect 5.0 from around 20 reviews;
- fire-safety work as well as electrical;
- one call for alarms and wiring together;
- a thorough, safety-first approach.
A point or two to check
- A smaller book, so read the recent reviews;
- confirm certification for fire systems.
The pick when the job is as much fire safety as electrical.
8. Blackmore Electrical Services
Rounding off the list, Blackmore Electrical Services carries a 4.7 from the deepest book here, more than forty reviews. It is a long-established name with the biggest body of feedback of any firm on the list, and a 4.7 held over that many jobs is a genuine, hard-won track record rather than a thin flash of early praise.
The appeal is that depth of experience, a firm that has handled a huge spread of work over the years and knows the trade inside out, from everyday domestic jobs to the more involved. Reviewers point to capability and a fair, no-nonsense service. The 4.7 sits a little below the perfect scorers, the natural result of the wide, varied book any busy long-runner builds up, rather than a warning sign. Fees follow the usual local range, quoted to the job.
Why it earns the call
- The deepest book here, a 4.7 from 40-plus reviews;
- a long-established, experienced name;
- a wide spread of domestic and larger work;
- a fair, no-nonsense reputation.
A point or two to check
- A rating a little below the perfect scorers;
- a busy book, so check availability.
The seasoned, high-volume choice with the deepest track record.

The marks, out of ten
What the ratings bring out
The headline is how tight the top is. Three firms share a flawless five, separated only by the depth of their books, and even the lowest score here is a creditable 4.7. In a trade where a bad electrician does not keep its reviews for long, that clustering says the city is genuinely well served.
Underneath, the field sorts itself by specialism more than by quality. One firm leans into fire safety, another into installation, a third into the mechanical side, and the one-name outfits trade on a personal reputation. The practical upshot is cheering, since the choice is less about dodging a dud than about picking the firm whose strength matches your job.
The thinking behind the order
Every firm was marked out of ten against the same short list of things. What customers say and how a firm is regarded counted for the most, roughly a third of the score. The standard and safety of the work came next, then the clarity and value of the pricing, the consistency behind the star rating, and finally how quickly a firm responds and covers the city.
All the scores rest on the public Google ratings and the number of reviews behind them, captured in late October 2026 and compared with one another rather than tested with a job of our own. Because electricians price by the work, we have quoted the going local rates rather than pretending a single fixed figure exists.
Both scores and prices change over time, so treat this as a picture of the field today and get a written quote before any work starts. For a notifiable job the scheme registration is the check that matters most. A house keeps every trade busy, so when the next job lands, our rated plumbers and car garages are each worth keeping to hand.
