Commercial diving, ROV inspection and confined space work for UK water companies and their contractors. Based in Epping, Essex, working across the UK.
What We Do
Marine Services Built for the UK Water Industry
Marine inspection, commercial diving and confined space work for water companies and their contractors
MMP Marine & Inspection is a marine inspection company and specialist marine contractor working for water companies and water utility contractors across the UK. Our team has over 75 years of combined experience in the water industry, and has developed survey methods that reduce costly shutdowns and the need for manned entry. Your assets stay in service while the work is done safely.
We work on sewage treatment works, service reservoirs, tunnels, pipelines, culverts and underground chambers. On each site we pick the right mix of commercial diving, remote ROV surveys and confined space teams, so you get the inspection, repair or installation you need with the least risk.
We are an HSE-registered diving contractor, full members of the Association of Diving Contractors (ADC), and certified to ISO 9001 and ISO 45001. Our confined space operatives are City & Guilds certified.
Our Marine Services
ROV Inspection and Pipeline Inspection
Our ROVs and fibre optic crawlers inspect pipelines and tunnels up to 2km from a single access point, with no need for confined space entry. Every survey includes live CCTV, with sonar and 3D LiDAR available.
Commercial Diving Services
We are an HSE-registered commercial diving contractor working in fresh and contaminated water. Our dive teams carry out underwater inspection, NDT, welding, thermic lance cutting, debris removal and valve replacement.
Confined Space Entry and Rescue
When manned entry can’t be avoided, our City & Guilds certified teams plan and carry it out in line with the Confined Space Regulations 1997, with a trained rescue team on hand.
Our Approach
Built for the Water Industry
Our founders worked across commercial and military diving, and saw the same problems come up again and again in the water industry, from strict inspection requirements to costly shutdowns. Water companies needed safer, more efficient ways to look after their critical infrastructure.
MMP Marine & Inspection was set up to meet that need: a specialist among water industry contractors, offering practical, tailored marine services that cut downtime and cost while keeping safety and compliance first.
That risk-managed approach runs through all our marine civil engineering and inspection work, from asset inspection and confined space entry to ROV surveys, commercial diving, isolation plates and cofferdams. Read our water industry case studies to see it in practice.
What Our Clients Say
“We were so impressed with the work of MMP Marine & Inspection on their installation of the Blackfriars flume. We have worked collaboratively with MMP for a long time now and they never fail to get the job done in a timely, efficient and, most importantly, safe manner. Their work on Blackfriars flume even resulted in an award for efficiency from Tideway, a testament to their craft. We have full confidence in MMP and look forward to a long and mutually beneficial partnership with them.”

Marine Inspection FAQs
What do your marine inspection services cover?
We inspect water industry assets that sit underwater or underground, including reservoirs, pipelines, tunnels, culverts, outfalls and chambers. Depending on the site, we use commercial divers, ROVs, fibre optic crawlers, sonar or confined space teams.
Do you work outside Essex?
Yes. We are based in Epping, Essex, and work for water companies and their contractors across the UK.
Can you inspect assets without shutting them down?
Often, yes. Our ROVs work in static, surcharged or fast-flowing water and can survey up to 2km from one access point, so many inspections happen while the asset stays in service.
What accreditations do you hold?
We are an HSE-registered diving contractor and full ADC members, certified to ISO 9001 and ISO 45001, with City & Guilds certified confined space operatives.
