Air conditioning in Arlesey, Henlow and Langford

We install, service and repair air conditioning in Arlesey and the villages around it: Henlow, Lower Stondon and Langford. Here's how Arlesey's long High Street, its brickmaking past, the new homes planned east of the town and the Henlow conservation area affect an install.

Of 120,755 households in the 2021 Census, 86 in 100 lived in a house (29 detached, 34 semi-detached, 23 terraced) and 12 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 long town beside the main line

Arlesey is an unusually long, thin place. The Arlesey Cross masterplan, written with Central Bedfordshire Council, describes an extended north-south linear settlement, strung along one spine of Hitchin Road, the High Street and House Lane, with Church End at the northern end. The Church of St Peter there dates from the early 13th century and is listed Grade I.

The railway runs just west of the town. The first station opened in 1850, was renamed Arlesey and Henlow in 1933 and closed to passengers in 1959. Arlesey station reopened on the same site in 1988, on the northern edge of the town, with trains on the East Coast Main Line to London King's Cross.

Arlesey white bricks

Arlesey was a brickmaking town. Robert Beart opened a brickworks in the south of the parish in 1852, and by the late 1860s three more were working alongside the railway. They dug the local gault clay, and the perforated Arlesey White brick was patented in 1878. The main quarry is now the water-filled Blue Lagoon, and brickmaking in Arlesey ended in 1992.

That past is still on the street. The Arlesey Cross masterplan picks out the town's characteristic cream brickwork and its cream-brick Victorian terraces. Many of these houses were built without off-road parking, so tell us when you book if your street fills up with parked cars, and we'll plan where the van can unload the outdoor unit.

Where Arlesey is growing

Arlesey is one of the main places Central Bedfordshire Council has chosen for new homes. Arlesey Cross, allocated in 2011, covers land at Chase Farm, north-east of the High Street, and land west of it. The council's 2021 Local Plan then allocated land east of Arlesey for about 2,000 homes, a relief road and a country park. The road would run from Hitchin Road, south of the town, to a new link with the A507 in the north, taking traffic off the High Street.

The country park would keep a permanent gap between Arlesey and Fairfield, around the Blue Lagoon and the Green Lagoon. The plan also adds about 67 homes on land next to Lewis Lane and 20 behind 214 to 216 High Street. The council says a masterplan for the land east of Arlesey will follow, with more consultation.

New-build homes are usually the simplest to fit: sound walls, simple pipe routes and space at the side for an outdoor unit. Their planning permissions sometimes carry conditions about external equipment, so we check those, and the deeds, before we quote.

Planning: Central Bedfordshire Council

Arlesey, Henlow, Lower Stondon and Langford are all in Central Bedfordshire, so planning applications go to Central Bedfordshire Council. A heating-capable unit on a house is often permitted development if it meets the limits on size, position and noise. Cooling-only units, listed buildings and units on road-facing walls in a conservation area need permission. Our planning guide explains each rule.

Arlesey has no conservation area on the council's list and no Article 4 direction. Its neighbourhood plan, adopted in January 2018, is used alongside the council's policies when it decides applications in the town. Langford has its own neighbourhood plan too, adopted in 2021.

Henlow does have a conservation area, with an appraisal from January 2009. It takes in the Church of St Mary the Virgin, listed Grade I, and several listed houses. Inside it, a unit can't go on a wall or roof facing the road under permitted development.

Air conditioning for local businesses

We fit and service systems in shops, cafes, pubs, surgeries and offices along Arlesey High Street, and in business units and workshops across the area. Ceiling cassettes suit offices with suspended ceilings, and wall units suit shops and smaller rooms.

Commercial installs are done in business hours. We take over servicing from other installers, carry out F-Gas leak checks on systems that need them, and can regas a system once a leak has been found and fixed.

Arlesey and Henlow questions

Do I need planning permission for air conditioning in Arlesey?

Often not. Arlesey has no conservation area, so a heating-capable unit on a house can be permitted development if it meets the size, position and noise limits. You need permission for a listed building, a cooling-only unit, or a home whose planning permission removed these rights. Applications go to Central Bedfordshire Council.

I live in Henlow. Is my house in the conservation area?

It depends on your address. The Henlow conservation area takes in the Church of St Mary the Virgin and several listed houses, but not the whole village. The council's online map shows the exact boundary, and we check it before we quote. Inside it, the outdoor unit goes on a wall that doesn't face the road.

Can you fit air con in a cream-brick Victorian terrace?

Yes. The outdoor unit usually goes at the rear, with the pipes through the back wall. A multi-split runs two to four rooms from one outdoor unit, from £3,650 for two rooms and £5,100 for three, including VAT. Four rooms start from £6,500.

I'm buying a new build in Arlesey. Can I add air con later?

Usually, yes, and new builds are among the simplest homes to fit. Check the planning permission and your deeds for conditions or covenants about external equipment. If a management company looks after the estate, it may need to agree too. A single bedroom starts from £1,850 including VAT.

Do you repair and service air con around Arlesey?

Yes. We repair most brands, whoever fitted them. We confirm the cost of the repair visit when you book, and the repair itself is priced in writing before any work starts. An annual service starts at £119 including VAT, plus £59 for each extra indoor unit on the same visit.

Do you work with businesses in Arlesey and Langford?

Yes. We fit and service systems in shops, offices, surgeries and workshops, in business hours. Commercial wall units start from £1,795 plus VAT, and ceiling cassettes from £2,750 plus VAT. We also offer maintenance contracts for one site or several.
