Air conditioning in Baldock
We install, service and repair air conditioning in Baldock and the villages around it. The town has a medieval street plan full of listed Georgian houses and a large new neighbourhood planned to the north, so here's how planning works for each, plus parking and prices.

Of 56,732 households in the 2021 Census, 80 in 100 lived in a house (24 detached, 31 semi-detached, 25 terraced) and 20 in 100 in a flat. Most installs here are on houses, where a back or side wall is usually the simplest place for the outdoor unit.
In a conservation area an outdoor unit can't go on a wall or roof facing a road without planning permission, and an Article 4 direction can remove permitted development rights altogether. Check your postcode to see whether either applies to your street.

A Templar market town on old roads
North Herts Council's character statement explains Baldock's shape. A Roman settlement grew where roads crossed, centred on Walls Field, now a scheduled monument. In the 12th century the land was given to the Knights Templar, who laid out a new town, and a King's charter of 1199 gave it the lead over the older villages around it. The High Street and Whitehorse Street are so wide because they were the market places.
In the 18th century Baldock was at its height as a coaching town on the Great North Road, with eight maltsters and brewers. Their money rebuilt or re-fronted much of the centre in red brick with sash windows. The A1 bypassed the town in 1963 and the A505 in 2006.
The Baldock conservation area
Baldock has one conservation area, covering the town centre and its older streets. The council's 2003 character statement looks at five of them: the High Street, Whitehorse Street, Hitchin Street, Church Street and Park Street. It notes that the vast majority of buildings inside the area are listed. St Mary's Church is Grade I.
Most buildings sit on the pavement edge, with long, narrow medieval plots behind them, carriageways through to yards, and old maltings and outbuildings at the back. For an outdoor unit, that means the street side is out. A rear wall or yard is the usual answer, but on a listed building it needs listed building consent, whatever its position.
- High Street: three-storey Georgian town houses such as Clare House, the Manor House and Holford House
- Whitehorse Street and Hitchin Street: mostly two-storey houses and shops, some timber-framed behind later fronts
- Church Street and Park Street: smaller houses, cottages and converted maltings on narrow lanes
Planning: North Herts Council
Planning in Baldock is handled by North Hertfordshire District Council, which calls itself North Herts Council. Outside the conservation area, a heating-capable unit on a house is often permitted development if it isn't cooling-only, is no bigger than 1.5 m³ and passes the MCS 020(a) noise check of 37 dB(A) at neighbours' windows. Our planning guide sets out the full rules.
The council's Baldock town centre Article 4 direction, made in October 2022, only stops shops, offices and similar units becoming homes without permission. It doesn't cover houses or outdoor units, and listed buildings are left out of it.
Baldock homes and what they mean for an install
| Type of home | Where | What it means for the install |
|---|---|---|
| Listed Georgian and timber-framed houses | High Street, Whitehorse Street, Hitchin Street, Church Street | Listed building consent and a rear position. We plan the pipe route to avoid historic fabric. |
| Victorian and Edwardian worker terraces | Small streets outside the conservation area | Usually permitted development. One outdoor unit on the back wall or a ground pad. |
| Early 20th-century estates | Near the old industrial area, laid out on Letchworth Garden City ideas | Usually simple installs. A multi-split covers several bedrooms from one outdoor unit. |
| Flats in town houses and newer blocks | The town centre, including larger houses split into flats | Freeholder consent first, and listed building consent where the house is listed. |
| Later family houses | Estates on the edges of town | Check deeds and estate rules about external equipment. Otherwise usually straightforward. |
Growing Baldock: the new homes to the north and east
The North Herts Local Plan 2011–2031 allocates eight housing sites in and around Baldock, for an estimated 3,360 homes. The largest, Land North of Baldock (site BA1), is planned for about 2,800, with a link road and a new bridge over the railway.
In October 2025, Urban & Civic and Hertfordshire County Council applied for outline permission for up to 3,200 homes, schools, a local centre and a health hub across sites BA1, BA2, BA3 and BA10 (reference 25/02571/OP). When we checked in October 2026, the council's page listed no decision. If you buy there, check your plot's planning conditions and estate rules before adding an outdoor unit.
Businesses and parking
We fit and service systems for the shops, pubs, cafes and offices along the High Street and Whitehorse Street, many of them in listed buildings, and for workshops and offices in the converted yards behind. Commercial installs are done in business hours, and we handle the siting and paperwork first.
North Herts runs a residents' parking zone in Baldock, Zone A. The council's advice is that tradespeople ask the resident for a visitor permit or ticket, or apply for a parking dispensation if they can't. If your street is in the zone, tell us when you book.

Baldock questions
Do I need planning permission for air conditioning in Baldock?
It depends where you live. Outside the conservation area, a heating-capable unit on a house is often permitted development if it meets the limits. Inside it, a unit can't go on a wall or roof facing a road without permission. Most buildings in the conservation area are listed, and listed buildings always need consent. Applications go to North Herts Council.
Can I have air conditioning in a listed house on the High Street?
Often, with listed building consent. We look for a position in the rear yard or garden, plan a pipe route that avoids historic features, and give you the unit's size and sound data for the application. In some rooms a floor-standing console suits better than a wall unit, from £2,350 including VAT.
I'm buying a new home north of Baldock. Can I add air conditioning?
Usually, yes. Check the plot's planning conditions and the estate's rules about external equipment first. A heat pump that heats as well as cools is the right choice for permitted development. A bedroom unit starts at £1,850 including VAT, and two rooms on one outdoor unit from £3,650.
Do you cover Ashwell, Bygrave and Clothall?
Yes. They're all in North Herts, so planning goes to the same council. Ashwell has its own conservation area, where a unit can't go on a road-facing wall under permitted development, so we check the boundary before we quote.
How much is a service or repair in Baldock?
An annual service starts at £119 including VAT and keeps the manufacturer's warranty valid. If your system has stopped working, we confirm the cost of the repair visit when you book and price the repair in writing before any work starts. We can also regas a system once a leak has been found and fixed.
