FAQ

Common questions from London homeowners

Straight answers on pricing, availability, coverage and the paperwork you might need.
How quickly can a plumber get to me in London?

For genuine emergencies — burst pipes, no water, active leaks — we dispatch the nearest available engineer straight away and confirm ETA on the callback. Planned jobs like cylinder swaps or bathroom work are booked into the next available slot with a firm arrival window.

Do you cover my postcode?

Yes — every London borough, from Barnet and Enfield in the north to Croydon and Bromley in the south. We work across all 32 boroughs, and each area has its own plumber-by-borough page with the property types and access notes we typically see there.

Is the price fixed before you start?

Always. We diagnose first, quote in writing, and only start work when you approve the price. No hourly runaway costs, no surprise invoices at the end.

Are you Gas Safe and G3 registered?

Yes. All heating and gas work is carried out by Gas Safe registered engineers. Unvented hot water cylinders are installed and serviced by G3-certified specialists. We also hold £5,000,000 public liability cover.

Can you provide reports for insurance or Thames Water?

Yes. Our leak detection team produces full written reports with photos, thermal images and tracer gas findings — accepted by insurers and Thames Water for leak notice responses.

Do you work with landlords and letting agents?

Regularly. We handle tenant callouts, provide clear paperwork and photos, coordinate access, and can quote before starting so managing agents can approve work quickly.

01

What we actually fix

Leaks, blocked drains, burst pipes, running or blocked toilets, dripping taps, leaking showers, boiler pressure faults, cold radiators, water heater problems and general bathroom plumbing make up most of our work. Some calls are urgent the moment they start; others have been getting slowly worse for weeks before someone finally rings up.

Homeowners, tenants, landlords, letting agents and small businesses all call for the same reasons: something is leaking, blocked, or not working, and they want it fixed properly without an open-ended bill at the end.

02

One number, whatever the problem

You do not need to work out the exact technical term for your fault before calling. Describe what you can see, give us your postcode, and we will match it to the right plumber and the right van stock.

We run a 24/7 line and quote the job before work starts, whether it is a five-minute tap repair or a hidden leak that needs tracing behind a wall.

03

If you already know what is wrong

Head straight to the service page that matches your problem for symptoms, prep steps and pricing detail specific to that job, or to your borough page for local coverage and property notes for your area.

If you are not sure which one fits, call 020 7101 0629 and describe it in plain language. We would rather ask a couple of extra questions than send the wrong plumber out.

04

London homes, flats and small businesses

A Victorian terrace, a converted flat with shared pipework, a new-build apartment behind a labelled service panel, and a shop with a staff washroom all bring the same kind of faults but different access questions. Telling us the property type when you call means the plumber turns up already knowing roughly what they are dealing with.

Tenants renting a flat, landlords managing several properties, and business owners trying to avoid closing for the day all get the same process: describe the fault, agree the price, then the work goes ahead.

05

Why we ask for a postcode before anything else

Your postcode tells us which plumber is closest, how quickly they can realistically get to you, and which of our local pages is relevant if you want more detail on plumbing in your area beforehand.

It also helps with parking, congestion charging and controlled zones, all of which affect how fast a plumber can actually reach a London address compared with the straight-line distance.

01

Getting a price agreed

Whatever brought you to this page, the pricing process stays the same: we look at the job, agree a fixed figure with you, and only then start work. If the scope changes once we are on site, for example a straightforward repair turning out to need a part replaced, we stop and talk to you again before carrying on.

That agreed-price step matters most when the person approving the cost is not the person on site, which is exactly the situation most landlords, agents and business owners are in.

Fixed price. Agreed first.
02

Before we arrive

If water is running, isolate it if you safely can, using the stopcock or nearest valve. Do not force anything that will not turn. Keep clear of any electrics near water, move belongings out of the way, and take a few photos once things are under control. If a drain is blocked, stop using the affected fixture rather than continuing to run water into it.

In flats and managed buildings, check whether building management controls any shared valves or riser access before we get there. If the property is rented, tell the landlord or agent early if their sign-off is needed before work can go ahead.

Isolate the water first
03

Recognising a genuine emergency

Treat it as urgent if water is actively escaping, a ceiling is dripping, electrics might be affected, a toilet cannot be used, a drain is backing up, a business cannot operate normally, or someone vulnerable has no hot water or heating. These situations need a same-day decision, because delay tends to make the damage or the disruption worse rather than better.

