Jonathan Murton

Managing Director

Jonathan is a member of the Royal Institution of Chartered Surveyors (RICS), with over 20 years’ experience as both a surveyor and consultant to the building industry.

He is a qualified energy assessor, for existing and new buildings, and employs modern surveying techniques to apply his craft. These include CAD, 3D-simulation and building information modelling, as well as the use of unmanned aircraft for aerial surveys. In the past, Jonathan has trained up aspiring energy assessors and created bespoke courses for City & Guilds qualifications. He has also worked as an RICS counsellor for the Assessment of Professional Competence (APC) programme and as an advisor for the government’s Green Deal.

“I’m keen to provide an open, honest and top-quality service to my clients,” says Jonathan. “It’s building those relationships that really makes my work special, along with seeing my clients reap the benefits of a job well done.”

Caroline Lavelle

Operations Director

With a background in the retail sector, Caroline brings attention to detail and a drive for customer satisfaction to Murton & Co. She works closely with all our clients to keep an open line of communication, which helps operations run smoothly.

“The commitment to improving all areas of the business is something I love about the company,” says Caroline. “I care deeply about quality and excellence. I know how badly poor service impacts clients and their businesses, so it’s a great feeling when a client expresses satisfaction with the service they have received from Murton & Co, and even better when they place further instructions with us or we get a referral via a happy customer.”

Kelly Gannon

Administration Manager

Kelly joined us in October 2022 to support the team with our largest client.

The bulk of Kelly’s role involves liaising with team members, assessors and clients to arrange site visits and organise travel.

A self-confessed Excel enthusiast, Kelly loves working with spreadsheets almost as much as with people.

“No one’s getting out of here alive so enjoy life,” is Kelly’s favourite mantra and she believes that listening to clients while being friendly and kind is the key to excellent customer service.

Edward Trathen

Energy Assessor

Ed joined us in October 2025 as a SAP Assessor, bringing with him over two years of specialist SAP experience and a decade-long background as a site-based RdSAP Assessor. During those ten years, Ed worked closely with landlords and homeowners, advising on practical ways to improve property efficiency and boost Energy Performance Certificate (EPC) ratings. He also became a trusted voice in the industry, delivering talks and advice sessions for the Association of Residential Letting Agents (ARLA) and local property professionals’ organisations.

Ed carries out SAP and overheating assessments for new builds, extensions, and conversions. Known for his analytical mindset and creative problem-solving, he enjoys using SAP to help clients turn ambitious designs into compliant, energy-efficient realities. Always keen to expand his expertise, Ed is currently developing his skills further and will soon be able to undertake Thermal Bridge Calculations, yet another string to his bow.

“I take a very analytical approach and work through every detail until it’s absolutely right,” says Ed. “I’m a real stickler for accuracy, which is reflected in my 100% audit pass rate.”

When he’s not immersed in energy calculations or spending time with his family, Ed can be found at his local judo club. A passionate martial artist, he proudly holds a black belt in Judo, proving his discipline and focus extend well beyond the workplace.
