Gas, boiler or heating? The HSE states that anyone employed to work on gas appliances in domestic premises must be a Gas Safe registered engineer, competent in that area of work — so a boiler, gas appliance or gas pipework needs the boiler and central-heating pages, not a general plumber.1

Which job do you actually have?
“General plumbing” covers the everyday jobs that don’t have a specialist name — but a lot of problems people land here with do, and you’ll get a faster, better-matched plumber by going to the right page. A quick sort:
- The toilet runs, won’t flush, or leaks — that’s a mechanism job: Toilet Repairs.
- A tap drips, is stiff, or you want a new one fitted — Tap Repair & Installation.
- A sink, bath or drain won’t clear — Blocked Drains.
- There’s damp, a stain or a water meter ticking with no visible cause — Leak Detection.
- A pipe has burst or frozen — Burst Pipes.
- It’s urgent, or out of hours — Emergency Plumber.
- It’s the boiler, a gas appliance or gas pipework — that must be a Gas Safe registered engineer (see the boiler and central-heating pages). A radiator that won’t heat may just be a general plumbing or heating job — bleeding, balancing, a stuck valve or the pump — unless the work involves the gas boiler itself.
If none of those quite fit — or you genuinely aren’t sure — this is the right page. The verified plumbers listed handle the general jobs below, and a good one will tell you honestly if your problem is really one of the specialist categories above.
The small jobs and odd jobs
These are the bread-and-butter general jobs — individually small, but worth doing properly:
- Overflow pipes. A pipe dripping outside usually means a float or valve inside a tank or cistern isn’t shutting off. Cheap to fix, but worth not ignoring — it wastes water and, in winter, a constant dribble can ice up.
- Ballvalves and float valves. The valve that controls the water level in a cold tank or cistern; a worn or stuck one causes overflows or slow refills.
- Isolation (service) valves. The little in-line valves that let a single tap, toilet or appliance be turned off without draining the whole house. Fitting them makes every future repair quicker — and the Water Regulations guidance expects a servicing valve on the inlets to cisterns, float-operated valves and appliances such as washing machines and dishwashers, to allow for maintenance.2
- Stopcocks. The main shut-off for the property. A seized or weeping stopcock is a common find, especially on older supplies. Before replacing one, a plumber will usually check whether there’s an external stop tap that works, whether the internal stopcock fully closes, and what the pipework is made of — lead, copper or plastic — since that changes how it’s connected. It’s worth knowing yours works before an emergency: our find your stop tap guide shows you where to look.
- Radiator bleeding and balancing. Cold spots at the top of radiators usually just need bleeding; uneven heating across the house may need balancing. These are general-plumbing jobs — a plumber can do “wet” work like radiators and pipework — but the boiler itself, the final connection to it, and anything on the gas side must be a Gas Safe registered engineer.1
- Appliance plumbing. Connecting a washing machine or dishwasher, fitting the right supply valve and — just as important — checking the waste route, including the standpipe and trap height, so the appliance doesn’t siphon or leak.
- Waste traps, U-bends and water hammer. Reseating a leaking trap, or tracing banging pipes (water hammer) to loose pipe clips, a quick-closing appliance valve or high pressure, and fitting an arrestor where needed.
Outside taps and the backflow rule
Fitting a garden or outside tap looks like a simple job, and it’s a common general-plumbing request — but there’s a regulatory wrinkle worth knowing, and it’s a job where compliant installation matters. According to WaterSafe, the UK’s register of approved plumbers, the Water Supply (Water Fittings) Regulations require an outside tap to have a double check valve to prevent backflow — stopping water (and any bacteria) being siphoned back from a hose into your drinking-water supply, and WaterSafe advises using an approved plumber if you’re unsure.3
In practice, the double check valve is fitted on the supply pipe inside the warm part of the house (it can be damaged by frost if left outside), and a separate isolation valve lets you shut the outside tap off and drain it down for winter. A verified plumber fits it compliantly and, on Havering’s hard water, will use good-quality valves that won’t seize up — which matters, because a backflow device that’s furred solid isn’t protecting anything.
Hard water and everyday plumbing in Havering
Many Havering homes are on a hard-water supply, including Essex & Suffolk Water’s hard-water area, where the company confirms hardness leaves limescale.4 For general plumbing, that shows up in small but predictable ways: stopcocks and isolation valves seize if they’re never turned, ballvalves and float valves fur up and stop sealing, and valves and washers wear faster than in soft-water areas. It’s a good reason to have a plumber free off and check your stopcock and main valves periodically — and, when fitting anything new, to choose fittings that stand up to scale.
When parts are renewed, they should meet the rules. Under the Water Supply (Water Fittings) Regulations 1999, no material likely to cause contamination may be used in the repair or replacement of a fitting that carries water for domestic use.5 More broadly, Regulation 4 requires water fittings to be of an appropriate quality and standard; in practice that means Regulation 4 compliant fittings, with WRAS (or equivalent, such as KIWA or NSF) approval used as evidence of compliance.6
If you rent, or it’s a flat: keeping the water supply, pipework and sanitary fittings in working order is part of a landlord’s repairing obligations. Under Section 11 of the Landlord and Tenant Act 1985, a landlord must keep in repair and proper working order the installations for the supply of water and for sanitation.7 So report a general plumbing fault to your landlord or letting agent rather than booking privately. Our landlord plumbing compliance checklist covers the wider duties.
Find a verified plumber by district
Havering is an outer-London suburban borough, with many suburban houses alongside flats, maisonettes and newer developments — and the general plumbing here reflects the local stock and its hard-water supply. Here’s the picture by area.
Romford (RM1, RM2, RM7) — town-centre flats above shops and a wide spread of suburban housing in Gidea Park, Rise Park and Mawneys. In flats and maisonettes, small jobs like a dripping overflow or a leaking appliance connection can affect the unit below — and where there’s a shared stopcock or riser, the managing agent may need to give access before an isolation valve or appliance connection can be altered.
Hornchurch & Elm Park (RM11, RM12) — many 1930s inter-war semis, bungalows and detached houses, often with older pipework where stopcocks and isolation valves have seized through age and scale. The internal stopcock is sometimes boxed in or hidden behind kitchen units, so freeing off or renewing it is a common — if occasionally fiddly — general job here.
Upminster & Cranham (RM14) — larger suburban homes with more bathrooms, gardens and outside taps, and so more of the small fittings (valves, overflows, garden taps) that make up general plumbing. Extended kitchens can also mean longer or awkward appliance and outside-tap pipe runs.
Rainham, South Hornchurch & Beam Park (RM13) — older mixed stock beside new-build Beam Park homes. New-builds often have modern isolation valves and built-in backflow protection on outside taps, though shut-offs may sit behind an access panel or in a service cupboard; older stock may need valves retrofitted to bring it up to a serviceable standard.
Harold Hill, Harold Wood & Collier Row (RM3, RM5) — includes post-war estate housing with family homes, maisonettes and flats, plus mid-century houses and 1930s Collier Row stock. In maisonettes and blocks, a small leak or overflow is worth fixing promptly because of the neighbouring and lower units.
Gidea Park, Emerson Park & the rural edge (RM2, RM4) — larger detached houses with gardens, multiple outside taps and longer pipe runs, sometimes complicated by extensions that have moved the kitchen or sink. Out toward Havering-atte-Bower, Noak Hill, Corbets Tey and North Ockendon, rural-edge properties can have older or extended plumbing, so a verified local plumber will check what’s actually there before quoting.
If you’re near the Romford / Barking & Dagenham boundary at Rush Green, confirm your postcode is RM and within Havering before booking.