Contained issues can still go through the quote form rather than a phone call. If a leak has stopped, the water is isolated, or a fixture can simply be left unused for now, describe the problem and we will call you back to arrange a convenient time instead.

Same-day decision
04

Describing the problem clearly

Be specific about the room, the fixture and when it started. Say whether it is under a sink, behind a toilet, near a radiator, below a bath, around a shower tray, inside a kitchen unit or outside near a drain. Mention whether it started suddenly, only happens when a fixture is in use, or has been getting worse over a few days.

If there is water, say whether it is dripping, running, pooling or just showing up as a damp patch. If there is a blockage, say whether it is one fixture or several running slowly at once. If it is a boiler pressure problem, say how often it drops and whether any radiator valves or nearby pipework look damp.

"Water dripping from the light fitting below the bathroom."
05

Staying safe until we arrive

Do not lift flooring, remove panels or force valves you are not sure about. Avoid using the affected fixture if we have advised against it. Keep clear of any water near sockets, switches or appliances, and mention that when you call. If a ceiling is leaking, a container underneath is fine if it is safe to place one, but stay well away from any plaster that looks like it is sagging.

In flats and managed buildings, tell a neighbour or the building manager if water might be travelling between properties; shared plumbing can make the source hard to pin down, and an early heads-up avoids access problems later. If you run a business, keep staff and customers clear of wet floors and let us know if trading is affected.

Do not force what will not turn
06

What a fair quote actually looks like

A fair quote states the job clearly, covers labour and any parts needed, and does not change once work has started unless the scope genuinely changes. It should not leave you guessing what is and is not included. If a job might need a follow-up visit, for example to let plaster dry before a wall is made good, we say so at the quote stage rather than after the invoice lands.

Not every job costs the same, because not every property is the same. A ground-floor flat with an easy-to-reach stopcock is a different job to a boxed-in pipe run behind a bath panel in a top-floor conversion. What stays consistent is the order things happen in: we look, we quote, you agree, then work starts.

No hidden costs. No moving numbers.
07

Phone or quote form: which to use

Call 020 7101 0629 when the problem is active, spreading, or stopping you from using the property normally. Use the quote form when it is contained, when you would rather book a convenient time, or when a landlord, tenant or agent needs the details written down before approving the visit.

Either route gets you to the same place: we understand what is wrong, confirm when someone can come, and agree the price before work starts. Neither one commits you to anything until you have said yes to the quote.

Two routes, one answer
08

Getting ready for the visit

Before the plumber arrives, clear access to the affected area if it is safe to do so: empty the cupboard under a sink, move boxes away from a boiler, or unlock a meter cupboard if that is where access is needed. Make sure someone can answer a call from an unknown number around the appointment time, in case the plumber needs to confirm anything on the way.

If the property is rented, tell the landlord or agent as early as possible so their approval does not hold up the visit once a slot is booked. If you are in a managed block, check whether the building manager needs to be involved for lift access, concierge sign-off, or a shared riser cupboard.

Clear access saves time
09

Common reasons people get in touch

Most calls start with something visible or inconvenient: a ceiling stain after a shower upstairs, a blocked kitchen sink, a toilet that keeps refilling, a tap that will not shut off, a wet patch near a pipe, a boiler pressure drop, or a drain smell that keeps coming back. The sooner the symptom is described clearly, the easier it is to work out whether it needs urgent attention or a planned visit.

Some faults are not dramatic at first. A small drip can damage cabinets, flooring and plaster if it is left. A slow drain can become a full blockage within days. A pressure drop can point to a leak nowhere near the boiler itself. A short call is usually enough to turn a vague worry into a clear next step.

Drips, blockages, boilers, drains
10

Keeping the call short

You should not need to work through a long list of questions before speaking to someone. The basics get things moving: the type of problem, your name, phone number, postcode and a short explanation of what is happening. Anything more detailed can be sorted out once we are talking, rather than making you pick a technical term for a fault you have never had to name before.

Describing what you can actually see matters more than getting the terminology right. We would rather hear "water dripping from the light fitting below the bathroom" than have you guess at a diagnosis over the phone.

Yes. We look at the job, agree a fixed price with you, and only then start work.

Call 020 7101 0629 and describe what is happening. For anything urgent we will confirm the next available slot on the same call.

Can I mention more than one problem at once?
