Too Much Coffee

After a long time out from this forum drawn back to seek a bit of help. My Expobar Leva DB is feeling a little tired and in need of a service. Its had leaks in the past and needs some cleaning up, re-insulating and general smartening up. I've had it looked at by ex-Bella Barista engineers in the past, but life is too full to drive the thing out to them, I'd much rather find someone in London who can help. Anyone on this forum or recommendations of people you've used to keep your domestic E61 in good order?

In the absence of any personal recommendations you may want to take a look at the lists of service engineers in this thread.
