Air Conditioning in Castleford

Most Castleford homes can have air conditioning fitted without planning permission, as long as the outdoor unit is 1.5 cubic metres or smaller, meets the 37 dB(A) noise limit and stays off the front of houses in the town's conservation areas. The usual request is a bedroom or loft room, often in a newer house that overheats upstairs.

Castleford's housing is a mix of former colliery terraces, interwar and post-war council-built semis, and large new estates on old industrial land around Glasshoughton and Allerton Bywater. Each type has its own installation pattern. Terraces in Airedale and Whitwood often have small yards. Newer houses usually have side access and modern wiring, which keeps the job simple. New-build houses are well insulated and can overheat in summer, especially upstairs rooms facing south or west.

Castleford is in the Wakefield Council area. Since 29 May 2025, air-to-air heat pumps on houses in England are permitted development under Class G, Part 14, Schedule 2 of the General Permitted Development Order 2015. A detached house can have two outdoor units under these rights, any other house one. Flats and listed buildings need more consents, and new estates sometimes have covenants about external equipment.

Wakefield Council lists 31 conservation areas across the district, including Castleford, Whitwood, Normanton and Knottingley. In a conservation area, an outdoor unit can't go on a wall or roof facing a highway under permitted development, so a rear wall or yard is the usual spot.

Worked example: checking the 1.5 cubic metre size limit. Class G measures the outdoor unit by its volume, including its housing. Multiply width by height by depth in metres. A typical single-room outdoor unit might measure 0.8m wide, 0.55m high and 0.3m deep: 0.8 x 0.55 x 0.3 = 0.132 cubic metres, well under the limit. Even a large multi-split unit at 1.0m x 1.4m x 0.4m works out at 0.56 cubic metres. The size rule rarely stops a home installation. The noise limit and the siting rules are the ones that do. The dimensions above are for illustration, so read the real figures from the data sheet of the model you are quoted.

The noise rule uses the MCS 020 a) calculation, which estimates the level at the neighbour's nearest habitable room window from the unit's sound power, its distance and any barrier in between. On a terrace with a small yard, that calculation decides where the unit goes. Ask your installer to show you the result.

Our partner installers are MCS certified and apply the 0% VAT rate to domestic air-to-air heat pump installations, which most modern split systems are. HMRC's VAT Notice 708/6 sets that zero rate for homes until 31 March 2027. MCS certification is also what you need if you plan to claim the Boiler Upgrade Scheme grant.

Commercial work centres on the retail and leisure at Xscape and Junction 32, distribution units by the M62, and shops and food outlets in the town centre around Carlton Street.
