I employed h2o plants to build my pond last year in 2016 The work was carried out from planning to after care with expertise and efficiency Great care was taken to provide me with the correct equipment for my pond and gardens needs and requirements. I now have a beautiful 9 foot deep 5x3 meter koi pond with a fantastic filtration system and beautiful coping stones and brickwork surround. It is the feature of my garden and home. The works from digging the massive hole with diggers right down to the finishing coping stones were carried out expertly through out the entire process. The knowledge of the filtration system and fish is excellent. And the aftercare is second to none. I highly recommend h2o plants for any type of pond installation and or maintenance. They have been superb throughout. And I would like to thank them for making my pond the centre piece of my garden and my koi happy. A very happy customer Stephanie Valente

Billy is everything you would want if you have a pond – diligent, customer-focused, knowledgeable and good to have around. Fully recommend H2O


Phillip Cooke Hemingford Abbots, Huntigdon pump replacement, 2017
'My garden pond had got into a dreadful mess. Neglected for many years, the top of its fountain long lost in the watery depths, followed by numerous layers of fallen leaves, and more recently completely clogged up with the debris from a major pruning of adjacent hedge and tree, topped by a thick layer of algae, it was a sorry sight, and I doubted whether it could any longer be supporting organic life. But Jimmy of H2O Plants has rescued and completely redeemed it. With the minimum of fuss and the maximum of care, he thoroughly cleaned out the morass, salvaged the fountain top as well as two frogs and a newt, installed several attractive potted plants and an oxygenating one, refilled the pond, and reset the fountain -- all as good as new. Wonderful, and at a very reasonable charge, not to mention some very useful free advice on future upkeep. Strongly recommended. Dr Richard Allen.'

I have used Billy several times over the past few years and I highly recommend him. I inherited a pond which I knew very little about and he has been invaluable with his knowledge and service. He really enjoys his work and nothing is too much trouble. My pond is a real feature in the garden now, thanks to Billy. PS – fish looking much healthier now and I haven’t lost any as a result of treatment just yet 😊



Wendy McDougal Saffron Walden, Essex pond re lining with GRP, 2017
This firm has cleaned out the pond in my garden for the last three years. The owner, Billy Hancock, is a friendly, efficient and highly skilled aquatic worker. He always arrives at the time agreed and sets about unloading and installing his equipment with minimum fuss. He takes care to place the fish, frogs and newts in a holding tank of clean water while he drains the pond before both power-hosing and scrubbing down the lining. He carefully removes the plants and ensures their roots are pruned before they are replaced. He cleans the pump out and checks that it is left in good working order. He is always willing to offer helpful and knowledgeable advice about any aspect of pond maintenance (suitable plants, the most appropriate pumping and filter system, and the care of pond life generally) should you need it. He leaves the pond surrounds clean and tidy when he departs. I have already booked in my annual spring clean for next year, which helps us both to plan ahead. His is altogether a most professional firm and I have no hesitation in fully and strongly recommending Billy Hancock to others. Professor Ian Gordon, Cambridge.

My inner city pond was in a very poor state, full of bubbling methane, silt and rotting vegetation, and with almost nothing except blanket weed alive in there. Billy did a superb job cleaning it out and re-housing my various water plants. Even better, he was able to save the water in 2 big tanks on the street (the neighbours were very interested) and pump it back in, thereby avoiding chlorinated water. I can now watch the plants on the bottom growing, 5 feet down. Many thanks Billy, a highly recommended service.

If you're like me and have a lovely pond, great fish but no time or knowledge on how to look after them then Billy is your man! When it got to the stage when things were out of hand and the pond was so dirty you couldn't see any fish it was time to turn to the experts. I read with interest the previous testimonials and have to say every good comment made is absolutely true. I now have a new filtration system, that works, and pond water so clean you could drink it!! Maintenance going forward is simple and less often and the fish have never been happier. Best decision I made so if you are experiencing the same situation don't hesitate get Billy in Gary, Great Sampford, Essex

