Commercial in London
We can review commercial enquiries from property managers and businesses. Registered subcontractors carry out and sign off any gas work under their own registration and company name. Scope, specialist availability and a quote must be confirmed before booking.
Define the premises and the trade required
A shop with a leaking supply pipe, an office with an electrical fault and a managed building with a gas appliance need different specialists and access plans. Tell us the premises type, postcode, affected area and what has stopped working. SJW reviews commercial plumbing, electrical and gas enquiries, then checks whether suitable cover can be arranged; registered subcontractors carry out and sign off any gas work under their own registration and company name.
Include what equipment or rooms are affected, whether the issue interrupts occupancy or trading, and any existing service records that explain the system. Photos and a short description can guide the initial conversation without replacing a site assessment. We will distinguish an immediate fault enquiry from a planned alteration or inspection so the proposed quote does not silently combine unrelated work.
Plan site access and responsibilities
Commercial premises may need an authorised contact, plant-room keys, parking information or an agreed access window before a specialist can inspect the work. Tell us about shared services, tenants and building-management rules at the enquiry stage. For gas-related work, SJW arranges suitable registered subcontractor cover; the subcontractor assesses the specific appliance and task before carrying out and signing off gas work under their own registration.
If the fault affects other occupiers or involves water near electrics, isolate the affected area only where safe and use the building's established safety procedure. Do not ask unqualified occupants to open gas appliances or electrical equipment. Explain any immediate hazard when you contact us so we can assess the appropriate first step, rather than promise a particular arrival time or that every trade can attend together.
From enquiry to defined work
We first check the requested trade, premises details and specialist availability, then confirm an assessment or quote before booking. A site finding may change the scope: a visible plumbing repair may uncover a hidden leak, while a gas appliance issue may require further tests or a part. Registered subcontractors carry out and sign off gas work under their own registration and company name; SJW does not issue their gas records.
Ask for the proposed work, access needs and any separate inspection or follow-on quote to be identified clearly. If your property manager needs a record for a contractor file, say which record is required before the visit. Any gas paperwork depends on the registered subcontractor's inspection and is issued under that subcontractor's company name; no certificate or satisfactory outcome is guaranteed by an enquiry.
Pricing, disruption and next steps
Commercial work is quoted for the actual site and scope; this page offers no fixed gas price or direct booking. Share the site address, a contact who can approve work, access restrictions and relevant equipment information so we can discuss a suitable assessment and its charge. If work must be coordinated around occupants or opening hours, raise that before the quote; we will check availability rather than promise out-of-hours cover.
A diagnostic visit may identify parts, specialist testing or additional repairs that were not included in its initial scope. Keep the findings and agree a separate follow-on quote before further work is authorised. For gas work, the registered subcontractor performs and signs off the agreed task under their own registration and company name; for other trades, ask us to identify the responsible specialist and any records needed for your building file.

Frequently asked questions
How do I open a corporate account?
Request a quote and tick "corporate account", or call 0203 0515337. We set up your portal login and account manager.
Do you work out of hours for businesses?
TODO(Roy): confirm out-of-hours cover for commercial clients.
What details help you assess a commercial enquiry?
Give the premises type and postcode, affected system, symptoms, site contact, access restrictions and relevant records or photographs. We will check the trade and quote scope; registered subcontractors undertake any gas work under their own registration.
Can you coordinate access with a property manager or tenant?
Tell us who can authorise access and any site rules when you enquire. We can discuss a suitable arrangement once the specialist, scope and appointment are confirmed; gas work is carried out and signed off by registered subcontractors in their own company name.
Can I request a commercial gas check and electrical inspection together?
List each inspection and the equipment involved. We will assess whether suitable specialists can be arranged and quote each agreed scope; a registered subcontractor performs gas checks and issues any resulting gas paperwork under their own registration and company name.
Do you guarantee out-of-hours attendance?
No. Explain the operational impact and any permitted access window. We will check specialist availability and confirm the proposed time and charge before a visit is agreed.
How is additional work approved after a site visit?
Ask for the findings and a follow-on quote before authorising further work. A diagnosis does not include unspecified parts or repairs; registered subcontractors remain responsible for carrying out and signing off any gas work under their own registration and company name.
