Problems with electrical re-wire in my home, with the knowledge after the event that the client can do nothing about it, since NAPIT requires you to re-use the same contractor to fix the problems. Would you after reading these pages? Manderson emails to us about re-wire.

We wrote the
concerns about the electrical work on 21.03.21;
Questions concerning electrics on 21.03.21 and
re-wire narrative on 19.04.2021
which had no effect on the credit card company or NAPIT. So we commisioned the following report to see if that will make any difference.
Pages 10, 11, 12, 13 contain information concerning the condition of the electrical installation of the complete rewiring of my home by Mr Manderson of Manderson Electrical Services Ltd, with the report by a qualified electrician and this statement about the work carried out:-
"The result of my observations and testing, I am recommending that all the fixed wiring be recovered and a complete new fixed wiring installation is installed. Unfortunately the work previously carried out is of such a poor standard I cannot re-use any of it."
Mr Manderson is a Part P Registered Electrician with Napit; Registered Competent Person Electrical; Approved Electrician from Napit; City & Guilds Qualified; Part P Electrical Safety; and Honest & Transparent. His firm was employed to replace all the wiring, power sockets, light switches and lights and make sure that rodents could not attack them to chew through the cables or cause an
electrical problem.
Pages 10 lists 18 electrical faults on the new wiring, re-use of the old wiring, and old wiring that was still either in use or had been cut at the old power socket, at the old light fitting, or old light switch (the plasterers filled an old power socket metal box and short-circuited the fuse - it will be fine in 30 minutes sir; 4 hours later it was still shorting, so presumably that would explain why they switched off one of the fuses in the old fuseboard - see photo on page 15 of the report. As clients; we do appreciate having the opportunity of electrocuting ourselves from their re-wire work) where

• fault 2 is a Code C1 'Danger Present' and immediate action is required from March 2021, (the electricians testing 2 of the double power sockets installed in the kitchen in 1987 found that they were polarity reversed. This risks a short circuit, shock or fire. They corrected the problem immediately)
• Faults 4, 12, 14 and 18 are Code C2 and Urgent remedial action required,
• Faults 1, 3, 5, 6, 7, 8, 9, 10, 11, 13, 15, 16, 17 are Code C3 where improvement is recommended

"Concerns about electrical work

The work was needed because we had an infestation of rodents and cables had been chewed through, so as well as restoring all power, arrangements to stop this happening
again were paramount. We are not confident that this has been achieved, but it is what we thought we were paying for.
Not all wires have been encased in a sheath and even when they have, there are still areas exposed. We relied upon Mr Manderson’s expertise to provide a very high level of protection
from rodents, so we would have expected other arrangements to be made to protect ends of the metal sheath:-

• 1. We provided wire wool, but little may have been used on only one hole in the wall in the lounge.
• 2. Photo 78 shows one of the new ceiling lights hanging out of the ceiling in the back bedroom. Besides the lighting cables to the ceiling being partially covered by
  metal codex trunking; parts of those 2 wires are unprotected. Does that mean that all the other new ceiling lights have sections of wiring leading to their
  transformers without trunking?
• 3. It would appear that all the new ceiling lights in the house for the top floor, bedroom floor, stairs and cloakroom, dining room, hall and lounge have these
  unprotected / untrunked cables between the transformer and light. Does this mean that every wire between the transformer and the new low-voltage light can be
  chewed through by rodents, which is directly against the contract?
• 4. There was an occasion when Chris has remarked that a hole had been left in the lounge ceiling and not filled in (The electricians cut through the ceiling
  twice in parallel to the hall about 6 inches apart see one cut in photo 58 with the other hidden by the batten to the left of it. They then removed part of the
  plasterboard between these cuts closest to the kitchen see photo 23. This would have have given them access to that space to bring the new wiring to where it
  was required. This exposed a large hole in the ceiling with old lath/plaster ceiling above the new plasterboard put below it. For safety reasons, they were told to
  batten the ceiling and put up a new plasterboard under this frame. When I pointed out for the new ceiling in the dining room that the new ceiling
  lights were longer than the depth of the batten and the plasterboard, so that if they did put them up then they would have to make holes in the old ceiling
  above, they were astonished. So I said if the battening is doubled would that get over the problem and they said yes. This would be okay if they did not take
  down the old ceiling lights leaving holes in the old ceiling for the rodents to drop down into a complete open box of new cables and exposed wire. We did not
  see the state of the old ceiling before the new ceiling was up under it in the Dining Room, nor in the lounge or extra walling in the back bedroom, dining
  room and front bedroom. Also, anywhere where the new cable came into or out of that ceiling through the side walls with no filling in of those holes would also
  provide access for the rodents.
  The following day I asked about the filling in of the other hole leading to the hallway in the ceiling before they would cover it with another section of new plasterboard.
  They said sorry, they had not got the wire wool from me, but if I provided it then they would squirt foam in the other hole then the wire wool and then more foam. I was not
  aware if they took down the new ceiling and filled in the other hole. I did not stay there and very quickly the plasterboard went up and in that last day, they installed
  new ceiling lights in the newly erected plasterboard, without me seeing that they had secured that hole). This undermines confidence that other holes have been blocked.
• 5. We provided 100 bags of anti-rodent poison so that each new light could have a bag alongside it, so that if a rodent got in it would probably eat it. Photo 20 shows you
  20 boxes with 4 bags in each. That means that in about 14 separate areas in the top floor, bedroom floor, ground floor and cellar that they had put down only 20 bags,
  when more than 20 new ceiling lights had been installed. Protection of wiring can also be carried by poison as well as by trunking.

