What Our Hertfordshire Customers Say
"Sunlight lofts were as good as I could have hoped. They were organised, clear, helpful, and they did exactly what they promised.
Even the inevitable list of 'extra' spend was not that much and had all been mentioned through the build. The teams were friendly, skilled and tidy. The quote and paper-trail was great and I've recommended to everyone since. They were reassuringly almost-bored at the plan for our loft extension - clearly having done so many before that ours would be straightforward. And they were reasonably priced without cutting corners! Very happy. (detached house in Borehamwood, Herts)."
- Josh Coplee Herts, Jun 2025
"After meeting with various companies and then speaking with our neighbours (who had recently employed the services of Sunlight Lofts) we inspected the work carried out and decided to go ahead with our own loft conversion."
We found the company very pleasant and professional to deal with, from the initial meeting with Paul, right through to completion of the works. They started on the agreed date and finished 2 days ahead of schedule (only 4 weeks from start to finish) and we found all the team highly skilled. This is a very efficient loft company. Overall, we are extremely happy with the works carried out and felt we had made the right choice."
- Mr Omell, Hertfordshire, Sep 2024
