Orders requiring calibration. Whilst we take the greatest care to get all orders dispatched and delivered to you in the stated time frame, orders received late afternoon and requiring calibration may on occasion miss dispatch that day, according to the complexity of the calibration. Be assured they will ship on the next dispatch, this in most cases should not add more than 24 hours to you delivery.

- Zones A & B - Mainland delivery rates apply.
- Zone C - Scottish Highlands.
- Zone D - Outer Hebrides, Orkney Isles, Shetland Isles, Isle of Man, Scilly Isles, and Channel Islands.
- Zone E - Northern Ireland
- Zone F - Republic of Ireland
