What Our Commercial Plumbing Services Cover

Commercial properties have very different plumbing demands to residential homes. Higher daily usage, regulatory obligations under the Water Supply (Water Fittings) Regulations 1999, Legionella risk management responsibilities, and the need to keep disruption to an absolute minimum — these are factors that require a specialist approach.

Our commercial plumbing offer spans the following areas:

Our Commercial Plumbing Services in Detail

Commercial Boiler & Water Heater Servicing

Commercial boilers work far harder than domestic ones, and the consequences of a failure are far more serious. A heating or hot water outage in a care home, hotel, restaurant, or office block can mean closing your doors.

Who needs it? Restaurants, offices, hotels, care homes, gyms, schools, managed blocks — any commercial property that relies on a boiler or water heater for daily operations.

What’s included: Annual safety inspections, flue gas analysis, pressure and control checks, heat exchanger cleaning, gas valve testing, fault diagnosis, and certification. We also carry out interim reactive repairs and emergency callouts between service visits.

Our engineers are Gas Safe registered and familiar with a wide range of commercial boiler brands and systems, from wall-hung condensing units to large commercial cylinders and pressurised systems.

Blocked Drains & Commercial Drain Clearance

A blocked drain in a commercial kitchen or busy washroom can create hygiene risks, enforcement notices, and reputational damage very quickly. We offer rapid commercial drain unblocking across London, using high-pressure water jetting, manual rodding, and CCTV inspection to find and fix the root cause — not just the symptom.

Who needs it? Restaurants and food businesses, office buildings, retail units, managed residential blocks, schools, and any property with shared drainage.

What’s included: Emergency and planned drain clearance, CCTV drain surveys, root intrusion removal, drain descaling, sewer lining, and written reports with video footage for compliance records.

Emergency Commercial Plumbing

Burst pipes don’t care that it’s Sunday morning. A failed stopcock doesn’t wait for business hours. Our 24/7 emergency commercial plumbing service covers the whole of London and is designed to get a qualified engineer to your premises as quickly as possible — day or night, weekday or bank holiday.

Who needs it? Any commercial property manager, facilities team, or business owner who can’t afford to wait until Monday.

What’s included: 24/7 dispatch, rapid response to burst pipes, major leaks, boiler failures, loss of water supply, sewage backups, and frozen pipe emergencies. On arrival, we’ll make safe, contain the damage, and provide a clear plan of action.

Pipe Replacement & Relining for Commercial Properties

Older commercial buildings often have ageing copper, iron, or lead pipework that’s corroding, scaling, or prone to failure. Rather than disruptive full replacement, pipe relining can extend the life of your existing infrastructure significantly — and in many cases it can be completed without digging up floors or disrupting your business.

Who needs it? Commercial landlords, property developers, facilities managers, and businesses in older London buildings with recurring leak or pressure issues.

What’s included: Survey and diagnosis, pipe relining using CIPP (cured-in-place pipe) methods, full pipe replacement where relining isn’t appropriate, system flushing, and pressure testing on completion.

Commercial Annual Maintenance Contract (AMC)

The most cost-effective way to manage your commercial plumbing is to stay on top of it before things go wrong. Our Commercial AMC gives you a dedicated maintenance partner — scheduled inspections, priority response, compliance documentation, and a single point of contact for all your plumbing and heating needs.

Who needs it? Landlords with multiple properties, commercial property managers, housing associations, hospitality businesses, and any organisation that wants to manage costs and compliance proactively.

What’s included: Agreed number of planned visits per year, written inspection reports, priority emergency response, discounted labour rates for reactive work, Legionella risk assessment support, and Gas Safe certification for gas appliances.

Planned Preventive Maintenance (PPM)

PPM goes hand in hand with our AMC offer. Rather than waiting for a fault to appear, we work with you to create a scheduled maintenance calendar that covers every element of your plumbing and heating infrastructure — keeping you compliant, protected, and fully operational.

Who needs it? Facilities managers, large commercial landlords, schools, care homes, and any organisation with regulatory obligations around water hygiene, gas safety, or building maintenance.

What’s included: Custom PPM schedule, scheduled engineer visits, written compliance records, appliance servicing, Legionella monitoring support, and annual reporting packs.

Why Professional Commercial Plumbing Matters in the UK

Commercial properties in England and Wales operate under a distinct set of regulatory and legal obligations that simply don’t apply to private residences. Getting this right isn’t optional — it’s a legal requirement.

Water Supply (Water Fittings) Regulations 1999 require that all water fittings installed in non-domestic premises meet specific standards to prevent contamination and waste. Non-compliant installations can result in enforcement action by your water authority.

The Control of Substances Hazardous to Health (COSHH) Regulations and the HSE’s Approved Code of Practice for Legionella (L8) place a legal duty on commercial property owners and operators to assess and manage the risk of Legionella bacteria in water systems. Failure to comply can result in prosecution, fines, or — worse — a genuine public health incident.

Gas Safety (Installation and Use) Regulations 1998 require that all gas appliances in commercial properties are serviced annually by a Gas Safe registered engineer, and that records are maintained.

At Catalyst Home Services, our engineers understand these obligations. We carry out work to the correct standard, provide the documentation you need, and will flag any compliance concerns we spot during a visit.

FAQs

Do I legally need to have my commercial boiler serviced every year?

Yes. Under the Gas Safety (Installation and Use) Regulations 1998, all gas appliances in commercial and non-domestic properties must be inspected and serviced by a Gas Safe registered engineer at least once a year. Records must be kept and, in some cases, provided to tenants or employees. Failure to comply can result in prosecution and significant fines.

What is Legionella risk management, and does it apply to my business?

Legionella bacteria can proliferate in water systems that are poorly maintained or where water is stored at the wrong temperature. The HSE’s Approved Code of Practice (L8) requires all commercial property operators to carry out a Legionella risk assessment and implement a written control scheme. This applies to virtually any business with a water system — offices, hotels, care homes, and more. Our engineers can carry out assessments and ongoing monitoring as part of an AMC contract.

Can you work around our business hours to minimise disruption?

Absolutely. We understand that shutting down operations for plumbing work isn’t always an option. We regularly carry out commercial plumbing work in the early morning, late evening, and at weekends to fit around our clients’ schedules. Just let us know your constraints when you get in touch.

How quickly can you respond to a commercial plumbing emergency?

We operate a 24/7 emergency line and aim to have an engineer on site as quickly as possible. Response times vary depending on your location within London and time of day, but we treat commercial emergencies as a priority — especially where a water leak or heating failure is affecting your ability to trade.

What areas of London do you cover for commercial plumbing?

We cover Greater London and surrounding areas. See our full list of service areas →

What is an Annual Maintenance Contract, and is it worth it for a small business?

An AMC is a pre-agreed service programme where we carry out scheduled inspections and maintenance visits throughout the year, with priority response for reactive work. For small businesses, the main benefit is cost predictability — you know what your plumbing maintenance will cost annually, and you avoid the expense and disruption of emergency callouts. Many clients find that the AMC pays for itself after just one prevented emergency. View our AMC packages →

Are your engineers Gas Safe registered?

Yes. All of our engineers who carry out gas work are registered with Gas Safe — the official body for gas safety in the UK. You can verify any of our engineers on the Gas Safe Register. We also hold other relevant industry qualifications and certifications. View our licences and certifications →

Can you provide compliance certificates and written records after each visit?

Yes, always. For gas work, we provide Gas Safe certificates as standard. For broader maintenance visits, we provide written reports detailing what was inspected, any work carried out, and any recommendations. These records are important for your own compliance obligations and are provided as part of every job.
