24-hour emergency plumber across South London

Plumbing and heating emergencies do not keep office hours. R.W. Miller is available 24 hours a day, 7 days a week for emergency call-outs across South London — covering SW4, SW8, SW9, SW11, SW12, SW16, SW17, SW18, SE1, SE5, SE15, SE21, SE22, SE24 and all surrounding postcodes. When you call, you speak directly with Reion — a Gas Safe registered engineer (919881), not a call centre or dispatcher.

Emergency call-outs are prioritised. The £80 diagnostic fee applies to the first hour on-site and covers assessment, any immediate safety measures, and a fixed price for the repair. We aim to make the property safe within the first visit — whether that means isolating a burst pipe, restoring heating, or making a gas supply safe.

If you can smell gas or suspect a carbon monoxide leak, call the National Gas Emergency Service on 0800 111 999 first, then leave the property. Once the immediate hazard is made safe by the gas network, call 07375 813996 and Reion will attend to carry out any repairs and restore your gas supply.

Plumbing emergencies we cover across South London

Burst or leaking pipes A burst pipe can release hundreds of litres of water per hour — isolate your stopcock immediately and call for an emergency repair.
Boiler breakdown in cold weather Loss of heating and hot water in winter is a genuine emergency, particularly in households with young children, elderly residents, or medical needs.
Flooding from appliances Washing machine, dishwasher, or sink overflows that cannot be controlled by isolating the appliance supply require urgent investigation of the drainage or supply pipework.
Gas smell inside the property A gas smell inside is a gas emergency — leave the property, do not operate any switches, and call 0800 111 999 before calling a plumber.
Blocked drains causing flooding A blocked soil stack or main drain that is causing sewage to back up into the property is a health hazard requiring urgent clearance.
Loss of water pressure or supply Sudden loss of water pressure or a complete loss of supply may indicate a burst supply pipe or a leak — call to investigate before water damage spreads further.

How we handle emergency call-outs

01

Call Reion directly

Call 07375 813996 at any time of day or night. You speak directly with the engineer — not a call centre. We aim to be on-site across South London within one to two hours for genuine emergencies.

02

Make safe first

The priority on any emergency call-out is making the property safe — isolating the water or gas supply, stopping active damage, and assessing the full extent of the problem.

03

Fixed price before repair

Once the immediate risk is controlled and the fault is diagnosed, a fixed price is agreed for the repair before work starts. The £80 diagnostic fee covers the first hour, including any immediate safety work.

04

Repair and confirm

We carry out the repair, test that the system is functioning correctly, and confirm there are no further issues before leaving. A job sheet is provided confirming everything done.

Frequently asked questions

How much does an emergency plumber cost in South London?
R.W. Miller charges an £80 diagnostic fee for the first hour on-site, including emergency call-outs. This covers the visit, assessment, any immediate safety measures, and a fixed quote for the repair. There are no hidden call-out surcharges — the same fee applies day or night, weekday or weekend.
How quickly can you respond to a plumbing emergency in South London?
We aim to be on-site within one to two hours for genuine emergencies across South London. Response times depend on traffic and our current location, but we prioritise emergency calls above all other work. Call 07375 813996 at any time — Reion answers the phone directly.
What should I do while waiting for the emergency plumber?
For a burst or leaking pipe, locate your stopcock (usually under the kitchen sink or where the supply enters the building) and turn off the water supply. For a boiler breakdown with no gas smell, turn the boiler off at the programmer. For a gas smell, do not operate any switches — leave the property and call 0800 111 999. These steps minimise damage while you wait.
Do you charge more for out-of-hours emergency call-outs?
No. R.W. Miller charges the same £80 diagnostic fee for the first hour regardless of when you call — including evenings, weekends, and bank holidays. The repair price is agreed as a fixed quote before work starts. There are no additional out-of-hours surcharges.
Can you fix a burst pipe on the same visit?
In most cases, yes. We carry repair materials for common pipe sizes and joint types, which means most burst pipe repairs can be completed on the same visit. In rare cases where specialist fittings are required — for example on older lead or copper systems — a temporary repair is made and the permanent fix is completed as soon as parts are sourced, usually within 24 hours.
