Portsmouth Commercial Plumbing, Heating and Drainage

Murphy’s Law states that “anything that can go wrong will go wrong” but why increase the chances of proving Mr. Murphy right? Leaving plumbing, heating or drainage systems to age and become run down or totally malfunction is not the best way to run a business as even the smallest of breakdowns in service can have calamitous effects. No 1 PHD has been maintaining and installing the most efficient and cost-effective utilities services to business owners in the Portsmouth area for years and can do the same for you. No matter which business sector you are involved in, No 1 PHD can install the best and most suitable plumbing, heating and drainage systems for your particular requirements and also provide a first class maintenance service to keep any current or new systems operating smoothly.

Commercial Plumbing Experts

Different businesses have different requirements and our team of plumbing experts are well aware of this fact. There is no “one size fits all” plumbing system and we treat each new plumbing installation on its individual merits. An office block or hotel needs to cater for numerous guests, visitors and clients and the plumbing system we design and install will reflect this. On the other hand, a much smaller, but still complex network, of pipes, drains and fittings will be required to meet bars and pubs plumbing requirements. Big, small, simple or complex plumbing systems and networks, the No 1 PHD team has installed and serviced them all for our clients in Portsmouth and beyond.

Commercial Heating Services

Controlling and maintaining an ambient temperature throughout any business premises is crucial to the smooth operation of any enterprise. Equally important is a dependable supply of hot water. Should either of these go awry or fail to function completely the result is unhappy staff, customers and loss of profit. The hassle and stress caused by incorrectly functioning heating and hot water can be avoided by using No 1 PHD’s commercial heating services which will not only install state-of-the-art heating systems but also carry out regular maintenance to ensure that everything is functioning to its optimum. Installation, repairs and maintenance are all part of the heating services we have been supplying in Portsmouth and Hampshire down through the years to our clients’ complete satisfaction.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
