Cardiff's change-of-use traffic runs both ways
In the year to its latest snapshot, Cardiff Council's register took in 237 commercial applications; 183 proposed a change of use and 15 sought to convert commercial space to residential. The recent examples are not all one direction. Offices and ground-floor commercial units are becoming homes, sometimes with a new shopfront treatment, yet one proposal turns a house into a ground-floor office with a flat above.
Another is a renewal of an existing permission for a mixed scheme with ground-floor commercial space and flats above. Renewals matter to lenders, because a site's value with live consent can be very different from its value once permission lapses. Where you are changing a building from one use to another, change of use bridging finance covers how the loan is structured around that decision.
Planning in Wales: no Class MA, different use classes
Class MA, the permitted development route widely used in England, is an English right and cannot be used in Wales. Wales also kept the older use classes, which is why Cardiff applications refer to B1 offices rather than Class E. In practice, most commercial to residential conversions in Cardiff need a full planning application through the council, and lenders will want to see either a decision or a credible planning case before lending against residential end values.
A bridge can buy the building on its existing use value while that application runs. Our page on bridging finance for planning permission explains how lenders handle that wait. Confirm the detail of any scheme with a Welsh planning consultant.
Budgeting for Land Transaction Tax
Purchases of commercial and mixed-use property in Cardiff pay Land Transaction Tax, collected by the Welsh Revenue Authority, with its own non-residential and residential rates. The figure can be significant on a larger purchase and has to be funded from your own resources alongside the deposit, because bridging lenders lend against the property, not the tax bill. Take advice from your accountant or solicitor on the LTT position for your deal.
Values, lenders and exits in Cardiff
Land Registry figures for the Cardiff City Centre area, to 30 June 2026, show a median price of £267,500 across all property types, from 5,195 sales, with prices up 0.9% on the year. As the capital and the seat of the Welsh Government, with the M4 and Cardiff Central close at hand, the city gives lenders a deep base of occupiers and buyers.
Exits are usually a commercial or buy-to-let refinance once a building is let, or a sale of converted homes. Our bridging versus commercial mortgage guide helps decide which loan suits each stage. Where you or a close relative will live in part of the building, the case may be regulated, and we refer it to a firm directly authorised by the Financial Conduct Authority.
