Mate their coming to carry out an attachment and in all honestay if its a summary warrant there's not a thing you can do, i worked doing this for 6 years up till just a couple of year ago.

If you phone their office the wont stop it going ahead because once the order is granted then thats whats going ahead, when they come round they will listen to your proposals (think of one soon as). unfotunately they will price your gear up and they will now have a court order over them so any attempts to move them will leave you in contempt of court and they generally do sue for it.

now im not sure if they will accept your offer their it will probably go back to the office or court and generally unless your debt is quite high it will be accepted.

Sort out your income and expenditure, inflate your expenditure subtly not by big chunks and if you want to get rid of the debt and not just get the pressure of you make a decent offer

Dont just ignore it, they will get you if you dodge them. they can force entry wether your there or not and if you get really nippy about it they can obtain a exceptional attachment order (even essential items/non luxury) can be attached if they feel they need to they can uplift in the same visit (rare though)

Best o luck mate
