Participants are randomised to one of two groups in a 1:1 ratio using an online system (MACRO).

Resistive Fabric Warming (RFW) group: Participants receive Resistive Fabric Warming (RFW) during their surgery. RFW works like a low voltage electric blanket. A series of plastic coated, individually computer-controlled heating pads are used to warm the skin by direct contact. The pads can be placed both under the patient and over the parts of the body away from the operating site.

Forced Air Warming (FAW) group: Participants receive Forced Air Warming (FAW) during their surgery. FAW uses an electrical heater and a fan to blow warm air through a hollow paper duvet placed over the patient. There are holes in the duvet for the warm air to come out and heat the patient like a hair dryer. At the moment, most hospitals use this system.

Participants will be followed up for 90 days from the date of surgery by telephone contact and review of medical notes.
Primary Outcome(s)
1. Recruitment rate is recorded as the number of eligible participantswho consent to participate in the study within 90 days of surgery.
2. Definitive deep surgical site infection (SSI) rate is measured through clinical observations within 90 days of surgery
Secondary Outcome(s)
1. Superficial surgical site infection (SSI) rate is measured through clinical observations within 90 days of surgery
2. Inadvertent perioperative hypothermia (IPH) rate is assessed using temperature measurements during surgery
3. Health Economic assessment is assessed using length of hospital stay, patient reported outcome measures for quality of life score (EQ-5D-5L), resource utilisation and serious adverse events (SAEs) including death within 90 days of surgery
