Our experience

Set up in 2016, Hales & Coultas joined the Ongo group and has been providing high quality services to commercial and domestic customers in North Lincolnshire and further afield.

A team of 25 means we’re large enough to deliver the service you need – but small enough to offer that personal, customer centred approach to all our work.

Over the years we have expanded our offering, now specialising in renewable energy and electrical services.

Our team has over 30 years experience and the company is built on the heritage of two well known North Lincolnshire heating and plumbing companies – A.Hales Limited and J Coultas & Co Ltd.
