Before you get quotes for building work in Henley, check which planning rules apply to your home. Planning applications go to South Oxfordshire District Council, which has conservation areas covering central Henley, Reading Road and St Marks Road, and reviewed their boundaries in 2022. If your home is in one, or is listed, changes to the outside, such as new windows, doors or a roof covering in a different material, may need permission, and any work to a listed building may need listed building consent.
Not every Henley address is in South Oxfordshire. Remenham, across the bridge, is in Wokingham borough, where Green Belt rules limit extensions and outbuildings, and Fawley and Hambleden are in Buckinghamshire. Much of the countryside north and west of the town is in the Chilterns National Landscape, where new buildings and larger extensions are also more tightly controlled. Planning and building control questions go to the council for your address.
Flood risk matters too. If your home is near the Thames, check the flood risk for your address on GOV.UK before you commission drawings, as a planning application for an extension may need a flood risk assessment. Building the new floor level no lower than the existing one, and using flood-resilient materials low down, can reduce damage if water ever gets in.
Most building work in Henley falls into a few types:
- Renovating period houses in and around the centre, where matching the original brick, flint, lime mortar, joinery and roof materials matters.
- Loft conversions with a rear dormer on Victorian and Edwardian houses along Reading Road and St Marks Road.
- Extensions and kitchen extensions on later family homes on the edges of the town.
On terraced and semi-detached houses, work on or near a shared wall often needs a party wall agreement with your neighbours before it starts. In the narrow streets of the centre, plan access, skips and scaffolding early, and avoid Regatta week in the summer if you can.
When you compare builders, ask for itemised quotes on the same drawings. Check that each quote says who deals with building control and what the payment stages are, and never pay large sums upfront. Reviews on Trade Pilot are tied to real, invoiced jobs, so you can see how a builder has handled projects like yours.

Many single-storey rear extensions fall under permitted development. Conservation areas, listed buildings, flats, the Green Belt and the Chilterns National Landscape have extra limits. Check with the council for your address.
Wokingham Borough Council, not South Oxfordshire. Remenham is in the Green Belt, so check what's allowed before you commission drawings.
Often, yes, but a planning application may need a flood risk assessment, and the design should keep floor levels and services above likely flood levels. Check your flood risk on GOV.UK first.
Often, yes. If you're building on or near a shared wall, or digging foundations close to a neighbour's, you normally need to serve notice under the Party Wall etc. Act 1996 before work starts.
Avoid large upfront payments. Agree stage payments tied to finished work, and get a written contract that sets out the scope, price and timings.
Yes. Posting a job and receiving quotes is free for homeowners, and you don't have to accept any quote.
