Jon ventured into the world of drainage when he began his career as a plumbing and drainage apprentice at the tender age of 18, and has continued in this field for 32 years.

His initial position was with a company owned by a family friend working on drainage maintenance projects for council properties in East London and a 9 month drainage renovation and repairs project for St Thomas’s hospital. After several years learning his trade with time-served engineers, Jon became a lead drainage engineer for various drainage companies and in 1998 he and Angela became owners of a well-known plumbing and drainage franchise.

Despite having a team of 16, Jon preferred to be ‘hands on’, his love of all things drainage-related keeping him out on the road supervising the drainage engineers or filling in on jobbing when short-staffed.

In 2007 he and Angela sold their franchise to start Capital Drainage. Jon’s current role is to supervise the drainage engineers, manage and oversee repair and installation projects, maintain equipment and fleet as well as being hands on jobbing when required.

Angela began her working career in retail for John Lewis and then for Coca Cola, where a strong ethos in giving superb customer service was established. This skill has proved a vital tool for success in the drainage industry.

Angela and her husband, Jon, ran a well-known plumbing and drainage franchise area for almost 10 years, winning Franchise of the Year on several occasions and increasing from a starting point of 1 man in a van to a team of 16. In 2007 they sold their franchise area to start Capital Drainage Ltd, offering purely drainage services (their area of expertise) and aiming to keep the business small and personal.

Angela’s current role within Capital Drainage is to manage the finances and day-to-day accounting, health and safety, HR, and marketing, as well as keeping her hand in with customer liaison, booking of jobs, allocating jobs, and the day to day nitty gritty.

Mark Ambrose

Mark began his career as an apprentice plumber, and then took a completely different career path working on the buses as a driver and then Inspector. In 2000, having a good knowledge of plumbing, Mark went to work with Jon and Angela to assist in the running of their plumbing and drainage franchise as Operations Manager.

Mark very quickly learnt the fundamentals of drainage, attending training courses provided by Franchise Head Office in re-lining and CCTV surveying and by accompanying engineers on drainage works both day to day blockages and larger projects.

When Jon and Angela sold their franchise in 2007, Mark stayed to work with the new owners and then returned to the buses for a short while. As soon as Capital Drainage were in a position to expand Mark re-joined Jon and Angela to take over the day-to-day running of the office. His duties include: producing CCTV surveys, estimates, liaising with customers, booking in, allocating and managing work flow and job reporting; he has a passion for IT and technology.

Jason Light

Having gained his qualifications in plumbing, Jason began his career as the resident plumber/maintenance technician at the Royal Festival Hall. In 2001 Jason joined Team Ambrose, working for Jon and Angela as a Plumber. He began to take an interest in the drainage side of the business, preferring this to plumbing. Jason attended all the drainage courses that were available including re-lining and CCTV surveying and soon became a skilled and trusted member of the drainage team.

When Jon and Angela sold their franchise in 2007, Jason stayed on to work for the new owners for a short while. When Capital Drainage were in a position to expand, Jason was working for a national drainage company. He was our first choice of Engineer and he has worked with us again since 2010 as our Senior Drainage Engineer.

Jason is an NADC qualified drain surveyor and carries out the majority of our CCTV surveys. He is great at problem solving and alongside Jon is our most knowledgeable and senior engineer. Jason and Jon are credited with fully training Harry, our newest member of the team.

After attending college to learn plumbing and drainage, Jamie went to work full time with with his dad as an apprentice Drainage Engineer carrying out blockage clearance, repairs, and re-lining with a client base consisting of a number of local schools and the general public. Jamie’s dad, Colin, had worked with Jon and Angela in the past and is a firm family friend. Jamie would often come into the office in his younger years with his dad and has grown up within his family drainage business.

Jamie left his family business and was working for a local drainage and plumbing company before he joined Capital in 2014. Jon and Angela knew he had received training from an excellent time-served and highly skilled drainage engineer and a trusted family friend, Jon and Angela therefore seized the opportunity to employ Jamie when a position became available.

Jamies duties include blockage clearance both internal and external, high pressure water jetting, and drainage repairs. Jamie does mainly housing association work within the Maidstone area for 2 of our valued housing associations.

Harry is our youngest and newest member of the team. He worked for 2 days a week at Capital Drainage while studying for his City and Guilds level 2 diploma in Plumbing. In June 2014 , on successful completion of his qualification, Harry joined the team as a full time Apprentice Drainage Engineer. Harry would accompany either Jon or Jason on a daily basis learning all aspects of drainage, repairs, and CCTV.

In December 2015, Harry became fully qualified and took delivery of his very own van and over a short time, Harry became a trusted and competent member of the team. His duties mainly include internal and external blockage clearance, high pressure water jetting, assisting on repairs and excavations, and CCTV drainage surveys.

Harry is Jon and Angela’s youngest son and has grown up within the family business, so in some respects he has always been involved in drainage.
