Did you know??

Did you know that uPVC and PVCu (or PVC-U) is the same thing?


uPVC was the standard term in the UK, and still is to many. It changed in the late 1980s to be consistent with Europe.


They call it PVCu, or PVC-U, because most European languages place the noun (PVC) before the adjective (U).


‘PVC’ stands for Polyvinyl Chloride and ‘U’ stands for Un-plasticised.

A word of warning....

Man showing his ID card

I hear many stories from customers who have found locksmiths online that turned out to be unqualified and inexperienced.

Or, someone has knocked on their door with a drill in their hand, quoting unnecessarily high prices off the top of their head.

Please be careful. Check your locksmith’s credentials, their ID, their qualifications and get a feel for their experience. Genuine online reviews on sites like Google and Trustpilot can be helpful too.

Many self-proclaimed locksmiths don’t know about regulations they should be following, for example complying with the fire regulations for flats.

They often also use cheap imitations of proper locks.

Make sure your locksmith is using genuine parts for all multipoint locking systems.

If they are like me, they will take pride in their work, really care about their customers’ security, and be happy to give you a 12-month guarantee for the locks they fit for you.

What my customers say

"Excellent service when we moved into our new home. Came fast and also gave us lots of good advice about our door - has also given me good advice over the phone when Anglian was a let down! Would definitely call again and recommend to family and friends".

D Sharpe

"Really really helpful. Absolutely knew subject in side out. Top quality work and products used and a very reasonable price. Very friendly, very tidy and solved a number of problems. And as a bonus we learn lots about wood. Couldn’t fault if I tried."

R Williams

"Came same day and fixed an old uPVC door lock that had failed. Very friendly and professional, explained clearly what he was doing and why.
The once awkward door locking mechanism now works a charm. I can highly recommend his services."
