About consumer unit (fuse box) replacement in Northampton
Northampton is a large city of around 224,000 in Northamptonshire. The housing is mostly a mix of Victorian terraces, inter-war semi-detached housing and modern new-build estates. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like NN1, NN2, NN3 tend to be quicker jobs with standardised fittings. Local trade prices sit in the same ballpark as the UK average, with Northamptonshire firms quoting close to national rates.
East Midlands pricing sits a touch below the national average. Nottingham, Derby and Leicester are the higher end; smaller towns are noticeably cheaper. Plenty of Travis Perkins, Selco and Howdens branches across the region means parts rarely hold a job up.
Anything notifiable (new circuits, consumer unit swaps, bathroom zones, EV chargers) falls under Part P and has to go through an NICEIC, NAPIT or ECA registered electrician. Day rates run £200 in the regions up to about £400 in London. If your sparky can't give you a Building Control certificate at the end of a rewire or CU change, walk away.