Having had the pleasure of help from Bill senior in 2011 to move my late Dads fish we didn't hesitate to contact H2O again when we needed our 12 Koi rehoming due to pond problems. Billy kindly moved the Koi with care & kindness to his holding tanks where they were not stressed at all , happily swimming around. We were upset initially to let them go but he showed us where they were to be homed which went along way to make us happy knowing they will be together in fantastic ponds. We thoroughly recommend Billy , his care & professionalism is second to none , we are extremely greatful & look forward to seeing them one day on a webcam . Once again Thank you so much for you excellent service Stephen & Sandy Jimson Wisbech Cambs

I have recently had the wonderful Billy clean both my ponds which was certainly needed they now look spectacular thanks to him. He is such a nice friendly person and no job is too small or big he just gets on with it and if you have a slight problem and phone him he will talk it through with you which is a great help. I cannot thank him enough for making it so easy for me to manage and anyone who needs pond assistance should contact Billy every pond owner should have him.
Julie pond clean Enfield, London, 2016
Billy was recommended to me by a local aquatic company in crews Hill after the company I used to build my pond had constructed it in such a way that I couldn't change the UV. He dealt with it quickly, efficiently and at a reasonable price. Over the last couple of years I used Billy regularly to sort out any problems that I encountered. Recently, the UV's just didn't seem to clear the pond no matter what I did. Back came Billy, without rushing into anything rash and costly he tried many things to eradicate the problem until for a reasonable sum came up with a solution. I was sceptical at first, but how wrong I was. Within 7 days my large pond is now virtually clear. What can I say , great guy and a great service. Thanks Billy
Darren Shipton Cuffley, Hertfordshire Koi Pond, 2016
Hi Billy I would like to thank you for the wonderful service you provided when you fitted my new pond filter which I was dreading the upheaval. But you made it so easy for me and the pond has already improved which is fantastic. I would have no hesitation in recommending you for your wonderful work and above all your friendly and professional manner. Thank you so much
Julie new filter Enfield, London, 2016
I needed help with the pond after my husband died and Bill was so very efficient and helpful, a credit to the company. It put my mind at rest knowing the fish were going to a good home and such a help getting the pond drained. I could then get family to help fill it in and turn it into a beautiful area in the garden. Thank you Bill. Would definately reccommend this company to anybody.
Lynn fish removal Walthamstow., 2016

To whom it may concern. We have used Billy’s services for a couple of years covering two ponds, one 3,250 gallons and a second 20,000 gallons.

The smaller pond houses large specimen koi carp

and the larger a number of fish breeds all of significant size. The latter pond has heavy water planting supplied by Billy.

Billy looks after the ponds generally including the water quality, filtration systems, planting and all ancillary functions. In all dealings we have found Billy to be proficient across the full spectrum of services and to be highly knowledgeable.

He is easy to work with and always happy to give an opinion or advice over the phone, inside or outside of normal business hours. We have no hesitation in recommending Billy for all pond construction and maintenance matters.

Hi Billy I'm pleased to be able to say that you have been efficient and reliable over the years that you have been looking after me. Your knowledge and attention to detail has been very refreshing.

I am Thoroughly pleased with the service Billy provides in maintaining our fountain. He is always reliable and very knowledgeable about his job and always gives great customer service! Thanks to him our fountain has remained in very good condition and continues to work well!
Lucy Butcher: Britannia Hospitality Ltd, 2016
Dear Billy, once again thank you for doing such a fantastic job of cleaning my rather dirty pond, replacing UV light bulb, removing the redundant safety grid and mending my leaking filter. You and your team were punctual, quick and efficient, and left everything very tidy which was much appreciated. You also gave me good advice regarding what I suspected was a leak in the pond, but you rightly thought was just due to too many plants. The pond looks better than it has done for years, and I'm sure the fish must think they've died and gone to heaven. It is nice to be able to see them clearly for a change, too. I thought you charged a fair price for the considerable amount of work that needed to be done, and I would have no hesitation in recommending your services to anyone else with a pond in need of cleaning! regards Judith Abbott
Judith Abbott Pond clean Hatfield Peveral essex, 2015

Our pond was in a sorry state, overgrown with reeds, the pump not working, hence the cascades not working. H2O plants removed the old vegetation, cleared out the pond, took care of the wildlife, mainly newts, and set about restoration. It was a professional job, with the results being extremely pleasing for our residents and staff. Moving water, rippling sounds a calming and restful experience for us all.

