What do you need?
Choose the job. Each one says what to send, and whether to call.
A leak or burst
If water is still running, call with the postcode. Otherwise say where it appears and send a photograph of the path.
Call 020 7101 3168A tap, toilet or waste
Photograph the fitting and any isolation valve, and say whether you already have the replacement.
Send this in a briefBathroom or kitchen pipework
Mark the positions you want. A whole new room is quoted as a bathroom or kitchen renovation, with the plumbing inside that scope.
Send this in a briefA radiator or heating pipe
Say whether one radiator or the system is affected. Gas appliances are assigned separately to a Gas Safe-registered engineer.
Send this in a briefA shared stack in a block
Include the floor, porter hours and whether the pipe is private or communal.
Send this in a brief
Start with the plumbing outcome, not a generic call-out
A plumbing brief can be a visible leak, a failed tap or valve, a waste problem, a sanitaryware change, a radiator connection or first-fix work for a bathroom. Those are different diagnostic and pricing paths. State what is happening now, where the water appears and what changed beforehand. If the problem is uncontrolled, use the emergency plumber route and call first; planned plumbing requests stay in this hub.
Leak source versus the place where water appears
Water can travel along pipework, joists, ceilings and service boxing before it becomes visible. A stain below a bathroom does not by itself identify the failed component. Send photographs of the affected fitting, the wider room, the ceiling or wall below and any meter or pressure change you noticed. The next step may be a targeted inspection or opening-up proposal rather than an immediate promise to replace the nearest visible fitting.
Taps, toilets and sanitaryware replacements
For a tap, toilet, basin or shower fitting, include the existing model where known, connection photographs, dimensions and the replacement item if already selected. Concealed cisterns, wall-mounted fittings and imported brassware can change access and parts availability. The written scope should say whether isolation valves, waste connections, sealant, boxing and making good are included. Client-supplied products remain subject to compatibility checks before installation is confirmed.
Bathroom and kitchen first-fix plumbing
First fix is coordinated with the room layout, floor and wall build-up, waterproofing, joinery and final fittings. Moving a soil connection is not equivalent to moving a tap. Drawings or marked-up photographs should show appliance positions, waste falls, hot and cold routes, valves and any underfloor constraints. A full room redesign belongs in the bathroom or kitchen renovation route when plumbing is only one part of a larger managed package.
Radiators, heating pipework and the gas boundary
Radiator valves, pipe alterations and water-side heating work can begin as a plumbing brief, but appliance combustion and gas work require a Gas Safe-registered engineer assigned for that accepted scope. Tell us the boiler or heat-source type, system pressure symptoms, radiator locations and whether the whole system or one emitter is affected. This keeps a plumbing attendance from being mistaken for a gas or boiler appointment.
Parts, diagnosis and a clear plumbing price basis
A straightforward replacement may be quoted when the component, access and connections are clear. Concealed leaks, intermittent faults and seized fittings often need diagnosis before the repair scope is reliable. The price basis should distinguish attendance or investigation, labour, parts, access or opening-up, reinstatement and follow-on work. We do not advertise one postcode rate that pretends every leak or bathroom connection carries the same risk.
What a completed plumbing record should contain
For accepted work, the message thread and quote preserve the reported problem, agreed repair, replaced parts and any remaining observation or follow-on recommendation. Photographs are useful where work becomes concealed. If the attendance only makes an installation safe or stops a leak, the permanent repair remains a separate stated next step. Payment follows the written scope rather than an amount invented from the enquiry form.

People Also Ask About Plumber
Does every home have to have a stopcock?▼
Yes. In England and Wales, paragraph 10 of Schedule 2 to the Water Supply (Water Fittings) Regulations 1999 requires every supply pipe or distributing pipe providing water to separate premises to be fitted with a stopvalve, conveniently located so the supply can be shut off without shutting off any other premises. Where one pipe supplies two or more premises in common, each occupier must have access to a stopvalve.
Source: Schedule 2, paragraph 10, Water Supply (Water Fittings) Regulations 1999, legislation.gov.uk
Does installing an unvented hot water cylinder need building regulations approval?▼
Yes, in England. Approved Document G states that installing an unvented hot water system is notifiable building work that must be notified to the building control body before work commences. Advance notification is not needed where the installer is registered with a competent person scheme for unvented hot water systems, because that installer self-certifies compliance and a building regulations certificate is then issued to the building owner.
How much water is a new build home allowed to use per person?▼
125 litres per person per day, in England. Regulation 36 of the Building Regulations 2010 caps the potential consumption of wholesome water by people occupying a new dwelling at that figure, measured using a methodology approved by the Secretary of State. A tighter optional requirement of 110 litres per person per day applies where planning permission specifies it and makes it a condition.
Source: Approved Document G, requirement G2 and regulation 36, GOV.UK
Is there a legal standard for how plumbing must be installed in a UK home?▼
Yes. In England and Wales, regulation 4 of the Water Supply (Water Fittings) Regulations 1999 requires every water fitting to be of an appropriate quality and standard, suitable for the circumstances in which it is used, and to be installed, connected, altered, repaired or disconnected in a workmanlike manner. Fittings must also comply with the applicable requirements of Schedule 2 to those Regulations.
Source: Regulation 4, Water Supply (Water Fittings) Regulations 1999, legislation.gov.uk
What is the maximum hot water temperature allowed at a bath tap?▼
48°C, in new and converted dwellings in England. Requirement G3(4) of Schedule 1 to the Building Regulations 2010 requires the hot water supply to any fixed bath to be designed and installed so that the water delivered cannot exceed 48°C. It applies only where a dwelling is erected or formed by a material change of use. Approved Document G adds that the limiting device must not be easily altered by building users.
Source: Approved Document G, requirement G3(4) and paragraphs 3.65-3.66, GOV.UK
What temperature should a hot water cylinder be set to?▼
Health and Safety Executive guidance on legionella control says hot water should be stored at at least 60°C and distributed so that it reaches 50°C at the outlet within one minute, and that cold water should be kept below 20°C. Legionella bacteria multiply between 20°C and 45°C. The duty to manage that risk falls on employers, landlords and others in control of premises.
Source: Hot and cold water systems, Health and Safety Executive
Which plumbing work has to be notified to the water company first?▼
In England and Wales, some installations must be notified to your water supplier before work starts. Regulation 5 of the Water Supply (Water Fittings) Regulations 1999 lists them, including a bath holding more than 230 litres, a bidet with an ascending spray, a pump drawing more than 12 litres per minute, and an automatic garden watering system. Consent is deemed granted if the supplier does not respond within ten working days.
Source: Regulation 5, Water Supply (Water Fittings) Regulations 1999, legislation.gov.uk
Why must cold water pipes be kept away from heat sources?▼
Because cold water is required by law to stay cold. In England and Wales, paragraph 9 of Schedule 2 to the Water Supply (Water Fittings) Regulations 1999 requires any pipe supplying cold water for domestic purposes to any tap to be installed so that, so far as is reasonably practicable, the water in it is not warmed above 25°C.
