FAQs

Common plumbing & gas questions

Can't find your question here? Call us — we're happy to advise before you commit to anything.

Most plumbing jobs in South London cost between £80 and £400 depending on the type and complexity. A call-out to fix a dripping tap or isolation valve typically costs £80–£150. Replacing a toilet, fitting a new radiator, or fixing a concealed leak is usually £150–£350. Boiler services start from around £80–£120. We always provide a clear price upfront — no surprises on the invoice.
A dripping tap is usually caused by a worn washer, O-ring, or ceramic cartridge. On older taps, replacing the rubber washer is a straightforward DIY job if you're comfortable turning off the water supply. On modern mixer taps, the ceramic cartridge is a little more involved. If the drip keeps returning after a washer change, or the tap body itself is cracked, it's worth calling a plumber — a continuously dripping tap can waste thousands of litres of water a year.
Landlords in England are legally required to have a Gas Safety Record (CP12) for every rental property, renewed annually. This covers all gas appliances, pipework and flues. Homeowners are not legally obliged to have one, but it is strongly recommended when buying or selling a property, after a boiler installation, or if you haven't had your appliances checked in several years. Only a Gas Safe registered engineer like Nasser can issue a legally valid certificate.
Yes — Nasser is Gas Safe registered, which is the legal requirement for anyone carrying out gas work in the UK. You can verify registration at any time on the Gas Safe Register website using our engineer's details. We carry our Gas Safe ID card on every job and are happy to show it before any gas work begins.
Manufacturers recommend an annual boiler service — and most boiler warranties require it to remain valid. A service typically takes 45–60 minutes and involves checking the heat exchanger, burner, flue, seals, and controls. An annual service catches small faults before they become expensive breakdowns, improves efficiency, and ensures your boiler is safe to operate. We service all major boiler brands including Worcester Bosch, Vaillant, Ideal, and Baxi.
First, check the obvious: is the boiler displaying an error code? Check your boiler manual for what it means. Is the gas supply working — try another appliance? Is the pressure too low — the gauge should read 1–1.5 bar when cold? Has a circuit breaker tripped? If none of these resolve the issue, call a Gas Safe registered engineer. Don't attempt to open the boiler or tamper with the gas supply yourself — it is illegal and dangerous.
Yes — we take emergency calls for burst pipes, major leaks, and loss of heating or hot water. For a genuine emergency like a burst pipe, turn off your stopcock first to limit the damage, then call us on 07474 686888. We aim to reach most Croydon and South London addresses quickly and will always advise over the phone on what to do while we're on our way.
Yes — we handle full bathroom installations including bath, shower, toilet, basin, and all associated plumbing. We can work from your chosen sanitary ware or help you source suitable products. We manage the full job from stripping out the old suite to final commissioning and leak-testing — you don't need to co-ordinate multiple tradespeople.
Based in Croydon, we cover the surrounding South London area including Sutton, Bromley, Mitcham, Streatham, Thornton Heath, Purley, and Coulsdon. If you're just outside this area, give us a call — we'll usually be able to help.
