About Floodgate Ltd

The concept of a completely removable, flood protection door barrier was first devised by inventor John (Ian) Harrison in the mid 1990’s to help protect his local seaside restaurant from the devastating effect of seasonal high tides. He soon realised he was not alone in needing protection and Floodgate was born.

With help from the University of Wales College Cardiff and the Welsh Office, Floodgate’s became commercially available in 2000 and we are still manufacturing them in Wales today. Floodgate was one of the very first flood protection products to successfully pass the stringent physical tests set by the Environment Agency under standard PAS1188-1:2014 and conducted by hydrologist engineers from HR Wallingford.

Our team has over 50 years experience in handling both domestic and commercial flood protection projects. With over 50,000 units currently providing reliable flood defence throughout the UK, Europe, the Far East, Africa, America and Australasia, we are a world-wide leader in property level flood protection.

Our extensive portfolio of clients include the Environment Agency, local authorities, housing associations, water utility companies, engineering companies as well as the general public.

We are also proud to announce that our management quality systems are certified to ISO9001:2015.

We needed to implement a solution that, in the event of flooding, would buy us time to deal with the cause of the flooding at source, be it a blocked culvert or some other reason, so that we can bring in pumps and other equipment to ensure that everything can continue operating as near normal as possible. The fact that Floodgates can be deployed so quickly and easily by anyone was what attracted us to them as a solution in the first instance.

Project Manager, Gatwick Airport Limited

Floodgates are excellent, they are the only kite-marked solution that we have found that enables us to respond so quickly to flood risk.
The fact that they are completely re-usable is an added bonus making them extremely cost effective. We have evaluated other products but they all require preparatory work on properties before deployment, defeating the object of rapid deployment.

River Inspector for the Coastal Protection and Flooding Unit, Aberdeenshire Council

The way that Floodgate works means that there are no day to day obstructions to the shop which would interfere with the business or customer entry…this has been an ideal solution for me.

Managing Director, Dumfries Scooters

Last year I purchased one of your domestic floodgates. This afternoon we had a most unexpected high tidal surge and it quickly became clear that the water was about to pay us a very sudden visit. As I am disabled and live alone, I phoned a very good friend and in a few minutes we had the Floodgate in place. I am pleased to tell you that not a drop got past the barrier and I am now able to relax. I have every faith in the Floodgate. Many thanks for your brilliant product. There have been a few raised eyebrows this afternoon with questions such as “What! you have no sand bags?” I just say that with Floodgate – “I don’t need sandbags!!”.

Floodgate’s unique design of an expandable gate suited our requirements perfectly, we only needed two different sizes to cope with all our needs…As a not-for-profit organisation, every penny counts and whilst we can’t afford to cut corners, we also need to ensure that we maximise the value of any investment.

We bought two of your Floodgates after the 2007 floods and are very pleased to report that, having had their first proper test since then, they have passed with flying colours. One gate held back 21” of water and avoided approx 4” of water entering our house.

Although we appreciate that insurance companies are businesses that need to balance their risk, it still came as a major shock to find out that they would no longer provide any flood cover whatsoever.
It was fortunate that our brokers had the foresight to look beyond the immediate response and bring in Floodgate to help us come up with a strategy to reduce our risk to insurable levels.

Summer Inns Ltd.

Floodgates have proved to be excellent value for money. Our insurance company reduced our flood excess from £10,000 to £1000 after we sent them photographs of the products in place.

As historic buildings, we are strictly limited in what we can do in terms of modifications to the fabric of the buildings and Floodgates have proved to be the ideal solution, as they required little or no modifications around the openings that we were looking to protect.