Thank you.

Roger, maintenance manager.

H20 Plants completed an outstanding project on our old and redundant pond. The pond had been neglected and untouched for 6 years with extensive wildlife growing and broken electrics. Billy Hancock and his team worked so hard in clearing the area and bringing it back to a presentable and pleasurable state. The staff and students of Eastbury Comprehensive School are overjoyed with the renovated pond and are extremely grateful to Billy for delivering what he promised. I fully recommend this company as their knowledge and understanding is vast and they work very conscientiously with a warm and friendly approach". Shelley Jewers, Business Manager

Billy was recommended to me by a mutual friend as Ineeded someone to help move my koi from my old house to my new house about three years ago. After a telephone conversation he visited my home, looked at the pond/fish and said the job was not a problem for him and when would i like it to be done? He seemed very confident baring in mind some of my fish were over 40lb!



The day of the move came and Billy arrived with his transportation tanks with oxygen and every fish was moved with great care and expertise. The job was made to look easy by someone who knew what he was obviously doing.

The new pond that I built had been up and running for two summers by the next time I called Billy due the fact that I had been getting plagued with blanket weed ever since its first months and this was causing the Japanese matting to get pushed out of the filters and overflow in my pump room, the bottom drains were becoming blocked and the pond didn’t look how i wanted it or how it should have looked.

I called Billy to come back, have a look and give me his advice on why he thought this was happening. Straight away he look at the filters i had been recommended to install by a well known aquatic centre and stated that they weren’t man enough for the job. I asked him to work out what he thought would solve the problems and come back to me. A few days later the quote came back with his recommendations.

The equipment was all state of the art and included the use of centrifugal filtration and a bead filter in replacement to some of the old vortex chamber filter units i had. This type of filtration were new to me so i asked Billy what type of guarantee he would give as to whether it would solve the previous. issue of the blanket weed growth “If it doesn’t work I’ll give you your money back!” came his reply. I couldn’t really lose so I commissioned him to carry out the proposed works.

The start of the works arrived and Billy and his team turned up, set up a holding tank with filtration, drained the pond, moved the koi to the holding tanks, cleaned the pond, unblocked the bottom drains by jetting them out and removed the old filtration that was not needed on day one.

Day two arrived and the installation took place of the new superbead filter (inclusive of bacteria to quickly mature the filter), multicyclone filter, new filter media to the existing vortex chambers, the quartz sleeves were cleaned and the bulbs on my UV clarifier units were all replaced.

The pond was now ready to re fill so on went the de-chlorinator cartridge and the tap was switched on. Day three and the pond was filled up and the new equipment was ready to be put into action. Billy switched on the pumps and everything was working fine.

Over the next week Billy returned on a daily basis to install a few fish at a time to the pond and take water quality tests to make sure everything was going to plan. Once the works were finished Billy invoiced me and the works had came in under the original cost as he had done the project in under the time he had first said which is always a bonus and not very common today.

Billy now visits the pond every other week throughout the year to carry out the regular pond maintenance, the blanket weed has never returned, my fish look better than ever and i have also just commissioned him to fibreglass another pond on a project I'm working on at the current time. Using Billy and his team to either build or maintain your pond will be the best choice you make!

Dear Billy, I would just like to say thank you very much for making the relocation of my fish such a stress free event. I was quite anxious about the whole thing, especially as there were so many of them and they were travelling all the way from London to Coventry, but your smooth and efficient operation and the speed with which it was done alleviated all my concerns and my fish are now swimming happily around in their new home having suffered only the minimum of discomfort. I’ll be in touch when I need you again and I would definitely recommend you to anyone who has fish to move! Kindest Regards, Sharon

Dear Billy and team, I wanted to write to say thank you for your donations of materials, time and effort in order to help the Friends Of Itter Park build their wildlife pond and bog garden - our local SWAT project for BBC Springwatch. It'll take some time to settle in - but when we left this afternoon, already the local wildlife were making use of it! To those of you who were there today - particular thanks for giving up your Sunday to help us pass on the 'do one thing for nature' message. The pond and bog garden at Itter is something we will continue to feature across our programmes and local website - your help today means a lasting legacy on and off the air. Best wishes and thanks to you all, Sue