| Standard call-out / first hour | £60–£120 |
| Fix an overflow / ballvalve | £70–£140 |
| Fit an isolation or service valve | £70–£130 |

Havering is outside the central London Congestion Charge zone, but like every Greater London borough it sits inside the London-wide Ultra Low Emission Zone (ULEZ), which the TfL ULEZ scheme operates across all London boroughs (excluding the M25 itself). A non-compliant vehicle may incur the daily charge, so it’s reasonable to ask whether any emissions-zone charge is included in a quote.8
When you contact a plumber from this directory, you can ask about availability, whether there’s a call-out charge or a minimum, whether several small jobs can be done in one visit, and whether parts are included — you’re not obliged to proceed until you’ve agreed the next step. VerifiedPlumbers is a directory that connects you with verified plumbers; it doesn’t carry out the work itself.
Frequently asked questions
The everyday jobs that don’t have a specialist name — overflow pipes, ballvalves, isolation valves, stopcocks, fitting an outside tap, bleeding radiators, plumbing in a washing machine, reseating a leaking waste trap, and general pipework.
If your problem is a specific one — a running toilet, a dripping tap, a blocked drain, a hidden leak, a burst pipe, or anything on the boiler — there’s a dedicated page for it, which will match you with a better-suited plumber.
A general plumber is usually right for small repairs, valves, stopcocks, appliance connections, waste traps and outside taps.
If the problem is a blocked drain, hidden leak, burst pipe, faulty toilet or dripping tap — or anything urgent — use the specialist Havering page for it, so you’re matched with a plumber set up for that work.
Anything on a boiler or gas appliance must be done by a Gas Safe registered engineer, as the HSE requires for gas work in the home.
Usually yes, and it’s often the most economical way to handle a list of minor jobs — a plumber can tackle the overflow, the dripping outside tap and the seized isolation valve in a single call-out rather than separate visits.
It’s worth listing everything when you make contact so the plumber can allow enough time.
It’s strongly advisable.
An outside tap needs a double check valve to prevent contaminated water being drawn back into your drinking supply, and that’s best fitted compliantly inside the property where it won’t freeze.
A verified plumber fits it to the regulations and uses approved, scale-resistant valves.
It’s worth sorting.
A seized stopcock — common on Havering’s hard water — means you can’t isolate the water quickly in an emergency.
A plumber can free it off or replace it, and it’s a small job that saves a lot of grief if a pipe ever bursts.
If you rent, general plumbing repairs to the water supply and sanitary fittings are normally the landlord’s responsibility under Section 11 of the Landlord and Tenant Act 1985, so report them to your landlord or agent.
In a flat, shared pipework, stacks or a shared stopcock may involve the freeholder or managing agent — worth confirming before booking privately.
