My latest stroke inducing phone call with my current insurers was when I considered getting a V Strom 650 either instead of or in addition to the 1250. They wanted £900 for the Strom. I then went to the comparison sites - £1200-£1400. I abandoned the idea rapidly. I have no circumstances to concern insurers beyond my postcode. The last two years only one insurer has quoted for my business.
The comparison websites work on the simplest lowest common denominator, ie. a post code, as a starting point. Start with them as a base point only; who knows you might get lucky.
If (or probably, when) this fails then contact some specialist brokers for their quotes. A good broker will listen to all your details and then do their best to marry you to an underwriter who is prepared (and able) to listen.
I have an E1 post code, which is central London. I had to go to two competing specialist brokers *. to give me a single multi-vehicle policy for three motorbikes, five cars and a motorhome. The cars vary between a VW Polo (kept on the street), a vintage Fraser Nash TT Replica *, a Porsche GT4 (kept on the street, outside my house), a Ferrari 360 (kept in storage but I can keep it overnight on the street) and the motorhome, stored in the open on a farm in Mill Hill (an hour away). The motorbikes are all garaged at home and include a BMW 1600 which was north of £20,000 when new. That is not a typical list of ownership but a
specialist broker managed to do it. It’s not cheap (north of £2000) but the vehicles are all insured and the policy is flexible. On the other hand, when bods are being
refused insurance or quoted well north of £1000 for only a single motorcycle, it maybe looks like very good value. Yes, several (not all, by any means) of the vehicles have to have good quality trackers (not some shonky crap off EBay) and, yes, I have to pay a subscription to the tracker company. Yes, I do have to declare estimated mileages. I don’t have business use or include commuting ***. I do include pillion cover. My licence used to be clean (five years) but I have picked up one SP20 since last renewal.
* The policy renews in mid-April, I am starting the process now. I shop around every year. If people (irrespective of their premium) cannot be arsed to shop around (ie. make at least an effort) then they will in all probability be over paying.
** Value? £350,000. This is actually the easiest to insure.
*** I will occasionally ride a motorcycle into the City and park it under our office, but that is not commuting on a regular basis. It’s no different to me occasionally riding to Tesco and parking it in their car park all day. I do sometimes park the bike on the street in London, but I use suitable security. I did not have to detail any of this to my insurer.
