About Monomark House.
We’ve been operating from our ‘new’ offices at Monomark House since the early 1970’s. Our original offices were in High Holborn way back in 1925. A great deal may have changed in our 90 years in business, but you can be sure, our great deals haven’t.

Take a moment to find out more about us.
Before considering signing up with a competitor ENSURE you watch out for misleading headline prices and always ask them about itemised charges – often hidden away or not mentioned at all. We’re not like that.

Typical ads say ‘Our Bronze Service costs only £8 per month entitling you to receive up to 25 letters’.

BUT what they don’t say is there is an itemised charge of £1 per letter. You could actually end up paying up to £33 per month!

Our equivalent letter charge is 14p to collect and 17p + p&p to forward.

That’s not the way we do business, but sadly there are many that do, and we hear from many people who end up paying way over the going rate.

cloud2I have just started using your scan and email service and was pleasantly suprised when I received a second email today, with what I assume was the second post. Great service – keep it up.

I have, over many years, been given an excellent, friendly and helpful service by the staff of BM. I particularly value the kindness in things done for me during my illness.
