What customers say

Based on genuine customer reviews

Fire door remedials, fire risk assessments and alarm installations form the core of the work customers describe, with reviewers in Cardiff repeatedly praising the speed and professionalism of the service. Several accounts highlight prompt attendance and efficient completion of jobs, whether upgrading fire door hardware, fitting a compliant front door, or fitting a new intruder system while taking out the previous one. Communication comes up often: enquiries are answered quickly, appointments are scheduled without delay and reports are issued soon afterwards.

Reviewers name Megan, Rhiannon, Ben, Nathan, Solomon and Josh W for their helpful and approachable manner, noting that queries are answered and that sound, practical advice is offered throughout. Tidiness is mentioned, with one customer recalling that the installer vacuumed afterwards, and the quality of the finished work is described as excellent, alongside written evidence that a door meets fire safety requirements. Pricing is characterised as fair and competitive, and the company is credited with accommodating a last-minute request when others had declined. A recurring theme is the calm guidance provided from the first call through to the completed remedial work, leaving customers satisfied with both the installation and the advice received.

The company I work for utilises Twenty4 Fire & Security for fire door inspections and remedial work, alarm installation and general maintenance and servicing of our fire system. I cannot fault the team at all, they are quick to respond, friendly and professional. They get the job done with minimum fuss. Highly Recommend

Good experience regarding a fire risk assessment. Communication, scheduling of appointment and issuing of the report was quick and professional & the feedback helpful

Firstly, and I find very important, the phone is answered by humans. From my very first phone call for a quote- which I received quickly and was a competitive price, an FRA and door surveys were able to be booked in (also quickly). Remedial work was needed and again I was given a competitive quote. I was guided throughout the process by Megan and Rhiannon. During our conversations their easygoing ( whilst professional) manner was able to guide and reassure me through something I’d never had to arrange before. Many thanks to both of them.

Twenty4 Fire and Security were invited to carry out some fire door works following a recent inspection of the block of flats. They attended promptly, carried out the work efficiently and in good time and ensured that the area was left clean and tidy before departing. The quality of the work was of the highest standard and I will be inviting them to carry out any further remedial works on other properties. I thoroughly recommend this company.

Engineers are good, however the communication from the office (Rhiannon in particular) is absolutely appalling. We’re still waiting on worksheets for a job completed in Nov last year, despite constant emails and phone calls chasing.

I contacted Twenty4 to install a new front door at my apartment which needed to comply with fire safety regulations. Twenty4 were very helpful, quick to answer any queries I had, and did a superb Installation, and provided me with written evidence that the door is fire compliant. A very hardworking and approachable company, would definitely recommend.
