TCB Square

The TCB Square is designed to act as a cavity barrier around penetrations through the external wall of low-rise houses. Exceeding Part B’s EI30/15 requirement, the TCB Square is faster and easier to install, and provides a more robust solution, compared to using cut sections of linear cavity barrier or wrapping linear barriers around the pipe. The TCB Square performs the function of a cavity barrier around openings in the wall, not as a penetration seal or “fire stop”.

Katie Wills

Regional Manager

Meet Katie Wills, our vibrant Regional Manager who finds joy in spending time with her family, keeping fit, and taking part in fun-filled challenges.

With an energetic and outgoing personality, Katie thrives on trying new things, even venturing into coasteering in 2023 with her son.

She’s not afraid to push boundaries, whether climbing mountains (previously done Kilimanjaro) for charity or conquering marathons and skydives. I wonder what challenge is next on the list?

When not on an adventure, Katie cherishes time with loved ones, embodying a sociable spirit that brings warmth to our team. 

Madelaine Pieterse

Regional Manager

Madelaine has always worked in construction so she knows her way around the industry, but she will often get lost in her own town.

Born in South Africa, Madelaine swapped the stunning sunshine in Cape Town for the cloudy charm of Belfast. We’re not sure what made her make this decision, starting a new life in Ireland isn’t for the faint-hearted.

Madelaine is mother to two sons 22 and 25 who she loves to spend her time with, watching them mature into handsome men.

Grayson GB - Jim Martin

Jim Martin

Regional Manager

Our regional manager Jim likes to pretend that he is ‘pure Scottish’ but secretly he’s half English. Now, we ‘dinnae ken’ why he’s proud of his Scottish ancestry, but each to their own!

Despite his Scottish routes, Jim is great at his job, there’s no denying that.

You won’t often see Jim cracking up in the office, but we suppose there isn’t a lot to laugh at up in Scotland so he’s probably out of practice.

Helen Gibson

Regional Manager

Helen spends most of her time playing with her orchestra. She claims that her biggest passion is music, but then again, her instrument of choice is the flute.

Playing her flute isn’t the only music that Helen makes, she is the proud owner of a big laugh that bounces off every corner of the office. More often than not, you will hear her laugh before you see her!

Helen’s a single girl, and enjoys meeting up with friends for nights out at the cinema, eating out and keeping the local Brew Dog in business!! She says she doesn’t drink much…. we know different!

Kevin Jagg

Operations Director

Kevin has been in the construction game for a long time, over 30 years! He worked at Grayson & Co back in 1993 and has unfortunately known Tony throughout this time. Now he’s decided to join the senior leadership after knowing Clare and Chris for 18 years.

At the weekend, Kevin enjoys meeting friends for a beer or 3 and loves to travel all over the world on cruises.

Clare Spivey

Sales & Marketing Director

Although she won’t admit it, Clare has been in the game a long time.

Supplying power tools and fixings was her first job in the construction industry. Due to this she has the ability to spot a tool a mile off.

Clare must have been a magician in a former life as her ability to spin plates is quite something. With a husband who works away, 2 kids with a shed load of activities, her taxi and cheerleading skills are on hand most evenings and weekends.

Clare and her family enjoy escaping to Filey, where they enjoy long walks on the beach and eating fish and chips. Clare loves her holiday home as there is absolutely no phone signal.

Henry Bareham

Specification Director

Henry’s takes great pride in his family, a wife to whom he’s absurdly lucky to have been married to for over 30 years. And two children in their 20’s, who now talk to him having managed their way through the teenage years.

Having left his pretend job of 15 years as a fully-fledged P.G.A qualified Golf Professional, Henry has managed his last 20 years + in construction within manufacturing, technical specification, and sub-contracting.

He spends his time away from work trying to re-kindle the talent he had a long time ago on the golf course, whilst also managing a keen interest in the gym, trying to maintain the muscle to body fat ratio in a good way.

Chris Bentley

Regional Manager

Chris’s claim to fame is working with both Tony and Clare for over 24 years, and still being alive to tell the tale. He’s been working for Grayson since day one!

Outside of the office, Chris has a passion for music and plays in a Brass Band. He’s performed at the Albert Hall, and recently performed at Soccer Aid for Unicef in front of 70,000 supporters at Old Trafford.

If he’s not playing music or working, Chris does also like to watch Barnsley FC which unfortunately, doesn’t put a smile on his face too often.

Tony Higson ​

CEO & Managing Director ​

Having two teenage daughters, Tony enjoys spending much of this time working away.

He also has an old wife and new a Doberman, therefore the only time people value him is in the office or on site.

As a Sheffield Wednesday fan, the poor fella doesn’t get any joy there either.

Tony has been the Managing Director of Grayson for nearly twenty-years. For all of this time he was also moonlighting for ACS. Again, holding down two jobs was the perfect excuse for not going home.  

In a previous life Tony used to play solders, however he has very few war stories due to the fact his job was to the fix equipment real soldiers used.

Tony’s biggest fear is retirement.
