St Mary the Virgin, Potters Bar

The original 1885 two-manual Forster & Andrews organ had been rebuilt, modified and enlarged on numerous occasions, and was still inadequate for the large building. The church had new plans to enlarge it even further, until we suggested they visit Derby, and inspect the fine three-manual Lewis/Walker organ, which was looking for a new home.

Once the church’s organist, Dave Miller, and their consultant, Paul Hale, had tried the organ and agreed it would be ideal, the plans were set in motion, Faculties approved, and instrument installed. The opening recital performed by Paul Hale, on March 14th 2020, to a large and enthusiastic audience proved to be very timely, only a week prior to the Covid-19 lockdown.

from Dave Miller, Organist St. Mary’s, Potters Bar

We were very fortunate to have the services of Henry Groves and Son for our recent organ works. Originally called in to enlarge our existing instrument, Jonathan suggested rehoming a redundant instrument instead. This proved to be fortuitous as we now have a superb three manual TC Lewis / JW Walker instrument which is far superior to anything which could have been achieved with our original organ. One thing of particular note was Jonathan’s sympathetic use of the church – which still had to be used during the work: services and other church activities were carried out with the minimum of upset. The cost was very competitive. Jonathan and his team showed the highest level of professionalism and care and were a pleasure to work with. I have no hesitation in recommending Henry Groves and Son.
