"New Worcester Bosch boiler installed. From the outset Mr Broom was polite, friendly and provided unbiased information on what was needed. Along with his two colleagues he worked in terrible weather conditions to ensure the work was carried out on time. On completion there was no mess and all rubbish had been cleared away. A credit to his profession and will use again without hesitation."
