Installing & managing complex safety systems- for buildings that can't afford failure.
Fire alarms, sprinkler controls and electrical infrastructure, designed, installed and maintained by a team that turns up, documents the work, and stays for the long haul.
A small firm with large-site experience.
WSD was established in 2021 by three engineers with over forty years of combined experience between them. We exist to design, install, commission and maintain complex fire and electrical systems, and to leave the documentation in better shape than we found it.
We’re knowledgeable, professional, and present every step of the way. That’s not a slogan; it’s why our clients keep us on long after the install signs off.

Ben South
Director · Sprinkler leadSprinkler-side since 2008 and the engineer most likely to be on the end of the phone after hours. Gives every job the answer he’d want himself.

Got questions? We've answered the common ones.
Quick answers on cover, callout times, accreditations and what working with us actually looks like. Still got a question? Get in touch.
Do you offer 24/7 emergency call-out?
No. Reactive call-out is available during office hours (9am to 5pm, Monday to Friday). If you need round-the-clock cover for fire and life safety faults, we’ll be honest about it and help you find a provider who specialises in that.
Do you cover domestic / home smoke alarms?
No. WSD is a commercial fire and electrical contractor. If your home smoke alarm is beeping (typically a dying battery), the answer is usually replacing the battery or the whole alarm, and a local electrician or the alarm manufacturer’s customer service is the right route.
What’s the difference between maintenance and reactive work?
Maintenance is the scheduled, planned servicing in your contract — quarterly visits, annual full tests, certification and the rest.
Reactive work is anything that arises between visits: a fault, an alarm, a callout. Reactive work for contract clients is prioritised and typically billed at a contract rate. Reactive work for non-contract clients is available case-by-case at standard rates.
Do you cover the whole UK?
Yes, we deliver maintenance contracts and projects nationally from our Bromsgrove HQ. Most of mainland Britain is within a routine response window for reactive maintenance work.
Sites further from the Midlands may have slightly longer response windows for reactive call-outs; we can provide a map of typical response times by area during the initial survey if it’s relevant to your site.
Are you fully insured and accredited?
Yes. We hold BAFE, NICEIC, FIA, BSI and SafeContractor accreditations.
Insurance: £5m public liability, £10m employers liability, £1m professional indemnity, £5m product liability. Certificates available on request.
Do you offer ongoing maintenance contracts?
Yes. Most of our clients move onto a planned maintenance contract either after installation or as a takeover of an existing system. Service intervals, certification, response windows and reactive scope are agreed up front and documented in the contract.
Can you take over an existing system installed by someone else?
Yes. We routinely take over the maintenance of systems originally installed by someone else.
We carry out an initial survey and full functional test of the existing system first, give you a written baseline of what’s there and what condition it’s in, then quote against bringing it onto an ongoing maintenance contract. The survey is quoted separately to the contract, so there’s no commitment until you’ve seen the findings.
How quickly can you respond to a callout?
For clients on a maintenance contract, reactive call-outs are prioritised and attended within agreed response windows during office hours (9am to 5pm, Monday to Friday). For ad-hoc call-outs without a contract, we attend as soon as our schedule allows, typically same-week for non-critical work.
WSD doesn’t operate a 24/7 emergency response. For sites that need round-the-clock cover we’re upfront about that and can point you to providers who specialise in it.
