Frequently Asked Questions

Find answers to common questions about our plumbing services, pricing, and procedures. We're here to help you understand what to expect.

We handle a comprehensive range of plumbing work for residential and commercial properties. This includes emergency repairs such as burst pipes, severe leaks, and blocked drains that require immediate attention. We also manage routine maintenance tasks like tap repairs, toilet installations, and radiator servicing.

Our team works on complete bathroom and kitchen installations, boiler servicing and repairs, central heating systems, and water heater replacements. We're equipped to diagnose and fix issues with low water pressure, noisy pipes, and drainage problems. Whether it's a minor drip or a major system overhaul, we have the tools and expertise to get the job done properly.

For genuine emergencies such as burst pipes, major leaks, or complete loss of water supply, we aim to have a qualified engineer at your property within 90 minutes during standard working hours. Our response time may extend to 2-3 hours during evenings and weekends, depending on your location in London and current demand.

When you call, we'll assess the urgency of your situation and provide a realistic arrival time. We keep our vans fully stocked with common parts and tools, which means we can often complete repairs on the first visit. For less urgent issues, we typically schedule appointments within 24-48 hours at a time that suits you.

Yes, we provide free, no-obligation quotes for all planned work such as bathroom installations, boiler replacements, and heating system upgrades. For smaller jobs that can be described clearly over the phone, we can often give you an accurate price estimate immediately.

For larger projects, we'll arrange a site visit to assess the work required, take measurements, and discuss your specific needs. This allows us to provide a detailed written quote that breaks down labour costs, materials, and any additional expenses. Our quotes are valid for 30 days, and we never add hidden charges. If unexpected issues arise during the work, we'll discuss them with you before proceeding.

All our engineers hold relevant qualifications including City & Guilds certifications in plumbing and heating. Those who work on gas appliances are registered with Gas Safe, which is a legal requirement in the UK. We maintain comprehensive public liability insurance covering up to £5 million, protecting both you and our team.

Our staff undergo regular training to stay current with building regulations, new technologies, and safety standards. We can provide copies of certifications and insurance documents upon request. After completing work on gas appliances or certain installations, we'll issue the appropriate compliance certificates as required by law.

We accept multiple payment methods for your convenience: cash, all major debit and credit cards, bank transfers, and contactless payments. For larger projects, we can arrange payment in stages - typically a deposit to secure materials, a mid-project payment, and final settlement upon completion.

Payment is due upon completion of the work unless alternative arrangements have been agreed in advance. We'll provide you with a detailed invoice showing the breakdown of all charges. For emergency call-outs, payment is expected on the day of service. We don't require payment before starting work on emergency repairs.

We provide a 12-month guarantee on all labour for standard repairs and installations. This means if an issue arises with our workmanship within that period, we'll return to fix it at no additional charge. Parts and materials come with manufacturer warranties, which vary depending on the product - typically ranging from 1 to 10 years.

For boiler installations, we offer extended warranty options through manufacturer schemes. Our guarantee doesn't cover damage caused by misuse, lack of maintenance, or work carried out by other contractors. We keep detailed records of all work completed, making it easy to track what's covered under guarantee.

Yes, we work with both residential and commercial clients across London. Our commercial services include maintenance contracts for office buildings, restaurants, retail spaces, and small industrial units. We understand that business downtime costs money, so we can schedule work outside regular hours to minimise disruption.

For commercial clients, we offer planned maintenance programmes that help prevent unexpected breakdowns and ensure compliance with health and safety regulations. We're experienced in working with landlords, property managers, and facilities teams. Our engineers carry ID and are respectful of your business environment and customers.

Call our main number and you'll be directed to our emergency service. We have engineers on call during evenings, weekends, and bank holidays. While you wait for us to arrive, turn off your water supply at the stopcock if you have a major leak - this is usually located under the kitchen sink or where the water pipe enters your property.

For burst pipes, try to contain the water with towels and buckets, and move valuables away from the affected area. If water is near electrical outlets or appliances, switch off the electricity at the fuse box. Don't attempt repairs yourself if you're not confident, as this can make the situation worse. Our emergency call-out fee covers the first hour of labour, with additional time charged in 30-minute increments.

Our standard hourly rate is £65 for routine work during business hours, with a minimum charge of one hour. Emergency call-outs carry a fixed fee of £95, which includes the first hour of labour. Simple repairs like fixing a dripping tap typically cost between £80-£120, while replacing a toilet might range from £150-£300 depending on the unit you choose.

Larger projects vary significantly based on specifications. A basic bathroom installation starts from £2,500, while boiler replacement typically ranges from £1,800 to £3,500 depending on the model and complexity of installation. We'll always provide a clear quote before starting work, so you know exactly what to expect. Materials are charged at cost plus a small handling fee, and we can source products to suit different budgets.
