Founded as a garden city in the 1920s, it has a lot of interwar homes alongside later estates. Houses of that age, especially those that have been extended or rewired in stages, are often worth a full condition report before work or a sale.
Commercial work here ranges from the town centre and the Howard Centre to the offices and employment areas on the edge of the town. We handle testing, lighting upgrades, emergency lighting and installation.
