Who we work with

Castlegate is one of the few web dev agencies that I consistently recommend. From top to bottom of the organisation they believe in great client service, and are always good value for money.

Dan Croxen-John

AWA Digital

First class company to deal with. Extremely professional in all aspects of web design and functioning. I am the owner of a Google 5 star rated E-commerce business and could not have achieved this without their expertise. Cannot rate them highly enough.

Joseph Woodhead

Dalby Firewood

Castlegate IT are by the far the most, knowledgeable, diligent and hardworking web development company I have had the pleasure to work with. Whenever they say something will be done, it's done sooner. They delivered a suite of websites which helped to position the Trust as one of the most recognised cultural organisations in the UK. Focussed, helpful and supportive, I would recommend Castlegate IT to any organisation.

Mike Linstead

York Museums Trust

Extremely professional service. All work was delivered on time and exactly as expected without any confusing jargon.

Sharon Scammell

Scammell Interiors

Castlegate IT is an incredibly helpful, creative, and responsive group; during the past decade they have helped us build precisely the website we wanted.

Dr T M Kemnitz

Royal Fireworks Press

Highly delighted with our website and very impressed with these guys. Very professional and give excellent customer service. Would always recommend.
