Trusted by businesses and landlords across Hampshire
SMH Plumbing & Heating are Gas Safe registered commercial plumbers serving businesses, landlords, and property managers across Southampton, Hampshire, and the wider South. Whether you need a one-off repair, an annual boiler service, or a planned maintenance arrangement across multiple sites, we’re a local team you can actually get hold of, and one that won’t recommend work that doesn’t need doing.
We work across offices, retail units, industrial premises, HMOs, hospitality venues, and multi-occupancy buildings throughout Southampton, Winchester, Eastleigh, Fareham, Romsey, and the surrounding area. If you manage a commercial property and need a reliable plumbing and heating contractor, here’s what we can do for you.
What we cover on commercial sites
1
Commercial boiler servicing
Commercial boilers run harder than domestic systems and carry significantly greater regulatory responsibility. Under the Gas Safety (Installation and Use) Regulations, gas appliances in non-domestic premises must be maintained in a safe condition — and as the duty holder, that responsibility sits with you.
We service a wide range of commercial appliances, from wall-mounted units in small offices to floor-standing boilers and modular systems in plant rooms. Every service is carried out by a qualified Gas Safe registered engineer and fully documented, so whether your insurer, local authority, or facilities manager asks for records, you’ve got them.

Planned maintenance contracts
Reactive maintenance is invariably more expensive than planned maintenance, and on a commercial site, an unplanned heating failure causes real disruption. For landlords, managing agents, and businesses with critical heating or hot water requirements, we put together scheduled maintenance programmes that keep systems running, compliance records up to date, and unexpected callouts to a minimum.
We work with single-property landlords and multi-site operators alike. If you’ve got several buildings across Hampshire to think about, we can coordinate servicing across all of them on a timetable that works for you.

Commercial plumbing
From new pipework installations and water supply work to leak detection, drainage issues, and burst pipe repairs, we handle the full range of commercial plumbing across all types of premises. This covers both planned installation work and reactive callouts when something goes wrong unexpectedly.
We’ve worked on everything from straightforward office fit-outs in Southampton to more involved jobs across industrial and hospitality premises in Hampshire. The priority on every job is the same: get in, cause as little disruption as possible, and leave everything properly done and documented.
4
Landlord gas safety certificates
If you’re a commercial landlord with gas appliances on the premises, you’re legally required to hold a valid gas safety record, commonly referred to as a CP12.
We carry out the inspections and issue the certificates, keeping you compliant and giving you one less thing to manage. We can also set up reminders so renewals don’t slip through the cracks.
5
Commercial boiler repairs
When a boiler goes down on a commercial site, the pressure to resolve it quickly is real. Our engineers are experienced diagnosing faults across a wide range of commercial appliances, and we’ll give you a clear picture of what’s wrong, what it’ll take to fix it, and how long it will take, without the vague timelines or inflated estimates that seem to come with the territory from some contractors.
Where parts need sourcing, we’ll tell you honestly. Where a repair doesn’t make economic sense against a replacement, we’ll tell you that too.
6
Emergency callouts
When a heating system fails on a commercial site, you need someone who can actually get there.
We cover emergency callouts across Southampton and Hampshire and will always give you a straight answer on timing rather than a vague ETA.
Call us directly on 02380 179 486.
Why businesses across Hampshire choose SMH
We’re a family-run, Gas Safe registered team based in Southampton, not a national company with a call centre fielding your enquiry. When you get in touch, you’ll speak to someone who knows the area and can give you a straight answer about what’s needed.
We don’t mark up unnecessary work. Commercial maintenance budgets get squeezed enough without engineers talking up jobs that don’t need doing, and our reputation in Hampshire has been built over years of doing things the right way. If something needs attention, we’ll say so clearly. If it doesn’t, we’ll tell you that instead.
All commercial work comes with full documentation as standard, service records, gas safety certificates, or whatever your insurer, facilities management team, or health and safety file requires. We understand that on commercial sites, the paperwork matters as much as the work itself.
And because we’re genuinely local, we can turn visits around far faster than you’d expect. If you’ve been let down by a contractor that promised the earth and then disappeared, give us a call.
Some frequently asked questions
How often does a commercial boiler need servicing?
As a minimum, annually, but for high-usage systems or premises with continuous heating or hot water demand, more frequent servicing is advisable.
Regular servicing also supports your obligations as a duty holder under gas safety legislation and ensures your warranty remains valid. We’ll advise on the right interval for your specific system during an initial visit.
Do you work on all types of commercial premises?
We work across offices, retail units, industrial buildings, HMOs, hospitality venues, and multi-occupancy residential properties across Southampton and Hampshire.
If you’re unsure whether your premises falls within our scope, just give us a call, we’re happy to talk it through before you commit to anything.
Can you manage maintenance contracts across multiple sites?
Yes. We work with landlords and property managers running portfolios across Hampshire and can coordinate servicing schedules, compliance records, and callout cover across multiple properties.
It’s easier than dealing with a different contractor for each site, and you’ve got one point of contact for everything.
Are you Gas Safe registered?
Yes, all engineers carrying out gas work on our team are Gas Safe registered. We can provide registration details and documentation on request.
How quickly can you respond to a commercial callout?
We’ll always give you a realistic answer rather than a promise we can’t keep.
For urgent situations, call us directly on 02380 179486, and we’ll do our best to prioritise you. We’re local, so we’re not routing engineers across the country to reach you.
What documentation do you provide after a service or repair?
We provide service records and gas safety certificates as standard on all relevant work.
If you have specific requirements for your insurance, H&S files, or facilities management records, let us know upfront, and we’ll make sure the paperwork is in order.
What's the difference between a CP12 and a standard gas safety check?
A CP12, formally a Gas Safety Record, is the legally required annual inspection and documentation for landlords with gas appliances.
A general gas safety check is broader and can be carried out as part of a service or risk assessment. If you’re a commercial landlord, you need a CP12.
If you’re unsure what applies to your premises, we can advise.
