Chris Jackson,
Southampton Gas Service Engineer.


A little about us.

Kevin Jackson (Chris's father) commenced trading as Gas Adept during May 1994 with the aim of giving a superior level of service in most aspects of domestic gas utilisation - whether it be fitting your appliances or central heating, servicing or attending to breakdowns. Chris is a qualified gas operative and passed formal gas qualifications in 2005.

Southampton New Gas Boiler Replacement

Kevin had worked in the gas industry since 1974 and started as an apprentice Gas Fitter with Southern Gas (now part of British Gas), was 'apprentice of the year' in Southampton, took additional training to become a Service Engineer, Technician and then became a Technical Trainer. He has City and Guilds, an ONC and a HNC in domestic gas engineering.
Kevin also has business qualifications, namely a DMS and an MBA. Gas Adept Ltd is Gas Safe Registered for gas, electricity and energy efficiency - Gas Safe No. 116885.

Kevin decided to retire in 2021, completing some 48 years in the gas industry.

Chris now oversees the running of Gas Adept Ltd.

Chris is Kevin's Son, age 38 and lives in Hedge End. Chris has over 24 years of gas work experience and many long-standing clients remember seeing Chris from when he was as young as 12 years old (accompanying Kevin whilst on school holidays!) Chris studied 'A' Levels at Barton Peveril College and became a full time gas trainee with Kevin in 2003.
Chris became fully qualified as a gas operative during 2005 and is also Gas Safe registered.

Gas Adept Ltd are open to be regularly inspected by Gas Safe to ensure competency and compliance - your satisfaction, comfort and safety is their priority.

What We Do.

Southampton Heating Plumber

You may find other installers with cheaper costs where 'you get what you pay for' attitude (and some a lot more expensive!) but you will never match Gas Adept's quality for the cost given.
The name Gas 'Adept' is used as they're 'good with gas' and its applications.

Gas Adept Ltd are proud of their record in exceeding the needs and expectations of their clients. They strongly believe in giving the best customer service possible from a small family business and you really do get the feeling of satisfaction from your initial enquiry to the completion of your work.

For many years the John Lewis store in Southampton suggested that their customers contacted Gas Adept Ltd for their gas installation abilities when purchasing gas and electric cookers, hobs & ovens.

Further Information

More of our Credentials.

Gas Adept Ltd have many years of experience in repairing faults - breakdowns are remedied with minimal fuss and disruption. Heating systems can be updated, renewed or in some instances simply 'nursed' along to achieve their full potential and saving both the client money and our environmental impact.

Heating systems are a complex mating of parts and waterways - why for instance do you keep having to bleed your radiators? Why does the central heating water turn black over time? Why does your boiler make noises that 'kettle' and 'knock' in the background? These faults can be fixed by Gas Adept Ltd.

Gas Adept Ltd have always specialised solely in Gas Boiler Central Heating installation and maintenance - we do not diversify into other avenues like Air Source Heat Pumps, Solar, Underfloor Heating, Bathrooms or Building Maintenance.


May 1994 - Present

Gas Adept is established

By Kevin Jackson

Kevin leaves British Gas and buys his first van. Fully equipped with tools, Kevin started with a very small customer base that was built from word-of-mouth recommendations by colleagues, family, friends and neighbours.

Chris Jackson

April 1999

Chris begins 'Work Experience'

During secondary school

Chris opted to join Kevin on his daily rounds for a short period of time to gain a background on his father's job and this founded the platform for Chris' soon-to-be future.

July 2002

Chris becomes Gas Adept's first Apprentice

Full time Gas college placement

Chris joins an accredited gas training centre and began a two year full-time NVQ Level 2 Gas training course.


June 2006 - April 2018

Sarah joins Gas Adept

Kevin's Daughter

Having spent many years in a busy Mercedes-Benz dealership, Sarah left to join Gas Adept and underwent the tasks of day to day calls, emails and bookings. Working full time with Kevin and Chris for some 12 years, Sarah later married, started a family and left in 2018. This then enabled Kevin to naturally reduce his 'on the tools' work and concentrate on the less labour intensive admin role - whilst Chris continued providing Gas Adept's services.


June 2017

Bradley joins Gas Adept Ltd

Gas Adept's second Apprentice

Kevin and Chris knew Bradley from a very young age having serviced his family's boilers/heating systems. Bradley undertook gas work experience during 2017 and soon after became Gas Adept's next official apprentice. Employed full time by Gas Adept Ltd, Bradley assisted day-to-day operations including servicing, attending to heating/boiler repairs and assisting boiler replacements. For almost 7 years Bradley has been nurtured the ‘Gas Adept’ way.

March 2021

Bradley Qualifies

Gas Safe Regsitered under Gas Adept Ltd.

After almost 4 years of technical college tuition along with on-the-job training by Kevin and Chris, Bradley becomes fully qualified as an opperative under Gas Adept Ltd.


June 2021

Kevin Retires

After 27 years of running Gas Adept Ltd.

Having spent a couple of years of 'lighter' duties, Kevin retires leaving Chris and Bradley to continue Gas Adept Ltd and provide a first class service to all their clients - most of who have been clients since the beginning.

Kevin Jackson founded the name Gas 'Adept' for a reason: they are 'good with gas' and its applications. Gas Adept Ltd are proud with their record in meeting the needs and expectations of their clients. Gas Adept Ltd strongly believe in giving the best customer service possible from a Southampton local family business. You really do get the feeling of satisfaction from Gas Adept Ltd from your initial enquiry to the completion of the work.


May 2024

Our Anniversary

Celebrating 30 Years in business this year.

The arrival of 2024 brings great celebration as Gas Adept Ltd turns 30 years old. Established during 1994 in Hedge End, Southampton and still operating from Hedge End, Chris looks forward to offering all Gas Adept's clients another 30 years (and beyond!) of quality service and attentiveness.

Gas Adept would very much like to thank all their loyal clients and really appreciate the continued 'good old fashioned' word-of-mouth recommendations to family members, friends, neighbours and colleagues. Thank You to you all.