Specifics:

• 6. There are two holes in the kitchen wall above the door from the hall with bundles of wire, none of which is sheathed - see photos 16, 17, 18, 37, 38, 39, 96, 97 shows
  exposed wires of brown, blue and bare for modern up to date wiring), 98, 99, 100 and 101. Jason said this was work in progress.
• 7. In the hall, close to the kitchen door, there is a switch on the wall between the lounge and the kitchen. The wire from that switch goes into the void by the cellar door
  with no obvious protection - see photos 103, 104, 105-111. We know that these void areas are vulnerable to attack.
• 8. There is a hole in the ceiling under the stairs with a bundle of wires including data
  wires which goes to the cellar stairs without protection - see photo 112.
• 9. At the bottom of the cellar stairs, there are wires - see photos 116 and 117 going to a junction box in the ceiling where new wires seem to be connected to old wires and
  new lights - see photos 118, 60, 61 and 62. Areas of this are not protected, but we were told the cellar was finished.
• 10. In the cellar, there are new power sockets with wire in plastic conduit - see photos 64, 65, 66, 119, 120, 123,124 but again, so is it all protected. ??? Photos 120, 121 and
  122 show that the wire comes out of the white plastic trunking and is then tacked to the wall round the corner before it goes up into the ceiling and probably into the acoustic
  wall built in the Dining room in Photo 73 without any trunking.
• 11. In the hall, there are wires in the wall by the dining room that are not protected.??? Would these not be plastered over??? See photos 138, 139 and 140. Yes they might well
  be plastered over, but these are in air gap behind the plaster so could be attacked by rodents, unlike the cable in the wall in Photo 103 which would be plastered over, but the
  cable above the ceiling would not be in photo 103. In looking closely at photo 139 the conductor colours are brown, black and grey, which is Three-Phase wiring. Why has
  new single phase and three phase wiring been used? Since “household wiring does not usually use three-phase supplies”.
• 12. On the main stairs, middle landing, there are wires not protected. See A in Questions concerning electrics.
• 13. Front bedroom new stud wall. Lights don’t appear to have any protection. No insulation visible
• 14. Ditto back bedroom In addition - see photos 74, 75 and 76, there is a light hanging from the ceiling with some codex, but also a length of unprotected wire see 1 above.
• 15. In the cloakroom, we are not sure if any of these wires go towards the second fuse box. No evidence of protection. New Fuse box 2 seems to have only the power from one
  socket downstairs in the hall on the old fuse board see section E on Questions concerning electrics. Is there any wiring between new fuse box 1 and new fuse box 2? If not then
  part of the new ceiling in the dining room will have to be taken down to accommodate this.
• 16. Given findings regarding insulation behind new walls see photo 73, is the dining room new wall sound insulated?
• 17. Also in the dining room, the wire for the pendant light (a 6 candle-shaped bulb candelabra) doesn’t feel as if it has codex round it - see photo 133.
• 18. Also there is wire for a light on the other side of the dining-room door to the gap between the new ceiling and the wall, which seems to be unprotected - see photo 137."

This undermines confidence that other holes have been blocked.

Photo 58 Looking at this photo on Tuesday 20 July 2021, there appears to be electic lighting between the new ceiling and the old. Does this mean, that not only have they left the old lights in the old ceiling, but also that they have left them connected? Does that mean that elsewhere where new ceilngs have been added, that not only will we be paying for electric light in the room below but also for electric light in the box above for the rodents to see where they are going?

Photo 121 taken on 18 March 2021.

In Photo 123 you can see an old double power socket with a new double power socket below it on the right. The Grey cable is inserted into the white plastic tube. This white tube goes to the other new double socket in Photo 124. The power cable then goes into another white plastic tube and up the wall to finish in Photo 120 where the new electrical power cable comes out of its protection, turns left and is tacked to the cellar wall until it reaches the second brick along to the right from the Arch brickwork as shown in Photo 122, where it then goes up into the ceiling and is still unprotected as shown in Photo 121.
All exposed cable was meant to have protection such as the white tubing or the Codex to prevent it being chewed by rodents.

Photo 122

Photo 73

In Photo 121 the new electric power cable gets inserted into the ceiling of the cellar. It then goes through to be behind the new stud wall erected by the electricians in the Dining Room above. This shows that new stud wall with its plasterboard screwed to it. I wonder if this new power cable is still unprotected in that stud wall.

When we have spent another £30,000, we will find out, since according to the statement by the person making out the electrical report, that since the job done was so poor, then

• everything including all the old and new wiring, the lights, light switches and replacement of old fiittings re-used by Manderson Electrical Services Ltd instead of them replacing them will have to ripped out and started all over again,
• thus causing full redecoration of the house after the plasterers have finished,
• removals of our belongings, storage and bringing them back by a removals firm after the work is completed,
• and re-laying of all the carpets.

• 11. In the hall, there are wires in the wall by the dining room that are not protected.??? Would these not be plastered over??? See photos 138, 139 and 140. Yes they might well
  be plastered over, but these are in air gap behind the plaster so could be attacked by rodents, unlike the cable in the wall in Photo 103 (see Photo 103 in point 7 above) which would be plastered over, but the
