Meet Our Directors

Pennine’s Directors come with a breadth of knowledge and experience from in and outside of the industry. They all share a common goal; commitment to create a customer-centric culture to deliver service excellence and maintain long term customer relationships.


Mark Tinnion - Managing Director

Mark joined Pennine in March 2014, bringing to Pennine a wealth of marketing experience and skill.

His 16-year career has included significant roles at companies including Intel Corporation and the Sony Corporation, where he was part of the team that successfully launched the Sony VAIO brand into the UK and the Pentium 4 Processor into Europe.

Mark has quickly made an impact here at Pennine, defining the company brand and Mission Statement. To enhance our customer service and experience, Mark has been instrumental in creating our dedicated Aftercare department to support our customers.

Mark also led and implemented a company restructure to enable us to redefine the double-glazing experience and set new standards of service for the industry.

Graham Jenney - Installations Director

Graham has played a major role in recent years helping to drive up the profitability of Pennine.

A qualified accountant, Graham joined the business in 2007 after previously being the Managing Director of Budget Windows, where he started as finance director but soon took on a wider operational role.

Graham has made the most of that experience and skill here at Pennine, driving up efficiency in the installations operation – resulting in an enhanced customer experience.

Improvements in procurement, as well as a restructuring of the department and the operational delivery pipeline, have made us a more efficient business – and a real winner with customers.

Derek McLaren - Sales Director

Derek found himself at the helm of the sales department in 2014 after a distinguished career here at Pennine since the company started in 2006. This has included a stint as Head of Retention and an award as Top Salesman in 2012.

Derek’s goal is to maximise sales for Pennine year on year, building on already-strong foundations, and to tap into technological advancements for his skilled salesforce.

As an experienced salesperson, Derek keeps the needs of our customers at the heart of everything he does, and has developed a huge understanding of their requirements.

Long term, Derek sees great potential in extending our popular product line in line with customer demand and market trends across the North East region.

Alan Oliver - Finance Director

Alan joined Crownfold Ltd, the parent company of Pennine, in February, 2000 and became a director in December, 2007.

After studying accountancy at Durham, Alan previously worked within a small partnership assisting with tax, accountancy, pension and estate issues of several entrepreneurs. Alan eventually reached partner level at the firm before leaving to work for Crownfold Ltd.

Alan’s current focus is to drive growth, profitability and modernisation here at Pennine, whilst delivering an exceptional service to customers.

Since working at Pennine, Alan has been instrumental in achieving 400% profit growth over 15 years and successfully completed the acquisition and merge of two major competitors.
