How Much Does a Plumber Cost in Portsmouth?

The Honest Answer: It Depends (But We'll Break It Down)

"How much will it cost?" — it's the first thing everyone wants to know, and rightly so. Nobody wants to call a plumber and get hit with a bill that makes their eyes water more than the leak did.

The truth is, plumbing costs vary depending on the job, the parts needed, how long it takes, and where you are. But we believe in transparency, so here's a straightforward breakdown of what you can expect to pay for common plumbing jobs in Portsmouth and the surrounding areas.

We're Scott and Fraser from Blimp Plumbing — we've been plumbing across Hampshire for years, and we've always been upfront about our pricing. No call-out fees for quotes, no hidden charges, and we always tell you the cost before we start.

How Plumbers Charge

Before we get into specific costs, it helps to understand how plumbers typically charge:

• Hourly rate — Most plumbers in Portsmouth charge between £40 – £70 per hour, depending on experience and qualifications. Gas Safe registered engineers (which you'll need for anything boiler or gas related) tend to be at the higher end.
• Day rate — For bigger jobs like bathroom fitting, many plumbers charge a day rate of £250 – £400 per day.
• Fixed price — For standard jobs like fitting a tap or replacing a toilet, many plumbers (us included) offer a fixed price so you know exactly what you're paying.

Common Plumbing Jobs and Costs

Dripping Taps

A dripping tap is usually a worn washer or cartridge. It's a quick fix.

• Tap repair: £60 – £120 (including parts)
• New tap installation: £80 – £150 (plus the cost of the tap itself)

Don't ignore a dripping tap — it wastes a surprising amount of water and can stain your sink or bath over time.

Toilet Repairs

Toilet problems range from a simple running cistern to a full replacement.

• Cistern mechanism replacement: £80 – £150
• Toilet replacement (supply and fit): £200 – £400
• Unblocking a toilet: £80 – £150

Leak Repairs

The cost of fixing a leak depends hugely on where it is and how accessible the pipework is.

• Accessible leak repair (e.g., under a sink): £80 – £200
• Hidden leak (behind a wall or under floor): £200 – £500+
• Emergency callout for a burst pipe: £150 – £350

Radiator Installation

Whether you're adding a radiator to a cold room or replacing an old one, here's what to budget:

• New radiator installation (including pipework): £200 – £400 per radiator
• Radiator replacement (existing pipework): £100 – £250
• Radiator valve replacement: £80 – £150
• System balancing (getting all radiators heating evenly): £150 – £250

Boiler Repairs and Servicing

Boiler work must be carried out by a Gas Safe registered engineer. Costs reflect the specialist qualification.

• Boiler repair: £100 – £400 depending on the fault
• Annual boiler service: £60 – £100
• New boiler installation: £1,800 – £3,500
• Boiler replacement (combi for combi swap): £1,800 – £2,500
• System conversion (e.g., conventional to combi): £2,500 – £4,000+

Central Heating

• Full central heating system installation: £3,000 – £5,500
• Powerflush (cleaning your heating system): £300 – £500
• Thermostatic radiator valves (TRVs), per radiator: £60 – £100

Bathroom Fitting

This is where costs vary the most because every bathroom is different.

• Full bathroom refit: £3,000 – £8,000+
• Shower installation: £300 – £800
• Bath replacement: £300 – £600 (plus the cost of the bath)
• Wet room conversion: £5,000 – £10,000+

The price depends on the size of the room, quality of fixtures, tiling requirements, and whether any structural work or re-plumbing is needed.

Gas Safety Certificates

• Gas safety check (landlord certificate): £60 – £90
• Gas safety check (multiple appliances): £70 – £120

Landlords in Portsmouth, Fareham, Havant, and across Hampshire are legally required to have an annual gas safety check on every gas appliance in their rental properties.

What Affects the Price?

Several factors influence how much you'll pay:

Complexity and Access

A leaking pipe under your kitchen sink is a quick, cheap fix. The same leak behind a tiled wall means we need to open up the wall, fix the pipe, and make good afterwards. More work, more cost.

Parts and Materials

We use quality parts because cheap components lead to callbacks. The cost of parts varies — a basic tap washer is pennies, a boiler PCB can be £200+. We always tell you the parts cost upfront.

Location

We're based in Portsmouth, so homes in Portsmouth, Gosport, and Fareham are our core patch. We also cover Havant, Waterlooville, and Chichester without issue.

How to Avoid Being Overcharged

A few tips to protect yourself:

• Get at least two quotes for any big job. We're confident in our pricing and happy for you to compare.
• Ask for a written quote, not just a verbal estimate. A quote is a fixed price; an estimate can go up.
• Check qualifications — For any gas work, your plumber must be Gas Safe registered. You can check registration numbers at gassaferegister.co.uk.
• Read reviews — Google reviews and local recommendations are your best friend. Ask neighbours in your area who they use.
• Be wary of very cheap quotes — If someone is significantly cheaper than everyone else, ask yourself why. Unqualified work can be dangerous and will cost more to put right.

Getting a Quote from Blimp Plumbing

We offer free, no-obligation quotes for all plumbing work across Portsmouth and Hampshire. Here's how it works:

1. Call or WhatsApp us with a description of the job
2. For small jobs, we can usually quote over the phone
3. For bigger jobs (bathrooms, heating systems, boiler installs), we'll arrange a free visit to assess the work
4. You get a written quote with a clear breakdown
5. No pressure — take your time to decide

We don't believe in pushy sales tactics. If you want to get other quotes too, go for it. We're confident our prices are fair for the quality of work we deliver.

Save Money on Plumbing

The cheapest plumbing job is the one you prevent. Don't ignore a dripping tap (£60 fix now vs a damaged cabinet later). Get your boiler serviced annually (£80 service vs £300+ breakdown). Insulate your pipes before winter. And book your gas safety check on time. Regular maintenance saves money every single time.
