About our basement & cellar steels service in Cheltenham
For homes in Cheltenham and the GL50, GL51, GL52 and GL53 districts, we handle basement & cellar steels from survey to sign-off. Our coverage runs across Gloucestershire, so nearby villages are included too. The beam is sized by a structural engineer and inspected before it is boxed in.
Underpinning and waterproofing are specialist trades, and we coordinate the steelwork with them rather than replacing them. Our part is the engineer's steel design, building control, temporary propping, and fitting the beams, columns and base plates at the right point in the dig, so the structure is sound before finishes go in.
Things to plan for
- Temporary works for basements are more involved than for a single opening. The design covers propping the house above, supporting the sides of the excavation, and keeping loads off freshly cast concrete until it has gained strength.
- Cellars often house gas meters, the incoming water main, the electricity supply and old drainage. These are mapped before work starts, gas work must by law be done by a Gas Safe registered engineer, and the electricity network operator may need to move a supply.
- Basements can stay damp even with waterproofing in place, so steel used below ground is protected against corrosion as the engineer specifies. That might mean an upgraded paint system or galvanising, particularly where steel sits close to external walls.
- A basement room needs a safe way out in a fire, which affects the stair, the doors and sometimes an escape window into a lightwell. Steel in the basement ceiling also commonly needs fire protection to the standard building control asks for.
- Basement steel frames often rely on columns because there is nowhere else to land the load. Each column sits on its own foundation or a thickened part of the slab, and its position needs agreeing early so it does not end up in the middle of a room.
How the job runs in Cheltenham
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building control and neighbours in Cheltenham
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Questions about basement & cellar steels in Cheltenham
What happens at the survey visit in Cheltenham?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
Can you work on older or listed homes in Cheltenham?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
How is steel protected from damp in a basement?
Steel below ground is protected against corrosion as the engineer specifies, which may mean a heavier-duty paint system or galvanising. It is also kept on the dry side of the waterproofing where possible, and fixings through the waterproofing are detailed so they do not let water in.
What paperwork will I get for basement steelwork?
You should end up with the engineer's calculations and drawings, the building control completion certificate, the waterproofing details and, where it applied, the party wall paperwork. Keep them together, as surveyors and solicitors usually ask for them when the property is sold or remortgaged.
Do I need a party wall notice for basement work?
In England and Wales usually yes, if you are excavating near a neighbour's foundations within the distances the Party Wall etc. Act 1996 sets, or underpinning a shared wall. Notice periods apply before that work starts. We arrange a party wall surveyor to handle the notices, though we do not give legal advice.
