Heat Pump Installers Oxford: MCS and Heritage Rules

Oxford's suburbs are full of houses that suit a heat pump well. Its centre is full of buildings where getting permission takes longer than the installation. Work out which you have before paying for a design.

Oxford at a glance

Homes that are flats: 30.8% of Oxford households lived in a flat in 2021: 24.1% in purpose-built blocks and 4.9% in converted or shared houses, with the rest in other converted or commercial buildings. Source
How homes are heated: 75.7% of Oxford households heat with mains gas only and 12.1% with electricity only. Just 88 homes (0.2%) rely on oil alone and 320 (0.6%) on tank or bottled gas. Source
Historic buildings: Oxford City Council's heritage retrofit guidance (TAN 15) lists listed building consent and planning permission as the likely permissions for an air source heat pump on a listed building. Source
Local grant: Oxfordshire County Council runs the Warm Homes: Local Grant with Welcome the Warmth, for homes rated EPC D to G where household income is £36,000 or less or someone gets a qualifying means-tested benefit. Demand is high and new applicants join a waiting list. Source
Energy ratings: About 42% of homes with an EPC in Oxford are rated band D or below (median score 70, band C), against 47% across England. Based on certificates lodged in the 10 years to March 2025. Source

Listed buildings and conservation areas

Oxford City Council's heritage retrofit guidance, TAN 15, says an air source heat pump on a listed building is likely to need listed building consent and planning permission. Allow time for that and talk to the council's heritage team early.

Outside listed buildings, a single outdoor unit is usually permitted development. In a conservation area, it must not go on a wall or roof facing a highway. Many terraces in Jericho and central East Oxford fall in conservation areas, so check the council's map first.

Radiators and hot water

A heat pump runs at lower water temperatures than a gas boiler, so some rooms need larger radiators. The installer's room-by-room heat loss calculation decides which. You also need space for a hot water cylinder, typically where the old airing cupboard was.

Grants

Oxford households can claim £7,500 off an air or ground source heat pump from the Boiler Upgrade Scheme, whatever their income. Your installer applies.

Oxfordshire County Council also runs the Warm Homes: Local Grant for lower-income households in homes rated EPC D to G, and it can fund low carbon heating. Funding is limited and there is a waiting list, so register interest early.

How Oxford homes suit a heat pump

Victorian terraces in Jericho and East Oxford

Solid brick walls lose heat faster, and rear gardens are small. A unit against the back wall of the kitchen extension is common. Internal wall insulation on the coldest rooms can cut the size of pump you need.

Interwar semis in Headington, Cowley and Marston

These are often the easiest Oxford fit. The side passage or garden takes the unit, cavity walls can usually be filled, and the existing cylinder cupboard can hold a new one.

Flats and converted houses

Permitted development for a block of flats is tighter, and the freeholder must agree to anything on the walls or shared ground. A small air-to-air system or an electric upgrade may be more practical in a top-floor conversion.

Areas covered

Engineers who cover Oxford work across areas including Headington, Cowley, Jericho, Summertown, Marston, Iffley, Botley, Kidlington, Littlemore and Wolvercote.

Questions people in Oxford ask

Will a heat pump work in an old Oxford house?

Yes, if it is sized from a proper heat loss survey and the radiators are big enough. Older houses usually need some insulation and draught-proofing first. Our air source heat pumps guide explains the steps.

What does it cost?

Our heat pump cost guide gives national prices before the grant. Heritage permissions and larger radiators can add to the bill in central Oxford.
